| Résumé : |
Vegetable tanned leather is very sensitive to environmental factors, especially acidic pollutants. In addition to environmental factors, the type of animal and tannin consumed highly influences the structure and deterioration of leather. Therefore, this comparative study aimed at evaluating the stability of sheep and goat leather, tanned with mimosa extract, during the accelerated aging process. The leathers were submitted to accelerated aging for two weeks at 40°C, 50% RH and 100 ppm SO2 concentration. The attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy, colorimetry, fiber-optics reflectance spectroscopy (FORS), pH measurements, investigation of mechanical properties and shrinkage temperature (Ts) were used to investigate influence of the accelerated aging condition on physical and chemical properties of leather. Results showed that sheep leather has better structural stability against acidic deterioration with compared to goat leather. While, goat leather showed higher color stability than sheep leather. Moreover, results revealed that deterioration level in grain layer was more severe than corium. |
