Hook and Loop 101: Insights from The Pioneers

Everything You need to know about the iconic fastening system from the original creators at Velcro Companies.

What Is a Hook and Loop Fastener?

Hook and loop is an innovative fastening system that can adhere, attach and secure a wide range of applications. The fastener has two sides that link to form a strong bond. One side features tiny hooks, while the other has nylon loops.

This revolutionary technology has spread across various industries thanks to its versatility, adaptability and ease of use. You may know it from sneakers, diaper tabs and blood pressure bands, among many other applications.

Velcro Companies are proud to be the innovators behind the original hook and loop fastener. Although our products consist of hook and loop, not all hook and loop products are from the VELCRO® Brand.

How does hook and loop work?

Hook and loop fasteners work by interlocking tiny hooks on one side with loops on the other side. Inspired by the shape of burdock burrs, the hooks catch onto the loops to form a secure connection. You disengage the fasteners by pulling apart the hooks from the loops.

Initially made from nylon, the product has advanced with technology, allowing us to adapt the fastener according to the application.

Here’s a microscopic look at both sides of our hook and loop tape.

The History of Hook and Loop

Our story began in 1941 when Swiss engineer George de Mestral noticed burrs sticking to his dog’s fur on a walk in the woods. Curious about how they worked, he created a fastening system that copied this natural hook design. He named his invention “Velcro,” a mix of the French words “velours” (velvet) and “crochet” (hook).

De Mestral’s genius idea quickly took off and was adopted by many industries, including aerospace. In fact, NASA utilized it during the Apollo missions.
