The soaking of leather
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.
