Prediction of the in-plane and through-plane fluid flow behavior of woven fabrics

The permeability property of fabric is a desired performance property of textile structure used in different areas. In this study, the relationship between in-plane and through-plane permeability behaviors and the structural properties of woven fabrics having numerous usage areas, such as clothing and technical textiles, were investigated with the help of data obtained from a group of test fabrics having different weave types and weft settings, which were produced by using the same warp and weft linear density. In the study, the pore properties were examined in two regions: inter-yarn and inter-fiber pore regions. After defining the pore properties, which were determined by the structural and geometrical properties of fabric according to different approaches, the permeability results of both in-plane and through-plane directions were predicted theoretically by using obtained pore properties in flow equations. Estimated permeability results were compared with experimental results and the suitability of methods were discussed
