Carbon fibers and activated carbon fibers are manufacturing using spinning, low-temperature and high-temperature treatment technology. Pitch-based activated carbon fibers are manufactured into non-woven roll products through oxidative stabilization and steam activation after producing non-woven fabrics with pitches using the melt-blown spinning method. Carbon fibers and activated carbon fibers are adsorption materials to remove organic solvents and used for deodorizers, dust masks and CBR protection materials.
