The diagram illustrates a process involved in the production of leather, a material commonly used in everyday life. The process can be divided into three main stages. Initially, the leather is left to dry and undergoes initial transportation. Following this, it undergoes washing and soaking, and finally, it enters the last stage of processing in the factory.
To begin with, the leather must be thoroughly dried and then transported to the factory for washing and soaking using a special formula prepared for this purpose. Once these processes are completed, the leather is ready for flattening.
The flattened leather is then left for soaking in a solution containing special chemicals, including water and tannin vegetable matter. After this soaking process is completed, the polishing stage begins. The polished leather is then transported by trucks to the final factory stage, where it is transformed into usable leather items such as shoes, bags, and balls.
