摘要： A device for colour-fixing processing on textiles includes a system of supercritical carbon dioxide fluid, 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 bending down with the nozzles downward, and one of the pipes is used as circulated fluid inlet (1) connected with the supercritical carbon dioxide fluid system, and the rest pipes are used as circulated fluid outlets.

摘要： The present invention relates to a phase-transfer catalytic colour fixation processing method for a textile. The processing method comprises the following steps: dyeing a natural fibre textile in a supercritical carbon dioxide fluid waterless dyeing system using a disperse reactive dye, and then realizing a reaction fixation of the dye on the fibres using a phase transfer catalyst in the supercritical carbon dioxide fluid. Since the method utilizes the action of the phase-transfer catalyst in the colour fixation stage, an ionized colour fixation reaction accelerator and the like is effectively transferred to the supercritical carbon dioxide colour fixation fluid and solid-phase fibres, thus improving the nucleophilic reactivity of the functional group on the fibres, achieving the colour fixation reaction between the fibres and the dye in the supercritical carbon dioxide fluid conditions, and improving the colour fixation efficiency of the dye on the fibres. The technical method provided by the invention realizes the reaction fixation of the dye on the fibres in hydrophobic fluid conditions, and has the advantages of a high colour fixation efficiency, a simple process, being green and environmentally friendly and the like.
