The given diagram demonstrates the process by which jeans are manufactured from cotton material. Overall, this procedure consists of several stages, beginning with the cultivation of cotton and ending with the distribution of finished jeans to retailers.
In the initial stage, raw materials from cotton fields in Asian countries such as India or China are treated with water and chemicals, and it takes around 160 days for the plants to mature before fibres are harvested and separated to ensure its cleanliness. Moving on to the second stage, the cotton fibres are washed, bleached, dyed and spun into yarn at a factory. At this stage, elastane may be added to make the material more flexible before being woven into denim fabric, resulting in a textile factory, which is then directed to the next stage.
At the third stage, the production is cut and sewn in another factory where buttons and zips are attached. Subsequently, the production of denim was completed by the tailors, ensuring its quality, before shipping to distribution centers in regions such as the USA and Europe. Finally, the jeans are sold in both physical and online stores.
