Abstract

The invention discloses a flame-retardant elastic PET/PTT composite fiber. The flame-retardant elastic PET/PTT composite fiber comprises 100 parts of polyester PTT particles, 20-30 parts of polyethylene glycol terephthalate particles, 8-10 parts of functional nanometer powder, and 0.6-0.8 parts of a titanate coupling agent. The functional nanometer powder comprises 38-42 parts of layered double hydroxide, 18-22 parts of alga carbon fibers, 9-12 parts of silica, 9-12 parts of zirconium dioxide and 18-22 parts of zinc oxide. The layered double hydroxide is prepared by mixing sodium carbonate and sodium hydroxide according to a mole ratio of 1: 16, grinding the mixture at the room temperature for 10min to obtain a first mixed liquid and mixing aluminum nitrate, magnesium nitrate, polyamide and phosphite according to a weight part ratio of 1: 3: 1: 0.5 to obtain a second mixed liquid. The flame-retardant elastic PET/PTT composite fiber has high strength and fracture elongation performances, can promote human metabolism, can make the human body healthy, can promote human body blood circulation and has heat insulation effects.

Description

technical field [0001] The invention relates to an elastic polyester PTT fiber, 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 the electromagnetic spectrum, infrared ra...
