Magic tape fatigue testing machine
The Magic Tape Fatigue Testing Machine, also known as a Velcro Fatigue Tester or Hook and Loop Fastener Fatigue Tester, is designed to evaluate the durability of hook-and-loop fasteners through repeated opening and closing cycles. After repeated use, the hook and loop components are brought into contact and rolled together under a specified load to ensure consistent engagement. Their residual peel or shear strength can then be evaluated using the corresponding strength testing method.
The machine features adjustable loading, a digital cycle counter, and a motor-driven roller system. It is suitable for manufacturers and quality control laboratories that need to evaluate the fatigue resistance and performance stability of hook-and-loop fasteners used in footwear, clothing, bags, and other products.
Application
(1) Footwear: Hook-and-loop fasteners used in children's shoes, sports shoes, and other footwear.
(2) Clothing: Fastening tapes used in garments, workwear, and outdoor apparel.
(3) Bags and Luggage: Hook-and-loop closures used in bags, cases, and luggage accessories.
(4) Textile Products: Hook-and-loop tapes used in textile assemblies and household products.
(5) Industrial Fasteners: Touch-and-close fastening materials used in compatible industrial applications.
(6) Quality Control and Research: Comparative evaluation of fastener durability before and after repeated opening and closing.
For tests requiring residual peel or shear strength measurements, the conditioned specimens should be evaluated using a suitable tensile testing method and the corresponding acceptance criteria.
Standards
(1) DIN 3415-1:1990-06 — Textile touch and close fasteners; requirements. This standard specifies requirements for textile hook-and-loop fasteners. Its applicability to the intended test configuration should be confirmed.
(2) SATRA TM123:2018 — Closure strength of touch and close fasteners. This method covers peel and shear strength, including strength changes after repeated opening and closing.
(3) ISO 22776:2004 — Footwear — Test methods for accessories: Touch and close fasteners — Shear strength before and after repeated closing.
(4) GB/T 3903.20-2008 — Footwear — Test methods for accessories: Touch and close fasteners — Peel strength before and after repeated closing.
(5) GB/T 3903.21-2008 — Footwear — Test methods for accessories: Touch and close fasteners — Shear strength before and after repeated closing.
(6) GB/T 23315-2009 — Touch and close fasteners. This is a product standard for hook-and-loop fasteners rather than a standalone fatigue-testing method.
