Problems solved by technology

[0003] Copolyamide fiber is currently a commonly used flame-retardant fiber in the market. The yarn composed of copolyamide fiber has good wear resistance and excellent flame retardancy, but it still has some shortcomings. Due to the relatively high elongation of copolyamide fiber, In particular, the fiber elongation of the meta-aramid fiber is relatively large, and it is easy to be accidentally elongated during the spinning process, and its spinnability and antistatic properties are not ideal
Copolyamide fibers and other flame-retardant fibers are blended and processed, although the above-mentioned shortcomings are overcome to a certain extent, but the fibers are hard and not soft, and the fabrics made of such fibers are uncomfortable to wear. Poor air permeability, long-term wearing will feel wet, and it is easy to generate static electricity

Abstract

The invention relates to fire-retardant fiber blended yarn, a preparation method of the fire-retardant fiber blended yarn and fabrics of the fire-retardant fiber blended yarn. Double-layer fibers are used in the fire-retardant fiber blended yarn which comprises a surface layer and a core layer, the surface layer is composed of, by weight percentage, 20-30% of phenolic fibers, 20-25% of fire-retardant acrylic fibers, 30-40% of copolyamide fibers, 20-30% of antistatic synthetic fibers in a blending mode, the characteristics of the fibers can be sufficiently utilized, the problem existing in single fibers is solved, the spinnability of the fibers is improved, and a fire-retardant effect is improved. The core layer is composed of, by weight percentage, 10-20% of wool fibers, 30-40% of nylon fibers and 40-50% of polyester fibers, cost is lowered, and the air permeability of the fibers is improved. Fire retardant soaking treatment is conducted on the fibers of the core layer, and the core layer is made to have the fire-retardant capacity. The fire-retardant fiber blended yarn can be applied to clothing, home textiles, sports products, health care products, and fire-proof fabrics.

Description

technical field [0001] The invention relates to the field of flame-retardant fibers, in particular to a flame-retardant fiber blended yarn, a preparation method thereof, and fabrics and fabrics thereof. Background technique [0002] The development of science and technology is a double-edged sword. While bringing convenience and improving the quality of life to human beings, it also has a negative impact on human living and working environments. For example, in some workplaces such as high temperature and electric welding, it has brought potential hazards to the living environment of living and operating personnel. The sparks of electric welding can easily cause damage or burning of workers' clothing, which has brought hidden dangers and damage to the body. Therefore, it is necessary to develop flame-retardant fibers. [0003] Copolyamide fiber is currently a commonly used flame-retardant fiber in the market. The yarn composed of copolyamide fiber has good wear resistance a...
