QUALITY ASSURANCE
Introduction
It is the objective of any manufacturer to offer his customers first quality merchandise. The purpose of the quality control program is to assist manufacturers in meeting their high standards. In addition quality control program can help them in their operations quality control program, spot and reject Defective items and more importantly pinpoint production operations that need special attention thereby reducing the future production failures. This type of quality control provides a basis for management decisions in the plant.
Quality is
Fit for use
Conformance to requirements
When customer is satisfied and encouraged to buy when it is defect free
When it has a long life
When it has good wear ability and wash ability
General quality problem break up:
Sewing : 75% Fabric : 14% Finishing : 10% Others : 1% Total : 100%
Methods of Quality Control:-
1) Testing
2) Inspection

Inspection:
Inspection may be defined as the visual examination in relation to some standards.
Objective of Inspection
The main objectives of inspection are
Detection of defects Correcting the defects or defective
GARMENT SPECIFICATION
Spec sheetA specification sheet, commonly abbreviated to “spec sheet,” is a technical document that sets out the details of how, exactly, a certain product is intended to perform or function. These sorts of sheets are very common in the information industry, particularly as relates to computer and software design, though they are used in any circumstance where something needs to be built or constructed in a precise way. Construction projects, general manufacturing, and some telecommunications work are all places where this sort of document can be found.
Specification sheets provide important details to ensure the correct execution of your patterns into finished garments. Spec sheets help to produce accurate samples, which improves turnaround time and simplifies communication during all stages of manufacturing and quality control.
Spec sheets include detailed technical diagrams, construction notes, finished garment measurements, fabric yields and material and trim details. We can tailor the format and information provided to suit your company’s individual needs.

QUALITY ASPECTS IN DEPARTMENTS
FABRIC AND TRIM STORE
4 POINT SYSTEM
The 4 point system is generally used for fabric inspection. In this system, points are assigned
for every possible defect in the fabric as follows.
Width wise point criteria Penalty points
Upton 3” 1 point
3-6” 2 points
6-9” 3 points
9” 4 points
11
Length wise point criteria Penalty points
Upton 5” 1 point
3-6” 2 points
6-9” 3 points
9” 4 points
Area wise point criteria Penalty points
1X1 cm float 1 point
Upto 1X1 cm hole/stain 2 points
Over 1X1 cm to 2X2 hole/stain 3 points
Over 2X2 cm hole/stain 4 points
Yarn variation/Beam motion/Barre effect Penalty points
Minor 2 points
Major 4 points
• 3 points and 4 points are pointed and are called Cutable defects.
• 1 and 2 point are identified by stickers and panels replaced cutting.
• If defect points/100m3 < 40 then accept the fabric.
• If defect points/100m3 > 40 then reject the fabric.
Major woven defects: slubs, holes, missing yarns, yarn variation, end out, and soiled yarns,
wrong warns.
Major dyeing or printing defects: out of register, dye stops, machine stops, color out, color
smear, or shading.
These defects are marked with colored tape so that they can be easily located.
Others Penalty points

FABRIC TESTING
• Fabric Shrinkage
• Color Fastness or Crocking
• Centre Selvedge
This test is used to check the color variation in the fabric. Full width of the fabric is taken
(length can vary according to requirement say 10”). The Fabric is divided into 6 pieces
and their grain line is marked.
These pieces are then cut and re stitched in a random series. For e.g. 3, 6, 2, 5, 4, 1.
When we arrange these fabric pieces in a series, we can see the shade variation in the
same fabric. Noting of this variation is very important at the time of cutting.
Maximum CS is seen in solid/printed fabrics as compared to stripes and checks.

MARKER MAKING AND LAY PLANNING
MARKER DEFECTS
Some parts of pattern are missing, probably because the marker did not include
the correct number of parts.
Mixed parts, probably because the marker is not correctly labeled, resulting in a
marriage of wrong sized parts. Patterns not facing in correct direction on napped
fabrics.
Patterns not aligned with respect to the fabric grain.
14
Poor line definition (e.g. too thick chalk; indistinctly printed line, perforated lay
not powdered) leading to inaccurate cutting.
Skimpy marking, caused by either the marker did not use the outside edge of the
pattern; or the pattern was moved or swung after partial marking to squeeze the
pattern into a smaller space for economizing the fabric.
The pattern may have worn out edges.
Generous marking, especially in combination with skimpy marking results in
components being sewn together with puckering and pleating.
When the marker is too wide, the garment parts at the edges of the lay get cut
with bits missing.
Not enough knife clearance freedom.
Wrong check matching, i.e. lines across the seam are not matching.
Wrong checks boxing i.e. checks are not showing a full/partial box across the
seam.
Notches and drill marks omitted, indistinct or misplaced.

Spreader should spread rolls according to shade. If two shades must be used in a
spread, tissue paper should be used to separate the rolls.
15
Spreaders should also make sure that fabric defects are cut out of the rolls of
fabric before they are spread.
SPREADING AUDIT
Inaccurate ply count
Wrong color
Wrong marker
End loss exceeds allowance
Inaccurate set up
Improper shading
Wrong cut number
Inaccurate tickets
Four point flaw left in (marked)
Wrinkle
Over Splice
Under Splice
Four point flaw left in (unmarked)
One cutout not utilized in spread remnant
Selvage cutting edge variance >1/2”
FABRIC CUTTING AND BUNDLING
CUTTING AUDIT
• Miscut: Check for miscut or the failure of the Cutter to split the line. Tolerance is
1/16”. Report all defects for miscuts to Cutting Foreman (Supervisor).
• Matching Plies: Check the top ply with the bottom ply to see that they are the same.
Compare both to a hard pattern or paper maker. Tolerance is 1/8”.
• Ragged Cutting: Check for ragged cutting according to the standards of the customer.
It is a judgment defect. It is important on critical parts that if it has to be re-cut then it is a
defect.
• Notches: Check the notch location by placing the pattern over the top ply. Any
critical notch missing needs to be checked 100%. Tolerance is 1/8”.
• 10% of bundles in a cut should be inspected

SEWING AND ASSEMBLY
INSPECTIONS
• Inline inspection: Our assembly line check points ensure 100% checking is done for the
partially stitched garments and only defect free garments are forwarded to the next stage of
garment manufacturing.
• Roaming inspection: Designated checkers randomly check pieces at each operation along
the assembly line.
• Traffic light inspection system: In this system check each operator is given a card for
measuring their quality performance. The quality checker goes to the operator and
randomly checks a few garments. The inspection result is marked red or green on the card
post scrutiny based on rating criteria.
• End of line inspection or table checking: Our checkers scrutinize each completely stitched
garment at the end of the line. This ensures 100% checking is done for all garments
proceeding to the next stage of garment manufacturing.
• Auditing of checked pieces: Our audit procedure is a checkpoint that ensures that only
100% inspected garments are sent for finishing. This audit also ensures that all defective
pieces are removed from the assembly line.
17
COMMON DEFECTS
Sewing Defects: These defects are usually caused by errors arising from wrong
functioning of sewing machines.
o Skipped Stitch
o Staggered Stitch
o Unbalanced Stitch
o Variable Stitch
o Open Stitch
o Needle Mark
Seaming defects: These defects are usually caused by errors arising from the
interaction of the operator and machine in the handling of garment.
FINAL PRESSING AND FINISHING
FINISHING AUDIT
Initial finishing inspection: During initial finishing we ensure that the garment is scrutinized
prior to being sent for pressing.
• Final finishing Inspection: After the garments have been pressed they are again checked
and sent for tagging and packaging.
• Internal final audit: Our quality control team carries out a final audit of all packed
garments. This audit is carried out to guarantee that before handing over shipment, only top
quality garments reach our clients.
Effective quality control at each process ensures that defective garments are removed
before handing to the next step of garment manufacturing. Our checks ensure that at the
end of production the chances of having a defective garment are slim.

CONCLUSION
It is important to maintain a level of quality for every industry or business to get increased sales and better name amongst consumers and fellow companies. Especially for the business engaged in export business has to sustain a high level of quality to ensure better business globally. Companies who are into export business hold the prestige of the country, and due to this generally quality control standards for export are set strictly. It becomes mandatory to have good quality control of their products as export houses earn foreign exchange for the country. In the garment industry quality control is practiced right from the initial stage of sourcing raw materials to the stage of final finished garment. In this industry, product quality is calculated in terms of quality and standard of fibres, fabric construction, yarn, surface designs, colors fastness and the final finished garment products. The quality expectations for export are related to the type of customer segments and the retail outlets.
