When exposed to heat in either condition, the leather may lose the ability to absorb water from the air and the result is a hard or brittle state, this is referred to as hysteresis. This is due to the interconnected nature of external heat and moisture content in leather. Water: see the above relationship of heat and moisture content in leather
What is hot water immersion, and what are its benefits? Hot water immersion, also known as hot water therapy, involves fully or partially immersing yourself in hot water (by sitting in a hot tub ...
Leather can be oiled to improve its water resistance. This currying process after tanning supplements the natural oils remaining in the leather itself, which can be washed out through repeated exposure to water.

wetting back- semi-processed leather is rehydrated. sammying - 45-55%(m/m) water is squeezed out the leather. splitting - the leather is split into one or more horizontal layers. shaving - the leather is thinned using a machine which cuts leather fibres off. neutralisation - the pH of the leather is adjusted to a value between 4.5 and 6.5.
