Recycling polyester/cotton blend fabrics by dissolving polyester

摘要

A process is described for recycling polyester and cotton blend fabrics by separating the polyester from the cotton fabric. The novel process to recycle the polyester/cotton blend fabrics includes the steps of (a) providing a polyester and cotton blend fabric; (b) charging said blend into a sulfone solvent; (c) dissolving the polyester in the sulfone solvent; (d) separating the dissolved polyester and sulfone solvent solution from the cotton fabric; (e) filtering the cotton to obtain isolated, cotton fabric.
