Abstract: A method of recycling polyester fabric includes following steps. A polyester fabric including polyethylene terephthalate and dyes is provided. An extraction process including using ethylene glycol as an extraction solvent, immersing the polyester fabric in the extraction solvent, and extracting under a temperature of 80° C. to 180° C. is performed to remove the dyes from the polyester fabric. A depolymerization process including using a chemical depolymerization solution to depolymerize the polyester fabric treated with the extraction process to obtain a product including BHET is performed. The chemical depolymerization solution is ethylene glycol. A purification process is performed to remove impurities of the product obtained by the depolymerization process and to obtain a purified BHET. A solvent recycling process is performed. The solvent recycling process includes collecting waste solutions of the extraction process and the depolymerization process, and recycling ethylene glycol in the waste solutions by a distillation separating system.
