织物折皱回复角与其物理力学性能的关系

Relationship between fabric′s wrinkle recovery angle and its physical and mechanical property

针对当前织物抗皱性能的重要评价指标折皱回复角的检测存在工作量大,测量精度低,测试数据不稳定等问题,运用KES-F风格仪测量织物的弯曲刚度、弯曲滞后矩、拉伸功和织物厚度等物理力学参数,运用SDL-M003A折皱回复角试验机按AATCC 66—2003测得织物的折皱回复角,在此基础上,建立织物的折皱回复角与织物物理力学参数之间的线性回归方程。从折皱回复角计算值和实测值的检验结果看,二者的绝对误差小于3°,相对误差小于5%,表明得出的回归方程有较高的应用价值。

Wrinkle recovery angle is the most important evaluating indicator of fabric＇s anti-wrlnkle performance. But many problems such as heavy workload, low measurement accuracy and unstable measurement data are associated with the wrinkle recovery angle measurement. In this paper, the physical and mechanical parameters such as bending rigidity, bending hysteresis moment, tension work and thickness of fabric are measured with KES-F instruments, and the wrinkle recovery angle is measured with SDL-MOO3A according to the standard AATCC 66-2003. On this basis, linear regression equation with physical and mechanical parameters and wrinkle recovery angle is established. The checking results between actual measuring value and calculating value show that the absolute error is smaller than 3° and the relatively error is less than 5 %, which indicate the regression equation has better application value.
