The fabric is made of yarn, which, in turn, is made of fiber. The quality of the fabric obtained at the output strongly depends on the characteristics of the fibers.
fibers are divided into natural and chemical, originating from natural raw materials or obtained as a result of chemical synthesis, for example, polymer fibers. The whole technology is conditionally divided into three stages:Spinning; Weaving;Finishing.
