PURPOSE:To carry out the simultaneous spinning combination of filaments, by arranging two or more spinnerets along the blasting direction of the quenching air stream in a manner to give difference between the distances below the spinneret, thereby causing sufficiently large difference in the physical properties. CONSTITUTION:A plurality of spinning packs are arranged in a manner to vertically stagger the spinnerets 3 and 4. The spinning pack having smaller distance Xi from the spinneret (Xi is the length between the lower end of the spinnerets 3, 4 and the top of the blasting port 5 of quenching air stream) is positioned to the side of the blasting port 5. The filaments extruded from the pack having smaller distance from the spinneret are preferentially cooled to cause the difference in the physical properties. The cooled filament yarns Y1 and Y2 are combined with a fluid nozzle, etc. and wound.
