Embodiment 1

[0025] The raw materials used are 70% bamboo chemical pulp and 30% cotton chemical pulp. After the yellowing is finished, add 0.8 micron particle size and 0.5% Naina white crystal pulp with the dissolving solution. A viscose solution is obtained. The viscose solution is filtered through channels I and II, continuously degassed and filtered through channel III to obtain a spun viscose solution, and the spun viscose solution is introduced into an acid bath. The condition is: H 2 SO 4 110g / L, Na 2 SO 4 325g / L, Zn 2 SO 4 10.8g / L, spun in a coagulation bath with a temperature of 50.5°C, and after post-treatment and drying, high-whiteness bamboo charcoal viscose fibers were obtained.

[0026] The whiteness of the obtained high-whiteness bamboo charcoal viscose fiber is 65%, the antibacterial value (adopting JLS L1902 standard) is 3.5, the far-infrared emissivity is 86%, and the negative oxygen ion is 4000 / cubic centimeter.

Embodiment 2

[0028] The raw material that adopts is the bamboo chemical pulp that accounts for 90% by weight and the wood chemical pulp of 10%, adds particle diameter 3.6 microns along with dissolving liquid after yellowing finishes, and accounts for the Naina white crystal slurry of 5.0% of first kind of cellulose weight The viscose solution is obtained, the viscose solution is filtered through I and II channels, continuous defoaming and III channel filtration to obtain the spinning viscose collagen solution, and the spinning viscose collagen solution is introduced into the acid bath condition as follows: H 2 SO 4 116g / L, Na 2 SO 4 328g / L, Zn 2 SO 4 10.8g / L, spun in a coagulation bath with a temperature of 50.5°C, and after post-treatment and drying, high-whiteness bamboo charcoal viscose fibers were obtained.

[0029] The whiteness of the obtained high-whiteness bamboo charcoal viscose fiber is 67%, the bacteriostasis value (using JLS L1902 standard) is 3.8, the far-infrared emissivi...

Embodiment 3

[0031] The raw material that adopts is the bamboo chemical pulp that accounts for 100% by weight, adopts the pre-spinning injection method, before the spinning process starts after the filtration process finishes, uses the syringe to add particle size 5.0 microns to the spinning viscose collagen liquid, accounting for the first fiber 10.0% Naina white crystal slurry by weight, and the spinning viscose collagen solution is introduced into the acid bath condition as: H 2 SO 4 120g / L, Na 2 SO 4 335g / L, Zn 2 SO 4 11.2g / L, spun in a coagulation bath with a temperature of 51.5°C, and after post-treatment and drying, high whiteness bamboo charcoal viscose fibers were obtained.

[0032] The whiteness of the obtained high-whiteness bamboo charcoal viscose fiber is 68%, the bacteriostasis value (using JLS standard) is 4.0, the far-infrared emissivity is 87%, and the negative oxygen ion is 4800 / cubic centimeter.

Abstract

The invention provides a manufacturing method of a high-whiteness bamboo-charcoal viscose fiber, which comprises the following steps: soaking the raw materials mainly comprising bamboo chemical fiber pulp, squeezing, pulverizing, aging, sulfidizing, dissolving, degassing, filtering, spinning into yarn, post-processing and drying; and in the course of processing, adding nano white-crystal pulp, wherein the nano white-crystal pulp accounts for 0.5-10% of the alpha cellulose by weight. In the invention, the nano white-crystal pulp is added in the course of manufacturing the bamboo-charcoal viscose fiber to manufacture the high-whiteness bamboo-charcoal viscose fiber. The prior bamboo-charcoal viscose fiber can be only black or grey; however, the high-whiteness bamboo-charcoal viscose fiber has high whiteness which is greater than or equal to 60%. The high-whiteness bamboo-charcoal viscose fiber can be colored with various dyes, and has the functions of bacterial inhibition, far infrared emission and negative oxygen-ions, thereby having wide application range.

Description

technical field [0001] The invention relates to the technical field of viscose fiber, in particular to a high-whiteness bamboo charcoal viscose fiber and a manufacturing method thereof. Background technique [0002] Bamboo charcoal is an environmentally friendly material developed by bamboo resources. It is made of bamboo after a high-temperature drying and carbonization process at 800 ° C to 1200 ° C. Bamboo charcoal has strong adsorption and decomposition ability, can absorb moisture and dry, deodorize and antibacterial, and can generate a large amount of negative ions. [0003] The manufacture of bamboo charcoal viscose fiber is based on nanotechnology. Firstly, the bamboo charcoal is micronized, and then the nano-scale bamboo charcoal micropowder is processed by high-tech technology, and then combined with the chemical fiber preparation process, spinning and forming, the multifunctional bamboo charcoal can be prepared. Viscose fiber. Bamboo charcoal viscose fiber is si...
