Myristyl 지방족기를 함유하는 제4급 암모늄염에 의한 PET 섬유의 감량가공 효과

Weight Loss Effects of PET Fibers by Quaternary Ammonium Salts Containing Myristyl Aliphatic Group

MDABM and MDAEW, as a accelerating weight loss agents, were prepared by adding water to myristyldimethylbenzylammonium bromide(MDAB) and myristyldimethylethylammonium ethyl sulfate (MDAE) synthesized. As a result of weight loss finishing of the MDABW and MDAEW with NaOH on PET fiber, the ratio of weight loss of MDABW was very larger than that of MDAEW. This result showed that quaternary ammonium bromide had higher weight loss effect than quaternary ammonium sulfate, and the ratio of weight loss was greatly varied with the kind of quaternary ammonium salts used. In these conditions, proper treatment concentration treatment time, and treatment bath ratio were about 8g/l, 60~90min, and 40 : 1~50 : 1, respectively.
