Abstract: A method for decolorization of polyester fabrics is provided. The method for decolorization of polyester fabrics includes putting polyester fabrics into an extraction cell. The method for decolorization of polyester fabrics also includes making a supercritical fluid and a co-solvent flow into the extraction cell. The method for decolorization of polyester fabrics further includes adjusting the temperature in the extraction cell to be greater than or equal to the glass transition temperature of the polyester fabrics, so that the supercritical fluid and the co-solvent perform a decolorization reaction on the polyester fabrics. Moreover, the method for decolorization of polyester fabrics includes making the supercritical fluid and the co-solvent flow out of the extraction cell. The method for decolorization of polyester fabrics also includes taking the polyester fabrics out of the extraction cell.

Abstract: A method for decolorizing polyester fabric and a polyester fabric are provided. The method for decolorizing polyester fabric includes providing a dye-attached polyester fabric. The dye-attached polyester fabric is immersed in a first solution, obtaining a treated polyester fabric. The treated polyester fabric is immersed in a second solution, to obtain a decolorized polyester fabric. The first solution includes water, a first swelling agent and a solubility promoter. The second solution includes water, a second swelling agent, and an auxiliary swelling agent.
