3.10 REMARK: Ventilation system is very poor . The room Height of knitting section is

inadequate . There is no exhaust fan to clean and maintain the temperature ofthis section. The temperature of this section is more than the natural room temperature

because it absorb heat from dyeing and finishing section. There is only one toilet which is not sufficient. Grey fabric inspection section should be air conditioned. At least six circular m/c can be easily setup on the basis of present floor

condition. Cone storage facilities are not bad. The floor plaster of some place of this section is damaged , so it is necessary to

repair it as soon as possible. Creel of camber m/c is not suitable because it has required more floor space and

also difficult to change package.

5.11 METHODS OF INCREASING PRODUCTION:

By the following methods the production can be increased –

1. By increasing m/c speed:Higher the m/c speed faster the movement of needle and ultimately production

will be increased.

2. By increasing the number of feeder:If the number of feeder is increased in the circumference of cylinder, then the

number of courses will be increased in one revolution at a time.

3. By using machine of higher gauge:The more the machine gauge, the more the production is. So by using machine of

higher gauge production can be increased.

4. By imposing automation in the m/c:a) Quick starting & stopping for efficient driving system.b) Automatic m/c lubrication system for smoother operation.c) Photo electric fabric fault detector.

5. By imposing other developments:a) Using creel-feeding system.b) Applying yarn supply through plastic tube that eliminates the

possibilities of yarn damage.c) Using yarn feed control device.d) Using auto lint removal.

5.12 CAUSES OF LOOP LENGTH VARIATION:1. Fluctuation in yarn variable:

a) Due to count variation.b) Due to twist variation.c) Due to insufficient M.C. or M.R.d) Due to package hardness.e) If frictional property of yarn is not maintained.

2. Fluctuation in m/c variable:a) If temperature of the m/c is not standard.b) If m/c gauge is not accurate.c) If m/c cam setting is not properly maintained.d) If needle timing and knock over is not accurate.e) If take down tension is wrong.f) If sinker timing is not correct.g) Improper yarn tension.

3. Robbing back:Due to 15% of yarn robbed back from old loop to newly formed loop.

CHAPTER – VI(QUALITY ASSURANCE SYSTEM)

Page 38: Industrial attachment of jinnat apparels ltd

38

6.1 CONTROL OF FABRIC QUALITY:

Control of the quality of the cloth being knitted is the knitting mechanic’s majorresponsibility. Fabric set-ups and m/c maintenance, although necessary, must be put intotheir proper order of importers. To set-up a fabric and run it on a well-maintained m/c,when its quality is questionable, is senseless.

The mechanic must be able to diagnose a problem on a m/c and render animmediate cure. To do this, he must have a thorough knowledge of what causes a defectin fabric. When the cause is known, correction will soon follow.

6.2 LIST OF EQUIPMENTS:

The list of equipments to assure quality:-1) Inspection m/c2) Scissors3) Weight balance & Micro balance4) GSM cutter5) Seal.6) Marker

6.3 FABRIC DEFECTS:

Defects in circular knitted cloth fall into the following major groups: verticallines, barre, holes and snags, tuck or double stitches, these will be discussed seriatim.

a. Vertical lines:This defects can be caused by defective needles or defective trick walls. If the

trick walls are worn or not evenly spaced, the needles will knit at different speed. Thisuneven movement of the needles will cause uneven stitches which is turn can causevertical lines.

If a wall is too big for the needle, the needle will have a sideward motion, whichwill cause formation of a wide wale in the fabric. When the trick walls are not evenlyspaced, the needles will knit a certain points wide and narrow stitches in the fabric. Thesewill also cause unsightly lines.

Dirt may often get into the tricks pushing the needles outwards (cylinder) orupward (dial) causing irregular vertical stitches. Bent and worn needles will cause thefabric to have wider Wales in certain places.

Needles with chipped latches, butts, hooks, cheeks, a protruding rivet or brokenspoons will cause fuzzy and irregular vertical lines. Needles with bent latches will causevertical tears or ladders in the fabric. Too much lubrication or the use of improper needleoil often causes oil or dirt strakes.

Dark black vertical lines may be caused by dirty tricks, which cause the needles torun high and rub against the cams. Not enough lubrication may also be the cause of blackvertical lines.

Page 39: Industrial attachment of jinnat apparels ltd

39

b. Barre or uneven courses:The following may cause these faults :

1. Improper cam adjustment,2. Uneven yarn tension,3. Different yarn thickness or shaded yarn dyes,4. Dial not in even relationship to cylinder and5. Defective take down mechanism

With the use of positive feeding devices, the stitch cam adjustment isVery accurate. The most important thing to remember when adjusting stitch cams is tokeep the ratio of the dial stitch to the cylinder stitch the same at all the dial and cylinderfeeds.

It must be remember that a positive feed system (tape) will feed the same amountof yarn to all feeds regardless of stitch adjustment. This stitch adjustment controls thetension only.

In the case of pique fabric or any similar kind, the odd feeds must be done at thesame tension, but the even form the odd feeds so long as they are all the same. We knownow that the yarn tension will control the length of stitch.

It is very important that any surfaces that the yarn runs over or through mist beclean of any instruction which will caused irregular tension.

A defective takes down mechanism which pulls tight and then soft will cause areas on the fabric to be loose and tight. The take down mechanism must pull evenly at alltimes to maintain a fabric with even courses.

If dial is not in the proper relationship to the cylinder, fabric of uneven stitchlength will produced. The dial and cylinder relationship should be inspective at least oncea year to maintain proper running conditions.

Uneven thickness of the yarn is one of major causes of barre. The mechanic isreally helpless in the situation. The only thing he can do is to learn to recognize thiscondition and notify the throwster immediately.

Badly wound yarn also will cause uneven tension. In most cases a positive feedsystem will eliminate this defect, but if one used the mechanic should have the yarnrewound. In the case of dyed yarn shaded the mechanic is helpless in such a situation, hemust notify the throwster immediately.

c. Holes and Snags:Holes in most cases are caused by excessive tension of the yarn. If stitch cams are

adjusted too deep and there is excessive tension in the yarn, it wills beak, causing a hole.If the dial height is too high these will also cause a tremendous strain on the yarn.Other factors that produce excessive tension on the stitch are as follows:

1. Too tight a take down pup,

Page 40: Industrial attachment of jinnat apparels ltd

40

2. The positive feed system operating improperly,3. Badly wound yarn,4. Yarn with thin or weak spots.5. Dirty or clogged surface in which the yarn passes through or on,6. Yarn warp around.

Snags in most cases are usually caused by badly wound yarn which ata low tensions and then suddenly jerks and runs at a high tension. This high tension willsusually a line of holes from one to nine inches.

d. Drop Stitches:This defect occurs when the needle tails to take new yarn of when the needle fails

to take new yarn or when the needle losses its loop.

One of the major causes of this problem is an improperly set yarn carrier. If theyarn is not fed directly into the hook of the needle, there is a good chance that the needlewill not take the new yarn.

If the stitch cam is set too far back there will be too much yarn is the needle loop.Because of this loop will be so loose that it can fall causing a drop stitch.

Other possible causes of droop stitches are: the take down mechanism is too loose,not enough tension on yarn, dial height too high, needles, yarn in wrong hole of thecarrier, dial needle latch closing under yarn carrier and dial needle latch closing near thehole of the carrier.

e. Tuck Stitches or Double Stitches:This defect occurs when the needle does not cast off its old loop. In most cases

this defect can be traced to an improperly set stitch cam.

If the needle is not drown far enough back the old loop will remain on the needle.On the other hand, if the stitch cam is set too far back, too much yarn will be going toneedle. In this case this needle will be unable to knock over such a large loop.

Other possible causes of Tuck Stitches are as follows:

1. Take down mechanism set too loose,2. Needles move too freely in their slots,3. Dial height set too low,4. Defective needles,5. Needle trick walls clogged with dirt etc.

7.1 MAINTENANCE OF MACHINERY:

Maintenance of machineries is very important for any type of industriesand it is a must for a knit composite mill. All machines and machines parts of knitting,dyeing and garments are maintained with extreme care. Because production quality andquantity, both depends on the maintenance with regularity. Jinnnat Apparels Ltd. leadmaintenance with a troop of skilled mechanical fitters.

Two types of maintenance are carried out. They are -a. Break down maintenanceb. Schedule maintenance

a. BREAK DOWN MAINTENANCE:This type of maintenance is carried out only when machine remains

stop due to-a. Break down for mechanical faultb. Break down for design changing

b. SCHEDULE MAINTENANCE:Every machine has a definite maintenance schedule which is

performed after a certain periodic interval to ensure –a. Smooth production processb. Sound running of machinec. Longer useful life of machined. Better quality of producte. Lower rejection of machine partsf. Lower load on operator

7.2 FUNCTION OF MAINTENANCE:a. Inspection:

Faulty parts are identified &their present condition are checked. And alsoavailability of stand by equipments are also checked.b. Lubrication:

Before starting maintenance all moving & frictional parts are lubricated soto facilitate &draw off the parts.c. Record & analysis:

Previous records & history of the maintenance are checked and analyzed.Before maintenance the following records should be checked:

i. Operating manual of the m/c ii. Maintenance manualiii. History card iv. Inspection cardv. Log book

d. Planning & scheduling:Taking of proper plan & making of specific schedule how the maintenance

should be performed properly.e. Operation:

The maintenance operation is performed as stated below.f. Replacement of faulty parts

The faulty parts which are identified replaced by new parts.

Page 45: Industrial attachment of jinnat apparels ltd

45

g. Storage & recordThe faulty parts which are rejected stored properly & keep top to bottom

record of this operation.

7.3 ROUTINE:1) Daily Maintenance: Every machine is taken maintenance daily by the

operators during production. When a production is started by the operator after handingover from previous shift operator, he takes a routine maintenance on the machine. Hecleans the machine, assures yarn is fed to all needles, cleans the eye pot of feeder,memminger, signal lamp sensor etc. Before a while of a roll cut from batch or cloth roller,operator cleans needles, cylinder base plate etc. All around of the machine are kept neatand clean as if there is no dirt with yarn in the fabric.

2) Schedule/Routine Maintenance: Every machine has a schedule ofmaintenance of 10 or 15 days. According to date, schedule maintenance is taken on themachines. Operators are informed about the time of maintenance. After pre-estimatedproduction, they hand over the machine to the fitters. Thus, fitters assure all machines areOK. for any time.

3) Break down maintenance: When product quality hampered and to completeproduction in due time break down maintenance is taken. There are many faults seen inthe fabric during production due to needle, sinker, take down roller etc. Then operatorsinform the mechanical fitters and they fix it.

4) Restorative maintenance: Restorative maintenance is taken for designchange or new design development. According to advice or order of production officer, amachine is fixed for new design and mechanical fitters rearrange cam and needle system.

Planned and preventive maintenance are not taken on the machineries in thismill.

7.4 MANPOWER SET UP FOR MAINTENANCE:

There are two shifts in this mill. Two groups of mechanical fitters for fourpersons work for two shifts. Each group having a leader, a needle man and two assistantfitters. Fitters work under the technical in charge for knitting section only. They all arevery efficient and hard working. They can fix any type of mechanical problem ofmachines. No necessity happens to hire others from outside to fix machine maintenance.There are electro-mechanical groups to work for electrical problem of machineries. Theywork for overall factory.

Manpower set for different m/c maintenance:# For single jersey m/c: 3-4 person/ hrs.# for double jersey m/c : 7-8 person/ hrs

7.5 MAINTENANCE PROCEDURE:

Page 46: Industrial attachment of jinnat apparels ltd

46

1) For there is any mechanical fault of machine which is responsible forproduction hamper, operator informs mechanical fitters in duty. Mechanical fitters comeand observe the problem firstly, and then they begin to fix it.

2) If mechanical fitters be unable to fix it, then they inform technical in-charge,he then comes in spot and fix it.

3) For there is any electrical problem of machine or serious foundingmechanical problem, mechanical and electrical department are informed, they come andfix the problem. They commence at work after informing of knitting manager. There aretwo mechanical engineers in the department.

4) For restorative maintenance, senior production officer orders mechanicalfitters to fit required machine for cam and needle arrangement and other necessaryrequirements in case of new design development.
