Abstract: Disclosed are wholly aromatic polyamide filament and a method of manufacturing the same, characterized in that, in the process of preparing the wholly aromatic polyamide polymer, the aromatic diamine, aromatic diacid chloride and polymerization solvent put into the reactor 20 are agitated by an agitation device which is installed in the reactor 20 and consists of: (i) a rotor 3 driven by a motor 2 and having a plurality of pins 3a; and (ii) a stator 4 having a plurality of pins 4a, wherein spin speed of the rotor 3 is controlled to 10 to 100 times of both of feeding rates for the aromatic diacid chloride and the aromatic diamine in the polymerization solvent into the reactor and, at the same time, contact frequency between the pins 3a and the pins 4a is regulated within a range of 100 to 1,000 Hz. The present invention is effective to progress uniform and homogeneous polymerization over all of area of a polymerization reactor 20, thereby reducing deviation in degree of polymerization, since polymeric monomers are miscible and react together very well in the reactor 20. Accordingly, the wholly aromatic polyamide filament produced exhibits narrow PDI and lowered paracrystalline parameter gII leading to reduction of defects of a crystal itself, so as to considerably improve strength and modulus thereof.
