Abstract

Nanofiber has shown outstanding performance in many studies. Blending nanofibers into fibrous filter media is a promising way to improve the filtration performance. This paper discussed the modeling method for multi-fiber filter paper and the proper way to apply nanofiber into filter paper. Sixteen different filter papers were prepared and these filter papers covered the range of coarse-fiber-dominant and fine-fiber-dominant fibrous structure. The theoretical modeling method in this study for pressure drop and penetration of multi-fiber filter paper showed accurate results compared with the experiment data. It was found that for the higher quality factor, the nanofibers should be effectively separated by the coarse fibers. This study presented the idea of the fiber's effective contribution to filtration efficiency, which can lead to a comprehensive and distinct understanding of fibrous structure and filtration properties.
