Durable Water Repellent (DWR) Specification Targets for Buyers
Setting Durable Water Repellent (DWR) correctly on a tech pack prevents most later disputes. Targets belong on the page before the first fabric sample.
Where to write it
Place Durable Water Repellent (DWR) next to composition and weight so all three are quoted as one package. 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.
Reference level
Typical activewear expectation: after 20 washes still grade 3+. 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.
Tolerances that work
Allow a small tolerance rather than a fixed number, since normal process variation exists in every lot. 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.
Verification method
Confirm with AATCC 22 after ISO 6330 washing and keep the report against the bulk record. 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.
Commercial note
Tightening beyond practical need raises cost without improving garment life, so set the tightest target only where it protects the customer. 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.
