Abstract: In dyeing processes the velocity of the dyeing liquid when passing through the material to be treated is important. The forcing of the liquid through the material imposes a heavy load upon the pump, and it has been found, that a more uniform dyeing is obtained with less expenditure of power if the dyeing apparatus is provided with at least two compartments into which the bulk of material to be treated may be placed in two smaller batches. The two compartments are alternatingly connected to the pump, in such a manner that one compartment will always contain flowing liquid while the other contains liquid at rest. The term for switching over may be selected with respect to the material to be treated and the type of dyestuff, but each period of activity should be sufficient long to permit a complete substitution of the liquid within the compartment.
