Definition and classification of chemical fiber industry
With the advancement of science and technology, chemical fiber as a product has many applications in various modern industries. The definition of chemical fiber industry:Chemical fiber is a fiber with textile properties, which is prepared by using natural polymer compounds or synthetic polymer compounds as raw materials, through preparation of spinning dope, spinning and post-treatment.Classification of the chemical fiber industry:1.Recycled fiberThe production of regenerated fiber is inspired by silkworm spinning, using natural polymer compounds such as cellulose and protein as raw materials, and chemically processing the polymer into a concentrated polymer solution, which is then made by spinning and post-processing.2.Synthetic fiberSynthetic fibers are made from synthetic polymer compounds. Commonly used synthetic fibers include polyester, nylon, acrylic, chloroacrylon, vinylon, spandex, polyolefin elastic yarn, etc. Source: Time: 2017-02-28 17:55:42
