Cuirs et peauxIndex. décimale : 675 Technologie du cuir et de la fourrure 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.

- Several relevant chemical structural linkages that can apply to collagen/leather.
- Saline-links do also affect many of the many-properties of leather.
- The thermodynamic stabilizine saline-bridging within the various hierarchical dimensional structures of collagen can be describes.En ligne : https://drive.google.com/file/d/15Twvm5UbGA0_EsNB-_3C2888JWDPe8BG/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11883

TannageIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The control of the chemical reactivity (astringency) of collagen towards the chemicals used in the tannery is essential not only for controlling their penetration and ultimate fixation, but conforms an effective methodology approach towards achievement of nearer stoichiometric completion of the reactions involved and thus can diminish the needless waste caused by the usual excessive offer of chemicals that is often needed to try and force reactions towards completion because of lack in undertaking appropriate reactivity enhancement in collagen. In the current ecological witch-hunt, only the most efficient tanners will survive.
