1. An abrasive article comprised of at least one elongate abrasive filament, each elongate abrasive filament having a first end and a second end, each first end attached to a substrate, wherein at least a portion of said elongate abrasive filaments comprise:
- (a) a first elongate filament component having a continuous surface throughout its length and being comprised of a first hardened organic polymeric material; and
(b) a second elongate filament component coterminous with said first elongate filament component comprised of a second hardened organic polymeric material in melt fusion adherent contact with said first elongate filament component along said continuous surface, the second hardened organic polymeric material being the same or different than the first hardened organic polymeric material,wherein at least one of the first and second hardened organic polymeric materials comprises a first thermoplastic elastomer, the first thermoplastic elastomer having abrasive particles dispersed and adhered therein.
