| Abstract:In this study， the air filter paper was prepared using the Tencel fiber （beating degree 23°SR） as the raw material together with hardwood fiber improving the strength of air filter paper. The filtration performance of the prepared filter paper was then optimized through adding foaming agent in the pulp and coating cellulose nanofilament （CNF） on the surface and the physical and filtration performance of the air filter paper were further studied. The results showed that the air filter paper with Tencel fiber mass fraction of 60% possessed a filtration efficiency for PM2.5 of 98.97%， a decreased resistance pressure of 146.7 Pa， and a quality factor of 0.3119 Pa-1， exhibiting the best filtration performance. |
