Abstract

The invention relates to a negative ion elastic fiber and a preparation method thereof. A negative ion parent material and polyurethane fiber are mixed, wherein the negative ion parent material accounts for 8-20% the mass of the polyurethane fiber, the negative ion parent material is prepared from, by mass, 23% of silicon dioxide, 23% of tourmaline, 3.5% of attapulgite, 5.5% of zirconium dioxide, 4% of phosphorus pentoxide, 3.5% of aluminum oxide, 4.0% of rare earth ore, 26% of PP, 1.5% of an aluminum-titanium coupling agent, 4% of polyethylene wax, 1% of stearic acid and 1% of an excitant. The negative ion parent material and an organic solvent are mixed and stirred at high speed, and the polycaprolactone glycol, 1,4-butanediol and MDI are subjected to a polymerization reaction; the antioxidant, ultraviolet auxiliaries, dyeing auxiliaries and the lubricant are added, and sufficient stirring is performed to obtain a spinning solution; the spinning solution passes through a high temperature paved path and is subjected to roller drafting, oiling and winding and prepare the negative ion elastic fiber. The negative ion release amount of the negative ion elastic fiber is greatly increased.

Description

technical field [0001] The invention relates to the technical field of textile fibers, in particular to an anion elastic fiber and a preparation method thereof. Background technique [0002] Negative ion is a kind of far-infrared radiation material that is very beneficial to human health. The optimal wavelength of far-infrared rays suitable for human body absorption is 9.6 μm, while the wavelength of far-infrared rays radiated by negative ion mineral crystals is in the range of 2-18 μm, and the radiation power emission density is 0.04w / cm 2 Slightly higher, the above data can fully prove that the far-infrared rays radiated by negative ion mineral crystals are well coordinated with the human body and can be completely absorbed by the human body. In the medical field, negative ions are recognized as an effective means of killing germs and purifying the air. [0003] Negative ion elastic fiber can be widely used in clothes, bedding, etc. Negative ions can kill germs and contr...
