Abstract: Yarns showing novel color effects varying along their length are made by feeding a thermoplastic yarn into a confined space, so forming a long stack of uniform cross section of folded yarn in the said space, by means of a jet of fluid at a temperature sufficient to set the resulting crimp in the yarn, and feeding a dye solution, preferably two or more dye solutions at different locations to the same cross section of the stack, under conditions such that the resulting intensity of color of the yarn due to each dye falls off across the stack from the point or points of application.
