Reconstruction of cotton-polyester blended fabric

Abstract

Through this article, as the procedures of added glycol (EG) catalyzer in reaction system; After depolymerize the polyester fibre(PET) of the waste cotton-polyester blended fabric to alcoholysis as bis-hydroxyethyl terephthalate (BHET), and then separate it with solid cotton and liquid BHET through the Solid-liquid separation device. To added separation product (BHET) and catalyzer in the Polycondensation reaction system to polycondensation BHET as reconstituted Polyethylene terephthalate (PET). The experimental results indicated that separated cotton and reconstituted PET meet the requirement of recycling.
