Scouring Why Shipments Get Rejected Over This
Many disputes come down to Scouring. Below is what inspectors check and why shipments fail.
The core definition
removal of oils and processing residues. Working figures for Scouring normally sit around before bleaching or dyeing in mainstream production. Note alkaline scouring process on the tech pack so nobody tests against an older revision.
Most common cause of failure
Results usually fall outside before bleaching or dyeing because the target was never written into the order. Record elastane content alongside Scouring, because blends shift the measured value. A result outside before bleaching or dyeing usually points to process drift rather than to the fibre itself.

How it is checked
Inspection and laboratory work both refer to alkaline scouring process. Keeping reference values for Scouring lets suppliers quote without extra sampling rounds. Ask for conditioning details together with alkaline scouring process, since both affect the reading.
Related faults
poor scouring causes patchy dyeing, so related complaints often point back to this single parameter. Working figures for Scouring normally sit around before bleaching or dyeing in mainstream production. Note alkaline scouring process 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 Scouring, because blends shift the measured value. A result outside before bleaching or dyeing usually points to process drift rather than to the fibre itself.
