A kind of bamboo charcoal viscose fiber and preparation method thereof

Abstract

The invention provides a bamboo charcoal viscose fiber and a preparation method thereof. The fiber is obtained by spinning after mixing bamboo charcoal slurry and viscose, and the content of the nano-bamboo charcoal is 0.1% to 10% of the weight of the finished fiber. The specific indicators of bamboo charcoal viscose fiber finished products include: dry breaking strength of 1.6~3.5cN / dtex, dry breaking elongation of 16~20%, dry strength coefficient of variation CV≤18%, dry breaking elongation coefficient of variation CV≤8 %, defect ≤ 4mg / 100, bamboo charcoal content 0.1-10%, antibacterial rate > 99.9%, ammonia adsorption > 50%, color fastness to washing 4-5. The finished fiber produced by the invention has the characteristics of high strength, good adsorption performance, excellent antibacterial effect, uniform color and strong color fixation, and provides high-quality bamboo charcoal viscose fiber raw materials for making 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...

AI Technical Summary

Problems solved by technology

[0009] The above patent information shows that because bamboo charcoal micropowder is added to the spinning solution, and the particle size of the micropowder is about 0.5 microns, and the dispersion stability of bamboo charcoal is poor, when the bamboo charcoal micropowder contacts with viscose, it is easy to agglomerate the dispersed particles, resulting in Viscose is not easy to filter, the spinnability is reduced, the spinning is easy to break, and the mechanical and physical properties of the fiber are poor, which in turn affects the quality of the fiber and the antibacterial and moisture absorption properties of bamboo charcoal.
