2. Fatliquoring - use a pH 5.0 fatliquor (anionic -ve).
3. Post-Fatliquoring - use a pH 3.0 acidifier to further charge the protein fiber (cationic +ve).
Thus you fatliquor it as what was originally done to this leather.
The (-ve) fatliquor hydrogen-bond with the (+ve) protein fiber.
You can get the leather as soft as you wish.
Does what I say makes sense.
There are techniques involve too, and I shall continue if this help!
