| abstract | According to the present invention, an oligomer solution is prepared by depolymerizing waste polyester and ethylene glycol using a depolymerization catalyst, contacting the oligomer solution with an ion exchange resin to remove the catalyst in the oligomer solution, and then passing the oligomer solution having the catalyst removed through a decolorant. To remove colored materials such as colorants in the oligomer solution, and to distill the ethylene glycol in the purified oligomer solution at a pressure of 1 to 760 TORR and a temperature of 100 to 250 ° C, followed by condensation polymerization to recover the polyester. It is about. The recycled polyester produced by the present invention is excellent in color, and is easy to remove foreign matter in the waste polyester recovered after consumer use, it is possible to manufacture fine-seam yarn, functional yarn and the like. |
