Method for colour-fixing processing of textile and device therefor

A device for colour-fixing processing on textiles, characterized in that:

• it comprises a system of supercritical carbon dioxide fluid, a fixing liquid storage tank (2) and a fixing reactor (9), said fixing liquid storage tank (2) is below said fixing reactor (9) and sealed connected by a connecting device (6), said fixing liquid storage tank (2) has a cylindrical cavity in which a fluid distributor (4) is mounted, said fluid distributor (4) is composed of several interconnected pipes which bending down with the nozzles downward, and one of the pipes is used as circulated fluid inlet (1) connected with said supercritical carbon dioxide fluid system, and the rest pipes are used as circulated fluid outlets, said fixing reactor (9) has a cylindrical cavity, with a circulated fluid outlet (11) on the top and connected with said supercritical carbon dioxide fluid system;
• a porous filter (5) is installed at the bottom of the reactor (9), and the lower part of a fluid diversion cover (7) is horn shaped, covering at the top of the porous filter (5), and the top port of the fluid diversion cover (7) is connected with the opposed port of textile winding shaft (8), said textile winding shaft (8) is a cylindrical hollow shaft, whose top port is closed and holes are set on the cylinder.
