  • Antisoiling treatment of synthetic filaments
    Patent number: 4565717
    Abstract: Antisoiling properties of polyamide filaments are enhanced upon melt-spinning by using a spin finish comprised of a textile lubricant, an antisoiling fluorochemical and an epoxy resin.
    Type: Grant
    Filed: October 20, 1983
    Date of Patent: January 21, 1986
    Assignee: E. I. DuPont De Nemours and Company
    Inventors: Edward A. Hosegood, Ludwig E. Seufert
  • Durable antisoiling coatings for textile filaments
    Patent number: 4388372
    Abstract: A durable antisoiling coating composition for textile filaments comprises a perfluoroalkyl ester of a citric acid urethane and fluorinated alcohols in combination with a modified epoxy resin which is the reaction product of a carboxyl-functional vinyl polymer, an epoxy resin and a tertiary amine. The composition can be applied as an aqueous dispersion, including a non-ionic textile lubricant based on poly(ethylene glycol).
    Type: Grant
    Filed: March 10, 1982
    Date of Patent: June 14, 1983
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Nitin J. Champaneria, Lee R. Harper, Edward A. Hosegood
  • Durable antisoling coatings for textile filaments
    Patent number: 4325857
    Abstract: A durable antisoiling coating composition for textile filaments and articles made therefrom comprises a perfluoroalkyl ester of a citric acid urethane and fluorinated alcohols in combination with a modified epoxy resin which is the reaction product of a carboxyl-functional vinyl polymer, an epoxy resin and a tertiary amine. The composition can be applied as an aqueous dispersion, including a non-ionic textile lubricant based on poly(ethylene glycol). The dispersion can be used as a spin finish to provide durable protection to filaments, particularly nylon filaments.
