Manufacturing method of high-elasticity flame-retardant polyester fiber

Abstract

The invention discloses a manufacturing method of a high-elasticity flame-retardant polyester fiber. The manufacturing method comprises fully mixing layered double hydroxide, alga carbon fibers, silica, zirconium dioxide and 18-22 parts of zinc oxide, thoroughly drying the modified nanometer powder precipitates, carrying out full grinding again to obtain modified functional nanometer powder, fully mixing 50 parts of fully dried polyester PTT particles and 8-10 parts of the modified functional nanometer powder, adding 0.6-0.8 parts of a titanate coupling agent into the mixture to obtain a co-mixture, wherein the alga carbon fibers are prepared from alga carbon particles, polyphenylene sulfide, polysulfonamide and a polyester solution, and carrying out melt spinning on far-infrared master batches, polyethylene glycol terephthalate particles and 50 parts of the polyester PTT particles by a melt spinning machine to obtain the polyester PTT fibers. The polyester PTT fiber has high strength and breaking elongation performances, can promote human metabolism, can reduce fiber brittleness and can improve fiber extension performances.

Description

technical field [0001] The invention relates to a method for manufacturing high-elastic flame-retardant polyester fibers, which belongs to the technical field of textile fabrics. Background technique [0002] With the development of science and technology, various functional textiles are constantly appearing, such as various functional fibers such as antibacterial, anti-ultraviolet, far-infrared, and flame-retardant are constantly being developed. The far-infrared functional fiber is a relatively new functional textile material that has gradually been recognized by customers this year. It has the functions of keeping warm, health care, promoting human body circulation and improving human immunity. Far-infrared functional fibers can be used to develop a variety of heat storage products and medical products with functions such as heat preservation and health care, such as underwear, close-fitting thermal clothing, down jacket fillings, bedspreads, bed sheets, etc. [0003] In...

AI Technical Summary

Problems solved by technology

[0005] In practical applications, although there are many far-infrared functional fibers at this stage, each far-infrared functional nanomaterial can only absorb radiation within a specific frequency, and the absorption wave is narrow and cannot effectively convert external radiation energy.

[0006] At present, although there are far-infrared functional fibers made by blending single-component nanometer far-infrared materials and PTT, they have disadvantages such as unstable far-infrared function, low fiber strength, narrow infrared conversion rate and wave absorption frequency, and poor flame retardancy.
