摘要：
A method for making paper to enhance its wet strength includes adding separately to a cellulosic paper pulp furnish the following additives to form a treated pulp: a cationic wet strength resin whose cationic sites bond to anionic sites of cellulose fibers contained in the paper pulp furnish, and a hydrophobically modified anionic polyelectrolyte whose anionic sites bond with cationic sites of the cationic wet strength resin.
