Composite abrasive filaments, methods of making same, articles incorporating same, and methods of using said articles

A composite abrasive filament comprising at least one preformed core at least partially coated with a hardened composition comprising a thermoplastic elastomer and abrasive particles, said abrasive particles dispersed and adhered in the thermoplastic elastomer, said abrasive particles present in said hardened composition at a weight percent ranging from about 0.1 to about 65 weight percent, and said preformed core consisting of a plied yarn of fibers selected from the group consisting of glass fibers, ceramic fibers, natural fibers, organic synthetic fibers, inorganic synthetic fibers, and combinations thereof.

A composite abrasive filament comprising at least one preformed core at least partially coated with a hardened composition comprising a segmented thermoplastic elastomer and abrasive particles, said abrasive particles dispersed and adhered in the segmented thermoplastic elastomer, said abrasive particles present in said hardened composition at a weight percent ranging from about 0.1 to about 65 weight percent, and said segmented thermoplastic elastomer having a Shore D durometer hardness ranging from about 30 to about 90.
