Recycled raw material and method of manufacturing the same

Abstract

The present invention relates to a process for preparing a recycled raw material, which comprises depolymerizing a reaction raw material comprising a main raw material and an auxiliary raw material, wherein the main raw material comprises waste polyester, and the auxiliary raw material comprises at least one compound selected from the group consisting of monohydroxyethyl terephthalate (MHET), bis(2-hydroxyethyl) isophthalate (BHEI), 2-hydroxyethyl[2-(2-hydroxyethoxy)ethyl] terephthalate (DEG-ester-1), bis[2-(2-hydroxyethoxy)ethyl]benzene-1,4-dicarboxylate (DEG-ester-2), 2-hydroxyethyl(2-acetoxyethyl) terephthalate (HA-ester), and 2-hydroxyethylmethyl terephthalate (ME-ester), and to a recycled raw material prepared thereby.
