The diagram illustrates a process in which leather is produced. Overall, the process comprises 12 stages, starting with animal skin is deliveried, finishing with the waxing.
At the beginning of the process, hides are transported from farm to the factory, after which, those skins are sorted into two groups based on their bulk (large and small). At the third stage, large pieces undergo trimming to eliminate excess material. After that, once the animal skin is added salt, it is stacked and left for 30-days curing. Following this, the hide is then soaked in the water for 12 to 24 hours to be cleansed.
The process continues with the animal skin being dehaired using a knife before the pickling process combining salt and acid ensure the material is treated and softened. Next, it undergoes tanning with chemicals in 48 hours, which is followed by the material being then softened and dyed in a colouring stage, where oils and pigments are added. After all, the skin dried in the next stage before finishing with waxing to refine the surface of the leather.
