Abstract: PURPOSE:To obtain filaments from a fiber-forming polymer whose stringiness is not sufficient, by sending a cooling gas to the extruding face of a spinneret and its vicinity while making the dividing member of a meshy spinneret having a given void ratio generated Joule heat. CONSTITUTION:The melt of the fiber-forming polymer 24 is extruded from the mesh spinneret 25 having a void ratio shown by the formula alpha-(Va-Vf)X100/ Va of >= about 10% and a large number of neighboring thin spaces (Va is an apparent total volume occupied in the unit area of the meshy part of the spinneret: Vf is a total volume of the dividing member surrounding the thin spaces, occupied in the unit area of the meshy part of the spinneret). Joule heat is generated from the mesh, and the polymer in a molten state is passed through the mesh to form a fibrous small flow. A cooling fluid from the blower 28 for the cooling fluid is blown to the fibrous small flow, so it is solidified, and wound as a filamentous aggregate by the winder 29.
