Abstract

The invention discloses a method for improving the level-dyeing property of fabric in supercritical carbon dioxide fluid and a device thereof. The method adopts special seamless warp beam which consists of an inner layer and an outer layer is adopted, a seamless woven wrapper of a cylindrical net shape is sleeved outside the outermost layer of wound fabric, and process parameters such as the time ratio between fluid circulation and static dyeing, and the like are controlled reasonably, thereby realizing the uniform dyeing of piece fabric in the supercritical carbon dioxide fluid. Since the method adopts the warp shaft mode with a reasonable structure, the fabric winding way and the process condition, the supercritical fluid containing a soluble dye can penetrate through the wound fabric uniformly, thereby reducing the non-uniform pressure loss in the fluid flow during circulation, the sudden change of the fluid path and the unevenness of the fluid circulation, and improving the uniform dyeing effect on the piece fabric. The technical method of the invention has the advantages of simple equipment and process, convenient operation, high efficiency, energy conservation and emission reduction.

Description

technical field [0001] The invention relates to a method and a device for improving the level dyeing property of a fabric in a supercritical carbon dioxide fluid, in particular to a method for improving the level dyeing property of a piece-dyed fabric in a supercritical carbon dioxide fluid, belonging to the technical field of textile dyeing and finishing. Background technique [0002] Supercritical carbon dioxide fluid is a safe, environmentally friendly and green fluid medium. Using it to replace traditional water baths for anhydrous dyeing of fabrics can completely realize green, environmentally friendly and clean production, and has the advantages of energy saving and consumption reduction. The critical carbon dioxide fluid dyeing technology is a revolutionary technology in the textile printing and dyeing industry, which is of great significance to change the current situation of the traditional textile printing and dyeing industry, such as high water consumption, high en...
