Zusammenfassung:	A method and composition are disclosed for providing a two-part polymer binder additive for a fibrous sheet by improving both its strength and durability. The polymer binder comprises both the addition of a resin system and an anionic polymer which impart both increased strength and resistance to moisture and sagging. The resin system includes a polyamidoamine-epihalohydrin resin, a latex and an anionic polymer.
