The diagram illustrates the process of producing leather goods from animal skin. Overall, it can be seen that the process consists of several stages, beginning with the collection of raw animal skin and ending with the manufacturing of final products in a factory.
At the first stage, the animal skin is obtained and transported by truck to a factory. After that, it is dried under the sun. Once the skin becomes dry, it is soaked in a mixture of water and lime to remove any dirt and prepare it for further treatment. Following this, the skin is washed again with clean water.
In the next step, the skin is soaked in a solution containing water and tannin, which is a natural substance used for tanning. This stage helps soften and preserve the material. After tanning, the skin is flattened using a special machine to make its texture smooth and even.
Once the skin is flattened, it undergoes the polishing stage to improve its quality and appearance. After polishing, the finished leather is transported once more to a factory. In the final stage, the processed leather is used to produce various items such as shoes, bags, and sports equipment.
