1: What is Leather Shrinkage caused by Alkaline Overexposure?
1.1: Alkaline overexposure causes the leather denaturing where the leather constituents like the tanning agent and the fatliquor break the hydrogen bond and leach out.
1.2: The tanning agent leather out causes the leather to become tacky when wet.
1.3: The fatliquor leaches out causing the leather to shrink and become stiff, and when flex cracks.
2: How to Remove Alkaline Contamination?
2.1: Alkaline contamination must be removed and the leather pH-balanced with a low pH system.
2.2: Low pH balancing increases the effective hydrogen bonding between the ionic positive (+ve) leather fiber and the ionic negative (-ve) leather constituents like the tanning agent and the fatliquor.

3: How to Restore the Shrinkage?
3.1: Shrinkage is restored by hydrating the shrunk leather to relax, becoming limp, and plump enabling it to be gently stretched back to its original dimension.
3.2: Fatliquoring in sync with hydrating helps lubricate the stick-together fiber to expand and stay separated
sliding one over another smoothly without breaking.
3.3: The softness and suppleness of the leather when dry depends on the percentage of the fat and oil remaining in the leather after drying, thus repeat application once the water content evaporates.
