description A method and an integrated system for dyeing synthetic, natural, and blended textiles in the form of fabrics, yarns, and garments are provided. The integrated system includes a first pressurizing pump for pressurizing liquefied CO2to supercritical CO2(Sc-CO2); a second pressurizing pump for pressurizing CO2to liquefied CO2; a liquefied CO2storage vessel for storing the liquefied CO2and the separated liquefied CO2from the one or more cyclone separators; a heater for heating the Sc-CO2; a dyestuff vessel for mixing a dyestuff and the Sc-CO2to obtain Sc-CO2-mixed dyestuff; a dyeing vessel for dyeing the textile by circulating the Sc-CO2and the Sc-CO2-mixed dyestuff between the dyeing vessel and the dyestuff vessel; and one or more cyclone separators for removing the dyestuff from the Sc-CO2-mixed dyestuff to obtain separated liquefied CO2.
