基于质量损失率和摩擦次数的灯芯绒棉机织物折边磨测试机理分析

Analysis to the test mechanism of corduroy cotton machine fabric flanging based on mass loss rate and friction number

为探讨灯芯绒棉织物的折边磨性能,分析了灯芯绒面料折边磨的测试影响因素、采用正交试验设计方法研究折叠方向、施加载荷、摩擦速率、摩擦介质、织物摩擦面这5个测试参数对灯芯绒棉织物的折边磨影响,并利用微观图像处理和计算质量损失率的方法对布面磨损情况进行测试与分析。结果表明:5个测试参数对面料折边磨损的影响具有统计学意义,且折叠方向斜45°、施加载荷为500 cN、转动速率为60 r/min、摩擦介质为砂轮时,灯芯绒棉织物折边磨检测时的质量损耗最大。

In order to investigate the performance of corduroy cotton fabric flanging,the influence factors of corduroy fabric flanging test were analyzed,and the influence of 5 test parameters such as folding direction,applied load,friction rate,friction medium and fabric friction surface on the flanging of corduroy cotton fabric was studied by orthogonal test method.The wear condition of cloth surface is tested and analyzed by means of micro image processing and mass loss ratio calculation.The results show that the influence of 5 test parameters on fabric hem wear is statistically significant,and when the folding direction is inclined to 45°,the load is 500 cN,the rotation rate is 60 r/min,and the friction medium is grinding wheel,the mass loss of corduroy cotton fabric hem grinding is the largest.
