Abstract
Disclosed is a method for recycling a polyester blend fabric. The method includes: treating a polyester-containing raw material to be treated, subjecting a resulting treated polyester-containing raw material to polyester degradation at 40° C. to 120° C. for 0.5 h to 8 h in the presence of a catalyst to achieve complete depolymerization, separating out and recovering a polyester component, and reutilizing the polyester component and other blend components.
