Document Type and Number:
WIPO Patent Application WO/2023/013330
Kind Code:
A1
Abstract:
Provided are chemically-recycled PET fibers in which degradation is suppressed and having excellent strength and durability, and rubber-fiber composite products such as tire and the like, that use said chemically-recycled PET fibers. The chemically-recycled PET fibers of the present invention are characterized by having as raw material at least one compound selected from among terephthalic acid (TPA), dimethyl terephthalate (DMT), and bis (2-hydroxyethyl) terephthalate (BHET), that are obtained by depolymerization of a PET product.
