INTRODUCTION:-

Textile technology education is based on industrial ground. Theoretical background is not sufficient so, industrial training is an essential part of study to make a technologist technically sound in this field. Industrial training provides us that opportunity to gather practical knowledge.

Sinha Textile Group is a truly integrated undertaking. The textile division has the capability to offer a complete product range for the export & domestic textile markets. The goal of the textile division is to become the preferred partner for sourcing high quality fabrics & clothing from Bangladesh. With high advanced technology & an emphasis on developing local human resources, the textile division has the potential to make an important contribution to the nation’s growing ready made garments export sector.

The rational behind the existing structure & future expansion of the textile division is to capture value added at each stage of the textile manufacturing process. Despite Bangladesh’s lack of indigenous cotton production capability, STG has leveraged Bangladesh’s labor cost advantage & export competitiveness to maximum level.

BRIEF DESCRIPTION OF TEXTILE:-

The term ‘Textile’ means originally a woven fabric, but textile & the plural textiles are now also applied to fibre, filament & yarn. Natural & manufactured & most products for which these are a particular raw material.

This definition embraces, for example fibre- based products in the following categories: threads, cords, ropes & braids; woven, knitted & non woven fabrics, lace, nets & embroidery; hosiery knitwear & made up apparels; household textiles, soft furnishing & upholstery; carpets & other floor coverings; technical, industrial & engineering textiles include geo textiles & medical textiles.

Some necessary terms in textile processing & production are given below-FIBRE: Textile raw materials generally characterized by fineness, Flexibility & high ratio of length to thickness.

YARN: A product of substantial length & relatively small cross section consisting of fibre(s) and/or filament(s) with or

without twist.

FABRIC: A manufactured assembly of fibres and/or yarns that has substantial surface area in relation to its thickness& sufficient cohesion to give the assembly useful mechanical strength. Common processes of fabricmanufacturing are weaving, knitting & non woven.

a) Weaving: The action of producing fabric by Interlacing of warp & weft threads.b) Knitting: The process of manufacturing of fabricby the intermeshing of loops of yarn.

6

c) Non-woven: The process of producing of fabrics by chemical bonding of fibres.

Hard Winding 0.5% - 1% Hard Waste

Wastage Of Warping Section:-

In the warping section wastage is mainly the left over yarns. This amount is normally 1200mm per package that is almost 6%.

52

Wastage Of Sizing Section:-

In the sizing area wastage comes mainly from the portion of yarn sheet that is being kept as backing after completion of sizing for easy passing of the next beam’s yarn sheet through the sizing machine. So, wastage comes mainly from two portion. That is from unsized yarn sheet & sized yarn sheet.

-For Yarn dyed beam the amount of waste is approx. 20m.-For Grey beam the amount of waste is approx. 30m.

Wastage Of Weaving Unit:-

In the weaving unit waste comes from warp yarn & weft yarn. At first, during running of loom some portion of wastage is there due to different fabric faults. Then after weaving some fabric is being kept as backing, that portion is wasted. Weft yarn that goes over filling length, that portion is cut & this amount is waste portion. Due to friction of warp yarn with heald eye & reed some fibre flies, that is wastage. During every weaving operation 12 yarns of the warp length is waste. So some amount of wastage of weaving unit is given below from practical observation.

- During running of weaving of fabric 10 m warp yarn wastage with some portion of weft yarn.- After completing the weaving approximately 3m-4m warp yarn wastage that remains for backing.- 80 mm of each weft yarn is waste that is over the filling length. - Except these 0.2% other wastage are involved as fly and as hard waste during every filling stop.

53

Wastage Of Processing Unit:-

In the processing unit the amount of waste is given depending on the liquid waste that means water & chemical wastage. The amount of waste is given here for certain length of fabric processing & this amount is very high because there is no recovery system is available.

Comments:-

From the above information we see that the amount of wastage varies from section to section. We must should develop the accuracy of different process to reduce the amount of wastage. In case of processing we should introduce a system that may help to recover few portion of water & chemical so that the amount of this huge percentage of waste can be minimized.

54

INSPECTION OF FABRIC BY 4 POINT SYSTEM:-

Fabric Inspection:-

The inspection of fabric is a procedure by which the defects of fabric are identified and fabric is classified according to degree or intensity of defects.

In Sinha Textile Group the fabric inspection is done by 4 point inspection system. The details of it given below.

Yarn fault Penalty points

Thick/thin The yarn is thick/thin than normal yarn

ABOUT RESEARCH & DEVELOPMENT:-

The word “Research” is closely related with the way of wearisome to invent something or giving a new technique as solution of any requirement. On the other hand “Development” stands for the physical appearance of any researched or planned agenda. For this reason the globe of “Research & Development” is based on both speculative job as well as convenient. In the textile sector department of “Research & Development” i.e. R&D is very much essential. Specifically for an industry which is running with an complete industrial park. When an industry can stand up with all the projects like spinning, yarn dyeing, weaving & processing together in a region, then it is very much logical to construct a department like R&D.

Research & Development department mainly works for development, most of the time. Very few time the works of research is being done whenever it is requisite. In the big woven composite factories this department is subjected as “ Gate Of Order” of the products. This title is not a fiction, R&D department means it beyond doubt. This department has it’s own way to ensue the regular production of an industry. As a department it is diminutive but it’s effect is prominent all over in an industry.

In the vicinity of Sinha Textile Group, R&D department is playing as a imperative role which helps the industry to run it’s yearly production effortlessly on the decisive way of business & trade of world.

During my industrial training stage, I have tried my level best to comprehend all the works & also the way of implementation those works of the research & development department. The information related to this department & it’s job are discussed critically towards the end.

DETAILS OF R&D WORK:-68

Previously the basic flow chart of R&D had been discussed. Now this is the time to describe every steps broadly, those are critically followed during the development period of sample in the Research & Development department. Getting Swatch From Buyer For Duplication:-

The work of research & development section starts by getting order letter & swatch or CAD from buyer for duplication. The order letter comes through marketing section after getting the signature of the Director(technical). Following the order letter & swatch or CAD the next step is decided. Normally when a fabric order comes then all the necessary instructions that is required, are being given by buyers.

Analysis:-

Normally after getting the swatch, the work of analysis is being done. The fabric analysis mainly includes following works-

- Ends per inch measurement.- Picks per inch measurement.- Warp count measurement- Weft count measurement.- Weight of fabric measurement.- Design, Lifting plan & Drafting plan measurement in

case of designed fabric.- Pattern making by analysis of the standard in case of

yarn dyed fabric.- Yarn cones, Cone length, Amount of yarn

measurement in total as well as of each colour.- Reed count, Reed space measurement.- Total ends measurement according to fabric width.- Colour matching after dyeing with standard.- Pattern matching at the starting of weaving of fabric.

69

Planning For Sampling:-

After completion of analysis it is necessary to develop a plan for sampling. In the R&D section the development work starts normally with desk loom or handloom sample. In the section there is one desk loom available which is operated by an weaver. On the other hand one handloom is available which is operated manually in total. To develop a desk loom or handloom sample it is required to make an accurate pattern of fabric. Normally yarn dyed fabrics are developed regularly in the desk loom or handloom. So at first, planning for sampling may start with desk loom. After producing a handloom swatch from the analyzed information, that swatch is being submitted to the related buyers through merchandises for pattern & colour approval. If buyer approves then R&D makes the program to develop 150m fabric at first then 650 m fabric for LF & CS sample. This is for normal yarn dyed development. For solid dyed fabric the planning for development mainly depends on the quantity requirement of buyer. For both cases, first of all papers are being made from analysis data & then the programs for yarn requisition from SRSL, for yarn dyeing (in case of yarn dyed fabric),for warping & sizing, for weaving & finally for processing are supplied to complete the work.

Yarn Ordering:-

After planning of sample it is necessary to order the required amount of yarn for development of the sample. From analysis we can measure the total amount of yarn that is required for a development. That much amount of yarn have to take from Sinha Rotor Spinning Limited. So, in the yarn requisition paper of R&D every information related to yarn order like name of buyer, fabric construction, the count of yarn, amount of yarn, type of yarn etc have to write & send the paper taking the signature of production officer & manager to SRSL. In that paper we have to inform also in which section the grey yarn shall be provided. In this way we

70

can order the yarn for a particular development. In the R&D section we maintain a record book where we keep the reference number for a particular yarn order. In future when we need that yarn again, we just follow the reference number & give that number to store or SRSL to get the yarn.

Yarn Dyeing & Random Program:-

This step comes in case of producing yarn dyed fabric. The ordered yarn directly goes to the yarn dyeing section for dyeing purpose. R&D section informs the yarn dyeing section all the necessary information related to yarn dyeing like the shade of colours, the quantity of each colour to be dyed, warp way colours & weft way colours, number of cones of each colour for random program as well as the cone length. Following these instructions yarn dyeing & random program is being done. When the yarn dyeing section receives the order of R&D section then they make a time & action plan(TAP) & send this to R&D. Following that plan we get informed when we can receive the dyed & random yarn from yarn dyeing section.

Warping:-

The purpose of warping is to arrange a convenient number of warp yarns so that they can be collected on a single warper’s beam.There are two types of warping. These are-

- Beam Warping Or Direct Warping.- Sectional Warping.

Now for the solid dyed fabric after yarn ordering when we receive the required quantity of yarn then the next step is direct warping.On the other hand for the yarn dyed fabric after completion of dyeing & random of yarn we have to do the sectional warping or beam warping(less than 15% coloured yarn of total).

71

So we can say that the beam warping or the direct warping is used for long runs of grey fabrics & simple patterns where the amount of coloured yarn involved is less than about 15% of the total.On the other hand sectional warping is used for short runs, especially of fancy patterned where the amount of coloured yarn is more than about 15% of the total.

Now we have to know how the grey yarn or dyed yarn will run for warping. During the analysis & planning for sampling period we make a paper that is supplied taking the approval of manager & GM to warping & sizing section as well as to the weaving section. There the pattern is given & following the pattern the warping people carry the warping process. Here we have maximum creel capacity of 560 for sectional warping & 640 for direct warping.In case of direct warping R&D section informs the cone length, no. of beams according to the fabric requirement which have to be produced, through a paper.It takes 3-4 hours to complete warping for a sample. So after completion of warping we are getting the warper’s beam which is ready for sizing now.

Sizing:-

The process of application of size solution to yarns by immersion into the solution & squeezing, which is followed by drying to make the warp yarn more suitable for wearing is known as sizing.The primary purpose of warp sizing is to produce a warp, which will suffer the least damage in wearing. In some cases it is also used to modify the characters of the yarn so as have as effect on the fabric weight, hand feel. But sizing is mainly done to make the warp yarn stronger, smooth & better lubricated.In the steps of producing the sample fabric the sizing is a vital step, which is done after producing the warper’s beam. In the sizing unit of Sinha Textile Group the chemicals used for sizing are here,

-Finnfix 30(For Finer Yarn Count Like Above 26’s)

72

-Finnfix 150(For Coarser Yarn Count Like 8’s-24’s)-Finnfix 700(For Coarser Yarn Count Like 8’s-24’s)-Trifix (Wax)

Normal recipe for sizing of coarser yarn count is--Water--- 500 Litres-Finnfix 700--- 20 Kg-Finnfix 150--- 13 Kg-Trifix (Wax)--- 02 Kg-Chemical Coating Time--- 25 min.-Sizing Time--- 02 hours(For 5000m Length at 35-40m/min speed)

In this way sizing of the warp yarn is done & finally we are getting the weaver’s beam of the ordered sample.

Weaving:-

After getting the sized weaver’s beam at first that beam is being received by the weaving unit. Then firstly drawing-in or Knotting is done following the pattern made by R&D section. After completing the drawing-in then denting is done. Finally according to the design weaving of the fabric starts. For weaving the required weft yarn is being supplied by store(in case of grey fabric) or by the yarn dyeing unit(in case of yarn dyed fabric). In STG there are two types of loom available. One is Rapier & the other I Air Jet loom. So in both type of loom it is possible to produce the fabric. In this way after few days we get the required amount of fabric in grey condition from weaving unit. Processing & Finishing:-

Processing actually stands for wet processing of the grey fabric that makes the fabric suitable for use. Processing of the grey fabric involves the steps like singeing, desizing, scouring, bleaching, mercerizing, dyeing (in case of demand of coloured fabric) or printing (in case of demand of printed fabric) & finally finishing.

73

Singeing of grey cloth or yarn is performed to remove all protruding fibers imparting external appearance of ready articles and impeding further treatment. Almost all fabrics are singed except for those that are subjected to napping, pile fabrics, gauze and terry fabrics.

Desizing is the process by which sizing material is removed from the surface of the fabric. These sizing materials are starch, polyvinyl alcohol, carboxy methyl cellulose, polyamides, poly-acrylates etc.

The example of using singeing and desizing or singeing/desizing is as follows:

All cotton color fabric (singeing and desizing) All cotton color peach finish (desizing only) Yarn dyed fabric and PC/CVC fabric (singeing and desizing)

PC/CVC/yarn dyed peach finish fabric (desizing only)

The main purpose of scouring textile material is to remove natural as well as added impurities of essentially hydrophobic character as completely as possible and leave the material in a highly absorptive condition without undergoing chemical or physical damage significantly and also to make the goods suitable for removing the natural coloring matter of the cotton during the subsequent bleaching process.In the bleaching process the colored material is destroyed and thus to confer a pure white appearance to the fabric. Bleaching should also decolorize or remove any residual impurities left by scouring.

Mercerizing is the process that increases the tensile strength, dimensional stability & luster of the fabric that initiates to further increase in the dye affinity of fibre.

The dyeing of textiles is usually understood to mean giving them a color, which is of comparative performance. This implies it should

74

not be possible to wash the color out easily in laundering, nor should it fade rapidly when exposed to light. The condition of performance distinguishes dyeing from tinting (When the material is given a color which is very easily removed with a detergent and water). Yarns are tinted occasionally so that different counts and quantities can be identified during weaving or knitting or any operation, which precedes dyeing.

Printing can be considered as a technique of localized dyeing where in the coloring material is applied only to restricted areas. The main objective in textile printing is the production of attractive designs with well defined boundaries made by the artistic arrangement of a motif or motifs in one or more colors.

Bleached dyed and printed fabrics are subjected to certain processes known as finishing processes in order to alter their appearance, feel and sale value before sending them to the market for sale. Depending to the end use of the materials, various finishing processes are carried out. These may be mechanical or chemical processes and effects produced may be temporary, semi permanent or permanent. They may involve mechanical deposition or chemical reaction with the fabric substance or both.

So, we can see that each & every steps of processing are equally important for grey goods to be a finished product that can be used by people. In case of grey goods that will be solid dyed further, must be subjected to all the processes described above. In case of yarn dyed grey fabric the processes that have to be followed are singeing & desizing, washing & finally finishing in the stenter machine & in the sanforise machine.

In this way we can complete the processing of the fabric within few hours.

75

Testing:-

Testing of the finished fabric is done mainly to identify the final performance of the fabric. This is also done to clarify that either the fabric is ready to fulfill the demand of the buyer or not. The testing of the finished fabric is carried out in the laboratory of Sinha Dyeing & Finishing Limited. Some very useful tests are done in the laboratory. These are like-

- Testing Of Stretch, Growth & Recovery.- Shrinkage.- Tensile Strength.- Tearing Strength.- Colour Fastness To Wash.- Colour Fastness To Light.- Colour Fastness To Rubbing.- Shade Sorting.- Listing & Tailing Of Dyed Fabric etc.

Many other tests are done in case of requirement of buyers but these are the common tests that are done in all the cases.

Send The Fabric To Buyer For Approval:-

After testing if we see that the fabric’s performance is appropriate, then we send the fabric for buyer’s approval through merchandiser. Rejection Or Approve For Bulk Production:-

If buyer see that the produced fabrics are satisfying their demand then they may approve it. On the other hand if we cant satisfy them the order will be rejected. But in most of the cases R&D satisfies the buyers need & carry on the bulk production.

In this way R&D department regularly doing their task to get the bulk order in every season & satisfy the buyer. To do the work all these steps comes in the way of research & development

76

REQUIRED FORMULAS FOR R&D WORK:-

During the work of Research & Development we have to do lot of calculations in every steps. There are some formulas, which we followed to do the calculations. These formulas are given below-

Normally when buyers send CAD then they give the construction & weave of the fabric. Otherwise in case of their supplied fabric swatch, we have to identify the construction & weave. The calculation that I am representing is based on CAD.

Formula to calculate the coloured yarns in warp direction

Length in scale of that coloured portion(cm) No. of colored yarn = * EPI

25.4

Formula to calculate the coloured yarns in weft direction

Length in scale of that coloured portion(cm)No. of coloured yarn = * PPI

25.4

Formula to calculate the total ends of fabric

Total Ends = EPI * Required width of fabric.

Formula to calculate the no. of section for sectional warping

Total no. of section = Total Ends/ Total no. of cone of warp yarn

Formula to calculate the cone length

Cone length = Required warp length * Total no. of section.

Formula to calculate the reed count

77

STG followed Reed count in stock port system, EPI* 0.9(Considering10% Shrinkage)Reed count = * 2 Ends per dent

Formula to calculate the reed space

Reed space = Total Ends / EPI*0.9(considering 10% shrinkage)

Formula to calculate no. of cones in case of direct warping

No. of cones = Total Ends / No. of warper’s beam

Formula to calculate cone length in case of direct warping

Cone length = No. of warper’s beam * Warp length

Formula to calculate quantity of yarn for yarn dyed fabric For warp yarn, No. of cones of the colour * Cone Length * .5905

Yarn quantity for specific colour= (Kg) Count of yarn * 1000

For weft yarn,

Yarn quantity for specific colour = Quantity of warp yarn * 60%

Formula to calculate quantity of yarn for solid dyed fabric

EPI or PPI * Warp Length * Fabric Width * .5905Yarn quantity(Kg) =

Count of yarn * 100

78

REQUIRED FORMATS FOR R&D WORKS:-

I have earned some knowledge about the quality management system of different sections of the industry.

I have identified the process sequence of different units that gives me the better idea about running of a program.

I got the information related to amount of wastage of different unit that will help me to calculate the benefit & loss of any project that can be run.

I have developed my knowledge in a very important sector like research & development that will help me to enrich my working experience in all area of textile in spite of a specific machine or section.

Different types of fabric of diverse design & construction are being analyzed by me that given me much better idea about manufacturing of individual types of clothing.

Communication with different buyers & merchandiser helped me to develop my personal skills & self-confidence.

Furthermore I achieved some practical knowledge about every steps related to production of a woven fabric that will facilitate me to develop my experience more in this field.

CONCLUSION:-

For every person who is fresher in the field of textile, industrial training works like learning route. This course given me the opportunity to move liberally in every section of the industry to learn the industrial work & follow the process sequence virtually. From my two months observation of the industry along with research & development section specially, I can say that in the weaving sector this industry has very strong possibility because the industry is running with all modern machineries & very knowledgeable persons are working all the time with their maximum oomph. I just think the capacity of the industry should be developed with the amount of order the industry is being taking.

In the production floor the commanding power of the officers, compliance, administration rules everything are appealing. I hope that this industrial training will help me a lot to work in the future period wherever I want to develop my career. Finally wishing the best prospect of both the industry & myself I want to conclude.

Thank you.
