The production of blue jeans, made from a very solid and cotton fabric called Denim, begins with the roll of this "denim" fabric. This large and gigantic roll is cut and the layers are separated. The separated layers are divided into pieces and shaped according to the models. Other parts such as pockets are mounted with staples. The final stage is the planting phase. Blue-jean is sewn in 100% cotton yarn. A sewing needle enters the fabric approximately 4000 times per minute. Different designs are machined in pockets or other parts by machine.
