Fatliquor is an oil-in-water emulsion that improves the physical properties of leather such as tensile strength, flexibility, and softness by lubricating the leather fibres. Sulfonated Sesamum indicum oil was synthesized, characterized, and examined for consideration as a substitute for imported fatliquor in Nigeria. The sulfonation of the oil was confirmed by the significant observations made in the FTIR, 1H NMR, 13C NMR, and 13C NMR DEPT analysis results. A remarkable difference was observed in the physicochemical properties results of both unsulfonated and sulfonated oils. The sulfonated sesame fatliquor was applied onto goatskin and compared with a commercial sulfated fatliquor in the processing of shoe upper leather using standard methods. The average results for tensile strength, double edge tear, elongation, and softness results for the commercial and synthesized fatliquors are as follows: 14.27 N/mm2; 13.77 N/mm2, 50.61 N; 60.11 N, 38.06%; 54.28%, 25.2; 25.0. A comparable level of lubrication of the leather treated with the sulfonated Sesamum indicum oil and that treated with the commercial leather fatliquor was revealed by the Sudan IV stain test as well as scanning electron microscopy analysis results. Experimental analyses, therefore, show that the as-synthesized sulfonated Sesamum indicum oil could be considered as a substitute for imported fatliquor in the leather industry.

磺化芝麻种子油的合成及其在皮革加脂中的应用

加脂剂是一种水包油型乳液，可通过润滑皮革纤维来改善皮革的物理性能，例如拉伸强度，柔韧性和柔软性。合成了磺化的印度芝麻油，进行了表征，并进行了研究，以考虑替代尼日利亚的进口加脂剂。通过FTIR，1 H NMR，13 C NMR和13 C NMR DEPT分析结果中的重要观察结果证实了油的磺化。未磺化油和磺化油的理化性质结果均观察到显着差异。将磺化芝麻加脂剂涂在山羊皮上，并与采用标准方法处理的鞋面皮革中的市售硫酸化加脂剂进行比较。拉伸强度，双边缘撕裂，伸长率，商业和合成加脂剂的柔软度结果如下：14.27N / mm 2；13.77 N / mm2，50.61 N; 60.11 N，38.06％; 54.28％，25.2; 25.0。Sudan IV色斑测试和扫描电子显微镜分析结果表明，用磺化芝麻籽油处理过的皮革和用商品皮革加脂剂处理过的皮革的润滑水平相当。因此，实验分析表明，合成后的磺化芝麻籽油可以被认为是皮革工业中进口加脂剂的替代品。Sudan IV色斑测试和扫描电子显微镜分析结果表明，用磺化芝麻籽油处理过的皮革和用商品皮革加脂剂处理过的皮革的润滑水平相当。因此，实验分析表明，合成后的磺化芝麻籽油可以被认为是皮革工业中进口加脂剂的替代品。Sudan IV色斑测试和扫描电子显微镜分析结果表明，用磺化芝麻籽油处理过的皮革和用商品皮革加脂剂处理过的皮革的润滑水平相当。因此，实验分析表明，合成后的磺化芝麻籽油可以被认为是皮革工业中进口加脂剂的替代品。
