碩士 === 國立臺灣科技大學 === 高分子工程系 === 91 === A series of surfactants have been synthesized by the reaction of diethylenetriamine、triethylenetetramine、tetraethylenepentamine、epichloryhydrin and dicyandiamide . 　　1H-NMR、FTIR and element analysis have been used to confirm structure of these compounds. These surfactants have been found to exhibit excellent surface active properties including reducing surface tension、pH buffer capacity、wetting power. These surfactants also have been found to improve the dyeability in direct dye-cotton dyeing system.
