Behavior of Polymer Films and its Blends for Leather Finishing by Caroline Borges Agustini*, Cristiana Winter, Marcia Elizabeth RS and Mariliz Gutterres in Trends in Textile Engineering & Fashion Technology
In the final stage of leather processing, many products are applied to form a protective coating. These coatings include resins such as polyacrylates, polyurethanes and casein. The composition of these materials was compared to physical-mechanical properties, as tensile strength resistance, elongation at break, toughness, hardness and thermal characterization by DSC and FTIR analysis. Tensile strength tests showed that the polyurethane resins, in general, have a higher tensile strength when compared to acrylic resins, as well as the values of toughness, indicating that these films support higher impact before the rupture of the material.
