摘　　要：为探究较精确、易行的测试和表征织物折皱回复角的方法,首先采用KES-F织物风格仪测试了织物的弯曲、剪切、拉伸和压缩性能,并在KES系统原有力学性能指标基础上引入2个新指标:残余弯曲曲率和残余剪切变形,进而通过数据分析建立了采用织物力学性能指标表示其经、纬向折皱回复角的回归方程;同时分析了织物折皱回复角与各力学性能指标间的相关性。结果表明:回归方程的计算值与折皱回复角的实测值差异不超过0.1°;拉伸功回复率、拉伸比功和弯曲刚度对织物折皱回复性的影响最大,可以通过提高织物的抗拉伸、弯曲和剪切性能及拉伸功回复率来改善织物的抗皱性。To explore a more accurate and easy method for testing and characterization fabric＇s wrinkle recovery angle, the bending, shear, tensile and compression properties of fabrics were tested by KES-FB- AUTO-A system tester, and two new parameters： residual bending curvature and residual shear deformation, were introduced based on the original mechanical parameters of KES system tester. Through data analysis, regression equations by which warp and weft wrinkle recovery angles were calculated using mechanical parameters were established, respectively. The relationship between fabric＇s wrinkle recovery angle and mechanical parameters was analyzed. The results indicated that the difference between the calculated value of wrinkle recovery angle by regression equation and the tested value did not exceed 0.1°; and the drawing work recovery percentage, draw ratio work and bending stiffness had the greatest impact on the crease recovery, and hence fabric＇s wrinkle resistance can be enhanced by improving its stretch resistance, bending resistance, shearing strength and drawing work recovery oercentaze.
