摘要
为探索新的织物耐磨性测试方法,设计并制造出自制耐磨仪。介绍了自制耐磨仪的原理、结构以及测试方法。在一定充气压力下应用自制耐磨仪对织物折皱点进行摩擦,通过气流量的变化实时反映织物的磨损情况,通过伯努利方程将变化气流量转化为等效孔径,选取等效孔径值来评价织物折皱点的耐磨性能。采用正交试验,选取摩擦速度、充气压力、面料厚度3个测试参数,对羽绒面料折皱点的耐磨性能进行了测试,分析了它们对羽绒面料折皱点耐磨性能的影响。结果表明,自制耐磨仪在一定条件下,可表征羽绒面料折皱点的耐磨性能。充气压力和面料厚度对羽绒面料折皱点的耐磨性能有显著影响,摩擦速度对其影响不显著,充气压力的影响最为显著。研究结果为改善羽绒服面料折皱点的耐磨性提供了借鉴方法。
In order to explore a new method for testing the fabric abrasion resistance, a homemade abrasion tester is designed and manufactured. The principle, structure and test method of the homemade abrasion tester are introduced. The crease points on fabrics are rubbed using the abrasion tester under certain air pressure and the abrasion of fabrics is reflected on real time through the change of gas flow. The change of gas flow is converted into equivalent aperture by Bernoulli equation and the equivalent aperture is used to evaluate the abrasion resistance of the crease point on fabric. Three measuring parameters of friction velocity, gas pressure and fabric thickness influencing on the abrasion resistance of crease point on down fabrics are tested by orthogonal experiment. The influence of the three elements on the abrasion resistance is analyzed. The results show that the homemade abrasion tester can represent the abrasion resistance of crease point under certain conditions. The gas pressure and fabric thickness have significant influence on the abrasion resistance, but the influence of friction velocity is not significant. Above all, the gas pressure has the most high influence. The research result prevides reference for improving the abrasion resistance of crease points on down fabrics.
