High-strength terylene flame-retarding composite yarn and preparation method of same

Abstract

The present invention disclosed a high -strength polyester flame -retardant composite wire and its preparation process, including the body, including the body and the outer core, and the outer surface of the body is painted from the inside to the outside.The base composite coating, which is composed of silver antibacterial mother grains, anti -ultraviolet maternal particles, and co -concentrated phosphorus -based flame retardant polyester resin. The percentage of the ingredients is 3 % to 10 % of the silver antibacterial mother particles.The polyester fiber provided by the present invention is scientific and reasonable in each group. Through scientifically, the silver -based antibacterial mother grains, anti -ultraviolet mother grains, and co -concentration phosphorus are combined with flame retardant polyester resin to prepare to get pre -removal -oriented wires, and then go through through it.Add bullet deformation to produce low -bullet polyester deformation wires, and then enter the mixed spinning box spinning after measuring pump measuring pump meters to obtain a permanent antibacterial, ultraviolet and flame -retardant multi -functional polyesterFiber makes the application range of polyester fibers wider.

Description

technical field [0001] The invention relates to the technical field of polyester composite yarn, in particular to a high-strength polyester flame-retardant composite yarn and a preparation process thereof. Background technique [0002] The processed and woven products of knitwear are called textiles, which can be divided into three categories: clothing textiles, decorative textiles, and industrial products according to their uses. Clothing textiles include various textile fabrics for clothing, sewing threads, elastic bands, Textile accessories such as collar lining and lining and knitted garments, gloves, socks, etc. Decorative textiles can be divided into indoor products, bedding and outdoor products, including household cloth and restaurant bathroom products, such as: carpets, sofa covers, chairs , tapestries, patches, like covers, textiles, curtains, towels, tea towels, tablecloths, handkerchiefs, etc. Bedding includes bedspreads, sheets, quilt covers, quilt covers, blank...

AI Technical Summary

Problems solved by technology

From the perspective of polyester molecular composition, it is composed of short aliphatic hydrocarbon chains, ester groups, benzene rings, and terminal alcohol hydroxyl groups. There are no other polar groups in polyester molecules except for two terminal alcohol hydroxyl groups. Therefore, polyester fibers Very poor hydrophilicity, polyester molecules contain about 46% ester groups, ester groups can undergo hydrolysis and thermal cracking when the temperature is above 200 ° C, and saponolysis when encountering strong alkali will reduce the degree of polymerization. Washing powder has no effect on polyester; polyester molecules also contain aliphatic hydrocarbon chains, which can make polyester molecules have a certain flexibility, but because there are benzene rings in polyester molecules that cannot rotate internally, polyester macromolecules are basically rigid. Molecules and molecular chains are easy to maintain linear shape. Therefore, polyester macromolecules are easy to form crystals under this condition, so polyester has high crystallinity and orientation. Polyester has a wide range of uses and is widely used in the manufacture of clothing and industrial products. Because of its permanent flame retardancy, flame-retardant polyester has a wide range of applications. In addition to its irreplaceable role in industrial textiles, architectural interior decoration, and vehicle interior decoration, it also plays a lot of roles in the field of protective clothing. According to the national standard for flame retardant protective clothing, metallurgy, forestry, chemical industry, petroleum, fire protection and other departments should use flame retardant protective clothing. At present, people are developing product development in the fields of anti-ultraviolet, antibacterial or flame retardant, but only unilaterally. Fibers are modified to be anti-ultraviolet, antibacterial or flame retardant, but it cannot solve how to combine the three organically to obtain more fibers with a wide range of functional applications
