A kind of flame-retardant 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 fiber, the invention provides a flame-retardant bamboo charcoal viscose fiber and a preparation method thereof. It is characterized in that: the flame-retardant bamboo charcoal solution is mixed with viscose by injection before spinning, and the finished product is obtained through wet spinning and post-processing. By weight, the flame retardant content in the fiber is 5-15%, and the bamboo charcoal content is 0.1-10%. , limiting oxygen index ≥ 28, ammonia absorption rate ≥ 50%, air permeability ≥ 500mm / s, color fastness to washing 4~5. The flame-retardant bamboo charcoal viscose fiber of the present invention is a new product, which not only has antibacterial, anti-ultraviolet, and deodorizing functions, but also has good air permeability, hygroscopicity, and long-lasting flame-retardant performance.

Description

technical field

[0001] The invention relates to the technical field of viscose in the textile industry, in particular to a flame-retardant 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 deepl...
