Abstract
The water vapourpermeability and wet rub fastness of leathers finished with acrylic polymer based resin binder was carried out using the popular water vapour permeability cup method and the VESLIC test method respectively. Five formulations (125 g, 150 g, 175 g, 200 g and 250 g) of the binder which was the factor varied in this experiment, was prepared and then was applied on the originally retanned leathers from which five samples was generated. The effect of the finish formulations on water vapour permeability and wet rub fastness of the originally retanned leathers were investigated. Water vapour permeability test was also carried out for the unfinished (originally retanned) leathers as control samples. The results indicated that the water vapour permeability of the finished leather samples was significantly lower when compared to that of the unfinished (control) leather samples. However, for the finished leather samples, water vapour permeability increases as the quantity of the binder varied in this experiment was increased. The result of the VESLIC test indicated the resistance of the finished leather samples improves as the quantity of the binder varied in this experiment was increased. The overall results showed that the formulations containing the 200 g and 250 g of the acrylic polymer binder are good for leather finishing applications where suitable water vapour permeability and excellent rub fastness are both required.
