PURPOSE:To obtain the titled combined filament yarn having excellent denier evenness and free from defects such as loop, etc., by pulling and aligning two groups of undrawn fiber filaments produced by the melt-spinning through the same spinneret followed by cooling, introducing the aligned filament groups into the heating fluid zone, and taken up at a high speed. CONSTITUTION:Two kinds of filament groups 2 having different single filament deniers and obtained by the simultaneous melt-spinning through the same spinneret 1 are cooled and solidified at <=80 deg.C, aligned by pulling, and introduced into the heating fluid zone 6. The filaments groups are reheated in the zone to >=80 deg.C, and subjected to the hot-drawing under the influence of heat and tension at different drawing ratios of the filament groups, and taken up at a high speed (4,000-6,000m/min). The ratio of the single filament deniers between the filament groups is preferably in the range of 1.5-7.
