ABSTRACT:
A process for making a cellulosic pulp fiber web having increased wet strength comprising the steps of: (1) adding to an aqueous cellulosic pulp fiber slurry a water soluble cationic polymer consisting of polydimethyldiallylammonium chloride to form a first treated slurry; (2) adding to the first treated slurry an aminopolyamide-epichlorohydrin acid salt resin solution having an E/N ratio of from about 0.6 to about 2.0 so that the weight percent of the cationic polymer is from about 1% to about 35% based on the weight of the resin, thus forming a second treated slurry; and (3) forming a cellulosic pulp fiber web by dewatering the second treated slurry.
