A kind of anti-ultraviolet bamboo charcoal viscose fiber and preparation method thereof

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 UV-resistant bamboo charcoal viscose fiber and a preparation method thereof. It is characterized in that: the anti-ultraviolet bamboo charcoal solution is mixed with viscose by injection before spinning, and the finished product is obtained through wet spinning and post-treatment. The anti-ultraviolet bamboo charcoal solution is formed by mixing anti-ultraviolet masterbatch and bamboo charcoal solution; The masterbatch contains anti-ultraviolet agent, by weight, the content of anti-ultraviolet agent in the fiber is 0.01~10%, the content of bamboo charcoal is 0.1~10%, the ultraviolet shielding rate is ≥95%, the ammonia absorption rate is ≥50%, and the air permeability is ≥500mm / s , Color fastness to washing 4~5 grades. The anti-ultraviolet bamboo charcoal viscose fiber of the present invention not only has anti-ultraviolet and deodorizing functions, but also has good air permeability and hygroscopicity, and the anti-ultraviolet effect is stronger than that of ordinary bamboo charcoal fibers, the breaking strength of the fibers is high, and the cost is low.

Description

technical field

[0001] The invention relates to the technical field of viscose in the textile industry, in particular to an anti-ultraviolet 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, and ...
