Abstract: The disclosure provides a chemical recycling method for polyester fabrics, which includes the following steps. The polyester fabric is extracted using a composite solvent and filtered to obtain a decolored polyester fabric. The composite solvent contains alcohol ether and phenyl ether, and the decolored polyester fabric contains the composite solvent. Ethylene glycol is then added to the decolored polyester fabric to depolymerize into ethylene terephthalate monomers.
