Abstract

　本発明により、２００００～３００００の紡糸孔を有する紡糸口金を用いて紡糸して得た凝固糸ストランドを、空気の吹出し圧が２０～６０ｋＰａのインターレースノズル中を通過させて前駆体繊維を得た後、これを加熱空気中２００～２８０°Cで酸化処理して酸化繊維を得、この酸化繊維を不活性ガス雰囲気中、温度３００～９００°Cで、１．０３～１．０６の延伸倍率で一次延伸し、その後０．９～１．０１の延伸倍率で二次延伸する第一炭素化処理を行い、次いで不活性ガス雰囲気中、１３６０～２１００°Cで第二炭素化処理を行ない、その後無機酸塩水溶液中で炭素繊維１ｇ当りの電気量２０～１００クーロンで表面酸化処理して製造される、ストランド引張り強度が５６５０ＭＰａ以上、ストランド引張り弾性率が３００ＧＰａ以上、ストランド幅が５．５ｍｍ以上、ストランド割れ評価方法においてストランド割れが観察されない炭素繊維ストランドが開示される。
