Abstract
A process for forming a spaced dyed yarn, where a yarn is conveyed to a dye application station where a coordinated stream of dye is projected in a normal stream path adjacent to a first side of the yarn. The dye is applied to the yarn when a gas nozzle projects a stream of gas such that it impinges the stream of dye and diverts the stream of dye across said yarn to an alternative deflected path adjacent to the opposite side of said yarn, causing the dye to sweep over the yarn and impact and color the yarn. Upon deactivation of said gas nozzle, the stream of dye passes back across said yarn to the first side of the yarn, impacting and coloring the yarn for a second time.
