The provided diagram illustrates the various stages involved in the production of leather products.
The process consists of several steps starting from the treatment of animal skin with tannin and lime to the final stage involving a chemical reaction in a machine.
The initial steps include drying the animal skin, soaking it in a mixture of water and vegetable matter known as tannin, and then polishing it. Subsequently, the processed skin is transported to a factory where it undergoes washing with water and lime, further soaking in lime, and flattening. Once this is done, the material is once again moved to another factory stage wherein a chemical reaction takes place, as indicated by a machine and effervescence.
In conclusion, the entire leather production process involves a series of distinct phases starting from the treatment of the raw material and culminating in the final chemical treatment. The machinery and specific treatments at each stage play critical roles in creating the end product.
