模拟实际着装的织物抗皱性测试方法

针对现有的织物抗皱性测试方法不能直接用来表征穿着过程引起的折皱这一现象，提出一种可模拟实际着装的织物抗皱性测试方法。构建了模拟装置，并利用图像处理技术提取了折皱密度。经20块织物的相关实验验证得出：模拟方法与实际着装产生的折皱非常相似，说明模拟方法具有一定的可行性，且其测试稳定性好于折皱回复角法；0°折皱回复角与折皱密度的相关性最大，随后是45°，建议增加45°折皱回复角的测试，以使测试结果更能表征实际着装时织物的折皱变形能力；建立了多元回归模型，此模型可用来预测实际着装时的折皱密度，无需经过工作量繁重的服装制作和实际穿着实验。

Measurement for fabric wrinkle resistance by simulating actual wear

The available fabric wrinkling measurements could not be used to characterize the wrinkling behavior during actual wearing.Aiming at this,a simple method for fabric wrinkling measurement that can simulate actual wear was put forward.A simulating device was set up and image processing technology was used to extract wrinkle density.Experiment was conducted with 20 fabrics.The following conclusions can be drawn.Wrinkles produced by the simulating method are very similar with those in actual wear,which proves the feasibility of the method.Besides,its measuring stability is better than that of the wrinkle recovery angle method.Wrinkle recovery angle in 0° has the highest correlation with wrinkle density,after which is 45°.It is advisable that wrinkle recovery angle in 45° should be considered to improve the agreement of the testing results and the actual wrinkling capability during wear.Models between wrinkle density and wrinkle recovery angle established by multiple linear regression can be used to predict fabric wrinkling during actual wear,without need of the tedious clothes making and trial work.
