Caractérisation
Croûte (cuir)On entend par "cuir en croûte" des cuirs ayant subi les opérations jusqu'au tannage, à l'exclusion de toute opération de corroyage ou de finissage, mais qui, par opposition aux wet-blue ont été séchés.

| Résumé : |
Ethiopia has the largest livestock population in the African countries, providing a strong raw material base for the growing leather and leather products sector. The main source of raw material for the Ethiopian tanning industry comes from sheep, goat and cattle. Since the Ethiopian leather industry is booming, the industry is now looking to exploit the alternative raw materials available in the country. Camel (Camelus dromedarius) is one of the most important livestock in the East African countries. Due to lack of awareness and technology, most of the hides are not utilized fully by the tanners. Hence an attempt has been made in the present study to exploit the camel hides as an alternative source of raw material for the growing Ethiopian leather industry. Histological analysis of the camel hide has been carried out at different stages of processing. Based on the histological understanding, the strategy for making suitable leather from camel hide was established. The raw material has also been characterized for fat, nitrogen and collagen content. The raw material has been converted into finished leather by using suitable tanning methodology and the leathers were utilized for the preparation of different types of end products. Finished leathers have been developed and the physical and chemical properties have also been evaluated. The results obtained from the chemical and physical tests revealed that the raw material is suitable for the manufacture of upper leather. |
