DESIGNING

Designing department acts as the heart and soul of the whole process of fabric making. This department receives feedback from the market and after analyzing various factors the designs are developed. There are mainly two seasons i.e. Fall/Winter and Spring/Summer. New designs according to the market trends are developed along with improving some of the old designs. The procedure of designing is briefly explained here.

> Basic design / Pattern development> Design pattern selection> Master cards> Feeler manufacturing> Production plan> MasterCard delivery> Feedback

New shades are developed by HOD (Designing) in tune with the current trends and count, blend & twist / inch are also decided by HOD.

Basic design development:

The inputs for this procedure are blend composition, twist, count & shade. As per the end product required, the loom setting(ends/inch X picks/inch X reed width in inches on loom) is decided. To establish a basic design, feeler sample is made & after approval from sales, design pattern are developed and finished accordingly.

Design Pattern Section:

The cut samples from blanket sample are shown to VP(Sales) & HOD (Designing) and selected according to trend.

Master card :

Master cards of approved design are made. While preparing Master cards, draft & peg plans are made according to design on a graph card.

Feeler manufacturing

For feeler manufacturing yarn requirement and yarns are taken from store and if single yarn is available, it is made 1,2, or 3 ply according to the requirement. If yarn is not available, arrangement for yarn manufacturing is made and piece ticket is issued. After finishing, feelers are checked for fel and finish and if rejected, it is kept separate and sold separately.

Page 7: OCM

Production Plan:

The production plan is received from sales for regular ranges according to market requirements and the whole process is made according to this production plan.

Master card delivery :

The master card made is checked with the folder and duly signed by HOD. After this the master card is sent to Q.C.Lab sends the master card to PPC (Production Planning & Control).

Page 8: OCM

PRODUCTION PLANNING & CONTROL

If designing can be considered as the heart & soul of the Mill, the production planning & control dept acts as the nervous system of the Mill. This deptt plans the production and issues the various plans to different departments and also controls the whole production process.

This department works under the below given procedure.

> Estimation of raw material> Design wise manufacturing plan> Yarn Spinning Order> Monitoring yarn stock/indents> Issuing warp /weft piece tickets to weaving> Monitoring fabric production> Reports for sales plan Vs production

Estimation of raw material:

The tentative planning for winter and summer seasons is made on the basis ol average weight per metre and basic blend composition for each quality. The tentative raw material requirement is also made with 7 months for winter and 5 months for summer.

Design wise manufacturing plan:

The plan is received for :Civil from Sales Export from export

The actual production plan is divided into months according to monthly capacity and given targets.

Yarn Spinning order :

The master cards from Q.C. Lab helps in issuing indents to Spinning, Recombing & Dye House. The process completion dates are put on the indents, which helps the PPC to monitor the process.

Monitoring yarn stock/indents

The yarn stock and the position of indents is monitored carefully so that the target dates can be achieved and no process go out of control. Daily status of production is checked at various stages for this purpose.

Page 9: OCM

Issue of warp/weft piece tickets to weaving:

The warp and weft piece tickets are issued to weaving which contains the full plan to weave the fabric. The colour, pattern and design are contained in the piece tickets and the operator of loom understands the details and manufacture the fabric accordingly.

Monitoring fabric production :

The fabric production stage is monitored so that the target dates are achieved in addition to the maintaining of quality and fool proof production.

Reports for sales plan Vs production:

A fortnightly report is made which shows the production and sales plan and thus shows the surplus or deficit production which helps in controlling the production as well as planning for future.

DYE HOUSE

The Dye House unit is a major operational unit in the company. The product is given its proper and required shade in the Dye House. The raw wool received as raw material is of white or natural colour and dye house dyes the wool into the required shade according to the market demand and the customer's order.

The detailed procedure followed at the Dye House is show in the figure. Basically three types of products are dyed in Dye House. These are :

> Top dyeing> Yarn dyeing> Fabric Piece dyeing

Top dyeing :

The tops are dyed and the below given procedure is followed :

Material and Shade Checking :

The material i.e. the top is checked after dyeing and the shade is matched. The sample dyeing is also done for dyeing and the results are matched with the required shaded sample.

Hydroextraction :

Hydroextraction is done by Spinning the dyed material at high speed in a big cylindrical machine to dry the material as well as to do away with the extra colour.

Backwashing :

Backwashing is the process in which the dyed material is washed first in soap solution, then in acid solution and then in oil. The material is then dried under heat.

Final Shade approval:

The shade of the dyed material is again checked and if found correct the material is sent to recombing department for further processing.

Yarn dyeing:

The yarn in the shape of cones is dyed, the various stages in yarn dyeing are as given below

Page 11: OCM

Shade checking:

The yarn is checked for the shade required with matching the shade and if the shade is rejected the material is reprocessed.

Hydroextractor:

The yarn is then processed in hydroextractor machines which extracts the extra water colour from the yarn.

R.F. Drying :

The yarn is dried in R.F. dryer machines which dries the yarn and make them ready for spinning or further processing.

Fabric / Piece Dyeing :

Dye House also dyes fabric which requires specific shades. These fabrics are woven as white fabric and dyed afterwards. This process is also called piece dyeing. The various stages in this process are :

Shade checking:

The shade is checked after dyeing the fabric and if found incorrect the material is dyed again.

If the shade matches with the required shade, the material is sent to hydroextractor machine.

Hydroextractor:

Hydroextractor machine extracts the extra colour & water from the dyed material. To Finishing : The dyed fabric is sent to Finishing Dept for drying and checking of any defects. If found defective the fabric is sent back to Dye House for reprocessing.

NEW SPINNING

Spinning

Spinning may be defined as " A set of operations the textile fabric must undergo to be converted into yarn."

PROCESS REQUIRED TO CONVERT WOOL FIBRE INTO YARN

The various stages in this process are listed below :> BLENDING> PRE-COMB GILLING> GILLING> POST-COMB GILLING> PREPARATORY OR DRAWING> SPINNING

These sections are briefly discussed here :

BLENDING:

A homogenous blend is necessary for best results. Thus, wool from different bales of the same lot is mixed together to make a big blend. The wool is spread over a certain area and an emulsion (made of 1 part of batching oil and 18 to 20 parts of water) is sprayed over each layer of wool.

PRE-COMB GILLING :The carded sliver contains some impurities which should be

removed before further processing. These impurities include :

The Procedure :Slivers are fed at the back of the Gill box through which the slivers

enter the back rollers and after processing by the Gill box passes on to the delivery can through front rollers. The front and the back rollers revolve at different speeds, later being slow. This difference in speeds of two rollers pull the sliver and thus the weight per unit length of the sliver is reduced as required. This process is called Drafting.

COMBING :

Page 13: OCM

The sliver at this stage may contain neps, vegetable matter and short or broken fibres. These faults are removed this stage.

The procedure :A number of slivers are fed to the machine. These slivers pass

through various rollers which feeds the sliver into the combing section. In the combing section, the sliver is passed through a comb, containing pins, which in turn combs the sliver. The combed sliver passes through the crimping unit to give crimp to the wool and at the end the sliver is collected in a can through a coiler unit.

The main functions of combing operation are given below :a) To remove the neps formed in the carding operationb) To remove the vegetable matter.c) To remove the short fibres of predetermined length as noil.

POST COMB GILLING :

In this stage the recombed top sliver is given two gilling. The purpose of two gilling is:

- To remove the wavy pattern of the combed sliver formed due to the overlapping of the successive combed fibres.

- To even out the irregularities in weight per unit length of the sliver.- To collect the sliver in the form of a ball. It is called wool top.

SPINNING

The Spinning Section can be further classified into thre sections:

> Spinning frame or Ring frame> Autoclave> Autoconing

Spinning Frame or Ring Frame :

The function of ring frame is to process the roving and produce the desired count of yarn within the spinning process.

THE PROCESS :The main stages in this section are listed below :

- DRAFTING- TWISTING- WINDING

Page 14: OCM

- LIFTING & BUILDING

The output of spinning process is YARN.

Page 15: OCM

POST SPINNING

The Post Spinning Section can be divided into following stages :

> Assembly Winding> Two-for-One Twisting> Autoclave

Assembly Winding :

Assembly winding is the process in which two single yarns are wound together on to a parallel cheese.

The Process :

Two cheeses or cones of single yarn are placed in supply pegs and yarn from both the cones or cheeses are wrapped round the cheese on the cheese holder. If one end breaks or runs out the winding stops. This motion prevents any single end being wound on to the cheese. When the end breaks these are joined by splicing.

Two-for-one Twister: The function of this stage is to

Twist the assembly wound yarn Wind the twisted yarn on to a cone or

cheese.

The process:

The T.F.O. twists the assembly wound yarn and winds the yarn on to cheese or cone. In each revolution of the spindle. T.F.O. inserts two turns in the yarn. This is how it is known as 'TWO FOR ONE' twister.

The yarn from supply package is passed through the spindle top. The formation of balloon is prevented by balloon limiter. In this process one full package is made out of one full assembly wound cheese and the end breakage is negligible and hence the knots are negligible.

Autoclave :

The yarn is steamed after twisting to set the twist and to avoid snarling. This also improves the strength of the yarn. After steaming the yarn is set for conditioning . At the end of this section each cone is checked completely for any defects and the approved cones are stored in cone store.

Page 16: OCM

WEAVING

Weaving interlaces warp and weft yarns in a certain definite pattern to form cloth, Weaving transforms the yarn into fabric on a loom which interlaces two sets of threads i.e.

WARP : Which runs down the length of cloth.

WEFT : Which lies at right angles to the warp-crossing the fabric from selvedge to selvedge.

The five basic functions which a loom has to perform to weave the cloth are listed below :-

Shedding;

The warp threads which runs down the length of the cloth are to be set to make way for the weft thread to pass in between them. The warp threads are separated vertically and the way for weft is made. This vertical separation of warp is known as shedding.

Picking :

This is the process of giving the shuttle (or rapier or projectile with weft) the propelled motion across the race plate through the separated warp is known as shedding.

Beating Up:

The weft yarn inserted in warp threads need to be pushed on the cloth side before the next weft yarn is inserted. This pushing of the weft yarn into the 'fell' of the cloth by means of Reed mounted on the oscillating sley is called beating up.

Taking Up :

The weaved fabric is wound on the cloth beam on the other side of the machine and this winding is known as taking up. The rate of taking up controls the number of picks of weft threads per inch.

Thus, the fabric is manufactured on the looms and sent to Greasy Perch for checking of defects.

Page 17: OCM

MENDING

This section is very important as this section corrects any kind of defects in the fabric. No machine is used for Mending. The fabric from Greasy Perch is checked on the perches and the defects are removed. The fabric is again checked on the perches by the Inspectors after Mending and the approved fabric is sent to Finishing.

The main imperfections are repaired by either Picking or Burling.

PICKING :

Picking is the process in which all kemps, straws, heir etc. are removed from the surface by picking.

BURLING:

This process consists of removing all the slubs etc. by following the below given procedure :

Opening the knot Pushing through to the back of the cloth any irregularities,

which appear on the face, so that all this is cleared as possible.

Page 18: OCM

FINISHING

The fabric before going to the Warehouse needs Finishing and Inspection and these two processes are very important for the fabric. The Finishing operation can be divided into WET and DRY Finishing. The various Finishing operations are given below :-

Scouring :

Scouring is the process of thoroughly cleaning the fabric and making it free of all greasy/oil particle for the subsequent operation of milling. The cloth is passed through scouring machine in an endless band which dips into a scouring liquor. A pair of nipping roller squeezes out the surplus suds and liquor from the cloth.

Milling or Fulling ;

This process transforms the cloth into a well-interlaced and tense felty mass by friction, heat and moisture. Milling machine comprises with receptacle for the cloth, heavy milling rollers to mill up the cloth in width and a funnel or box which can be weighed to mill up the cloth in length.

Drying or Stentering :

This machine embody the means of applying finish to woven fabrics without ill effects on the handle or colour variable. Speed driving allows the fabric to run through various part of the machine at requisite speed to give the desired results. Various arrangements of fans for circulating air over steam heated pipes are provided to show this warm air through the cloth, moist and finally exhausting to atmosphere at a suitable point in the machine. There are controls for speed and measuring instruments to record the length of the fabric run through and its width.

Steaming :

Blowing steaming through the fabric two or three minutes helps in relaxation of strains and then a permanent set. This process of steaming is done to improve the finishing of the fabric. The fabric is then allowed to cool before further reprocessing.

Crabbing :

This process has the same objects as of steaming, but hot water is used instead of steam. The cloth is unwound and run at full width through the trough containing hot water. Finally the cloth is passed to the hollow steaming roll where on it is wound.

Page 19: OCM

INSPECTION

The fabric from finishing is inspected in this section before delivering it to the Warehouse. The fabric is received by the Inspection Department and checked on perches to inspect the fabric on both the sides and putting flags on the defective portions. The Cloth Inspector puts two types of flags (yellow & white colour thread) on the selvedge indicating the defective portion of the fabric.

Yellow flag :

The yellow coloured flag indicates major defects like hole, loom repair, yarn bar, lever missing, float bunch and patch etc. The yellow flag indicates to cut the fabric at that portion.

White flag :

White flags indicates very minor defects like minor contamination, Mending, Marks, Minor Stains, small broken pick and ends etc.

The pieces which require remending, are tied with white tags and with relative details and sent to Mending Department. Not O.K. pieces which require re-processing are tied with yellow tags with relative details and sent to Finishing Section.

Cutting Instructions ;

The cutting instructions are received from the concerned Department.

Civil - from - SalesExport - from - PPC

In case no cutting instructions, the fabric is sent to Warehouse cutting it at yellow flags.

♦ The checker checks shade with the standard folder.♦ After cutting the fabric into 'thans' each and every 'than' is weighed.♦ Pieces which require assessment committee attention are taken out

from measuring and shown to the committee and treated according to the decision of the committee.

Process Damage :The fabric which got damaged in process and which is not

saleable in thans, suit lengths, coat lengths or pant lengths is shown to the committee and a record is kept of them. These are sent to the Warehouse with a damage stamp on them.

Page 20: OCM

WAREHOUSE

The material from Inspection Department is received in Warehouse and a record is kept. The badly finished or wrong product is sent back to Finishing for reprocessing with a note after recording the same in records.

The vouchers received are checked for any mistake for :♦ Design♦ Gradation♦ Metres etc.by piece ticket.

Then the material is kept on racks according to the quality (after sorting for quality)

New designs are placed at new placesAll wool fabric and wool blended fabric are kept separately.

The Procedure :

The Warehouse Department receives advice from Sales Department about despatch schedule and accordingly the material is collected from the racks and shelves. According to the allocation slip of the 'Sales', the Challan and proforma invoice are printed in three copies each.

After printing the challan, the material is checked with the challan for :

♦ Quality♦ Shade♦ Length and weight

The verified proforma invoice and challan are sent to despatch section, which attaches the lorry receipt with it and sends the documents to invoicing section.

The Invoicing Section checks the whole set of documents and completes some more formalities and sends the documents to the customer or agent under advice from sales. The material is packed in packing section with waterproof material and further tied strips. The material is then delivered through the transport company advised by the Sales Department. The various modes of transport in operation are :

♦ Road transport♦ Railways♦ Messenger delivery♦ Post parcel♦ Through courier

Page 21: OCM

♦ Air cargoQ.C. LABORATORY

The Quality Control laboratory acts as the main controller of quality of the product. The raw material i.e. wool and the finished product i.e. fabric both are tested for quality in Q.C.Lab. Stage wise quality of fabric are also controlled by this department.

Some of the important tests which are carried out in Q.C.LAB are briefed below :

BLEND (Composition):

Chemical tests are used to find out the blend of the fabric. One ingredient is dissolved in the chemicals and the residual is dried and wighed, which in turn gives the percentage of ingredients. Thus, the blend or composition is found by chemical testing.

CROCK MEDIAN TEST (Bubbling test ):

This test checks the staining effect of the product. The fabric to be tested is sandwiched in between light shaded fabric in the machine and the staining effect is tested.

BREAKING STRENGTH:

The breaking strength of the fabric is tested in this test. The sample of the fabric to be tested is fitted into the machine and the fabric is pulled from both the ends and the breaking strength is noted by recording the point where the fabric breaks. A minimum limits is fixed as per standards and the results are matched to the fixed standard and report is prepared.

SEAM SLIPPAGE :

In this test, the fabric is stitched at one end and the breaking strength of the fabric is noted around that end. The machine used in the breaking strength test is used in this test and the procedure is also almost same.

COLOUR FASTNESS TO WASHING :

The colour fastness of the fabric is noted in this test and the sample is tested for the extent it loses colour in the test.

SHRINKAGE:

The shrinkage property is tested in this test. The fabric of different blends are tested by different methods e.g. All wool is tested for shrinkage by

Page 22: OCM

soaking it in cold water only.
