Claim 2:
3. A process for preparing a nonwoven material comprising:
treating a nonwoven fibrous substrate comprising cellulosic fibers and synthetic fibers with a mixture of a polyvinylamine polymer and a poly(amideamine-epichlorohydrin) polymer, to form a cross-linked polymeric network consisting of the polyvinylamine polymer and the poly(amideamine-epichlorohydrin) polymer that encapsulates the cellulosic fibers of the nonwoven fibrous substrate;
after the treating, drying the nonwoven fibrous substrate, and
after the drying, contacting an entirety of the cross-linked polymeric network with a solution of a cationic antimicrobial compound to maintain the cationic antimicrobial compound within the nonwoven fibrous substrate and the cross-linked polymeric network.
