2124833 9318891 PCTABS00025 An abrasive filament, including a thermoplastic elastomer having abrasive particles dispersed and adhered therein, exhibits improved life over previously known abrasive-filled polymeric filaments. Previously known abrasive-filled nylon filaments have limited stiffness and lose their stiffness as temperatures approach 70 ·C. The abrasive filaments of the present invention are more efficient and more resistant to flex fatigue failure than abrasive-filled nylon filaments. Methods of making abrasive filaments of the invention, articles including the abrasive filaments, and methods of abrading surfaces using the abrasive articles of the invention are also described.
