A kind of antistatic bamboo charcoal viscose fiber and preparation method thereof

Abstract

In order to make up the blank of the current antistatic bamboo charcoal viscose fiber and solve the problem of poor spinnability of the current bamboo charcoal viscose fiber, the invention provides an antistatic bamboo charcoal viscose fiber and a preparation method thereof. It is characterized in that the graphite content in the fiber is 1-10%, the bamboo charcoal content is 0.1-10%, the volume resistivity is less than 1010Ω·cm, the ammonia absorption rate is ≥50%, the air permeability is ≥500mm / s, and the color fastness to washing is 4-5 class. The antistatic bamboo charcoal viscose fiber of the present invention not only has antibacterial, anti-ultraviolet and deodorizing functions, but also has good air permeability and hygroscopicity, soft hand feeling, and remarkable and long-lasting antistatic effect.

Description

technical field

[0001] The invention relates to the technical field of viscose in the textile industry, in particular to an antistatic 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 deeply we...
