ABSTRACT:
An improved spinneret for use in producing composite filaments, comprises: nozzles for feeding at least an island constituent melt; a combining chamber having a horizontal bottom surface, into which chamber a sea constituent melt is introduced, the combining chamber having discharging outlets for the sea melt in combination with the respective nozzles, each combination being connected to an outlet for extruding a primary composite melt stream of a "core in sheath" type or a secondary composite melt stream of an "islands in a sea" type. The improvement being in that the combining chamber has feeding holes at the bottom surface thereof for the sea melt, in such an arrangement that the feeding holes are located substantially uniformly over the entire bottom surface of the combining chamber, and the extruding outlets are grouped into respective groups, each group having the same number of extruding outlets and the extruding outlets in each group are located equiangularly along a circle, whereby each circle has the same diameter, the respective circles having centers at which the feeding holes are located and being substantially equally spaced apart from the neighboring circles.
