A Novel Instrument for Testing the Frictional Properties of Fabric Surfaces
Tanyu Wang,Zhaoguang Zuo,Jun Xie,Jinliang Chen,Hao Liu,Sha Li 한국섬유공학회 2022 Fibers and polymers Vol.23 No.8
The surface structure of a fabric not only affects the style, appearance and weaving process of the fabric, but alsohas an important influence on the performance and comfort of the garment it is processed on. The surface friction propertiesof fabrics are one of the important mechanical characteristics in the evaluation of fabric feel and can provide an importantscientific basis for the performance evaluation and quality control of fabrics. The system consists of a test module and acontrol module, which can dynamically test the changes in positive pressure and multiple directions in real time. The testprocess is controlled in real time by the measurement and control software in the control module, which also displays thenumerical magnitude and variation curves of the friction coefficient, positive pressure and friction force. The coefficient ofvariation (CV) of the coefficient of friction for fabrics with different test speeds at the same time is less than 10 % for normalexperiments on fabrics. After five repeatable tests using cotton, polyester-cotton and polyester fabrics, the mean values of thecoefficient of friction for the three fabrics were very close and the instrument showed good stability and repeatability. Incomparison tests with the KES fabric style meter test system, the coefficient of friction curves for cotton fabrics measured byboth instruments were consistent, with the mean values fluctuating slightly around 0.23. After five tests, the inter-group CVof the surface friction coefficient of the fabric was only 0.88 %. A correlation analysis of the surface roughness of the fabricusing the data processing method and the roughness signal obtained from the KES direct test showed a correlation coefficientgreater than 0.8 and a slope of the linear regression line greater than 1, demonstrating the high correlation between theindirect test method using data processing and the direct test of the mechanical test.
