Disclosed are a method of folding multiple filaments and a bundle of filament produced by the same. More particularly, the method of folding multiple filaments includes release-winding the filaments under a uniform release-winding tension, folding the released filaments in non-twisted states and winding the folded filaments to produce a bundle of filament, so as to effectively prevent some of the filaments in the bundle of filament from hanging down or becoming loose due to different tensions when the bundle of filament is release-wound for post processing. The bundle of filaments includes a plurality of filaments combined together in a non-twisted manner and has highly uniform weight of the filaments per unit length of the bundle of filament, wherein the standard deviation of the weight of each filament ranges from 0.0001 to 0.01 from their average weight.

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 pathsand outer pathswhich 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 reactorthrough corresponding one among the inner and outer pathsand. The present invention is effective to progress uniform and homogeneous polymerization over all of area of a polymerization reactorleading 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. Accordingly, the wholly aromatic polyamide filament produced exhibits narrow PDI and increased ACS, so as to considerably improve strength and modulus thereof.

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.
