1. A method for processing a polyalkylene benzenedicarboxylate material, comprising:
subjecting a polyalkylene benzenedicarboxylate material to an immersion treatment with an immersion liquid including ethylene glycol, so as to obtain an immersed polyester material, the immersed polyester material having crystallinity higher than that of the poly alkylene benzenedicarboxylate material; and
subjecting the immersed polyester material to a disintegration treatment to obtain a disintegrated polyester material.
