Modeling the Fatigue Behavior of Plain Woven Fabrics Constructed from Textured Polyester Yarn

This study focused on the prediction of fatigue behavior of plain woven fabrics using the yarn fatigue property and the structural-mechanical parameters of the fabric. For this purpose, the Eyring viscoelastic model was developed as a theoretical analysis to predict the fabric elongation while subjected to a constant cyclic load. It was suggested that the elongation of the fabric under constant cyclic load consists of three parts: fabric decrimping arising from yarn slippage in the fabric, yarn decrimping, and finally yarn elongation. Comparison between the theoretical and experimental results for different weave densities of fabric revealed a reasonable agreement between them. It was concluded that an increase in weave density leads to decrease in fabric fatigue.
