Abstract

In order to meet the needs of customers in the product market and solve the problem of poor spinnability of the bamboo charcoal viscose fiber, the invention provides a photosensitive color-changing bamboo charcoal viscose fiber and a production process thereof. The characteristics of the photosensitive color-changing bamboo charcoal viscose fiber of the present invention are: by weight, the fiber contains 1-10% of photosensitizer, 0.1-10% of bamboo charcoal, ammonia absorption rate ≥ 50%, air permeability ≥ 500mm / s, washable color fastness Degree 4~5. The photosensitive color-changing bamboo charcoal viscose fiber of the present invention not only has antibacterial, anti-ultraviolet, and deodorizing functions, but also has good air permeability, hygroscopicity, very good wearability, good photochromic performance, and is light green or green under light. yellow-green.

Description

technical field [0001] The invention relates to the technical field of viscose in the textile industry, in particular to a photosensitive discoloration bamboo charcoal viscose fiber and a preparation method thereof. Background technique [0002] Bamboo charcoal is mainly composed of carbon, hydrogen, oxygen and other elements. It is hard, fine and porous, and has strong adsorption capacity. Excellent deodorizing, antiseptic, and odor-absorbing functions. Nano-scale bamboo charcoal powder also has good antibacterial and bactericidal effects, can absorb and neutralize the acidic substances contained in sweat, and achieve the effect of whitening the skin. Not only that, bamboo charcoal is also a very good emission material for far infrared and negative ions. Bamboo-charcoal blended health-care fiber can emit negative ions without damaging equipment during processing, which overcomes the serious disadvantage of grinding needles when processing fabrics with negative ion fibers,...
