A creping adhesive for applying to a creping surface in the process for dry creping tissue and or towel paper is disclosed. The adhesive comprises a blend of at least two water-soluble cationic polyamide-epihalohydrin (PAE) resins. The first PAE resin has a mole ratio of epihalohydrin to secondary amine groups of the polyamine ranging from about 0.5:1.0 to about 1.8:1.0; and the second PAE resin has a mole ratio of epihalohydrin to secondary amine groups of the polyamine less than 0.5:1.0. The weight percent of the solids in the admixture or blend in an aqueous solution ranges from about 40% to about 0.01% solids, wherein the solids in this admixture are comprised of from about 0.1% to about 50.0% by weight of the first PAE resin and from about 99.9% to about 50.0% by weight of the second PAE resin. Varying the percentages of the two PAE resins in the creping adhesive can produce desired levels of adhesion and water resistance for given grades of tissue and/or towel paper products.
A creping adhesive for preparing creped paper comprising an admixture of from about 0.1 to about 50 weight percent of a first polyamide-epihalohydrin resin and from about 99.9 to about 50 weight percent of a second polyamide-epihalohydrin resin, said first polyamide-epihalohydrin resin and said second polyamide-epihalohydrin resin each being made by the reaction of a polyalkylene polyamine having at least one secondary amine group with a dicarboxylic acid to form a long chain polyamide containing the recurring groups:
A process for creping tissue and/or towel paper comprising:
