Zusammenfassung:	Improvements to absorbent sheet manufacture include spraying a softener onto the web and providing a creping adhesive to a surface of a heated drying cylinder of a Yankee dryer such that a creping adhesive coating is formed, the creping adhesive comprising a poly(aminoamide)epihalohydrin (PAE) resin and a polyvinyl alcohol copolymer, wherein the polyvinyl alcohol copolymer includes functional repeat units selected from carboxylate repeat units, sulfonate repeat units as well as combinations of the comonomers. A preferred PAE resin is fully crosslinked PAE resin.
