Abstract
A method and apparatus for the space dyeing of yarn while the yarn is in the form of a loosely gathered package, such as a conventional yarn skein, and which includes injecting an atomized spray of dye and air at a plurality of spaced apart locations in the package, and such that the dye contacts only a portion of the yarn. The resulting yarn is characterized by essentially random and relatively short colorband lengths, which avoid the formation of unsightly streaks or "chevrons" on the face of a fabric formed from the yarn.
