摘要: 对氨纶弹力丝、Modal纱和Modal包芯纱的力学性能进行了测试 ,利用非线性弹簧和标准线性固体模型并联组成的模型对其应力应变关系进行了分析 ,并用多项式对其应力应变关系进行了拟合 ,结果表明 ,理论和实测结果相符合。

Abstract: The tensile properties of polyurethane filaments, Modal yarns and Modal/polyurethane core spun yarns were tested. The stress strain relationship of the yarns was analyzed using a nonlinear viscoelastic model. And a multinomial relationship between stress and strain was obtained.The stress_strain curves were fitted using least square method. The results show that the theoretical calculations agree well with the measured results very well.
