▎ 摘　　要

NOVELTY - An air filter material comprises coconut carbon fiber layer, graphene oxide fiber layer and basalt fiber layer in order, where graphene oxide fiber layer is provided between coconut carbon fiber layer and basalt fiber layer. Antibacterial agent is sprayed over the fiber layers and processed. USE - Air filter material for use in 3D vehicles for controlling bacteria chosen from Escherichia coli, Staphylococcus aureus and Bacillus subtilis. ADVANTAGE - The air filter material can be manufactured simply, realizes large-scale automation production, has antibacterial rate of 99.9% or more and prolongs usage time without reduction in antibacterial effect in 3D vehicles. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing an air filter material.
