ABSTRACT:
In a flame resistant fiber assembly obtainable by fiber forming a flame resistant polymer, a flame resistant fiber of a higher performance is obtained by improving fiber forming ability. A carbon fiber of a high performance is obtained by carbonizing the flame resistant fiber. At obtaining a flame resistant fiber by subjecting a solution containing a flame resistant polymer modified by an amine-based compound to a wet spinning or a semi-dry spinning in a coagulation bath in such a way that a degree of swelling of a coagulated yarn at the outlet of the coagulation bath is 100 to 1000 wt % and then, in a bath, subjecting to a drawing and/or water washing and to a drying under tension, the flame resistant fiber is produced by controlling temperature of the drawing bath/water washing bath, drying temperature or tension in such a way that the obtained fiber would not crystallize. A carbon fiber is produced by carbonizing the flame resistant fiber.
