ABSTRACT:
A method and means for multi-color dyeing textile yarn wherein yarn is present in perforate cylindrical cans for dyeing, with the yarn being in a maze of tortuously extending coils progressing axially within the can as occurs when yarn is collected in an upright can from a crimping or bulking operation. The cans are first positioned on movable J-shaped cradles with their cylindrical axes horizontal and are then immersed sequentially in a plurality of dye baths in which the cans are only partially immersed. Between immersions in sequential dye baths the cans are reoriented by rotating them about their cylindrical horizontal axes to cause dyeing of at least partially different portions of the maze of yarn in the cans in the different dye baths so that the resulting yarn strand, which extends randomly in the maze throughout differently dyed portions, will be unpredictably randomly dyed in different colors and lengths of color.
