3. INTRODUCTION
Industrial attachment is an essential part of 4-years B.Sc. in Textile Technology
course of southeast university . I had the opportunity to perform the industrial
attachment with Jinnat Apparels Ltd. During 45 days long attachment, I studied the
man, machines, material aspects of the circular knitting section, quality control section,
planning section, grey fabric inspection section and finished fabric inspection section
of the mill.I also had a short visit in the garments section of the factory. According to
my studies there I have prepared the following report and would like to present.

KNITTING SECTION
# Process definition:
Knitting is the interlocking of one or more yarns through a series of loops. The
length wise columns of stitches corresponding to the warp in woven cloth are called
Wales, the width wise rows of stitches corresponding to the weft are known as courses,
weft knits are those fabrics in which the courses are composed of a single strand of
yarn. While warp knits are those in which the Wales are composed of single strands of
yarns. Gauge corresponds to the yarn count in a woven fabric and is defined as the
number of needles or yarns, in ½ inches of cloth. The higher the gauges the more
compact finer the cloth.
# Process requirements:
In Jinnat Apparels Ltd. two types of machines are used for producing knitted
fabric. These are –
1. Circular Single Jersey m/c.
2. Circular Double Jersey m/c.

13. CIRCULAR KNITTING MACHINE
Circular knitting m/cs. are widely used through out the knitting industry to
produce fabric. This m/c can be built in almost any reasonable diameter and the
small 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.
 Two principle operation exist:
1. English system – Where the cams and yarns strands revolve by needle
and fabric take down is stationary.
2 American system – Where the needles and fabric take down revolves
by cams and yarn strands are stationary.

possibilities of yarn damage.
c) Using yarn feed control device.
d) Using auto lint removal.
26
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.

25. 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.
27
CONTROL OF FABRIC QUALITY
Control of the quality of the cloth being knitted is the knitter 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.
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.
 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

26. 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.
28
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.
 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.

27. 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.
29
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.
 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,
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.

28. 30
 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.
 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,

CONCLUSION
College of Textile Technology has given me the field to perform the industrial
attachment with Jinnat Apparels Ltd. This attachment seems to me as a bridge to

34. minimize the gap between theoretical and practical knowledge. Undoubtedly, this
attachment paved us the way to learn more about Textile Technology, industrial
practices, and industrial management and production process. Besides this attachment
gave us the first opportunity to work in an Industry and acquainted us with the internal
sight and sound of Textile Industries. I believe with all these, the experience of the
industrial attachment will help our future life as a Textile Technologist.
