Abstract:
|
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 inf luence 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 f loat 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. |
