Volume porosity and permeability in double-layer woven fabrics

Clothing for garments is designed to meet both the safety and the comfort of human beings. Porosity is considered to be one of the basic features representing a textile structure. The properties of fabrics were analyzed by determining the efficiency of fabric porosity. The woven fabric multi-layer structure, the warp and weft densities, and the type of weave are factors of a woven fabric, which as porous material enables to transmit air, heat energy, and liquid perspiration. Several methods considering thread distributions have been developed to determine the woven fabric’s porosity. A mathematical model based on an ideal geometry of the porous structure of a multi-layer woven fabric has been developed.
