▎ 摘  要

NOVELTY - Preparing non-woven fabric comprises obtaining modified graphene, primary graphene polyester master batch raw material, graphene polyester masterbatch, micro-capsule electret raw material and high-energy electret master batch, melting, spinning, forming net, winding and cutting. The modified grapheme is obtained by uniformly mixing the graphene and hexagonal boronnitride according to mass ratio of 5-6: 1, adding into nano particles with titanium dioxide, silicon dioxide, polyvinyl amine, mixing uniformly, adding into absolute ethylalcohol, performing microwave oscillation at 80-80 degrees Celsius, controlling the microwave oscillation frequency of the microwave oscillation to 20-30 kHz for 10-15 minutes. USE - The fabric is useful for sterilizing and bacteriostasis mask. ADVANTAGE - The fabric has material resistance, filtering efficiency, antibacterial and persistent bacteriostasis, filtering efficiency of 1 micron and inner micro dust can reach 97-98.6%
