The diagram illustrates how leather goods are produced from animal skins through a series of stages.
Overall, the process is linear and involves several steps, beginning with drying animal skin and ending with the manufacture of finished products such as shoes, bags, and balls. Transportation between stages also plays an important role in the process.
Initially, animal skins are hung out to dry. After this, they are transported by truck to a factory, where the skins are washed using a mixture of water and lime. The cleaned skins are then soaked in lime before being passed through a flattening machine to remove excess moisture and make them smooth.
In the next stage, the flattened skins are soaked again, this time in tannin, which is a solution made from water and vegetable matter. This tanning process helps convert the raw skin into leather. Following this, the leather is polished to improve its quality and appearance.
Finally, the finished leather is transported to another factory, where it is used to produce various leather goods, including footwear, handbags, and sports equipment.
