Introduction
4. 4
If the theoretical knowledge is a glass of water then the practical knowledge would be
drinking of the water. It is always very easy to make a man understand about a firebox by
showing and lighting practically rather than describing theoretically who has not ever seen a
firebox. So, for any technical education the practical experience is the most important as well
as the theoretical knowledge.
As we are studying in a technical line, it is always important for us to gather the practical
knowledge. Through our study life the only biggest chance for us to combine the theoretical
knowledge with the practical knowledge is the “Industrial Attachment period” that comes
only once in the education life. So we can easily realize the importance of Industrial
Attachment. And in addition the knowledge we gathered from the industrial training
reflects in the report of industrial attachment note book.
So industrial attachment is the process where the trainee can blend his theoretical
knowledge with practical knowledge increasing his/ her ability of work, skillness,
performance and attitude and so on. It also provides sufficient knowledge about
production management, productivity evaluation, work study & efficiency, industrial
management, production planning and control, production cost analysis, inventory
management, utility, maintenance and so on. Industrial attachment makes us reliable to be
accustomed with the industrial atmosphere and also improve courage and inspiration to take
self-responsibility.
As Industrial training is an integral part of the study for the students of Textile Technology,
so after the final exam of 4th
year 2nd
semester, I have taken this training at “NIAGARA
Textiles Limited”, a 100% export oriented apparel manufacturing industry. I tried my best to
prepare this note book applying my best efforts. I tried to gather all the necessary information
to make it a valuable for me as well as for everyone. I think it will help me a lot in future in
my practical life.
Place:
I have performed our industrial training at “NIAGARA Textiles Limited” which is located at
Chandra circle, Union-Atabaha, Kaliakair, Gazipur, Bangladesh. This is a 100% export
oriented knit garments factory. It consists of knitting, knit dyeing, finishing & knit garments.

Total duration of training period was from 15th
October 2012 to 15th

2.7 Description of Production Process:
In every mill there maintains a sequence in production processing. It is also followed
in this mill where we were in industrial attachment. The process sequences are in list
below:
1. Firstly knitting manager gets a production shit from the merchandiser as according as
consumer requirements then he informs or orders production officer about it.
2. Production officer informs technical in charge & knows about machine in which the
production will be running.
3. Technical in charge calls for leader of mechanical fitter troops, they two take decision
about machine for production considering machine condition, production capacity,
maintenance complexity etc.
4. Production officer with experienced mechanical fitter adjusts required stitch length &
grey GSM for required final GSM.
5. Supervisor checks daily production regularity & make operator conscious about
finishing tin due time.
6. Operators operate machine in high attention as if there were no faults in the fabrics. If
he thinks or sure about any fabrics faults then he calls for the mechanical fitters in
duty. Mechanical fitter then fixes it if he can or he informs technical in charge. Then
he comes in spot.
7. After required production & final inspection in 4- point system, they sent in dyeing
section.

3.1 Knitting Fabric Inspection & Grading Based on the Forty points System:
The inspection and grading of fabric quality is one of the important functions of Quality
Control in the grey finished state, the grading of fabric is a difficult task, taking two primary
considerations: as the frequency of effects and the seriousness of defects.
The grading has two primary functions: first, to classify the fabrics according to standard
qualities based on the end-use and customer demands and second, to supply information as to
the qualities actually being produced.
The Knitting fabric can be classified into three levels of quality, each one have a number of
points for defects as follows.
The First quality level 40 points per 100 Linear Yards
The second quality level (40-80) points per Linear Yards
The third quality level 80 points or more per 100 Linear Yards
3.2 General Instruction for the final inspection:
33. 33
All pieces will be graded on the base of 40 points per 100 linear yards Mapping will be done
on each piece to insure proper grading. Do not count more than 4 points per one yard.
a) All effects must be recorded and marked in final inspection and an accurate account
of points made to insure proper grading.
b) All fabric must meet specifications
c) At the end of each piece of fabric, the inspector will add up total points and decide
whether the piece can be shipped as first quality.
d) The quality control supervisor must approve the grading of all quality levels and
check the lower quality.
e) Major or unsightly defects in the first and last yard of a roll of piece will be cut. All
defects of one yard length or more will be cut out of the price. Defects within the first
2 inches or the last 2 inches of a piece will not be cut out or counted in the grading.
f) Open defects on the back of fabric such as drops, runs and hanging picks are to be
included in the grading of fabric.
g) Pieces can be connected together, once each piece must be the same shade.
h) All defects such as runs that extend more than a yard in length will be cut out.
i) Defects within one inch of the fabric edge will not be counted except on tubular
fabrics. All defects will be counted in tubular goods.
3.3 Proper Batching Criteria:
To use maximum capacity of existing dyeing m/c
To minimize the washing time or preparation time & m/c stoppage time.
To keep the no. of batch as less as possible for same shade.
To use a particular m/c for dyeing same shade.

2) Offline quality control
7.2.1Online Quality Control:
Online quality control comprises with the
1) Raw material control,
2) Process control
3) Finish fabric inspection.
7.2.1.1. Raw material control:
As the quality product depends upon the raw material quality, quality assurance
department must ensure the best qualities of raw material (with economical
consideration) are used in production.
The chemical should be with a known concentration and high degree of purity.
The dyes and chemical should be compatible with each other.
The fabric must be without faults, with proper absorbency, whiteness as per
requirement of the subsequent process.
7.2.1.2. Process control:
The method chosen for process must be provided with necessary parameters.
Temperature, pH, water level specific gravity should be checked at each stage of
process.
During dyeing, samples are taken and shade match with lab dip and when match,
allow for bath drop.
If not properly match addition or topping is done until required shade come.
After neutralization sample is collected and match with lab dip.
67. 67
Sample is collected after fixation and matched.
Last of all after softening sample is collected and match with lab dip.
Each batch should be matched with other batch.
During finishing, temperature, speed, padder pressure, overfeed should be
controlled as per requirement.
GSM, width, Spirality, shrinkage (both length & width) should be maintaining as
per buyer requirement.
7.2.1.3. Finish fabric inspection:

8.1SAMPLE SECTION
INTRODUCTION
Sampling is the process by which a small number of garments are made so as to match the
buyer requirement and to get approval from the buyer so as to start off the production. It also
contributes in the domain of product development which helps to present the quality and
capability of service to the buyer. This department executes as per the specifications of
buyer’s order and ensures any correction or alteration before starting bulk production as per
buyer purchase order.
8.1.1Flow process chart for sampling:
Receives the technical package from
merchandising department consisting of fabric
swatches, patterning, cutting and stitching
details.
Pattern master develops the pattern
Pattern is digitized and grading done
with the help of CAD & pattern master
Fabric consumption is calculated and
Mini marker is developed
Cut the fabric after approval from
In- house QA and Buyer’s QA
Stitches the required no. of samples
Sending Samples for Further Processing
71. 71
8.1.2 Various samples which are being developed at different stages are being
mentioned below:-
A) Proto Sample
B) Fit Sample
C) Sales Sample
D) Pre Production Sample / Top of Production Sample
E) Size Set Sample.
Proto Sample :
Proto sample is the rough interpretation of the enquiry done to acquaint the tailors with the
style. It is usually done on the substitute fabrics, and using accessories, what is available and
then checked on the dress form. The quality inspectors from the respective buying houses or
the buyer checks the sample, makes the necessary changes pertaining to the fit, the drape, the
style details etc. Once this stage is completed, it’s time to move on to the next stage.
Fit Sample:
The fit of the garment assumes the pivotal importance in this sample. Usually done with the
substitute/actual fabrics and substitute trims and accessories. It is sent directly to the buyer
for necessary alterations to be made. Depending upon the changes or the comments of the
buyer, the revised fit samples are made till the final approval is obtained.
Sales Sample:
The sales sample is done when the buyer requests for a certain no. of pieces for the promotion
of the product yet to come. It gives the buyer certain types of feedback about his product and
leaves him better equipped to decide on the production quantity. It usually consists of 6 to 7
pieces in each size and color.
Pre production sample:
It is done on the actual fabric using the actual trims and the fit has to be perfect. It is simply a
prelude to the actual production.
Size Set Sample:
It is done according to the buyer’s request. It is almost equivalent of the pre production
sample except that it was done in all the sizes or in the jumping sizes s per the buyer’s
request. The samples were made in the base size in 3-4 copies- Buyer, Factory reference,
Delhi Buying House( Corporate Office) and Bangalore Buying Office. The sampling process
varies from buyer to buyer.

8.2CUTTING DEPARTMENT:
INTRODUCTION
Cutting is one of the important department of the manufacturing unit. The first stage in the
manufacture of the garments is the cutting of the materials into the necessary patterns shapes.
These are then joined together by means of seams to create three-dimensional garments.
Where large quantities of a garment style must be cut, a lay is created which consist of many
plies of fabric spread one above the other. From this, all the garment pieces for all the sizes
that have been planned for that lay are cut. The pattern shapes for these garments maybe
drawn on a paper marker placed on top of the lay, or information as to their shape and
position maybe held within a computer, to be plotted similarly on the paper marker or used to
drive an automatic cutter.
8.2.1 Object of Cutting
The object of cutting is to separate fabric parts from the spread of lay according to the
dimension of the marker for the purpose of garments making according to the pattern pieces.
8.2.2 Requirements of Fabric Cutting
The objective of cutting is to separate fabric parts as replicas of the pieces in the marker plan.
In achieving this objective, certain requirements must be fulfilled.
Precision of cut.
Clean edges.
Unscathed, infused edges.
Support of the lay.
Consistent cutting.

8.2.4 Notes:
After merchandizing department informs about all the shipping date to cutting section, the
cutting section makes a plan about their working schedule and make a list of the fabrics
which have to be cut.
8.2.5 Computerized marker making:
There are two systems for marker making
1. Digitizing system.
2. Automatic system.
8.2.5.1 Factors related to marker efficiency:
Marker planer
Size of garments
Marker length
Pattern engineering
Fabric Characteristics
Marker making method
Marker width.
Style of garments.
8.2.5.2 Marker efficiency: The marker planner measures his success by the efficiency of the
marker plan. The following formula is used to measure the efficiency:
8.2.5.3 Minimization of fabric wastage outside the marker:
There are four points for the fabric minimization outside the marker
1. Ends of ply losses.
2. Loss of fabric in roll.
3. Selvedge loss.
4. Purchase loss.
76. 76
8.2.5.4 Marker ratio:
According to the types of fabric, types of sizes, number of pieces which have to be made, a
marker ratio is decided. If there are some different sizes such as size : 6,8,10,12,16,18 which
have to be made for an order and if the marker ratio is 2,2,2,2,2,2; then it means that two
pieces of each size has to be made from each lay of fabric.
8.2.5.5 Marking paper:
When the sample section delivers the pattern, the design is made on a marking paper. The
design is mainly according to the marker ratio. The pattern of certain design is first put on the
marking paper and then the design is drawn.
8.2.6 Quality check:
After all the parts are finished from cutting then a quality check is made for every piece or
part. If any part is found defected then it is first seen whether the defect can be repaired by
cutting. If it cannot be repaired then the part is rejected.
8.2.7 Exceptional cases:
There are some cases for which some exceptional or extra actions have to be made.
One of the exceptional cases is for the fabric which has to be washed before the
cutting is done. Those fabrics are first arranged and cut according to the length of the
marker. Then they are sent for washing. After the return of the fabrics from washing
the usual cutting process goes on.
Another exceptional case is the fabric of stripe type. Instead of making or spreading
of long lay, lays are arranged in a small length in order to matching the stripes with
one another.. After cutting, each piece is checked whether the stripe so matched
according to the required design. If not matched, another worker cuts the stripe with a
scissor to make the matching. This process continues for each piece of the stripe
fabric. Then the usual numbering, bundling and quality checking continues. The
cutting process or checking for the stripe normally takes longer time than any other
types of fabric as here the stripes needs to be matched and that’s why each and every
part has to be checked.
8.2.8 Fabric Spreading
Spreading means the smooth laying out of the fabric in superimposed layer of specified
length. The cutting marker is laid on the top most layers. The maximum width of the cutting
marker is constrained by the usable width of the fabric.
77. 77
8.2.9 Objects of Fabric Spreading:
The objects of fabric spreading are
To place the number of plies of fabric to the length of the marker plan
correctly aligned as to length and width, without tension.
To cut garments in bulk and saving in fabric through the use of multi garments
marker plans and the saving in putting time per garment that result from
cutting many plies at a time.
To make every ply plain and flat.
To save the time by cutting many layers of fabric at a time.
8.2.9.1 Types of Fabric Lay:
Spreading means the smooth laying of the fabric in
superimposed layer (plies) of specified length and
after spreading the shape of fabric plies is called
fabric lay. Fabric lay may be of different types.
According to the direction of fabric spreading,
fabric lay is of three types.
Fabric spreading from right to left.
Face to face fabric spreading and
Zigzag lay.
In Niagara Textile Limited fabric lay is found by fabric spreading from right to left Fabric
spreading.

8.7 Sewing Problem:
Sewing defect can be classified in three different groups:
1. Problems Of Stitching Formation.
Slipped stitch:
Stitches in the seam are present in a regular wise. If the interloping or interlacing between top
& bottom thread of stitch is not take place or mossed is known as slipped stitch or skipped
stitch. This is more harmful in case of chain stitch than lock stitch. The following are the
causes and remedies of slipped stitch formation given by a table.
No Cause Remedies
01 If hook or looper & needle are
not inserted in loop of thread
in time.
Examine the setting and timing between needle and hook or
looped.
Placing of needle properly.
More secured needle should be used.
02 Irregular thread tension on
upper or lower loop.
The tension of thread should again be adjusted.
03 Due to needle deflection. Needle to be changed.
04 If needle thread loop size is
too small.
Needle size & thread size must be adjusted.
05 When flagging of fabrics
during sewing is happened.
The pressure of pressure foot must be adjusted accurately.
The hole of throat plate & needle size must be adjusted.
Staggered stitch:
If the stitches produced by needle are not parallel or become curvy to sewing line is known as
staggered stitch. The following are the causes and remedies of staggered stitch formation
given by a table:
No. Causes Remedies
01 Needle deflection Increases the needle size.
Tapered needle should be used.
02 Due to wrong or blunt needle point. Needle to be changed
03 Wrong adjustment of needle & thread
size.
Needle size and thread size should be changed.
04 Defected motion of feed dog. Motion of feed dog to be adjusted.
05 If fabrics are not controlled properly in
the feed mechanism.
The pressure of pressure foot must be adjusted accurately.
Feed mechanism to be changed.
93. 93
Unbalanced Stitch:
This type of defect is found in lock stitch machine. If the interlacement of thread are not
taken place in the middle (i.e. if the interlacement is taken place in the upper or lower
position from the middle) of two layers of fabrics then it is known as Unbalanced stitch. The
following are the causes and remedies of unbalanced stitch formation given by a table:
No. Causes Remedies
01 Wrong tension of sewing thread Setting of proper tension to the sewing threads.
Proper care to the twisting of thread during sewing.
02 Used wrong thread path. Use of right thread path.
03 Wrong adjustment of needle
thread path.
Use of right thread path.
04 Snagging of needle with bobbin
case & positioning finger.
Bobbin case to be smooth.
The positioning finger to be set again.
05 If the threads are not lubricated. Better qualities threads must be used.
Table unbalanced stitch
Frequent thread Breakage:
This is the breakage of thread again and again during sewing. And
also, there needs more time and which is harmful for production.
Especially when there needs to open out of sewing to solve the
problem. The following are the causes and remedies of frequent
thread breakage formation given by a table.
No Causes Remedies
01 Wrong winding of threads on to the
bobbin.
Proper winding of threads on to the bobbin.
Pre-wound bobbin may be used.
02 More tension to the bobbin threads or
more rotating of bobbin.
The tension must be adjusted to the bobbin
threads.
Use of washer to prevent the more rotating of
bobbin.
03 If the edges bobbin case, lopper eye
and so on are more sharpened.
The edges to be smooth.
04 Wrong fitting of bobbin case. Examine the size and type of bobbin.
Examine the damaging of bobbin case.
Problems of puckers:
Figure Thread Breakage
94. 94
Unwanted waviness of the fabric along the seam line is called seam pucker. This may be
apparent immediately after sewing or it may develop in later in use. Most of the times,
sewing threads are referred as the responsible for seam pucker. But without sewing threads,
there are so many reasons for occurring seam pucker. Such as fabric structure, seam structure,
needle size, feeding problem, uneven thread tension and so on. This can be seen after sewing
and sometimes after washing of garments. There is a great possibility of seeing seam pucker
in case of more piles of fabrics sewing together. The following are the main reason of
occurring seam pucker.
1. Variable or uneven stretch on fabric piles:
●There is a great possibility of seeing seam
pucker in case of more piled of fabrics sewing
together.
● Due to variable stretch on fabric piles they
will not feed equally to sewing m/c & create
seam pucker.
● this type of pucker is seen for the limitation
of feed mechanism.
2. Fabric dimensional instability:
●If the shrinkage of sewn fabric piles are not same or equal than seam pucker will
create after washing.
●To avoid this. It must be know the shrinkage property of different types of fabrics
before sewing.
●If the shrinkage percentage of area of two pieces fabrics is more than 2, then seam
pucker will occur after sewing the fabrics together.
3. Sewing threads shrinkage:
●Due to variable shrinkage percentage of sewing thread & fabric, seam pucker will
create after washing or ironing.
●To protect this. It must know about the shrinkage percentage of fabric & thread
before selection to sew.
●There is less possibility of occurring seam pucker when sewing is done by synthetic
threads due to less shrinkage percentage of them.
Remarks:
Sewing section is the important section of garments. There are many processes in this section
for making garments. This section needs skilful operator otherwise garments to be fault.

INTRODUCTION
Finishing is the last stage of garment production where garment gets its final look. In this
department each garment undergoes different finishing processes. It undergoes for quality
check for several number of time which sets the garment free from defects. Buyer
specifications and instructions are strictly maintained. Our finishing section is equipped with
modern pressing machines & trained workers. Like other operations, quality of garments is
strictly being controlled here to secure acceptable quality level. Following are the different
finishing processes-

section
The clothes are ironed
A quality check is done to
see if there is any fault in
ironing or in fabric.
Cloths are folded or attached to hanger as per the requirement of
buyer.
Folded parts are packed into poly bag
Folded parts are assorted and kept
in cartons with H-tag as per the
requirement of buyer.
When the fault is in
ironing it is sent for

8.8.2 Ironing:
This is a finishing process done by subjecting a cloth to heat & pressure with or without
steam to remove unintended creases and to impart a flat appearance to the or garments. Also,
pressing is done to introduce creases in the garments, in garments industries, pressing is
called Ironing.
8.8.3Pressing:
Pressing is the process to remove unwanted crease and crinkles from the fabric to give it
smoothness, lustrous and fine appearance. Pressing is a finishing process which is done to
garments by heat and pressure. It is also called ironing in garments factory.
Categories of pressing:
No pressing: Here pressing is not required, e.g. knitted garments such as under
garments, briefs etc.
Minimum pressing: Only heat is applied to garments, such as sweater, T-shirt etc.
Under pressing: Before sewing some parts of garments are pressed for its proper
finishing, such as pants, coats/blazer etc.
Final pressing: After completing the garments final pressing is done then it is packed
to a poly bag for shipment.
Permanent pressing: Many fabric effects are made by heavy pressing; this is known as
permanent pressing, e.g. pleat of shirt, dirt of pant, lapel of coat etc.
8.8.3.1 Objects of Ironing/ Pressing:
1. Remove of unwanted creases and crinkles.
2. To apply creases where necessary.
3. Shaping.
4. Under pressing.

8.7 Garments Defect:
Garment defects can be separated into three categories:
1. Fabric defects:
These are defects that are found in the fabric; mostly these are not caused by the sewing lines.
E.g. running shade, selvedge-to-selvedge shade, holes, staining mark, missing yarn, foreign
yarn, slub, hairiness etc.
2. Workmanship and handling defects:
These are defects that are directly caused by production section, this would include both the
cutting and sewing section. Buyer’s approved samples must be referred to maintain perfect
workmanship.
Workmanship & handling defects are given below;
I. Cutting defects.
II. Pattern defects.
a. Sewing defects:
1. Seam puckering.
2. Broken seam/ open seam.
3. Broken stitch.
4. Slipped stitch.
5. Wavy/ staggered stitch.
6. Uncut/ loose thread.
III. Ironing fault:
a. Look crinkle (if poor ironing)
b. Look shiny (if too much ironing)
IV. Finishing fault:
a. Misplacement of label, hangtag, stitches etc.
b. Misaligned button, unfinished button whole, distance fault of button.
c. Wrong folding.
Note: Workmanship means all the details such as measurement, outlook, ways of attaching
trims, packing etc.
3. Trims, accessories and embellishment defects:
These defects include color, size and placement of trims such as labels, sewing thread, screen
print, embroidery designs, zipper, hangtag, lining, button and any kind of trims.
Defects are also classified (as per extent of defect) into Critical, Major and Minor defects.
101. 101
1. Critical defects are defects that are not allowed to be shipped and are the most serious
of defects (0%).
2. Major defects are serious defects that are not allowed over a certain percentage (3%)
depending on buyer’s requirements.
3. Minor defects are serious defects that are not allowed over a certain percentage (5%)
depending on buyer’s requirements.
Remarks:
The term garments finishing mainly applies to pressing, folding and packing of garments.
After compacting pressing, the garments have to be folded. Garments are folded according to
the direction of buyer’s requirements or in standard area. So finishing department is
important of garments.

This is the most important document sent by the buyer to a merchandiser to start the
merchandising activities.
The technical term of Inquiry Sheet is Product Specification Sheet
(P, S, S,). But some buyer and some manufacturer also use the term of Tech-Pack or Style-
Pack.
The buyer specifies all the necessary points of a particular garment What they want to
purchase-
The merchandiser has to study the P, S.S. very well for farther Activities. He must reply
within 24 hours.

9.8 SWATCH CARD:
What is Swatch Card?
When all the items (fabric and accessories) needed to manufacture a particular style of
garment are attached on a board as a sample by using both side adhesive tapes, it is called
Swatch Card.
Separate swatch card is prepared for different style of garment.
The objective of making 'Swatch Card1
is to assess the quality for production
The items attached in a swatch card are -
Fabric - separately for each different color.
Thread - for different count and type
Button - for different Ligne Number
Label - for different types (main, size & care label etc) and for Différent size (2T,
3T etc).
Price tag
Poly bag
ETC
Swatch Card has to made a few for each separate department, for example -
For Production Manager
For Quality Manager
For Store Office
For Buying house / Buyers representative
For Merchandiser own self
And for each production unit.
9.9 Importance of Swatch Card:
For a merchandiser this is very important for continuing his job.
Without this he cannot move his arena-
It is chat where all materials and accessories are present with their color combination. For
this, it is much more important to lake approval from the buyer as well as to give the
appropriate instructions to the supplier to supply the necessary and appropriate goods.

9.10 How can we get Fabric Consumption & Fabrics Price?
Say: ** Body Length = 85, Chest Width = 52, Sleeve Length = 44 & G.S.M = 240
Fabric Description: 100 % Cotton S/J
Fabric Need = [(85+5
+44+5
) 52+5
] 2 12 240/10000000+10%
= [(90+49) 57] 2 12 240/10000000+10%
= (13957) 2 12 240/10000000+10%
= 7923 12 240/10000000+10%
= 45636480/10000000 + 10%
= 4.563648 +10%
= 4.563648 + .4563
= 5.02 Kgs Fabrics
Say Per Kgs Price: US$ 6.00/Kgs
8.30 Fabrics Price:
Total Fabric Need 5.00 Kg $ 6.00 = $ 30.00
Trim/ Accessories (Minimum Charge) = $ 2.50
Cutting & Making Charge (C.M) = $ 5.00
Printing Charge (If any) = $ 0.00
Embroidery Charge (If any) = $ 0.00
Buying Commission (If necessary) 5% = $ 1.97
= $ 39.47/12

10.0 Physical Tests:
1. Fabric weight (GSM)
2. Smoothness & appearance
3. Color fastness to rubbing
4. Color fastness to light
5. Dimensional Stability
6. Color fastness to wash
1. Fabric weight (GSM):
Fabric is cut by GSM cutter and its weight is measured by electric balance. Then the
result is multiplied by 100 to get the actual result.
2. Smoothness & appearance:
Fabric smoothness & appearance is measured by hand feel.
3. Color fastness to rubbing:
Rubbing time : 10 times
Sample size : 14×5cm

Process:
At first two fabric is cut as per above given dimension.
Then it is sewn in 4 sides.
Then area is req. marked inside the total area.
Then the sample fabric is taken out and washed & dried as per following:
Then measurement is taken again to find out shrinkage%.
112. 112
After washing
Before washing
Shrinkage%= {(before length- after length)/before length} *100 %
Here A = Length measurement before wash
B = Spiraled length.
By this test spirality can also be measured by the following formula,
Spirality % = (B÷A) × 100 %
6. Color fastness to Wash:
