'산업혁명' 이라고 불리는 폴리우레탄우레아 섬유 즉, 스판덱스는 스포츠웨어와 이너웨어, 스타킹 등, 여러 방면으로 사용 되어지고 있다. 높은 탄성과 내마모성, 내화학성, 내저온성, 내노화성, 내유성 등의 장점을 활용하여 적용분야가 더욱 다양해지고 있다. 낮은 내열성, 염색성과 열과 빛 등에 의한 황변 등이 단점 또한 있지만, 최근 까지도 이러한 단점들을 보완하기 위해 폴리머의 개선, 폴리머 방사법의 개발, 첨가제의 개발 등, 활발히 연구 하고 있다. 본 연구에서는 폴리우레탄우레아의 낮은 염색성을 개선 하기 위한 첨가제 중 하나 인, 우레탄계 염색향상제에 대한 중합을 연구 진행 하였다. 우레탄계 염색향상제의 원료 물질인 2-(diethylamino)ethyl methacrylate를 효율적이고 경제적인 제조 방법을 위해 반응시간, 반응물, 촉매에 종류에 따른 연구를 진행하였다. N,N-(Diethylamino)ethyl methacrylate의 구조 확인을 위해, Ft-IR, NMR 분석기기를 사용 하여 분석을 진행하였고, N,N-(Diethylamino)ethyl methacrylate를 용제 dimethylacetoamide 와 촉매 Azobisisobutyronitrile를 사용 하여 Mn=10,000로 중합하여 Poly-(diethylamino)ethyl methacrylate를 제조 하였다.Poly-(diethylamino)ethyl methacrylate의 중합도 및 구조 확인을 위해 GPC, NMR, FT-IR 을 이용한 분석을 진행 하였다. Poly-(N,N-(diethylamino)ethyl methacrylate)의 염색력를 확인 하기 위해, 물리적 방법으로, 폴리우레탄우레아 0.5% 에 혼입하여 pH4 의 산성염료에 대한 염색 성능을 폴리우레탄우레아와 우레탄계 염색성향상제 0.5% 와 비교 평가하였다. 무첨가 폴리우레탄우레아는 8등급, 우레탄계 염색 향상제는 4.5등급, poly-(N,N-(diethylamino)ethyl methacrylate) 0.5% 는 3등급의 결과를 보였다.
The polyurethane urea fiber, or spandex, called the Industrial Revolution, is used in many ways around sportswear, innerwear, and stockings. Advantages include high elasticity, abrasion resistance, chemical resistance, low temperature resistance, aging resistance and oil resistance, and it has disadvantages such as low heat resistance, dye-ability and yellowing due to heat and light. Until recently, in order to overcome these shortcomings, we are actively studying the improvement of polymers, the development of polymer spinning, and the development of additives. In this study, the polymerization of acrylic dyeing enhancer, one of the additives to improve the low-dyeing of polyurethane urea, was studied. N,N-(diethylamino)ethylmetacrylate, the raw material of acrylic chromosomal enhancer, was studied according to reaction time, reactants and types of catalysts for efficient and economical manufacturing methods. To check the 2-(Dithylamino)ethylmetacrylate, Ft-IR, NMR were used for analysis. Using the solvent dimethylacetoamide and catalyst Azobisobutyronitrile, the N,N-(dietylamino)ethyl metacrylate was polymerized to Mn=10,000 to manufacture poly-(N,N-(diethylamino)ethyl methyl metacrylate). An analysis using GPC, NMR, and FT-IR was conducted to confirm the polymerization and structure of poly-(N,N-(dietylamino)ethylmetacrylate). In order to check the dyeing ability of poly-(N,N-(dietylamino) ethylmetacrylate), the dyeing performance of acid dyes (pH4) was compared with only-polyurethaneurea and 0.5% of urethane-based additive by mixing it with of polyurethaneurea. it was result that only-polyurethaneurea is class 8.0, urethane-baes dye additive 0.5% is class 4.5 , poly-(N,N-(dietylamino)ethyl metacrylate) 0.5% is class 3.0.
