PURPOSE:A specific surfactant is applied to acrylic gel fibers resultant from wet-spinning, drying is effected to density the fibers and a fluorine surfactant is applied to the fibers to give the titled fiber of reduced fusion, which are suitably used for production of carbon fibers of high strength. CONSTITUTION:At least one selected from surfactants and fluorine-containing surfactants of formula I-III [R1 is 11-17C aliphatic hydrocarbon; R2-R4 are H, lower alkyl, hydroxyethyl, hydroxypropyl; X is formula IV; X' is formula V (R5-R7 are H, hydroxyethyl)] is applied to acrylic gel fibers obtained by wet spinning. Then, the fibers are densified by drying and treated with a fluorine-containing surfactant, in addition. |
