摘要/Abstract

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两个新指标，残余弯曲曲率K和残余剪切变形Φ，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。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°。为了进一步把握并改善织物的折皱性，分析了织物折皱回复角与各力学性能指标间的相关性，发现拉伸功回复率、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、弯曲和剪切性能及织物的拉伸回复率来改善织物的抗皱性。

Abstract: To explore more accurate and easy testing and characterization method for fabric’s wrinkle recovery angle, bending, shear, tensile and compression properties of fabrics were tested by KES-FB-AUTO-A System Tester, and two new parameters: residual bending curvature K and residual shear deformationφ, were introduced basing on the original mechanical parameters of KES System Tester. Furthermore, regression equations that warp and weft wrinkle recovery angles were calculated by mechanical parameters were established, respectively. The results indicated that the difference between calculated and tested values of crease recovery angles did not exceed 0.1°. In order to further understand and improve the creasability of fabrics, relationship between fabric’s wrinkle recovery angle and mechanical parameters was analyzed. It was found that tensile recovery percentage, tensile power and bending stiffness had the greatest impact on crease recovery, and fabric anti-crease could be improved by improving stretch resistance, bending resistance, shearing strength and tensile recovery percentage.

Key words: fabric, wrinkle recovery angle, mechanical property, regression equation, relationship
