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.

Process for draft control on feeding of elastic yarn

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.

Polymer compositions including cellulose ester

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

Methods of making and using elastic fiber containing an anti-tack additive

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

Elastic fiber containing an anti-tack additive

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.
