In order to explore the filtration performance of woven filter cloth to provide a design basis for filter cloth, the relationship of water permeability of filter cloth and fabric structural parameters is analyzed and studied by measuring the mass of water through the filter cloth within a specified time. The results show that water permeability rate of filter cloth decreases with the increase of fabric tightness, and the two assume the exponential function relationship. The relationship between yarn twist and water permeability rate assumes the linear positive correlation. The increase of yarn twist makes water permeability rate of filter cloth increase. The effect of textile weave on water permeability of filter cloth is that the water permeability rate of plain weave is the smallest and that of twill weave is the biggest.
