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.
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
Proprietary leather cleaners – Commercially produced cleaners are commonplace with leather care, but can have negative effects if not closely researched or familiar with the ingredients. Wet cleaning and solvent cleaning – The primary purpose of any wet cleaning on leather is to remove surface soiling. Leather should not be soaked in water.

Tanned leather. Tanning, or hide tanning, is the process of treating skins and hides of animals to produce leather. A tannery is the place where the skins are processed. Historically, vegetable based tanning used tannin, an acidic chemical compound derived from the bark of certain trees, in the production of leather. An alternative method ...
The first structured method for documenting process flow, e.g., in flow shop scheduling, the flow process chart, was introduced by Frank and Lillian Gilbreth to members of ASME in 1921 as the presentation "Process Charts, First Steps in Finding the One Best Way to Do Work". [2]
Oiling is a process whereby leather is hand coated (usually by brush or tampon) with either a raw (un-emulsified) oil or a combination of raw oil, blended with emulsified oils and a penetrating aid. Hand oils can include fragrant oils that help with the smell associated with the leather, e.g., Pine Oil.
