There are multi-cationic groups containing in the structure of surfactants. 1H-NMR、FTIR and element analysis have been used to confirm the structure of these compounds. These surfactants have been found to exhibit excellent surface active properties including low foaming reducing pH buffer capacity、metallic ions dispersancy capacity. These surfactants also have been found to improve the abilities in direct dye-cotton dyeing system. Key word: surfactant、surface activity
