摘要

The second part of this work is devoted to the analysis of the swelling process, i.e., phase separation of swelling bath, solubility properties of coated fabrics in swelling bath, and swelling extent of each component in coated fabrics. A variety of analytical methods was used to characterize the separation sol- vent, the amount and removeability of the glue, the changes in the chemical and physical properties of the PVC and PET polymers during the processes, and the extent of recovery of the plasticizer. Initial recovery PET fabrics (scraps) were fur- ther treated with removal of glue from the fabric surface in a dimethyl formamide (DMF) solution.
