Hook and loop fasteners consist of two layers of fabric. The first layer is covered with tiny hooks. The second layer is covered with tiny loops. Resins on the hook and loop fastener provide a secure, but easily removable connection. Hook and loop fasteners are commonly known as Velcro®, a registered trademark of Velcro industries. Examples of hook and loop fasteners include standard Velcro hook and loop fasteners, Velcro sew-on hook and loop fasteners, and hook and loop fastener tapes. A Velcro hook and loop fastener consists of small plastic hooks and even smaller plastic loops. A velcro sew-on hook and loop fastener is designed to be sewed onto clothing materials and supplies. A Velcro loop fastener is made of brushed polyamide and contains tiny hairs. Hook and loop fastener tape is made of adhesives that attach quickly to nonporous surfaces such as cabinets and walls. Other hook and loop fasteners are commonly available.
