Abstract: Provided herein is a method for decolorizing textile materials under hydrothermal conditions using dye adsorbent materials. The process is non-toxic and environmentally friendly, and the adsorbent materials can be repeatedly used. The textile materials are textile materials dyeable with disperse dyes. Further provided is a system for decolorizing textile materials. The decolorization system is designed to allow the adsorbent materials to react with the textile materials in a contact manner and a non-contact manner.
