碩士 === 國立臺灣科技大學 === 高分子工程系 === 93 === In this study, a series of casein derivative surfactants was prepared by the reaction of casein with carboxylic acids containing decanoic acid ,lauric acid, myristic acid, stearic acid and oleic acid. The structure of these casein derivative surfactants was verified by the FTIR ,1H-NMR, Elemental Analysis .The experimental results indicated that these surfactants were possess of excellent surface-active properties containing surface tension ,wetting power , foaming ,streaming current reading , pH buffer capacity , dispersiny power ,chelating ability for calciumion , scouring and bleaching in cotton , nylon dyeing and dyeing properties in nylon fabiers.
