Method and apparatus for dyeing garments

An apparatus for dyeing dye-absorbent material, the apparatus comprising:

• a dye injection system configured to dispense concentrated liquid dye;
• a dyeing machine comprising a dyeing chamber configured for dyeing at least one dye-absorbent material in a dyebath, wherein the dyebath comprises the concentrated liquid dye received from the dye injection system and a volume of solvent;
• and
• a controller in communication with the dye injection system and the dyeing machine, wherein the controller is configured to:
• receive at least one material parameter corresponding to the at least one dye-absorbent material;
• based at least in part on the at least one received material parameter, cause the dye injection system to dispense a volume of concentrated liquid dye that contains an amount of dyestuff that can be substantially absorbed by the at least one dye-absorbent material;
• and
• cause the dyeing machine to execute a dye cycle such that substantially all of the dyestuff in the dispensed volume of concentrated liquid dye is absorbed by the at least one dye-absorbent material within the dyeing chamber;
• wherein the dyeing machine is configured to maintain at least a portion of the volume of solvent within a substantially closed-loop system for reuse in a subsequent dye cycle.
