Abstract
A process for forming a synthetic based nonwoven web bonded with a crosslinkable polymer wherein an aqueous polymeric emulsion containing a crosslinkable polymer is applied to the synthetic based nonwoven web, the water removed, and the crosslinkable polymer crosslinked. The crosslinkable polymer incorporates acetoacetate functionality and carboxylic acid functionality; wherein crosslinking is achieved by the reaction of the acetoacetate with an effective amount of a polyaldehyde and the reaction of the carboxylic acid with an effective amount of a polyaziridine compound.
