Abstract:
1. A nonwoven product comprising a nonwoven web of fibers to which is applied a non acid catalyzed binder to form a binder impregnated web, the non acid catalyzed binder comprised of an emulsion blend of a first polymer comprised of emulsion polymerized units of vinyl acetate, ethylene, and N-methylolacrylamide, and a second polymer comprised of emulsion polymerized units of vinyl chloride, ethylene and N-methylolacrylamide or acrylamide or both N-methylolacrylamide and acrylamide, wherein the binder impregnated web is dried sufficiently to bind the fibers together and for a self-sustaining web, and wherein the blend, based on 100 parts by dry weight of total polymer, comprises 2 to 70 parts of the second polymer, less than 10 parts of a third polymer, and the remaining parts consisting of the first polymer.
