Problems solved by technology

[0005] At present, people are developing products in the field of UV resistance or flame retardancy, but they are limited to unilaterally modifying fibers for UV resistance or flame retardancy, and cannot solve how to organically combine the two to obtain fibers with a wide range of multifunctional applications.

Abstract

The invention discloses an uvioresistant and flame retardant polyester fiber and a preparing process and an application thereof. The uvioresistant and flame retardant polyester fiber is made of, by weight, 8-15 parts of uvioresistant master batch and 85-92 parts of copolymerization phosphorus flame retardant polyester fiber-forming resins. According to the polyester fiber, the ratio between components is scientific and reasonable, the uvioresistant master batch and the copolymerization phosphorus flame retardant polyester fiber-forming resins are scientifically bonded organically so as to prepare pre-oriented yarns, the pre-oriented yarns are subjected to elasticizing texturing to produce low stretch yarns, and then multifunctional polyester fibers which are resistant to ultraviolet permanently and flame retardant can be obtained, and the polyester fibers are wide in application. The preparing process for the uvioresistant and flame retardant polyester fiber is high in operability, reasonable in technology, high in production efficiency and capable of achieving industrial production.

Description

[0001] technical field [0002] The invention relates to a polyester fiber, in particular to an anti-ultraviolet and flame-retardant polyester fiber, a preparation method and an application thereof. Background technique [0003] As one of the three main fibers in synthetic fibers, polyester fiber is widely used in clothing fabrics and other non-clothing fields because of its excellent physical and chemical properties. It is used as the main textile raw material to weave into various textiles. [0004] With the development of industry, the degree of environmental pollution increases, the emission of halogen-containing compounds such as freon, and the thinness of the atmosphere lead to an increase in the transmittance of ultraviolet rays, so the protection against ultraviolet rays has become a necessity, and anti-ultraviolet fibers are gradually Popular favored. In addition, the fire caused by the burning of textiles has become one of the major disasters in modern life, whic...
