Vinyl acetate/ethylene and vinyl chloride polymer blends as binders for nonwoven products

摘要

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.
