Formulation of Co-cationic Fatliquor for Leather and Determination of Its Properties

The cationic surfactants based on biamide and imidagoline quaternary ammonium salts were synthesized and the content of cations was determined. The fatliquor for leather prepared by the above two cationic surfactants was made. The fatliquoring effect of the single cationic fatliquor and compositions one was inspected by the orthogonal design.
