Durable Water Repellent (DWR) Why Shipments Get Rejected Over This
Many disputes come down to Durable Water Repellent (DWR). Below is what inspectors check and why shipments fail.
The core definition
finish that makes water bead off. Working figures for Durable Water Repellent (DWR) normally sit around after 20 washes still grade 3+ in mainstream production. Note AATCC 22 after ISO 6330 washing on the tech pack so nobody tests against an older revision.
Most common cause of failure
Results usually fall outside after 20 washes still grade 3+ because the target was never written into the order. Record elastane content alongside Durable Water Repellent (DWR), because blends shift the measured value. A result outside after 20 washes still grade 3+ usually points to process drift rather than to the fibre itself.

How it is checked
Inspection and laboratory work both refer to AATCC 22 after ISO 6330 washing. Keeping reference values for Durable Water Repellent (DWR) lets suppliers quote without extra sampling rounds. Ask for conditioning details together with AATCC 22 after ISO 6330 washing, since both affect the reading.
Related faults
PFAS-free chemistry is now the default requirement, so related complaints often point back to this single parameter. Working figures for Durable Water Repellent (DWR) normally sit around after 20 washes still grade 3+ in mainstream production. Note AATCC 22 after ISO 6330 washing 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 Durable Water Repellent (DWR), because blends shift the measured value. A result outside after 20 washes still grade 3+ usually points to process drift rather than to the fibre itself.
