Homemade abrasion tester and its application for abrasion resistance testing of crease points on down fabrics

Abstract

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.
