Patent ID: 7131158

Claim:
A process for applying dye to a yarn, the yarn having a first side and a second side opposite the first side, the process comprising: conveying said yarn to at least a first dye application station; delivering a coherent stream of dye from said dye station in a normal stream path adjacent to and in non-contacting relation with the first side of said yarn; and intermittently activating and deactivating a gas nozzle projecting towards said coherent stream of dye such that upon activation of said gas nozzle, a stream of gas impinges said coherent stream of dye thereby diverting said coherent stream of dye across said yarn to an alternative deflected path adjacent to and in non-contacting relation with the second side of said yarn, whereby said dye impacts said yarn in a coherent stream and colors said yarn and such that upon deactivation of said gas nozzle, the coherent stream of dye passes back across said yarn whereby said dye impacts said yarn in a coherent stream and colors said yarn.
