基于图像处理的织物多方向抗皱性测试方法

Fabric multi-directional wrinkle resistance testing based on image processing

目前的抗皱性测试方法只能测试织物单一方向的折皱回复性,这与实际穿着时织物多方向的起皱形态相差较大。针对这种情况,首先设计一种能近似模拟服装膝盖和肘部起皱形态的多方向起皱装置,然后给出使用此装置进行测试的方法,并提出2个评价指标:急弹性和缓弹性抗皱面积比,最后将20块织物的这2个指标与急弹性和缓弹性折皱回复角进行对比分析,得出急弹性和缓弹性抗皱面积比分别与急弹性和缓弹性折皱回复角具有高度正相关关系。多方向起皱装置所形成的折皱形态更接近服装实际穿着时的起皱形态,也能更好地反映织物的综合抗皱能力。

The existing commonly used testing method can only test one directional wrinkle recovery,which differs greatly from the wrinkle state of the garment during wearing.Aiming at this,firstly a new fabric multi-directional wrinkle resistance testing device was designed which can simulate the wrinkles on the knee and elbow.And then the testing process was given,as well as two evaluation indexes and wrinkle resistance area ratio between acute elastic recovery and slow elastic recovery.Finally,the two indexes were compared with the acute elastic recovery angle,and slow elastic recovery angle of 20 pieces of fabric.It was found that the wrinkle resistance area ratio between the acute and slow elastic recovery was closely correlated with the acute elastic recovery angle and slow elastic recovery angle,respectively.As the wrinkle state formed on the new testing instrument is more similar to that on the garment during wearing,the new method can better reflect the comprehensive wrinkle resistance of fabrics.
