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 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.

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.

摘要： Disclosed are wholly aromatic polyamide filament and a method of manufacturing the same, characterized in that, in a process of preparing wholly aromatic polyamide polymer, a multiple tubular feed pipe for polymeric monomer and polymerization solvent with specific construction of adjacent inner paths 11a and outer paths 11b which are alternately arranged one another is used to feed either aromatic diacid chloride A or aromatic diamine dissolved in the polymerization solvent B into a polymerization reactor 20 through corresponding one among the inner and outer paths 11a and 11b. The present invention is effective to progress uniform and homogeneous polymerization over all of area of a polymerization reactor 20 leading to reduction of deviation in degree of polymerization, since polymeric monomers are miscible and react together very well immediately after putting the monomers into the reactor 20. Accordingly, the wholly aromatic polyamide filament produced exhibits narrow PDI and increased ACS, so as to considerably improve strength and modulus thereof.
