The development of natural fibers is restricted by natural conditions, by contrast, the chemical fiber industry mainly relies on synthetic resins, therefore, it is expected the chemical fibers will continue to develop in the future. Man-made fibers can only maintain the current output level, of which viscose fibers still dominate. The output of synthetic fibers will continue to grow. Polyester fibers, polyamide fibers, polyacrylonitrile fibers and polyolefin fibers will still be the main synthetic fibers. With the advanced production technology, the improvement of fiber properties, and the expansion of uses, the variety of chemical fibers will continue to increase. Aramid fibers, carbon fibers, etc. are expected to further increase in output due to their high temperature resistance and high modulus. In the fiber manufacturing process, measures such as increasing the number of spinneret holes and spinning positions, increasing speed, increasing winding volume, and short-path spinning will be adopted to increase single-machine production capacity, save energy, and improve efficiency. To diversify products, chemical or physical methods will continue to be used on fiber modification, thus to expand its application.
