NOVELTY - Preparing non-woven fabric with bacteriostatic effect involves utilizing biomass cellulose to prepare biomass graphene, and grinding the biomass graphene into powder for subsequent use, blending the biomass graphene with polyester powder, drying, extruding and granulating to obtain biomass graphene master batch. The dispersant and surfactant are added when described biomass graphene and described polyurethane powder blend, where the mass ratio of described biomass graphene and polyurethane powder, dispersant and surfactant is 10:(30-40):(6-7.5):(2.5-5). The particle diameter of the biomass graphene master batch is 80-160 nanometer. The biomass graphene master batch is blend with polyurethane powder, spin through a spinneret, and collected and spin to obtain biomass graphene polyester fibers. The naturally grown bamboo is taken, make bamboo fibrils by slicing and refining the bamboo, crushed and decomposed USE - Method for preparing non-woven fabric with bacteriostatic effect ADVANTAGE - The method provides non-woven fabric with strong anti-bacterial-bacteriostatic function. The production process is very environment-friendly, and moisture absorption and ventilation property of the bamboo fiber anti- bacterial ventilation property, after blending with the biomass graphene polyester fiber, improve the wet strength of the whole in a certain degree. The bamboo fiber is directly extracted from the bamboo, by mechanical rolling, soaking and cooking to remove the surface, so as to extract the limit. DETAILED DESCRIPTION - Preparing non-woven fabric with bacteriostatic effect involves utilizing biomass cellulose to prepare biomass graphene, and grinding the biomass graphene into powder for subsequent use, blending the biomass graphene with polyester powder, drying, extruding and granulating to obtain biomass graphene master batch. The dispersant and surfactant are added when described biomass graphene and described polyurethane powder blend, where the mass ratio of described biomass graphene and polyurethane powder, dispersant and surfactant is 10:(30-40):(6-7.5):(2.5-5). The particle diameter of the biomass graphene master batch is 80-160 nanometer. The biomass graphene master batch is blend with polyurethane powder, spin through a spinneret, and collected and spin to obtain biomass graphene polyester fibers. The naturally grown bamboo is taken, make bamboo fibrils by slicing and refining the bamboo, crushed and decomposed, cooked bamboo silk, degummed and carded the fibers. The biomass graphene polyester fiber and the bamboo fiber are woven into a non-woven fabric by a blending process, and then the woven fabric is cut into a mask cloth structure. The mass ratio of the biomass graphene polyester fibers and bamboo fibrils is (70%-80%):(20%-30%).
