Abstract:
1. A process for forming a creped paper product comprising: applying an adhesive formulation comprising a polyamine-polyamidoamine-epihalohydrin (PPAE) resin to a drying surface, wherein the PPAE resin is a reaction product of three components: a first polyamine, a polyamidoamine, and an epihalohydrin, and wherein the polyamidoamine is prepared by a process comprising reacting a polycarboxylic acid and/or a polycarboxylic acid derivative with a second polyamine to form the polyamidoamine, wherein a molar ratio of the second polyamine to the polycarboxylic acid and/or polycarboxylic acid derivative is 1.05 to 2.0, wherein the first polyamine is selected from the group consisting of: aliphatic amines, aromatic amines, polyalkylenepolyamines, and a mixture thereof; pressing a paper web against the drying surface to effect adhesion of the paper web to the surface; and dislodging the paper web from the drying surface by contact with a doctor blade to form the creped paper product.
