Title:
ULTRAVIOLET-RESISTANT POLYESTER FIBER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/242168
Kind Code:
A1
Abstract:
Provided are an ultraviolet-resistant polyester fiber and a preparation method therefor. The preparation method comprises: firstly, preparing a chelating borate coupling agent containing a dicarboxyl functional group by using triisopropyl borate, 2-hydroxy diacid and a diol as raw materials, then modifying nano-rare earth cerium oxide by using the chelating borate coupling agent containing a dicarboxyl functional group to obtain a modified nano-rare earth cerium oxide, and subjecting the modified nano-rare earth cerium oxide, terephthalic acid and ethylene glycol to in-situ polymerization, and processing same to obtain the ultraviolet-resistant polyester fiber. The obtained polyester fiber has more lasting, more stable and excellent ultraviolet-resistance.
