SUPERCRITICAL CARBON DIOXIDE MULTI-STAGE DYE MIXING CHAMBER USING PULSE

WIPO Patent Application WO/2018/128251

A1

The present invention relates to a supercritical carbon dioxide multi-stage dye mixing chamber using a pulse. The supercritical carbon dioxide multi-stage dye mixing chamber using a pulse comprises: a multi-stage receptacle body provided with an inlet port, for supercritical carbon dioxide to flow in, on the upper part and provided with an outlet port, for a mixture of the supercritical carbon dioxide and dye to flow out, on the lower part; a dye receptacle provided inside the receptacle body and having the dye to be mixed with the supercritical carbon dioxide filled therein; a pulse generating means for providing a pulse to the supercritical carbon dioxide supplied to the receptacle body; and a vortex generating means provided on the inlet port of the receptacle body and for providing a vortex to the supercritical carbon dioxide flowing into the receptacle body. By means of the technical constituents, the dye contained in the dye receptacle can completely be dissolved, the supercritical carbon dioxide dyeing efficiency can be enhanced by means of the improved mixing of the dye, and the marketability of a supercritical carbon dioxide dyeing machine can greatly be enhanced.
