Abstract
A device for color-fixing processing on textiles includes a supercritical carbon dioxide fluid unit, a fixing liquid storage tank (2) and a fixing reactor (9). The fixing liquid storage tank (2) is below the fixing reactor (9) and sealed connected by a connecting device (6). The fixing liquid storage tank (2) has a cylindrical cavity in which a fluid distributor (4) is mounted. The fluid distributor (4) is composed of several interconnected pipes which bend down with the nozzles downward, and one of the pipes is used as circulated fluid inlet (1) connected with the supercritical carbon dioxide fluid unit, and the rest of the pipes are used as circulated fluid outlets.
