摘要
选择纯棉、涤纶和羊毛3种类型的机织物,利用自制马鞍状织物弯曲装置进行反复弯曲性能测试。结果显示:机织物的1次弯曲曲线和10次反复弯曲曲线之间有较大的差距,多次弯曲能更准确的反映织物的弯曲性能。根据Ghosh的四次多项式织物的弯曲理论,得到6种试样的经、纬向1次和10次弯曲过程的拟合方程,并提出了多次弯曲功差异率、多次弯曲回复功差异率和头末次滞后功差异率3项指标,用于比较机织物反复弯曲性能。通过对试样进行反复弯曲性能进行测试,验证了该3项指标符合织物实际弯曲性能的特点。
The repeated bending property of three kind of woven fabrics made with cotton, polyester and wool, were tested by using a saddle-shaped fabric bending device. The results showed that the difference between the first bending curve and the curves of 10 repeated bending is obvious, the repeated bending of the fabric can reflect the bending performance of the fabric more accurately. According to the bending theory of Ghosh's quantic polynomial fabric, the fitting equations of the warp and weft bending processes of 6 kinds of samples for 1 and 10 times were obtained. Three bending work rate differences, multiple bending work return difference and initial and final work difference were used to compare the repeated bending performance of the woven fabric. The bending properties of the woven fabrics were tested and the results showed that the 3 item indicators can reflect the actual characteristics of the fabric bending.
