The flowchart illustrates the stages involved in the production of leather, showing how raw animal skin is transformed into finished leather goods such as bags and shoes.
The process begins with the drying of animal skin, which is then transported to a factory. At the factory, the skin undergoes a washing process that involves water and lime to remove impurities. Following this, it is soaked in a mixture of tannin, water, and vegetable matter, a crucial step in preparing the material for further processing.
Next, the skin is flattened to ensure uniform thickness before being soaked in lime once again. This additional soaking further refines the texture of the leather. Afterward, the leather is polished to enhance its appearance and quality.
In the final stage, the polished leather is transported to another factory, where it is used to manufacture leather products such as shoes and bags.
