A belt for creping a web in a papermaking process. The belt includes a surface onto which the web is transferred during the papermaking process. A plurality of openings extend through the surface, with the openings being arranged in lines that are offset from lines in the machine direction (MD) and cross-machine direction (CD) of the belt. Paper products, such as absorbent sheets, made from the belt have hollow dome regions and connecting regions between the domes, with the domes being arranged in lines that are offset from lines in the MD and CD of the paper products.

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.
