diameter of upto five, which are used for wear.
Machine for outerwear and under wear may vary from 12 inch to 60 inch in
diameter according to manufactures requirement. This m/c can be used either as fabric or
for making garments completely with fancy stitch. Latch needles are commonly
employed in all modern circular m/c because of their simple action and also their ability
to process more types of yarns.
Plain circular m/c uses only one sets of needles, circular rib m/c uses two sets
of needles i, e, Cylinder needle and Dial needle, the interlock circular knitting m/c also
uses two sets of needles by needles are long and short respectively for both dial and
cylinder, that is why multiple design and thick fabric can be produce with that m/c. That
m/c is also called double Jersey m/c.
 M/c. Gauge – needle/inch (varies according to diameter)
 Needle Type – Latch
 Needle bed type – Single cylinder, Double cylinder, Cylinder &
Dial, long or short needles for cylinder and dial.

5.2 DESCRIPTION OF PRODUCTION PROCESS:
In every mill, there maintains a sequences in production processing. It is also
followed in this mill where I was in industrial attachment. The process sequences are in
list below:
1) Firstly, knitting manager gets a production sheet from merchandisers as
accordance as consumer requirements. Then he informs or orders senior production
officer about it.
2) Senior production officer informs technical in charge and knows about m/c
in which the production will be running.
3) Technical in charge calls for leader of mechanical fitter troops, they two
take decision about m/c for production considering m/c condition, production capacity,
maintenance complexity etc.
4) Production officer with experienced mechanical fitter adjusts required stitch
length and grey GSM (gram per square meter) for required final GSM.
5) Supervisor check daily production regularity and make operators conscious
about finishing in due time.
6) Operators operate machine in highly attention as if there were no faults in
the fabrics. If he thinks or sure about any fabric fault, then he call for mechanical fitter in
duty. Mechanical fitter then fixes it if he can or he informs technical in-charge. He then
comes in spot.
7) After required production and final inspection in 4-point system, they are
sent in dyeing section.

CHAPTER – VI
(QUALITY ASSURANCE SYSTEM)

38
6.1 CONTROL OF FABRIC QUALITY:
Control of the quality of the cloth being knitted is the knitting mechanic’s major
responsibility. Fabric set-ups and m/c maintenance, although necessary, must be put into
their 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 an
immediate cure. To do this, he must have a thorough knowledge of what causes a defect
in 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/c
2) Scissors
3) Weight balance & Micro balance
4) GSM cutter
5) Seal.
6) Marker
6.3 FABRIC DEFECTS:
Defects in circular knitted cloth fall into the following major groups: vertical
lines, 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. This
uneven movement of the needles will cause uneven stitches which is turn can cause
vertical lines.
If a wall is too big for the needle, the needle will have a sideward motion, which
will cause formation of a wide wale in the fabric. When the trick walls are not evenly
spaced, the needles will knit a certain points wide and narrow stitches in the fabric. These
will also cause unsightly lines.
Dirt may often get into the tricks pushing the needles outwards (cylinder) or
upward (dial) causing irregular vertical stitches. Bent and worn needles will cause the
fabric to have wider Wales in certain places.
Needles with chipped latches, butts, hooks, cheeks, a protruding rivet or broken
spoons will cause fuzzy and irregular vertical lines. Needles with bent latches will cause
vertical tears or ladders in the fabric. Too much lubrication or the use of improper needle
oil often causes oil or dirt strakes.
Dark black vertical lines may be caused by dirty tricks, which cause the needles to
run high and rub against the cams. Not enough lubrication may also be the cause of black
vertical lines.

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 and
5. Defective take down mechanism
With the use of positive feeding devices, the stitch cam adjustment is
Very accurate. The most important thing to remember when adjusting stitch cams is to
keep the ratio of the dial stitch to the cylinder stitch the same at all the dial and cylinder
feeds.
It must be remember that a positive feed system (tape) will feed the same amount
of yarn to all feeds regardless of stitch adjustment. This stitch adjustment controls the
tension only.
In the case of pique fabric or any similar kind, the odd feeds must be done at the
same tension, but the even form the odd feeds so long as they are all the same. We know
now 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 be
clean of any instruction which will caused irregular tension.
A defective takes down mechanism which pulls tight and then soft will cause are
as on the fabric to be loose and tight. The take down mechanism must pull evenly at all
times to maintain a fabric with even courses.
If dial is not in the proper relationship to the cylinder, fabric of uneven stitch
length will produced. The dial and cylinder relationship should be inspective at least once
a year to maintain proper running conditions.
Uneven thickness of the yarn is one of major causes of barre. The mechanic is
really helpless in the situation. The only thing he can do is to learn to recognize this
condition and notify the throwster immediately.
Badly wound yarn also will cause uneven tension. In most cases a positive feed
system will eliminate this defect, but if one used the mechanic should have the yarn
rewound. In the case of dyed yarn shaded the mechanic is helpless in such a situation, he
must 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,

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 at
a low tensions and then suddenly jerks and runs at a high tension. This high tension wills
usually 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 the
yarn is not fed directly into the hook of the needle, there is a good chance that the needle
will 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 the
carrier, dial needle latch closing under yarn carrier and dial needle latch closing near the
hole 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 to
needle. 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 industries
and 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 and
quantity, both depends on the maintenance with regularity. Jinnnat Apparels Ltd. lead
maintenance with a troop of skilled mechanical fitters.
Two types of maintenance are carried out. They are -
a. Break down maintenance
b. 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 fault
b. 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 process
b. Sound running of machine
c. Longer useful life of machine
d. Better quality of product
e. Lower rejection of machine parts
f. Lower load on operator
7.2 FUNCTION OF MAINTENANCE:
a. Inspection:
Faulty parts are identified &their present condition are checked. And also
availability of stand by equipments are also checked.
b. Lubrication:
Before starting maintenance all moving & frictional parts are lubricated so
to 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 manual
iii. History card iv. Inspection card
v. 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.

45
g. Storage & record
The 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 handing
over from previous shift operator, he takes a routine maintenance on the machine. He
cleans 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 neat
and clean as if there is no dirt with yarn in the fabric.
2) Schedule/Routine Maintenance: Every machine has a schedule of
maintenance of 10 or 15 days. According to date, schedule maintenance is taken on the
machines. Operators are informed about the time of maintenance. After pre-estimated
production, they hand over the machine to the fitters. Thus, fitters assure all machines are
OK. for any time.
3) Break down maintenance: When product quality hampered and to complete
production in due time break down maintenance is taken. There are many faults seen in
the fabric during production due to needle, sinker, take down roller etc. Then operators
inform the mechanical fitters and they fix it.
4) Restorative maintenance: Restorative maintenance is taken for design
change or new design development. According to advice or order of production officer, a
machine is fixed for new design and mechanical fitters rearrange cam and needle system.
Planned and preventive maintenance are not taken on the machineries in this
mill.
7.4 MANPOWER SET UP FOR MAINTENANCE:
There are two shifts in this mill. Two groups of mechanical fitters for four
persons work for two shifts. Each group having a leader, a needle man and two assistant
fitters. Fitters work under the technical in charge for knitting section only. They all are
very efficient and hard working. They can fix any type of mechanical problem of
machines. No necessity happens to hire others from outside to fix machine maintenance.
There are electro-mechanical groups to work for electrical problem of machineries. They
work 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:

46
1) For there is any mechanical fault of machine which is responsible for
production hamper, operator informs mechanical fitters in duty. Mechanical fitters come
and 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 founding
mechanical problem, mechanical and electrical department are informed, they come and
fix the problem. They commence at work after informing of knitting manager. There are
two mechanical engineers in the department.
4) For restorative maintenance, senior production officer orders mechanical
fitters to fit required machine for cam and needle arrangement and other necessary
requirements in case of new design development.
