摘要：
Cellulose acetate porous ultrafine fibers were produced from highly volatile solvent system by electro-spinning. Three types of porous cellulose acetate fibers, including particle-like fibers, ribbon-like fibers and cylindrical fibers, were prepared by changing the concentration of solvent. The fiber surface morphology was studied by scanning electron microscopy (SEM), the conductivity of the cellulose acetate solutions was measured by conductivity meter, the viscosity of the solutions was measured by viscometer. A test-board was employed to investigate the effects of fiber morphology, spinning time and air flow on the filtration performance of composite filter materials. The results show that with increase of the cellulose acetate concentration, the morphologies of porous fibers change to "particle-like fibers", "ribbon-like fibers" and "cylindrical fibers", respectively. "Ribbon-like fibers" and "cylindrical fibers" were beneficial to the filtration efficiency of composite filter materials, the "particle-like fibers" were beneficial to decrease the filtration resistance. As increase of the spinning time, the filtration efficiency and the filtration resistance all increase. With increase of the air flow, the filtration efficiency of composite filter materials decreases slightly, while the filtration resistance increases obviously. © 2017, Editorial Board of Polymer Materials Science & Engineering.
