| Résumé : |
This study concerns the implementation and improvement of a new system that applies ultrasound technology in vegetable tanning, which is an eco-friendly tanning process. The system is versatile and requires no major modifications or expenses for tanneries. In particular, the study investigates the influence of several variables in the fixation stage of a vegetable tannage after penetration under ultrasound. The results show significant differences in the tanning degree of the leathers tested in relation to the pH of the fixation float and the amount of time that the hides remain in it. It has been demonstrated that this tanning system allows to obtain leathers with a high degree of tannin fixation. The leathers we obtained showed no scratches, which are the main cause for their devaluation when applying the traditional tanning system and were suitable for commercialization as high-end leather goods. Ultrasound technology can increase the use of vegetable tannage versus other less eco-friendly types of tannage. |
