Abstract
A method for processing a polyalkylene benzenedicarboxylate material includes subjecting a polyalkylene benzenedicarboxylate material to an immersion treatment with an immersion liquid including ethylene glycol, so as to obtain an immersed polyester material, and subjecting the immersed polyester material to a disintegration treatment to obtain a disintegrated polyester material. The immersed polyester material has crystallinity higher than that of the polyalkylene benzenedicarboxylate material.
