A kind of hollow bamboo charcoal viscose fiber and its production process

Abstract

Aiming at the above technical problems, the present invention provides a hollow bamboo charcoal viscose fiber and a production process thereof. It is characterized in that: the nano-copper bamboo charcoal solution is mixed with viscose by injection before spinning, and the hollow bamboo charcoal viscose fiber is obtained through wet spinning and post-treatment. By weight, the bamboo charcoal content in the fiber is 0.1-10%, and the hollowness is 10% ~30%, elongation 16~20%, ammonia absorption rate ≥60%, air permeability ≥500mm/s, color fastness to washing 4~5. The hollow bamboo charcoal viscose fiber of the present invention greatly improves the added value of the product under the premise of maintaining the sterilization, deodorization, far-infrared, and odor absorption effects of the bamboo charcoal viscose fiber, and maximizes the excellent characteristics of the bamboo charcoal fiber.

Description

technical field [0001] The invention relates to the technical field of viscose in the textile industry, in particular to a hollow bamboo charcoal viscose fiber and a production process 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 welcome...

AI Technical Summary

Problems solved by technology

The elongation of the hollow bamboo charcoal cellulose fibers in this patent is too low, and the fibers are easily broken; the preparation process blends cellulose sulfonate, bamboo charcoal powder, sodium bicarbonate, sodium hydroxide and water, and then filters, defoams, and matures There are multiple processes, many processes, long processes, and a residence time of 10-20 hours. The process is long, and the bamboo charcoal powder is black, which pollutes pipes and equipment, and wastewater treatment is difficult; for a long time, the additives of bamboo charcoal powder and sodium bicarbonate It has a great influence on the stability of viscose, resulting in fluctuations in maturity, unstable product quality, and poor spinnability
