Abstract: Disclosed is a bulletproof material having superior bulletproof performance and enhanced back-side deformation characteristics along with superior wearing sensation due to relatively light weight and soft texture. The bulletproof material according to the present invention includes a fibrous layer including a carbon fiber network at a back side or near a back side.

Abstract: 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 filament includes a plurality of filaments folded together in non-twisted states and has a standard deviation in weight of the filaments per unit length of the bundle of filament ranging from 0.0001 to 0.01.
