Abstract: | Hollow/microporous yarn spinning is a technique used to increase the bulk of yarn without increasing its weight. Hollowness in the cotton yarns has been introduced by various methods and techniques. Empirical models have been developed to predict the thermophysiological properties through structural parameters. Based on standardized multiple linear regression models, fabric’s structural parameters are related with thermophysiological properties of hollow yarn fabrics. Three basic parameters i.e. yarns packing density, inter-yarn porosity and fabric thickness have been found to relate strongly with fabric thermophysiological properties except water vapour permeability. |
