  • Papermaking process
    Patent number: 5595629
    Abstract: A papermaking process comprising forming an aqueous cellulosic papermaking slurry and adding a cationic polymer and an anionic polymer to the slurry to increase retention and/or drainage is disclosed. The anionic polymer comprises a formaldehyde condensate of a naphthalene sulfonic acid salt (NSF) with a molecular weight range of 500 to 120,000, while the cationic polymer has a molecular weight range of from 500,000 to 20 million. After addition of the polymers, the slurry is drained to form a sheet, and the sheet is dried.

  • Papermaking process with improved retention and drainage
    Patent number: 5185062
    Abstract: A papermaking process includes the steps of adding to the papermaking cellulosic slurry first a high molecular weight cationic polymer and then a medium molecular weight anionic polymer, to improve drainage and retention. The anionic polymer includes ionizable sulfonate.
    Type: Grant
    Filed: March 17, 1992
    Date of Patent: February 9, 1993
    Assignee: Nalco Chemical Company
    Inventor: Arthur J. Begala
  • Papermaking process with improved retention and drainage
    Patent number: 5098520
    Abstract: A papermaking process includes the steps of adding to the papermaking celllulosic slurry first a high molecular weight cationic polymer and then a medium weight anionic polymer. The cationic polymer is added after the addition of filler, but before at least one of the shear stages to which the slurry is subjected prior to sheet formation and drainage. The anionic polymer is added after the shear stage which is subsequent to the addition of the cationic polymer.
