Abstract

An system for anhydrous boiling, bleaching and dyeing using a supercritical carbon dioxide fluid and belongs to the field of textile. The system for anhydrous boiling, bleaching and dyeing of a supercritical carbon dioxide fluid provided by the present invention is provided with a co-solvent system, a boiling, bleaching and dyeing system, and a separation and recovery system which are specially designed. By means of uniform dispersion and dissolution of a co-solvent, dyestuff and carbon dioxide, boiling, bleaching and dyeing production of jute fiber rough yarn can be achieved; meanwhile, the system for anhydrous boiling, bleaching and dyeing using a supercritical carbon dioxide fluid integrates the three functions of boiling, bleaching and dyeing, which can complete the boiling, bleaching and dyeing procedures in one step, and has the characteristic of high-efficiency, thus solving the problems of high contamination and high energy consumption of the jute fiber boiling, bleaching and dyeing procedures.
