فایل Prediction of the Permeability of Woven Fabrics

In this study, the Hagen–Poiseuille formula has been used to establishthe equation expressing the relationship between permeability of interyarn intersticesand fabric structures. Validation with experimental data shows that interyarnporosity has a very strong influence on fabric permeability. The stepwise regressionmethod has been used to explore the permeability of interfiber interstices.The prediction equation has been developed focusing on the permeability of interyarnpores and the overall fabric cover factor. One set of worsted fabrics is used tovalidate the equation. It shows that except for fabrics with z/z twist yarns or twistlessfilaments, the predicted equation gives a good accuracy with an average error of
13%.
