Acidified polyamidoamine adhesives, method of manufacture, and use for creping and ply bond applications

摘要

A paper adhesive composition includes a cationic non-crosslinked acidified solution of a polyamidoamine with the repeating units;
wherein n≧1; m=1 or 2; X−m is chloride, bromide, iodide, sulfate, bisulfate, nitrate, oxalate, alkyl carboxylate, aryl carboxylate, hydrogen phosphate, dihydrogen phosphate, alkyl sulfonate, aryl sulfonate, or a combination comprising at least one of the foregoing anions; R1 is a divalent aliphatic, cycloaliphatic, or araliphatic group having from 1 to 24 carbon atoms; R2 is hydrogen or a monovalent aliphatic, cycloaliphatic, or araliphatic group having from 1 to 24 carbon atoms; and R3 is a divalent hydrocarbon radical derived from a dibasic carboxylic acid. Also disclosed are methods of creping paper with the composition.

主权项

1. A method of creping paper, comprising:
applying to a rotating cylinder a polymer solution, wherein the polymer solution is a mixture consisting of 0.1 to 10 wt % of a cationic non-crosslinked polyamidoamine and water, wherein the cationic non-crosslinked polyamidoamine is free of epihalohydrin, and wherein the mixture has a pH of less than 6.9; pressing a tissue paper web against the rotating cylinder to effect adhesion of the tissue paper web to a surface of the cylinder using the cationic non-crosslinked polyamidoamine; and dislodging the tissue paper web from the rotating cylinder by contact with a doctor blade to form the creping paper.
