Application
The Velcro Tester is designed to evaluate the adhesion and durability of Velcro (hook-and-loop fasteners) used in a wide range of products such as shoes, garments, bags, and hats. This testing device subjects Velcro specimens to repeated stripping and peeling actions to assess their peeling strength (AS) and shear strength (PA), ensuring they meet the required durability standards. The tester is ideal for manufacturers looking to ensure the long-term performance and quality of Velcro fasteners.
Testing Method
Test Method
To perform the test, a Velcro specimen (measuring 540mm x 20 or 50mm) is placed in the Velcro tester. The sample is subjected to repeated peeling and stripping cycles, simulating the wear and tear Velcro undergoes in real-life applications. After testing, a tensile machine (sold separately) is used to measure the peeling strength and shear strength of the Velcro.
Advantages of Velcro
Velcro, also known as a nylon self-gripping fastener, is widely used in various industries due to its ease of use, strong adhesion, and wash resistance. It is an environmentally friendly alternative to buttons, belts, and other fasteners. The durability and practicality of Velcro make it an essential accessory for many clothing applications and outdoor gear.
Proper Use of Velcro
To maintain Velcro’s effectiveness, it’s important to avoid prolonged soaking in water, prevent exposure to excessive dust, and keep it away from high-temperature objects. Over time, dust and debris may adhere to the Velcro’s adhesive surface, diminishing its performance. Regular cleaning is recommended to maintain its durability.
