3.1 INTRODUCTION:
Sampling is basically the process of producing some prototype garments in order to match the
various buyer requirements such as the design features, size, style etc. As soon as any order is
received the tech pack and requisition form is handed over to the sampling department and
various samples of the product are developed in order to get the orders confirmed from the
buyer.
CAD Department
Garment sampling is a very important task in an apparel manufacturing because if the buyer
is not satisfied by the samples, this puts the following at risk:
30. 21
- Placement of the order
- Acceptance of the some or the entire quantity of garments produced.
When the product is in the sampling stage, the buyer might suggest few alternations or
changes as per the appearance and fit of the garment and the requirement of the style.
In these stage, the company checks the feasibility of the garment whether it is affordable or
not and whether the company has the required machineries to do the operations to make that
particular style of garment or not.
Though sampling is a costly procedure but it identifies the various problems which might be
faced during the bulk production.
Also this department is responsible for patterns and markers to be made for all the orders.
3.2 OBJECTIVE:
- To allow the buyer to judge the production capabilities of the manufacturer.
- To provide a means for making revisions in the bulk production process.
- To let the manufacturer estimate the thread and fabric consumption, and develop cost
quotations.
- To develop efficient patterns and markers.
3.3 DIFFERENT TYPES OF SAMPLES:
GENERAL SAMPLES SAMPLES MADE IN UTAH (UKDLW)
- Development sample
- Fit/Proto sample
- Coordination sample
- Salesmanship sample
- Fit sample
- Photo shoot sample

33. 3.5 PROCEDURE
In this department, there are mainly two sub divisions i.e.
PATTERN MAKING Section consists of pattern making and grading, marker making
and printing the pattern and cutting of that pattern. The marker making section works
in similar manner for bulk production also.
SAMPLING Section consists of cutting, sewing, trimming inspection etc. sub-
sections. In the cutting section, manually patterns are transferred on the fabric and
fabric is cut accordingly by cutters. Sewing section is the sub-section the cut parts of
the fabric are stitched and become a full garment. Trimming section is the sub-section
where the garments are trimmed after wash and trims are attached to it. Inspection
area is the sub-section where checking is done twice by QA personnel, once before
wash and again after wash. The washing of samples is done in the washing
department. Then after finishing and packaging of the samples they are sent to buyer
through merchandiser for buyer’s approval.
3.6 PATTERN MAKING SECTION:
In this section, the pattern masters are asked to make pattern as per the buyer requirements.
From pattern making to printing, the company uses the CAD software. There are two types of
buyers –
- One who provides the pattern block and tech pack which consists of all the detailed
information about the garment (style, measurements, fabric details, trim details,
shrinkage% etc.), this type of pattern is called buyer block. Only reputed buyers like
H&M send the buyer blocks to the company and for this type of block the pattern
master needs not to change the pattern and they only do grading and make marker of
the patterns and get the print out.
Fig: Printed bulk patterns for different garments.
34. - Buyers who give only the measurements in the form of spec sheet and tech pack
where they only mention about the fabric and trims details as well as the style. For
these types of patterns, the pattern masters have to make the patterns by CAD
software with the given measurements by the buyer given. And for these types of
buyers, the department do shrinkage test and give the details to the pattern masters.
According to that shrinkage % the masters changes the patterns.
Sometimes, some buyers provide wrong measurements, for that the company gives some
suggestions to that buyers and after discussion; the buyers accepted the proposed tech pack or
process given by the company.
3.7 PROCEDURE
The Software used for making patterns and markers are in CAD are:
A. GERBER TECHNOLOGY(ACCUMARK Pattern Design Software):
It is the mother software which is being used since the origin. It is windows based software;
satisfy their most demanding design and production requirements.
B. SHRINKAGE ALLOWANCE:
After receiving the fabric, it goes for shrinkage test. According to the shrinkage test report,
allowance is put in the pattern before finalizing the pattern for further processes.
C. GRADING:
After pattern making, the grading is done to the patterns. Grading is the process of creating a
range of sizes for a single style. Grading a pattern is a way of sizing a pattern up or down
while maintaining the proportions of the original pattern.
Fig: Grading of pattern in GARBER software
35. D. MARKER MAKING:
A marker is a diagram of a precise arrangement of pattern pieces for different sizes of
garments for a specific style of garment that are to be cut out from one spread. Marker
making is the process of determining a most efficient layout of pattern pieces for a style,
fabric and distribution of sizes. Marker making is done by CAD systems which gives
accuracy, increase control over variables and reduces time required in making markers. The
efficiency of marker making in the CAD section is 85% - 87%. Size set marker consists of
different size of same style of garment. For different type of appearance of fabric, they use
different markers like solid marker (one way, two way directions), stripes, checks, colors.
In case of manual marker or when marker is given by the buyer, the pattern is placed on

E. PLOTTING:
The plotter is a computer printer for printing vector graphics. Plotters were used in
applications such as computer-aided design. A plotter gives a hard copy of the output.
It draws pictures on paper using a pen. After getting the marker request from the maker
making section, they give the allowances and put the details about the fabric like GSM, style
no. etc. on the pattern block and print it by the plotter. In this section, there are two types of
plotter.
36. Fig: WinDa pattern plotter and cutter
One is used only for print the markers. And the other one is the automatic cutter plotters
which prints the marker and cut the patterns simultaneously which are used in cutting section
of sampling department. Sometimes the patterns are cut manually also.
Fig: WinDa Marker printer
37. 3.8 SAMPLING SECTION:
A. SAMPLING CUTTING SECTION:
After printing the patterns, they are sent to the cutting section of sampling department. Here,
the designated personnel check the measurements of the patterns and match it with the
sample indent. The fabrics in small amount are then issued as per the requirement. After that
the fabrics are kept for fabric relaxation to maintain the dimensional stability of produced
garments. After that the cutter spread the fabric manually for cutting and places the pattern on
it. The length of the lay will be depending on the no. of patterns and the length of the patterns
of a single size of a particular style of garment. The no of lay depends upon the type of fabric,
requirements of samples by the buyers etc. After spreading manually, they trace the pattern
on the fabric and cut accordingly by using straight knife. During cutting, they also cut the
notch marks. After that the parts are sent for sewing.
B. SAMPLING SEWING SECTION:
When the fabric is cut, the next process is sewing. For sewing the modular system is being
used here. A team of operators is producing the full garment i.e. they are attaching all parts of
the garment and for specialized technique they go for other special machines.
C. LOADING PLAN:
This is a plan given to the sewing dept. for the stitching purpose. According to the loading
plan, the supervisor assigns the jobs to the workers and then stitching is done.
Fig: Sampling Sewing Section
After all the operation, the garments are then trimmed and sent to washing department for
washing of garment to get desired shade and style specified by the buyers. After washing of
the garments, those are again sent to the sampling department for further processing.
38. D. SAMPLING TRIMMING SECTION:
After washing, the samples are returned to finishing section of sampling department. It is also
referred as trimming sections. Here the threads are trimmed from the garment. And the rivets,
shanks, buttons, tags etc. are attached to the garments. After that, the garments are sent to the
inspection area for quality checking.
E. SAMPLING INSPECTION SECTION:
After stitching, the garments are sent to the inspection area for stitching quality-check of the
garments. The quality checkers inspects the garment and matches it with the sample indent. If
there is any problem in stitching or cutting or measurements, then respective corrective
actions are taken. If the samples are ok, thenthey are sent for washing.
After washing, the samples are again returned to the sampling department for trimming and
after trimming the garments are sent to inspection area again for checking. The checkers
check each and every detailing of the garment like shade %, measurements etc. 100%
checking of the samples are done here.
The quality parameters checked here:
- Measurements
- Grain line
- Sample indent information
- Shade
- Shrinkage %
- Tech pack
- The placement of the panels
- Pockets, zippers, buttons, rivets, tag etc.
- Small details about that particular style.
After all the procedures, the samples are sent to the merchants along with the patterns and
whole tech pack and merchants send the samples to the buyers for approval.

POSSIBLE STANDARD OPERATING PROCEDURE FOR SAMPLING
DEPARTMENT:
PURPOSE:
The most important part of garment manufacturing is sampling. The sampling department
must be very precise and efficient. All the departments in sampling section should have a
series of quality checks and inspections. The series of samples created according to the
buyers’ requisition should be sent to the buyers after particular interval of time. The buyers
comment should be given the most priority, which would be communicated by the
merchandiser with the help of a requisition form. No alteration should be done in any of the
step independently by the department without buyers’ approval. To be precise if the sampling
is not done properly by the department, and then there is a high chance of operation error in
the process, which can even lead to cancellation or withdrawal of order.

-
PROCEDURES:
1. The buyer specifies the sample, fabric and quantity in the requisition form, which is to
be received by the concerned merchandiser.
2. The buyer also provides a specification sheet where all the details about the
measurements, style, and sketch of the product are mentioned.
3. Immediately after reception of requisition form and specification sheet the
merchandiser sends it to the respective sample departments.
4. At the beginning stage the development sample is being produced.
5. Raw material is procured by the merchandiser and sent to the sampling department.
6. The sourced fabric, trims and accessories should be inspected by the concerned
inspection departments and inspection report is generated by the concerned
department head with his signature.
7. In case the pattern is sent by the buyer, then all the pattern parts must be verified by
the CAD/CAM in charge along with QA personnel and if there is any variation, then
it is to be informed to the relevant merchant through buying office/merchandiser and
hence the variation should be corrected. No one else has the authority to alter the
pattern without the head of QAM and buyer’s approval.
8. If the pattern is to be made in-house, then the specifications sheet is analyzed and sent
to the pattern making team or the CAD team.
9. The pattern masters develop block pattern with the help of CAD. The patterns should
be cross checked by themselves in the software itself in reference to the spec sheet.
10. Shrinkage allowances inspection report should be given by concern fabric inspection
department head with his signature.
11. The pattern masters should develop main pattern with the help of CAD along with
shrinkage and seam allowance. The patterns should be cross checked in the software
itself in reference to the spec sheet (pattern accuracy check).
12. The patterns are then printed and cut by the automatic pattern printer and cutter.
13. Patterns are checked by assigned QA personnel and if the pattern is satisfactory
according to the spec sheet by buyer, then the QA personnel along with the sampling
43. department in charge grants it for further processing by signing together with the
CAD in charge and granted to the cutting department.
14. After the pattern gets approved for cutting, raw material should be issued along with
signature of receiving and issuing authority.
15. The concern sample cutting personnel receives the patterns (mini marker) and the
fabric is cut accordingly with scissor. But sometimes if the lay is quite high, then a
hand held straight knife is used.
16. The cut out pattern parts are matched with the original patterns and checked for frayed
edges and other cutting defects by QA personnel.
17. If the cut parts are acceptable, then the cut parts are issued for embroidery or printing
(if necessary) along with signature of issuing and receiving authority.
18. After receiving the cut parts with embroidery or printing should be inspected or
checked by QA personnel and if it is okay, then it is signed and approved for sewing.
19. Sewing teams consisting of 3-4 operators with different skill sets should be formed
according to the complexity of the styles. The operators must be instructed thoroughly
about the sequencing and the operations involved in it.
20. Constant supervision and in-line inspection to be done at regular interval of time. In
case of any defect, it has to be spotted and rectified then and there if possible.
21. After the production of market sample, the product is inspected by the QA inspector
and if it meets the requirements of the buyers spec sheet, then it is packed and to be
sent to the merchandiser followed by the buyer.
22. The buyer checks the sample and reply with their comments on the sample. If
approved, further processes are followed or the same process is repeated according to
the comments.
23. Then according to buyer’s requirement, market, salesman sample are made following
the same process with variation in quantity and necessary requirement by buyer.
24. Followed by fit and pre-production sample, in which block pattern is not made and
the samples produced should be very much specific.
25. If all the above mentioned samples are approved by the buyer, then the preparation for
pilot run is initiated. In which the marker is made by the CAD department and
verified on the software by the pattern maker and printed.
26. The marker which is printed should be matched with the patterns and spec sheet by
QA and if everything is fine, then the marker is signed by QA personnel and is
approved for bulk cutting (marker inspection).
27. After the fabric is laid in the spreading table, a spreading inspection must take place
where fabric tension, selvedge, face side, table marks etc. will have to be inspected.
28. Then the approved marker will be placed on top of the lay and will be made ready for
auto cutting.
29. The soft copy of the approved marker will be transferred to the CAM and then a CAM
marker inspection will take place where the inspector will see the printed marker
placed on the fabric is same as the soft copy provided in the CAM.

51. 4.1 INTRODUCTION:
Spreading is the process of superimposing lengths of fabric on a spreading table, cutting table
or specially designed surface in preparation for the cutting department. A spread or layup is
the total amount of fabric required by a single marker.
Fig: Spreading by spreading machine
After fabric relaxation for 24 hours, the fabric is then spread on the table according to the nap
direction of the fabric. The marker is spread over the lay and after that cutting is done. The
laying is done shade wise.
4.2 OBJECTIVE:
- To lay the fabric in correct order.
- To check the parameters of fabric lay.
- To minimize fabric wastage.
- To prepare the lay of fabric properly for cutting.
4.3 PROCEDURE:
As spreading is one of the important processes in any garment manufacturing industry, so, it
needs to be done with proper care. If there is any problem in spreading then it will continue to
cutting. And if the fabric is cut with the defect then the cut panels will be wasted resulting
increasing the manufacturing cost of the garment. The planning department sends cut plan to
the department. And following this cut plan, spreading is done accordingly.
52. Spreading procedure consists of the following sub-processes.
- Fabric relaxation
- Spreading
- Marker Spreading

53. A. FABRIC RELAXATION:
When the fabric comes from the buyer (to be specific
from dyeing and finishing) fabric may remain slightly hot
(As in dryer. stenter, and compactor, heat is applied to the
fabric). So moisture is removed from the fabric and it is
not in its actual condition. But if we keep the fabric in
normal condition for a certain time, the fabric absorbs
moisture from the atmosphere and regains its original nature. This process is called fabric
relaxation.
Fig: Fabric Relaxation Machine
Another reason for fabric relaxation is to maintain dimensional stability of produced
garments. When the fabric is being processed in different finishing machines, it goes under
certain heat and pressure to give it proper shape. But when the heat and pressure is
withdrawn, the shape may change. So if the dimension is become stabilized before cutting, no
chance of strain in garment. So relaxation is very necessary before cutting.
RELAXATION PERIOD:
Relaxation period may vary for different fabrics. But the minimum time for relaxation is 12
hours. But it may vary according to the buyer’s requirement.
B. SPREADING:
A spread may consist of single ply or multiple plies; the weight of the ply is limited by fabric
characteristics, size of the order to be cut, cutting method and vertical capacity of the
spreader. End cutters are used for spreading in case of manual spreading.
Spreading could be two types.
- Manual Spreading, which is the traditional way of spreading.
54. Fig: Manual Spreading
- Spreading by auto spreader which is an automatic machine to lay the fabric faster than
manual spreading.
Fig: Spreading by spreading machine
PROCEDURE:
Spreading procedure could be divided into two segments-
- Pre-spreading procedure
- Spreading procedure
PRE-SPREADING PROCEDURE
1. It should be checked if the fabric shade and batch wise fabric shade is approved or
not.
2. Fabric shrinkage group and shrinkage report should be collected.
3. Quantity of shade variation in a fabric lot should be known and shade band should
be collected.
4. It should be checked whether the marker for bulk production is approved or not.
5. The GSM of fabric should be known and checked according to buyers’
requirement.
55. 4.5 SPREADING ROCEDURE:
1. The Pump sheet (a thin perforated brown paper to prevent the bottom plies from
shifting during cutting) is spread on the vacuum table.
2. Table marks should be made on the pump paper according to the size of the
marker.
3. The fabric is then loaded onto the auto-spreader, in such a manner that the face
side is up.
4. Then an inspection of the dimension (length and width) of the marker with the
fabric is done by placing it on two lays of fabric.
5. Then the fabric is spread lay by lay on the spreading table by the auto-spreader.
6. Meanwhile for each lay, uniformity of each lay, orientation of the lays, selvedge,
narrow width and corner of the fabric should be checked to avoid unwanted
curling of fabric.
7. Marker should be placed in top of the plies and placement of the marker should be
checked considering the table marks
8. Height of the plies should be according to the buyers approved height of lays.
4.6 RESPONSIBILITIES OF QUALITY DEPARTMENT IN SPREADING
Quality inspector and quality controller should be aware of the following check points in
spreading.
- The length and width of the Pump paper should always be more than that of the
marker.
- Table marks must be made on pump sheet.
- Face of the fabric should always be upside.
- It should be checked if the fabric is in correct lay or not and if there is any joint in the
fabric. If found, then it should be checked to know whether they are similar for both
the fabric.
- At the end of fabric lay, total noof plies must be counted at both the ends and must be
same at both the ends.
- For each lay, uniformity of each lay, orientation of the lays, selvedge, narrow width
and corner of the fabric should be checked to avoid unwanted curling of fabric.
56. - Lay height depends on the thickness of the fabric and the capacity of the cutting
machine on the thickness of the fabric and the capacity of the cutting machine. So it
must be accurate and according to buyer’s recommendation.
4.7 IMPORTANT RECORDS MENTIONED BY CUTTING DEPARTMENT:
A. ROLL ISSUE REGISTER:
It is a register mentioned by the cutting department to keep a record of the fabric rolls
received for cutting from warehouse. The records are mentioned according to job no., cut no.
etc.
B. LAY CHART:
It is a report prepared to keep record of the fabric roll being layed, length of lay, total
length of fabric, no. of lays etc. It gives a proper idea about the materials handled while
spreading.
4.8 MAJOR DEFECTS:
A. PLY ALIGNMENT:
Accuracy with which fabric edges, both length and width are aligned during
spreading.
B. SLACK TENSION:
It occurs if it contains excess fabric in each ply. In cutting, a slack spread may create
over sized pieces. It causes in accuracies in assembling and waste fabric.
C. STATIC ELECTRICITY:
It is the result offriction between materials and spreading equipment. Fabrics from
manufactured fibers may have static problems.

Sewing Machine
Raihan Apparels LimitedTotal sewing m/c 1694 pcs. .Manpower about 2990. After cutting
fabrics, these are sewed in here by different kinds of stitch with different kinds of sewing
machine. Trims are also sewed here with RMG. All kinds of sewing are done here.
Sewing second:
They have one main sewing floors. At the 2th floors of the factory we visited the among sewing
section. There are 8 lines per lines 1 in line quality controller & 2 product checkers and per unit
1 quality executive. They use box between every machines to keep the fabric dust free.
They follow traditional sewing system that means sewing line being controlled by the quality
inspector & quality supervisor.
63. Sewing is the most important step of garments manufacturing. Sewing means the joining of
garment components with the help of needle and thread. It is the dominant process of garments
assembling and still the best way of achieving both strength and flexibility in seam as well as in
manufacturing method.
The objectives of the stitching department are
The cost minimization and
To minimize wastage
Best utilization of time
Quality control by line checker

Before starting the sewing in the line of the new style it has to be conduct pp meeting to avoid
the missing of buyer comments or requirement.
Label Check:
AQC check the label against trim card & give the permission to start the sewing.
Sewing Start:
It is mentioned that sewing will start by size wise which size quantity is huge.
During Sewing:
Supervisor & Line-chief doing the major job during the sewing.
They always try to solve the up-coming problem.
65. Maintain the hourly production with right quality.
Output:
After doing all process and quality check garments will store in output table.
Reporter will collect the garments from output table.
After collecting the garments, reporter will count and delivery the goods in finishing section by
size wise.
5.3 SEWING DEFECT FAULT
Stitch, seam, feed mechanism, needle and thread together determine the seam appearance and
performance. The problems which arise when materials are sewn vary in their seriousness.
Some are major problems which can not be overlooked and for these problems garments will be
rejected by the inspector, where as some are minor problems which are negligible in low quality
garments.
The problems are most conveniently divided into:
1. Problems of fabric distortion known as seam pucker which give rise to poor seam
appearance.
2. Problems of stitch formation which also give rise to poor seam appearance and performance.
3. Problems of damage to fabric along the stitch line.
1. Seam pucker.
2. Broken or open stitch.
3. Staggered stitch.
4. Slipped stitch or skipped stitch.
5. Variable stitch density.
Of them the first two are major problems and the rest are less serious problems.
66. 1. Problems of Seam pucker:
Seam pucker is a major problem. Pucker is a wrinkled appearance along a seam when compared
to a smooth fabric.
The main causes of seam pucker problem are mentioned below-
A) Mainly seam pucker occurs due to unequal tension of feed dog and pressure feet on
Two plies of fabric.
B) It also occurs due to unequal thread tension and unsuitable thread.
C) It may occur due to feeding problem and needle size.
D) It also occurs due to shrinkage of either fabric or sewing thread.
E) It may occur due to instability of fabric dimension or fabric construction.
The steps that may be taken to reduce seam pucker problem
By using finer thread and fine needle seam pucker problem may
Be reduced.
B) By adjusting proper tension and pressure of feed dog and pressure feet on fabric plies, it can
be removed.
C) By using unshrinkable sewing thread and fabric it can be minimized.
D) By reducing the stitch density it can be reduced.
E) In chain stitching, seam pucker occurs less frequently.
F) By using two plies of fabric with same shrinkage rate seam pucker can be minimized.
2. Problems of stitch formation:
A. Broken or Open stitch:
It is also a major problem of sewing. The reasons of occurring broken or open stitch are
mentioned below –
67. Mainly, due to the breakage of needle or bobbin or looper thread in high speed sewing. This is
responsible for broken or open stitch.
A) Needle thread breakage occurs due to following reasons –
I. If tension on needle thread is more.
Ii. If snarling of yarn occurs in tension disc.
Iii. If fraying of needle thread occurs.
Iv. Excess needle heating or hook heating.
V. Low quality sewing thread.
Vi. Sharp edge of throat plate, hook of bobbin cage, needle groove etc.
B) The causes of bobbin or looper thread breakage are mentioned below –
I. Faulty winding of thread on bobbin.
Ii. Excessive tension on bobbin or looper thread.
Iii. Sharp edge of bobbin cage, looper eye, and spring.
Iv. Faulty fitting of bobbin cage.
The remedies of this problem are-
A) Adjusting proper tension of bobbin and needle thread.
B) Proper unwinding of thread from package.
C) Removing sharp edge of machine parts.
D) Using good quality strong sewing thread.
B. Staggered stitch:
If the stitches produced by needle are not parallel with the seam line individually they are called
staggered stitches.
The causes of staggered stitches are mentioned below:
68. A) Due to needle deflection and vibration.
B) Due to loose fitting of needle butt inside the needle bar.
C) Due to wrong selection of needle point.
D) Due to combination problem of needle and thread size.
E) Due to faulty speed and motion of feed dog.
F) Due to improper controlling of fabric by the feed mechanism.
The remedies of staggered stitches are as below:
A) Assuring tight fitting of needle inside the needle bar.
B) Adjusting needle point and thread size properly.
C) Adjusting the motion of feed dd) Adjusting the pressure of pressure foot.
C. Slipped or skipped stitch:
If the continuation of stitches in a seam line is hampered by slipping some stitches it is called
slipped or skipped stitch. If the looper in the machine can not pick the loop of needle thread
from the underside, slipped stitch arises.
The causes of slipped stitches are mentioned below:
A) If timing between needle and looper or bobbin is not proper, needle thread loop is not picked
up by bobbin thread loop when required. This will cause slipped stitch.
B) If the loop of needle becomes smaller in size slipped stitch occurs.
C) Unequal tension between the two sets of thread.
D) Deflection or vibration of needle.
E) Due to flagging during sewing.
The remedies the problems are –
A) The timing between needle and looper should be adjusted properly.
B) Needle and thread size should be adjusted.
69. C) Pressure feet and throat plate should be adjusted.
D) Needle thread tension should be proper.
D. Variable stitch density:
It is the variation of number of stitches per unit length of seam. The causes of variable stitch
density are mentioned below:
A) If fabric cannot move forward properly due to lack of pressure of pressure feet.
B) Due to faulty feed mechanism. It can occur particularly with materials with sticky or slippery
surfaces.
The remedies of the problem are –
A) Adjustment of pressure feet pressure.
B) By using specialized feed mechanism it can be minimized.
E. Unbalanced stitch:
These types of faults are found mainly in lock stitches. If the interlacement of needle thread and
bobbin thread is not occurred at the middle of two plies of fabric then unbalanced stitch is
formed.
The causes of unbalanced stitches are-
A) If the tension of thread is not accurate.
B) If sewing path is wrong.
C) Faulty settings of bobbin.
D) If lubricant is not used in the thread.
The remedies of the problem are-
A) The tension of thread should be accurate.
B) Thread path should be accurate.
C) The settings of bobbin should accurate.
70. D) By using good quality thread.
3. Problems of damage to the fabric along the stitch line.
A) Mechanical damage:
1. Needles can strike and break fabric yarns and burst the loops in knitted fabrics. For this
appropriate set and ball point needles are necessary.
2. Needles should always be as small as possible.
3. Sometimes the combination of the machine speed and nature of the fabric prevents the yarns
from moving out of the way of the needle sufficiently fast to avoid damage .To solve the
problems either reduce the speed which means lesser production or ensure that the fabric is
adequately lubricated. It calls for having resin finish on the fabric.
B) Needle Heating Damage:
Needles heating occurs as a result of friction between the needle and the fabric being sewn.
In high speed sewing of dense material, temperatures as high as 3000or even 3500c can be
reached.
72. 6.1 Finishing and packing
In production Department garments are stitched by sewing machines. Stitched
garments are finished in the finishing department. Finishing activities are performed
prior packing garments into poly bags. The major activities of a finishing department
include thread trimming, checking garments and ironing.
Work flow chart of finishing and packing section
73. 61
6.2 Activities of the finishing department are listed below
1. ThreadTrimming:
In stitching department thread trails and thread chains are not trimmed neatly. Uncut threads and
thread tails in garments are trimmed in the finishing department by helpers. Uncut and loose threads
on garments are considered defects.
2. Checkinggarments:
All garments are checked at the finishing stage for visuals and measurement. Finishing checkers
check the complete garment inside and out. Checking is done for garment detailing, such as care
labeling, and trims.
3. Button attach and Buttingholing:
Products those have trimming like button, snap button, eyelets are attached in finishing section.
4. Removingstains:
Stains and spots are found on garments. Spots are removed using a hand spot gun or by using a stain
removing machine prior to pressing. Dust and stains can be removed by machine washing. So, many
times finishing department wash garments inside department.
5. Repair work andmending
Defective garments may need to repair for stitching and fabric defects. All repair activities are done
in finishing department itself instead of sending defective garments to stitching department.
6. Ironinggarments:
Garments are ironed using a steam iron. This is done to remove creases in the garment. For knitted
garments measurements are set by steam press. Vacuum pressing tables are used for garment pressing.
7. Folding and tagging:
Pressed garments are folded in a specified dimension. Tags, such as price tags and hang tags are
attached to the garment by means of a Kimble gun or threads.
74. 62
8. Packing garments:
Finally, properly folded garments are packed into poly bags as per customer requirements. Individual
poly bags are then packed into bigger cartons.
9. Preparation of packinglist:
The packing in-charge prepares a packing list for the shipment. After packing is completed for
an order, the finishing department informs the concerned merchant.
10. Internal shipmentaudits
Quality department perform internal shipment audit in the finishing department. This audit is done
prior to final inspection.
11. Documentation andreporting
Like other departments, finishing department maintain production records for pressing, and packing.
Types of packing
There are four (4) types of packing are usually done

6.4 Spotremoving
The General Rules of Spot Removing:
1. The longer a stain remains, the tougher it is toremove.
2. Always treat a stain beforelaundering.
3. Blot gently — never rub; and don't ever blot with hotwater.
6.5 Stain Removal
Stain type Used chemical (commercial name)
1. Oil stain Spot lifter
2. General stain Thinner
3. Termeric stain MRS
4. Ink stain MR
5. Glue stain(Polymer based ) Heat gun
6. Rust stain Markvill
7. Print mark Printvill
6.7 Ironing:
Ironing is the use of a heated tool (an iron) to remove wrinkles from fabric. The heating is
commonly done to a temperature of 180–220 °Celsius, depending on the fabric. Ironing works by
loosening the bonds between the long-chain polymer molecules the fibers of the material. While the
molecules are hot, the fibers are straightened by the weight of the iron, and they hold their new
shape as they cool. Some fabrics, such as cotton, require the addition of water to loosen the
intermolecular bonds.
77. 65
Do not iron
Cool iron (110°)
Medium iron (150°)
Hot iron (200°)

6.8 Trims:
Trims cover all the items used in the garment except the basic fabric. There are hundreds of items
used to manufacture the garments. Proper selection of trims and its quality are very important for
styling; otherwise the garment may be rejected or returned by the customers.
Following is a part of list that covers some names of the items:

86. BGMEA University of Fashion & Technology 74
8.1 QUALITY CONTROL:
Quality control concerned with the evaluation of test data & its application of the textile
process, raw materials, intermediate products & final products.
8.2 QUALITY ASSURANCE:
Quality assurance is defined as all those possible planned & systematic actions
necessary to provide adequate confidence than a product or service will satisfy given
requirements for quality.
8.3 Object of quality control:–
Research/ analysis.
Selection of raw material.
Product testing.
Specification test.
Should be given economic requirements.
Quality assurance & so on.
8.4 Quality Management System:
Quality assurance procedure may be provided by the following two major parts–
8.5 ON LINE QUALITY CONTROL:
On line quality control comprises with the new raw material, process control & finish
fabric inspection.
1. Raw material control: As the quality product depends upon the raw material quality
assurance department must ensure that the best quality of raw material are used in the
production.
The chemical should be with a known concentration & high degree of purity.
The dye & chemical should be compatible with each other.
The fabric must be without faults, with uniform absorbency, & whiteness as per
requirement of the subsequent process.
• Process control: The method chosen for the process must be provided with the
necessary parameters, Temperature, PH, water level, Specific gravity should be
checked at each stage of processes.
87. BGMEA University of Fashion & Technology 75
• Finish Fabric Inspection: To ensure that only acceptable quality fabric is used for
producing garments & proper quantity of shipment is received from the supplier.
POINT CALCULATION SYSTEM:
Defect area Point
1”–3” 1
3”–6” 2
6”–9” 3
9”–above 4
For hole in fabric 4
Calculation of point is done by– Actual grade point = × 100
If point grade is below 40 then the fabric is ok. If the grade point is more than the 40
points then inform it to respective officer.
The fabric is also checking for the shading defect in side by side & length. Any non-
conformities / shading will be notified to the manager using inspected reports. Roll
wise color uniformity card is maintained for identification of shade variations.
The result of fabric inspection shall be recorded in fabric inspection report.
8.6 ON-LINE TEST:

9.1 IMPACT OF INTERNSHIP
Industrial training is an integral part of our education in textile engineering. It helps me
to know about the process performed in an industry. It makes me strong enough to
perform my duties in job properly. It also helps me to develop my skill through different
activities.
In this training at Raihan Apparels Limited I have gained following things:
In Dyeing Lab & QC we have learned about process sequence followed in laboratory
and about lab dip and its development process. How to calculate dyeing recipe. In Pre-
treatment we have learned about functions of different chemicals and their application,
the pre-treatment faults and remedies and the machines used in pre-treatment.
In knitting section I learn about different yarn and different type of knitting fabric as
well as production procedure like as came setting, different machine for different knitted
fabric.
In batching section we have a clear idea about machine used in batching.
In color lab section I learn about recipe prediction and calculation. Development of lab
dip sample etc.
In dyeing floor I have learned about the dyeing methods, have learned about the dyeing
methods, gained knowledge about process sequence. In Finishing I learned about
industrial procedure of different textile finishing. In inspection learned about different
faults and their rectifications. In cutting section I saw about how the fabric is cutting and
different cutting machine uses.
91. BGMEA University of Fashion & Technology 79
In sewing section i learn about how the fabric pieces are join together for different type
of garments. In printing section i learn about different type of printing and their machine.
Chemicals used of printing we also seen.
Beside above this we also gather knowledge different sections. It helped me to become
skilled in conducting different process of textile wet processing. The procedures that an
industry follows from start to end of production. About maintenance system and
techniques followed in an industry. The techniques used to get efficient production.
Experienced about the industrial application of different dyeing processes. Industrial
training helped me to know about the responsibility of a textile engineer in industries. It
also helped me to develop a good communication skill.
93. BGMEA University of Fashion & Technology 81
10.1 RECOMMENDATION
The knitting section should improve and modern machinery should add.
The dyeing floor is watery most of the time: it should be cleaned all the time.
To increase overall efficiency, more skilled labor should be used in a project.
The machine stoppage time should be analyzed and minimized.
The maintenance should be carried out when the machine is out of action
(wherever possible) and routine maintenance should be carried out regularly.
There should be a yarn dyeing project.
Sitting arrangement of production officers should be improved.
95. BGMEA University of Fashion & Technology 83
11.1 CONCLUSION
I tried my best to gather all necessary information. Actually, within this short time it is
quite impossible to achieve the goal of our industrial attachment.
During my training period, i knew that the mill is fulfilling the country’s best export
oriented finished fabric with the help of its modern machineries & good management
system.
Mill is settled with utility to give all convenient supports to the productions for twenty-
four hours. It has self-power generator system to satisfy total power consumptions of the
mill.
I am enough fortunate that i have got an opportunity of having a training in this mill.
During the training period i received co-operation and association from the authority full
& found all man, machines & materials on appreciable working condition. All stuffs &
officers were very sincere & devoted their duties to achieve the company’s goal.
To produce a good quality product, a textile engineer must have a vast knowledge about
the production parameters & how to produce high quality product. Now-a-days Textile
field becomes very competitive & the buyer wants 100% quality product. For this it is
very important to know about the latest technologies in textile sector. In our training
period we have learned many things, different types of machines and their functions,
techniques of productions and management system, the responsibility of different
departments of the factory. So it will be very helpful in our future life.
