Résumé : |
The high temperature emulsifying lipid complex, hydrogenated and sulfonated fatty acid methyl ester — alkyl alcohol amine (HSF-AM), was prepared. As a fatliquoring agent, HSF-AM can be emulsified and dispersed by adding HSF-AM into water above 40°C. The emulsion was stable when HSF-AM was mixed respectively with 1% 1-12SO4 and 5% plant-based tannins. The chemical oxygen demand (COD) and turbidity in the fatliquoring spent liquors alter the fatliquoring process of goatskin shoe upper leather was reduced when HSF-AM spontaneously precipitated at room temperature for the four mixtures of sulfonated rapeseed ail (SFIO) and HSF-AM. The leather samples presented excellent light fastness and low fogging values due to the high saturation degree (low iodine value), the good nanometer dispersion (120nm), and the stability of the nanoparticles emulsion. |
