NOVELTY - Degradable antibacterial nanofiber non-woven fabric composite filter material comprises three-layer structure, where first layer facing wind direction is nanofiber filter layer, the second layer is nanomaterial antibacterial layer, and third layer is substrate layer. USE - Degradable antibacterial nanofiber non-woven fabric composite filter material. ADVANTAGE - The material is environment-friendly, and has high filtering efficiency, and reduces filtering resistance and improves antibacterial effect for about greater than 99%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of degradable antibacterial nanofiber non-woven fabric composite filter material comprising coating layer of adhesive on base layer, using electrostatic spray process to coat base layer with antibacterial microspheres to make nanomaterial antibacterial layer, , using electrostatic spinning process to prepare nanofiber filter layer on nanomaterial antibacterial layer, hot-rolling composite material and compounding.
