Appl. No.:

10/910047

Inventors:

Charles William Neal - Fairfield OH, US
Edward Aprahamian, Jr. - Cincinnati OH, US
James Allen Cain - Leesburg GA, US

Assignee:

The Procter & Gamble Company - Cincinnati OH

International Classification:

D21H 21/14

US Classification:

525 56, 525 55, 525178, 525185

Abstract:

The present invention relates to a creping aid composition comprising a film-forming semi-crystalline polymer and a vehicle system comprising a cationic polymer resin, a water soluble anionic film forming polymer, and water, wherein the net Mutek charge of the vehicle system is less than about −200 μeq/g solid and the pH of the creping aid composition is greater than the pH of the vehicle system. The present invention also relates to methods of producing paper products comprising the steps of a) providing a fibrous structure having a first surface and a second surface; b) providing a drying surface; c) applying a creping aid composition whereby the creping aid composition contacts one of the drying surface or the fibrous structure, said creping aid composition comprising i) a film-forming semi-crystalline polymer and ii) a vehicle system comprising a cationic polymer resin, a water-soluble anionic film-forming polymer, and water, wherein the net Mutek charge of the vehicle system is less than about −200 μeq/g solid and the pH of the creping aid composition is greater than the pH of the vehicle system; d) applying the fibrous structure to the drying surface such that the fibrous structure, the creping aid composition and the drying surface are all in contact; e) removing the fibrous structure from the drying surface.
