| Résumé : |
This research addresses the significant challenges in converting back cut skins of Nile crocodiles (Crocodylus niloticus) into soft leather. The process is complicated by the skins’ inherent hardness and distinct texture. Sourced from the Arba Minch Crocodile Farm, these skins are aesthetically pleasing due to their unique scale patterns. However, they are often overlooked by leather manufacturers because of their rigidity and the complexities involved in processing. Our study proposes a critical modification in the pickling and chrome tanning process, specifically designed to improve fiber opening and separation. This method effectively transforms the durable back cut skins into flexible, soft leather, enhancing their applicability in various leather goods. Furthermore, the research encompasses an extensive evaluation of the raw materials, focusing on their fat and nitrogen composition. Advanced techniques, such as scanning electron microscopy analysis, along with visual examinations and physical tests, affirm the modified tanning process’s efficacy in producing soft leather from crocodile back cut skins. These findings underscore the potential of this refined approach not only to overcome processing challenges but also to expand the use of back cut skins in the leather industry. This research not only offers new opportunities for product diversification but also promotes sustainable practices at Ethiopian Nile Crocodile Farms, contributing to innovative and environmentally responsible leather production methods. |
