Abstract:
An abrasive filament, a cloth or non-woven made of the filament and an abrasive device, e.g., sanding disk, incorporating the fabric, cloth or non-woven and methods of producing the same are disclosed. The filament has an outer surface to which plural small size particles of an abrasive material are secured. The filament is formed from a mass of a molten polymer material, e.g., nylon, that has been extruded through a small diameter opening to form a hot elongated filamentary body. The abrasive particles, e.g., grit, are applied as a cloud or spray to the outer surface of the hot elongated filamentary body, whereupon they adhere to that surface and remain permanently secured thereto.
