Velcro straps, also known as bonded fabrics manufacturers buckle-free straps, adhesive tapes, are very convenient clothing accessories that can be widely used as clothing, gloves, tents, seats, bags, shoes, hats, luggage, school bags, backpacks, safety Coupling materials for devices, leather goods, drapery curtains, cloth coverings, sporting goods, medical appliances, etc. The invention of Velcro has been in existence for more than 50 years. It was invented by Swiss engineer De Mestral.
It is said that he loves outings and hunting. When he comes back from the suburbs, he often finds that there are some needles on his clothes. It is very troublesome to remove the seeds of these needles. The next seed was placed under a magnifying glass and observed carefully. It was found that the mane on the seed had small hooks, and it was these small hooks that caught the yarn on the clothes. From this he suddenly wondered, if these similar small hooks can be produced on the belt, can it also make the belt overlap each other instead of buttons and zippers?
Inspired by the seeds of the Bidens bipinnata, after 8 years of careful research, he finally designed the shaped product. This is the origin of the Velcro strap. Although the invention of the zipper makes dressing more convenient, quick and sensational in the clothing industry, the invention of the buckle is even better. Secondly, the principle of the nylon tower buckle belt is very simple. It is a textile fabric made of nylon yarn. One kind of woven surface is woven with many loops and the other is woven with many uniform small hooks.
After the two straps are aligned and gently squeezed, the loops are hooked and can only be torn apart when pulled slightly from the head end of the buckle. Therefore, it can play a coupling role to replace buttons and snap , Zipper and other connecting materials are characterized by being very convenient to use, time-saving and fast, and soft on the sewing parts. Nylon buckle tape is made of nylon yarn and is composed of twisted warp and loop forming structure. The hook surface band is made of nylon monofilament with a diameter of the loop. After heat setting, glue coating, broken hook treatment, etc., a hook that is stiff, upright and not easily deformed is obtained. The loop surface band is made of nylon multifilaments, which is upright after heat setting and gumming treatment. It is dense, soft and slightly evacuated. Velcro strap with flat surface and other colors.
