Title: SUPERCRITICAL CARBON DIOXIDE DYEING BATH FOR ENHANCED LEVEL DYEING
Abstract:
The present invention relates to a supercritical carbon dioxide dyeing bath for enhanced level dyeing. The present invention comprises: a barrel-shaped dyeing chamber having an opening and closing lid on one side; a dyeing beam provided in the center inside the dyeing chamber and in the axial direction and having on the outer periphery a plurality of injection holes, which are for injecting supercritical carbon dioxide having dye dissolved therein into the dyeing chamber, in the circumferential direction and the axial direction; and a circulation pump for circulating the supercritical carbon dioxide in the dyeing chamber toward the dyeing beam. A plurality of inlet/outlet ports are asymmetrically disposed in the circumferential direction on the outer periphery of the dyeing chamber. By means of the technical constituents, the present invention enables a uniform flow of the dye-containing supercritical carbon dioxide being injected by means of the dyeing beam and thus enables uniform dyeing of the overall part of a fabric.
