The diagram depicts how leather goods are manufactured from animal skins. Overall, it is clear that this linear process involves the eighth stages, beginning with drying raw materials and ending with selling the products.
In the first step, animal skins, as one of the raw materials, are dried, before they are transported. Then they are shipped by a lorry to factories, where all manufacturing processes start. In the factories, the raw materials are washed into liquid, which has been mixed with lime. After cleaning, they are soaked to remove the water. In the next stage, soaked materials are flattened by a machine. Following this, materials are poured into tannin, including water and vegetable oils, for the dying process. Subsequently, they need to be soaked before they are polished.
In the end, materials are delivered by truck to the factories, where they eventually are produced to make various goods, such as handbags, shoes, high heels, and balls.
