| titleOfInvention | An improved chrome tanning procedure |
| abstract | An improved chrome tanning procedure. # The use of water during leather manufacturing is inevitable, as it is important for the diffusion and distribution of chemicals in the leather matrix. Because a larger volume of water is used during several unit procedures, effluent discharge increases correspondingly with contaminants. The present invention relates to the prevention of the use of water for a chrome tanning procedure free of pickling-basification. Auxiliary chemicals, such as fatty liquors, are used to improve chromium depletion during the tanning process. In addition, the use of salt and the basification procedure are avoided in the new procedure. The organoleptic and resistance properties of tanned leathers are on par with those of conventionally processed leathers. This new invention makes an effort to use the water inherent in the leather for tanning in order to achieve sustainability with reduced pollution loads. |
