Melt spinning resin composition, its manufacturing apparatus, its manufacturing method, method for producing fiber, and melt spinning apparatus

摘要

PROBLEM TO BE SOLVED: To provide a resin composition for melt spinning, which has high handleability and high continuous supply property while preventing thermal deterioration of a raw material without causing a problem in terms of equipment. The resin composition for melt spinning of the present invention is a filament having a melt viscosity of 250 Pa · s or less and a tensile strength of 10 MPa or more at 200 ° C. and a shear rate of 0.1 s- ^1. This filament is produced by molding a melt 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, and cooling the molded product while transporting it.} be able to.
