Title:
POLYAMIDE FIBER HAVING ANTI-ULTRAVIOLET PERFORMANCE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/241979
Kind Code:
A1
Abstract:
The present application relates to the technical field of polyamide fiber materials, and in particular, discloses a polyamide fiber having anti-ultraviolet performance and a preparation method therefor. Firstly, triisopropyl borate, 2-amino-3-hydracrylic acid, and dihydric alcohol serve as raw materials to prepare a bifunctional group chelating type borate coupling agent having amino and carboxyl; a nano rare earth oxide is modified by using the synthesized coupling agent; then in-situ polymerization is performed on the modified nano rare earth oxide and caprolactam to prepare a nylon resin containing the nano rare earth oxide; and finally, spinning is performed to prepare the polyamide fiber. The obtained polyamide fiber has more lasting and more stable and excellent anti-ultraviolet performance.
