Abstract

The invention provides an anti-ultraviolet bamboo charcoalviscose fiber and a preparation method thereof in order to meet demands of clients in a product market and solve the problem that the conventional bamboo charcoalviscose fiber is poor in spinning property. The anti-ultraviolet bamboo charcoalviscose fiber is characterized by being obtained by mixing an anti-ultraviolet bamboo charcoal solution with mucilage glue through spinning before injection, and carrying out wet spinning and post-treatment, wherein the anti-ultraviolet bamboo charcoal solution is formed by mixing an anti-ultraviolet masterbatches and a bamboo charcoal solution; the anti-ultraviolet masterbatches contain an anti-ultraviolet agent. The fiber comprises the components by weight percent: 0.01-10 percent of the anti-ultraviolet agents and 0.1-10 percent of bamboo charcoal; the ultraviolet shielding rate is more than or equal to 95 percent, the ammonia absorption rate is more than or equal to 50 percent, and the air permeability is more than or equal to 500mm/s; the color fastness to washing is of 4-5 level. The anti-ultraviolet bamboo charcoalviscose fiber has functions of ultraviolet prevention and deodorization and is high in air permeability and absorptivity; furthermore, the anti-ultraviolet effect of the anti-ultraviolet bamboo charcoalviscose fiber is better than that of the common bamboo charcoal fiber; the breaking strength of the fiber 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 is dee...
