发明名称 Separation of contaminants from polyester materials
摘要 The present invention is generally directed to a process for separating and recovering post-consumer polyester from various contaminant materials. The invention can be utilized to separate post-consumer polyester from various contaminants including glass, dirt, paper, metal, glue, dye, and the like. The disclosed process includes several stages including a preparation stage, in which a portion of the contaminants can be removed from the polyester, as well as a reaction stage, in which a portion of the polyester can be saponified and contaminants can be physically separated from the polyester. In addition, during the reaction stage, certain hard-to-separate contaminants, such as aluminum and polyvinyl chloride, can react to a form more easily separable from the polyester.
