The emergence of PU hot melt yarn has given textiles a new look. Its synthesis is a major breakthrough in the chemical fiber industry and a milestone in polymer chemistry. PU hot melt yarn has excellent tensile, impact resistance, wear resistance, chemical corrosion resistance, surface hardness and other functions. It is widely used in the manufacture of industrial ropes, industrial cloth, cables, conveyor belts, tents, fishing nets, etc.
Nylon hot melt yarn has high strength, impact resistance, high temperature resistance, corrosion resistance, moth resistance, acid resistance, alkali resistance, and light resistance (second only to acrylic). The fabric is easy to wash and dry and has good shape retention. This product is mainly used to make decorative fabrics. The gloss of nylon yarn is worse than that of silk, just like a layer of wax. Nylon filament is mainly used to produce silk. It is mainly used in the knitting and silk industries, such as single silk stockings, elastic stockings and other wear-resistant nylon stockings, nylon gauze, mosquito nets, nylon lace, elastic nylon tops, various nylon or woven products, etc.
The main physical and chemical properties of hot melt yarn are shown in the following aspects:
Hygroscopicity and colorability – Nylon is a synthetic fiber with good hygroscopicity. Under normal atmospheric conditions, its moisture regain can reach 4.5%. In addition, nylon has good dyeability and can be used to dye acid dyes, disperse dyes, etc.
Light resistance, heat resistance, etc.: Due to the high sensitivity of polyamide fiber polymer end groups to light and heat, polyamide fiber turns yellow and brittle, so it has poor light resistance and heat resistance and is not suitable for outdoor fabrics. In addition, nylon has good corrosion resistance, is not afraid of mildew, and is not afraid of moths.
High elongation and wear resistance – high strength, high elongation and excellent elasticity. It has good wear resistance and is an ideal material for producing friction products. However, nylon has a small initial modulus, is easily deformed, and the fabric is not stressed.
