| titleOfInvention | Carbon-fiber precursor fiber, carbon fiber, and processes for producing these |
| abstract | Precursor fibers for high-grade carbon fibers reduced in fluffing are provided without impairing productivity. The carbon-fiber precursor fibers have a weight-average molecular weight, Mw(F), of 200,000 to 700,000 and a polydispersity coefficient, Mz(F)/Mw(F) (Mz(F) indicates the z-average molecular weight of the fibers), of 2 to 5. Also provided is a process for producing the carbon-fiber precursor fibers. Furthermore provided is a process for producing carbon fibers from the carbon-fiber precursor fibers. In this process, fluffing and fiber breakage are inhibited even under burning conditions including a high tension or high stretch ratio to produce high-grade/high-quality carbon fibers without impairing productivity. Still further provided are carbon fibers which have a crystallite size and a parameter concerning the surface of the carbon fibers and determined by Raman spectroscopy, the crystallite size and the parameter satisfying a specific relationship. |
