Velcro is a versatile fastening technology that has found widespread use in various applications, from clothing to aerospace. In this lesson, we’ll delve into the history, mechanics, and significance of Velcro.
The Invention and Development of Velcro
Velcro was invented by George de Mestral, a Swiss engineer, in 1941. He was inspired by burdock burrs that stuck to his clothes and his dog’s fur during a walk in the Swiss Alps. The name “Velcro” is derived from the French words “velours” (velvet) and “crochet” (hook).
How Velcro Works
Velcro consists of two components: hook tape and loop tape. The hook tape has tiny, stiff hooks, while the loop tape has softer loops. When pressed together, the hooks engage with the loops, creating a secure yet easily detachable fastening. Velcro fasteners are often used in situations where a temporary or adjustable bond is required.
