Highlights
The leather finishing comprises a set of treatment steps made at final stage in the process of leather manufacturing in tanneries and fills the important role of ensuring the final appearance and appropriate resistance properties in finished leather and leather goods
The resins are divided according to its application over the leather surface: the resins used for the base layers that can be combined with pigments and should be softer and more flexible and the resins used for the top layers that are responsible for physical properties [7,8,9].The base layer is a soft layer applied in contact with the leather surface
The films were grouped according to the nature of the resin and its use.The toughness values were calculated from the area under the stress-strain curve
Summary
The leather finishing comprises a set of treatment steps made at final stage in the process of leather manufacturing in tanneries and fills the important role of ensuring the final appearance and appropriate resistance properties in finished leather and leather goods. FTIR analysis were used to study molecular structures of polymer blends composed of casein, polyurethane and acrylic dispersions application in base layer for leather finishing [6,19,26,27,38,39,40,41]. The films were grouped according to the nature of the resin (acrylic or polyurethane) and its use (top or base layer).The toughness values were calculated from the area under the stress-strain curve.
