Problems solved by technology

[0006] The bamboo charcoal viscose fiber of prior art gained, because wherein added bamboo charcoal micropowder, and micropowder particle size is bigger, at 0.5~5 μ m, add the poor dispersion stability of bamboo charcoal, agglomeration easily takes place, causes production process spinnability poor, spinning Silk is easy to break, there are many defects in the finished product, and the physical and mechanical properties of the fiber are low, resulting in low performance of subsequent textile processing and low grade of the final product

Embodiment 1

[0021] One-time configuration of bamboo charcoal slurry. Use bamboo charcoal with a particle size of 125nm, add dialkyl dimethyl ammonium chloride to the bamboo charcoal by 0.3% of the bamboo charcoal amount, add polysiloxane quaternary ammonium salt by 0.5% of the bamboo charcoal amount, and then add deionized water to configure into 25% bamboo charcoal slurry.

[0022] Using bamboo pulp to prepare viscose, the main steps include: dipping→pressing→crushing→aging→yellowing→dissolving. The difference from the conventional process is that the denaturant alkyl polysaccharide is added during the dissolution process of cellulose xanthate Amine, denaturant adding amount is 2% of alpha cellulose weight.

[0023] Secondary configuration of bamboo charcoal slurry. Add the dissolved viscose according to 6 times the weight of the bamboo charcoal slurry, place it in a ball mill, and mill it for 90 minutes.

[0024] Preparation of dope for viscose spinning. The bamboo charcoal slurry o...

Embodiment 2

[0028] Use bamboo charcoal with a particle size of 95nm, add dialkyl dimethyl ammonium chloride to the bamboo charcoal according to 0.2% of the bamboo charcoal amount, add sodium tripolyphosphate according to 1% of the bamboo charcoal amount, and then add deionized water to configure 20% bamboo charcoal slurry.

[0029] The viscose is prepared with bamboo pulp, and a denaturant alkyl polyamine is added in the dissolving process of cellulose xanthate, and the addition amount is 2% of the weight of cellulose.

[0030] Add the dissolved viscose according to 8 times of the bamboo charcoal slurry, put it in a ball mill, and ball mill for 120min;

[0031] After ball milling finishes, above-mentioned mixture is 16% of fiber weight by bamboo charcoal, mixes viscose glue and stirs evenly before the defoaming in the mature process of cellulose viscose, above-mentioned viscose that mixes is through continuous defoaming, filtration, obtains Viscosity 70s, maturity 28ml (10% NH 4 Cl), de...

Embodiment 3

[0035] Be the bamboo charcoal of 85nm with particle diameter, in bamboo charcoal, add polyalkyl trimethylammonium chloride by 0.8% of bamboo charcoal amount, add dispersing agent sodium tripolyphosphate by 0.9% of bamboo charcoal amount, add deionized water again, configure 22% bamboo charcoal slurry;

[0036] Prepare viscose with bamboo pulp, and add denaturant alkylpolyamine in the dissolving process of cellulose xanthate, the addition amount is 2% of cellulose weight;

[0037] Add the dissolved viscose according to 9 times of the bamboo charcoal slurry, put it in a ball mill, and ball mill for 120min;

[0038]After ball milling finishes, above-mentioned mixture is made 25% of fiber weight by bamboo charcoal, is mixed with viscose before the defoaming in the mature process of cellulose viscose and stirs evenly, and above-mentioned mixed viscose is through continuous defoaming, filtration, obtains Viscosity 66s, maturity 25ml (10% NH 4 Cl), degree of esterification 40 conta...

Abstract

A bamboo-carbon viscose fiber and its production are disclosed. It consists of bamboo pulp dregs and nano-bamboo carbon 4-30wt%, the grain size is 75-150nm, final-product fiber strength is 1.7-3.0cN / dtex, extensibility is 9-18%. It adopts viscose coagulation bath composite modifying technology, it has excellent antibacterial, far-infrared health care and deodorization functions. It has better fiber strength and spinning handling property. It's cool, refined and no environmental pollution and can be used for summer clothing production and non-woven industries.

Description

technical field [0001] The invention relates to the technical field of viscose fiber, and the invention also relates to a production method of viscose fiber. Background technique [0002] The application number is CN200610037895 bamboo charcoal viscose fiber and its manufacturing method discloses bamboo charcoal viscose fiber and its manufacturing method. The bamboo charcoal viscose fiber contains bamboo charcoal micropowder and bamboo vinegar, and its manufacturing method includes a glue making process and a spinning process. In the glue making process, viscose solution and bamboo charcoal micropowder emulsion are prepared. The preparation of bamboo charcoal micropowder emulsion is after adding dispersing agent and bamboo charcoal micropowder in deionized water, stirring until obtaining evenly dispersed bamboo charcoal micropowder emulsion, in the spinning process, viscose solution and described bamboo charcoal micropowder emulsion are mixed uniformly, and then sent to Spi...
