ABSTRACT:
A process of producing purified fabric substantially free of polyolefin contamination comprising the steps of supplying a fabric containing polyolefin contamination, selecting a solvent which selectively solubilizes the polyolefin wherein said solvent solubilizes polyolefin at temperatures and pressures that do not degrade the fabric, treating the fabric with said selected solvent to solubilize the polyolefin and removing the solvent containing solubilized polyolefin contamination and recovering purified fabric.
