The diagram illustrates the process of producing leather goods from animal skin.
Overall, the production of leather goods involves several stages, beginning with drying animal skin and transporting it to a factory. The skin is then washed, soaked, flattened and polished before being sent to another factory, where it is made into various leather products.
Initially, animal skin is dried before being loaded onto a truck and transported to a factory. Upon arrival, it is washed in a mixture of water and lime to remove unwanted substances. Following this, the skin is soaked in lime for a period of time.
In the next stage, the material is passed through a machine to flatten it. After that, it is transferred to another container, where it is soaked in tannin, which consists of water and vegetable matter. Once this process is completed, the leather is polished using specialised equipment to improve its surface.
Finally, the polished leather is transported by truck to a second factory. There, it is manufactured into a range of finished products, including shoes, handbags and other leather accessories.
