Velcro is the name given to a fasteners and fasteners system made from two independent pieces of fabric that join together, one composed of small hooks and the other by tiny rings that guarantee the fit.
The word Velcro is actually the brand of this model of fastener, which was invented in 1948 by Swiss engineer Georges de Mestral.
During a walk in the countryside with his dog, de Mestral was intrigued by how the burrs (Arctium) stuck to his clothes and the animal's fur. By examining the burr's structure under a microscope, he discovered that they had small hooks with a great capacity for adherence.
In 1951 the first patent for Velcro appeared, and currently, mainly in Brazil, this word is used to refer to any type of fabric that sticks easily with another.
The word velcro was created from the joining of two French terms: velours ("velvet") and crochet ("hook").
Even though it is a registered trademark, Velcro ended up becoming a generic term used to refer to this type of closure / fastener.
But, it is noteworthy that, for reasons of copyright, no company can use the word Velcro to promote products made with this system.
Velcro is a mechanism used in many things, from clothes, toys, protective equipment and even by astronauts in space.
