Hook & ampLOOP, also called adhesive tape or creaking buckle, is a common connecting accessory on clothes, which has two sides of molecules.
One side of the shackle is a small soft fiber, a ring and the other side is a hard hook. Ordinary clothes. Hook is up there.

The shackle was invented by Swiss engineer George de Maesta (1907- 1990). When he came back from hunting, he found grass stuck to his clothes. After observing with a microscope, he found that the fruit of Pennisetum had a hook structure and could be attached to the fabric, so he thought of fixing the wool surface with hooks.
In fact, this structure has long existed in the feathers of birds. The normal feathers of birds are composed of feather shafts and feathers. Feathers are made up of many slender feathers. On both sides of the feather branches are rows of feather branches. Hooks are attached to one side of the feather branches, and rings are attached to the other side, so that adjacent feather branches are hooked to each other to form a solid and elastic feather sheet, thereby moving air and protecting the body.
Feather branches separated by external force can be hooked again by pecking comb of bird beak. When birds peck and comb feathers, they often peck at the fat secreted by fat glands at the tail and smear it to keep the structure and function of feathers intact.
