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.
The name of the shackle is converted from the English name "VELCRO" of the products of Rockfast Company in the United States. In the early 1980s, "VELCRO" products entered China and were distributed by Sanxin Company. Because there is no Chinese name, it is quite inconvenient to communicate, and because the main feature of "VELCRO" is that the fabric with hooks on one side and the fabric with fluff on the other side stick together to produce natural adhesion, which will naturally separate when pulled by hand.
The trade term is called snap. A connecting accessory commonly used in bag clothing. It is divided into male and female sides: one side is soft fiber and the other side is elastic fiber with hook. When the male and female interlock, under the condition of a certain transverse force, the elastic hook straightens, loosens and opens from the pile ring, and then restores the original hook shape, and can be repeatedly opened and closed for 10000 times.
Widely used in garment factories, shoes and hats factories, luggage factories, sofa factories, curtain factories, toy factories, tent factories, glove factories, sports equipment factories, medical equipment factories, electronic plastic factories and various military products, and widely used in all walks of life around the world.
The width of the shackle is between 100mm and 150mm, and the commonly used specifications in the market are 12.5mm, 16mm, 20mm, 25mm, 30mm, 40mm, 50mm, 60mm, 75mm and 80 respectively. Other sizes are generally customized.
1, nylon material
Nylon doesn't burn easily and is very soft. Velcro tape is more suitable for clothing and is a very environmentally friendly material.
2. Polyester materials
Easy to burn, will produce black smoke, accompanied by pungent taste, hard material, rough feel.
3, polyester and nylon mixed materials
It combines all the characteristics of polyester and nylon, is not easy to burn and is very durable. The rubber-backed shackle is made of this material.
4. Nylon Grade A material
Very soft, often used as close-fitting clothes, can also be used on the baby, will not cause skin damage.
5, don't scratch the material
There are mainly hooks and loops that do not scratch fur, but only scratch the surface of fur. Hooks are usually used in conjunction with nylon A-grade materials, mostly for close-fitting clothes.
Adhesive-backed velcro tape is made in the traditional velcro tape (one side of trench coat cuff is hook and the other side is wool, which can be bonded. The back of the shoe tape is processed with a layer of self-adhesive water, which can be attached to plastic surface, hardware surface, wood, electronics and other products at will, with strong adhesion.
