  • Patent number: 6187138
    Abstract: A method for producing creped paper products comprising applying to a drying surface, a film-forming semi-crystalline polymer and a non-thermosetting cationic resin wherein the resin is characterized by a highly branched structure that lacks reactive intralinker functionality and which has a prepolymer backbone comprised of intralinked polyamidoamine. The invention also comprises a method for producing creped paper products comprising applying to a drying surface a film-forming semi-crystalline polymer, a non-thermosetting cationic resin wherein the resin is characterized by a highly branched structure that lacks reactive intralinker functionality and which has a prepolymer backbone comprised of intralinked polyamidoamine, and an optional plasticizer.
    Type: Grant
    Filed: March 17, 1998
    Date of Patent: February 13, 2001
    Assignee: The Procter & Gamble Company
    Inventors: Charles William Neal, Lois Jean Forde-Kohler, Donald Arthur Salsman
  • Patent number: 6048938
    Abstract: A method for producing creped paper products comprising applying to a drying surface, a film-forming semi-crystalline polymer and a non-thermosetting cationic resin containing no secondary amine. The invention also comprises a method for producing creped paper products comprising applying to a drying surface a film-forming semi-crystalline polymer, a non-thermosetting cationic resin containing no secondary amines and an optional plasticizer.
    Type: Grant
    Filed: March 31, 1999
    Date of Patent: April 11, 2000
    Assignee: The Procter & Gamble Company
    Inventors: Charles William Neal, Lois Jean Forde-Kohler, Donald Arthur Salsman
  • Patent number: 5958185
    Abstract: Soft, strong, and low dusting tissue paper webs useful in the manufacture of soft, absorbent sanitary products such as bath tissue, facial tissue, and absorbent towels are disclosed. The tissue papers comprise fibers such as wood pulp and a non-cellulosic, water insoluble particulate filler such as kaolin clay and possess biased surface properties.

    Type: Grant
    Filed: December 22, 1997
    Date of Patent: August 24, 1999
    Assignee: The Procter & Gamble Company
    Inventors: Charles William Neal, Lois Jean Forde-Kohler, Donald Arthur Salsman
  • Patent number: 5858554
    Abstract: A multi-ply paper product wherein the plies are adhesively joined together. One or both of the plies may have embossments protruding towards and contacting the other ply. The plies are adhesively joined, preferably at such embossments. The adhesive is selected from a composition that advantageously provides a minimum wet ply bond strength and a dry ply bond strength which falls within a particularly desired range.
