INTEGRATED WATERLESS SCOURING, BLEACHING, AND DYEING DEVICE USING SUPERCRITICAL CARBON DIOXIDE FLUID

摘要

The present invention relates to the field of textiles, and provides an integrated waterless scouring, bleaching, and dyeing device using a supercritical carbon dioxide fluid. The integrated waterless scouring, bleaching, and dyeing device using a supercritical carbon dioxide fluid provided by the present invention comprises a co-solvent system, a scouring, bleaching, and dyeing system, and a separation and recovery system which are uniquely designed. By means of uniform dispersion and dissolution of a co-solvent, a dye, and carbon dioxide, scouring, bleaching, and dyeing of jute fiber roving can be implemented. In addition, the integrated waterless scouring, bleaching, and dyeing device using a supercritical carbon dioxide fluid integrates the three functions of scouring, bleaching, and dyeing, can complete the scouring, bleaching, and dyeing procedures in one step, and is highly efficient, thereby resolving the problems of high pollution and high energy consumption in the scouring, bleaching, and dyeing procedures of jute fibers.
