Abstract

The pore shape of spunbonded nonwovens and its influence on the filtering quality were investigated in this study. An index named the filtration index (FI) was first proposed to characterize the performance of the higher filtration efficiency against the lower pressure drop of spunbonded nonwovens. A parameter called plump degree was used to characterize the pore shape and was measured by applying digital image processing technology. The effect of pore plump degree on FI was discussed. The results show that FI decreases with the increase of pore plump degree and showed a significant linear dependence (correlation coefficient R = 0.96684). This work can provide a theoretical foundation for the development of multilayer composite nonwovens air filter materials with high filtering quality.
