One fatliquor is made from pure canola oil, the second one from castor oil and the third one is made from a mixture of different oils, which is termed here as ‘Blended oil’. Canola oil is used for fat-liquoring purpose and has been compared with other natural oil based fat-liquors and a commercially available sulfated fat-liquor. Different chemical and physical studies were carried out to find out the fat-liquor producing the best results. Chemical studies of fat-liquor such as pH, fat content, solid content, moisture and organically combined sulfuric anhydride were determined before its application on leather. The physical studies such as tear strength, tensile strength, elongation, burst load, softness and distention were carried out on crust leather. The fat content test was carried out to check the uptake of fat-liquors by leather samples. On the basis of chemical and physical analysis the blended oil based fat liquor was found to be better than the castor & canola oil based fatliquors and commercially available sulfated fat-liquor.

SulfonationIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : 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.

Produits de nourriture du cuirIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Rape oil-based fatliquors were prepared from different methods such as sulfated, sulfonated, oxidized-sulphited, phosphated or copolymerization and their biodegradabilities were investigated by evaluations of the respirations, BOD5/COD values and COD, TOC removal ratios. The results indicate that the BOD5/COD values and the COD, TOC removal ratio of all products are higher than 0.45 and 85 %, respectively, showing a biodegradability order of phosphate>sulfonated>oxidized-sulphited>sulfated>copolymeric and biodegradable characteristics. Further study indicates that the difference in the biodegradability is closely related to the content of double bonds and hydroxyl groups in resultant fatliquors for different modification methods ; the one which consumes the double bonds or hydroxyl groups will decrease its biodegradability, whilst others which do not consume the double bonds or hydroxyl groups will impart the product better biodegradability.
