Résumé : |
Collagen is a wonderfully complex starting material making leather, which wa are now only beginning to understand ! Practical tannery recipes arose out of the craftsmanship developed by multiple successive generations of artisan tanners that obtained, by trial and error, the rules of thumb that eventually converted into a technical folklore. Leather chemists then tried to interpret this technology according to the scientific theories of the day, whereas tanners retained the technology that seemed to work best. Although colloidal chemistry has developed tremendously in the last century, some of its principles are not any longer agreable to the leather sector in general, and are regarded with great mistrust. Some of these colloidal concepts can be very useful if properly applied and can be used to produce better leather in better ways ; such then should be the ultimate goal of any working chemical model employed by tanners to be guided in the actual processing of leather. |
