Abstract: Wrinkle recovery angle is the most important evaluating indicator of fabric′s anti-wrinkle 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-M003A 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.
