Preparation and Properties of PAN/PMIA Blended Nanofiber Composite Air Filter Paper Based on Electrostatic Spinning
PAN/PMIA blended nanofiber composite air filter paper was prepared by electrostatic spinning technology using air filter base pa-per as substrate,polyacrylonitrile(PAN)with high spinnable and meta-aramid(PMIA)with high performance as raw materials.By adjust-ing the mass ratio of two specialty fiber,a composite air filter paper with good filtration performance and high temperature resistance was pre-pared.The results showed that when the mass ratio of PAN to PMIA was 3:7,the filtration efficiency of PAN/PMIA blended nanofiber com-posite filter paper was 99.995％,the initial resistance was 79.01 Pa,and the dust capacity was 175 g/m2.After a series of heat treatment,the filtration efficiency of the composite filter paper could be maintained above 99.960％.
