摘要
针对织物的各向异性,研究了纯棉平纹和斜纹织物的折皱回复性能随取向角变化的情况。采用织物折皱回复动态测试仪测量不同取向角的动态回复指标,包括初始回复速率、急弹时间、急弹回复角度、缓弹时间、缓弹回复角度。结果表明,仅回复角度随取向角变化存在一定规律性,平纹织物的折皱回复角度随着取向角的增加呈现先增大后减小的趋势,斜纹织物正面对折和反面对折试样的趋势有所不同。试验证明了织物对角线方向能较全面反映结构均匀平纹织物的折皱回复性能,斜纹斜向和其垂直方向能作为斜纹织物的测试角度。
Aiming at the anisotropy of woven fabric, the changes of the crease recovery properties of 100% plain and twill fabrics with the orientation angle are explored in this research. The recovery parameters, such as initial recovery rate, instant recovery time, instant recovery angle, stable recovery time and stable recovery angle, were obtained by a dynamic crease recovery tester. The test results illustrate that only the recovery angles changes with the orientation angle. The trend of plain fabric shows that its recovery angle generally increases at first and then decreases with the increase of the orientation angle. The trend of twill fabric differs from folding ways. It is proved that the diagonal direction is the optimal orientation angle for a balanced plain fabric, while the two orthogonal directions, the twill direction and its perpendicular direction, were found to be more reasonable for testing a twill fabric.
