  • Publication number: 20040131822
    Abstract: An ozone fade resistant dyed carpet made of dyed sheath/core face fibers has a sheath substantially or completely covering the core. The sheath is composed of a fiber-forming polymer which is inherently chemically compatible and is selected from polymers that are resistant to dye migration and yet inherently chemically compatible with the core polymer. The face fibers are dyed with at least one acid dye, basic dye or disperse dye and resist ozone fading as indicated by a CIEL*a*b* total color difference from the original unexposed sample after at least 3 cycles of ozone fading that is less than one-half of the CIEL*a*b* total color difference seen for a fiber composed substantially completely of said core polyamide component that is dyed with the same dyes. The fibers may be cabled and heatset in which case even more substantial improvement in the ozone fastness is observed.

  • Patent number: 6531218
    Abstract: Dyeable and dyed filaments have a core and a sheath which entirely surrounds the core. The core is formed of a core polymer which is susceptible to dyeing by a dye bath chemical, while the sheath is formed of a sheath polymer which is resistant to dyeing by the dye bath chemical. When the filament is brought into contact with a dye bath containing the dye chemical, the dye chemical in the dye bath will physically diffuse or migrate through the sheath polymer to cause the core polymer to be dyed a color of the dye bath chemical, while the sheath polymer is substantially undyed thereby.

  • Patent number: 6416859
    Abstract: Polymeric compositions include a nonaqueous additive system having dispersant-coated pigments physically dispersed in a liquid nonaqueous polymeric carrier which may be added directly to a melt flow of a polymeric host material. The additive system employed in the polymeric systems is most preferably in the form of a particulate paste which can be added in metered amounts (dosed) to a melt flow of the polymeric host material prior to being spun into filaments. By providing a number of additive systems having a number of different additive attributes, and controllably dosing one or more into the melt flow of host polymeric material, shaped objects of the polymeric material (e.g., melt-spun filaments) having different additive attributes may be produced on a continuous basis without shutting down the shaping operation.

  • Patent number: 6358458
    Abstract: Stabilized solution-dyed fiber is made by melting a polyamide which is amide monomers polymerized in the presence of at least one hindered piperidine compound, coloring the melted polyamide, and spinning the colored polyamide into fibers that have about 40% or better retained tenacity after 2125 kJ exposure to xenon arc radiation as per AATCC Test Method 16-1993, “Colorfastness to Light,” Option E. Copper stabilizers are unnecesssary.
