Alkali Hydrolysis of Polyester Fabric under Ultra-High Pressure

Abstract

The process of alkaline hydrolysis of polyester (PET) fabric under high-pressure conditions of over 100 MPa was examined. The decomposition of the PET fabric was accelerated with increased pressure. The addition of surfactant also enhanced the reaction rate when the concentration was more than 1.0 g/l. At high surfactant concentrations, the acceleration effect plateaued. The activation volume hardly changed with the concentration of surfactant.
