In this study, we developed a new technology of preparing a leather retanning agent using collagen protein extracted from solid leather waste and recycled into the leather production process. This collagen based retanning agent, bearing a selective filling property, is a potential solution to reduce differentiation between different locations of the leather. The leather, after retanning treatment, is full and has very good mechanical performances, such as tensile strength and tear strength. Thus, the new research has opened up new windows for the treatment of solid leather waste presenting recycling utilisation in the leather industry.

Langues : Anglais (eng) Catégories : Crocodile du Nil Cuirs et peaux -- Analyse Matériaux -- Coloration Peau -- Anatomie et histologie Peaux brutes Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Crocodile leather with its unique pattern and scarcity is regarded as a leader in the high-grade leather products industry. In order to further improve the quality of crocodile leather products, based on the Crocodylus niloticus raw hides, the trichrome-udan IV staining method, aldehyde fuchshin staining method, scanning electron microscope and polarising microscope were used to study the histology characteristics and fibre weaving of the raw hides, which provides a theoretical basis for formulating tanning scientifically and reasonably.
