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 a vinyl chloride (VCI) polymer emulsion and a self crosslinkable vinyl acetate-ethylene-N-methylolacrylamide (VAE-NMA) polymer emulsion. The blend of the VCI 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.
