TEXTILES AND APPAREL INDUSTRY FASTENING SOLUTIONS

Woven Fastners

The VELCRO® brand woven hook and loop fastener is where it all began. In the early 1940’s, Swiss inventor George de Mestral went on a walk with his dog. Upon his return home, he noticed that his pants and his dog’s fur were covered with cockleburs. His inventor’s curiosity led him to study the burrs under a microscope, where he discovered their natural hook-like shape.

This was to become the basis for a unique, two-sided fastener - one side with stiff “hooks” like the burrs and the other side with the soft “loops” like the fabric of his pants. The result was VELCRO® Brand woven hook and loop fasteners, named for the French words “velour” and “crochet.”
