Background
Chemical fibers are fibers made of natural or synthetic high molecular substances by chemical or physical processing. Because of the different sources of the used high molecular compounds, the high molecular compounds can be classified into artificial fibers using natural high molecular substances as raw materials and synthetic fibers using synthetic high molecular substances as raw materials, which are referred to as chemical fibers for short.
Due to the reduction of cultivated land and the attention of environmental protection, the yield of natural fibers (cotton, hemp, wool and silk) is increasingly restricted, and with the development of society, the living standard of people is improved, and the application of chemical fibers is greatly improved.
