摘要

The polyester in the base fabrics (PET) and the polyvinyl chloride coating (PVC) along with plasticizers and adhesive/glue were separated from a commercial coated fabric by a scheme of chopping, grinding, and extracting with a selected preferred aqueous MEK solution. A novel recovering method called swelling method is introduced to separate and reuse waste PVC coated PET fab- tics. In comparison with other recycling techniques, the swelling method is a sim- ple procedure with minimal environmental impact. The selection of the swelling agent of methylethyl ketone (MEK) was made after an analysis of the physical and chemical properties of several chemicals. Phase separation was found in the MEK/water system that serves as swelling bath. The two phases exist over a wide concentration range. The behavior of the swelling system and the swelling proper- ties of recovered components were investigated by parameters, such as refractive index, swelling degree, and the average particle size of recovered PVC.
