Apparatus and method for producing melt spinning resin composition and melt spinning apparatus

摘要

Problem to be solved: to provide an apparatus for producing a melt spinning resin composition for providing high handling ability and high continuous supplying property and producing a fiber having a finer diameter, and a method for producing the same.The manufacturing apparatus of the present invention produces a melt spinning resin composition made of a filament.This manufacturing apparatus comprises an extruding portion for extruding 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 to a filamentary form, and a conveying portion for receiving the extruded molded product and carrying it to the next step.The distance between the discharge port of the resin composition and the conveying portion is 50 mm or less, and the diameter of the discharge port is 1 mm or more and 50 mm or less.A method for producing a melt spinning resin composition made of a filament using the manufacturing apparatus is also provided.Diagram
