Stitch Length Why Shipments Get Rejected Over This
Many disputes come down to Stitch Length. Below is what inspectors check and why shipments fail.
The core definition
yarn length consumed per stitch. Working figures for Stitch Length normally sit around 2.6-3.4 mm typical stretch knit in mainstream production. Note machine cam setting on the tech pack so nobody tests against an older revision.
Most common cause of failure
Results usually fall outside 2.6-3.4 mm typical stretch knit because the target was never written into the order. Record elastane content alongside Stitch Length, because blends shift the measured value. A result outside 2.6-3.4 mm typical stretch knit usually points to process drift rather than to the fibre itself.
How it is checked
Inspection and laboratory work both refer to machine cam setting. Keeping reference values for Stitch Length lets suppliers quote without extra sampling rounds. Ask for conditioning details together with machine cam setting, since both affect the reading.
Related faults
small changes alter weight, stretch and recovery, so related complaints often point back to this single parameter. Working figures for Stitch Length normally sit around 2.6-3.4 mm typical stretch knit in mainstream production. Note machine cam setting on the tech pack so nobody tests against an older revision.
Avoiding rejection
Agree targets, tolerances and the method before production, then test per lot rather than per shipment. Record elastane content alongside Stitch Length, because blends shift the measured value. A result outside 2.6-3.4 mm typical stretch knit usually points to process drift rather than to the fibre itself.
