Vinyl chloride/vinyl acetate/ethylene/self-crosslinking polymers for non-cellulosic based substrates

摘要

The invention relates to an improvement in adhesive polymeric binders for nonwoven products and to the nonwoven product. The basic polymeric binder is comprised of emulsion polymerized units of vinyl acetate, ethylene and self-crosslinking monomer(s), e.g., N-methylol acrylamide. The improvement in the adhesive polymeric binder for forming nonwoven webs comprised largely of synthetic fibers resides in the presence of vinyl chloride polymerized into the vinyl acetate/ethylene polymer backbone.
