Garments Quality Check Points and their Checking Criteria
Here given section wise quality checkpoint description for your better understanding as mentioned every work of garments quality control department.
Cutting Process Quality Check Point
- Fabric upside down: Make sure the fabric is not upside down.
- Fabric Skewing: A maximum skewing of 2 cm for the chest of 60 cm is acceptable, but not more. This defect can be solved by re-setting of the fabric at the fabric mill.
- Relaxation: Before cutting, knitted, elasticized woven fabrics should be suitably relaxed for around 12~24 hours or more, depending on the type of fabric. Relaxation is mandatory for stretch fabrics.
- The height of cutting pile: The higher the pile on the cutting table, the more chance the cut pieces are unequal in size. This can lead to size specification & fitting problems. Make sure the height is suitable for the type of fabric (usually 2~3 inches and never more than 5 inches).
- Numbering and bundling: Make sure the different parts are properly numbered to avoid shading and that this numbering can be easily removed after sewing is complete.
- Storing: Make sure the different parts are properly stored, for example, rolled, and not folded.
Sewing Process Quality Check Point
- Critical operations: Check all critical operations repeatedly (like the sewing of the neck- seam, armhole, cuff, placket etc.), so the operator gets the clear input of what is required and how to make it correctly before large quantities of garments are finished.
- Attaching label should be correct as per the size of 100% garments
- Checking bonding strength of interlining in the fusing process.
- Seam allowance: check operators repeatedly on this point to make sure they use the correct seam allowance.
- Numbering: Make sure the sewing operatives keep parts with the same number together to avoid shading.
- Confirm Garments styling construction and measurement is correct as per approved sample.
Washing Process Quality Check Point
- Washing method: normal wash, stone wash, sand wash or enzyme wash.
- Bleaching method: stone bleach, garment bleach
- Any special process. E.g. over-dye after the washing process
- The color tone of the blue yarn
- The whiteness of the white yarn
- Resultant color tone: bluer or yellowish
- Rubbing effect: contrast on the blue yarn and white yarn
- Evenness on the blue and white parts
- Record the identification of the sealed sample, quality standards on the final inspection report to ensure QC check the bulk according to the correct standards.
- Tick and sign all quality standards as an indication of proper QC checking.
- QC should not release the shipment if they find the following major faults.
- Color out of the approved shade band
- Fabric flaws and washing marks in excess of 1″ on the garment zone above the knee
- Fabric flaws and washing marks in excess of 3″ on any part of the garment
Finishing Process Quality Check Point
Button Attaching and Button
- Snap button too loose / too strong
- Snap button not closing properly / broken
- Missing poly washer for snap buttons
- Button coming off
- Fabric not strong enough to hold the button
- Mark from molding
- Paint damaged
- Text on button not straight
- Wrong position / not in line with counterpart / incorrect spacing
- Button shank missing when required
- Buttonhole too big or too small
- Buttonhole not clean / badly stitched/ losing shape / stitched with wrong thread quality
- Spare button missing or put in the wrong position
- Shiny marks
- Not pressed or improperly pressed
- Should avoid the press and fold the pigment dyed fabrics before garment washing entirely. It is because it will leave a clearly visible mark on the garment after washing. After sewing, put the garments on a hanger until washing starts.

Without passing final inspection, garments cannot be shipped. A final inspection report is the quality certificate from garments buyer what give a certificate of a factory about their finished product quality that allows or reject to ship garments.
