Abstract

본 발명은 사절 및 방사작업성이 현저하게 향상되어 원사의 생산성이 높아진 폴리에스테르를 제조하기 위한 것으로서, 폴리에스테르를 제조함에 있어서, 중합 전 옥은 중합 중간에 테레프탈산 100중량부에 대해 이소프탈산 0.01~10중량부, 칼슘아세테이트, 마그네슘아세테이트, 마그네슘스테아레이트 또는 마그네슘옥사이드 중에서 선택된 1종의 화합물 0.001~0.5중량부, 디부틸 틴말레이에이트 0.005~0.05중량부 및 안티몬계 촉매 0.01~0.08중량부를 투입하여 중합함을 특징으로 한다.The present invention is for producing a polyester with a markedly improved trimming and spinning workability, which increases yarn productivity. In preparing the polyester, jade before polymerization is 0.01 to isophthalic acid from 0.01 to 100 parts by weight of terephthalic acid in the middle of the polymerization. 10 parts by weight, 0.001 to 0.5 parts by weight of a compound selected from calcium acetate, magnesium acetate, magnesium stearate or magnesium oxide, 0.005 to 0.05 parts by weight of dibutyl tin maleate and 0.01 to 0.08 parts by weight of an antimony catalyst were added. It is characterized by.
