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 nano-copper bamboo charcoal viscose fiber and a preparation method thereof. It is characterized in that: the nano-copper bamboo charcoal solution is mixed with viscose by pre-spinning injection, and the finished product is obtained through wet spinning and post-processing. By weight, the nano-copper content in the fiber is 0.01~5%, the bamboo charcoal content is 0.1~10%, the ammonia absorption rate is ≥50%, the air permeability is ≥500mm / s, and the color fastness to washing is 4~5. The nano-copper bamboo charcoal viscose fiber of the present invention not only has anti-ultraviolet and deodorizing functions, but also has good air permeability and absorbency, and the antibacterial effect is stronger than that of ordinary bamboo charcoal fiber, the fiber has high breaking strength and low cost.

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 fav...
