Abstract
A process for package dyeing yarn is disclosed. Yarn is wound on a tube having perforations along a portion of its length. The density of the yarn package is such that when dye liquor is circulated from the interior of the tube, through the perforations and then through the yarn, its path of flow is different from when dye is circulated in the opposite direction. By circulating and absorbing dyes of different colors in each direction, multicolored dyeing of the yarn is achieved.
