  • Production of variegated polyester yarn and fabric
    Patent number: 4087242
    Abstract: A polyester yarn is treated, so that it may be dyed in yarn or fabric form to a variegated appearance, by running partially oriented polyester feeder yarn over a surface wetted with a liquid reagent which alters the affinity of the yarn to a disperse dye, followed by drawing or draw-texturing. The surface may be a groove formed across the tip of a capillary tube wherein the groove is wetted by a liquid reagent supplied through the bore of the tube. Intermittent contact between the feeder yarn and the reagent is thereby obtained.
