Abstract |
AB |
[EN] The present invention relates to a process for tanning animal hides which comprises the steps of: bating and pickling the animal hide in aqueous solution, reducing the liquid content of the animal hide, replacing at least some of the liquid removed from the animal hide in the preceding step by a tanning solution which contains the tanning agent to be imbibed by the animal hide in an amount not exceeding an excess of 80%, and treating the animal hide containing the tanning solution with compressed gas in a pressurized container for a period of at least 15 minutes. Such a process is substantially wastewaterless, optionally even completely wastewaterless, and delivers high-quality through-tanned leathers or furs after short treatment times. |
