Industrial Attachment Intramex Group Introduction Textile and garments sector is the biggest and fastest growing sector in Bangladesh. It is also the highest foreign currency earning sector in Bangladesh. Among this sector, Knit garment is growing very rapidly due to smaller investment requirement, greater backward linkage facility & higher profit than woven garments. That’s why export knit garments is increasing steadily for last few years and up to now. Industrial training is very much important for textile education. I have gathered a lot of information’s from this Industrial training which will help me to lead my future life and as well as the greater development in textile fields. Textile education can’t be completed without industrial training. Because this industrial training minimizes the gap between theoretical and practical knowledge and make us accustomed to industrial environment. I got an opportunity to complete two-months long industrial training at INTRAMEX GROUP, which is a 100% export-oriented composite Knit Dyeing Industry. It has well planned & equipped fabric dyeing-finishing and garments units in addition to facilitate knitting and knitwear manufacturing.

Interlock Type of Collar: Tipping Solid collar Raising collar Folding collar Cuff Emboss Faults, Causes & their Remedies in Knitting: Hole Mark: Causes: Holes are the results of yarn breakage or yarn cracks. During loop formation the yarn breaks in the rejoin of the needle hook. If the yarn count is not correct on regarding structure, gauge, course and density. Badly knot or splicing. Yarn feeder badly set. Remedies: Yarn strength must be sufficient to withstand the stretch as well as uniform. Use proper count of yarn. Correctly set of yarn feeder. Knot should be given properly. Needle Mark: Causes: When a needle breaks down then needle mark comes along the fabrics. If a needle or needle hook is slightly bends then needle mark comes on the fabrics. Remedies: Needle should be straight as well as from broken latch. Sinker Mark: Causes: When sinker corrodes due to abrasion then some times cannot hold a new loop as a result sinker mark comes. If sinker head bend then sinker mark comes. Remedies: Sinker should be changed Star : Causes: Yarn tension variation during production. Buckling of the needle latch. Low G.S.M fabric production. Remedies: Maintain same Yarn tension during production. Use good conditioned needles. Drop Stitches: Causes: Defective needle. If yarn is not properly fed during loop formation i.e. not properly laid on to the needle hook.


Take-down mechanism too loose. Insufficient yarn tension. Badly set yarn feeder. Remedies: Needle should be straight & well. Proper feeding of yarn during loop formation. Correct take up of the fabric & correct fabric tension. Yarn tension should be properly. Oil stain: Causes: When oil lick through the needle trick then it pass on the fabrics and make a line. Remedies: Ensure that oil does not pass on the fabrics. Well maintenance as well as proper oiling. 07. Rust stain: Causes: If any rust on the machine parts. Remedies: If any rust on the machine parts then clean it. Proper maintenance as well as proper oiling. Pin hole : Causes: Due to break down or bend of the latch, pin hole may come in the fabric. Remedies: Change the needle Grease stain: Causes: Improper greasing Excess greasing Remedies: Proper greasing as well as proper maintenance. 10. Fly dust: Causes: In knitting section too much lint is flying to and fro that are created from yarn due to low twist as well as yarn friction. This lint may adhere or attaches to the fabric surface tightly during knit fabric production. Remedies: Blowing air for cleaning and different parts after a certain period of time. By cleaning the floor continuously. By using ducting system for cleaning too much lint in the floor. Over all ensure that lint does not attach to the fabric. 11. Yarn contamination: Causes: If yarn contains foreign fiber then it remains in the fabric even after finishing, If lot, count mixing occurs. Remedies: By avoiding lot, count mixing. Fault less spinning. 12. Yarn Faults:

On-Line

Off-Line

Online Quality control: There are two types of online quality control. These are as follows: Raw material control: Raw material control means control the quality of raw materials (e.g.- Quality of Grey fabric, Dyes, Chemicals and Auxiliary) Process control: Process control means the selection of right process and controlling of some parameters. Such as PH, Water hardness, water volume, Temperature, Reel Speed, Pump pressure, etc. Online Tests: Dyed fabric. Shade check. Wash fastness. Water fastness. Crocking fastness. Laboratory: Laboratory is the heart of dyeing Industry. An efficient laboratory can increase the efficiency of dyeing. So, laboratory in-charge is sometimes called pilot. Before bulk production a sample is sent to buyer for approval. Laboratory supplies the recipe to the floor. Purpose of Laboratory: Get color approval from buyer.


Recipe supply to the floor. Shade correction. Minimize the deviation between bulk and laboratory. Laboratory line: Standard sample: At first recipe % of standard sample is measured by CCM (computer color matching) system. Laboratory Trial: Then by taking those recipe laboratory officers produce laboratory trial and match with standard according to buyer requirement. Approved Sample: Then sample swatch, which is matched with the standard, is send to buyer for approval. Off-Line Tests: Off-Line tests for finished fabrics are divided into two groups. These are as follows: Physical tests Chemical tests Physical Tests: GSM of Fabric. Abrasion resistance / Pilling. Dimensional stability test. Spirality test. Color fastness to rubbing test (Dry / wet). Bursting strength test (For Knitted fabric). Tensile Strength test (For Woven fabric). Chemical Tests: Color Fastness to washing. Color Fastness to light. Color Fastness to heat. Color Fastness to actual laundering Color Fastness to Chlorinated water. Color Fastness to water spotting. Color Fastness to perspiration. Color Fastness to Seawater. Flammability test. Fibre analysis. PH test. Spray test (water repellency). Phenolic yellowing. Quality standard: Here in the factory they are following ISO standards for their testing purpose. But testing standard depends on buyer requirements. SOME TEST PROCEDURE Color fastness to rubbing (wet & dry): Procedure:


At first take a sample of size (14 × 5) cm at Wales & Course wise. Put the crocking cloth on to the finger & stag by finger clip & run 10 times in 10 seconds manually & assess the crocking cloth with gray scale. Place the crocking cloth on the water, it will sucked some water and then squeeze the crocking cloth. Then place the wet rubbing cloth on to the finger and stag with finger clip and run 10 times in 10 seconds manually. Then assess the crocking cloth by gray scale for wet rubbing. Wet and dry rubbing are checked according to buyer’s requirement. Color fastness to washing. (ISO/05-CO6): Procedure: Size of specimen: Cut sample & multifibre at (10 × 2) cm then stitch. Detergent: 4g/l ECE detergent (WOB) + 1g/l sodium per borate put in distilled water & cooled at 20°C & measured PH (where necessary). Run the program in the following way: Test no.

Dry at 60°C by hanging or by flat iron pressing but temperature should not less more than 150°C. Pilling test: Procedure: Cut the fabric 12.5 x 12.5cm & balance mark should be 10cm by using template. Then sewn the fabric so that it can be firmly fit in the tube a moulded polyurethane tube. Then four tubes are placed in a box & start 60±2 rev/min for 5 hrs or according to buyer requirement. Here mainly used 3hrs (1100 cycle). Then assess the pilling by putting tested specimen on the viewing cabinet & compare with standard photographs. Shrinkage & Spirality test: Buyer’s requirements: Template size: 50cm & 35cm, 25.5cm &18cm (use after quick wash). Shrinkage: length wise--- 5% Width wise----5% Spirality:

Left -------- 5% Right -------- 5%

Procedure: At first take two ply of fabric & put the template (50cm) on to the fabric. The template has 8 holes. Both length & width wise the template holes can measure 35cm at 3 places. Then we mark the 8 holes by permanent marker & also at the edges of the template. Then sewn the fabric & it is given to the washing m/c for run at 60°C for 60minutes with water. After that dry the sample & then measure the fabric Spin speed --- 500rpm Drum speed--500rpm Calculation


Shrinkage Test: Lengthwise: After wash – Before wash = ----------------------------------×100 Before wash Width wise: After wash – Before wash = ----------------------------------×100 Before wash Spirality test: Left side + Right side 2 Length(wid th for H & M) × 100 % =

Color fastness to water (ISO 105 EO1& EO2): Sample size: Cut the specimen & multi-fiber at 10×2cm & sewn together. Solution: Wet in distilled water at room temperature & it will suck water. Place it in acrylic resin plates & put the weight on to the plates. Keep it in oven & keep the temperature at 37± 2°C for 4hrs. Open the specimen & dry it in the air hot exceeding 60°C. Assess the staining & shade change with gray scale. Color fastness to perspiration Alkaline & Acid solution (Method: ISO 105 E04): 1) Procedure: Cut the specimen & multifibre at 10×2cm & sewn together. 2) Prepare solution: Alkaline Solution: 0.5g/l of 1-histadine mono hydrochloride monohydrate 5g/l of sodium chloride This solution is brought to pH -8 with 0.1 mole/l caustic solution. Acid solution: 0.5 g/l of 1-histadine monohydrochloride monohydrate 5g/l of sodium chloride. 2.2 g/l of sodium dihydrogen orthophosphate dehydrate. This solution is brought to pH-5.5 with 0.1 mole/l caustic solution. 3) M: L = 1: 50 4) Wet the specimen in flat dish containing acid & alkaline solution & keep for 30min. Then take the specimen & squeeze the excess solution by two glass rods. 5) Put the specimen in to the acrylic resin plates & put wt. on the plates. 6) Keep it in the woven at 37°C ± 2°C for 4hrs. 7) Open the specimen 6 multi fibre & dry separately in the air temperature not exceeding 60°C. 8) Access the staining & shade change with grey scale. 6.17 PH Test:


Procedure: Take 2gm sample fabrics and cut into small pieces. Then put it conical flax with 100cc water (M: L -1:50). Then shake it 15 min, then place it in a shaker m/c for 1 hour. Then check PH by PH meter. GSM TEST: Procedure: GSM is the most important factor. There is a GSM cutter. The sample cut by the GSM cutter is weighted in the electronic balance. The reading (in gm) from the balance is multiplied by 100 to get the value of GSM. RESPOSIBILITY OF OFF-LINE quality control: To check the following things: Inspection of fabric in the inspection M/C under 4-point system. Yarn count and lot no. Buyer. Design. Stitch length of grey fabric. Shade of grey fabric within one order. RESPOSIBILITY OF ON LINE quality control: To check the following things: M/C Dia/Gauge Buyer Design Grey fabric GSN & Stitch Length Yarn count & Lot no Yarn whether approved or not by Q.C.

Technology of dyeing machine: INTRAMEX dyeing unit used special types of dyeing machine. In these machine, the Jet and Winch technology is combined i.e. during dyeing, dye liquor circulate through the machine like jet dyeing machine also the fabric is circulated through the winch as like winch dyeing machine. This combination is made for better dyeing of the fabric. Main parts of dyeing machine: The main parts of the dyeing machine areMain tank Reserve tank/PT tank Additional/Mixing tank Main pump Heat exchanger Filter The description of the main parts of the machine is as follows – Main tank: Main tank is the largest part of the dyeing machine. This is the main dye bath which contains the dye liquor & the fabric. The size of the tank depends on the capacity of the machine. Liquor & fabric circulates in the main tank during dyeing process. There may have different number of nozzle connected to main tank according to the machine capacity. Each nozzle may handle 300-900m of fabric.

Main tank Reserve/ PTtank: This tank is mainly used for storage of hot water that will be used for the dyeing of fabric. The temperature of water in the P.T. tank is maximum 800C. By using this hot water in the machine during dyeing there is a reduction of time for heating the water in the main tank which results in the reduction of total dyeing time.

Main pump: This is one of the essential parts of the dyeing machine. This is used for displacing of dye bath liquor causing a flow from main tank to heat exchanger through filter. That means the pump ensures the liquor circulation throughout the dyeing process. Heat exchanger: During the different stage of dyeing (also pre-treatment, after-treatment), there is a need of increasing or decreasing the temperature of dye liquor gradually. We cannot use liquor of required final temperature directly because there may be possibilities of thermal shocking of the fabric. So, the temperature should be increased or decreased in a controlled manner. This controlling is done by heat exchanger. Actually it is an indirect heater. During the circulation of dye bath liquor, the liquor passes through the heat exchanger. A heat exchanger is a device built for efficient heat transfer from one medium to another, whether the media are separated by a solid wall so that they never mix, or the media are in direct contact. Rate Of Heat Exchange IS Proportional To Temp Difference Between Hot Fluid And Cold Fluid *Counter Flow * Parallel Flow


Mechanism of Heat-exchanger: Heat-exchanger consists of no. of tubes surrounded by a shell body. Two fluids of different temperature flow through the heat exchanger. The fluids can be either gas or liquid on either the shell side or the tube side. One flows through the tube other flows through the shell. The temperature of the two fluids is different, so transfer of heat occurs from one fluid to another through shell. The fluids which flow through the tubes come in and pass out from the heat-exchanger on the same side. On the other hand the fluid used in shell comes in and pass out from the different side of the shell. Theory of Application of Heat exchanger: Two fluids, of different starting temperatures, flow through the heat exchanger. One flows through the tubes (the tube side) and the other flows outside the tubes but inside the shell (the shell side). Heat is transferred from one fluid to the other through the tube walls, either from tube side to shell side or vice versa. The fluids can be either liquid or gases on either the shell or the tube side. In order to transfer heat efficiently, a large heat transfer area should be used, so there are many tubes. In this way, waste heat can be put to use. This is a great way to conserve energy. Heat exchanger control pointsSteam Pressure 7 Bar (101.5 PSI) Cooling Water Temperature 25 ⁰C At 3 Bar Max Heating 140 ⁰ C (HTHP) Cool Down Temp 85 ⁰C (HTHP) Filter: During the treatment of fabric in the machine, lots of lose fiber is produced from the fabric. To eliminate these lose fibers, filter is used. It also reduces the lose fibers loads from the fabric. If they lose fibers are not eliminated, then the running of fabric is disturbed & entanglement can be occurred. Fig.: Filter ComponentsFilter Service Door Filtration Section


Filter TypeStainless Steel Sieve Fabric And Steel Sieve Filter ChangeFilters Needed To Be Changed To Maintain The Accurate Nozzle Pressure To Supply Filtered Liquid To Heat Exchanger Time of ChangeAfter Enzyme Wash After Dyeing Bath Drain After Rinsing Features of Filter: The filter eliminates the loose fibres in the dye bath,consequently it reduces the loose fibre loads on the fabric. Changing and cleaning the filters is sometimes forgotten, with the result that the dyeing machine's nozzle pressure decreases, with the effect that running is disturbed and tangles can occur.

automatic self cleaning filter systemNo cleaning of filter. No pressure variation in the nozzles due to lint buildup due to automatic regulation system. No lint on fabric due to 100 % filtration of the circulation liquor. Additional Tank: Additional tank is used forColor dosing Soda dosing Salt dissolving Auxiliaries injection Chemical dosing Ways of liquor flow from additional tank: Two waysInjection Dosing Linear dosing Progressive dosing Decreassive dosing

Progressive dosing

Decreassive dosing


Liquor circulation system: During the treatment of fabric, the liquor is circulated throughout the machine. At first, the required amount of liquor is taken in the main tank. Then the liquor goes to the filter through pump and then it goes to the heat-exchanger. From the heat-exchanger, the liquor goes to the main tank through nozzle. The schematic diagram of liquor circulation system is given below-


Figure: Liquor circulation system Function of dissolution pump: Dissolution pump makes the chemical concentration (salt, soda, dye, auxiliaries) low before passing it to the main tank. This concentration is reduced in 1:4 ratios (liquor from additional tank: liquor from main tank). As a result rate of chemical dosing become slow which gives better fixation. Thus better color yield and even dyeing can obtain.

Remark &Conclusion: We have seen that in dyeing different production parameters like temperature, time, PH, M:L ratio etc. are strictly followed. Sometimes the original dyeing process may not be found according to dyeing curve as they produce some complicated shade. One thing is clearly noticeable that production manager and officers are committed to try their best for reducing production time. FINISHING The final processing of the fabric to increase the natural properties or attractiveness before the fabric is cut into apparel or made into any articles of textiles is called finishing. The finishing process depends on the properties required in the fabric with respect to its use. Objective of finishing To improve the attractiveness and service ability of textile material. To accestiate or inhabit some natural characteristics on textile materials,(such as softening , stiffing , delusture , etc) To impact new characteristics/properties to the textile materials(such as durable press, flame retardant) To increase life & durability of the textile material. To set the fabric, so that it can be maintaining its shape and structure. E.T.C Types of Finishing

Dewatering Machine Company: France. Capacity: 3 tones/shift. Function of dewatering m/c: -Reduce water content -Apply chemicals -Apply overfeed to give some compaction -Open the fabric from the rope form Working principle of Dewatering: After completing the dyeing process from the dyeing m/c then the fabrics are ready for dewatering. In de-watering m/c tubular fabrics are mainly processed. There is a magnetic sensor which scene the twist of the fabric and its direction and turn the fabric in opposite direction to remove twist automatically. Here dewatering is performed De-watering is the process to remove the water from the fabric completely by squeezing and it is done by the padder. A suitable expander is used before the fabric is passed through the nip of the padders, which expands the fabric flat wise and adjust the width. The expander width is adjusted as S/J- 20%, PK-25%, Int.-35%, Lacoste-40% wider than the required width. There is a pair of rubber coated padder, where water is removed from fabric when passed through the nip of it. Normally squeezer contain single or double padders where, - One for removing water and - Other for applying finishing chemicals such as softener. But this finishing is done only for the tubular fabric. Open widths knitted fabrics are applied finishing treatment later in stenter. Here present the compressor which given compress air to form ballooning before passing through the padder. This balloon remove crease mark but not form the maximum balloon otherwise shrinkage increase SLITTING MACHINE Slitting Machine specification:

Fig: Slitting m/c

Slitting: Slitting is a process that is applied for cutting the tubular fabric through the intended break Wales line on lengthwise direction prior to stenter processing.

Machine parts: Rotary blade: To cut the fabric through break Wales line. Ring: To help cutting. Guide Roller: To guide the fabric to plaiting. Plaiting: To plait the fabric. Sensor: Sense for cutting through break Wales line. Working principle: The slitting m/c has 4 units - initial squeezer, de-twisting, slitter and padder. After dyeing completed and falling of water from fabric the fabric is fed in slitting m/c. So it is necessary to remove some water initially for the case of further processing in this m/c. The initial squeezer does this work. The de-twisting unit removes twists that may present in tubular rope form fabric. This unit has 3 de-twisting rollers, one rotation drum and 2 feeler rollers with sensors. By these rollers it detects twist in fabric and removes by rotating rope fabric in opposite direction. Before slitting there is a blower which blows air to open the tubular fabric & makes it easy to pass over cigger. The cigger can be extended in circumference and opens the tubular fabric in full circumference. Slitting is done by using open mark detecting golden eye by around knife. Then the fabric passes through the padder where washing or chemical treatment is done. Squeezer is used to remove 60-70% of water. After removing water width is controlled by stretcher and fabric is delivered by folding device. Operational parameter:


-Set the padder pressure as required (3-7bar) -Set the speed as much as possible (30-80m/min). Function of the Machine: Used to remove excess water after pretreatment and dyeing. To slit the tube fabric by the knife for opening of the fabric and ready for stentering. Delivered fabric increase free state. Before squeezing balloon is formed with the help of compressed air passing by a nozzle or air sprayer. It can control the diameter of fabric and GSM and shrinkage by over feeding mechanism.

The boiler used for producing steam in GKL is Cochran boiler which is a fire tube type boiler. This produced steam is supplied by the steam line in different section. Simple vertical boiler of fire tube type is mainly used in small plant requiring small quantity of steam and where floor area is limited. Classification of boilers: Fire – tube boiler( gas ) : Low pressure , low running cost , less chance of busting but greater risk of damage. Water – tube boiler: High pressures, high running cost high chance of bursting & don’t damage the whole boiler. As this factory used fire tube boilers and its description is given below. In boiler house, steam is produced at high temperature and pressure. This produced steam is supplied by the steam line in different section. Uses: Steam use for – Power generation ( steam engine / turbine ) . Processing in industries ( dyeing & finishing mill , sugar mill , paper mill etc. ). Heating purposes ( houses , offices , hospitals etc in cold countries ). Hot water supply. Essentials of a good boiler: Required pressure and quality at minimum fuel . Initial installation and maintenance cost low . Parts approachable for repairs .


Quick starting capacity . Conform to the safely regulations of boiler act . Working principle: The gas is fed through the front side to the furnace where fire created by electric spark. The blower move the fire into the flue pipe by compress air and then the flue gases enter through the combustion chamber which is lined with fire bricks on the outer wall of boiler. The hot gases passing through the horizontal smoke tubes give their heat to the water and convert water into steam. This steam gets accumulated in the upper portion of shell from where it can be supplied to the users. Finally, the flue gases are discharged to the atmosphere through the smoke box and chimney.

WATER TREATMENT The back wash & regeneration process: The back wash process to clean the vessel no-1,2 & 3. The back wash process should be done after 8-12hrs. After 40-48 hrs later the regeneration process should be done. It should be done after back wash process. After back wash the common salt dissolved with water in to the STT (salt saturated tank) the solution of common salt is ringing the resin by the injector. The use of 18% salt in the total solution. (Suppose, 5000 lit of solution the amount of salt 600kg). The resin is activated by the salt rising. Here used cationic resin (NaHSO3). If the PH of the water increase or decrease it should be control by the dosing chemical (Sodium Hypochlorite) from the chemical tank.
