How it is made: Velcro
The Velcro was invented by the Swiss inventor Georges de Mestral. He borrowed the idea from the flowers of the burdock: the main thing is to make more hooks that catch on any fleecy surface. The more hooks per square centimeter, the better: one clue is almost nothing, and a lot is already a reliable grip. the first samples were cotton, then nylon went into business, and by the mid-fifties de Mestral had the technology for industrial production of Velcro ready.
To make a lot of tiny hooks, loops are pulled from a heated nylon web, and then they are cut with a saw with very small cloves.
