Industrial Attachment at DK Textile Mills Ltd Introduction By means of practical knowledge it’s not possible to apply the theoretical knowledge in the practical field. For any technical education, practical experience is almost equal important in association with the theoretical knowledge. The industrial attachment is the process, which builds understanding, skills and attitude of the performer, which improves his knowledge in boosting productivity and services. University education provides us vast theoretical knowledge as well as more practical attachment, in despite of all these industrial attachment helps us to be familiar with technical support of modern machinery, skill ness about various processing stages. It also provides us sufficient practical knowledge about production management, work study, efficiency, industrial management, purchasing, utility and maintenance of machinery and their operation techniques etc. the above mentioned cannot be achieved successfully by means of theoretical knowledge only. This is why it should be accomplished with practical knowledge in which it is based on. Industrial attachment makes us reliable to be accustomed with the industrial atmosphere and improve courage and inspiration to take self responsibility. 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 DK Textile Mills Ltd , which is a 100% export-oriented composite Industry. It has well planned & equipped fabric dyeing-finishing and garments units in addition to facilitate knitting and knitwear manufacturing.

Any circular knitted fabric is composed of row after row of intermeshed loops. Different types of fabric are made of different

method of intermeshing the loops. The gross dimension of knitted fabric is simply a reflection of any shape & size of individual loops. There are several key variables in the production which affect the average shape & size of the loops. After knitting the greige fabric is dyed to required shade & finished to required weight & width.

Straight knife Band knife Round knife Die knife Notcher Drill

3. Computerized    

Knife Laser water knife Plasma torc Spreading Spreading means the smooth laying out of the fabric in superimposed layers of specific length. The cutting marker paper is laid in the top of the fabric layers. The maximum width of the cutting marker constrained by the usable width of the fabric. During spreading number of the plies should be not more than three hundreds. The number of lay depends on the thickness of the fabric and the height of the knife. In DK TEXTILE industry use straight method for spreading .It is the most common method for Bangladeshi garments. Straight method: Every ply is placed according to the marker length. It is most common of the garments are used this type of ply.

Features of Straight knife: 1. Possible to cut pattern pieces directly from the fabric lays. 2. Could be used to cut for higher depth of fabric. 3. High cutting speed. 4. Sharp and heavy corners can be cut. 5. Blade could be sharpened by attached grinding facilities. 6. Blade height 10 to 33cm. 7 .Blade stroke 2.5cm to 4.5cm. .

2 Over lock m/c Overlook stitching was invented by the Merrow Machine Company in 1881. An overlook stitch sews over the edge of one or two pieces of cloth for edging, hemming or seaming. Usually an overlook sewing machine will cut the edges of the cloth as they are fed through (such machines are called ‘sergers’), though some are made without cutters. The inclusion of automated cutters allows overlook machines to create finished seams easily and quickly. Properties:  5 thread  4 tensioner  2 knifes (up / down)  2 needle for 5 thread  1 needle for 3 thread  3 looper for 5 thread  2 looper for 3 thread Applications:  Over lock stitch 3 Bar tack m/c Bar tacking is accomplished by sewing a very tight zigzag stitch across the width of the material. In some cases, the manufacturer may go over the bar tacking again, causing the stitch to have an x-like form. Usually, very strong threads are chosen for bar tacking so that they will stand up to high pressure. When done Applications:  To created barack stitches in garments. Bar tacking is a specialized sewing stitch designed to provide Immense tensile strength to the garment or equipment it is used on. Bar tacking is commonly used on backpacks, tents, tactical gear, and other heavy wear sewn items where normally sewn stitches might give way at a crucial moment. In general, bar tacking is a sign of good quality, although the rest of the product should always be looked over carefully as well. When a sewing pattern calls for bar tacking, it indicates that the designer feels that section of the pattern is a critical area that needs extra reinforcement and following areas it can used.       

Chain stitch is an ancient craft - examples of surviving Chinese chain stitch embroidery worked in silk thread have been dated to the Warring States period (5th-3rd century BC). Handmade chain stitch embroidery does not require that the needle pass through more than one layer of fabric. For this reason the stitch is an effective surface embellishment near seams on finished fabric. Because chain stitches can form flowing, curved lines, they are used in many surface embroidery styles that mimic "drawing" in thread Properties:  2 needle  2 looper  4 thread  4 tensioner (back 2/front 2) Applications:  Back rise stitch  Back yoke stitch  Top sin ¼ stitch

Hard worker Order Collection

Order Collection is the main theme of a garments factory. DK TEXTILE LTD.Handle this sector. They collect order from different types of buying house. Sometimes the Managing Director visited different country as like France, Germany, and England to collect order for their company. Negotiation with buyer A successful negotiation outcome does not generally occur through luck, but by following a clear process. The process reflects the different levels of knowledge of the subject of negotiation, various parties and the way they communicate at various stages in the negotiation. The following is an outline of steps essential to effective negotiation: Preparation Effective preparation is also vital to successful communication. It is essential that the buyer also has identified the maximum and minimum positions that she will accept for a range of factors including:  product price  order size  Lead- time. Offer The buyer and supplier can make specific proposals to set the boundaries of the negotiation. Counter and revised offers

This is the real bargaining where elements of the order, such as number of units, product details, lead-time and so on are being decided in the context of an overall cost price the buyer should make firm proposals.

Another product package Types of sample:

• Fit Sample- The sample which is made by following only the measurement chart. Then the sample we get that is called fit sample. For this type of sample buyer only check the measurement of the apparel nothing else. • Proto type sample- Actual fabric and the accessories used to make this sample then it is send to the buyer. It is only of one size like “M”. • Size set sample- When all size of sample (small, medium, large) are included in a set those sample is called is size set sample. • Production Sample- During production some of the sample garments collect from the production line then it send to the buyer these are called production sample. • Shipment Sample- After final inspection when we shipment the goods to buyer destination two pieces sample should be send to buyer air as advanced this sample are called shipment sample. •

Approved sample- The sample which is approved by buyer.

• Sample garment- The garment which represent the huge quantity of garment that is called sample garment. Marker making: Marker is a thin paper where all parts of a (or more than one) style drawn by placing pattern by pencil and then it place upon the lay and cut along the drawing line is called marker. The process of marker making is called marker making. The method is available in DK TEXTILE industry• Manual method DK TEXTILE used only Manual method to make a marker. Awareness during Marker Making:

       

Pattern alignment Pattern direction Parts missing Mismatched checked/ stripes Over lapping Marker too wide than fabric Poor Or double line marking When pattern pieces are laid down on the layer of fabric, the grain line should be parallel to the line of the warp in a knit fabric where pattern pieces are laid across the layer’s the line is kept parallel to course Problems of marker making:

There are many problems behind this. They are as follow: 1. The nature of the fabric and desired shape and style of the garments. 2. The requirements of quality of cutting. 3. The requirements of production planning L/C (Letter of Credit) Various types of L.C. are present in business system. Some recognized processes are

1) Master L/C 2) Back to Back L/C 3) Sight L/C 4.) Revocable L/C 5.) Irrevocable L/C

(Note: in Bangladesh sight L/ c OR irrevocable L/ c is mainly used)

 Master L/C: In this trade initially cash money is not used. L. c is the main process for buying & selling. When a business deal is made for buying & selling between buyer & merchandiser then the buyer gives permission to his bank to open an L.C. of approx amount & send it to merchandiser’s bank. Then this bank informed to merchandiser that an L.C. is accepted. This l .c is called MASTER L.C. 

Back to Back L/C: MERCHANDISER takes decision about the manufacturer for collecting raw materials .when merchandiser choose supplier then he tell the supplier to

send a pro-forma invoice. After getting p .I. merchandiser tell to his bank to open an l .c send to the supplier’s bank. This l. c is opened from mother l .c which is given to merchandiser. This l .c is called back to back or b to b l.c. ďƒ˜ Sight L/C: Sight L/C means that payment is made immediately to the beneficiary/seller/exporter upon presentation of the correct documents in the required time frame.

Production Planning, Sequence & OperationSource of Raw Materials: Grey fabric is collected from Dk Textile Ltd Dyes & Chemicals are imported from Germany, Switzerland, Singapore, Turkey, India and China etc. Remarks: Price & Monthly consumption are unavailable. Basic procedure of Production Planning and Control: A planned work brings success. Without planning nothing is complete within the required time. So planning has its own importance which is intolerable. Planning gives a scheduled task and control completes it successfully. But production planning and control is not an easy task. Its basic working procedure is as followsOrder received by marketing division ↓ Analyzing the orders ↓ Planning for knitting ↓ Planning for dyeing ↓ Planning for finishing the fabric ↓ Planning for garments It is only a basic procedure. It may change according to the type of order. Sometimes the order is placed only for finishing the materials. Then some steps are minimizing for planning.  Taking order from marketing division: Marketing division supplied fabric orders to the planning and control division by a specific format.  Analyzing the orders: After getting the fabric order, this section analyzes the orders according to buyers order quantity, type of orders (i.e. type of fabric, color to be dyed etc.), delivery date etc. This section plans for required quantity of fabric to be knitted (order quantity + 10% of the order quantity), knitting balance, fabric to be dyed, dyeing balance, RFD (ready for delivery), RFD balance, delivery fabric & delivery balance etc.  Planning for knitting: This section plans for knitting production. Following parameters are important for the planning of knitting the fabric –

» Order quantity (required amount of fabric to be knitted) » Type of fabric to be knitted (S/J, rib, interlock) » No of machine to be used » Type of yarn used » Sources of yarn » Fabric GSM, width etc.  Planning for dyeing the fabric: Production planning for dyeing is called “Batch plan”. Batch plan is prepared according to the batch no, fabric construction, color, width, GSM and priority of delivery etc and written in a batch card.  Planning for finishing the fabric: Finishing schedule are same as the dyeing. After dyeing, materials go to the finishing section with the batch plan. Finishing data is written to the batch card and is informed to the planning section. However, this section always forces to all the departments to finish all the work within the delivery time given by the buyers. Thus, it plays a very important role in the success of the company.  Planning for Garments: After the finishing process the finished fabrics are ready for producing garments. For the production of garments this fabric has to passed through some process≈ Laying ≈ Cutting ≈ Sorting ≈ Sewing ≈ Finishing ≈ Packing etc. All this processes are planned according to the shipment schedule. However, the planning section always forces to all the departments to finish all the work within the scheduled time given by the buyers.

There are also two submersible pumps in the deep tubeweel one is 100 ft deep and another is 140 ft deep. The submersible pump transfer raw water in the water tank by creates force. The formation of oxidation of the water by showering with the help of another two pimps in the water tank. Iron content removes by the oxidation. Two circular transfer raw water in the (vessel no-1) Multigrade filter unit. The large size plastic, iron that means solid content are removed in the multigrade filter unit. The water is transferred to the (vessel No-2) Activated carbon filter unit. In the (vessel No-2) Activated carbon unit to remove chlorine that means bad smell. The water then transfer in to the (vessel No-3) softener unit from the activated carbon unit at the presence of cationic resin (Zeolite) is reacted with water to remove the hardness of water. The water is transferred in to the reserve tank from the softener unit. The soft water is supplied from the reserve tank by the 7 Boosting pump in the different section of the factory. 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. A

The capacity of WTP= 60m3/ hr Effluent Treatment Plant Effluent Treatment Plant (ETP) is a plant by which waste water is treated in order to make the waste water environmental friendly. Effluent Treatment makes sure that water releases meet Bangladesh Environmental Association water quality standard. It is very important and essential to keep the environment pollution free. Now a day ETP is the most important term to set a textile industry. Government, Environmental Association and foreign buyers are creating pressure to set ETP in every textile industry. So, to ensure the proper growth of textile sector and pollution free environment every textile industries have to set up an ETP. Details on ETP: There are three effluent treatment plants which are : • Biological treatment plant. Biological treatment plant : This process is mainly build up by using micro-organism. This is Bacteria. Amoeba, and Protozoa. Bacteria are two types, one is Anaerobic & Aerobic. First one is hazardous for our environment and second one is friendly for our environment. In here Bacteria break the bond of harmful chemical by enzyme secretion. As a result harmful chemical converted into environmental friendly. The sludge produces by this process is also used as different functions such as fertilizer, fuel in the brick field. Micro organism is the main raw material for Biological plant: • bacterial • amoeba • protozoa Bacteria : 1. Bacilli 2. Cocci 3. Beggiatoa 4. Spirillum 5. Vitereoeilla Protozoa : • Paramecium caudatum • Euplotes • Coplidium Amoeba : • Rotifiers • Collities

The declining retail sales and the losses shows by big retailer's worldwide and consequent drop in order in the worldwide garment industry proved to be a major challenge to our marketing efforts and strategy. The very fact that in spite of the factors mentioned earlier MTL maintained more or less the sales of last year showing a fall on only 3.32% is a credit to their marketing. In an uncertain world market, MTL doubled their efforts with our design team leading the way; they increased their calls as the customers & looked for ways to add new ones also. Having established a strong relationship with H & M and becoming one of their core suppliers, MTL targeted Europe & Australia also and made in roads there. MTL added new and dynamic designers to the existing team & can proudly say that their spring and autumn collections were hailed as some of the best to be presented. These meetings boosted the confidence of existing buyers and attracted new customers. MTL continued with their strategy to market value added products like dyed fabrics with special finishes. This is reflected in the increase in average price per linear meter. MTL now in a strong position to take on the challenge of WTO in the end of 2004 when quotes will be abolished and only those company's with a reputation for innovative, creativity and reliability and the ones having strong strategic relationships and business alliances will survive and benefit.
