The diagram illustrates the step-by-step process of producing leather goods from animal skin. Overall, it involves several key stages, beginning with drying the animal hides and ending with the creation of items, such as shoes, bags, and other leather products.
Initially, the animal skins are dried before being transported to a factory for further processing. At the factory, the hides are rinsed in a mixture of water and lime to remove impurities. After this cleaning, the skins go through a soaking phase in lime solution, preparing them for flattening using specialized equipment.
Next, the flattened leather is treated by another soaking phase using tannin solution, which is made from water and vegetable matter. This process further refines the leather. Once soaked, the leather is polished to achieve a smooth finish, making it ready for manufacturing commercial products. In the final stage, the polished leather is delivered to a manufacturer, where it is turned into various products such as shoes, bags, and sports gear.
