Velcro

Description

[Velcro USA Inc.] A registered trademark for a reclosable fastener system first patented in 1952 (U.S.) by George de Mestra, a Swiss inventor (patent expired in 1978). 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 two types of hook systems: flexible and molded. The flexible woven 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.
