With the progress of science and technology, as a product, chemical fiber has many applications in modern industries. The definition of chemical fiber industry:
Chemical fiber is a kind of fiber with textile properties, which is made of natural polymer or synthetic polymer as raw materials, through the preparation of spinning solution, spinning and post-treatment.
Classification of chemical fiber industry:
1. Regenerated fiber
The production of regenerated fiber is inspired by silkworms' spinning. It is a kind of textile fiber which is made of natural macromolecule compounds such as cellulose and protein, chemical processed into macromolecule concentrated solution, and then spun and post treated.
2. Synthetic fiber
Synthetic fiber is made of synthetic high molecular compound. The commonly used synthetic fibers are polyester, nylon, acrylic, chlorine, vinylon, spandex, polyolefin elastic yarn, etc.
