Two different systems of analysis have been tested. In bath methods, salt is removed by stirring the hide with deionized water and analysing the resulting salt bath. The first method is based on the measurement of the chloride amount in the salt bath by the Mohr method. The second method is based on measuring the density of the salt bath. The second method has yielded very good results. Also, it does not require the use of chemical reagents and the necessary equipment is common in all tanneries.

This method allows 74% salt savings compared to the salt consumption in the conventional salting system. World-avide such savings would involve approximately 3 million tons of salt. This salt is now eliminated as contaminated solid waste or dissolved in residual waters. The change in the preservation system cuts the expenses by at least 48 %. Results show that the new method is effective for short-term preservations (1 month) as leathers of equal or superior quality are obtained. This method may also be used in longer term preservations as long as the elongation and the tensile strength requirements are not a priority in the final article.

Cuadros, Auteur ; Mira Cobos, Auteur Année de publication : 2009 Article en page(s) : p. 103-112 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : In response to the current needs of the leather market, competing manufacturers have to be flexible, adaptable and quick at producing leather goods that are both technologically innovative and fashionable. A new coating formulation has been studied in order to obtain an article which meets these two characteristics. The present study aims to obtain a patent leather finish with a pull-up effect. In addition, it aims to make improvements in the process by replacing the usual solvent based patent top with an aqueous patent topcoat. As a result, the article obtained in industrial scale complies with the European Union Council Directive 1999/13/EC of 11 march 1999 (on the limitation of emissions of volatile organic compounds due to the use of organic solvents in certain activities and installations).
The finished leathers obtained with this new coating formulation are transparent, smooth, with a glossy look (almost glass-like) and with an accentuated pull-up effect. All the necessary requirements for shoes uppers and leather goods are met.En ligne : https://drive.google.com/file/d/1A0Fqt3pqPVCS8yJCt7EcXGCe3vkimJrn/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=4481

Tannage Résumé : The process of pickle-tanning results in the significant pollution of wastewaters through the presence of chrome and chlorides. A new process has been studied in order to reduce the negative environmental effect that pickle-tanning causes on leather making. The new process involves a pickle without float and with minimum salt offer as well as the substitution of the inorganic acid by a sulphoaromatic acid. By doing so, the required additions of chrome salt and salt are minimized and this results in high levels of chromium exhaustion in the residual float. When this process is compared to the traditional one, the results obtained indicate that there is a 78 percent reduction in residual float volume, a 93 percent reduction in chlorides content in the effluent and a 95 percent reduction in chrome content in the float.

Tannage Résumé : The traditional chrome-tanning process poses several disadvantages from the environmental point of view including effluent volume as well as chromium and chloride content. We have thus modified the process in order to minimize these disadvantages. The tanning process has been carried out with almost no float by simply utilizing the float already contained in the hide. As there is very little water, the quantity of sodium chloride required to avoid the swelling of the skin decreases sharply, due to the acidic conditions. In a corresponding manner, the mechanical work on the skin increases and the fixation of chrome salt is greater. Water consumption and chrome discharge are dramatically lower using the new system instead of the traditional system. A comparison of results shows that by using the new system water consumption decreases by 78 percent, chrome oxide content by 86 percent and chlorides present in the effluents by 94 percent.
