ABSTRACT:
A method and apparatus for dyeing or otherwise treating yarns wherein the yarn is made into a substrate having tranvsersely laid yarns, foamed dye is placed on the substrate, and the foamed substrate is impacted to cause penetration of the foam through the substrate. The apparatus may include a hammer-like impactor acting against an anvil for impacting the foamed substrate, and the impactor may be driven by mechanical arrangements, or by ultrasonic sound drive means. The apparatus may also include impacting rollers wherein the diameter of the roller is small, and the rate of rotation high, so the rate of increase in pressure on the substrate by the rollers is equal to impaction.
