The diagram describes the process of leather products in the manufacturing industry.
Overall, it can be seen that this is a linear human-produced process, which consists of 11 main stages. The process begins with the drying of animal skin and ends with a production of leather goods.
Firstly, the process starts with drying an animal skin, after which it is transported to a factory where it is processed into leather. The skin is then washed in a mixture of water and lime and afterwards it is soaked in lime only. Next, the soaked material is flattened using a machine.
After it is flattened, the material is soaked in tannin, which consists of water and vegetable matter before being polished to improve its appearance. Then, it is delivered in a van to a factory, where it is manufactured into various leather products, including shoes, bags and balls.
