| titleOfInvention | Flame-resistant fiber and carbon fiber, and production method thereof |
| abstract | An object of the present invention is to reduce the decomposition products of flame-resistant fibers in the pre-carbonization step and increase the yield of the obtained carbon fibers. In a flame-resistant fiber obtained by heat-treating an acrylic precursor fiber for carbon fiber, in a DSC measurement from room temperature to 400 ° C. under a temperature increase rate of 10 ° C./min in a nitrogen atmosphere. The flame-resistant fiber is characterized in that no exothermic peak is observed at 350 ° C. ± 10 ° C. This flameproof fiber is obtained by heat-treating an acrylic precursor fiber for carbon fiber at 200 to 300 ° C. for 30 to 60 minutes in an atmosphere having an oxidizing gas concentration of 15 to 25% by volume, and further in an atmosphere having an oxygen concentration of 3 to 12% by volume. It can manufacture by heat-processing at 300-350 degreeC for 1 to 10 minutes. [Selection] Figure 1 |
