염색성이 개선된 폴리우레탄 또는 폴리우레탄우레아 탄성사 및 이의 제조방법{Elastic fiber having improved dying property, and method of manufacturing the same}TECHNICAL FIELD [0001] The present invention relates to a polyurethane or polyurethane-urea elastic yarn having improved dyability and a method for producing the same.

본 발명은 염색성이 개선된 폴리우레탄 또는 폴리우레탄우레아 탄성사 및 이의 제조방법에 관한 것으로, 보다 상세하게는 반응성 염료에 대한 염색성이 개선된 폴리우레탄 또는 폴리우레탄우레아 탄성사 및 이의 제조방법에 관한 것이다.The present invention relates to a polyurethane or polyurethane-urea elastic yarn having improved dyeability and a method for producing the same. More particularly, the present invention relates to a polyurethane or polyurethane-urea elastic yarn having improved dyeability with respect to a reactive dye and a method for producing the same.

탄성 특성을 갖는 폴리우레탄 섬유는 섬유 산업에 있어서 광범위하게 이용되고 있다. ‘스판덱스’ 섬유는 이러한 탄성 섬유를 의미하는 일반적인 용어로 사용되고 있으며, 보통 섬유를 형성하는 구조중 폴리우레탄 결합이 85 %이상인 합성 섬유를 지칭한다.Polyurethane fibers having elastic properties are widely used in the textile industry. 'Spandex' fibers are used as generic terms to refer to these elastic fibers, and generally refers to synthetic fibers having a polyurethane bond content of at least 85%.

이러한 폴리우레탄 섬유는, 일반적으로 고분자량의 디올 화합물인 폴리올과 과량의 디이소시아네이트 화합물을 반응시켜 폴리올의 양 말단에 이소시아네이트기를 가지는 예비 중합체(Prepolymer)를 얻는 1차 중합반응과, 상기 예비 중합체를 적절한 용매에 용해시킨 후 그 용액에 디아민계 또는 디올계 쇄연장제를 첨가하여 반응시키는 2차 중합반응을 거쳐 제조된다.Such a polyurethane fiber generally comprises a primary polymerization reaction in which a polyol which is a high molecular weight diol compound is reacted with an excessive diisocyanate compound to obtain a prepolymer having isocyanate groups at both ends of the polyol, Followed by a secondary polymerization reaction in which a diamine-based or diol-based chain extender is added to the solution.

폴리우레탄 섬유는 용도에 따라 아크릴, 울, 면, 견 등과 같은 다른 여러 가지 섬유와 조합되어 사용될 수 있으며, 보통 속옷, 수영복 및 스타킹등 탄성을 필요로 하는 목적으로 사용되어 왔다.Polyurethane fibers can be used in combination with various other fibers such as acrylic, wool, cotton, silk, etc., depending on the application, and have been used for purposes requiring elasticity such as underwear, swimwear and stockings.

이러한 탄성을 갖는 고유의 특징 때문에 폴리우레탄 섬유는 다양한 용도로 활발하게 사용되고 있으며, 그 용도의 확대에 따라 기존의 폴리우레탄 섬유에 새로운 부가적인 특성이 계속하여 요구되고 있다. 지금까지 내열성 및 탄성 회복력이 더욱 강화된 폴리우레탄 섬유가 다수 개발되었으며, 최근에는 높은 열세트성을 갖는 폴리우레탄 섬유 및 염색성이 향상된 폴리우레탄 섬유에 대한 수요도 점차 증가하고 있다.Because of its inherent characteristics of elasticity, polyurethane fibers are actively used for various purposes, and with the expansion of their applications, new additional characteristics have been continuously required in existing polyurethane fibers. Up to now, many polyurethane fibers have been developed that have enhanced heat resistance and resilience, and in recent years there has been a growing demand for polyurethane fibers with high heat setting properties and polyurethane fibers with improved dyeability.

폴리우레탄 섬유는 일반적으로 염색성이 좋지 못한 문제점을 가지고 있는데, 산성 염료에 대한 염색성을 향상시키기 위한 일반적인 기술로는 아크릴계 염착증진제 또는 우레탄계 염착증진제를 사용하거나, 제 1 급 혹은 제 2 급 아민을 가지는 고분자를 사용하는 방법 등이 있다.Polyurethane fibers generally have poor dyeability. Typical techniques for improving the dyeability of acid dyes include the use of an acrylic based adhesion promoter or a urethane based adhesion promoter, or a polymer having a primary or secondary amine And the like.

그러나, 상기와 같은 기술로 산성 염료에 대한 폴리우레탄 섬유의 염색성은 개선 될 수 있으나, 반응성 염료와의 결합에 의해 반응성 염료에 대한 폴리우레탄섬유의 염색성을 향상시키는 종래의 기술은 없는 상황이다.However, although the dyeability of the polyurethane fiber to the acid dye can be improved by the above-described technique, there is no conventional technique for improving the dyeability of the polyurethane fiber to the reactive dye by bonding with the reactive dye.
