Description 409-418
This study aims at providing a new approach to develop a rheological model predicting the stress relaxation behavior of
cotton-covered elastane core-spun yarns. The yarns have been manufactured with various counts and elastane drafts.
According to a yarn’s tensile and relaxation dataset, the model integrated three components characterizing different tensile
curves’ zones. The model validation is established for the whole yarn’s range. Besides, this model fitted well the
experimental data with a significant correlation coefficient. Also, it is important to highlight that most of the rheological
parameters have almost the same values for various elastane drafts, yarn counts, and imposed deformation levels. Those
reproducible results allow us to simulate the elastic core-spun yarn behavior under different constraints and to identify some
mechanical parameters relevant to simulate and predict the end product’s properties.
