Abstract
Chevroning of fabrics made from skein dyed yarns is avoided or controlled by dyeing the yarns such that the color repeat length is greater than the circumference of the skein. In practice this is achieved by horizontally dyeing only a portion of the width of a skein as the skein is held vertically.

Apparatus for random skein dyeing of yarn, including rotatable support means for axially supporting and rotating at least one skein thereon, first and second dye delivery means below said support member and spaced apart on opposing sides of said skein and generally parallel to said sides, said first dye delivery means being adjacent an exterior side of said skein and said second dye delivery means extending through said skein, said dye delivery means having dye discharge outlets positioned to discharge dye to at least one discrete location on said skein but to less than the number of locations effective for dyeing across the full width of said skein, and said dye delivery means being devoid of other dye discharge outlets.
