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: Disclosed is a method for manufacturing bulletproof fabric, the method comprising weaving fabric; scouring the fabric; applying a pretreatment process to the scoured fabric; and applying a water-repellent process to the pretreated fabric, wherein the pretreatment process comprises adjusting a moisture regain of the scoured fabric. In this method, the fabric is treated with the pretreatment process before the water-repellent process, so that it is possible to maintain the constant concentration of water-repellent composition, and to permeate the water-repellent agent into the fabric with easiness, thereby producing the bulletproof fabric with the uniform and good water-repellent property. Thus, even though the bulletproof fabric is used for a long period of time, it is possible to prevent deterioration of the bulletproof property in the fabric.
