Leather has a fibrous network gives many favourable properties in line with consumer demands. Thanks to lubrication, both the individual fibers of the network become compliance, thereby, maintaining its mechanical behaviour and the structure would be improved regarding the homogeneity, unity, uniformity and appearance. Hence, the key function of lubricant is to enhance the physico-mechanical properties of leathers and to upgrade their qualities by adding aesthetic value. Those are achieved by use of lubricant emulsions of small particle size capable of deeply penetrating into the hierarchy of tridimensional woven structure. Nano-silica particles are of potential advantages for incorporation into fatliquoring formulations because of their lubricating efficiencies and there will take many interests in terms of attainable value added products with them.
