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.
