FALSE TWIST TEXTURED SYNTHETIC POLYMER FILAMENT YARN Abstract Of The Disclosure The invention is directed to filament yarns made from synthetic polymers and having false twist texture, compris- ing a core filament group and a sheath filament group wrapped around and partially covering the core. The sheath filament group comprises at least two filament groups 4 and 5 with dif- ferent cross-sections, the smaller component of the sheath filament group including fibrils with the coarsest denier, and the larger component of the sheath filament group containing fibrils with the finer fibril denier, the finer fibrils in the filament group having a lesser fibril denier than the fibrils 3 of the core group 1.
