Pre-Production Quality Checks
Fabric Inspection
Test fabric weight and thickness using standardized scales. Check fabric color uniformity across the entire bolt. Verify fiber content matches purchase specifications. Test fabric shrinkage by washing samples. Examine for defects like holes, stains, or tears.
Dye Quality Assessment
Verify dye lot numbers match purchase orders. Check color fastness to washing, rubbing, and perspiration. Test color stability in sunlight exposure. Confirm color samples match approved standards exactly.
Thread Quality Analysis
Inspect thread strength and consistency. Verify thread color matches design specifications. Check for thread breakage or weak spots. Test thread durability through mechanical testing.
In-Process Quality Control for Tirupur Garments
Cutting Quality
Inspect cutting precision and accuracy. Check pattern alignment on fabric. Verify symmetry in all garment pieces. Monitor fabric waste and utilization rates.
Sewing Quality
Examine stitch length consistency. Check seam strength through pull tests. Inspect for broken stitches or loose threads. Verify seam alignment and straightness. Test seam allowances match specifications.
Finishing Quality
Inspect hemming for even stitching. Check button and zipper attachment strength. Examine collar and cuff quality. Test label attachment security. Verify seam pressing quality and flatness.
Post-Production Quality Checks
Garment Measurements
Verify length, width, and sleeve measurements. Check sleeve cap height and armhole depth. Test garment symmetry side to side. Use calibrated measuring tools for accuracy.
Color Matching
Compare finished garment colors to approved samples. Check color consistency across all garments in batch. Test color stability after washing and drying. Verify dyeing is uniform without streaks or uneven areas.
Pilling and Durability
Test fabric pilling resistance using standard pilling tests. Check fabric strength and tear resistance. Test for snags and pulls. Verify color fastness after multiple wash cycles.
Button and Zipper Inspection
Test button attachment strength with pull tests. Verify zipper operation smoothness. Check zipper durability through multiple use cycles. Inspect for broken zippers or buttons.
