  • Fluorochemical compound useful for textile treatment
    Patent number: 4160777
    Abstract: Textiles, particularly carpets, are endowed with oil and water repellency and soil resistance by treatment thereof with certain detergent-compatible fluorochemmical compounds which can also be used in conjunction with anionic or nonionic detergents to provide cleaning/treating compositions for cleaning such textiles simultaneously with the treatment. The textile treating compositions of the invention comprise certain detergent-compatible fluorochemical compounds which are dissolved and/or dispersed in a suitable liquid vehicle. The textile treating/cleaning compositions of the invention also contain an anionic and/or a nonionic detergent.
    Type: Grant
    Filed: January 14, 1977
    Date of Patent: July 10, 1979
    Assignee: Minnesota Mining and Manufacturing Company

  • Cleaning and treating compositions
    Patent number: 4145303
    Abstract: Container-stable alkaline cleaning compositions and processes are provided which are effective for cleaning carpets, upholstery and the like, and for imparting water and oil repellency and stain resistance thereto. One such composition comprises in an aqueous medium: detergent, water-dispersible carboxyl-containing material which forms water-insoluble zinc or zirconium salts, a water-dispersible zinc or zirconium coordination complex, a Lewis base, and a fluorochemical compound containing a fluoroaliphatic group and having acid functionality and being capable of imparting water- and oil-repellency to a substrate.
