On the Poissonʹs ratios of a woven fabric

Although it is undeniable that the Poissonʹs effect on the behavior of a woven fabric is crucial, there have been relatively few papers devoted to this subject. In this study, a mechanical model for a woven fabric made of extensible yarns is developed to calculate the fabric Poissonʹs ratios. Theoretical results are compared with the available experimental data. A thorough examination on the influences of various mechanical properties of yarns and structural parameters of fabrics on the Poissonʹs ratios of a woven fabric is given. The prediction of Poissonʹs ratios in this paper will enable more rigorous studies on such important issues of fabric bending and draping behaviors.
