Abstract

The invention belongs to the technical field of fiber manufacturing, and more specifically relates to an antibacterial deodorizing nanometer fiber, and a preparation method thereof. The antibacterialdeodorizing nanometer fiber is prepared from, by weight, 22 to 26 parts of nanometer titanium dioxide, 30 to 35 parts of chitosan, 3 to 5 parts of rose flower, 55 to 60 parts of Glacial Acetic Acid, 2to 4 parts of single layer graphene, 2 to 3 parts of bamboo fiber micropowder, 1 to 2 parts of carboxymethylcellulose sodium, and 1 to 2 parts of garlic essential oil. The antibacterial deodorizing nanometer fiber possesses excellent bacteria killing and inhibiting and deodorizing effect; the antibacterial validity and broad spectrum activity of chitosan nanometer fiber are improved; the raw materials are relatively cheap; no high temperature treatment is needed in the preparation process; the preparation process is simple and convenient; cost is low; efficiency is high; no pollution is caused; and energy consumption is low.

Description

technical field [0001] The invention relates to the technical field of fiber manufacturing, and more specifically relates to an antibacterial and deodorizing nanofiber and a preparation method thereof. Background technique [0002] Chitosan is the second largest polysaccharide after cellulose on the earth, and it is also the only basic amino acid polysaccharide found in nature. Chitosan has good biocompatibility, biodegradability, and antibacterial properties, so it is Widely used in biomedical fields such as medical dressings, hemostatic supplies, anti-adhesion films, and tissue engineering scaffold materials. [0003] Chitosan has certain antibacterial properties, but does not have antibacterial broad-spectrum properties. Therefore, in order to increase the antibacterial properties of chitosan nanofibers, the prior art usually loads nano-silver antibacterial agents on chitosan nanofibers, such as, Chinese patent CN101297976A discloses a method for preparing an antibacteri...
