The velcro

History

The velcro is one of the inventions that most all the peple used it. The inventor of the velcro was George de Mestral. the idea came to him in 1941 after returning from a hunting trip with his dog in the Alps. He took a close look at the burrs(seeds) that kept sticking to his clothes and his dog's fur. He examinated them under a microscope, and noted their hundreds of'''hooks'' that caught on anything with a loop, such as clothing, animal fur, or hair. He saw the possibility of binding two materials reversibly in a simple fashion, if he could figure out how to duplicate the hooks and loops.

Materials

Velcro is made up of two separate sides.One side is made up of hooks, and the other side is made up of soft loops. Both sides of a strip of velcro are made of nylon, but the process for making the hooks is different from making the loops. The hooks are created under an infrared lamp. The loops are made of matted, nylon  fibers that provide the mates to the hooks.
