Description
[Velcro USA Inc.] A registered trademark for a reclosable fastener system developed by George de Mestral, a Swiss inventor, after he closely examined a cocklebur's ability to stick to clothing and fur. Mestral formed Velcro S.A in Switzerland in 1952 and received his first set of patents for Velcro in 1954. Velcro® is a two-component nylon system in which one component has hooks and the other has loops. When pressed together, the Velcro® hooks firmly grasp the loops. The two components may be separated by pulling. Velcro® produces various hook designs in order to provide variations in lifetime vs. strength. For example, for two types of hook systems called flexible and molded. The flexible hooks provide maximum cycle life while the molded hooks provide maximum fastening strength with limited cyclability. Velcro® fasteners work effectively in temperatures ranging from -56C (-70F) to 93C (200F). The fasteners may be attached to substrates by sewing, heat sealing or pressure sensitive adhesives. Factory applied pressure-sensitive adhesives can be acrylic, rubber, or Polyurethane based materials.
