Abstract : An improved method of evaluating in the laboratory the simulated wear resistance of both monofilaments and staple yarns is described. Wear resistance is measured as a fraction of strength retained after abrasion against a solid PBI bar. The coefficients of variation in wear resistance findings are shown to be compatible with the coefficients of variation in tensile strength data of unabraded control specimens. (Author-PL)
