ABSTRACT:
Carrier dyeable polyester yarns are space dyed by spraying with water dispersions of disperse dyes without thickeners or carriers followed by a short steaming process and autoclaving to develop the dyes or by a knit-de-knit process of knitting the yarn into socks or tubes which are roller printed with disperse dyestuff, thickener and carrier dissolved in water in various colors followed by steaming, washing, drying and deknitting. The thus produced space dyed yarns are then tufted into area rugs along with undyed yarns of "carrierless" polyester fibers and/or nylon fibers and dyed with a cationic, acid or disperse dye appropriate to the dye receptivity of the undyed yarns while avoiding overdyeing of the space dyed yarns to produce a multicolor piece-dyed area rug.
