Abstract:
A method of moist creping absorbent paper base sheet includes forming a nascent web including at least a major portion of flattened ribbonlike cellulosic fibers of recycled fiber. A creping adhesive coating including an admixture of polyvinyl alcohol and a polyamide crosslinked with epichlorohydrin is applied to a Yankee dryer. The nascent web is passed through a nip, defined between a suction pressure roll and the Yankee dryer, having a controlled loading. The nascent web is adhered to the Yankee dryer and dried on the Yankee dryer to a moisture content corresponding to a sheet temperature, immediately prior to the creping blade, of from about 110° C. to about 121° C. The nascent web is creped at a sheet temperature of from about 110° C. to about 121° C. from the Yankee dryer with an undulatory creping blade bearing against the Yankee dryer to form a moist biaxially undulatory web, which is dried.
