| titleOfInvention | Production of pitch-based carbon fiber |
| abstract | PURPOSE: To contrive to stably produce the subject fiber by mixing a specified amount of iodine with a melt-spun pitch fiber, treating the fiber with air at a specified temperature and subsequently heating and calcining the fiber in an inert atmosphere. n CONSTITUTION: A petroleum-based or coal-based pitch, preferably with 280-340°C m.p. measured by the Mettler method and ≥50% ratio of an optically anisotropic region is subjected to heat treatment, etc., and the treated pitch is melt spun using a slit-shaped spinning nozzle to prepare a pitch fiber. The resultant pitch fiber is subjected to coating, etc., so as to be ≥1.0wt.% (preferably ≥3.0wt.%) iodine content and infusibilized by treatment thereof in air at ≤350°C (preferably ≤300°C). The fiber is then subjected to calcination treatment in an inert atmosphere at ≥1000°C, thus obtaining the objective fiber. n COPYRIGHT: (C)1989,JPO&Japio |
