Abstract
Air permeability measurements over the range of 0 to 95% relative humidity indicate that changes in fiber dimensions caused by moisture absorption lead to changes in fabric structural parameters such as thickness and porosity. This phenomenon, which was most noticeable in the more hygroscopic fabrics, was observed in both woven and nonwoven fabrics. Important variables include the fabric structure and intrafabric constraint factors, such as number of bonding points, yarn twist, and yarn cross-over points.Keywords
