Abstract of the Disclosure A process is disclosed for the rapid, continuous and waterless dyeing of textile and plastic materials in which the dyestuff is dissolved, suspended or dispersed in a high boiling solvent, such as glycol or glycol ether, for carrying out the dyeing step per se, after which the dyed textile or plastic material (after cooling if desired) is subjected to a washing with a low boiling liquid such as methanol or ethanol (preferable the former) or a chlorinated hydrocarbon solvent, and subsequently dried. The entire series of the operations is carried out under nonaqueous or substantially nonaqueous conditions with the complete or substantially complete recovery and recycling of the used dye- stuff, the used high boiling solvent, and the used low boiling wash liquid. In this way the entire operation is conducted in a relatively inexpensive fashion and in a completely or substantially completely closed cyclic system with essentially complete recovery and reuse of the treating liquids so that not only is the cost of the overall operation liquids minimized, but also without any need for pollution of natural water resources such as rivers and wells such as has in the past taken place to a more or less serious extant where effluents of a substantially aqueous nature but containing serious amounts of polluting substances were discharged into rivers and the like thereby creating environmental problems.
