This invention is directed to an improvement in binders particularly
suited for use in preparing nonwoven products and to the nonwoven
products. The improved binders comprise a blend of emulsion polymerized
ethylene-vinyl chloride (EVCl) polymer and an emulsion polymerized self
crosslinkable vinyl acetate-ethylene-N-methylolacrylamide (VAE-NMA)
polymer. The blends of the EVCl polymer emulsion and the VAE-NMA polymer
emulsion can be applied to cellulose and cellulose/synthetic nonwoven
substrates and cured in the absence of an acid catalyst to provide a
self-sustaining web having excellent wet strength performance. The blends
of EVCl and VAE-NMA polymers do not require an acid catalyst to
facilitate cure.
