Claim:
1. A phase-transfer catalytic colour fixation processing method for textile, characterized in that it comprises the following steps: (1) dry-dyeing a textile with disperse reactive dyes in supercritical carbon dioxide fluid under waterless condition; (2) putting the textile in a phase-transfer catalytic fixation device, taking phase-transfer catalyst as the carrier of circulated supercritical carbon dioxide fluid, transporting the ionized fixing catalytic alkaline substance from aqueous phase to hydrophobic supercritical carbon dioxide fluid phase, getting full contact with functional groups on fibres, resulting in the fixing catalytic reaction with disperse reactive dyes, Wherein said ionized fixing catalytic alkaline substance is sodium hydroxide, sodium carbonate, sodium phosphate, or substances that can produce hydroxyl by hydrolysis or thermal decomposition in the environment with a small amount of water, the concentration of said fixing catalytic alkaline substance is 0.1 g/L˜20g/L, and said phase-transfer catalyst is perfluorooctyl quaternary ammonium salt, or quaternary ammonium salt with C
