Test and Research to the Dank Ratio of Woven Filtering Fabric
No matter for clothes fabric or industry fabric, the water permeability is an important performance indicator. In order to explore relationship of the water permeability of woven filtering fabrics with the fabric structure parameters, we design sixteen fabric. According to the national standards of determination of water permeability of woven filtering fabric, we test the dank ratio of the design fabric. In this paper we analysis the water permeability and structure parameter of woven filtering fabric with test the quality of water on some time through woven fabrics. We calculated the dank ratio from the water permeable quality and other parameters. The results indicate that, the effect of fabric texture on the dank ratio of woven fabrics is that the dank ratio of the plain weave is the smallest and the satin weave is the biggest. In addition, the relationship between overall covering factor and water permeability showed that the water permeability decreases along with the overall covering factor increasing. A linear regression equation between dank ratio and overall covering factor is get from the test results. In order to get big dank ratio, we should produce fabric with satin weave and lower overall covering factor.
