VELCRO is a brand name of fabric hook-and-loop fasteners.
VELCRO consists of two layers: a "hook" side, which is a piece of fabric covered with tiny hooks, and a "loop" side, which is covered with even smaller and "hairier" loops.
When the two sides of VELCRO are pressed together, the hooks catch in the loops and hold the pieces together.
When the VELCRO layers are separated, the strips make a characteristic "ripping" sound.
George de Mestral named his invention "VELCRO", which is a portmanteau of the two French words velours, meaning 'velvet', and crochet, or 'hook'.
The term VELCRO is a registered trademark in most countries.
