Résumé : |
A change of molecular structure improves the surface active efficiency of new generation gemini surfactants. As a result, it was confirmed that the dosage could be reduced considerably in industrial applications as performance chemicals, leading to economically quantifiable benefits. The performance of newly synthesized gemini surfactant based sulfonated dimeric malenised soya fatty acid bridged with butane diol was evaluated as a leather fatliquor. The chemical parameters of the fatliquors were analysed and tested on leather. The properties imparted by the fatliquor to leather were studied qualitatively and quantitatively. SEM studies of the treated leathers revealed better penetration of the gemini surfactant based fatliquor compared to the control. Results were correlated in terms of emulsification power, zeta potential and particle size of the surfactants, found to be better than the conventional surfactant. The surface energy was calculated for the fatliquors and found to be equal. |
