How is velcro made?

Velcro is made by weaving two different types of nylon or polyester fabrics: one with tiny hooks and the other with loops. The hook side is created by weaving threads into a dense arrangement that forms small hooks, while the loop side consists of softer, fuzzy fibers that catch the hooks. Once the two sides are created, they are coated with a protective layer and cut into strips, ready for use in various applications. The combination of these two elements allows for a secure yet easily separable fastening mechanism.
