194 1 one autumn, after picking in the Swiss Alps, Mistenau found many grass seeds on his trousers and dog hair when he came home. He was curious about this, so he enlarged the grass seeds and found that there were many small hooks on the surface of the grass seeds, which could make the grass seeds stick to clothes and dog hair.
Misnau realized that this natural phenomenon might have practical application value. He began to try to imitate the design of grass seeds, and finally succeeded in inventing a practical closed system, which consists of two parts: a belt with a small hook and a belt with fine fluff. When these two parts are combined together, they can adhere to each other to form a reusable connection mode.
1948, George de Mistnau obtained the invention patent and named it "velcro" (English name of hook and loop). This name is a combination of two French words "velvet" and "crochet", which accurately describes the two components of the shackle.
The invention of hook and loop has been widely welcomed, especially in the design of clothing and other products. Instead of many traditional buttons, zippers and buttons, the connection is more convenient and fast. Nowadays, shackle has become one of the common closed systems in daily life and plays an important role in various applications.
