Embodiment 1

[0049] A trilobal bamboo charcoal viscose fiber is obtained by mixing bamboo charcoal pulp and viscose through pre-spinning injection, wet spinning and post-processing; the cross section of the fiber is trilobal, and the aspect ratio of the cross section is 10 : 1; Bamboo charcoal content is 0.1% of the total fiber weight, ammonia absorption rate ≥ 60%, air permeability ≥ 500mm / s, color fastness to washing 4 grades.

Embodiment 2

[0051] A trilobal bamboo charcoal viscose filament is obtained by mixing bamboo charcoal pulp and viscose through pre-spinning injection, wet spinning and post-treatment; the cross-section of the fiber is trilobal, and the aspect ratio of the cross-section is 200:1; bamboo charcoal content is 10% of the total fiber weight, ammonia absorption rate ≥ 60%, air permeability ≥ 500mm / s, color fastness to washing 5 grades, dry strength 1.6cN / dtex, dry elongation 18%, dry elongation Variation ≤ 8%.

Embodiment 3

[0053] A trilobal bamboo charcoal viscose filament is obtained by mixing bamboo charcoal pulp and viscose through pre-spinning injection, wet spinning and post-treatment; the cross-section of the fiber is trilobal, and the aspect ratio of the cross-section is 50:1; bamboo charcoal content is 2% of the total fiber weight, ammonia absorption rate ≥ 60%, air permeability ≥ 500mm / s, color fastness to washing 4 grades, dry strength 2.5cN / dtex, dry elongation 22%, dry elongation Variation ≤ 8%.

[0054] The preparation method of the bamboo charcoal slurry is as follows: adding non-foaming dispersant, bamboo charcoal powder, thickener and alkali into deionized water, stirring and grinding evenly.

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 trilobal bamboo charcoal viscose fiber and a production process thereof. It is characterized in that: the bamboo charcoal pulp is mixed with viscose by pre-spinning injection, and obtained by wet spinning and post-treatment; the cross section of the fiber is trilobal, and the aspect ratio of the cross section is 10~200:1; the bamboo charcoal The content is 0.1~10% of the total weight of the fiber, the ammonia absorption rate is ≥60%, the air permeability is ≥500mm / s, and the color fastness to washing is 4~5. The trilobal bamboo charcoal viscose fiber of the present invention has a large surface area of ​​the fiber cortex, and under the premise of maintaining the sterilization, deodorization, far infrared, and odor absorption effects of the bamboo charcoal viscose fiber, the hygroscopicity is better, and the additional value of the product can be greatly improved. , more comfortable to wear, and maximize the excellent characteristics of bamboo charcoal fiber.

Description

technical field [0001] The invention relates to the technical field of viscose in the textile industry, in particular to a trilobal 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 welco...
