Process for producing oxidized or carbon fibers |
| abstract |
Disclosed is an improvement in a process for producing oxidized fibers wherein precursor fibers comprised of oxidizable continuous filaments are repeatedly brought into or out of contact with the surface of a heated body, maintained at a temperature of from approximately 200 DEG to 400 DEG C., in an oxidizing gaseous atmosphere thereby to be oxidized. The oxidized fibers can then be heated in a non-oxidizing gaseous atmosphere maintained at a temperature of at least approximately 800 DEG C. to produce carbon fibers, if desired. The improvement resides in that an interlaced filament yarn is used as the precursor fibers, which yarn substantially has no crimps or loops and is comprised of continuous filaments entangled with each other along the longitudinal direction thereof to an extent such that the coherency factor of the yarn is in the range of from approximately 20 to 100. |
