摘要： 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 chlrodie 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 gπ leading to reduction of defects of a crystal itself, so as to considerably improve strength and modulus thereof.

摘要： Disclosed are wholly aromatic polyamide filament and a method of manufacturing the same, characterized by comprising multi-stage injection of a coagulant with sulfuric acid concentration lowered sequentially stage by stage, to a spun material fed into a coagulant injection tank. The present invention enables increase of a spinning and take-up velocity without occurrence of thread cutting by uniformly and evenly coagulating surface and inside of the spun material. In addition, the present invention recovers the coagulant or water already used and reuses the recovered coagulant or water in the earlier stages, so that it has advantages of saving production costs and reducing environmental contamination. Accordingly, the wholly aromatic polyamide filament produced according to the present invention has high crystallinity X, large apparent crystal size ACS and reduced defects in the crystal itself, thereby exhibiting more improved physical properties such as strength and modulus.
