An Investigation of the Creep Behavior of Plain Woven Fabrics

An Investigation of the Creep Behavior of Plain Woven Fabrics
 Azita Asayesh1, Ali A.A. Jeddi

Abstract
 Two theoretical models for predicting the creep behavior of plain woven fabrics based on viscoelastic models andusing the creep behavior of constituent yarns and the structural- mechanical parameters of the fabric have been proposed. For this purpose, the Kelvin model in series with spring and the Eyring model were considered as viscoelastic models. These theoretical models reveal that the elongation of the fabric with time when is subjected to a constant load, consists of three stages; Fabric elongation arising from yarn decrimping inside the fabric, yarn decrimping (The crimp caused by yarn texturing), and finally yarn elongation. Comparison between the theoretical results from these models and experimental results for fabrics of different weft densities represent that the Eyring model predict the creep behavior of the fabrics better than the Kelvin model in series with spring. It was also found that an increase in weft density leads to decrease in fabric creep.
Keywords: Yarn creep, Woven fabric, Kelvin model in series with spring, Eyring model, Weave density.
