| titleOfInvention | Sea-islands type pitch based carbon fiber and method of producing the same |
| abstract | The present invention relates to a method for producing a fine pitch fiber by producing a fine pitch fiber by spinning a petroleum or coal-based aromatic hydrocarbon material at a high softening point pitch using a alkali-based copolymerizable polymer and a sea- And a photosensitive crosslinking agent is added. When the fine pitch fiber containing the photosensitive cross-linking agent is irradiated with ultraviolet rays, the skin layer and the core layer of the fiber chemically structurally undergo a photosensitive cross-linking reaction. When the carbon fiber is produced through the incompatibility process and the carbonization process, And the structural defects are reduced due to the occurrence of cyclization or aromatization of the additive in the fiber due to the structure of the additive, thereby making it possible to produce pitch-based fine carbon fibers improved in the defect of thick cross section appearing in coarse carbon fibers. |
