ABSTRACT:
A nonwoven abrasive or scouring article having at least one major surface and an interior region comprises an open, lofty web of first and second crimped, staple organic thermoplastic fibers, wherein the first organic thermoplastic fiber comprises materials selected from the group consisting of polyamides, pololefins, and polyesters, and wherein said second organic thermoplastic fiber comprises at least two materials of different heat stability. The first and second organic crimped, staple thermoplastic fibers are melt-bonded together at least at a portion of points where they contact. At least a portion of the first and second fibers of one major surface of the nonwoven article have an abrasive coating bonded thereto, and at least a portion of the first and second fibers of the interior region have no abrasive coating bonded thereto, a structure which minimizes the amount of binder which must be used.
