Abstract

The invention discloses a preparation method of an antibacterial and sterile nano bamboo carbon fiber. The method comprises the steps that (1) nano bamboo carbon powder is added to an aqueous solution containing a polyacrylate dispersing agent; a nano bamboo carbon water-based dispersion liquid is obtained after wet grinding; (2) an additive is immersed in the nano bamboo carbon water-based dispersion liquid; a mixture is obtained and heated to boiling for some time; antibacterial and sterile modified nano bamboo carbon dispersion liquid is obtained; (3) a mixture of methyl methacrylate and methyl acrylate is added to the antibacterial and sterile modified nano bamboo carbon dispersion liquid; an initiating agent is dropped while stirring; microencapsulated modified nano bamboo carbon is prepared; and (4) the microencapsulated modified nano bamboo carbon is subjected to viscose fiber wet spinning, and the antibacterial and sterile nano bamboo carbon fiber is prepared. The nano bamboo carbon fiber is good in physical property, good in spinnability, and low in cost, and industrial production can be achieved easily.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a method for manufacturing antibacterial and sterilized nanometer bamboo charcoal fibers. Background technique [0002] With the improvement of people's living standards, people's requirements for clothing are getting higher and higher. The research and development of bamboo carbon fiber is catering to people's requirements. Bamboo charcoal has a strong adsorption capacity due to the special microporous structure on its surface and inside. The microporous structure can balance water and make it fully valued. [0003] The open patent CN101104960A applied by Shandong Hailong in 2007 discloses a bamboo charcoal cellulose fiber and its manufacturing method. The patent is to add nano-bamboo charcoal powder in the form of dry powder to the cellulose spinning stock solution with ionic liquid as the cellulose solvent , and spun into bamboo charcoal cellulose fibers by dry jet wet spi...
