  • Amine-, polyol-, amide-functional siloxane copolymers and methods for their preparation
    Patent number: 6255429
    Abstract: An amine-, polyol-, amide-, dimethyl-functional siloxane copolymer and a method for its preparation are disclosed. The copolymer is suitable for use in fiber treatment compositions. The copolymer provides good hand, resistance to yellowing, and hydrophilicity to fibers treated therewith.
    Type: Grant
    Filed: September 2, 1999
    Date of Patent: July 3, 2001
    Assignee: Dow Corning Corporation
    Inventors: Howard Edwin Griffin, Linda Denise Kennan, Michael Ward Skinner, Kenneth Edward Zimmerman
  • Fiber treatment composition containing amine-, polyol-, functional siloxanes
    Patent number: 6171515
    Abstract: A fiber treatment composition is disclosed. The composition contains siloxanes having amine-, polyol-, functionalities. The composition provides good hand, resistance to yellowing, and hydrophilicity to the fibers. The composition is preferably formulated as an aqueous emulsion. Applying the composition to textile fabrics produces treated fabrics having good hydrophilicity, good hand, and resistance to yellowing.

  • Method for forming fiber treating composition comprising an amide-functional polyorganosiloxane and an alkylsulfate of benzimidazole
    Patent number: 6048927
    Abstract: A method for forming a fiber treating composition comprising contacting an aminofunctional polysiloxane comprising at least one aminofunctional siloxy unit with a mixture comprising a lactone and an alkylsulfate of benzimidazole thereby effecting formation of an amide-functional polysiloxane in admixture with the alkylsulfate of benzimidazole. The composition formed by the method is particularly useful for treating textiles such as cotton and cotton-synthetic blends to provide good softness and water absorbency and improved whiteness and treatment durability.
