Elastic dacron double-component PTT composite fibers having far infrared function and based on biobased material

Abstract

The invention discloses elastic dacron double-component PTT composite fibers having a far infrared function and based on a biobased material. The elastic dacron double-component PTT composite fibers having the far infrared function are prepared from the following components: 100 parts of dacron PTT particles, 80 parts of PET (Polyethylene Terephthalate) particles, 8-10 parts of functional nano powder and 0.6-0.8 part of a titanate coupling agent; the functional nano powder is further prepared from the following components: 38-42 parts of layered double hydroxide, 18-22 parts of seaweed carbon fibers, 9-12 parts of silicon dioxide, 9-12 parts of zirconium dioxide and 18-22 parts of zinc dioxide; and the layered double hydroxide is obtained by grinding sodium carbonate and sodium hydroxide at the substance amount ratio of 1 to 16 at room temperature for 10 minutes to obtain a first mixed solution, and mixing aluminum nitrate, magnesium nitrate, polyamide and phosphite ester at the weight ratio of 1 to 3 to 1 to 0.5 to obtain a second mixed solution. The elastic dacron double-component PTT composite fibers have high strength and breaking elongation performance and can be used for promoting vigorous metabolism of human bodies, so that the bodies are healthy and the body blood circulation is promoted; and the elastic dacron double-component PTT composite fibers have a hot heat preservation effect.

Description

technical field [0001] The invention relates to a far-infrared functional elastic polyester two-component PTT composite 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. [000...

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.
