Does carbon fiber production also fall under chemical enterprises? :lol
Carbon fiber can be produced by carbonizing polyacrylonitrile fibers, pitch fibers, viscose fibers, or phenolic fibers, respectively. The most commonly used carbon fibers are polyacrylonitrile carbon fibers and pitch carbon fibers. The manufacturing of carbon fiber involves four processes: fiber spinning, thermal stabilization (pre-oxidation), carbonization, and graphitization. The accompanying chemical changes include dehydrogenation, cyclization, pre-oxidation, oxidation, and deoxygenation. So it should also belong to the chemical industry.
The chemical industry is incredibly diverse! ! !
Of course, fibers belong to polymers
