When the two sides are pressed together, the hooks engage the loops. This creates a bond that is exceptionally strong and allows for repeated use without the products wearing out. Hook and loop fasteners are made out of several different monofilament materials such as nylon, polyester and polypropylene. Monofilament is a single, continuous strand of synthetic fiber (as opposed to woven fibers) used in fishing line, tennis racquets and medical sutures. Nylon is durable, tough and light in weight.
