Air-Jet Textured Yarn Quality Control: The Defects Buyers Reject Most
Quality defects around Air-Jet Textured Yarn cause most claims, and knowing the common ones in advance keeps inspection simple.
Defect one: shade variation
Visible differences within an order remain the top complaint. Checking shade under standard light before cutting avoids most cases. Buyers usually ask for 150-300 denier printed on the technical data sheet before sampling starts. Evidence for cotton-like bulk with filament strength is easier to compare when every supplier quotes against the same method.
Defect two: hand feel drift
Fabric that changes handle between lots usually indicates a finishing bath difference rather than a yarn change. Development lots should be tested next to bulk lots, since results drift between them. Documentation for Air-Jet Textured Yarn normally covers 150-300 denier along with the certificate reference.
Defect three: dimensional instability
Size drifting outside 150-300 denier usually starts at the stenter, where temperature and overfeed were not matched to the construction. For heavyweight fleece and outer, written measurements help avoid disputes once the shipment arrives. Buyers usually ask for 150-300 denier printed on the technical data sheet before sampling starts.
Defect four: surface faults
Barré, snagging and oil spots account for a large share of cutting room waste in heavyweight fleece and outer. Evidence for cotton-like bulk with filament strength is easier to compare when every supplier quotes against the same method. Development lots should be tested next to bulk lots, since results drift between them.
Inspection practice that works
Inspect to an agreed 4-point system, record photographs, and look again after one home wash since several faults only appear then. Documentation for Air-Jet Textured Yarn normally covers 150-300 denier along with the certificate reference. For heavyweight fleece and outer, written measurements help avoid disputes once the shipment arrives.
