| Résumé : |
The effects of the composition of vinyl polymer tannages on the physical properties of leather have been systematically studied with a statistical two-power regression orthogonal design1. Fracture energy was measured along with tensile strength, elongation and tensile modulus for a wide variety of syntan treated pigskin leathers. Eight monomers: acrylonitrile (AN) , acrylamide (AM), methyl acrylic acid (MAA), methyl methacrylate (MMA), vinyl acetate (VAc), methyl acrylate (MA), ethyl acrylate (EA), and butyl acrylate (BA) were chosen respectively to copolymerize with acrylic acid (AA) to form the corresponding copolymers. Tests showed the excellent physical properties of leather treated by the hexa-copolymer composed of AA, AN, AM, MMA, VAc and EA. After performing the retanning application test by using these copolymers as tannages, the physical properties of the retanned leather samples, such as tensile strength, elongation at break, toughness (fracture energy), and stiffness (Young's modulus ) were measured. The results showed the comonomer ratio of vinyl polymer tannages can greatly affect the physical properties of leather. If the comonomer ratio of the hexa-copolymer composed of AA, AN, AM, MMA, VAc and EA is optimized, the hexa-copolymer tannages can offer significant improvements in the tensile strength, elongation at break, toughness (fracture energy), and softness of the leather samples. |
