Abstract:

An abrasive pad, especially useful in cleaning and scouring kitchen utensils, is comprised of a lofty fibrous nonwoven structure of mixed denier nylon or polyester crimped filaments bonded at contacting points with thermosetting resin containing finely divided soft abrasive and coated on one of its surfaces with thermosetting resin containing finely divided hard abrasive. The pad surface containing soft abrasive provides a mildly abrasive surface capable of cleaning, without harmfully scratching, non-stick plastic pan coatings (e. g. , "Teflon" perfluoroethylene polymer), plastic dishes, etc. The pad surface containing the hard abrasive provides an aggressive abrasive surface capable of scouring stainless steel or aluminum pots and pans soiled with baked-on or burned cooking residues.
