Abstract

The invention provides a bamboo charcoal cellulosic fiber and a preparation method thereof. The fiber is obtained through the following steps: mixing bamboo charcoal pulp with spinning solution which is prepared by dissolving cellulose with ionic liquid, and spinning through a coagulating bath prepared by ionic liquid aqueous solution, wherein the content of the nano bamboo charcoal is 0.1-10 percent of the weight of the finished product fiber; the bamboo charcoal pulp is prepared from the following raw materials in percentage by weight: 5-25 percent of bamboo charcoal powder, 1-2 percent of bubbleless dispersant, 1-5 percent of a thickening agent, 4-6 percent of sodium hydroxide and the balance of de-ionized water. The preparation method has the characteristics of simple process, no equipment corrosion, small environmental pollution and high production efficiency; 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 cellulosic fiber raw material is provided for textiles.

Description

technical field [0001] The invention relates to the technical field of cellulose fiber production, in particular, the invention relates to a bamboo charcoal-containing cellulose fiber 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 po...
