The diagram given illustrates the way in which leather is processed for daily use in the production of various goods.
Looking at the illustration, it is immediately evident that leather production is a manmade linear process requiring a combination of both human labor and machinery. Additionally, there are eleven stages involved in this process, beginning with drying animal hides and culminating in the delivery of leather products, such as bags and shoes.
In the first step, animal hides are dried under the sun, after which they are transported by truck to a factory. There, the hides are soaked in a mixture of water and lime to kill harmful bacteria. Following this, they are washed thoroughly and then immersed in lime juice to inhibit further bacterial growth. Once this has been completed, the hides are flattened by a specialized machine to prepare them for the next stages.
At the subsequent stage, the flattened hides are soaked in tannin, a solution made from water and vegetable matter, which enhances their quality. Next, they are polished to improve their appearance. Finally, the processed leather is transported to another factory, where it is used to produce leather goods such as bags and shoes. The process ends when these finished products are retailed or sold for daily use.
