Functional copper sulfide composition and functional fiber prepared from same

Abstract

The present invention relates to a functional copper sulfide composition and a functional fiber prepared from same, and more particularly, to a functional copper sulfide composition comprising a copper salt, a metal salt, a reducing agent, a sulfur compound, a catalyst, a polyvalent amine, an alkaline compound, and a pH adjusting agent, and a functional fiber prepared by treating a fiber with the composition. The present invention may provide a functional fiber which maintains the color thereof and has excellent conductivity, laundering resistance, washing resistance, durability, moisture resistance, alkali resistance, etc., even after repeated washings or long-term usage. Moreover, the functional fiber according to the present invention is excellent in terms of antibacterial and deodorizing properties, emission of far infrared radiation, scar treatment, skin aging prevention, heat storage and heat insulation, radiation shielding, and static removal, and may thus be widely used in clothing applications such as clothes, socks, gloves, bands, abdominal supports, masks, hats, bandages, scarves, hospital gowns, etc., industrial applications such as bedding, burn pads, industrial filters, fillers, etc., and military applications.

Description

technical field [0001] The present invention relates to a functional copper sulfide composition and a functional fiber prepared therefrom, in more detail, to a composition comprising copper salt, metal salt, reducing agent, sulfide, catalyst, polyvalent ammonium, basic compound and pH regulator A functional copper sulfide composition and a functional fiber prepared by treating the composition in a fiber. Background technique [0002] Most synthetic fibers and natural fibers generate static electricity due to friction between fibers or between fibers and the skin. lead to various problems. [0003] In order to solve the problem of static electricity generated in fibers, research and development are underway to treat fibers with antistatic agents or to impart conductivity to fibers. [0004] The method of treating fibers with an antistatic agent has the advantages of low cost and simple process, but has the disadvantage that the antistatic effect is significantly reduced dur...

AI Technical Summary

Problems solved by technology

[0006] The method of preparing conductive fibers by mixing carbon black or metal powder with polymer has the following disadvantages: not only can carbon black or metal powder not form a uniform mixture with polymer, but also in the process of fiberization by spinning, The strength, elongation, and thermal properties of the fiber are greatly reduced

[0013] However, the above-mentioned documents relate to the technology of imparting electrical conductivity by coordinating the fiber with copper sulfide. The conductive fiber prepared by the above-mentioned method has partially improved conductivity, but when it is repeatedly washed or used for a long time, it is not compatible with the fiber. The copper sulfide bonded on the surface is detached, so that the fiber color is seriously changed, and the conductivity, washing resistance, cleaning resistance, durability, moisture resistance, alkali resistance, etc. are sharply reduced

[0014] Moreover, the above-mentioned conductive fibers cannot simultaneously satisfy antibacterial, deodorant, far-infrared radiation, wound healing, skin aging prevention, heat storage and heat preservation, electromagnetic wave shielding, static removal, etc. problems in the field of clothing, industry and military supplies
