  • Tacky polymer melt spinning process
    Patent number: 7261849
    Abstract: A method for high speed melt spinning of binder fiber by melting a polymer having a melting temperature range of greater than 0° C. to 160° C., spinning said polymer at a speed of greater than about 2000 meters per minute to form the binder fibers; and winding the binder fiber onto a spin bobbin.
    Type: Grant

  • Tacky polymer melt spinning process
    Publication number: 20030201568
    Abstract: A method for high speed melt spinning of binder fibers by melting a polymer that exhibits substantially no exothermic crystallization peak as measured by DSC when it is cooled to solidification from a molten state according to test A, spinning said polymer at a speed of greater than about 2000 meters per minute to form said binder fibers; and winding said binder fiber onto a spin bobbin.

  • 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.

  • Nylon fiber blends for saxony carpets
    Patent number: 5593751
    Abstract: A yarn formed from a blend of nylon fibers is disclosed. The yarn exhibits improved bulk characteristics and, when utilized as pile yarn in carpet constructions, provides a carpet with improved appearance retention properties with respect to tuft endpoint definition and lack of matting.

  • High tenacity nylon yarn
    Patent number: 5073453
    Abstract: A process for producing high tenacity nylon yarn is described. The process comprises a melt-spinning step for producing an as-spun yarn, a solid state polymerization step for increasing the Mw and changing the crystalline characteristics of the nylon polymer of the as-spun yarn, and a drawing step for increasing the tenacity of the yarn.

  • Stopping/restarting free radical polymerizations
    Patent number: 4433122
    Abstract: A method for stopping and restarting the free-radical polymerization of vinyl monomers (e.g. acrylic monomers) without forming low molecular weight polymer is provided. These polymerizations utilize a Redox catalyst system comprising multivalent metal ions (e.g. iron ions) as promoter. The polymerizations are stopped by chelation of the iron present. Additional monomer is added to the polymerization to avoid formation of low molecular weight polymer. Upon restart metal ions are added to the polymerization mixture.
