Abstract

본 발명은 폴리에스테르 고분자 내에 자외선 차단성능이 있는 벤조트리아졸계 자외선 차단 물질을 혼입하여 제사 공정 및 후가공에서의 공정문제점을 유발하지 않으면서 기존의 폴리에스테르 섬유 특성을 그대로 유지하고 자외선 차단성능이 우수한 폴리에스테르 중합체를 제조하는 방법에 관한 것이다.The present invention incorporates a benzotriazole-based UV-blocking material having UV-blocking properties in the polyester polymer to maintain the existing polyester fiber properties without causing process problems in the weaving process and post-processing, and has excellent UV-blocking performance. It relates to a process for preparing an ester polymer.
