Abstract:
Sewing process is one of the most important stages in labour intensive ready-made
clothing enterprises. Quality faults occurring during this process adversely affect
the
product quality and product efficiency, and also increase the production cost. The
aim of
this study is to investigate whether the knitwear production process is under
control in a
knitwear production enterprise and to detect the processes with highest rates of
sewing
faults in sewing department and finally to make suggestions for improving the
quality
control. Among the Statistical Process Control methods; control list, product
control chart
were used in the study. “product control chart” was used to test whether the
production
process is controlled in the enterprise. Furthermore, the statistical methods were
employed to determine the issues that need to be done in the improvement efforts
and to
detect the relations between the process groups supposedly effective on faults
occurring
in knitwear production and the amount of faults. Also, the processes with highest
amounts of sewing faults and the effects of these processes on fault rates were
investigated. As a result, it was concluded that the production process was
statistically

5. 5 P a g e
not under control in the ready-made clothing enterprise. In addition, this study
demonstrated that the investigation of each process group by drawing their product
control charts would make significant contributions to foresee the results and
prepare
more effective the improvement plans.

1.1Introduction:
Fabric is the core of apparel manufacturing. For this concern, many studies have
been carried out with the aim to reduce fabric wastage in the production process.
Cutting room is a place where a huge amount of fabric loss is generated. Fabric
loss in cutting room is mainly caused by two operations - marker making and
fabric spreading. Although marker making shares a large portion of material
wastage, fabric loss due to spreading is of equal importance for material utilization
control. Fabric also may wastage in knitting section during knitting process . On
the other hand , when a complete garments is made, then if any kind of fault which
cross the 4 point system , it also called fabric wastage.
1.2 Wastage and Fabric wastage:
wastage means to loss or damage something which are not reparable or re-useable.
When any material become loss or damage permanently and it loss its use ability
its called wastage. In textile , the main raw material is fabric . Fabric is produced
from yarn. By knitting process fabric is made . From fabric producing to finished a
complete garments product fabric may wastage.

10. 10 P a g e
Knitting section : In knitting section at Norban comtex ltd, 2-3% fabric is
wastage.
 Reason :
1) Design change: When fabric design is changed according to buyers fabric
construction machine set up have to change according to fabric design.
2) Machine set up: For new design of fabric , machine should be changed.
Machine parts also be changed. After changing machine set up when
machine is start for new designed fabric machine take sometimes for
controlled new design.
3) Machine maintenance: After a particular time machine should be
mainentnance . during this times oil and lubricants entered on the
machine parts and when machine is start oil and lubricant are attached on
the fabric surface which is the major fault of fabric and fabric is wastage.
4) Poor yarn used: Poor yarn is one of the most issue for fabric wastage .
Because poor yarn may be break down during machine running . If it
continue time and time it need time to re connect yarn and yarn become
wastage.
5) Machine R.P.M : Machine r.p.m may play an major role for fabric
wastage. If machine rpm is become higher against yarn count then yarn
may break down and may fabric wastage.
 Remedies :
1) Strong yarn used : For reducing fabric wastage strong yarn should be used.
2) Machine r.p.m and tension fixed: If machine rpm and tension is properly set
up then chance of yarn breaking is reduce and fabric wastage must be
reduce.
Dyeing section: In dyeing section at Norban Comtex ltd, 5-7% fabric is
wastage.
 Reason:
1) G.S.M measurement: In dyeing section fabric GSM should be check. That’s
why fabric is cut from fabric role by gsm cutter. Though it is legal to cut
fabric from any position of fabric roll, fabric is cut randomly and due to
miss positioning fabric is wastage.

11. 11 P a g e
2) In correct sample dyeing: before starting bulk dyeing, a short amount sample
is dyed as sample dyeing. If sample dyeing is approved first time then no
chance to fabric wastage.
 Remedies: Skilled worker should be used to check the gsm and skilled
engineer should be used to calculation recipe of sample dyeing.
Garments section :
 Cutting section : Maximum fabric is wastage in garments cutting section .
About 12-17% fabric is wastage in cutting section.
Reason :
1) Incorrect marker making;
2) Miss size ratio;
3) In correct cut panel;
4) Unskilled worker used.
Remedies:
1) Use Auto cad system;
2) Skilled worker used.
1.5 Fabric utilization:
It means how much fabric is being utilized in cutting for garment patterns out of
total fabric laid for cutting. Generally, fabric constitutes 60% to 70% of the total
garment cost. So, through effective fabric utilization factory can save lot of money
from fabric.
Calculation of Fabric utilization:
Fabric utilization is calculated by weight.
Step 1: Measure the lay length (A) or marker length that should be used in bulk
cutting. Suppose fabric width is 1.2 meters. Collect the information of fabric GSM
(Grams per square meter).

12. 12 P a g e
Step 2: Calculate weight of that lay (B).
Fabric Weight = Fabric width X Lay Length X GSM X No. of plies (You can also
calculate taking multiple lays) or 1.2A*GSM * no. of plies
Step 3: Cut the patterns and collect all waste fabric and weigh waste (C). Normally
includes ends losses, cut waste.
Step 4: Weight of the fabric of cut panels D= (B-C)
Step 5: Fabric utilization% = Weight of cut panels (D)/Total weight of the lay
(B)*100%
For the accuracy you can do this exercise with multiple lays and take average of
them.
Example: For better understanding I have shown an example in the following.
Step 1: Assume that
a) Measured lay length = 3 meters
b) Fabric GSM = 150
c) No. of Plies = 5 and
d) Fabric width = 1.2 meters,
Step 2: Calculated weight of the lay = 3*150*5*1.2 =2700 grams
Step 3: Weight of the collected waste after cutting = 300 grams
Step 4: Weight of the cut panels = (2700 – 300) = 2400 grams
Step 5: Fabric utilization percentage = (2400/2700*100) = 88.9%
1.6 Recommendation:

13. 13 P a g e
About 25-30% fabric is wastage during all process of textile. If its percentage is
reduced company will be more profitable.

Sewing fault analysis

2.1 Introduction:
Sewing is the craft of fastening or attaching objects using stitches made with
a needle and thread. Sewing is one of the oldest of the textile, arising in
the Paleolithic era. Before the invention of spinning yarn
or weaving fabric, archaeologists believe Stone Age people across Europe and
Asia sewed fur and skin clothing using bone, antler or ivory needles and "thread"
made of various animal body parts including sinew, catgut, and veins.
2.2 History
For thousands of years, all sewing was done by hand. The invention of the sewing
machine in the 19th century and the rise ofcomputerization in the later 20th century
led to mass production and export of sewn objects, but hand sewing is still
practised around the world. Fine hand sewing is a characteristic of high-
quality tailoring, haute couture fashion, and custom dressmaking, and is pursued
by both textile artists and hobbyists as a means of creative expression.
Seated woman sewing a kimono,Utagawa Kuniyoshi, early 19th century. Different
cultures have developed diverse sewing techniques, from methods of cutting fabric
to types of stitches.
Sewing has an ancient history estimated to begin during the Paleolithic
Age. Sewing was used to stitch together animal hides for clothing and for shelter.
The Inuit, for example, used sinew from caribou for thread and needles made of

15. 15 P a g e
bone; the indigenous peoples of the American Plains and Canadian Prairies used
sophisticated sewing methods to assemble tipi shelters. Sewing was combined with
the weaving of plant leaves in Africa to create baskets, such as those made
by Zulu weavers, who used thin strips of palm leaf as "thread" to stitch wider strips
of palm leaf that had been woven into a coil. The weaving of cloth from natural
fibres originated in the Middle East around 4000 BCE, and perhaps earlier during
the Neolithic Age, and the sewing of cloth accompanied this development.
During the Middle Ages, Europeans who could afford it
employed seamstresses and tailors. Sewing for the most part was a woman's
occupation, and most sewing before the 19th century was practical. Clothing was
an expensive investment for most people, and women had an important role in
extending the longevity of items of clothing. Sewing was used for mending.
Clothing that was faded would be turned inside-out so that it could continue to be
worn, and sometimes had to be taken apart and reassembled in order to suit this
purpose. Once clothing became worn or torn, it would be taken apart and the
reusable cloth sewn together into new items of clothing, made intoquilts, or
otherwise put to practical use. The many steps involved in making clothing from
scratch (weaving, pattern making, cutting, alterations, and so forth) meant that
women often bartered their expertise in a particular skill with one
another. Decorative needlework such as embroidery was a valued skill, and young
women with the time and means would practise to build their skill in this area.
From the Middle Ages to the 17th century, sewing tools such
as needles, pins and pincushions were included in the trousseaus of many European
brides.
Decorative embroidery was valued in many cultures worldwide. Although most
embroidery stitches in the Western repertoire are traditionally British, Irish or
Western European in origin, stitches originating in different cultures are known
throughout the world today. Some examples are the Cretan Open Filling stitch,
Romanian Couching or Oriental Couching, and the Japanese stitch. The stitches
associated with embroidery spread by way of the trade routes that were active
during the Middle Ages. The Silk Road brought Chinese embroidery techniques to
Western Asia and Eastern Europe, while techniques originating in the Middle East
spread to Southern and Western Europe through Morocco and Spain. European
imperial settlements also spread embroidery and sewing techniques worldwide.
However, there are instances of sewing techniques indigenous to cultures in distant
locations from one another, where cross-cultural communication would have been

16. 16 P a g e
historically unlikely. For example, a method of reverse appliqué known to areas of
South America is also known to Southeast Asia.
2.3 Elements of garment sewing
Sewers working on a simple pattern need only a few sewing tools: measuring tape,
needle, thread, cloth, and sewing shears. More complex patterns done on a sewing
machine may only need a few more simple tools to get the job done, but there are
an ever-growing variety of helpful sewing aids available, such as presser
foot attachments for sewing ruffles, or hem repair glue.
When the sewer has gathered the necessary tools to tackle a pattern, there are
several elements of garment construction that are part of the process. Patterns will
specify whether to cut on the grain or a bias cut.
Construction stitches include edgestitching, understitching,staystitching and topstit
ching. seam types include the plain seam, zigzag seam, flat fell seam, French seam,
and many others. Supporting materials, such as interfacing, interlining or lining, or
fusing, may be used as well, to give the fabric a more rigid or durable shape.
Volume can be added with elements such as pleats, or reduced with the use
of darts.
Sewing machines are now made for a broad range of specialised sewing purposes,
such as quilting machines, computerized machines for embroidery, and
various sergers for finishing raw edges of fabric.
2.4 Sewing Faults
Quality of product plays an important role in any industry. If a consumer does not
like the quality of the product then the chances of sales become very less. Today,
clothes play a very important role in the society. They help in creating an
impression and define the human being in some aspects. Therefore it is very
important to see to it that garments are made of high quality. In textile and Apparel
Industry, sewing is one of the major processes in apparel production. It plays an
important role in maintaining the quality of clothes. Hence it is important that all
defects have to be avoided during sewing any apparel. In this paper, various faults

17. 17 P a g e
or defects that can take place during sewing along with different remedies or
methods to solve these defects are discussed.
2.5Types of Sewing Faults:
Mainly there are three types:
1. Critical fault.
2. Major fault.
3. Minor fault.
Critical fault: The faults present in garments lead the garments to be rejected
directly are called critical fault. This garment should not pass for shipment.
Example:
a. Hole in the garments.
b. Shade variation of the garments fabric etc.

Major
faults
Minor
faults

18. 18 P a g e
Major fault: The faults which are present in garments may not lead the garments
be rejected rather after removing this faults garments are executed for shipment is
called major fault.
Example:
a. Spot in the front part.
b. Seam puckering.
c. Slipped stitch.
d. Broken stitch etc.
Minor fault: The faults which are present in the garments cannot lead the
garments be rejected rather if small quantity of this fault are present in the garment,
garments can be accepted for shipment. This type of fault is called minor fault.
Example:
a. Spot in the under part.
b. Sewing problem in the under part etc.
2.6 Names of different sewing faults , reason and their remedies :
Fault name: Gathering
Causes:
 Size matching: When different parts of the body are not matching with
another parts , during stitching gathering may occurred .

Remedies:
 Operator should be careful to join level;
 Operator helper should be check all parts before passing other to another.

21. 21 P a g e
Figure: Level missing.
Fault name: Shade variation:
Causes:
 Mismatching of body parts;
 Lot or bundle of cut panel mixing ;
 Miss mixing of face side and back side of body parts.
Remedies:
 Recheck bundle or lot before input in sewing line;
 Proper identified of face side and back side;

22. 22 P a g e
Figure: Shade variation.
Fault name: Skipped stitch:
Causes:
1. Failure of needle to enter loop at correct time
2. Needle deflection or bent needle
3. Thread loop failure due to incorrect needle size for thread size
4. Incorrect sewing tension in the needle
5. Thread loop failure due to incorrect setting of thread control mechanism
6. Flagging of fabric due to poor presser foot control

23. 23 P a g e
Remedies:
1) Check needles is inserted and aligned correctly. Machine clearance and
timings.
2) Replace the needle
3) Change needle size in accordance with thread size. Kindly refer to
recommended needle numbers against specified articles.
4) Re adjust the thread tension
5) Reset to standard and check loop formation through jog mechanism.
6) Re adjust presser foot pressure
Figure: Skip stitch.

24. 24 P a g e
Fault name: Seam Puckering:
It may be defined as a ridge, wrinkle, or corrugation of the sewn fabric running
across the seam. It is a sort of differential contraction occurring along a particular
line usually along the seam line, in fabric,
Seam Puckering can be attributed to following causes:-
Incorrect tension setting
Structural jamming or inherent pucker
Fabric and / or thread instability
Poorly controlled fabric feed
Extension in sewing thread
Diagnosis
Without distorting the thread loops in the fabric, cut entire top and bottom threads
of all the stitches along a fixed length of the seam. If the pucker vanishes, then it is
due to incorrect thread tension setting.
If pucker does not vanish then remove the stitches. on removal if both faces of
seam come to a normal surface, structural jamming has occurred.
If pucker appears after during post sewing operations or washing, due to
dimensional changes in the thread /fabric. It is due to fabric /thread instability.
Cut the area of maximum pucker, if on removal of stitch, one ply of fabric is
longer than the other, then it is due to poor control on feed.

25. 25 P a g e
Incorrect Tension Setting - tension setting
Sewing with too much tension in thread causes pucker sewing takes place in
stretched state of the thread. After sewing the stretched thread relaxes and attempts
to recover its original length, it gathers up seam, which causes pucker.
Remedies:
Check tension level in the thread, Sew with minimum tension possible. Always
adjust bobbin thread tension first then needle thread tension.
Check dirt / fIy accumulation in the thread guides and eyelets. Check rough or
worm out hread guides.
Check if the coefficient of friction of the thread with metal is high. Contact
Customer Technical Service Cell.
Adjust feed timing and fabric control for maximum pulling of the fabric.
Check for proper threading or fitting of bobbin case.
Fault name: Needle Thread breakage:
CAUSE:
1. Excessive tension in needle thread
2. Thread fraying at needle
3. Thread trapped at thread guide
4. Thread trapping at the base of cone
5. Snarling before tension disc.

26. 26 P a g e
6. Improper off winding from cone
7. Sharp edges on throat plate, hook point, needle guard, bobbin needle groove or
eye.
8. Excessive needle heat, groove or eye blocked with melted fabric.
Remedies:
1) Use stronger thread or adjust tension
2) Use finer thread or coarser needle
3) Re guide the thread properly
4) Reduce cone stand height to avoid vibration which can cause thread trapping
5) Increase thread guides and reduce disc tension
6) The overhead guide should be directly above cone or the thread package.
Also ensure that thread package shouldn’t get tilted during off winding.
7) Polish rough edges, replace. Replace needle, use better quality.
8) Change to better needle or throw compressed air to cool down the needle.
Fault name: Open seam or broken seam
Causes:
This happens due to improper handling of the parts of garments , improper setting
and timing between needle and looper or hook etc.
Remedies:
Proper setting and timing between needle and looper or hook.
Proper handling of the parts of garments.

27. 27 P a g e
Fault name: Cutting hole:
Causes:
 Carefulness of helper during cutting sewing thread ;
Remedies:
 Helper should be careful during cutting extra sewing thread ;
 Thread cutter should be keep in safe place;
Figure: Cutting hole.

28. 28 P a g e
Fault name: Oil mark.
Causes:
After maintenance the sewing machine it contain oil or lubrication on its
out surface and during sewing it mixed with the fabric surface.
Remedies: After oiling or lubrication the machine, machine should be clean with
jut fabric or others.
Fault name: Sewing thread shrinkage
Causes:
 Due to variable shrinkage % of sewing thread & fabric, Seam pucker will
create after washing or ironing.
 Cotton threads develop puckering when wet or after wash.
Remedies:
 To use synthetic thread.
 To protect this, it must know about the shrinkage % of fabric & thread
before selection to sew.

29. 29 P a g e
Fault name: Size measurement.

CONCLUSION
Finally we have completed our thesis after lots of inspection, experiment &
discussion. We have gathered a large experience about this project. We have
increased our knowledge about how sewing is done, problems of sewing & how
those problems are minimize. This study investigated knitwear sewing process in a
ready-made clothing Enterprise manufacturing men’s suit in terms of quality; in
addition, the reasons increasing quality faults and the priorities were determined
for the improvement studies. During data collection, the sewing faults were
determined in 4.5% products. As a result, the knitwear production process was
concluded statistically not under control in the enterprise. In addition, there was a
statistically significant relation between the quality fault amounts. In the present
study, it is established that Statistical Process Control Methods could be suggested
for planning improvement studies and analyzing whether the quality is under
control in a ready-made clothing enterprise. In addition, it can be suggested to
prepare separate (p) control charts for all process groups contributing to fault
reasons and to investigate hypothetically the effects of improvement studies on
quality level. Within the scope of quality improvement studies, it could be

36. 36 P a g e
recommended to make regular quality control education, to investigate permanent
solutions instead of daily solutions, to keep the workers’ motivation high, and to
make regular maintenance of machines. To enable a good quality system in
enterprises, there should be adequate number of quality staff and the quality
consciousness of workers should be increased. Quality system includes all the
phases of production from the input of materials to product output, and quality
standards should be created. Material quality should be controlled by performing
input controls, while production quality should be provided by intermediary
controls during production, and product quality should be provided by making
output controls in the enterprise. Quality level should be constantly improved by
using SPC methods, and for this purpose, regular trainings should be prepared in
the enterprise
