  • Patent number: 10731230
    Abstract: The invention concerns a process for tanning hide to obtain leather. The general process for obtaining the intermediary wet blue stage comprises the following steps: a) a picking step with acid and salt, followed by b) a tanning step with chromium salt, followed by c) a basification step. The invention is characterized in that the bath of the pickling step comprises organic acids selected from 2-Methyl glutaric acid (MGA), ethyl succinic acid (ESA) and mixture thereof instead of the traditional strong acid, generally sulfuric acid This process requires less basification agent and enables an increase of the up-taking of the re-tanning products. This invention provides leather with improved mechanical properties.
