Abstract
A method of winding bulked continuous filament yarn is disclosed, which enables superior yarn package formation, including higher density packages with excellent shape and yarn takeoff characteristics. The method uses unique helix angles and winding profiles in a non-adjacent and adjacent yarn pattern, achieved by a unique winding control strategy that constantly monitors spindle speed, desired wind ratio, traverse cam speed, and surface speed.
