Elastic Recovery Why Shipments Get Rejected Over This
Many disputes come down to Elastic Recovery. Below is what inspectors check and why shipments fail.
The core definition
how completely fabric returns after extension. Working figures for Elastic Recovery normally sit around above 90% after cycling in mainstream production. Note ISO 13934-1 recovery loop on the tech pack so nobody tests against an older revision.
Most common cause of failure
Results usually fall outside above 90% after cycling because the target was never written into the order. Record elastane content alongside Elastic Recovery, because blends shift the measured value. A result outside above 90% after cycling usually points to process drift rather than to the fibre itself.
How it is checked
Inspection and laboratory work both refer to ISO 13934-1 recovery loop. Keeping reference values for Elastic Recovery lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ISO 13934-1 recovery loop, since both affect the reading.
Related faults
poor recovery causes bagging at knees and elbows, so related complaints often point back to this single parameter. Working figures for Elastic Recovery normally sit around above 90% after cycling in mainstream production. Note ISO 13934-1 recovery loop 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 Elastic Recovery, because blends shift the measured value. A result outside above 90% after cycling usually points to process drift rather than to the fibre itself.
