Claims (5)

에틸렌 글리콜과 테레프탈산 또는 디메틸테레프탈레이트를 반응시켜 폴리에스터를 제조할때 테레프탈산 또는 디메틸 테페트탈레이트 이외의 방향족 디 카복실산 또는 그 에스터 형성유도체 및 아래 일반식(1)로 표시되는 치환된 다관능성 카복실산을 첨가하여 폴리에스터 공중합체를 제조함을 특징으로 하여 방사 연신하는 이염성 폴리에스터 섬유의 제조 방법이다.When preparing polyester by reacting ethylene glycol with terephthalic acid or dimethyl terephthalate, aromatic dicarboxylic acid or ester forming derivative thereof other than terephthalic acid or dimethyl terephthalate and substituted polyfunctional carboxylic acid represented by the general formula (1) below It is a manufacturing method of the dibasic polyester fiber spin-stretched characterized by adding and manufacturing a polyester copolymer. (여기서 A는 2-4개의 탄소원자를 갖는 알킬렌기(Where A is an alkylene group having 2-4 carbon atoms) R은 수소 또는 1-3개의 탄소원자를 갖는 알킬기R is hydrogen or an alkyl group having 1-3 carbon atoms X는 페닐렌기 또는 카보닐기X is phenylene group or carbonyl group Y는 히드록시기 또는 1-3개의 탄소원자를 갖는 알콕시드기Y is a hydroxy group or an alkoxide group having 1-3 carbon atoms P는 2-3인 정수P is an integer of 2-3 n은 4-35인 정수를 나타낸다.)n represents an integer of 4-35.) 제1항에 있어서 방향족 디 카복실산은 테레프탈산 또는 디메틸테레프탈레이트 이외의 것을 사용하는 것이 좋으며, 프탈산, 무수프탈산, 이소프탈산, 나프타린의 디 카복실산, 디페닐디카복실산을 사용함을 특징으로 한다.The aromatic dicarboxylic acid according to claim 1 is preferably used other than terephthalic acid or dimethyl terephthalate, and is characterized in that phthalic acid, phthalic anhydride, isophthalic acid, dicarboxylic acid of naphthaline, and diphenyldicarboxylic acid are used. 제1항에 있어서 일반식(1)의 첨가시기는 에스터 반응 또는 에스터 교환반응이 개시되기 전이나, 중합반응이 개시되기 전에 첨가함을 특징으로 한다.The addition time of general formula (1) is characterized in that it is added before the ester reaction or the transesterification reaction is started or before the polymerization reaction is started. 제1항 제2항 및 제3항에 있어서 테레프탈산 또는 디메틸테레프탈레이트 이외의 방향족의 디 카복실 산 또는 그 에스터 형성유도체 및 일반식(1)의 첨가량은 폴리에스터 중량에 대하여 각각 0.03-10%, 0.08-15% 범위내에서 첨가한다.The amount of aromatic dicarboxylic acid other than terephthalic acid or dimethyl terephthalate or its ester-forming derivative and general formula (1) according to claim 1 or 2 is 0.03-10% and 0.08, respectively, based on the weight of polyester. Add in the range -15%. 제4항에 있어서 특히 에스터반응 또는 에스터 교환 반응이 시작되기 전에 각각 0.1-8%, 1-10%범위내에서 첨가하는 것이 더욱 바람직하다.According to claim 4, it is particularly preferable to add within the range of 0.1-8% and 1-10% before the ester reaction or the ester exchange reaction is started. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
