Prediction of Fabric porosity from Yarn Diameter and effect of different spinning techniques and process on porosity

Abstract

Along many other factors, fabric comfort depends upon the fabric cover factor and porosity. This research work is based on the prediction of fabric porosity by measuring diameters (by empirical formula) of different yarns and put them in an equation for porosity measurement. This will be helpful to predict the porosity of different fabric structures by knowing the yarn diameter only. Effect of different yarn diameters on porosity produced by various spinning techniques (ring, compact) and processes (carded, combed) is also the part of study. At the end, comparison between the relationships of yarn diameter, spinning process and techniques and fabric porosity is shown graphically. This research work is helpful regarding the comfort properties of fabric.
