SUPERCRITICAL CARBON DIOXIDE DYEING BATH FOR IMPROVEMENT OF LEVEL DYEING

摘要

The present invention relates to a supercritical carbon dioxide dyeing bath for the improvement of level dyeing, which comprises the following: a dyeing chamber in a container form having an opening and closing cover on one side; a dyeing beam installed on the inner center of the dyeing chamber toward the axis direction, and having a plurality of spraying holes along the circumferential direction or the axis direction for spraying supercritical carbon dioxide with a dye dissolved in the outer perimeter into the dyeing chamber; and a circulation pump circulating the supercritical carbon dioxide inside the dyeing chamber toward the dyeing beam. A plurality of inlets and outlets are arranged asymmetrically on the outer perimeter of the dyeing chamber, so the supercritical carbon dioxide including the dye sprayed through the dyeing beam cam uniformly flow and the dyeing can be uniformly performed on the entire portion of a fabric.
