The upper part of the spinning orifice (4), punctured at the spinning plate (2), is linked to the funnel-like cross-sectional shaped main converging space (6), which is linked to the first injection hole (30) through the first polymer feeding route (12), and into which the composite nozzle (10) is accommodated. The upper part of the capillary hole (14), punctured at the composite nozzle (10) and whose extruding orifices narrow drastically, is linked to the funnel-like cross-sectional shaped free converging space (16), into which the core-nozzle (20), formed on the second distribution plate (18) and the capillary hole (24) of which is linked to the third injection hole (34) through the third polymer feeding route (26), is accommodated.
