Aniline leather may be referred to as "full aniline" to differentiate between this dye treatment and variants. Semi-aniline leather is produced through a very similar process to full-aniline, but has a thin protective top coat added to protect it from wear and staining.
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.
It is usually considered the highest quality leather. Furniture and footwear are often made from full-grain leather. Full-grain leather is typically finished with a soluble aniline dye. Russia leather is a form of full-grain leather. Corrected grain leather has the surface subjected to finishing treatments to create a more uniform appearance ...
Oiling provides the leather with lubrication to increase their softness [1] allowing it to flex repeatedly without cracking. Leather fibres that are dry and un-lubricated break very easily. Oiling does impart colour and an element of water resistance. Oiling would normally be performed on full grain aniline leathers. The most common type of ...
