Velcro Fatigue Tester is used to determine the anti-fatigue performance of touch and close fasteners by measuring the test sample’s peel strength or shear strength after being repeatedly opened and closed under controlled conditions.
Velcro tape is also called the hook-and-hoop fastener, which consists of 2 fabric strips which are attached to the opposing surface to be fastened. One strip has tiny hooks, and the other one has smaller loops. When the two are placed together, the hooks catch in the loops, and the two strips fasten temporarily. When pulling or peeling either one component, the strips produce an unusual “ripping” sound. It is widely applied to shoes, apparel, textiles, etc.
