Abstract

The invention discloses a method for manufacturing water-resistant Velcro bands. The method comprises the steps of weaving Velcro bands, cleaning, whitening, dehydration, water repellent finishing, baking, resin finishing and drying. In the water-resistant Velcro bands manufactured by the method, hydrophobic polyester PET or PBT is utilized to reduce the water absorption rate of fiber for raw materials; monofilaments are utilized to replace conventional Velcro band multifilaments to reduce the water absorption rate of fiber assembly; a water-repellent film is formed on the outer surfaces of the Velcro bands through water repellent finishing to prevent moisture from entering the surface and inside of fiber; the water repellency and strength of Velcro band ground structure are further enhanced through resin finishing to prevent the tearing or decoherence of the Velcro bands the process of cutting, sewing and using from causing the reduction of water repellency. Through the reinforcement of the manufacturing method, the Velcro bands are excellent in water resistance, and when the Velcro bands are used in water and for cleaning articles, the Velcro bands are free from the reduction of strength and persistent to use, so the method has the advantages of expanding the use of the Velcro bands and increasing the added value of the Velcro bands.

Description

Technical field: [0001] The invention relates to a processing method for a buckle, in particular to a method for manufacturing a water-resistant hook and loop. Background technique: [0002] Existing ordinary nylon hook and loop fasteners, when used for hook and loop fasteners for aquatic products such as diving suits, swimming suits, water sports suits, fishery work clothes, firefighting suits, etc., and hook and loop fasteners for cleaning supplies, because they do not have water resistance, it is easy to cause damage. The phenomenon of reduced strength and shortened service life reduces the added value due to the limited use of the hook and loop fastener. Invention content: [0003] The object of the present invention is to overcome the defects of the prior art, and provide a water-resistant hook and loop fastener and a manufacturing method thereof. [0004] The manufacture method of water-resistant Velcro of the present invention is to weave Velcro first, utilize hydr...
