An open low density abrasive article adapted for the cleaning of aluminum or similar surfaces comprising a lofty open non-woven three dimensional web form of a plurality of interlaced randomly extending flexible durable, tough, resilient organic fibers said web fibers being firmly adhesively bonded
An open low density abrasive article adapted for the cleaning of aluminum or similar surfaces comprising a lofty open non-woven three dimensional web form of a plurality of interlaced randomly extending flexible durable, tough, resilient organic fibers said web fibers being firmly adhesively bonded together at points where they cross and contact each other to form a three-dimensionally integrated structure throughout said web, and abrasive particles distributed within said web and firmly bonded to the web fibers by a relatively hard binder, the interstices between adjacent fibers being open and substantially unfilled by binder or abrasive, there being defined throughout said aricle a tridimensionally extending network of intercommunicating voids constituting the major portion of the volume of the said article, said article being flexible and readily compressible and, upon release of pressure capable of recovering substantially completely to its initial form, wherein said abrasive is defined by any one of the measures of hardness selected from the group of measures consisting of a) Mho\s 4.5-6.3, b) Rockwell B60-85, c) Brinell 95-142, d) Knoopp 120-180. In certain embodiments, the abrasive layer may be associated with sponge-like material and/or a cleansing or lubricating agent suitably a soap.

An open low density abrasive article adapted for the cleaning of moderately soft metallic surfaces comprising: a substrate selected from the group consisting of i) a lofty open non-woven three dimensional web form substrate of a plurality of interlaced randomly extending flexible durable, tough, resilient organic fibers having a diameter of from about 25 to about 250 microns, said web fibers being firmly adhesively bonded together at points where they cross and contact each other to form a three-dimensionally integrated structure throughout said web, there being defined throughout said article a tridimensionally extending network of intercommunicating voids constituting the major portion of the volume of the said article, said article being flexible and readily compressible and, upon release of pressure capable of recovering substantially completely to its initial form, the interstices between adjacent fibers being open and substantially unfilled by binder or abrasive, ii) a polymeric flexible foam selected from the group consisting of urethane, polypropylene, polyethylene, polyvinyl alcohol, silicone rubber, neoprene and natural rubber latex of density between about 0.015 g/cm3 and about 0.1 g/cm3, iii) woven fabrics of natural and synthetic fibers selected from the group consisting of terry, duck, twill, oznaberg, and leno of surface density between about 100 g/m2 and about 410 g/m2, iv) non-woven fabrics of natural and synthetic fibers selected from the group consisting of spunbonded, fibre entangled, thermal and chemical bonded and needle punched of surface density between about 75 g/m2 and about 285 g/m2 and v) high wet strength, substantially water resistant papers of the kraft or zinc chloride treated type of surface density from about 100 g/m2 to about 1 kg/m2, and abrasive particles distributed upon and within said substrate and firmly bonded to the substrate fibers by a relatively hard binder, wherein said abrasive is defined by any one of the measures of hardness selected from the group of measures consisting of: ________________________________ -a) Mho\s 4.5-6.3 b) Rockwell B 60-85 c) Brinell 95-142 d) Knoop 120-180 ________________________________ wherein the abrasive material is selected from the group consisting of finely divided copper base alloy, iron, nickel base alloy, spherical glass beads, steel or mineral.
