Experimental Study on Micropore Structure and Filtration Characteristics of Polypropylene Melt-Blown Nonwoven

Abstract:

Melt-blown nonwoven fabric is a kind of excellent fiber filter media in the field of air filtration, which has the characteristics of high specific surface area, small pore size, high porosity, superfine fiber, low pressure drop and high filtration efficiency. In this paper, the microstructure characteristics of pore diameter and pore size distribution of polypropylene melt-blown nonwoven, and the relationship of micropore structure and filtration characteristics, continuous dust holding test were studies by using instruments of Microscope, Capillary Flow Porometer and TSI 8130 Auto Filter Tester.
