High-heat-conductivity dehumidifying cool fiber and preparation process thereof

Abstract

The invention provides a high-heat-conductivity dehumidifying cool fiber and a preparation process thereof. The process comprises the following steps: S1, sequentially crushing large granular siliconcarbide for three times to obtain silicon carbide primary powder; S2, taking absolute ethyl alcohol as a solvent, taking polyvinylpyrrolidone as a modifier, adding the silicon carbide primary powder into the solvent, and carrying out ball milling by adopting a high-energy ball milling method to obtain silicon carbide powder; and S3, dispersing 1-5wt% of the silicon carbide powder in a spinnable spinning solution to form a mixed spinning solution, wherein the spinning solution comprises a chemical fiber spinning solution and a regenerated cellulose spinning solution; and S4, spinning and post-processing the mixed spinning solution to obtain the high-heat-conductivity dehumidifying and cooling fiber. According to the high-heat-conductivity dehumidifying cool fiber prepared by the method, silicon carbide is used as a raw material, cool and non-cold elements are released to rapidly conduct excess heat of a body, and an effect of instantly cooling skin is achieved.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a fiber with high thermal conductivity, moisture removal and cool feeling and a preparation process thereof. Background technique [0002] Silicon (Si) is widely distributed in nature and contains about 27.6% in the earth's crust. It is the second most abundant element after oxygen in the earth's crust and belongs to metalloid elements. Silicon carbide is also called moissanite. Pure silicon carbide is a colorless and transparent crystal. Its material has high temperature strength, strong oxidation resistance, good wear resistance, good thermal stability, small thermal expansion coefficient, high thermal conductivity and high hardness. As well as thermal shock resistance and chemical corrosion resistance, it is widely used in aerospace, nuclear energy, national defense, military and civil and other fields. The structure of silicon carbide, similar to that of diamond, is an atomic crystal...
