The soaking of leather
Rawhide and skins are delivered to the tannery and soaked in cold water. Soaking prepares the skin for the next steps. The tanner uses rotating barrels for this.
Dry skins are generally first soaked in a pit or in a rotating barrel. Chemicals, which accelerate the softening process, are added to the water - usually at about 10 to 20 ° C. The soaking can vary from a few hours up to several days (air dried leather).
Task of the soaking
- Restoration of the original water content before the preservation.
- The restoration of the swelling as before the preservation.
- Cleaning the skin of dirt, manure and blood.
- Removal of preservatives and disinfectants, if any.
