Research on Relationship between Air Permeability and Structure Parameter of Basalt Woven Filter Fabric

Abstract

Testing the volume of air through Basalt woven filter fabric during a certain time, the relationship between air permeability and parameters of the fabric structure was analyzed. The results showed that the greater the yarn linear density, the smaller the air permeability of fabric. The air percolation rate of filter fabric decreased along with the weft density increasing. Comparing 2/2 twill fabric with weft backed weave, the air permeability of plain weave was minimum, 2/2 twill fabric was the second, weft-backed weave was the largest.
