Chemical fiber history and classification

Among the raw materials used to produce textiles, cotton, linen, silk, and wool (wool) have the longest history. However, after all natural resources are limited, the output of cotton is about 50 kilograms per hectare, and sericulture is also necessary for raising silkworms. To increase production, animal husbandry should be developed.

As a result, chemists began to study the use of cheaper, more abundant sources of raw materials for spinning fabrics, which are chemical fibers.

The chemical fiber is a fiber having a textile property obtained by preparing a spinning solution, a spinning process, and a post-treatment process using a natural polymer compound or an artificially synthesized polymer compound as a raw material.

Chemical fibers are divided into two categories: 1 artificial fibers, chemical fibers made from natural polymer compounds such as cellulose, such as viscose fibers and acetate fibers. 2 Synthetic fibers, chemical fibers made from synthetic polymer compounds, such as polyester fibers, polyamide fibers, and polyacrylonitrile fibers. Chemical fiber has the advantages of high strength, abrasion resistance, low density, good elasticity, no mildew, no fear of insects, easy washing and quick drying, but its disadvantages are poor dyeability, large static electricity, poor light and weather resistance, and poor water absorption.
