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 translation: 提供一种用于退绕纱线的方法，其允许在监测张力的同时使纱线的牵伸最大化。 该方法包括提供包括弹性纱线的纱线卷装; 选择所选弹力纱的选择草图; 从所述纱线卷装将所述弹性纱线从所述从动辊到所述纱线加工设备以选定的通风速度退绕，所述纱线加工设备由所述纱线处理设备的纱线速度与所述从动辊的速度的比率确定; 测量弹性纱线的张力; 并且当所述张力达到临界水平时提供警报。
