  • Compositions and methods for imparting stain resistance and stain resistant articles
    Patent number: 5952409
    Abstract: A stainblocking composition comprises a stainblocking material and a complex of organoborane and amine. The stainblocking composition is particularly useful in imparting stain resistance to fibrous substrates that contain polyamide linkages, especially nylon carpet.
    Type: Grant
    Filed: July 1, 1996
    Date of Patent: September 14, 1999
    Assignee: 3M Innovative Properties Company
    Inventors: Gail S. Boardman, Larry D. Boardman
  • Aqueous anti-soiling composition
    Patent number: 5714082
    Abstract: This invention provides compositions suitable for treating fibrous substrates to render them durably resistant to dry soil and durably repellent to water and oil. One composition is an aqueous emulsion comprising: a dry soil resistant and water and oil repellent fluorochemical treatment and an effective amount of one or more fluorochemical surfactants wherein the surfactants comprising one or two fluorochemical groups and one or two water-solubilizing polar groups. Another composition is an aqueous emulsion comprising: a dry soil resistant and water and oil repellent fluorochemical treatment; an effective amount of one or more fluorochemical surfactants wherein the surfactants comprising one or two fluorochemical groups and one or two water-solubilizing polar groups; and one or more non-fluorinated additives.
    Type: Grant
    Filed: June 2, 1995
    Date of Patent: February 3, 1998
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Gail S. Boardman, Steven J. Martin, Aaron D. Otteson, Jeffrey G. Linert, Pamela A. Wolf, Roger R. Alm
  • Composition comprising thermoplastic polymer and fluorochemical piperazine compound
    Patent number: 5451622
    Abstract: Mixtures comprising thermoplastic polymer, such as polypropylene, and fluorochemical piperazine are provided. Shaped articles, such as fibers, made from these mixtures have low surface-energy surfaces which results in oil- and water-repellency and anti-soiling properties.
