Abstract

The invention provides a bamboo charcoal viscose fiber rich in nano-copper and a preparation method of the bamboo charcoal viscose fiber in order to meet demands of clients in a product market and solve the problem that the conventional bamboo charcoal viscose fiber is poor in spinning property. The bamboo charcoal viscose fiber rich in nano-copper is characterized by being prepared by mixing a nano-copper bamboo charcoal solution with viscose throug injection before spinning, and carrying out wet spinning and post-treatment; the nano-copper bamboo charcoal solution is formed by mixing masterbatches containing the nano-copper and a bamboo charcoal solution. The fiber comprises the components by weight percent: 0.01-5 percent of nano-copper and 0.1-10 percent of bamboo charcoal; the ammonia absorption rate is more than or equal to 50 percent; the air permeability is more than or equal to 500mm / s; the color fastness to washing is of 4-5 level. The bamboo charcoal viscose fiber rich in the nano-copper has functions of ultraviolet prevention and deodorization and is high in air permeability and absorptivity; furthermore, the antibacterial effect of the bamboo charcoal viscose 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 a bamboo charcoal viscose fiber rich in nanometer copper. 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 deeply welcomed and favored b...
