초록

n-Tetradecyldimethylbenzylammonium chloride(TDAC)와 n-tetradecyltrimethylammonium methyl sulfate (TTAM)를 합성하고 각각에 물을 가하여 감량촉진제 용액 TDACW와 TTAMW를 각각 제조하였다 제조된 TDACW와 TTAMW 각각을 NaOH와 병용하여 PET섬유를 감량가공처리한 결과, 감량률은 TDACW가 TTAMW보다 훨씬 높게 나타났으며, 적정 처리농도는 약 8g/l, 처리시간은 60∼90분 및 처리액량비는 1:40∼1:50이었다. 밀도와 결정화도는 감량률이 증가할수록 상승하였고, 인장강도는 역으로 감량률이 증가될수록 저하되었다 또한 감량촉진제와 PET섬유와의 반응메카니즘을 고찰하여 감량촉진제가 촉매로서 작용함을 밝혔으며, SEM으로 감량가공된 PET섬유의 표면형태를 관찰하였다.

Weight loss accelerating agents, TDACW and TTAMW were prepared by adding water to n-tetradecyldimethylbenzylammonium chloride( TDAC ) and n-tetradecyltrimethylammonium methyl sulfate( TTAM ) synthesized in our lab. On weight loss finishing of PET fiber with NaOH and TDACW or TTAMW, TDACW showed much more weight loss than TTAMW. Optimum concentration was about 8g/l, treatment time 60∼90min and treatment bath ratio 1:40∼1:50. Density and crystallinity increased with weight loss and tensile strength decreased with weight loss. From the reaction mechanism of weight loss accelerating agent and PET fiber, weight loss accelerating agent was proved to function as a catalyst and the surface structures of PET fibers treated with weight loss accelerating agent were characterized with SEM
