倒Ω法测试织物弯曲性及悬垂性
|
摘要
织物悬垂性和弯曲性的测试是纺织品检测的重要内容,目前这2种性能是分开进行的。针对此现状,以13块常见织物为研究对象,分别测试其弯曲性和悬垂性指标——抗弯刚度和悬垂系数,然后用自行设计的倒Ω法进行测试,并利用图像处理软件提取了水滴高宽比和下垂纵横比等特征参数。经过相关分析得出以下结论:作为尝试提出的倒Ω法可同时用来检测织物弯曲性和悬垂性,所提取的指标与抗弯刚度和悬垂系数具有较好的相关性,相关系数由大到小依次是下垂纵横比、水滴高宽比和水滴面积;利用下垂纵横比与抗弯刚度及悬垂系数的关系式,可以预测织物的弯曲性及悬垂性。
Measurement of fabric draping and bending performance is an important content in textile testing area.Currently,measurement of draping performance and that of bending performance are conducted separately. In view of this,13 common fabrics were tested for the bending and draping performance respectively—flexural rigidity and drape coefficient,then test was carried out with self-designed inverse Ω method,and characteristics parameters such as depth-width ratio of waterdrop and aspect ratio of droop were are extracted with image processing software. Related analyses lead to the following conclusions: the inverse Ω method put forward in this study can be used to test both bending and draping performance of fabric,the extracted indexes are highly correlated to flexural rigidity and drape coefficient with correlation coefficients in an order from large to small of aspect ratio of droop,depth-width ratio of waterdrop,and waterdrop area; fabric bending and draping performance can be predicted with the equations of aspect ratio of droop,flexural rigidity and drape coefficient.
