<p>A low-density non woven abrasive article formed of a multiplicity of continuous, crimped, thermoplastic organic filaments having a portion of the filaments entangled with one another and having an organic thermoset binder which binds at least some of the filaments at points where they contact, performs well as a scouring article. The filaments of the article may further have abrasive particles adhesively bound thereto by the binder. The web of the low-density article is produced by entangling a plurality of substantially parallel, continuous, crimped, thermoplastic organic filaments, preferably by needlepunching, and coating the entangled web with a binder precursor solution or slurry.</p> |
