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.
Claims17
A method for asymmetric dyeing of yarn, comprising positioning a skein of yarn for rotation in a vertical plane and while said skein is stationary, applying at least one color contrast dyestuff 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, said dyestuff being applied simultaneously to at least one discrete exterior location and to at least one discrete interior location on said skein corresponding to said exterior location, and repeating the application of the same or other contrast dyestuff after rotating the skein to one or more other stationary positions, whereby irregular dyeing along the lengths of yarn in the skein is obtained.
