The abrasion characteristics of low‐twist polypropylene multi‐filament yarns free of surface lubricants were determined by rubbing the yarns against each other by using a reciprocating action device at a frequency of 60 cycles/min. It was found that the abrasion behavior of the yarns varies over a wide range and is related to such fundamental properties as the polymer and fiber molecular weight, undrawn fiber orientation and crystalline structure, drawn fiber properties, and elevated temperature post‐treatment. It was also found that presence of surface lubricants could increase the number of abrasion cycles to failure by as much as a factor of 20, depending upon the particular lubricant employed. The mechanism of the process of fiber failure resulting from abrasion damage was examined and appears to be one in which the fiber rupture is preceded by a tearing and peeling back of fiber surface fragements probably initiated at flaws in the fiber surface.
