Influence of Gemini Cationic Surfactants for the Dyeing Property of Modified Polyester Fibers

Using Gemini cationic M and other auxiliaries mixed together,such as 1815 and Poly-cationic S,the influence of the Cationic dye on the dyeing property of Modified Polyester CDP and ECDP was studied,and the interaction between Gemini cationic M and dyes were investigated.The results indicated that Gemini cationic M could be used as the retarding agents of ECDP;however,there was little effect on CDP,the difference of retarding effect was related to the high surface activity on Gemini cationic M.
