    Abstract: The present invention relates to a melt blend of a base polymer, an oxidizable organic polymer, a transition metal salt catalyst and a colorant that does not completely deactivate the catalyzed oxidation. A preferred colorant, yields in an article made from the polymer melt blend a Catalyst Deactivation Factor (CDF) of less than about 0.25, preferably less than 0.15, more preferably less than 0.1, and most preferred less than 0.05. The present invention also comprises a colored monolayer article having the described CDF, such as a film, thermoformed tray, or blow molded container, that has active oxygen scavenging properties. The colorant, after melt blending a base polymer, an oxidizable organic polymer, a transition metal catalyst, does not increase the binding energy of the transition metal catalyst ion by more than 1 eV.

    Abstract: The present invention relates to a compact creel using the OETO method that accommodates an increased number of packages in a relatively small footprint while providing a straight in-line delivery path in which fiber bends and changes in direction are minimized. In addition, the present invention is a system, apparatus and method for tension control in a fiber feeding system that provides a fast and reliable method for feeding high tack elastomeric thread or fiber from a package to a manufacturing process. Furthermore, the present invention provides a method and apparatus for changing packages on a creel without interrupting the manufacturing process. In particular, the compact creel of the present invention provides for continuous operation of unwinding and fiber delivery by allowing a standby package to be loaded on the same mandrel as an active package that is presently being unwound.

    Abstract: The invention provides a profiled polymer filament having an open hollow cross-sectional shape normal to the longitudinal axis of the filament, wherein the cross-section is dimensioned to prevent the filament from interlocking with a second filament of the same cross-section. The invention also provides methods of manufacture of such filaments by melt spinning a polyamide, and spinnerets suitable for use in melt spinning such filaments.

    Abstract: A continuous method for producing composite elastic yarns at speeds up to 700 m/min by (a) stretching (drafting) an elastomeric yarn (e.g., spandex) by 2.0x (100%) to 10.5x (950%) while heating (max. heating temperature 220 DEG C) in a single or double stage draft, (b) air-jet entangling with a relatively inelastic yarn component to create a composite elastic yarn, and then (c) in-line heat-treating (max. heating temperature 240 DEG C) the composite elastic yarn. The initial draft stage(s) may also be carried out at ambient temperature. The resulting composite elastic yarn has improved stitch clarity, particularly suited for hosiery, and its properties can be tailored to provide fabric properties for knit and woven fabrics hitherto not possible with standard spandex yarns.
