| Résumé : |
Fatliquoring is an important process in leather manufacture and these fatliquors are mainly chemical modification products of animal and vegetable oils. Palm oil, owing to its main characteristics and fatty acid composition is suitable as a raw material for fatliquor preparation. And organosilicone is increasingly used for leather production due to its excellent properties. In this paper, the organosilicone modified palm oil fatliquor was synthesized by amidation with diethanolamine, grafting with hydroxyl-terminated organosilicone, esterification with maleic anhydride and sulfiting with sodium bisulfite, in turn. The influence of the mass percentage of diethanolamine, hydroxyl silicone, maleic anhydride and sodium bisulfte on the emulsion stability and fatliquoring properties were explored; the reaction temperature and time were also studied. The FT-IR spectra analyses showed that the organosilicone chain segment was incorporated into the fatliquor molecule. The route of synthesis and the best conditions of preparing organosilicone modified palm oil fatliquor were determined. The result of applied experiments showed that this new type of fatliquor had excellent emulsion and dispersion characteristics, and the resultant leather was flexible and full. |
