Experimental evaluation of the main parameters influencing friction between polyamide fibers and influence of friction on the abrasion resistance

Friction is one of the key factors in manufacture ropes, and has an important influence on mechanical behavior many fiber assemblies. For this reason, understanding evaluation coefficients friction between fibers essential step development numerical rope models. This paper describes tests a modified, upscaled version ASTM (American Society for Testing Materials) standard yarn-on-yarn abrasion test device, which allows measurement coefficient polyamide yarns. It shown that inter-fiber angle significant coefficient, direction movement relative to filament be considered determination coefficient. A normalized representation measured range conditions plotted single curve. The device throughout tests. concluded lower leads higher resistance longer lifetime.
