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

This study focuses on the theoretical and experimental creep behavior of plain woven fabrics using the yarn creep property and the structural—mechanical parameters of the fabric. For this purpose, two viscoelastic models, i.e. the Kelvin model in series with a spring and the Eyring model, were developed as a theoretical analysis to predict the fabric elongation while subjected to a constant load. Then, the theoretical results from these models were compared with experimental results for fabrics of different weft densities. It was obtained that the later model shows closer results to the experimental creep than earlier model. It was also found that an increase in weft density leads to a decrease in fabric creep.
