LEACHING CONTAMINANTS FROM POST-CONSUMER POLYESTER
摘要
<p>A novel technique to treat post-consumer polyester for reuse in food-contact applications is described. The process comprises contacting contaminated post consumer polyester flake with at least one extraction solvent which is soluble in said contaminated flake at a temperature sufficient to allow rapid diffusion of contaminants from said polyester flake; and removing said extraction solvent containing said contaminants from said polyester flake.</p>
