What Is a Hook Fastener?

A hook fastener is a type of closure system that comprises a hook surface and a loop surface. When the two surfaces are pressed together, the hooks grab onto the loops and create a secure closure. Hook fasteners are commonly used in various applications such as clothing, shoes, bags, and accessories.

History of Hook Fasteners

Hook fasteners were invented by a Swiss engineer named George de Mestral in the 1940s. He was inspired by the burdock burrs that stuck to his clothes and his dog's fur during a hunting trip. The burrs had tiny hooks that latched onto anything with a loop, such as clothing or fur.

De Mestral examined the burrs under a microscope and saw that the hooks were made of a tough material that could withstand repeated use. He replicated the hooks using nylon and created a loop surface that could be attached to various materials. He named his invention "Velcro," which is a combination of the French words velours (velvet) and crochet (hook).

Types of Hook Fasteners

1. Sew-On Hook Fasteners

Sew-on hook fasteners are the most common type of hook fasteners. They consist of a strip of hooks and a strip of loops that can be sewn onto fabric or other materials. Sew-on hook fasteners are available in various sizes, shapes, and colors to suit different applications.

2. Adhesive Hook Fasteners

Adhesive hook fasteners have a peel-and-stick adhesive backing that allows them to be attached to surfaces without the need for sewing. They are ideal for temporary applications or for materials that cannot be sewn, such as paper or cardboard.

3. Iron-On Hook Fasteners

Iron-on hook fasteners can be attached to fabric using heat and pressure. They have a heat-activated adhesive that bonds to the fabric when ironed. Iron-on hook fasteners are ideal for clothing or other items that need a durable and permanent closure.

4. Molded Hook Fasteners

Molded hook fasteners are made of a rigid plastic material that is molded into various shapes and sizes. They are commonly used in industrial and automotive applications where heavy-duty closures are required.

5. Back-to-Back Hook Fasteners

Back-to-back hook fasteners consist of two strips of hooks that are attached back-to-back, allowing them to be wrapped around an object and secured in place. They are commonly used in cable management, binding, and bundling applications.

Conclusion

Hook fasteners are a versatile closure system that can be used in various applications. They are easy to use, durable, and come in a range of sizes, shapes, and colors to suit different needs. From sew-on hook fasteners to back-to-back hook fasteners, there is a hook fastener for every application.
