Zusammenfassung:	The present specification relates to a manufacturing method of copolymerized aramid fiber and copolymerized aramid fiber. The manufacturing method of copolymerized aramid fiber comprises the steps of: preparing an aramid polymer by polymerizing a diamine compound and an aromatic diecid halide compound; preparing a copolymerized aramid dope by mixing the aramid polymer with an organic solvent; and spinning the copolymerized aramid dope. The step of preparing an aramid polymer includes a step of raising a temperature at a temperature increase rate of 0.1 to 10℃/min. 본 명세서는 디아민 화합물 및 방향족 디에시드 할라이드 화합물을 중합하여 아라미드 중합체를 제조하는 단계; 상기 아라미드 중합체를 유기 용매와 혼합하여 공중합 아라미드 도프(Dope)를 제조하는 단계; 및 상기 공중합 아라미드 도프(Dope)를 방사하는 단계를 포함하고, 상기 아라미드 중합체를 제조하는 단계는 0.1℃/min 내지 10℃/min의 승온 속도로 승온시키는 단계를 포함하는 것인 공중합 아라미드 섬유의 제조방법 및 공중합 아라미드 섬유에 관한 것이다.
