PURPOSE: A para-aromatic polyamide fiber and a manufacturing method thereof are provided to reduce crystallinity of a para-aromatic polyamide fiber and a crystal size to increase a moisture rate, thereby increasing a dyeing property. CONSTITUTION: Spinning dope is spun by a spinneret(10). The spun spinning dope is coagulated in a coagulation bath(20) through an air gap. A filament containing sulfuric acid is cleaned in the first water cleaning bath(30). The filament is cleaned in the second wafer cleaning bath(40). The first and second cleaning rollers(31,41) move the filament. A drying roller(51) eliminates moisture from the filament. A winder(60) ties the filament. |
