摘要： Provided is a chemically-recycled PET fiber with reduced degradation and superior strength and durability, and rubber-fiber composite products, such as tires, using the chemically-recycled PET fiber. The chemically-recycled PET fiber is made by polymerizing a raw material containing at least one of a monomer and an intermediate that are obtained by depolymerization of a PET product, the monomer including terephthalic acid (TPA) and/or dimethyl terephthalate (DMT) and the intermediate including bis(2-hydroxyethyl) terephthalate (BHET). The chemically-recycled PET fiber has a carboxyl end group (CEG) concentration of 15 eq/ton or less and a degree of crystallinity of 40% or more.

摘要： The polymerization raw material comprising recycled bis(2-hydroxyethyl) terephthalate in which the contents of acetate-based ester compounds and diethylene glycol ester compounds are adjusted to specific levels are excellent in purity and quality, as well as the problem that thermal resistance characteristics deteriorate in the polymerization of a polymer from the recycled monomer does not occur.

摘要： The present invention relates to a method for producing bis-2-hydroxyethyl terephthalate, the method comprising the steps of: (1) adding a waste polyester raw material into a co-extruder to obtain a co-extrudate; (2) adding the co-extrudate into a reactor with an agitation shaft and depolymerizing same to obtain a first reaction product; (3) adding the first reaction product into a first continuous stirred tank reactor and depolymerizing same to obtain a second reaction product; and (4) adding the second reaction product into a second continuous stirred tank reactor and depolymerizing same to obtain a third reaction product.
