Beschreibung
Zusammenfassung:	Described are a process for the production of acrylic fibers, especially a spinning process to obtain precursor fibers of carbon fibers by wet spinning of polymer solutions in an organic solvent, and a relative apparatus. The process of the present invention, as a spinning process of a homogeneous solution of an acrylic copolymer in an organic solvent, preferably DMAC or DMSO, for the production of precursor fibers, comprises a step of performing wet spinning at a spinning speed ranging from 150 to 400 m/min. 아크릴 섬유의 생산 공정, 특히 유기 용매에서 중합체 용액의 습식 방사에 의해 탄소 섬유의 전구체 섬유를 얻기 위한 방사 공정 및 관련 장치가 설명된다.
