Platinum Jubliee of TAI : A milestone to be proud of! On 9th April 2014, The Textile Association (India) will celebrate its 75th Birth AnniversaryThe Platinum Jubilee, in Mumbai during which a befitting program is chalked out under the able leadership of the National President of TAI, Mr. D.R. Mehta. The next issue of the JTA will describe about the celebration evening and what transpires there. However, on behalf of the readers of JTA, the Editor and the Editorial Board we wish the function a grand success and pray that the Textile Association( India), continues to play a paramount role in enlightening the Textile Industry Professionals as well as Research Scientists, Educationists and all other stake holders of India's mother Industry. Established in the year 1939, with 8 founding members, today TAI boasts the membership of over 23,000 spread around 26 Units throughout the length and breadth of India. It can be understood that not all these Units working with Autonomy under federal structure are vibrant in activities. However, 50% of them are well functioning as the torch bearers in their area guiding the textile professionals and the Industry with regard to latest developments in the Textile field, policy changes and challenges of their clusters with remedial measures. This activity of updating the stake holders of Textile Industry in a number of emerging areas such as Technical Textiles, Home Textiles, Sports Textiles, Nonwovens, Continuous Processing, Eco-friendly processing and the need to conserve energy and all other utilities like, water, steam, power etc. for cost reduction and also from the sustainability point of view is truly valuable. Towards this end, various Units of TAI organizes number of local and zonal seminars, conferences, training workshops, factory visits, visits to Textile Machinery Exhibitions etc. so that the decision makers as well as the textile professional are made aware about the latest development in the manufacture of textile fabrics and apparels. The emerging areas with12 different segments under the umbrella of Technical Textiles have created significant interest among the businessmen who are ready to invest. While they do so, the Government of India is equally taking positive steps to create a supporting environment through schemes like TUFS, Technical Textile Mission, Integrated Textile Parks and the schemes like Skill Development. TAI has been holding All India Textile Conferences since 1944 during which it also honors those Units which are best performing; it honors selected friends on the National level for service mementos and service gold medals for their contribution to the growth of the TAI. It also confers Honorary Fellowship of Textile Association on those distinguished individuals who have made significant contribution in the field of Textile Education and Industrial research and Management of Textile Business. The Journal of the Textile Association started in the year 1940, when it was known as Textile Digest, has also acquired its own position in serving the stake holders of the Indian Textile industry by keeping them abreast about the technological developments as well as success stories of innumerable textile professionals and has become the mouth piece of the

Association. Today we find it internationally known and respected as a Technological and Industrial research journal which most of our readers and members love to have it. Thanks to the internet and the developments in communication that we have been able to make JTA available online, without involving any additional burden on the readers. The work of Professional Award Committee and those who are taking the Diplomas as ATAs and GMTAs has been equally rewarding. Though the book publication process had been slowed down, it is very recently gathering required momentum. The Textile Association (India) organized the World Textile Conference in the year 2011 in Mumbai under the same leadership team and it was exceptionally a grand Success mainly in terms of the quality of papers, the stage show of the two days, the organizational capability and above all the kind of revenue it generated for the welfare activities of the Association. In fact it is this success of the World Textile Congress which has triggered the present team to take up the challenge of organizing another Global Conference on the foreign soil at Bangkok (Thailand). As soon as the conditions in that country improve, TAI is seriously planning to hold such conference there. So friends, the Textile Association (India) have grown strength to strength in its membership, in its diversity of activities and its penetrating influence in the lives of Textile professionals. However, as the world scenario of textile is changing, the Association also has to invent a new plank of functioning. It must strengthen its Central Office with capable manpower who can establish linkage with Academia, Industry and the Government Agencies with equal ease and familiarity. It should be able to Network internationally and become advocate of various issues related to the Textile Industry on different forums and when this body opines on certain issues, the credibility of it needs to be very high. I see there is a lot of room in galvanizing the image of the Textile Association (India) making it increasingly relevant and in tune with fast changing world of Textiles, Clothing and all its allied fields. While we all deserve to be Congratulated on this land mark of TAI, we must be conscious that the road ahead is truly challenging in a fierce international competition and its only the Quality of Service, Credibility of our opinions and our Brand Image which will matter the most, for which we need to chalk out specific road map with definite goals which are specific, measurable, realistic and time bound. Once again CONGRATULATIONS The Textile Association (India) and all its members!

Fire Retardant and Mosquito Repellent Jute Fabric Treated with Thio-urea S. Basak*, Kartick. K. Samanta, S. K. Chattopadhyay, R. Narkar, M. Bhowmick , S. Das & A. H. Saikh Chemical and Biochemical processing division Central Institute for Research on Cotton Technology. Abstract A flame retardant finish using thio-urea, resin formulation has been prepared for application on jute fabric. Thio-urea and resin was applied in different concentrations to raw jute fabric by padding and drying method. Flame retardancy of the treated fabrics was compared with control fabric in terms of temperature generation, vertical flammability and limiting oxygen index (LOI) determination. Compared to control jute fabric, LOI value was found to increase by 1.9 times after 80 gpl application of thio-urea resin. As far as the vertical flammability is concerned all the treated fabrics showed low burning rate and showed less fabric temperature compared to the control fabric. Thus at 80 gpl thio-urea resin application, burning was stopped and reduced char length was observed. Washing and weathering durability of the treated fabrics were evaluated as per standard method. Beside the flammability results, temperature generation curve, cellulose-resin reaction mechanism, thermogravimetry (TG) and FTIR analysis of the control, treated and washed fabrics were also compared and commented. Mosquito repellent property of the control and treated fabrics were evaluated quantitatively by cage test. Physical properties of the control and treated fabrics were also evaluated by tensile strength, yellowness index and brightness index.

1. Introduction Jute is one of the most important biodegradable, ecofriendly, annually renewable agricultural product and natural textile fibre [1]. Apart from its traditional use as packaging material, jute fabrics are now widely used in furnishing textiles, upholstery and home textiles [2]. Jute is a natural fibre composed of cellulose, lignin, hemicellulose, waxes and protein mineral matters [3]. However being a cellulosic fibre, jute ignites easily and in fires jute products such as curtains, upholstered furniture, home textile products, automobile interior products become quickly damaged and are difficult to extinguish [4]. Since consumers are now increasingly aware of safe life style, expectation and demand for diversified value added flame retardant jute products are steadily increasing. In addition to fire retardant property, mosquito or insect repellent jute products are also increasing because it increase the life of the products and enhance the application of

the jute products as home textile, home furnishing purpose. Therefore effort is going on to develop fire retardant and mosquito repellent cellulosic fabric for home textile and home furnishing application [5]. Different chemical formulations have been reported for preparing fire retardant jute fabrics [6]. It has been found that different inorganic salts [6,7,10], borax-boric acid composition [8,10], hydrated metal oxide like sodium silicate [9] different phosphorous and nitrogeneous compound and their combinations has been mostly used to make fire retardant jute [10]. Studies also have been reported on the application of nitrogen and sulphur based thiourea on jute fabric and their flame retardancy properties were also evaluated [11]. However among the reported technologies, many of them are nondurable to weathering and washing. It has also been reported that thio-urea can act as antibacterial, antimalerial for pharmacological applications [12,13]. However till date no proper study on the temperature generation profile of control and thiourea, resin formulation treated fabric, detail washing and weathering fastness property of thio-urea on cellulosic fabric, mechanism of reaction of thio-urea resin formulation with cellulose and the use of this formulation for mosquito repellent finishing of any textile fabric has not

FINISHING been reported in the literature to the best of our knowledge.

2.3 Testing methods 2.3.1. Flammability test Flammability activities of the treated fabrics were evaluated by the standard methods. For LOI analysis, IS 13501 test was used .Vertical flammability of the control and treated samples have been measured by using 11871 method A in terms of flame time, after glow time and char length.

Therefore, in this study application of thio-urea for developing dual functionalities such as flame retardant and mosquito repellent on jute fabric has been reported. The process would also help to reduce the processing cost, time and effluent load as single chemical perform dual functionalities. In this paper the results of the investigation on the use of thio-urea and thio-urea resin as fire retardant on the jute fabric has been reported. Besides, detail washing and weathering fastness properties of the thio-urea resin formulation also have been discussed. The mechanism of developed flame retardance and fastness properties was supported by chemical reactions, temperature generation curve, thermo gravimetric analysis (TGA) and FTIR analysis. Further mosquito repellent property of the control and treated fabrics were evaluated by quantitatively using most commonly used cage test method.

2.3.2. Durability of finish to washing Fire retardant activity of the finished fabric was evaluated after washing ( ISO 2) the sample in a laundrometer using neutral soap 5g/l at 500C for 45 min. The fabric was then rinsed in the fresh water for 5 min, followed by drying at 1000C for 5 min. Then, it was kept in a desiccator for 24 h for conditioning before the flammability test. 2.3.3. Weathering durability Treated and untreated jute fabric samples were exposed directly under sunlight without any protection from weathering, but was protected from rain for 6 h each day in the month of December and continued for 180 h. After every 30h LOI values of the specimen were evaluated.

2. Materials and Methods 2.1 Materials 270 GSM plain woven fabric of 12 EPI (ends/ inch), 13 PPI (picks/inch) with 200 tex warp and 240 tex weft counts, procured from the Mumbai local market was used in the study. Thio-urea, DMDHEU resin and MgCl2 used for the treatment was supplied by Qualigens Fine Chemicals, Mumbai.

2.3.4. Mosquito repellency test Both the control and the thio-urea treated fabrics were placed inside the mosquito cage containing 25 mosquitoes for 2 h. The effectiveness of the finish is evaluated by depending upon the number of mosquitoes landed over the surface of the fabric with every 30 min interval of time.

2.2 Experimental Methods The raw jute fabric sample was submerged in 1 lit water at room temperature for 3 h, then dried and conditioned at normal room temperature and 65% humidity for 12 h. The fabric samples were impregnated with different formulations of thio-urea in concentrations of 20, 40, 60 and 80 gpl at room temperature with material to liquor ratio of 1:10 padded to provide a wet pick up of about 100% and then dried at 1100C for 5 min.

2.3.5. Thermogravimetry Analysis The thermal stability of the control and thio urea treated jute fabrics were investigated by using thermogravimetry analyzer, model-METTLER TOLEDO TG-50/ MT5. 2.3.6. Temperature generation analysis Maximum temperature produced during burning of sample was measured using IR thermometer, Fisher Scientific made (Model No. 15077968 FB61354 225PE) in non-contact mode. Both the control and the treated fabric were ignited vertically with 38 mm flame for 10 s time. Then the temperature generated from the ignited fabric was plotted in the curve with respect to time period. 2.3.7. FT-IR Analysis The control and treated jute fabrics were analyzed using FTIR spectroscopy, Model Shimadzu FT-IR spectrometer (IR Prestige-21) to find out different chemical groups.

Fresh fabric samples were impregnated with following formulation at room temperature with material to liquor ratio of 1:10 padded to provide a wet pick up of about 80% and then dried and cured at 1100C for 5 min and 1400C for 4 min. Thio-urea- 80 gpl DMDHEU resin- 40, 80 gpl MgCl2- 20 gpl Before testing all the finished jute fabric samples were conditioned for 48h, 65% RH and 270C. 274

thio-urea and further increasing with increase in the addon. Thus at 6% add-on, the LOI value of the treated jute fabric is about 40 which is almost 1.9 times of what was obtained with the control fabric. It can also be observed from Table 3.1 that in case of vertical flammability, the control jute fabric burnt with flame within 1 min whereas the 40 gpl thio-urea treated jute fabric consumed 20 min for complete burning. Like LOI value this vertical burning behaviour also gradually improves with increasing thio-urea concentration. This phenomenon can be clearly observed from Figure 3.1; with increasing add-on of thio-urea on the surface of the jute fabric, the burning rates of the treated fabric get reduced. Thus at 80 gpl application i.e at 6% add-on, fabric did not take any flame and smoke and 15 cm char

2.3.8. Physical testings of treated fabric Tensile strength, one of the important physical parameters, of the treated and control fabrics was evaluated by using Instron tensile tester as per the ASTM D 5035 method. Brightness index of the samples have been measured by TAPPI 452/ ISO 2470 method. Yellowness index was measured by using ASTMD 1925 method. 3. Results and Discussion The results of the flammability testing of both the control as well as the jute fabric treated with different concentrations of thio-urea have been presented in Table 3.1.

3.1. LOI and vertical flammability LOI, a measure of flammability of the samples, is the minimum amount of oxygen in oxygen/ nitrogen gas stream mixture that support combustion. Fibres having the LOI value of 21 or below ignite easily and burn rapidly in air. Those with LOI values above 21 ignite and burn slowly and when the LOI values increase above 26, fibres may be considered to be flame retardant [4]. The effect of thio-urea on flame retardancy can be assessed by considering the LOI values of treated samples vis-a-vis the control sample. It can be seen from Table 3.1 that the LOI value of control raw jute fabric is 21, whereas the treated samples have the LOI values increasing to almost 1.4 times after only 1.6% add-on of Jan - Feb 2014

length has been observed. The possible reason for flame retardancy might be the fact that thio-urea [SC (NH2)2] is an organo sulphur compound and on heating it releases ammonia, nitrogen oxide, water and sulphur oxide which protects the cellulose substrate from getting affected by O2 supply, thus increasing the LOI value [14,15]. Further the sulphur oxide formed reacts with O2 at high temperature and produces highly reactive SO3, which reacts with water and form sulphuric acid with heat [16, 17]. This sulphuric acid might be helping to dehydrate cellulosic jute by carbonium ion mechanism and enhanced char formation [18]. 275

3.2 Flammability and wash durability The results of the flammability testing of both the control as well as the jute fabric treated with 80 gpl thio-urea and resin formulations have been presented in Table 3.2.The effect of thio-urea and DMDHEU resin i.e cross linking agent on flame retardancy can be assessed by considering the LOI values of treated samples. It can be observed from the Table 3.2 that LOI value of (thiourea and resin) treated fabric is 4-5% higher than only thiourea treated fabric. It might be because of DMDHEU resin, which helps to provide additional nitrogen and thus help to enhance the LOI value [19]. Figure 3.2 represents the vertical burning behaviour comparison of the control and the treated (B) samples. It can be observed that the control jute fabric was burnt within 1 min whereas the treated fabric showed no flame and as well as no glow and smoke. Durability of the imparted flame retardant finish to washing was studied to evaluate its effectiveness in some of the application where the sample may undergo to limited washing cycle. The 8% thiourea and [80gpl thio-urea+ resin (40 and 80 gpl)] treated jute fabric samples were taken for standard washing cycles. It was observed that after soap washing, there was significant change in flame retardant properties of the only 80gpl thio-urea treated fabric (E). It can be seen from the Table 3.2 that in only thio-urea (80gpl) treated sample the LOI value decreased from 40 to 23 after soap washing. This could be attributed to

Figure 3.2: Vertical flammability of control and (80gpl thiourea+ 80 gpl resin) treated jute fabric

the removal of thio-urea from the surface of the treated fabric because of its solubility in water [14]. However, the measured LOI value of 32 in the washed sample C was 39% higher than that of 23 measured in only thiourea (80gpl) treated sample after soap washing. This might be attributed to the lesser removal of thio-urea from the fabric after washing, due to linkage formation with cellulose and lignin as shown by the mechanism and discussion in Figure 3.3. In the case of vertical flammability test sample C showed flame for 20s, however afterglow was present in the sample. As a result of this, the sample burn completely at very slow afterglow propagation rate of 24.2 mm/min in 620 s, which is almost 10 fold slower than the control fabric. As a result end user will get more time to escape from fire hazard zone. It can also be observed from the Table 3.2 that after 5 washing (sample D) LOI reduced by only 15% compared to the 1 wash sample for sample C. As far as the vertical flammability is concerned, it took more than 300s for complete burning whereas the control sample burnt within a minute. Therefore, it can be said that DMDHEU cross-linking agent helps to retain the thiourea partially on the surface of washed jute fabric. As a result treated fabric showed moderate fire retardant properties even also after washing.

treated fabric is concerned it losses around 10% LOI value after one month exposure to outdoor sunlight. It might be due to the partial decomposition of thio-urea due to MgCl2 catalyzed lengthy heating at outdoor sunlight [20].Another thing we have observed from this experiment is that after sunlight exposure (90 h), odor coming out from the treated fabric is more compared to the control fabric. It might be due to the formation of gases like sulphur dioxide, ammonia, hydrogen sulphide, carbon di sulphide, ammonium thiocyanate etc. on heat decomposition of thio-urea formulation [21].However this pungent chemical odor might be more effective for repelling mosquitoes and insects.

*Total burning time of the fabric = combustion with flame time + combustion with afterglow (after flame stopped) 3.3 Weathering durability Durability of the imparted flame retardant finish to weathering was studied to evaluate its effectiveness in some of the applications like curtains, home furnishings where the sample indirectly may come in contact of sunlight.

FINISHING 3.4 Thermogravimetry (TG) Analysis

control jute fabric (A), thiourea treated jute fabric (B) loses almost same mass below 1500C. In the second stage of the curve, it started to loss its mass due to pyrolysis from 2100C, which is quite below (550C) than the degradation temperature of the control fabric. Hence, it can be deduced from the curves that the applied thiourea reduces the combustion temperature of the polymeric substrate and dilutes the flammable volatiles by the generation of non-flammable volatiles such as NH3, CO2, NO2, and SO2 at comparatively lower temperature and increased the LOI values of the treated fabric. Thiourea also had an additional effect on char formation. Compared to control jute fabric, treated fabric [8% thiourea + 8% resin] started early char formation and increased the total amount of char formation from 13 to 32% at 5000C temp. So the formation of nonflammable gases and char formation, both of these phenomena help to increase the LOI values and improve the thermal behaviour of the treated jute fabric. It can be observed from curve C and curve D that in both cases, it started to loss its mass due to pyrolysis from 2600C, which is more than curve B and almost similar to curve A. However rate of degradation of the polymer at 2600 C is less than the control fabric and the amount of char residue left at higher temperature is 10% more, compared to the control fabric. Both of these phenomena again support the interpretation that after washing thio-urea was not fully removed from the treated jute fabric and as a result, LOI values and thermal behaviour of the washed fabric is higher compared to the control fabric. As far the curve E is concerned, rate of degradation of the polymer at 2600C is more than the curve C& D and the amount of char residue left is also less than C& D. It reflects the poor wash fastness properties and after washing thermal properties of the sample E and it is almost similar to the control sample. It might be attributed to the absence of resin in that particular formulation. Therefore it can be concluded that DMDHEU resin used in the formulation B helped to retain the thermal stability after washing.

Thermo gravimetric analysis (TGA) method was applied to measure the effects of thio-urea on the thermal degradation and charring behaviour of the treated fabrics. Figure 3.3 shows that the TGA curves of the control jute fabric (A) [80 gpl thiourea+ 80 gpl resin], treated jute fabric (B) [80gpl thiourea+ 80gpl resin], treated jute fabric after one wash (C) [80 gpl thiourea+ 80gpl resin], treated jute fabric after five washes (D), 80gpl thiourea treated jute fabric after one wash (E) and only thiourea (F). The test was carried out in N2 atmosphere at a heating rate of 100C/min. It can be seen that the Thermo gravimetric (TG) curve of pure thio-urea showed two steps of weight loss. The initial degradation takes place at 2000C, with 70% weight loss and followed by another weight loss at about 15% at 2600C. After 2500C, there was no significant change in its weight till 5000C. Initial weight loss might be attributed to the melting and evaporation of thio-urea [20]. The TG curves of the control jute fabric (A) exhibited three distinct stages, the initial stage at a temperature of below 1500C. This is mostly due to physical change and due to the loss of absorbed moisture from the polymer (cellulose & hemicelluloses) [16, 17]. However, in second stage, mainly pyrolysis occurred over the temperature range 265- 3500C. In this stage mass loss is very fast and significant. Most of the cellulose pyrolysis products are known to be form in this stage [22]. As jute is a lingo-cellulosic material and predominant component is cellulose, hence pyrolysis might have taken place. In the third stage, above 3500C, dehydration and char formation occurred. As compared to

FINISHING Thus the treated fabric delivered 70% mosquito repellency effect compared to the control fabric after 60 min. After 90-120 min observation no mosquitoes were present on the treated fabric surface. However some of the mosquitoes were moving just surrounding the surface of the treated fabric. In contrast, control fabric showed no repellency against mosquitoes as the number of mosquitoes present on the control fabric surface increased with time interval.

Table3.4: Observation of mosquito repellence in cage test Observation time interval (min)

Figure 3.4: Temperature generation profile during burning of control and treated (B) jute fabric

Figure 3.4 showed the temperature generation curves of control loom state jute fabric and treated (B) jute fabric. In case of control fabric initial temperature generation was high around 400-450°C as the fabric was burnt with flame whereas in case of treated fabric only 100°C temperature generated from the small burning part of the fabric during 1st 20 s of ignition due to absence of flame. Only slight afterglow present in the treated fabric was responsible for it. After 50 s after-glow also stopped and the temperature showed rapidly fall down to room temperature within the interval of 20-30 s. In contrast control jute fabric was burnt with flame up to 35 s with 350450°C temperature generations, after that strong afterglow was present in it. It showed temperature around 250-300°C. Beyond 60 s afterglow was also stopped and the fully burnt fabric temperature cool down slowly towards the room temperature (28.5°C) with the ash formation of whole sample. One another observation is that area under the temperature curve of the control fabric is much higher than the area under the curve of treated fabric. This might be due to the formation of more amount of heat energy in case of control fabric compared to the treated fabric. Therefore it will be very useful for the user in real life situation as the treated fabric generated much less temperature (100°C) and heat energy.













Note: * Mosquitoes were moving just outside the surface of the fabric. However they did not land on the fabric surface.

3.7 Reaction mechanism of cross-linking agent Figure 3.5 shows the cross linking reaction of DMDHEU resin between thio-urea and cellulose. From the Figure 3.5, it is well understood that there are 3 possible chances of reactions. Most possible chance of reaction is represented in 1st reaction mechanism, which shows the reaction of cross-linking agent and cellulose. Here no thiourea was involved into the reaction. Therefore it did not contribute to improvement of fastness properties of thiourea on jute fabric.

The mosquito repellency effect of the treated fabric might be attributed with the strong odors of thio-urea sulphur di oxide, ammonia which was present surrounding the treated fabric surface [23, 24]. One another observation from the table is that within first 60 min some mosquitoes landed on the treated fabric surface. However, later after 1h they fled away. This might be due to the presence of sulphur which is toxic to the mosquitoes [25].

3.6 Mosquito repellency analysis Mosquito repellency test of the control and the treated (B) fabric was carried out by using cage test method and the observed quantitative results were represented in Table 3.4. It evidenced that the thio-urea treatment repel mosquito population. It can be observed from the table that after 1 h, out of 25 mosquitoes in the cage, 10 mosquitoes were present on the control jute fabric whereas only 3 mosquitoes landed on the treated fabric.

FINISHING 3.8 FTIR analysis The FTIR analysis was carried out for both the control (A) , treated jute fabrics (B) and one washed fabric (C) as shown in Figure 3.6.The strong intense IR band was observed at 1600 cm-1 in the treated sample (B). Compared to the control jute fabric (A), this band was more intense in treated fabric (B). It can be attributed to the NH2 stretching vibration [26]. Intensity of this band in curve C is in between A and B. A small peak also has been observed at 1089cm-1 and 1417 cm-1 in B. It can be attributed with the C=S symmetric and C=S asymmetric stretching vibration [19] respectively. The N-H absorption band has been observed at 3100-3400cm-1[27] in sample B.

Figure 3.5 Cross linking reaction of thio-urea with DMDHEU cross-linking agent and cellulose

It can be seen from 2nd reaction mechanism that, crosslinking agent i.e DMDHEU resin holds both, cellulose and also thio-urea. Here it acted as mediator between cellulose and thio-urea and improved the fastness properties. Further, thio-urea can also be attached with the cellulose as shown in 3rd mechanism. Therefore both 2nd and 3rd mechanism supports the phenomena of improved fastness. Apart from it being a lingo cellulosic fibre, jute lignin also takes part into the reaction with thio-urea and resin. It might be due to the unsaturation of lignin and higher coordinating power of sulphur present in thio-urea [11].Thus resin cross-linking agent helped to achieve better fastness properties. We can also observe from the Table 3.2 that with increasing the concentration of resin, thermal properties (LOI and vertical flammability) are improved after washing. It may be attributed to the fact that with the increase in resin concentration, more amount of NH2 groups of thiourea are available for cross linking reaction and thus increases the washing durability. However possibilities of the formation of 2nd and 3rd reactions are comparatively less than the 1st reaction. Therefore the fastness properties of thio-urea with resin is not adequate and detoriated with washing.

Figure 3.6 FTIR spectra of control (A), [thio-urea (80 gpl) + resin (80gpl)] treated (B) and washed fabric (C).

From Figure 3.6 it is observed that N-H band intensity reduced after washing. However the intensity of this band at 3400cm-1 is more than the control sample A. The absorption bands in the range of 1350-1400 cm-1 assigned to the C-N vibrations. Intensity of this band in washed sample C is in between A and B. Therefore, from the IR spectra it is clear that for the resin treated sample partial amount of thio-urea was left after washing on the fabric surface and helped to get more thermally stable fabric than the control fabric. 3.9 Physical properties After thio-urea, resin application 27% yellowness index of the treated jute fabric (B) was increased compared to the control fabric. With the addition of it treated sample turns duller as the brightness index is reduced. Therefore, it can be concluded that the treatment has adverse 280

effect on the colour of the treated fabric. From the Table 3.5 it also can be observed that with increasing the concentration of resin, tensile strength of the treated fabric was reduced. Thus at 80 gpl resin concentration weft tensile strength reduces around 15% compared to the control fabric. It may be attributed with the acidic degradation of the treated jute in curing condition [28].

4. Conclusion The current paper describes the value addition of jute fabric by imparting fire retardancy and mosquito repellency using thio-urea resin formulation. Thio-urea with resin delivered better fastness properties compared to the thio-urea alone. As far as the flammability and the physical properties are concerned, 80 gpl thio-urea + 80gpl resin formulation was found to give best results for application on jute fabric by padding method. Temperature curve showed the thermal stability of the treated fabric, TG curves showed the dehydration and char formation phenomena of the treated cotton fabrics. Further the treated fabric shows good mosquito repellent property. Apart from it application process is very simple and inexpensive as no costly chemicals are needed. Limitation is that this treatment forms toxic gases at high temperature and finish is not much durable to washing. Both thermal stable and mosquito repellent effect enhanced the application potential of the treated fabric in home furnishings, home textiles such as curtains, table lamp, sofa cover etc., where only few washing is required. As the weathering fastness of the treated fabric are moderate to good , treated fabric can also be used as some outdoor non permanent applications like puja pandals, book fair stalls etc. Since thio-urea is abundantly available and application process is simple, the scope of apJan - Feb 2014

Abstract Extracellular pigments were obtained from the fungi Penicillium vinaceum and Rhizopus spp. under optimised fermentation conditions like media, time and temperature. Penicillium vinaceum grown in Czapek Dox Broth (CZB) and Potato Dextrose Broth (PDB) at 28 ± 2°C produced two hues purple and brown respectively. On the other hand, Rhizopus spp. grown in PDB at 15 ± 2°C produced red hue. Highest optical density in both the cases was attained in 17 days in stationary cultures. The supernatant colored liquid was separated from the colorless mycelia and used as dye liquor for dyeing unmordanted silk and wool fabrics at 70°-80°C for about 45 min. Assessment of dyed fabrics in terms of fastness revealed good to excellent wash and rub fastness. Percentage absorption and color value has been estimated to be greater for wool than silk. Result of human toxicity tests showed the safer nature of the dyed fabrics for human usage. The analysis by simple chromatography revealed multicomponent nature of the pigment obtained.

effective protocols. Before extracting the colour from these microbes these are also looked for their safety and efficacy. Some studies have confirmed the non toxicity and biodegradability of the fungal pigments. Microbial cell production offers reliable scalable technology. The advantages of pigment producing microorganisms include independence from weather conditions, easy and fast growth and colours of different shades can be obtained by growing on cheap substrates under controlled conditions [6]. If microbes are cultured in fermentation medium and their growth kinetics are optimized for maximum pigmentation for possible use as textile colorants, they can prove to be 'bioengineered' textile dyes. These can be standardized and subjected to direct experimental control. Thus, they can combine the advantages of both plant based and synthetic dyes. Investigation in production and evaluation of microbial pigment as textile colorants is currently being investigated at the British Textile Technology Group [7-10]. Fungi are ecological interesting source of pigments, as some of these species are rich in stable colorants such as anthraquinone. Anthraquinones are secondary metabolites produced from fungi that can be used as textile colorant. A number of anthraquinone derivatives have been identified from various species of fungi and lichens. These metabolites are of interest because many of them possess significant antibiotic activity, primarily against Gram-positive bacteria and Pseudomonas aeruginosa. Anthraquinones are

1. Introduction The dyestuff industry is suffering from increase in costs of feedstock and energy for dye synthesis, and is under increasing pressure to minimize the damage to the environment. The industries are continuously looking for cheaper, more eco-benign routes to existing dyes [1]. Natural dyes are eco-friendly for the environment as compared to the synthetic dyestuff that can exhibit better biodegradability and generally have a higher compatibility with the environment [2-3]. Natural dyes can be obtained from vegetable sources like roots, stems, leaves, flowers and fruits of various plants or can be obtained from animal sources like dried bodies of certain insects, shellfish, cochineal, lac etc. as well as from certain microorganisms [4]. It is a well known practice to extract the natural colors from the plant sources but the yield is very low and they have low eco-efficiency [5]. Therefore, there is an emerging need for searching for new sources apart from these plant based natural dyes. Extraction of colours from the microbial source is an upcoming field. Various microorganisms like bacteria, fungi, yeasts and algae are coloured and natural colours can be extracted from these sources using simple and * All correspondence should be addressed to, Sudha, Department of Fabric & Apparel Science, Institute of Home Economics, University of Delhi, Hauz khas, Delhi 282

BIOTECHNOLOGY also reported to have antiprotozoal and cytotoxic activities [11-13]. In view of these aspects, the present study involved the isolation of pigment producing fungi; optimize their colour production and check in the dyeing ability of different fabrics with these colorants. Further dyed fabrics were assessed for colour fastness and toxicity.

colored culture filtrate (supernatant) was used as dye liquor. 2.3. Materials for dyeing For dyeing purpose desized and scoured 100% cotton, silk and wool having thread count 130, 234 and 117 respectively were used. Metallic mordants like alum, copper sulphate and ferrous sulphate of analytical grade were used for silk and wool, whereas, Harad (Myrobalan) was used for cotton. The percentages of mordants taken were on the weight of the fabric (o.w.f) as 5%, 10% and 20% and the method used for mordanting was pre-mordanting at a MLR 1:30 at 60°C for 30 min.

2. Materials and Methods 2.1. Fungal Isolates Pigment producing fungi were isolated from air and soil of nearby locality using PDA (Potato Dextrose Agar) plates (extract of 300 g peeled potato, 2.5 g glucose, 15 g agar in 1000 ml distilled water). For isolation of fungi from air, PDA plates were exposed in air for 5 mins at different areas within the college. For soil, samples were collected randomly and 1 g of each was dissolved in 10 ml of sterile distilled water in a test tube. Then 0.1 ml of soil solution was spread onto the PDA plates with the help of sterile spreader. All PDA plates were kept in B.O.D incubator at 28ºC±2ºC for 3-4 days. Different fungal colonies appeared on PDA plates from which pure cultures of the pigment producing fungi were obtained by transferring them onto fresh PDA plates and incubating at 28ºC±2ºC for 3-4 days. After screening one member of samples color producing species was Rhizopus spp. obtained from soil. Another fungal sample i.e. Penicillium vinaceum used in the study was sourced from Division of Plant Pathology, Indian Agricultural Research Institute, New Delhi, India.

2.4. Dyeing Before dyeing pH of the supernatant was checked and then 50 ml of each of the colored culture filtrate (supernatant) was used to dye 1g unmordanted and mordanted silk, wool and cotton samples at 70°-80° for 45 min. The dyed samples underwent sequential treatments: rinsing with cold water, washing in a bath containing 3 g/l nonionic detergent at a material/liquor ratio of 1:30 at ambient temperature for 5 min, a second rinsing with cold water, and drying in air.

2.2. Pigment production For color production, mycelia disk (5mm diameter) from pure cultures of Rhizopus spp. and Penicillium vinaceum was taken from PDA plates and inoculated individually in different culture media viz. Potato Dextrose Broth (PDB), Czapek Dox Broth (CZB) and Minimal Media Broth (MMB). Incubation was done for 3 weeks at different temperatures i.e. 15°C, 28°C and 37°C to standardise the optimum temperature. Incubation was also done both under stationary and shaking conditions to maximise the color production.

2.5.2. Color measurement Color strength (K/S), L*, a* and b* values were calculated using Computer color matching system (Macbeth3100, Premier colour scan Instruments Pvt. Ltd., Samata Nagar, Thane).

After about 3 weeks of incubation fungal cultures showing color were filtered out using nylon mesh. Further to extract color, fungal mycelia separated out from supernatant liquid were crushed using the Homogeniser (Remi Motors). Crushed mycelia was then divided into 2 parts and to each part 10 ml of methanol and 10 ml of chloroform was added and stirred using Magnetic stirrer (Remi Motors). As no colorant was extracted from the mycelia of two fungi after homogenisation it was discarded. Only Jan - Feb 2014

2.5.3. Color fastness The dyed fabrics were evaluated for color fastness to rubbing (crockMETER-1™ ISO 9001:2000 group, Paramount Instruments Pvt. Ltd., India) and colour fastness to washing using (digiWASH-INX™ ISO 9001: Certified group, Paramount Instruments Pvt. Ltd., India).

2.5. Analysis of dyed fabrics 2.5.1. Percentage absorbance A Scanning Minispec SL 177 (ELICO) Spectrophotometer was used to calculate the Percentage absorbance of the dyed fabrics using equation (1): O.D b - O.D a % absorption = × 100 .....(1) O.D b Where O.D b represents Optical density of the dye liquor before dyeing and O.D a represents Optical density of the dye liquor after dyeing.

BIOTECHNOLOGY 2.5.4. Toxicity test To find out the possible toxicity of the fungal colorant on the human skin a simple patch test was done. In this test, a swatch of 1Ă—1 inch of dyed samples was fixed on the arm of around 30 subjects for about 48 hours and during this time bathing and swimming was refrained. This was done to check for signs of rashes, swelling or any other form of skin allergy.

Penicillium vinaceum and Rhizopus spp. for attaining the maximum pigmentation. 3.2. Dyeing Before dyeing, pH of the colored culture filtrate was also tested to see a change in pH. As quoted by some researchers fungus growing in the medium and the medium itself can alter its pH [14]. The pH of the culture filtrate obtained from Penicillium vinaceum both in CZB and PDB at 280C was neutral i.e. 7. Whereas it was acidic i.e. 3 for Rhizopus spp. grown in PDB at 15°C. On dyeing, only silk and wool were dyed and cotton did not stain at all even when pH of the

2.6. Analysis of colorant via paper chromatography A simple paper chromatography was carried out for separation of pigments with the help of different solvents like: Water, Chloroform: Methanol: Acetic acid: Distilled water (25:15:4:2) and Butanol: Acetic acid: Distilled water (60:15:25). Chromatography columns were prepared using these three compositions and in each column a chromatography paper was set having concentrated dried spots of the colorants created with the help of capillary tubes. Columns were then left untouched till solvent ascended and various components separated out as spots or zones. After separation retention factor (Rf) value was calculated for the separated components. 3. Results and discussions 3.1. Fungal Pigments Two fungi namely Penicillium vinaceum and Rhizopus spp. were grown in different media to produce the pigments. It was found that color produced by both the fungi was extracellular. As no or little color production was obtained after use of MMB (minimal media broth), shaking incubation conditions and homogenisation extraction from fungal mycelia; these were not used further in the study. Penicillium vinaceum produced maximum pigmentation both in CZB and PDB at 370C but results of pigmentation were not consistent on repeating the experiment at this temperature. Hence 280C was considered the optimum temperature for maximum pigmentation and was used for further experimentation. At 370C Penicillium vinaceum produced two hues purple and brown in CZB and PDB respectively. Rhizopus spp. grown in PDA at 150C produced red hue. The incubation time for both the fungi was selected by analysing the optical density (O.D) of culture filtrate incubated for different time intervals at lmax 650 nm using Spectrophotometer.

Figure 3.1: Readings of optical density (O.D) recorded for Penicillium vinaceum over an incubation period of 21 days

Figure 3.2: Readings of optical density (O.D) recorded for Rhizopus spp. over an incubation period of 21 days

Highest optical density in culture filtrate of both the fungi was attained within 17 days after which the value of optical density remained same as shown in Figure 3.1 and 3.2. Hence, an incubation period of 17 days was chosen as best time period for growth of the fungi viz

colored liquor was made neutral. Unmordanted samples of silk and wool were successfully dyed in hues of purple, brown and red respectively. Whereas, mordanting with metallic mordants produced duller shades. This may be 284

because of the colorant itself, as it is assumed to have some proteolytic enzymes that aid in dyeing protein fibers. There may be a possibility that the complexes of metallic mordants hinder the action of enzymes present in the colorant and the resultant dyeing is not proper.

3.3.2. Colour measurement Table 3.3 and 3.4 summarises K/S, L*, a* and b* values of wool and silk using computer colour matching system. From the table it is clear that wool has higher K/S value in all the cases than silk. This indicates that the colour produced on wool is intense and bright than silk.

3.3. Analysis of dyed fabrics 3.3.1. Percentage Absorption The optical density of all the culture filtrate before and after dyeing was recorded and used to calculate percentage absorption for wool and silk fabric as per Table 3.1 and 3.2.

3.3.3. Color fastness As per ratings of standard SDC Grey scale: BS 1006 the dyed samples exhibited good to excellent rub and wash fastness properties. It is evident from Table 3.5 and 3.6 that fastness to wash is excellent for all the samples. Whereas, rub fastness to dry and wet rubbing showed varied results i.e. for dry rubbing Penicillium vinaceum samples fastness was recorded as 4/5

As evident from Table 3.1 and 3.2 the percentage absorption of colorant is more in wool than silk. This is because wool has more amino acids and higher amorphous areas than silk. Absorbency of wool is greater than that of silk [15]. It was also found that percentage absorption of wool is more for colorant obtained from Rhizopus than obtained from Penicillium vinaceum. It is because pH of Rhizopus spp. was 3 (more acidic) whereas for Penicillium vinaceum it was 7 (neutral). The wool fibre contains equal amount of amino and carboxyl groups which ionize and Table 3.2: Percentage absorption of silk and wool dyed with Rhizopus spp.

For wet rubbing Penicillium vinaceum samples fastness was ranged from 3/4 to 4 i.e. considerable to less staining which means good wet rub fastness and for Rhizopus spp. samples it varied from 4/5 to 5 i.e. very less staining to no staining which means very good to excellent wet rub fastness.

3.3.4 Toxicity test Results of toxicity tests of both silk and wool sample showed no signs of red marks, swelling, rashes, itching and irritation or any other form of skin allergy. This indicates that the fungal colorant used to dye silk and wool in the study is safer to use and nontoxic to human skin. 3.3.5 Analysis of colorant via paper chromatography Out of the three compositions used, only water composition revealed that the dye is multicomponent as it is showing range of colors or color zones on the chromatograph having different Rf values. Spot-A of Rhizopus spp. (PDB, 150C) had just a single color component (orangish brown) at a Rf value 0.885 whereas, Spot-B and C of Pencillium vinaceum in PDB and CZB had two color components (orange and brown) at a Rf value 0.596 and 0.783 and three components (pink, red and brown) at a Rf 0.42, 0.570 and 0.774 respectively.

4. Conclusion Textile bio-colorants were efficiently extracted from two fungi namely Penicillium vinaceum and Rhizopus spp. The colorants obtained were extracellular and no intracellular pigment was extracted from both the fungi. Further, it was found that physico-chemical growth conditions of the fungi can be controlled and optimized to get maximum pigmentation. Penicillium vinaceum grown in CZB and PDB at 280C produced two hues purple and brown respectively. On the other hand, Rhizopus spp. grown in PDA at 150C produced red hue. For both the fungi the highest optical density was observed within 17 days of incubation in stationary cultures after which no further change in colorant was seen. After extraction of optimized colorants dyeing of silk and wool samples, with and without mordanting was carried out. Mordanting seems to have no significant effect on the dyeing performance as its inability to produce different hues and hence was eliminated from the study. Without mordanting samples of silk and wool were successfully dyed into bright shades of purple, brown and red corresponding to it supernatant colors at 700-800C for

about 45 min. Dyed samples were then subjected to spectrophotometer analysis to calculate the percentage absorption and color value of the dyed samples and have been estimated to be greater for wool than silk. Fastness tests like rub and wash fastness revealed good to excellent fastness of the dyed samples. Moreover, toxicity test of pigments was found to have no effect on human skin and is safer to use. Analysis of pigments by paper chromatography revealed that the colored culture filtrate of Penicillium vinaceum is multi component, whereas, that of Rhizopus spp. is a single color component. Ultimately, this can be concluded that fungal sources can be exploited for color production for using as a textile dye under controlled experimentation either in a small setup or on a mass scale basis in an eco friendly manner on wide variety of substrates.

Application of Multi-Criteria Decision Making (MCDM) Technique for the Selection of Vegetable Dyes Prabir Kumar Choudhuri* Visva Bharati, Textile Section, Dept. of Silpa Sadana, Sriniketan. Abstract Multi-criteria decision making technique is a branch of operation research (OR), now popularly applied in the field of engineering, banking, fixing policy matters etc. It can also be applied for taking decisions in daily life like selecting a car to purchase, selecting bride or groom and many others. Various MCDM methods namely Weighted sum model (WSM), Weighted product model (WPM), Analytic Hierarchy Process (AHP), Technique for Order Preference by Similarity to Ideal Solutions (TOPSIS) and Elimination and Choice Translating Reality (ELECTRE) are there to solve many decision making problems, each having its own limitations. However it is very difficult to decide which MCDM method is the best. MCDM methods are prospective quantitative approaches for solving decision problems involving finite number of alternatives and criteria. So the MCDM technique provides enough scope to be applied for the selection of vegetable dyes or ranking the dyes among them on the basis of some selection criteria. The present paper is an attempt to explore the scope of applying the AHP method of multi-criteria decision making technique to determine the quality values of the vegetable dyes under consideration on the basis of some important criteria like Fastness properties, cost & polygenetic properties and to select or rank them accordingly. Keywords MCDM, Analytic Hierarchy Process (AHP), Vegetable dye, Quality values.

2. Overview of MCDM and AHP Multiple criteria decision making (MCDM) is a very popular discipline of Operation Research (OR), having relatively short history of about 40 years. Its development has accelerated with the rapid development of computer technology. Computer programming has helped to handle huge data related to criteria, sub-criteria and alternatives, their systematic analysis to tackle MCDM problems, complex in nature. This has made MCDM extremely important and useful tools in solving business decision making problems.

Journal of the TEXTILE Association

1. Introduction Multiple criteria decision making (MCDM) refers to making decisions in the presence of multiple, usually conflicting, criteria. MCDM problems are common in everyday life. In personal context, a house or a car one buys may be characterized in terms of price, size, style, safety, comfort, etc. MCDM techniques are very much applicable for selecting students to provide scholarships. In business context, MCDM problems are more complicated and deal with many criteria and sub-criteria to arrive at a decision among many alternatives. Clear understanding on the subject can explore newer fields for its application to make decisions.

There are many methods available which have enjoyed a wide acceptance in the academic area and many realworld applications. Each of these methods has its own characteristics and background logic. The Weighted sum model (WSM), Weighted product model (WPM), Analytic Hierarchy Process (AHP), Technique for Order Preference by Similarity to Ideal Solutions (TOPSIS) and Elimination and Choice Translating Reality (ELECTRE) are among the most popular ones. Each has some advantages and disadvantages. User has to choose the suitable method according to complexity of the problems. So, it is very difficult to say which one is the best MCDM method.

Although the selection of vegetable dyes can be made on the basis of experience or some other ways, MCDM technique are yet to find its place for its quality evaluation in more scientific manner. This paper deals with the exploration of possibilities of applying AHP method of MCDM technique for selection of vegetable dye among finite alternatives based on finite number of decision criteria. * All correspondence should be addressed to, Dr. Prabir Kumar Choudhuri Visva Bharati (A Central University), Textile section, Dept. of Silpa Sadana, Sriniketan - 731236.

TESTING The Analytic Hierarchy Process (or AHP) method was developed by Professor Thomas Saaty [1-4]. This is one of the frequently discussed methods of decision-making. The reason of its popularity lies in the fact that it can handle the objective as well as subjective factors [5] and the criteria weights and alternative scores are elicited through the formation of a comparison pair-wise matrix which is the heart of the AHP. Since the introduction of AHP, it has evolved into several different variants like revised AHP proposed by Belton and Gear in 1983 [6] and multiplicative AHP proposed by Barzilai and Lootsma in 1994 [7]. These methods have been widely used to solve a broad range of multi-criteria decision problems.

The normalized weight of the i-th criteria (wi ) is determined by calculating the geometric mean of the i-th row (GMi ) of the above matrix and then normalizing the geometric mean of rows. This can be represented as follows: 1

GMi = {Unj=1cij}n and wi =

The principal eigen vector lmax of the above matrix of the original pair-wise comparison matrix C1 is calculated. To check the consistency in pair-wise comparison judgment, consistency index C1 and consistency ratio CR are calculated by following equations:

2.1. AHP Methodology AHP decomposes a complex MCDM problem into a system of hierarchy. The final step in AHP deals with the structure of a m 4 n matrix. The matrix is constructed by using the relative importance of alternatives in terms of each criterion. The process of working out the problem starts with the formation of a decision hierarchy where the hierarchy of the problem is formed by keeping the overall objective or goal at the top and the alternatives at the bottom. Relevant attributes of the decision problem such as criteria and sub-criteria are placed at the intermediate levels. Next, the pair-wise comparison matrix is formed, in this step the relative importance of different criteria with respect to the objective of the problem is determined by using the AHP. For doing this, a pair wise comparison matrix of criteria is constructed using a scale of relative importance proposed by Saaty which is shown in Table 2.1. The judgments are entered by using that fundamental scale of AHP. In AHP the number of pair-wise comparisons in a decision problem having alternatives and criteria is expressed by the equation; n(n-1) m(m-1) +n 2 2 For criteria, the matrix will be m 4 n order. The entry cij will denote the comparative importance of i criteria with respect to j criteria. In the matrix cij = 1 when i = j and cji = 1 c ji The pair-wise comparison matrix c1 is shown as,c1 =

and, CR =


Where, RCI = random consistency index and its value can be obtained from table 2.2. If the value of CR is 0.1 or less, then the judgment is considered to be consistent and therefore acceptable. Otherwise the decision maker has to reconsider the entries of pair-wise comparison matrix.

Journal of the TEXTILE Association

In order to calculate the relative importance of sub criteria with respect to corresponding criteria, the pair-wise comparison between the attributes of sub-criteria are made in the same way as discussed earlier. The global weights of sub-criteria are calculated by multiplying the relative weight of sub-criteria with respect to the corresponding criterion and the relative weight of criterion with respect to the objective.

lar MCDM approaches namely, technique for order preference by similarity to ideal solutions (TOPSIS) and analytic hierarchy process (AHP). Ranking of navels was elicited in accordance with the relative closeness value determined by TOPSIS method. For the determination of technological value of cotton fibre Majumdar A et al. [5] have used Multi-criteria decision- making approach and compared its efficacy with existing approach. The MCDM approach was found to give better correlation between fibre quality and yarn strength. Hybrid AHPTOPSIS method of Multi-criteria decision-making was also found to be effective as shown by Majumdar et al. [9] in their study for ranking the cotton fibres which gave good agreement with the ranking of yarn in terms of tenacity. 4. Application of Multiplicative AHP in selection of vegetable dyes 4.1. Hierarchy formulation The goal or objective of the present investigation is to determine the acceptance value of vegetable dyes which should reflect the achievable level of Fastness properties, cost and polygenetic properties. So, the dye properties criteria of this problem can be classified under three headings, namely fastness properties, cost and polygenetic properties. Fastness properties can be divided into three sub-criteria, washing fastness (WF), rubbing fastness (RF) and light fastness (LF) whereas cost criteria and polygenetic properties are solely represented by raw material cost (RMC ) and no. of available shades (NAS) respectively.

Two activities con tribute equally to the objective.

If activity p has one of the above numbers assigned to it when compared with activ ity q, then q has the reciprocal value when compared with p

After obtaining the global weights of each attributes, the priority index is calculated according to the variant of AHP followed. Finally the ranking of the alternatives are made on the basis of index obtained Table 2.2: RCI values of different number of alternatives

TESTING At the lowest level of the hierarchy, there are the different alternatives of dye types namely A, B, C, D, ……, N which should be ranked according to their acceptance value. The schematic representation of the problem is depicted in Figure 4.1. 4.2. Determination of criteria weights and rankings of alternatives With respect of the objective of the problem, the pairwise comparison matrix of three criteria is given in Table 4.1. Here the comparison is made according to Saaty's scale given in Table 2.1.

In order to calculate the relative weights of sub criteria with respect to corresponding criteria, the pair-wise comparison between sub-criteria of fastness properties and the derived weight vectors are shown in Table 4.2 Then the global weights of sub-criteria are calculated by multiplying the relative weight of sub-criteria with respect to the corresponding criterion and the relative weight of criterion with respect to the objective. Hence, the global weight of washing fastness is 0.538×0.731=0.393, the global weight of rubbing fastness is 0.164×0.731=0.119, and the global weight of light fastness is 0.298×0.731=0.218.

Table 4.1: Pair-wise comparison matrix of criteria with respect to objective

The global weight of cost parameter and polygenic properties are 0.081 and 0.188 respectively.

Rubbing fastness

It can be inferred from Table 4.1 that fastness properties very strongly predominate over the cost parameter and essentially predominate over polygenetic properties whereas the dominance of polygenetic properties over cost parameter is moderate. The normalized column of table 3 indicates that the fastness properties of dye have the most dominant influence with a relative weight of 0.730. The relative weights of cost and polygenetic properties are 0.080 and 0.188 respectively. For the measurement of consistency of judgment, the original matrix is multiplied by the weight vector to obtain the product as shown below, 1 7 5 0.731 2.230 1/7 1 1/3 ✕ 0.081 = 0.247 1/5 3 1 0.188 0.574


Therefore, according to the multiplicative AHP model, the equation to calculate the acceptance value of yarns (MIAHP) becomes; MIAHP =

values of MIAHP for A, B, C, D, .… N type of vegetable dyes can be calculated on the basis of actual values of parameters against corresponding dye type. The dye having highest MIAHP value will rank top and is most acceptable. The descending order in the values will be the ranking of dyes on priority.

The consistency in the pair-wise judgment is found to be justified as confirmed from calculating the consistency index (CI) and consistency ratio (CR) putting the value of random consistency index (RCI) against corresponding number of alternatives from table 2.2. Therefore, 3.065-3 CI 0.0325 = 0.0325 & CR = = 3-1 RCI 0.58 (acceptable)


CR = 0.012

5. Conclusions It can be concluded that the selection of natural dyes can effectively be made using multiplicative AHP technique very well. In the prevailing practice the selection of dyes are often made based on either quality characteristics or cost factor which does not reflect the quality - cost optimization. But the present methodology can effectively help to select dyes according to their rank

Enterprise Social Responsibility: A Pledge for Knitwear Industry of Ludhiana 1

Prabhjot Kaur*1 & Navjot Kaur*2 Department of Clothing and Textiles, Government Home Science College, 2 Continental Group of Institute, Jalvehra (Fatehgarh Sahib).

Abstract Enterprise Social Responsibility (ESR) is not a fad or a passing trend, it is a business imperative that many Indian companies had begun to think about or are engaging with in one way or another. This study was undertaken to comparatively analyze the commitment of knitwear units towards social practices among inward oriented and outward oriented units of Ludhiana. Eighty industrial knitwear units belonging to Knitwear Apparel cluster of Ludhiana (Punjab) were surveyed. Random sampling method (Lottery method) was used for the selection of 80 units from 4 major area blocks in Ludhiana. Interview Questionnaire schedule was used to collect the data regarding their ESR practices. The results revealed that Enterprise Social Responsibility had become increasingly important because of the today's heightened interest in the proper role of business in society. Majority of units believed that profit motive and social responsibility are contradictory to each other. Most of the Outward oriented units were more committed towards social practices and were involved in one or the other social betterment practices in comparison to inward oriented units. Inspite of being involved in community betterment work, most of the units did not publicize their social activities among common people.

in the press in regard to outsourcing by developed countries of low-tech, labor intensive production for developing countries. Not only Consumer organizations increasingly demand information about production conditions and routes to market but also Non Governmental Organizations (NGOs) and various trade unions approach companies with requests and demands regarding their commitment to the society. Social responsibility is the combined effort by mankind to make this world a safer, more nurturing, and caring place [1]. Although the implementation of social responsible activities involves time, effort and resources, yet the industry owners have realized that it is very important nowadays as it not only improves both the public image of the company and productivity, increases employees satisfaction from their work but also paves the way for more innovation and market flexibility, and hence ultimately the brand gains in value. The perception of the apparel firm improves among its stakeholders, i.e. clients, suppliers, retail chains, public authorities, and stock market investors, all of whom work more willingly with the company and/ or use its services. Hence, CSR activities are now being undertaken throughout the globe. The 1950's saw the start of the modern era of CSR when it was more commonly known as responsibility.

1. Introduction "Business is not separate from societyâ&#x20AC;Ś. Companies are not only engines of economic growth but also pivotal agents of social and political integration" Fombrun [4] Social compliance is a burning issue in the challenging world market now days. It has become one of the key business trends of the past decade. Prominent buyers from developed countries are increasingly emphasizing on compliance of standards as their consumers are much more concerned about this issue. Almost every Fortune 100 company now makes meaningful charitable contributions each year. Moreover, a new consciousness concerning 3Fs (Fair Price, Fair Say, Fair Share) and 4Cs (Produce clean, Eat clean, Wear clean, Live clean) has arisen in the 'developed' world. So Social Responsibility has become an issue of increasing importance and is taking up more and more space * All correspondence should be addressed to, Mrs. Prabhjot Kaur Department of Clothing and Textiles Government Home Science College Sector-10, Chandigarh(UT) Email : Jan - Feb 2014

MANAGMENT company has on people-even indirectly. This includes the people within the company; in the supply chain of the company, as well as customers of the company.

In 1953, Howard Bowen published his book, 'Social Responsibility of the Business', and he is largely credited with coining the phrase Corporate Social Responsibility and is perhaps the father of modern CSR. Bowen advocates that CSR was "industry's obligation to pursue those policies, to make those decisions or to follow those lines of actions which are desirable in term of objective and values of society" [2].

1.1. The social aspect of CSR for an organization Corporation owes a responsibility to society that goes beyond mere production of goods and services. Every corporate or business entity not only has a responsibility to add to the problems of the society but help to solve social problems.

The entirety of CSR can be discerned from the three words phrase: Corporate, Social, and Responsibility.CSR covers the relationship between corporations and the society with which they interact.CSR also includes the responsibilities that are inherent on both sides of these relationships.CSR defines the society in its widest sense and on many levels, to include all the stakeholder and the constituent groups that maintain an ongoing interest in the organization's operations [6].

1.1.1. Responsibility towards Owners Every business should provide fair return on capital, maintain safety of investment and disclose material information about business and market. 1.1.2. Responsibility towards customers Every business should provide goods and services required to fulfill wants, quality goods and services, produce and supply harmful goods, charge reasonable price and remain fair in dealings.

CSR is the recognition on the part of management of an obligation to the society. It serves not only for maximum economic performance, but also for humane and constructive social policies as well. It can be thought of in terms of "good neighborliness". The concept involves two phases. On the one hand, it means not doing things that spoils the neighborhood. On the other, it may be expressed as the voluntary assumption of the obligation to help solve neighborhood problems. Neighborliness may be substituted with the term social responsibility implying the commitment of a business or Business in general, to an active role in the solution of broad social problems, such as racial discrimination, pollution, transportation, or urban decay [3].

1.1.3. Responsibility towards employees A Business has a responsibility to provide them with fair and competitive wages, good working conditions, proper safety measures to avoid health and life hazards, training and prospects for growth and development and no discrimination between different employees on the basis of caste and colour. 1.1.4. Responsibility towards local community Business has a responsibility of not polluting the immediate environment, not to dump waste around, aid the community with health care facilities and education and improve surrounding infrastructure [5] 1.2.

MANAGMENT selected for the study was the individual knitwear unit in Ludhiana which was a member of Knitwear club. Knitwear club has membership of 800 Knitwear units. Treating this as a proxy for the population, 80 medium knitwear units (10% of the population) were selected which were considered adequate and manageable to obtain the required data. Sample area was divided in four regions i.e. Area I, II, III & IV. Twenty units were randomly selected from each area. The information regarding the industrial unit's social commitment was collected personally by the researcher through personal interview of the unit owners or their representatives after taking telephonic appointment. The data collected was coded, tabulated and analysed.

In Ludhiana, 69% of units believed that profit motive and social responsibility were contradictory to each other. This shows their thinking in context to CSR that it is more of financial liability for the units.

Figure 3.2: Column diagram showing respondents on the basis of engagement in social responsible activities

Forty four percent knitwear units were following social responsible occasional activities related to business strategy as compared to 26% units which did not support CSR activities. Majority of the outward oriented units were more regular in relation to social responsible activities as compared to inward oriented units. This was mainly because of the periodical factory audits conducted by the international buyers to check the social compliance. Figure 2.1: Area Distribution of Ludhiana

3. Results & discussion The results of the survey conducted to study the awareness and commitment of 80 knitwear units towards social practices in Ludhiana is given below.In Ludhiana, out of 80 knitwear units surveyed, 89% of units were garment manufacturing, 9% of units were composite (Knitting, having sewing & processing facility under one roof), and 2% of units were of fabricating.

MANAGMENT disposal of waste (chemicals, fabric scrap, paper polluted water etc). Only few units organized recreational events, partnership projects of social solidarity, conservation of local heritage and conducted cause related marketing campaign. Majority of the outward oriented units gave charities to less fortunate & needy people in the society. They conducted group marriages of poor girls in gurdwaras and also provided them financial assistance through NGO's , industrial training along with jobs, carried out educative activities like appointing teacher to teach very poor students free of cost, recruit disabled or handicapped people in administered work etc in comparison to inward oriented units.

Forty one percent of units were donating money to hospitals for treating poor & old people, while only few (19%) organized free medical camps for the local community. All the outward oriented units were engaged in one or the other medical related activities like blood donation, eye treatment camps, awareness lectures on chewing tobacco, cigarette smoking, drugs, HIV aids etc while only 29% inward oriented units were involved in such activities.

Figure 3.6: Column diagram showing respondents on the basis of the educative initiatives for the community

Majority of units were involved in educative initiatives like providing donation to schools, training centers for sports facilities, and scholarships to poor students and free education to the children. Almost all the outward oriented units were involved in providing educational facilities for the community like appointing teachers to teach poor students free of cost, donate money in the schools and colleges through NGO's, provide special industrial training in comparison to only 33% inward oriented units.

'Branded or Non Branded Garments?' A Study on Consumers Preference M. D. Teli*, Sanket P. Valia, & Shruti Venkatram Department of Fibres and Textile Processing Technology, Institute of Chemical Technology. Abstract A survey aimed at gaining an insight into the clothing habits in the age group of 18 to 50 was carried out and a total of 60 persons responded to the questionnaire. The said set of people were questioned on their choice of clothes; branded or non-branded, their reason for choosing the same as well as their knowledge and opinions on the environmental aspects of the manufacturing of the apparels they purchased and subsequently used. The survey was divided into a number of sub-parts, one focusing on people's preference i.e. branded or non-branded clothes and the other sub-parts which focused on the purchasing details of specific apparels viz. jeans, t-shirts and the last sub-part entailing the environmental aspects of the manufacturing process of the apparels. The study indicates clear preference of purchasing branded apparels. The inner desire of the customers to encourage ecofriendly processing is also revealed in this work.

Each producer of goods and services attempts to obtain a share of the market potential by making consumers believe that they have the answer to all their personal needs and desires [1]. Brand is the "name, term, design, symbol, or any other feature that identifies one seller's product distinct from those of other sellers"[2].

the brand and is known as the brand experience. The brand experience is a brand's action perceived by a person. The psychological aspect, sometimes referred to as the brand image, is a symbolic construct created within the minds of people, consisting of all the information and expectations associated with a product, service or the company providing them. People engaged in branding seek to develop or align the expectations behind the brand experience, creating the impression that a brand associated with a product or service has certain qualities or characteristics that make it special or unique.

Proper branding can result in higher sales of not only one product, but many other products associated with that brand. Brand is the personality that identifies a product, service or company (name, term, sign, symbol, or design, or combination of them) and how it relates to key constituencies: customers, staff, partners, investors etc.

Brand awareness refers to customers' ability to recall and recognize the brand under different conditions and link to the brand name, logo, and jingles and so on to certain associations in memory. It consists of both brand recognition and brand recall. Brand awareness is of critical importance since customers will not consider your brand if they are not aware of it [3].

Some people distinguish the psychological aspect, the brand associate with like thoughts, feelings, perceptions, images, experiences, beliefs, attitudes, and so on that become linked to the brand. The experiential aspect of brand consists of the sum of all points of contact with

A new piece of research confirms what many, not least in the marketing departments of fashion houses, will long have suspected: that it is not the design itself that counts, but the label.

OTHERS sity in the Netherlands examined people's reactions to experimental stooges who were wearing clothes made by Lacoste and Tommy Hilfiger, two well-known brands that sell what they are pleased to refer to as designer clothing. The two researchers showed in this paper that such clothes did bring the benefits promised: co-operation from others, job recommendations and even the ability to collect more money when soliciting for charity. But this was possible only when the origin of the clothes in question was quite obvious. This study confirms a wider phenomenon. A value of work of art, for example, can change radically, depending on who is believed to have created it, even though the artwork itself is unchanged. And people will willingly buy counterfeit goods, knowing they are knock-offs, if they bear the right label. What is interesting is that the label is so persuasive. But humans often fail to see beyond the superficial. For humans, then, the status-assessment mechanism is going wrong [5].

Figure 3.2: The places where the respondents generally shop for clothes

As shown in Figure 2, votes were received in favor of purchasing clothes from malls. However of 28% votes were received for hawkers. Only 5 respondents purchased clothes from online stores probably due to the inability of a shopper to determine the fitting of garments online.

2. Methodology In the present survey in all 60 people participated, 45% (27) male and 55% (33) female. Within that too, 42% (25) were students and non earners; 32% (19) earned more than Rs 5 lakhs/annum, 18% (11) earned between Rs 1 lakh to 5 lakhs/annum and 8% (5) earned below 1 lakh/annum. 3. Results and Discussion Responding to the questions with regard to their preference for clothing, the response is shown in Figure 1. The total responses or votes are same time more than the number of respondents was only because some respondents chose to give more than one choices.

Quality topped their preference drive, whereas value for money followed by fashion trends was next parameter for taking purchase decision.

OTHERS 3.1. With reference to branded clothes only The names of any 2 brands that is frequently used by the respondents,

A total of 52 out of 108 votes were given for the superior quality of branded goods. 20% voted for consistency in quality of the brand in terms of design, quality etc. The uniqueness and rarity of a brand was the 3rd most preferred reason for buying branded clothes because of the exclusivity it offers.

Some popular brands stated by the respondents were VERO MODA, ZARA, ALLEN SOLLY and MANGO. What was the reason they first bought branded clothes? Most respondents said that GOOD WORD OF (to) MOUTH REVIEWS was the reason they first purchased branded clothes. Interesting add campaigns in newspapers, magazines, on T.V., films etc did not contribute much to their reasons for purchase.

Figure 3.7: With reference to QUALITY of branded clothes only, what parameters do they look for in the clothes they purchase?

Parameters noted in terms of quality while purchasing branded clothes. The questionnaire was put to the respondents to tick all the options of their choice for the above questions. Total 51 out of 60 respondents purchased branded clothes for comfort and fitting that they offered. A close second was the superior quality of the fabric and the feel of the fabric which was followed by the exclusivity of the branded fabric in terms of design and color.

Figure 3.5: Duration of using clothes.

About 30% respondents constituting the majority said that they wore the branded clothes till they were worn out. More than 2 years was a close second for the above question.

Do they buy branded clothes on discount only? This question was aimed to find out whether the respondents purchased branded clothes at a discounted price in order to reap the social appreciation a brand demanded without having to pay the full price. However, only 18 out of 60 respondents i.e. around 30% of the respondents purchased branded clothes on discounted prices. This corresponds with the earlier inferences drawn that where majority of the respondents purchased clothes for its quality over value for money.

What do they do with the branded clothes which they wear no more? Most respondents said that they donated these clothes away to charity. 3.2. With Reference to Jeans only The names of any 2 brands that they frequently use, Some popular brands stated by the respondents were LEVIS', PEPE, LEE, WRANGLER and SPYKAR.

OTHERS The questionnaire asked the respondents to tick all the options of their choice for the above question. A majority consisting of 39 people out of 60 respondents said they preferred foreign branded jeans. Indian branded and both, branded and non-branded came as the second most preferred choice. Responding to the question about the amount spent on a pair of jeans, 83% of the respondents purchased jeans worth Rs 1000-5000 INR range. Where do they purchase their jeans from? A total of 51 out of 60 respondents purchased their jeans from malls. Exclusive brand outlets (24) were a second close choice for purchasing jeans. They used (47% of them) their pair of jeans till it was worn out.

Figure 3.10: Preferred fabric type used to make their Tshirt

The preference of fabric for T-shirt was invariably cotton and then followed polyester/cotton.

Responding to as to why do they choose to buy a pair of jeans, 52 out of 60 respondents, purchased a pair of jeans for the superior quality it offered, followed by the consistency of a brand in terms of its design, comfort, feel etc.

Responding to the amount spent on single T-shirt 70% of the respondents purchase and use T-shirts worth between INR 300-1,000 and 80% of respondents buy them from malls and half of them prefer to buy from exclusive brand outlets in malls. Responding to the question of how long do they use a Tshirt, 49% of the total demographic responded that they did not wear T-shirts for more than 1 year. Their response to what makes them buy T-shirts from particular brand, indicated that 80% of them purchased T-shirt for the superior quality and consistency of a brand in terms of maintain the design, comfort, feel of the T-shirts.

Within Quality 55 out of 60 respondents purchased a pair of jeans for the comfort and the fit it offered. Quality of the fabric and the design and colour of the fabric came as the 2nd most preferred qualitative reason for purchasing a pair of jeans. 3.3. With Reference to T-shirts only: The names of any 2 brands that they frequently use: Some popular brands stated by the respondents were VERO MODA, NIKE, ZARA, PUMA and TOMMY HILFIGER. Out of 60, 50% respondents preferred foreign brands.

OTHERS 3.4. With Respect to Environmental and Ethical practices used to manufacture clothes: Following six questions were asked to the respondents and their cumulative response is given below:-

they purchased were manufactured under ethical and environmentally friendly conditions. 4. Conclusion As seen from the forgoing discussion on the survey the branded clothes are preferred over non-branded clothes. The main reason for choosing branded clothes was the superior quality it offered. Quality, comfort and fitting of the branded clothes as well as consistency in design etc were the main parameters for consumers when they purchase branded clothes. Almost all the respondents said that they donated these garments away to charity once their use is over. The details of ecological impact of the manufacturing of branded garments were not known to most of the respondents and only 27% of them are aware of the harmful effects of effluents and the need for buying ecofriendly clothing. However, majority of these respondents are ready to encourage ecofriendly processing and ethical manufacturing and to boost such good practices, they are ready to buy such items at higher price too. This further confirms, the desire from within to be respectful to nature and being ethical.

Q.1 Are you aware of the term Eco-labels? A total of 52% respondents were aware of the term eco-labels. Q.2 Are you aware of the term Eco-labels in Jeans? A total of 47% respondents were aware of the term eco-labels. Q.3 Are you aware of the term Eco-labels in Tshirts? A total of 46% respondents were aware of the term eco-labels. Q.4 Are you familiar with the environmentally friendly and ethical practices used to manufacture branded clothes? Only 32% of the respondents were familiar if ethical and environmental friendly practices were used to manufacture their branded clothes and the details of these practices.

Case I Top dyed yarn fabric processingProblem faced When mercerized yarn dyed fabric was scoured or washed streaks appeared especially on areas of the fabric that was of a lighter shade, whereas in the grey form no streakiness was seen. Lot of investigations were done to understand this problem of streaky dyeing after processing. The yarn was dyed using different chemicals, fixing agents and core alkali neutralizers. After many trials it was found that the cationic fixing agent was responsible for this problem. Remedial measures It was concluded that the cationic dye fixing agent was the reason. Most cationic dye fixing agents exhaust unevenly on to dyed yarn. When the yarn dyed fabric is subjected to scouring or washing, colour from dark shades bleed into the bath and this is exhausted and fixed at the unevenly exhausted cationic dye fixed areas. The treatment with Greenclear TCSR Liq. minimizes this problem. As a preventive measure the selection of dye fixing agent becomes important. A cationic dye fixer that had a low strike rate and did not change shade on fixation was selected and this problem could be overcome. In case of many shades, an additional soaping can be done and the application of fixer could be avoided which eliminates this problem.

Mr. Edward Walter Menezes

The textile industry is comprised of a diverse, fragmented group of establishments that receive and prepare fibres, transform fibres into yarn, convert the yarn into fabric or related products, and dye and finish these materials at various stages of production. Textiles generally go through three stages that include pretreatment, dyeing, -finishing which are complex stages. In each step various parameters need to be optimized to get good subsequent treatments and ultimately quality of final textile goods. The processing parameters like temperature, pH, time, water quality, type of machine, type of fibre, type of blend are so complex that one has to have a thorough knowledge of each step with vast experience to produce a great finished fabric. Therefore, textile processing is considered to be an art rather than a science to produce and deliver on time finished fabric all the time with zero defects. Following are some of our experiences and challenges that we would like to share with you.

TEXPERIENCE Case II Uneven Dyeing in Textured Heat Setted Yarn The dyeing with Brilliant Blues is a task in order to get maximum brilliancy of shade. As in this case dyeing with Disp Blue 354, some points need to be taken care off while dyeing 1) Liquor ratio needs to be optimum (on higher side as much possible) 2) Critical Temperature Zone Concept - Dyeing program to set as per CTZ. 3) Contacts/min between fabric and liquor jet (Higher the contacts/min, better the results.)

ness of shade. Due to the dispersion stability, molecular weight and fast exhaustion at near top temperature of 1300C, use of diffusion accelerant often help to flatten the dyeing curve as the exhaustion starts early and hence dyeing slope is decreased. 2. The loading of the fabric- If you are using a Jet dyeing machine then you have to see that the loop length of the fabric is such that at least one gets 1 contact per minute ...if not 1 contact per 2 minutes. e.g.- if the fabric is 200 meters and the reel speed is 100 meters per minute, then the contact at the Jet will be 1 contact in 2 minutes. If you load the machine with double loop, the loop length will decrease to 100 meters and fabric will have 1 contact per minute. 3. pH of the bath should be strictly 4.5 minimum ...and good not use just acetic acid 4. Blue 354 has a CTZ(critical temperature zone) starting at 900C for light shades and ending at 1200C — For 0.1 % shade...for darker shades the CTZ starts at l000C and up to 1350C„, say for 1 % shade. In this zone we should have the rate of rise of temperature at 0.50C. CTZ for Blue 354 w.r.t.l % depth

Critical Temperature Zone is the temperature range in which 80% of the dyestuff gets exhausted on the polyester. In order to apply the principle of CTZ, 80% of the exhaustion of the dyestuff in the bath must be controlled in the second phase of dyeing process. The dye that gets exhausted before and after the CTZ does not contribute to unlevel dyeings. CTZ varies w.r.t depth of shade. The CTZ shifts to the left for lighter shades and to the right for darker shades. Blue 354 is one of the brightest shades in Blue that is available in disperse dyes. However, this dye is difficult to dye because of its very narrow CTZ and large molecular size ...many precautions need to be taken to get successful dyeing.

Journal of the TEXTILE Association

Steps l . The Dye dispersion is to be done very carefully. Sprinkle the dye in a container containing water at 55 -600C. Dye to water ratio should be l : 10 to 15. Dye dispersion is also of much importance while dyeing. The Dye-stuff should be dispersed by setting following conditions (Dye dispersion is important due to the nature of this dyestuff and its high molecular weight). a) Water for dilution should be of the soft quality and temperature 40-500C b) Dye should be sprinkled onto the water under slow speed stirring 30-40 rpm on hand stirring. c) The dye preparation bath should already contain 50% of the dispersing agent and 50% of the leveling agent that is necessary for dyeing operation.


The dyestuff should be added at as high temperature as possible i.e first add the chemicals, raise the temperature to 80°C and then run the colour before machine is pressurized. 6. The dyeing cycle should be as follows a. Shade is less than 0.3% 0 Add chemicals at 60 C / pH buffer - Dymax NDA Liq.- for pH 4.5 Levelling agent- Barel KB liq - 1.5 gpl Dispersing agent -Dispa HOT Liq. - 1 gpl Diffusion accelerator -Gentrate EN 200 Liq.- 1% .. / run for 5 min

The dispersion should be prepared and left standing for 10-20 min for proper dye molecule wetting. The bath should be strictly buffered to pH 4.5. The use of diffusion accelerants plays a significant role in the level304

Demineralisation- Removal of metal impurities like Ca, Mg, Fe and Cu from the Process water and fabric. Mechanism 1. Free metal and its oxide is converted into its ionic form by protonic treatment (demineralization) This ionic form is water soluble. Reaction of the oxidation of iron that may be described as follows Fe . Fe2+2cThe following redox reaction takes place 4 Fe2+ + O . 4 Fe3 + + 2 O2-

Case III Pin hole damage Pin hole damage in itself is an indication of higher degree of damage and indicates that damage has occurred on other areas of fabric, only not to that extent to form a pin hole. Pin-holes are the result of localized fiber degradation by hydrogen peroxide and is usually catalyzed by metal ions such as iron, Copper and Zinc ( Zinc comes from caustic lye from the rayon plants). There are many sources of these metal ions that should be checked. They may be present in the water supply. A common source of iron is rust from water and steam supply lines. Rust may also be present on the fabric as a result of contact between wet fabric and metal. Metal shavings from previous processing may also be a source of metals in the fabric. In addition, metal ions are inherently complexed with the fibers, and the amount will vary with source of fibers and/or growing conditions.

2. The next step is chelation. The metal ion in solution is chelated and inactivated hence does not interfere in the bleaching application 3+ Fe Sequestering agent . Metal chelate complex The iron content on textiles can be determined qualitative by spotting with Nitric acid + Pottasium thiocyanate. The presence of iron will be indicated by the appearance of a red color. The higher the intensity of the coloration more is the amount of iron present. One of our customer was facing severe problem of pin hole damage in poplin processing. Rossari offers Pin hole damage package which includes Fastrack A pdr., Kleerix PER Liq., Zystab REV Liq. and Kleenox BAS liq. to resolve the pinhole problem caused by the presence metal to achieve better fabric protection.

TEXPERIENCE a health hazard in the coning department. In the case of fabric - 100% Polyester, the Oligomer gets entrapped in the fibre structure, especially heavy gsm fabric. This leads to white stains on the fabric that are very difficult to remove. Oligomer is a smaller chain length of polyester made up of two or more molecules of basic ethylene terephthlate i.e. dimer or trimer, produced as a side reaction during the manufacture of polyester. The Oligoester because of its smaller chain length is in the form of a fine powder that is entrapped in basic polyester and migrates to the surface during high temperature polyester dyeing. Higher the depth more is the displacement of Oligomer to the fibre surface: Approximately 0.1% to 1.0% of Oligomer is produced as a side reaction in the manufacture of basic polyester.

Case IV- Coloured / dirt rings in Cheese dyeing One of our customer was facing problem of color rings in 100% white cotton yarn processing. Initially it was thought that this may be due to dirt in the machine, water hardness, processing chemicals etc. So proper machine cleaning and hardness of water was checked. But still problem persisted. Then they tried strong dispersing agent and adjusted OBA dosages in bath which reduced the problem to some extent. Then we added Instabrite paste (a great product for attracting insoluble soil and contaminants) plus Zycol TSA liq. (Special dispersant and suspending agent) in process. After addition of above chemicals they found no colour rings and 4 degree improvement in whiteness index.

Problems caused by Oligomer deposits leading to unlevel dyeings. 1. Filtration effect (Inside - out variation) due to build up of Oligomers in package. 2. Improper pump pressure due to deposits on pump. 3. Choking of spindle holes 4. Variation in rate of rise of temperature due to deposits on heating elements. 5. Duller shades 6. Dusting during coning 7. Higher energy costs.

Oligomer problem- It is a problem of process management and not like other problems where it can be prevented or completely solved. Understand that Oligomers are present from 0.1 % to 3% in the PES yarn itself and will keep coming out of the yarn or fibre during every stage of processing. It is like diabetes and has to be managed rather than look at removal. Various steps.

Oligomers are soluble at high temperature 1300C. So hot drain is a must. Oligomers are hydrolyzed by caustic and Oligo EM Liq.a special additive, hence in R/C treatment, amount of caustic has to be increased. Under alkaline conditions with increase in temp the Oligomers are hydrolyzed., so higher R/C temperature is recommended upto 80-850C. Oligomers deposit on the inside of the machine where no mechanical cleaning is possible, hence machine cleaning is the first step. Longer the dyeing cycle and darker the shade Jan - Feb 2014

TEXPERIENCE more Oligomer comes out or is displaced from the fibre, hence use shorter dyeing cycles (high rate of rise and as short as possible hold times at top temperature). 6. Higher the top temperature, more the Oligomer will tend to come out, hence do not go to temperatures of 1350C...preferably dye at l300C or even lower l250C. 7. Use dispersing agents like Gritacol OR Lliq. or Dispa HOT liq in dyeing are used at higher dosages to disperse the insoluble Oligomer. 8. Use Oligo EM Liq. in the R/C as it accelerates the hydrolysis of Oligomers and makes them soluble. 9. Use a dispersing and detergent like agent- any of our detergent like Kleenox PSF Liq. or Kleenox Knitz Liq. in the R/C and washing baths will help. A detergent during dyeing can also help to keep the Oligomers in suspension. 10. It has been found that treatment of the 100% polyester yarn with a carrier at 1100C or even 1300C as a pretreatment greatly reduces the Oligomer deposits. 11. Finally if still problem is not minimized, use finishing agents like Lubril HDR Liq. in final finish to bind the oligomer so that dusting is considerably reduced on machine.

cellulose. Biscouring treatment at raised temperature of 950C gives better results compared to caustic boil treatment. With use of Lubeshine soft Liq. in finish, we observed improvement in yarn elongation at package bottom compared to running process. Yarn hairiness observed visually is same as in the case of grey yarn. Wax ring was not observed on packages after final winding. Soiling is caused by mud and other impurities coming through water sources. We recommended to incorporate Instabrite Paste in bleach system, until clean process water was ensured. Case VII Controlled biopolishing - On of our customer complained of loss of strength after biopolishing. After investigation it was found that the fabric blend was Linen/ Cotton. Controlled Biopolishing is also one such process where selection of proper cellulase enzyme is an important step. Because some times we simply use cellulase enzymes blindly in the bio-polishing bath to get desired effect without considering type of substrate/garment present in the bath. If reactivity of your cellulase is high on a given substrate it will damage the fabric leading to strength loss. Following diagram shows rate of hydrolysis on different types of celluloses with the cellulase enzyme. It shows that rate of fibre degradation is low for lyocell fabric whereas it is very high on Linen fabric. Hence, in the above case since it was a cotton linen blend, the dosage had to be optimized for linen part of the blend and a less aggressive neutral bio-polishing agent was used.

Case VI Problems in Yarn finishing Problem of wax ring in black shade after final winding, Yarn Hairiness particularly in dark shades. Soiling on yarn packages in bleach white lots. Yarn elongation at package bottom.

Chapter 4 : Enzymes: The Vital Tools in Textile Industry Manasi Damle, Madhura Nerurkar, Ravindra Adivarekar

Journal of the TEXTILE Association

In continuation with the series of biotechnology in textiles, present article includes the application of enzymes in the textile industry. This article mainly deals with the brief introduction to enzymes, their working and the use of various enzymes in the different areas of textile processing. As mentioned in the previous articles, biotechnology refers to the use of microorganisms such as bacteria or biological substances such as enzymes, to perform industrial or manufacturing processes. Thus, the use of biological substances like enzymes in the fields of textiles very well explains the relation of biotechnology and textiles.

nature's catalysts.' Enzymes are chemically proteins in nature that consist of long chains of amino acids held together by peptide bonds. They are present in all living cells, where they perform a vital function by controlling the metabolic processes, whereby nutrients are converted into energy and new cells. The advantages of using enzymes as biocatalysts in the industrial processes include substrate specificity, mild conditions and reduced waste. The specific action of enzymes minimizes unwanted side reactions or byproducts that appear in the waste stream. The industry using enzymatic reactions can be built and operated at much lower capital and energy cost. Enzyme-based processes tend to have lower waste treatment costs. Enzymes are chemically proteins in nature. Hence, when degraded, the amino acids on which they are structured are readily absorbed back into the nature making them biodegradable (Posorske L.H., 1984).

Need for Enzymes in the Textile Industry The processing of the grey fabrics in the textile industries comprises of various vital processes like desizing, scouring, bleaching and finishing. The conventional textile wet processes involve the use of solutions of concentrated sodium hydroxide, surfactants and chelating agents at boiling temperatures (Lewin and Pearce, 1998). These chemicals, after use, are discharged into the nearby freshwater reserves as effluent. This leads to contamination of the fresh water making it unfit for human consumption. Moreover, these chemicals damage the outer mucus layer that coats the fishes protecting them from parasitic bacteria, fungi and protozoa. According to Lenntech, consumption of such contaminated fresh water disrupts the digestive and endocrine system of humans. In addition, these processes requires a high energy input, generate a large amount of biochemical and chemical oxygen demand. On the fabric level, oxidative damage may also take place resulting in reduced tensile strength of the fabric. To prevent any damage to the ecosystem, it is important to minimize the use of traditional chemicals in the various stages of textile processing. Thus, inclusion of enzymes in the textile wet processes is the need of the hour.

Fruit, cereals, milk, fats, meat, cotton, leather and wood are some typical substrates for enzymatic conversion in industry. Both the usable products and the waste of most enzymatic reactions are non-toxic and readily broken down. Finally, industrial enzymes can be produced in an ecologically sound way where the waste sludge is recycled as fertiliser. Microbial enzymes are often more useful than the plant and animal derived enzymes because of the great variety of catalytic activities available, fast life cycle, comparatively high yields, easy handling and transport, production using controlled fermentation techniques, minimum space required for storage of microbes, regular supply due to absence of seasonal variations and rapid growth of microorganisms on inexpensive media. Microbial enzymes are also more stable than their corresponding plant and animal enzymes and their production is more convenient and safer (Wiseman A., 1995). Mechanism of Enzyme Action The basic mechanism by which enzymes catalyze chemical reactions start on, is by the binding of the substrate (or substrates) to the active site on the enzyme. The active site

TEXNOTE is the specific region of the enzyme which joins to the substrate. Enzymes are large protein molecules, the molecular weights of which range from several thousand to several million. The substrates on which enzymes act usually have molecular weights of several hundred. Due to the difference in size between the two, only a fraction of the enzyme is in contact with the substrate; the region of contact is called the active site. Usually, each subunit of an enzyme has one active site capable of binding substrate. The binding of the substrate to the enzyme bring about changes in the distribution of electrons in the chemical bonds of the substrate and ultimately accelerates the reactions that lead to the formation of products. The products are released from the enzyme surface to regenerate the enzyme for another reaction cycle.

form catalytic reaction effectively. Enzyme (E) wraps around substrate (S) to distort it and forms an enzyme-substrate complex (ES) .fast reaction to produce product (P) E + S . ES . P + E Enzyme is not used up in the reaction (unlike substrates)

Solubility : Enzymes as proteins are soluble in water or dilute salt solution.

Molecular Weight : Enzymes have a very high molecular weight varying from 10000 to several thousands.

Enzymes are charged molecules : Due to presence of amino acids, each enzyme has a charge. The charge depends on the pH of the solution. At a very low pH the amino acids are fully protonated and there is a positive charge on the proteins, as the pH is increased, the protein loses the proton to neutrilize the OH group and becomes a zwitter ion. As more alkali is added, the NH3 group gives its H+ and protein becomes positively charged.

The active site has a unique geometric shape that is complementary to the geometric shape of a substrate molecule, similar to the fit of puzzle pieces. This means that enzymes specifically react with only one or a very few similar compounds.

Enzymes have Buffering capacity : Enzymes are amphoteric molecules i.e. they behave as both acids and bases due to the presence of both carboxyl groups and amino groups.

Lock and Key Theory The specific action of an enzyme with a single substrate can be explained using a Lock and Key analogy first postulated in 1894 by Emil Fischer. In this analogy, the lock is the enzyme and the key is the substrate. Only the correctly sized key (substrate) fits into the key hole (active site) of the lock (enzyme).

Each enzyme has a specific isoelectric pH [PI] : It is the pH where the net charge on the protein is equal to zero so they do not move in an electric field. Above PI, negatively charged enzyme can move in an electric field. Below PI, enzyme is positively charged and can move under a electric field.

Co-factors and co-enzymes : A cofactor is a non-protein chemical compound that is bound to the enzyme and is required for the enzyme's activity. Egs: Mg2+, Mn2+, Zn2+. Coenzymes are organic molecules that are required by certain enzymes to carry out catalysis. Eg: NAD, FAD, TPP.

Apoenzyme and Holoenzyme : An inactive enzyme, without the cofactor is called an apoenzyme while the complete enzyme with cofactor is the holoenzyme.

Enzyme activity : It is defined as the amount of enzyme that will convert a certain amount of Substrate to Product in a specified period of time under conditions of constant temperature and pH. The international Enzyme Commission (IEC) has adapted a standard unit of enzyme activity called The International Unit (IU). It is defined as the amount of enzyme that can convert one ?mole of substrate into product per minute at 25°C.(1 .mmole = 1 x 10-6moles). Katal: It is defined as the number of moles of substrate transformed into product

The forces that attract the substrate to the surface of an enzyme may be of a physical or a chemical nature. Electrostatic bonds may occur between oppositely charged groups. Such electrostatic bonds can occur with groups that are completely positively or negatively charged (i.e., ionic groups) or with groups that are partially charged (i.e., dipoles). The attractive forces between substrate and enzyme may also involve so-called hydrophobic bonds, in which the oily, or hydrocarbons of the enzyme and the substrate are forced together in the same way as oil droplets tend to coalesce in water.

Smaller keys, larger keys, or incorrectly positioned teeth on keys (incorrectly shaped or sized substrate molecules) do not fit into the lock (enzyme). Induced fit theory The favored model for the enzyme-substrate interaction is the induced fit model. This model proposes that the initial interaction between enzyme and substrate is relatively weak, but these weak interactions rapidly induce conformational changes in the enzyme that strengthen binding. The induced fit theory was proposed by Daniel Koshland in 1958. The theory can be summarized as follows: ◆ ◆

Enzyme's shape changes when substrate binds to active site. Amino acids are moulded into a precise form to per-

Enzyme turnover Number : It is redefined as the number of moles of substrate transformed per minute per mole of enzyme (Units per mmole of active site or catalytic center under optimum conditions.

Enzymes are target specific : Enzymes are very specific in their action as compared to inorganic catalysts such as acids, bases, metals and metal oxides. Enzyme can break down particular compounds. In some cases, their action is limited to specific bonds in the compounds with which, they react.

Application of enzymes in Textiles A range of enzymes like amylases, cellulases, catalase, pectinase and protease for various textile wet-processing applications like desizing, bio-polishing, denim finishing, bleach clean-up, bio-scouring and de-wooling are being used.

Enzymes Amylase

Name of the Process in which enzyme is used Desizing


1] Biopolishing

Role of Enzyme Starch has for a long time been used as a protective glue of fibres in weaving of fabrics. This is called sizing. Enzymes are used to remove the starch in a process called desizing. Amylases are used in this process since they do not harm the textile fibres. Appearance and feel of cotton and other natural fibres based on cellulose can be improved by an enzymatic treatment known as BioPolishing. This treat ment gives the fabric a smoother and glossier appe arance. The treatment is used to remove 'fuzz' - the tiny strands of fibre that protrude from the surface of yarn. A ball of fuzz is called a 'pill' in the textile trade. After BioPolishing, the fuzz and pilling are reduced. The other benefits of removing fuzz are a softer and smoother handle, and superior colour brightness. Enzymes have replaced the use of volcanic lava stones in the preparation of Denim (special soft cotton based fibre where the dye has been partially faded away) from an indigo-dyed cotton fibre to achieve a high degree of dye fading. The stones caused consider able damage to fibres and machines. The same effect can be obtained with cellulase enzymes. Natural fabrics such as cotton are normally bleached with hydrogen peroxide before dyeing. Bleaches are highly reactive chemicals and any peroxide left on the fabric can interfere with the dyeing process. A thorough 'Bleach

Cleanup' is necessary. The traditional method is to neutralize the bleach with a reducing agent, but the dose has to be controlled precisely. Enzymes present a more convenient alternative because they are easier and quicker to use. A small dose of catalase is capable of breaking down hydrogen peroxide into water and oxygen. Compared with the traditional clean-up methods, the enzymatic process results in cleaner waste water or reduced water consumption. Catalase for bleach clean-up i.e.removal of residual hydrogen peroxide (as peroxide killers) after the bleaching of cotton Removal of pectic substances from cotton fibres. Bast fibres are soft fibres formed in the groups outside the xylem, phloem or pericycle eg. Ramie and sun hemp. The fibre contains gum which must be removed before its use in textile making. The chemical degumming method is polluting, non-toxic and non-biodegradable. Hence, pectinases are used in the removal of this gum. Pectinases have been used in the retting of flax to separate the fibres and eliminate pectins.

3] Retting of Plant fibres 1] Wool Processing

The use of protease enzymes for a range of wool finishing treatments aims at increased comfort (reduced prickle, greater softness) as well as improved surface appearance and pilling performance. Proteases help in the complete and uniform sericin removal, retention of tensile properties, and improvement of surface smoothness, handle, and lustre of silk.

In this chapter we have focused upon enzyme mechanism and their role in textile industry. Enzymes are used in textile wet processing and enzymes like cellulase are used for finishing purpose of textile. One of the important finishes on textile that is being looked upon in almost every area of textile manufacture is antimicrobial finishes. In the upcoming chapter, different antimicrobial agents, their mode of action and testing methods to study antimicrobial efficiency of fabric will be stressed upon.

A maiden venture of Textile Excellence, the country's leading textile publication, ITMACH 2014, from January 22-24, was also the first textile machinery event of its kind, organized in the country's largest powerloom weaving cluster. ITMACH 2014, Bhiwandi, was the first in the series of localized textile engineering exhibitions that the organizers - Textile Excellence - have planned.

The guests of honor, in their address, hailed the efforts of Textile Excellence for organizing the show in Bhiwandi cluster. According to Rasheed Tahir Momin, "Weavers in this cluster today realize that they need to upgrade and move up the value chain to survive in a competitive market. Technology upgradation for this is very important. Bringing in the right machines to this market, through a show like ITMACH, is very helpful for this cluster. I am sure the show will be very successful." Rupesh Mhatre, in his address, said, "Powerlooms are the mainstay of the economy of Bhiwandi. Millions of families are dependent on this industry. With changing times, weavers here are realizing the importance of improving their production and productivity. ITMACH will help them to understand the kind of machines and technologies they can invest in."

and move ahead." Around 100 machinery suppliers - Indian and international participated in ITMACH 2014. Around 4,000 business visitors came to the show on the first day.

Companies showcasing Indian made and Chinese machines, in particular, have booked many orders at the show. According to Hemant Shah, Director, Manisha Overseas, they showcased Waterjet looms and other very unique technologies for the Bhiwandi and the decentralized powerloom sector. He said that the response was overwhelming. Bhiwandi weavers need to be made aware of the various technologies in the market, and this show has fulfilled this objective.

Out of 23 lakh registered powerlooms in the country, only 1.05 lakh looms are shuttleless loom. Offtake of powerloom sector under TUFS has been negligible. This highlights the immense investment potential in machinery in Bhiwandi and other powerloom clusters. The government, through its comprehensive cluster development scheme, is encouraging investment in TUFS compatible machinery, as a minimum benchmark.

Hasmukh Textile Works is another company that offers rapier machines and other weaving and processing machines, imported from China. "There is a great deal of interest in these machines from the decentralized sector. The machines are cost-effective, have good performance, and are well suited to the needs of the powerloom sector. This sector still hesitates to invest in high end technology. The medium range Chinese machines are much in demand here. It will take some more years for this industry to upgrade to higher technology levels."

Flow of visitors was continued on 2nd Day and recorded over 6000 visitor registrations. Exhibitors evidenced satisfaction with the response at the show. While visitors from Bhiwandi were there, business delegates also came in from Ichalkaranji, Malegaon, Solapur, Ujjain, Ludhiana, Panipat, and also from southern India.

The exhibition showcased technologies and machines related to weaving and weaving preparatory, spinning, processing and finishing, printing, and other related segments. ITMACH 2014 offered a one-of-a-kind opportunity to business visitors from Bhiwandi and other textile clusters across the country, to see the latest and most appropriate technologies spanning the textile value chain.

Exhibitors received serious enquiries during the show. Many business deals have been finalized. There was a lot of interest in weaving and allied technologies, especially of Indian origin. Weavers are finding these machines to be a good fit for their up-gradation needs towards shuttleless looms, in terms of productivity, price, service etc. International exhibitors too received good response.

With encouraging response from exhibitors and visitors, the organizers have announced ITMACH 2015. Most of the first-time exhibitors have confirmed participation in ITMACH 2015. "The local industry and exhibitors have evinced keen interest in such sustained efforts. The industry in Bhiwandi has given us wholehearted support in this venture. We will therefore strive to make this a regular event, with the objective of helping the industry's up-gradation process," said the organizers.

On the last day of ITMACH 2014 there was a huge crowd descending on the exhibition grounds, as there was there a weekly holiday in Bhiwandi.

R 35 guarantees excellent piecing for high acceptance in downstream processing In today's yarn markets, an inadequate piecing quality alone can cause an otherwise high-quality yarn not being accepted in downstream processing. For the new Rieter R 35 semi-automated rotor spinning machine the renowned AMIspin piecing process has been optimized and is more operator-independent.

individual feed drive for the sliver, applying piecing technology known from other Rieter rotor spinning machines. After preparing the yarn end and cleaning the rotor, the piecing process is launched automatically as soon as the box is closed. As a result the quality, speed and success rate of AMIspin piecings have been improved. Optimized yarn entry for fast and easy piecing With the R 35 the insertion of the prepared yarn end into the exit tube has been simplified, because the yarn entry is now from the front (Fig.1). This accelerates the piecing operation and allows reduction of the operator time. It guarantees excellent piecing quality with high value for the yarn users. For the spinner it helps to maintain higher machine efficiency even with a high ends down rate and fewer operators. Individual sliver feeding drive for better piecing quality Immediately after each yarn break, the single feed drive pulls back the sliver into a protected position, thus ensuring that the piecing always is formed from undamaged fibers. During piecing the individual drive allows more exact sliver feeding to further optimize the appearance and strength of the piecing.

Sales totaled 1 035.3 million CHF, equivalent to an increase of 17%. Rieter had a backlog of orders in hand of some 765 million CHF at the end of 2013. This will ensure a high capacity utilization until well into 2014. Rieter will publish its full annual financial statements and annual report for 2013 on March 18, 2014. CHF million

Orders received In the year under review, new orders received by Rieter increased by 50% to 1 259.4 million CHF. After developing especially vigorously in the first half of 2013, order intake slowed slightly in the second six months, but still remained above the long-term average. This trend was especially true in Turkey, where demand had been particularly strong with the support of government development schemes. Rieter booked substantial new orders in China, especially in the first six months, due to the further expansion of its local presence. However, investments by Chinese spinning mills waned toward year-end due to large raw material inventories and growing difficulties with financing investment projects. Healthy demand for Rieter products nevertheless continued throughout the year in a number of Asian countries, such as Pakistan, Uzbekistan, South Korea, Bangladesh, Indonesia and Vietnam. Spinning mills in the US are renewing capacity as the industry benefits from a competitive cost structure. Business here developed briskly in the second half in particular, and Rieter secured substantial orders for rotor spinning machines. Orders received in India rose in the second half, albeit still at a modest level. Rieter posted an increase in order intake at both Business Groups, with the striking momentum in the first six months being attributable especially to orders for complete installations from Spun Yarn Systems. Compared to 2012, Spun Yarn Systems (the machinery business) posted a 56% increase in new orders to 1 084.3 million CHF. At Premium Textile Components (the components business) order intake increased by 21% in 2013 to 175.1 million CHF.

After a subdued start to the year, the market for shortstaple fiber machinery and components gained momentum in the course of 2013. Spinning mills' margins continued to develop favorably, and this stimulated customers' willingness to invest. This positive trend was broad-based in regional terms and apparent in a large number of national markets. Following a strong initial six months, demand stabilized in the second half of the year, but remained at a pleasingly high level. The positive trend in order intake and sales in 2013 underlines that Rieter is on the right track with the innovation and expansion strategy it has been implementing since 2012. Demand for the company's offering, expanded by major product launches, has been very good in both our traditional and new markets. Rieter has further developed its already strong market position with the implementation of the large-scale investment program in 2012/2013 aimed at further growth and focusing on expansion in Asia, innovation and proJan - Feb 2014

cess improvements. With its product range centering on specific markets and its new plants the company is ideally positioned with a worldwide operating network. Spinning mills in all major markets are increasingly placing their confidence in machinery and components which enable a high degree of automation to be achieved in conjunction with higher productivity and yarn quality with lower energy consumption. As the sole global supplier of integrated systems for all four spinning processes, Rieter can optimize the entire spinning operation in line with customers' specific needs. This is a crucial and lasting competitive advantage.

NEWS Sales The sales trend at Rieter in 2013 was also very good. The figure of 1 035.3 million CHF was 17% higher than a year earlier. All regions recorded increases, with only Europe posting slightly lower sales. Expanded and modernized manufacturing capacity enabled Rieter to process orders promptly and post a 17% increase in sales in the second half of the year compared with the first six months.

Textile & Garment import and export in China 2013 In 2013, China's textile and apparel export faced the negative situations from 2012: rise of labor costs, the great gap of cotton price in domestic and international markets, soaring exchange rate of RMB and transfer of orders, etc. However, there are opportunities amidst these difficulties: gradual economic recovery of major economies, slight rebound of international demands and the domestic policies and measures stabilizing the growth of foreign trade that have shown effect. Thanks to the transformation and upgrade of export-oriented enterprises, China's textile and apparel export in 2013 stood the pressure and gradually maintained rapid growth. By November, the export value totaled $258.07 billion, up 11.8 percent, and the import value reached $24.7 billion, up 10.8 percent.

A. Import and Export 1. Starting the second quarter, the import and export have been growing stably and rapidly. The whole year's growth will outnumber our expectation. 2.

In general trade, both the import and the export grew and the export trade modes and structures were further optimized.


Enterprises of all types maintained growth in import and export, with private enterprises taking the lead.


Exports to major markets varied and China's shares in Europe, the United States and Japan went down.

Japan was the only traditional market where China's textile and apparel export reduced.

China's export to ASEAN grew rapidly and apparel has become the major product pushing the growth.

Jan - Feb 2014


The growth in emerging markets continued and China's share in non-traditional markets went up.

The share of China's products in Europe, the United States and Japan reduced.


Export of commodities of various categories went up with apparel export growing in quantity and price.


Most provinces and municipalities in China maintained growth with different characters in the east China and central-west China.


Cotton import plummeted greatly compared with the previous year and the gap in cotton price in domestic and international markets maintained large.


Future planning for the development of Industry


China's position in the global textile and apparel trade.


Measures taken by the Chinese enterprises.

Attaching greater importance to the domestic market.

High-grade enterprises paying more attention to brand construction and development.

Reaching consensus in strengthening research, development and design to produce high valueadded products.

Some enterprise tried e-commerce in cross-border business and have maintained certain markets with small amount of high-quality but inexpensive products.

Owing to the high cotton price and labor costs, as well as free trade agreements, some enterprises established factories overseas. It's not bad to transfer some low-end orders to overseas markets.


Owing to the rebound in European and American markets, the fire disaster in Bangladesh, unstable situation in Cambodia and the problems in labor productivity, some orders came back to the Chinese market.

Market expansion of the shirt segment

At the Parisian trade fairs this season, TENCEL® shirts in a blend with cotton have priority. The cotton blend concept "Natural Connection" which was launched in September 2013 will be continued in 2014. A shirt with an added value

As an article of clothing, the shirt is traditionally made of natural materials since it is worn directly next to the skin. Cotton is particularly popular with consumers as a material for shirts. Adding TENCEL® to traditional shirt fabrics produces a host of advantages. The moisture management and skin sensory characteristics are improved due to the good skin sensory properties of TENCEL®. Cotton and TENCEL® are ideal partners in the shirt sector. They go together perfectly and enhance each other with their properties. Both fibers are from Nature and reveal similar benefits such as good breathing properties. "Even a small blending ratio with TENCEL® gives shirts of cotton a new definition. As a result of this admixture, the hand, moisture management and gloss can be influenced in a positive manner," Andreas Gürtler, head of the Performance Apparel Segment at Lenzing explains. Thus the innovative potential of cotton-TENCEL® fabrics is great. Depending on the blending ratio, the look and properties can be changed to suit your needs. Even easycare properties can be improved.

"In-house estimates tell us that 16,000 tons of cotton are used in woven shirts and blouses. The shirt segment is seen as a growth segment for TENCEL® for this very reason since even a small percent of TENCEL® can have a positive influence on processing and mean greater comfort for the end consumer," Andreas Gürtler says. "Particularly fabrics of longstaple cotton and TENCEL® are unbeatable in terms of the quality and look. Already 60% of the TENCEL® fabrics certified according to Lenzing's quality criteria are used for shirts and blouses. Of this one third is blended with cotton. The goal is to further increase the share with cotton blends in the seasons to come," Gürtler continues. To promote fabrics with cotton and TENCEL® more effectively, the Lenzing certification system will be further extended.

BCF plant business still on the road to success At this year's Domotex Asia from 25 - 27 March, Oerlikon Neumag and Oerlikon Barmag presented their solutions for an efficient carpet production. In Hall W3, booth F23, the focus of the information will be on the 3-end BCF plant S+ from Oerlikon Neumag, as well as on the new tape yarn solution for carpet backings, EvoTape with WinTape, from Oerlikon Barmag.

Domotex Hanover was a great success Oerlikon Neumag was very satisfied during the four lively fair days in Hanover mid January. After two very successful years in the BCF business, the market leader furthermore records very good transac-tions. Three contracts were successfully concluded during the Domotex. The BCF plants S+ und Sytec One are in high demand. Whereas the S+ convinces for commercial applications, the Sytec One is especially suitable for demanding production processes. "With the S+ and Sytec One, we have an excellent position on the BCF market. We can practically cover all cus-tomer requests with these two plants", summarized Martin Rademacher, Sales Director BCF.

The Asian market is still regarded as a small market with development potential due to its classical consumer behavior on the carpet sector, especially for export. The market is very much focused on the production of contractual goods. There seems to be a change coming. "Our customers are always looking for innovations and new products", explains Alfred Czaplinski, Sales Manager BCF. "Due to the high flexibility of our S+, we can practically cover every application".

About Oerlikon Manmade Fibers With its Oerlikon Barmag and Oerlikon Neumag brands, Oerlikon Manmade Fibers is the world market leader for manmade fiber filament spinning systems, texturing machines, BCF systems, staple fiber systems and artificial turf systems and - as a service provider - offers engineering solutions for the entire textile value added chain. As a future oriented company, the research and development at this division of the Oerlikon Group is driven by energy-efficiency and sustainable technologies. With the expansion of the product range to include poly-condensation systems and their key components, the company now caters to the entire process from the monomer all the way through to the textured yarn. The primary Oerlikon Barmag markets are in Asia, and - for Oerlikon Neumag - in the USA, Turkey and China. Correspondingly, Oerlikon Barmag and Oerlikon Neumag - with just under 2,500 employees has a worldwide presence in 120 countries as part of the Oerlikon Manmade Fibers net-work of production, sales and distribution and service organizations. At the R&D centers in Rem-scheid, Neum端nster and Chemnitz, highly-qualified engineers and technicians develop innovative and technologically-leading products for tomorrow's world.

Oerlikon Neumag focusses on the S+ The 3-end S+ not only convinces due to the efficiency of 99% and therefore raw material cost savings. It also covers a wide spectrum of producible total titers of 600 - 4000 dtex. Furthermore, all polymers from polyester, via polypropylene up to polyamide 6, can be processed on the multipolymer plants without conversions.

Journal of the TEXTILE Association

Since its introduction to the market in 2011, the S+ is the most-sold BCF plant and produces economi-cal, high-quality BCF yarns worldwide. Efficient combination of Oerlikon Barmag: EvoTape and WinTape Focussing on the new developments for tape yarn production for carpet backing, introduced at last year's Plastics Trade Fair, we have a significant increase in profitability: Oerlikon Barmag has achieved a quantum leap with up to 50% more output in comparison with usual market standard plants.

While highlighting the problem of shortage of labour and shortage of skills required to run today's high tech machines faced by the manmade fibre industry, Mr. Thanawla called upon Gujarat government for a clarification on eligibility of machines. He informed that the Government of Gujarat was providing interest subsidy of 5% to the weaving preparatory machines in an attempt to ensure that the high speed automatic loom are operating at its peak efficiency. This was only possible with perfect preparation.

Oerlikon Manmade Fibers arranged their annual technical Seminar cum Customer Meet on 20th February 2014 at Treat Resort in Silvassa. During the seminar various eminent speakers from Oerlikon Barmag & Oerlikon Neumag, Germany presented the latest developments in the field of POY, FDY, Staple Fiber & CP. Addressing the Oerlikon Manmade Fibers Customer Meet, Mr. Khursded Thanawala, Managing Director, Oerlikon Textile India Private Ltd. pointed out that over the years, great technological innovation and progress has been made in the manmade fibre industry, making this fibre user friendly, easy to produce and having a wide variety of application in clothing and industrial applications. He said that there is a great potential for the growth of the manmade fibre industry (MMF) in India, given the right policies and the right encouragement.

Mr. Thanawala pointed out and requested the Gujarat Government to clarify to the manmade fibre industry that the texturizing machine was classified under the machines for weaving preparatory and would be eligible for the same 5% interest.

Further, Mr. Thanawala emphasized that "we in the MMF industry to some extend feel like 'orphans'. The MMF industry is part of textile value chain. But when we go to Textile Ministry in New Delhi, the authorities say that we do not belong to textiles but to petrochemical industry. And when we go to Petrochemical Ministry, they are interested only in refineries and petroleum products and not concerned in manufacture of POY, FDY and other polyester products".

Dr. Chandan Chatterjee addressing the audience

Mr. Thanawala informed that 55% of India's polyester industry was located in the Union Territory of Silvassa and 43% in the State of Gujarat. The industry has flocked to the Union Territory of Silvassa due to cheap availability of power and other facilities and benefits. It is now well known that there is not much more physical room for expansion of this industry in the Union Territory of Silvassa, so entrepreneurs are now, beginning to look at alternate sites. Given the necessary inducements, almost all of them would be more than happy to expand in the State of Gujarat, Oerlikon Chief pointed out and called upon the Gujarat Government to look at this aspect and encourage the growth of the manmade fibre industry by the Jan - Feb 2014
