Abstract
A layered yarn package is formed of continuous filament yarn wads wherein the yarn alternates between compacted an extended lengths by axially compacting the yarn into a length, segmenting the length into alternating extended and compacted lengths then arranging the compacted lengths in a common axial direction one next to the other to form a layer. The layer may be compressed. One or more layers may form the package.
