| Résumé : |
In the present investigation, an attempt was made to design an eco-friendly vegetable tanning process without pickling process by the application of enzymes to improve the exhaustion of vegetable tannins. Such an approach has resulted in more than 97% tannin exhaustion in the case of the experimental process, an increase of 12% compared with the conventional vegetable tanning process. The tanned leathers showed an improvement in hydrothermal stability, surface color values and there is no surface deposition of tannins in the experimental leathers, although vegetable tanning was carried out at higher pH. This was substantiated through scanning electron microscopic analysis that resulted in opened up, split compact fiber structure that was well coated by tannins, indicating that the enzyme assisted tanning process did not bring about any major change or destruction on the fiber structure of the leathers. The enzyme assisted tanning process is efficient in terms of improved quality of leather and also led to reduction in total solids (TS), chlorides and COD loads. The enzyme assisted tanning system presented here appears to be a viable option for combating pollution arising from the conventional vegetable tanning system. |
