PURPOSE: Aramid fiber and a manufacturing method thereof are provided to offer high intensity to the aramid fiber and to increase improve adhesive property with foreign materials by controlling a manufacturing process of the aramid fiber. CONSTITUTION: A manufacturing method of aramid fiber includes the following steps of: manufacturing aromatic poly amide polymers; dissolving the aromatic poly amide polymers to gain spinning dope; spinning the spinning dope with a spinneret(100); forming filament by coagulating the spinning dope in a coagulation bath(200); washing the filament; and drying the washed filament in a drying part(500). |
