dc.description.abstractLeather is a product produce by skins and hides that have been treated to preserve them and make them suitable for use. It is the major by product of meat industry. Leather industry is a popular industry not only in Sri Lanka but also all over the world. Buffalo, cow and goat skins are used for leather tanning process in Sri Lanka. Shoes, bags, belts are the some leather products. Tanning is the process that converts the protein of the raw hide or skin into a stable material which suitable for a wide variety of end applications. There are two methods of tannin as vegetable tanning and mineral tanning. Vegetable tanning is done using tannin naturally occurs is plants. Mimosa is one of the commercially available tanning agent uses in leather tanning. In this study, locally available tanning agents were introduced. Tanning medias were prepared using mimosa as treatment 1, king coconut extraction as treatment 2 and tea waste extraction as treatment 3. Cow and buffalo hide tanning was conducted separately for leather production. During tanning period tanning absorption was measured. Properties of final leather, yield, hardness, thickness reduction, water absorption, shrinking temperature and tensile strength were measured. Sensory evaluation for the leather conducted for softness, fullness and overall acceptability. According to the statistical analysis for the cow leather there is no significant difference (P>0.05) between treatments with yield, water absorption, tensile strength and there is a significant difference (P<0.05) between treatments with hardness, thickness reduction and shrinking temperature. Considering properties of buffalo leather there is no significant difference between treatments with tensile strength and there is a significant difference between treatments with hardness, water absorption thickness reduction and shrinking temperature. Though there is a signific4nt difference, treatment 2 shows the better results. Therefore king coconut extraction can be used for the vegetable tanning of leather instead of the mimosa.
