  • Low temperature curing of nonwoven products bonded with N-methylolacrylamide-containing copolymers
    Patent number: 4590102
    Abstract: A nonwoven substrate impregnated with a vinyl acetate/ethylene/N-methylolacrylamide or vinyl chloride/ethylene/N-methylolacrylamide copolymer emulsion binder is cured by employing an acidic substance having a pKa of 1 to 2, sufficiently drying to volatilize a substantial amount of the water while not substantially cross-linking the copolymer binder and maintaining the dried nonwoven substrate at a temperature less than that for drying for a time sufficient to develop essentially full cure.
