摘要:
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.

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.
摘要:
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.
摘要:
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.

摘要:
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.
