NOVELTY - An automobile air conditioning filter core material includes a specific protection net, dust removal net, filter net and preset protection net from top to bottom. The specific protective net and preset protective net are nylon material fabrics, and edges are sewn together to form a protective cover that protect the dust removal net and filter net located in the protective cover. The dust removal net is a polyurethane fiber fabric. The filter cotton material includes 50-60 wt.% activated carbon, 10-20 wt.% foam ceramic particles and 20-30 wt.% graphene-treated animal hair. USE - Automobile air-conditioning filter core material. ADVANTAGE - The automobile air-conditioning filter core material can filter particles having a particle size of less than 2 mm in the air to achieve excellent air filtration effect. The automobile air-conditioning filter core material is not easy to grow bacteria, can be used repeatedly after cleaning, and has low economic cost. DETAILED DESCRIPTION - An automobile air conditioning filter core material includes a specific protection net, dust removal net, filter net and preset protection net from top to bottom. The specific protective net and preset protective net are nylon material fabrics, and edges are sewn together to form a protective cover that protect the dust removal net and filter net located in the protective cover. The surface of fabric of specific protective net has a pore size of 400-500 mu m, and wire diameter of 70-80 mu m. The dust removal net is a polyurethane fiber fabric and has a plain weave structure with mesh meridional density of 27.82-28.46 roots/cm, zonal density of 27.6-29.1 root/cm, aperture of 301-311 microns and wire diameter of 51-57 microns. The polyester fiber has strength of 4.0-5.2 CN/dtex, elongation of 18-25%, and boiling water shrinkage rate of 8-12%. The filter cotton material includes 50-60 wt.% activated carbon, 10-20 wt.% foam ceramic particles, 20-30 wt.% graphene-treated animal hair. The graphene-treated animal hair has animal hair at a pH of 2-3, and is obtained by immersing in graphene suspension with 1-2 mol/L copper ion or silver ion for 1-2 hours, taking out, draining, quickly drying by hot air.
