Abstract: An elastic fiber is provided that includes polyurethane and/or polyurethaneurea and an additive such as polystyrene, an acrylic polymer, polyvinylpyrrolidone, copolymers thereof, derivatives thereof, and combinations thereof. The elastic fiber is useful in laminate structures, such as disposable hygiene articles as wells as in knit, woven and nonwoven fabric constructions.

Abstract: Elastic fibers with wax compositions which reduce surface friction and over-end-take-off tack without negatively impacting creep performance, fabrics, garments and laminates containing these fibers, and methods of preparing the same are provided.

Abstract: A method for unwinding yarn is provided that allows for maximizing the draft of the yarn, while monitoring tension. The method includes providing a yarn package including elastic yarn; choosing a selected draft for said elastic yarn; unwinding the elastic yarn from the yarn package from a driven roll to yarn processing equipment at the selected draft which is determined by a ratio of a speed of the yarn at the yarn processing equipment to a speed of the driven roll; measuring tension in the elastic yarn; and providing an alarm when said tension reaches a critical level.

Abstract: Fibers including a polyurethaneurea that is the reaction product of (a) a prepolymer including the reaction product of (i) a polyol including a copolymer of tetrahydrofuran and 3-methyltetrahydrofuran having a number average molecular weight of 1000 to 2000 and (ii) a diisocyanate; and (b) a chain extender, and fabrics and hygiene articles including such fibers.

Abstract: Elastic band products of high durability and quality are disclosed. Also disclosed are methods of producing durable, high quality elastic band products using modified anvil blocks, including shaped anvil blocks, anvil blocks with lateral protuberances and/or anvil blocks with teeth. The disclosed methods result in reduced elastic yarn thread slippage both during production and in the finished elastic band product.

Abstract: Included are polymer compositions including a polymer and about 0.1% to 25% by weight of a cellulose additive. The polymer composition is in the form of a film and the cellulose additive may be a cellulose ester such as cellulose acetate butyrate.

Abstract: Methods of making and using anti-tack additives for elastic fibers are disclosed. The elastic fibers include CE additive.

Abstract: An elastic thread transporting assembly and method provides for the transporting of thread to a production line. The assembly includes a thread creel for supplying multiple threads. The thread creel defines an unwinding location. A carrier is positioned for transporting the threads to the production line along a carrier path. An attachment device for attaching the threads to the carrier is provided. The attachment device is placed in close proximity to the unwinding location. The carrier path provides unrestricted access to the threads between the unwinding location and the production line.

Abstract: Anti-tack additives for elastic fibers and methods of preparing the same are included. The elastic fibers include a substituted cellulose additive.

Abstract: A stretch article comprising: a substrate comprising a substrate material, and at least one stretch yarn comprising an elastomeric propylene-based polymer, wherein the stretch yarn is bonded to the substrate and wherein the stretch yarn is capable of being mechanically bonded directly to the substrate surface.

Abstract: Anti-tack additives for elastic fibers and methods of preparing the same are included. The elastic fibers include a substituted cellulose additive.

Abstract: An apparatus and method for unwinding yarns with: (1) a drive roll with a polished metal finish to ensure good fiber/metal contact; (2) a drive roll/separator roll combination that enables multiple wraps of yarn on the drive roll; (3) pivoting yarn holding arms for the active and standby packages that provide for easier access to the packages on a frame; and (4) in combination with the pivoting yarn holding arms, one or more pivoting legs extending from a frame so that the apparatus has a relatively small footprint and simplified yarn threading/string-up as compared to background art OETO apparatus.

Abstract: A compact continuous over end take-off creel system with a tension control apparatus permits unwinding of high tack elastomeric threads from multiple thread packages. Thread tension is monitored and controlled through a variable speed motor of a driven take-off roll to maintain continuous operation of the creel system by avoiding breakage of elastomeric threads. Separate motors and thread tension sensors, optionally in combination with pretensioners, may be used for groups of threads or for individual threads.
