    6562194, May 13, 2003
  • Filed:
    Mar 30, 2000
  • Appl. No.:
    09/538839
  • Inventors:
    Sammy L. Archer - Lynnwood WA
    Robert E. Dristas - Canonsburg PA
    Ross T. Gray - Moon Township PA
  • Assignee:
    Calgon Corporation - Naperville IL
  • International Classification:
    B31F 112
  • US Classification:
    162111, 162112, 162113, 264283
  • Abstract:
    A non-oil-based release aid used in a creping process for releasing a paper web from a Yankee dryer in the manufacture of a paper product having a formula for its block version as follows: where R is a C to C alkyl or alkylaryl group, y plus z is greater than 20, and y is greater than z. The y moles of propylene oxide (OC H ) and the z moles of ethylene oxide (OC H ) may be added in random or block fashion. Examples of the chemical compound for the release aid are alkoxylated alkylphenols, alkoxylated fatty acids, and alkoxylated alcohols. A preferred chemical compound is an alkoxylated tall oil fatty acid. The release aid may optionally comprise from about 0% to about 20% by weight of an emulsifying surfactant. The release aid may comprise 70% to 100% by weight of the chemical compound, 0% to 20% by weight of emulsifying surfactants, and 0% to 10% by weight water. The release aid provides lubrication between the doctor blade and the Yankee dryer; allows the release of the paper web from the Yankee dryer, and improves the absorbency of the paper product.

  • International Classification:
    B31F 112
    D21H 1500
  • US Classification:
    162111
  • Abstract:
    A creping adhesive for applying to a creping surface in the process for dry creping tissue and or towel paper is disclosed. The adhesive comprises a blend of at least two water-soluble cationic polyamide-epihalohydrin (PAE) resins. The first PAE resin has a mole ratio of epihalohydrin to secondary amine groups of the polyamine ranging from about 0. 5:1. 0 to about 1. 8:1. 0; and the second PAE resin has a mole ratio of epihalohydrin to secondary amine groups of the polyamine less than 0. 5:1. The weight percent of the solids in the admixture or blend in an aqueous solution ranges from about 40% to about 0. 01% solids, wherein the solids in this admixture are comprised of from about 0. 1% to about 50. 0% by weight of the first PAE resin and from about 99.
