Since the 20th century, chemical fibers have been produced with the development of polymer materials. The advent of chemical fiber has changed the history that mankind has only used natural fiber as the only textile fiber raw material for thousands of years, and opened up a broad prospect for obtaining new and better textile fibers. The raw materials of chemical fiber come from oil, natural gas, coal and agricultural and forestry by-products. With the rapid growth of petroleum industry, the variety, quantity and technical level of synthetic fiber far exceed the production of man-made fiber. In the production process of chemical fiber industry, the safety and stability of pipeline system is the key to production. Valve products need to be able to deal with the complex situation in chemical fiber pipeline system, so as to make the pipeline system run more freely in the production process.
