CHAPTER-06
KNITTING SECTION
INDUSTRIAL INTERNSHIP REPORT SOUTHEAST UNIVERSITY
25 URMI Group
Knitting:
Knitting is a process of manufacturing a fabric by inters looping of
yarns. Knitting is the second most important method of fabric formation. It can be defined as
a needle technique of fabric formation, in which, with the help of knitting needles, loops are
formed to make a fabric or garment. Fabric can be formed by hand or machine knitting, but
the basic principle remains exactly the same i.e. pulling a new loop through the old loop.
In other words, Knitting is a method by which thread or yarn may be turned into
cloth or other fine crafts. It is a fabrication process i.e. intermeshing series of loops of one or
more yarns or from a set of yarns. Knitted fabric consists of consecutive rows of loops, called
stitches. As each row progresses, a new loop is pulled through an existing loop. The active
stitches are held on a needle until another loop can be passed through them. This process
eventually results in a final product, a garment. Knitting may be done by hand or by machine
.Different yarns and knitting needles may be used to achieve different end products by giving
the final piece a different color, texture, weight, and/or integrity. Using needles of varying
sharpness and thickness as well as different varieties of yarn can also change the effect. A
INDUSTRIAL INTERNSHIP REPORT SOUTHEAST UNIVERSITY

knitted fabric is the third major class of fabric, after woven and nonwoven fabrics.
In knitting, the inter-lopping is carried out by needles (may be Latch or beard or
compound needle etc), the needles are equipped on a cylinder and Needle butt moves
between the grooves of cams to accomplish knitting cycle and producing the fabric. The
shape of the needle cam grooves depends on the required knitting pattern.
All over the world, the majority of knit fabrics are manufactured on circular knitting
machines. The high performance level of these machines, the different materials and the
range of yarn counts that they are able to process, the wide variety of designs and stitches are
some of the reasons which have granted circular machines the market leadership in the
knitting sector.

Terms of Knitting:
Course:
Horizontal row of loops produced by adjacent needles in knitting cycle is called the course of
the fabric. A course is a predominantly horizontal raw of needle loops produced by adjacent
needles during the same knitting cycle called course. (Loop length * No of loop).
Wales:
Vertical column of loops produced by same needle in knitting cycle is called the Wales of the
fabric.
INDUSTRIAL INTERNSHIP REPORT SOUTHEAST UNIVERSITY
39 URMI Group
A wale is a predominantly vertical column of intermeshed needle loops generally produced
by the same needle knitting cycles. i.e. The number of vertical columns of loop of knitted
fabrics is called wale.
Face loop:
If the legs of new loop is passes over the old loop is called face loop.
Back loop:
If the legs of new loop is passes under the old loop is called face loop.
Stitch density:
The term stitch density is frequently used in knitting instead of a linear measurement of
courses or Wales; it is the total number of needles loops in a square area measurement such
as a square inch or three square centimeters.
It is expressed as,
Course per inch × Wales per inch.
Stitch length:
Length of one loop in the course direction express in mm.
Number of needle:
Machine diameter × Machine gauge × 3.1416.
GSM:
The weight of one square meter of fabric express in gram is known as GSM.
Needle gauge:
The needle gauge of a knitting machine is a measure expressed the no. of needle per unit of
the needle bed or needle bar. As for example:
1. In case of circular weft knitting machine & Tricot warp knitting machine. [Gauge,
N= Number of needle per inch.]
2. In case of Raschel warp knitting machine. [Gauge, N= Number of needle per two
inch.]

Needle:
There are three types of needle-
1. Bearded needle
2. Compound needle
3. Latch needle-
One butt needle.
Two butt needle.
Three butt needle.
Four butt needle.
The most widely used needle is latch needle.
Fig: Main parts of latch needle.
Cam:
Cam is called the specific path of the needles to produce a specific type of fabric.
INDUSTRIAL INTERNSHIP REPORT SOUTHEAST UNIVERSITY
41 URMI Group
There are three types of cam used in circular knitting machine:
1. Knit Cam.
2. Tuck Cam.
3. Miss Cam.
Knit Cam:
It moves the needle upward enough to clear the old loop and receive the new yarn.
Tuck Cam:
It moves the needle upward not enough to clear. The old loop but receive the new yarn.
Miss cam:
It does not move the needle upward. The needles neither clear the old loop nor receive the
new yarn.
Sinker:
It is a thin metal plate with an individual or collective operation approximately at right angles
at the hook side between adjacent needles.
INDUSTRIAL INTERNSHIP REPORT SOUTHEAST UNIVERSITY
42 URMI Group
Function of sinker:
In circular knitting m/c sinker helps to form the loop by holding down the yarn
Loop forming sequence of latch needle:
Latch Opening:
The needle goes upward and the sinker comes in action to hold down the loop. Then the old
loop press down the latch and it gets open.
Yarn Receiving:
INDUSTRIAL INTERNSHIP REPORT SOUTHEAST UNIVERSITY
43 URMI Group
The needle iscontinuous moving upward enough to receive the new yarn. The old loop
remains on the open latch that is called tucking on the latch position.
Clearing:
The needle goes to its ultimate height to clear the old loop and the new yarn still within the
reach of the needle.
Landing:
According to the path of cam, the needle starts moving downward. Being pushed by the old
loop the latch gets closed and the new yarn is entrapped within the closed hook.
Knock off:
The needle continues moving downward. When it reaches at the down position, the old loop
slides off from the back of the latch over the tip of the needle.This old loop then taken by the
take up roller hangs from the new loop.

Considerable points to produce knitted fabrics:
When a buyer orders for fabric then they mention some points related to production and
quality. Before production of knitted fabric, these factors are needed to consider. Those are as
follows-
Type of Fabric or design of Fabric.
Finished G.S.M.
Yarn count
Types of yarn (combed or carded)
Diameter of the fabric.
Stitch length
Color depth
Relationship between knitting parameter:
1. Stitch length increase with decrease of GSM.
2. If stitch length increase then fabric width increase and Wales per inch decrease.
3. If machine gauge increase then fabric width decrease.
4. If yarn count increase (courser) then fabric width increase.
5. If shrinkage increases then fabric width decrease but GSM and Wales per inch increase.
6. For finer gauge, finer count yarn should use.
7. Gray GSM should be less than finish GSM
Production Parameter:
Machine Diameter;
Machine rpm (revolution per minute);
No. of feeds or feeders in use;
INDUSTRIAL INTERNSHIP REPORT SOUTHEAST UNIVERSITY
45 URMI Group
Machine Gauge;
Count of yarn.
Responsibilities of a Production Officer :
Monitor and control shift wise production, plant utilization, waste generation etc.
implement correct work methods and maintain all records related to production.
Responsible for systematic planning and execution of production programs.
Adequate control over process in order to achieve quality of product & better waste
management.
Monitor shift wise production, utilization etc. and take corrective action for any
shortfall.
Maintain all the procedure of his department and shall incorporate amendments as and
when required in procedure.
Responsibilities for monitoring the performance of manpower under him and
identification of training needs.
Methods of increasing production:
By the following methods the production of knitted fabric can be increased –
By increasing m/c speed:
Higher the m/c speed faster the movement of needle and ultimately production
will be increased but it has to make sure that excess tension is not imposed on
yarn because of this high speed.
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.
By using machine of higher gauge:
INDUSTRIAL INTERNSHIP REPORT SOUTHEAST UNIVERSITY
46 URMI Group
The more the machine gauge, the more the production is. So by using machine
of higher gauge production can be increased.
By imposing other developments:
Using creel-feeding system
Applying yarn supply through plastic tube that eliminates the possibilities
of yarn damage
Using yarn feed control device
Using auto lint removal.
Factors that should be change in case of fabric design on quality change:
a) Cam setting
b) Set of needle
c) Size of loop shape
If shrinkage increases then fabric width decrease but GSM and Wales per
inch increase.
For finer gauge, finer count yarn should use.
Effect of stitch length on color depth:
If the depth of color of the fabric is high loop length should be higher because in case of
fabric with higher loop length is less compact. In dark shade dye take up% is high so GSM is
adjusted then. Similarly in case of light shade loop length should be relatively smaller
Some points are needed to maintain for high quality fabric:
INDUSTRIAL INTERNSHIP REPORT SOUTHEAST UNIVERSITY
47 URMI Group
Brought good quality yarn
Machines are oiled and greased accordingly
G.S.M, Stitch length, Tensions are controlled accurately
Machines are cleaned every shift and servicing is done after a month
Grey Fabrics are checked by 4 point grading system
Changing of GSM:
Major control by VDQ pulley
Minor control by stitch length adjustment
Altering the position of the tension pulley changes the G.S.M. of
the fabric. If pulley moves towards the positive direction then the
G.S.M. is decrease. And in the reverse direction G.S.M will
increase
Tension:
Tension should be control for different yarns, because for tension variation yarns may be
broke. Tension measured by Tension Meter.
Yarn Tension (CN)
Cotton (S/J) 4-5
Polyester (Single Jersey) 3.5-4
Double Jersey 2-2.5

= 61.52 ton/year
Machine No-14:
(Double Jersey Interlock)
= 9.14 kg/hr
= 73.13 kg/shift

Fabric Consumption:
Fabric Type = D-Fleece
Fabric GSM = 340
S/L of 30 Ne Dyed cotton yarn = 4.70
INDUSTRIAL INTERNSHIP REPORT SOUTHEAST UNIVERSITY
53 URMI Group
S/L of 30 Ne Grey cotton yarn = 3.40
S/L of 10 Ne Dyed cotton yarn = 1.65
We know,
Composition = S/L ÷ Ne
Now, 4.7 ÷ 30 =0.15667
And, 3.4 ÷ 30 = 0.1133
And, 1.65 ÷ 10 = 0.165
Total = 0.434
Composition of 30 Ne Dyed yarn = (0.15667×100)÷0.434
= 36
Composition of 30 Ne Grey yarn = (0.1133×100)÷0.434
= 26
Composition of 10 Ne Dyed yarn =(0.165×100)÷0.434
= 38
So the composition are,
30 Ne Dyed cotton yarn : 30 Ne Grey cotton yarn : 10 Ne Dyed cotton yarn = 36:26:38

Faults & Remedies of knitting fabric:
Hole Mark:
Causes:
Holes are the results of yarn breakage or yarn cracks.
During loop formation the yarn breaks in the rejoin of the needle hook.
If the yarn count is not correct on regarding structure, gauge, course and
density.
Badly knot or splicing.
Yarn feeder badly set.
Remedies:
1.Yarn strength must be sufficient to withstand the stretch as well as uniform.
2.Use proper count of yarn.
3.Correctly set of yarn feeder.
4.Knot should be given properly.
Needle Mark:
Causes:
When a needle breaks down then needle mark comes along the fabrics.
INDUSTRIAL INTERNSHIP REPORT SOUTHEAST UNIVERSITY
62 URMI Group
If a needle or needle hook is slightly bends then needle mark comes on the
fabrics.
Remedies:
Needle should be straight as well as from broken latch.
Sinker Mark:
Causes:
When sinker corrode due to abrasion then some times can not hold a new loop
as a result sinker mark comes.
If sinker head bend then sinker mark comes.
Remedies:
Sinker should be changed.
Star Mark:
Causes:
Yarn tension variation during production.
Buckling of the needle latch.
Low G.S.M fabric production.
Remedies:
Maintain same Yarn tension during production.
Use good conditioned needles.
Drop Stitches:
Causes:
Defective needle.
INDUSTRIAL INTERNSHIP REPORT SOUTHEAST UNIVERSITY
63 URMI Group
If yarn is not properly fed during loop formation i.e. not properly laid on to the
needle hook.
Take-down mechanism too loose.
Insufficient yarn tension.
Badly set yarn feeder.
Remedies:
Needle should be straight & well.
Proper feeding of yarn during loop formation.
Correct take up of the fabric & correct fabric tension.
Yarn tension should be properly.
Oil Stain:
Causes:
When oil lick through the needle trick then it pass on the fabrics and make a
line.
Remedies:
Ensure that oil does not pass on the fabrics.
Well maintenance as well as proper oiling.
Rust stain:
Causes:
If any rust on the machine parts.
Remedies:
If any rust on the machine parts then clean it.
Proper maintenance as well as proper oiling.
Pin hole:

Grease stain:
Causes:
Improper greasing
Excess greasing
Remedies:
Proper greasing as well as proper maintenance
Cloth fall- out:
Causes:
Cloth fall- out can occur after a drop stitch especially when an empty needle with an
empty needle with closed latch runs into the yarn feeder and remove the yarn out of the
hook of the following needles.
Remedies:
Make sure all the latches of needle are closed with feeding yarn after a
drop stitch.
Barrieness:
A fault in weft knitted fabric appearing as light or dark course wise (width
wise) stripe(s).
Causes:
This fault comes from yarn fault.
If different micro near value of fiber content in yarn.
Different luster, dye affinity of fiber content in yarn.
During spinning different similar classes of fiber is mixed specially in
carded yarn & these fibers have similar characteristics.
INDUSTRIAL INTERNSHIP REPORT SOUTHEAST UNIVERSITY
65 URMI Group
In draw fame different similar classes sliver is mixed and make one sliver.
Fly Dust:
Causes:
In knitting section too much lint is flying to and fro that are created from
yarn due to low twist as well as yarn friction. This lint may adhere or
attaches to the fabric surface tightly during knit fabric production.
Remedies:
Blowing air for cleaning and different parts after a certain period of time.
By cleaning the floor continuously.
By using ducting system for cleaning too much lint in the floor.
Over all ensure that lint does not attach to the fabric.
Yarn contamination:
Causes:
If yarn contains foreign fiber then it remains in the fabric even after
finishing,
If lot, count mixing occurs.
Remedies:
By avoiding lot, count mixing.
Fault less spinning.
Yarn Faults:
Naps.
Slubs.
Yarn count.
Thick/Thin place in yarn.
Hairiness.

- If pump pressure & reel speed is not equal
- Due to high speed m/c running
Remedies:
- maintaining proper reel speed & pump speed
- Lower rate rising and cooling the temperature
- Reducing the m/c load
- Higher liquor ratio
5. Dye spot:
Causes:
- Improper Dissolving of dye particle in bath
- Improper Dissolving of caustic soda particle in bath
Remedies:
- By proper dissolving of dyes & chemicals
- By passing the dissolved dyestuff through a fine stainless steel mesh strainer, so that the
large un-dissolved particles are removed
6. Softener Mark:
Causes:
INDUSTRIAL INTERNSHIP REPORT SOUTHEAST UNIVERSITY
95 URMI Group
- Improper mixing of the Softener
- Improper running time of the fabric during application of softener
- Entanglement of the fabric during application of softener
Remedies:
- Maintaining proper reel sped & pump speed

- Prevent the entanglement of the fabric during application of softener
Finishing:
The objectives of finishing operations are to treating textile product in to a presentable form.
Finishing process includes chemical and mechanical process. The extent of finishing process
depends on the fabric quality and the requirements of the finishing product. Finishing process
is employed for controlling fabric GSM, shrinkage, improving fabric appearance and to make
more lusters.
Objective of Finishing:
- Improving the appearance like Luster, whiteness etc.
- Improving the feel, this depends on the handle of the material and its softness, suppleness,
fullness, etc.
- Wearing qualities, no soiling, anti-crease, anti-shrink, comfort etc.
- Special properties required for particular uses water proofing, flame proofing etc.
- Covering the faults on the original cloth.
- Increasing the weight of the cloth.

Working Procedure of Stenter Machine:
The fabric is collected from the batcher to the scray and then it is passed through the padders
where the finishes are applied and some times shade variation is corrected.The fabric is
entered into the mahlo (weft straigtner) the function of the mahlo is to set the bow and also
weave of the fabric is griped by the clips and pins are also provided but the pins has a
disadvantage that they pins make holes at the selvedge but the stretchning of the pins are
greater than the clips.these clips and pins are joined to endless chain.there are 8 to 10
chambers provided on the machine each chamber contains a burner and filters are provided to
separate dust from air.the circulating fans blow air from the base to the upper side and
exhaust fans sucks all the hot air within the chambers. Attraction rollers ar provided to stretch
the warp yarn.

Compaction measurement:
Compaction measurement is doing for make a report of shrinkage for a fabric. How much
increase or decrease in length or width of a fabric after finishing is measuring by compaction
measurement.Fabrics have the tendency to shrink in washing, due to tensions introduced
during the spinning, weaving, knitting, dyeing and in some finishing operations.This
operation consists in applying chemical products or mechanical treatments(compacting,
sanforizing and stentering machine) in order that the clothing hasthe minimum dimensional
alterations after being manufactured.

3. Synthetic blanket as a conveyor
4. Folder
5. Exhaust fan
Heating system:Gas fired.
Utility:
1. Gas (to make fire)
2. Electricity (to rum the machine)
3. Compressed air (to spread the fire)
Working principle of dryer:
After de-watering then the fabric through the dryer. This machine contains two chambers.
Two mesh endless conveyors are placed lengthwise to the chamber named conveyor net and
filter net, each chamber contain a burner, which supply hot air .This hot air is guided through
the ducting line by suction fan .There are nozzles placed in between filter net and conveyor
net .When the fabric pass on the conveyor net, hot air is supplied to the wet fabric to dry it.
There are exhaust fan which such the wet air and deliver to the atmosphere through the
ducting line.
The speed of the dryer depends on the temperature of the m/c & the G.S.M of the fabric. If
the m/c temp. is high then m/c speed also high and the m/c temp. is low then m/c speed also
low . The vibration speed of the m/c for heavy fabric is 730 m/min and normal fabric is 480
m/min.

Cost Analysis:
Costing:
Costing of garment is a very necessary and important task. In this factory costing is carried
out by the merchandising department. Firstly, merchandiser contacts with the buyer and
collects order. Then he is provided a sample from sample section according to the buyer‟s
specification. The sample also supplies the fabric consumption. Cost of the fabric is
determined according to this consumption. Then he makes costing the other materials,
accessories, trimmings etc. He adds then all the production cost, Transport cost, Commission
(buying house, C&F agent) and profit.

Pattern making:
After receiving an order in most cases buyer gives them a complete pattern and they make
sample according to given pattern. But in some cases they prepare the pattern by own when
buyer don not give any pattern.
Marker making:
Marker is a thin paper which contains all the pattern pieces of a garment. It is made just
before cutting and its purpose is to minimize the wastages. The width of a marker is equal to
the width of the fabric and it should not be greater than the width of the fabric i.e. the width
of the marker is kept less than or equal to the width of the Fabric. The pattern pieces should
be placed very carefully in such a way that it will obviously minimize wastages.
Objects of Marker making:
To reduce cost;
To improve the quality of the garments;
To reduce the cutting time;
To facilitate large scale production

Work-study department:
This department evaluates, each apparel sewing line for planned output and actual output. If
the actual output is less than the planned output than on the shop floor executive of this
department do the case study and try to find out the reason and solution so that desire output
must come out fromsewing line. Following are the main tools of these departments;
INDUSTRIAL INTERNSHIP REPORT SOUTHEAST UNIVERSITY
128 URMI Group
1. Line balancing: - Sewing line must be evaluated after learning curve for time and
work balancing of each operator. If any unbalances observed because of the different
level of efficiency of different operator than after evaluation a new plan must be made
for smooth flow of work.
2. Method improvement: – For every sewing operation, plenty of method may be use.
Therefore for any bottleneck operation a new better method must be find out for
assisting or helping operator.
3. Trained and motivated employee: – For higher productivity this is an important tool
and company should start policies and schemes for trained and motivated employee.
For example „target with quality achieve incentive‟ etc.
Line balancing:
Line balancing is the allocation of sewing machine according to style and design of garment.
It depends of that what type of garment we have to produce.
The Objectives of Line Balancing:
Line balancing is a main part of a mass production. These kinds of systems, regardless of
being different in details, are workstations in a sequence. Row material is included in the line
at the beginning or in the middle. Parts included in the system transfers from one workstation
through the other and at the end leaves the system as a completed product. Transfer lines uses
manpower very little when compared to assembly lines. The certain properties of Transfer
lines are transfer and process of a product automatically through a line.
Objectives that should be gained balancing an assembly line are as follows;
Regular material flow;
Maximum usage of man power and machine capacity;
Minimum process times;
Minimizing slack times;
Minimizing workstations;
Maximum outputs at the desired timed;
Agreed quality maintenance of the garments;
Reduce production costs.
Importance of Line Balancing:
The importance of line balancing could be summarized as follows –
Good line balancing increases the rate of production;
This is the pre-condition for smooth production;
