ConfitageLe confitage est une action biochimique effectuée au moyen de produits enzymatiques, qui a pour but de dégrader les fibres élastiques, contribuant ainsi à augmenter la souplesse du cuir. En outre, les enzymes complètent la dégradation des résidus épidermiques, donnant ainsi une fleur plus propre et plus lisse.

| Résumé : |
The U.S. hides and leather industries are facing many challenges today, such as overcoming relatively high U.S. energy and labor costs; meeting environmental imperatives ; quantifying, maintaining, and improving current hides and leather product quality; developing new processes and products ; and improving utilization of waste. One of our efforts to address these new challenges is to develop new uses and novel biobased products from hides to improve prospective markets and to secure a viable future for the hides and leather industries. We hypothesize collagen fiber networks derived from un-tanned hides can be utilized to prepare high performance green composites and air filters, of which both have a great market potential. This study focused on understanding the effects of processing steps such as bating, pickling and crosslinking treatments on the morphology and physical properties of the fiber networks derived from un-tanned hides, which will be the starting material for constructing air filters and green composites. Results showed that glutaraldehyde treatment yielded a highly open structure, in which the fibers are well separated from each other. This could be attributed to the action of acids during the pickling step. |
