Résumé : |
Amphoteric surfactant based fatliquors are outstanding performers in the leather industry because of their excellent surfactant properties, low toxicity, good biodegradability, excellent resistance to hard water, antistatic properties, good emulsification, dispersion and compatibility with other agents. This paper reports on the preparation of a new amphoteric surfactant, diethylamino-lauryl itaconate (DEALI) through the synthesis of lauryl itaconate (LI) based anionic polymerisable surfactant (“Surfmer”). DEALI and LI were characterized by FT-IR and 1H NMR spectra. Properties of both DEALI and LI such as surface tension at different concentrations, critical micelle concentration, contact angle, surface energy, emulsification power, zeta potential and particle sizes were measured. The Isoelectric Point (IEP) of DEALI was determined. The amphoteric surfactant (DEALI) and the anionic surfactant (LI) were formulated as fatliquors and applied on wet blue cow leather, against each other. Fatliquor imparted properties on the leather were measured qualitatively and quantitatively. Scanning Electron Microscopic studies of the resultant leather was carried out and found to have better performance due to deeper penetration of the amphoteric surfactant. This work provides a lead for the development of new and better fatliquoring agents. |
