Abstract

The invention provides a bamboo charcoal viscose fiber and a preparation method thereof. The fiber is prepared by mixing bamboo charcoal pulp with viscose and then spinning, wherein the content of the nano bamboo charcoal is 0.1-10 percent of weight of the finished product fiber; the specific indexes of the bamboo charcoal viscose finished product are that the dry fracture strength is 1.6-3.5 cN/dtex, the dry breaking elongation is 16-20 percent, the dry strength variable coefficient CV is less than or equal to 18 percent, the dry breaking elongation variable coefficient CV is less than or equal to 8 percent, the flaw is less than or equal to 4 mg/100, the content of bamboo charcoal is 0.1-10 percent, the antibacterial ratio is greater than 99.9 percent, the ammonia adsorption rate is greater than 50 percent, and the color fastness to washing is class 4-5. The prepared fiber finished product has the characteristics of high strength, good adsorption performance, superior antibacterial effect, uniform and consistent color and strong color fixation; a high-quality bamboo charcoal viscose fiber raw material is provided for textiles.

Description

technical field [0001] The invention relates to the technical field of viscose fiber production, in particular, the invention relates to a viscose fiber containing bamboo charcoal and a preparation method thereof. Background technique [0002] Cellulose is a macromolecular polysaccharide composed of glucose, insoluble in water and general organic solvents, and is the main component of plant cell walls. Cellulose is the most widely distributed and most abundant polysaccharide in nature, accounting for more than 50% of the carbon content in the plant kingdom. Cellulose is also the oldest and most abundant natural polymer on the earth. It is inexhaustible and the most precious natural renewable resource for human beings. Hemp, wheat straw, straw, bagasse, etc. are all rich sources of cellulose. [0003] Bamboo charcoal is a kind of charcoal made of three-year-old moso bamboo as raw material and fired at a high temperature of nearly 1,000 degrees. Bamboo charcoal has a porous...
