Glossary term

UV protection

Also known as: UPF

A textile's ability to block ultraviolet radiation — a performance attribute increasingly expected of technical apparel.

Definition

UPF (Ultraviolet Protection Factor) quantifies how much UV a garment blocks.

UV behaviour can be delivered by fibre chemistry, weave density or treated finishes.

Why it matters to DSEAMS

Seperb Liquiyarn supports UV protection attributes directly at the yarn level, integrated into the knit's structure.
