摘要
针对现有织物弯曲性测试需要用多块试样才能得到多个测试结果的现状,提出一种既简便又节约面料的预测毛织物弯曲性的方法蝴蝶结法。详细阐述了用蝴蝶结法测试织物弯曲性的实施步骤及采用的表征参数:蝴蝶结面积、宽度、高度和角度。以18块毛织物为研究对象,用新方法与传统方法进行对比测试分析。结果表明:新方法中的4个参数与毛织物的抗弯刚度都具有较好的相关性,且越硬挺的毛织物形成的蝴蝶结角度、宽度和面积越大,高度越小,其中蝴蝶结面积与抗弯刚度的相关性最高;用蝴蝶结法建立的蝴蝶结面积与织物抗弯刚度的关系式可预测毛织物的抗弯刚度。
Aiming at the actuality that for the measurement of the fabric bending behavior, more than one fabric samples are needed to obtain more than one test result, a simple and fabric saving bowknot method for testing the bending behavior of wool fabric was proposed, and the detailed method and parameters of area, width, height and angle of bowknot were elaborated. 18 kinds of wool fabrics were used to compare the new method with the conventional method. The results show that the correlations between the four indexes in the new method and bending rigidity are good. The bowknots of stiffer wool fabrics will have larger angle, width and area, but smaller height. The area of the bowknot has the highest correlation with the bending rigidity. Moreover, the regression equation between the area bowknot and the bending rigidity is established for the predicting the fabric bending rigidity.
