Abstract:

The tensile properties of polyurethane filaments, Modal yarns and Modal/polyurethane core-spun yarns were tested. The stress-strain relationship of the yarns is analysed using a nonlinear viscoelastic model, and the multinomial relationship between stress and strain is obtained. Curve fitting is also made using the least square method. Theoretical calculations agree with the measured results very well.
