Preshrinking Why Shipments Get Rejected Over This
Many disputes come down to Preshrinking. Below is what inspectors check and why shipments fail.
The core definition
relaxing fabric before cutting. Working figures for Preshrinking normally sit around below 3% residual shrink in mainstream production. Note AATCC 135 verification on the tech pack so nobody tests against an older revision.
Most common cause of failure
Results usually fall outside below 3% residual shrink because the target was never written into the order. Record elastane content alongside Preshrinking, because blends shift the measured value. A result outside below 3% residual shrink usually points to process drift rather than to the fibre itself.
How it is checked
Inspection and laboratory work both refer to AATCC 135 verification. Keeping reference values for Preshrinking lets suppliers quote without extra sampling rounds. Ask for conditioning details together with AATCC 135 verification, since both affect the reading.
Related faults
it prevents size change after purchase, so related complaints often point back to this single parameter. Working figures for Preshrinking normally sit around below 3% residual shrink in mainstream production. Note AATCC 135 verification 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 Preshrinking, because blends shift the measured value. A result outside below 3% residual shrink usually points to process drift rather than to the fibre itself.
