What Is Hook And Loop Made Of?
Most hook and loop fasteners are made out of nylon, but there are several different monofilament materials such as polyester and polypropylene that are also used. Monofilament is a single continuous strand of synthetic fiber (as opposed to woven fibers). Monofilament is used in fishing line, tennis racquets and medical sutures.
Nylon is durable, tough and light in weight. It can withstand high temperature variations but has a low resistance to ultraviolet light. Polyester, on the other hand, is resistant to ultraviolet light but has a lower tolerance to high temperatures. Nylon and polyester are also hydrophobic materials, meaning they do not easily absorb water.
Treated Hook And Loop
Some hook and loop is treated, typically by spraying the material, to add a layer of protection or function. This can include keeping the material from fraying when cut, to more specific purposes like allowing the material to burn slower to meet fire retardant (FR) standards. Another specific example is spraying the hook and loop with silver to give it electric conductivity for use in static or radio environments.How Are Hook And Loop Fasteners Made?
The simple concept of the hook and loop design took a while to perfect before evolving into the technology of today. The hook side is created by weaving nylon under hot, infrared light. The nylon monofilament used in the making of the hooks keeps its shape and is very resilient. After weaving, the loops of nylon get trimmed off to create many hooks that then match up with the loops in the soft side. These hooks need to be cut in just the right place so that they can adhere to the loop side and be fastened and unfastened many times.
Hook and loop fasteners are available in sew on and peel and stick versions as well as many specialized varieties of hooks and loops. This very unique and convenient fastening system is used in a broad range of industries around the world, including aerospace, automotive, medical and military sectors.

Additional FAQs:
Q. What material is VELCRO® made of?
A. VELCRO® is typically made from nylon or polyester. The hook side consists of stiff nylon or polyester hooks, while the loop side is made from softer, flexible nylon loops. These materials are durable, lightweight, and resistant to wear, making them ideal for the fastening system. Some variations of VELCRO® may use different materials, such as polypropylene or other synthetic fibers, depending on the specific application or environment.
Q. How is the VELCRO® manufacturing process different from other fasteners?
A. The VELCRO® manufacturing process differs by using a hook-and-loop system, where hooks grip loops for repeated fastening. Unlike zippers or buttons, it's made by weaving nylon or polyester fibers and heat-treating them. It offers customizable strength, flexibility, and ease of use, without the need for precise alignment.
Q. How is VELCRO® made to ensure durability and longevity in various applications?
A. VELCRO® is made with durable nylon or polyester, woven into strong hooks and loops. The materials are heat-treated to withstand wear, moisture, and environmental factors. Its design allows for repeated fastening and unfastening, ensuring longevity in various applications.
