Glossary term
DWR
Also known as: Durable Water Repellent
A surface finish applied to the face fabric of a garment to cause water to bead up and roll off rather than soak in.
Definition
DWR finishes are typically fluorocarbon-based or, increasingly, PFAS-free alternatives. They reduce the fabric's surface energy so water beads rather than wets.
DWR degrades with abrasion, dirt and wash cycles, and is a known durability compromise in waterproof-breathable garments.
Why it matters to DSEAMS
Seperb Liquiyarn supports DWR and hydrophobic attributes at the yarn level — engineering repellent behaviour into the fibre rather than applying it to the finished garment.
