Abstract: 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.

Abstract: The present invention relates to a method for treating high-strength fabric to be water-repellent, which includes dipping a high-strength fabric in a water-repellent agent composition to impregnate the high-strength fabric with the water-repellent agent composition, and then, using an air-suction machine to pick-up a part of the water-repellent agent composition impregnated in the high-strength fabric before drying and heating the same. The present invention has advantages in that a part of the water-repellent agent composition impregnated in the high-strength fabric may be uniformly picked-up during dipping, so as to improve water-repellent performance, especially, water-repellency after friction as well as initial water-repellency, and may effectively prevent occurrence of wrinkles on the high-strength fabric during water-repellent treatment. The high-strength fabric obtained by water-repellent treatment according to the present invention exhibits increased flexibility without wrinkles, so as to improve wearing comfort. Further, in case of using the fabric as a raw fabric for bulletproof garments, water-repellency is increased to prevent deterioration in bulletproof properties caused by water absorption.

Abstract: 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.
