  • Process of making low surface energy fibers
    Patent number: 6630087
    Abstract: The present invention relates to a textile filament with a contact angle greater than or equal to 90 degrees. Such filaments are either water-repellent or resistant to chemicals, and yarns made therefrom readily processible into fabrics. In a detailed embodiment, the filaments are water-repellent and comprise a first longitudinally-extending component comprising at least one polymer selected from nylon, polyester, polypropylene, or other filament-forming polymer, and a second longitudinally-extending component, comprising a halogenated polymer. In a second detailed embodiment, the filaments are chemical-resistant and comprise a first longitudinally-extending component comprising at least one fiber-forming polymer and a second longitudinally-extending component comprising an olefin copolymer. In both embodiments, the second longitudinally-extending component is present on the exterior of the first longitudinally-extending component.
    Type: Grant

  • Binder fiber for improved carpet appearance retention and endpoint
    Publication number: 20030165656
    Abstract: A carpet fiber yarn having carpet fiber and binder material, the yarn being subjected to singeing to remove protruding fiber ends, and subjected to heat sufficient to melt the binder fiber, wherein initial appearance and trafficked appearance of a first test carpet having a pile comprised of the yarn is improved over a corresponding second test carpet having a pile comprised of an unsinged yarn with the carpet fiber and the binder fiber, the unsinged yarn also being subjected to heat sufficient to melt the binder fiber.

  • Low surface energy fibers
    Patent number: 6287689
    Abstract: The present invention relates to a textile filament with a contact angle greater than or equal to 90 degrees and a tenacity of 2.0 g/den. Such filaments are either water-repellent or resistant to chemicals, and yarns made therefrom readily processible into fabrics. In a detailed embodiment, the filaments are water-repellent and comprise a first longitudinally-extending component comprising at least one polymer selected from nylon, polyester, polypropylene, or other filament-forming polymer, and a second longitudinally-extending component, comprising a halogenated polymer. In a second detailed embodiment, the filaments are chemical-resistant and comprise a first longitudinally-extending component comprising at least one fiber-forming polymer and a second longitudinally-extending component comprising an olefin copolymer. In both embodiments, the second longitudinally-extending component is present on the exterior of the first longitudinally-extending component.
