This invention is method of producing a creping cylinder adhesive comprising: contacting a dry form PVOH with a liquid form PVA at a temperature of less than 80&#xb0; C., maintaining the PVOH and PVA at a temperature of between 90-95&#xb0; C. until the PVOH is completely dissolved into a medium, and allowing the medium to cool to below 80&#xb0; C.

Method of producing creping adhesive

This invention is method of creping a paper web comprising a) applying to a rotating creping cylinder an adhesive composition having a pH of about 6.5 to about 8 and comprising one or more vinylamine/N-vinyl formamide polymers composed of about 10 to about 99 mole percent vinylamine monomer and about 90 to about 1 mole percent N-vinylformamide monomer; b) pressing the paper web against the creping cylinder to effect adhesion of the paper web to the creping cylinder; and c) dislodging the paper web from the creping cylinder with a doctor blade.

Method to adhere and dislodge crepe paper

The invention provides a composition of matter used to produce very soft high grades of tissue paper. The composition of matter comprises a PAE resin acidified with a multifunctional acid. The multifunctional acid includes but is not limited to carboxyl and sulfonyl. The acid has a functional group selected from carboxyl and sulfonyl and a functional group selected from carboxyl, sulfonyl, hydroxyl, lactone, phenol, amine and heterocycle. The PAE resin facilitates the use of an adhesive in a Yankee Dryer apparatus that is durable when the adhesive is wet but remains soft when the adhesive becomes dry. These properties allow the adhesive to be strong and remain engaged to the dryer apparatus when wet but be easily removed by the creping blade when dry.
