为从织物自身组织结构方面优化纯棉织物的折皱性,首先设计织物组织结构参数并制备织物,利用数字式织物折皱弹性仪测得织物的折皱回复角.在此基础上,建立纯棉织物经、纬向和总折皱回复角与织物组织结构参数(包括经纬纱线密度、经纬纱捻度、经纬向密度)之间的线性回归方程;同时分析织物折皱回复角与各组织结构参数间的相关性.结果表明:回归方程的计算值与折皱回复角实测值绝对误差不超过0.61°,回归方程具有较高的实用性;经纬纱捻度、线密度对纯棉织物的折皱回复性影响最大,可通过提高经纬纱捻度、降低经纬纱线密度来改善纯棉织物的抗皱性.%In order to optimize the crease property of pure cotton fabric from its weave structure,firstly,fabric's weave structure parameters were designed and fabrics were woven,then the winkle recovery angles were measured by digital wrinkle-recovery tester.On this basis,the linear regression equations among the fabric's warp,weft and total wrinkle recovery angles and weave structure parameters were established,which included warp and weft yarn linear density,warp and weft yarn twist,warp density and weft density.The relationship between fabric's wrinkle recovery angle and weave structure parameters was analyzed.The results indicate that the absolute error of the regression equation between calculated values and measured values about wrinkle recovery angle is smaller than 0.61°,and the regression equation has higher practicability.Warp and weft yarn twist,warp and weft yarn linear density have the greatest impact on fabric's crease recovery,and hence the fabric's crease resistance can be improved by increasing the yarn twist and reducing the yarn linear density.
