Abstract

The invention relates to the technical field of antibacterial fiber, in particular to a natural antibacterial carbon fiber and a preparation method. The preparation method of the natural antibacterialcarbon fiber includes the steps of: (1) extracting a Chinese herbal medicine to obtain a Chinese herbal medicine extracted liquid; (2) mixing the Chinese herbal medicine extracted liquid, a polymer emulsion and a foaming agent in an organic solvent to obtain a mixed emulsion, and then performing spinning to the mixed emulsion so as to obtain polymeric fiber; (4) carbonizing the polymeric fiber toobtain carbon fiber; and (5) subjecting the carbon fiber to activation in water vapor to obtain the carbon fiber for rapid graded purification of air. The carbon fiber obtained by the method providedby the invention not only has a developed pore structure, high activation yield and large specific surface area, but also has an excellent adsorption effect on harmful gases and particles in the air,and has a good inhibition effect on bacteria.

Description

technical field [0001] The invention relates to the technical field of antibacterial fibers, in particular to a natural antibacterial carbon fiber and a preparation method. Background technique [0002] Activated carbon is a porous carbon material with a large number of micropores. Its highly developed pore structure makes it have a large surface area, which can effectively remove color and odor, and can remove most organic pollutants and Certain inorganic substances, including certain toxic heavy metals, can also remove toxic and harmful gases in the air, achieving the effect of adsorption and purification. Activated carbon fiber (fibrous), the fiber is covered with micropores, its adsorption capacity for organic gases is several to dozens of times higher than granular activated carbon in air, 5 to 6 times higher in aqueous solution, and the adsorption rate is 100 to 1000 times faster. In the industry, use his super adsorption capacity to recover organic solvents, purify a...
