Abstract
Methods of and apparatus for treating yarn with a fluid material include a chamber through which the yarn is advanced and an injection nozzle for impinging fluid on the yarn as it advances through the chamber. The injection nozzle is registered with a fluid circulation system in which a dyeing substance or other fluid treating substance or material is circulated. Upon interrupting the circulation of the fluid treating material, a portion of the material is diverted into the chamber through which the yarn is advancing. By interrupting the circulation of the fluid treating material according to a selected pattern, the fluid treating material will impinge on the advancing yarn with a corresponding pattern. If it is desired to impinge treating materials having different characteristics, such as dyes of different colors, then a plurality of circuits may be utilized to direct the fluid materials into the chamber through which the yarn advances. The fluid circuits may be controlled and coordinated according to selected patterns in order to produce a varying effect on the yarn progressing through the chamber.
