Abstract
Friction measurem ent is one of the important and interesting problems in the study of handle properties of fabrics. Different methods have been developed for measuring friction, such as sliding, Kawabata Evaluation System (KES) and cyclic testing. In this research, considering the possibilities of varying conditions in measuring friction, a new instrument is used in which the bottom surface of fabric can be moved and the top slider is kept fixed in order to prevent slider vibrations. In this method, the force inserted by an extensible yarn connected to the trolley standing on four very smooth bearings was measured. The result of experiments confirmed 7.6% increase in correlation coefficient in the dynamic friction region for nine different test samples and about 4.6% reduction in coefficient of variation compared to the sliding type.
