Flex Abrasion and Crease Wear
topic
Flex abrasion tests repeatedly fold fabric over a mandrel under tension while an abradant contacts the fold zone, simulating wear at body crease points such as elbows, knees, and collar folds; cycle count to yarn failure quantifies combined bending fatigue and surface abrasion resistance.
Role
Addresses a distinct failure mode from flat abrasion testing, particularly relevant for workwear, denim, and technical outerwear where crease point wear is the primary durability limitation in real use conditions.
