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.

Abstract: The present invention relates to a textured yarn (ATY) with different shrinkage and excellent suede effect, wherein at least one or two kinds of two-component composite yarn (effect) yarn having a monofilament fineness are twined around a thermoplastic multifilament yarn (core yarn), forming loops on the surface of the textured yarn.

Abstract: The present invention relates to a textured yarn (ATY) with different shrinkage and excellent suede effect, wherein at least one or two kinds of two-component composite yarns (effect yarn) having a monofilament fineness of 0.001 to 0.3 denier after dividing or extracting an extraction component are twined around a thermoplastic multifilament yarn (core yarn), 2 to 350 loops per meter of the two-component composite yarn of at least 1.0§® in length are formed on the surface of the textured yarn, and more than 95% of the two-component composite yarn loops of at least 1.0§® in length has a length of 1.0 to 2.5§®. The present invention prepares the textured yarn with different shrinkage by air-texturing the two-component composite yarn (effect yarn) and the thermoplastic multifilament yarn (core yarn) in an air texturing nozzle under the condition that the overfeed ratio of effect yarn to core yarn is 1.2 to 4.0.
