Beschreibung
Zusammenfassung:	The resin composition for melt spinning of the present invention is a filament having a melt viscosity of 250 Pa·s or less at 200°C and a shear rate of 0.1 s-1 and a tensile strength of 10 MPa or more. The filament can be produced by forming a molten liquid of a resin composition having a melt viscosity of 250 Pa·s or less at 200°C and a shear rate of 0.1 s-1 into a filament shape to provide a formed material, and conveying and concurrently cooling the formed material. The present invention also provides a resin composition for melt spinning being a filament, and a method for producing fiber using a melt spinning apparatus.
