Longkou is a connecting belt fabric composed of nylon hook belt and nylon velvet belt. The combination of hook belt and velveteen belt can produce greater fastening force and tearing force with a little light pressure, which is widely used in clothing, backpacks, tents, parachutes, curtains, sofa cover and so on. Can be used to replace zippers, snap fasteners, buttons and other connecting materials. Velcro waistband is made of nylon, which is interwoven by plain weave and loop weave. The hook belt is covered with nylon bristles with a diameter of 0.25mm. After heat setting, gluing and hook breaking, a straight hook is obtained. Velvet belt is looped with nylon multifilament, and after heat setting and gluing, an upright, soft and slightly evacuated loop structure is obtained. When the hook belt is combined with the velvet belt, the hard hook can easily hook the soft velvet ring to play a hasp role. The hook breaking process is to cut the bristle ring into hooks; Glue coating is to fix the warp and weft weave points on the base cloth with blank to prevent the hook from falling off and the pile loop from being stretched and elongated when the buckle is used. In addition, there are mushroom-shaped hook belts and knitted velvet belts, which have higher fastening strength and tearing strength, but suede is easy to be damaged, so they are only used in application scenarios where tearing is not frequent.
