Abstract: A method for degumming and decolorizing polyester fabrics is provided. The method includes the following steps. A first polyester fabric attached with a dye and a gum-film or treatment agent is provided. The gum-film or treatment agent in the first polyester fabric is stripped through a combined formulation of an alkaline aqueous solution and a catalyst to obtain a second polyester fabric. Then, the second polyester fabric is decolorized by a combination of a chemical reduction method and a chemical oxidation method to obtain a third polyester fabric.
