Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for stably producing polyvinyl chloride-based fiber hardly causing troubles due to fiber cut. SOLUTION: The method for producing polyvinyl chloride-based fiber comprises using a single shaft extruder with a screw of 1.1-2.0 compression ratio when producing fiber by melt-spinning a resin composition composed mainly of polyvinyl chloride-based resin. Preferably, at least one of following (1) to (3) embodiments is included. (1) Melt-spinning uses a full-flight screw having a 2-5 angles cross section in the spiral direction of the screw. (2) Melt-spinning uses a screen mesh having ≤80 μm aperture. (3) The resin composition composed mainly of polyvinyl chloride-based resin contains 0.2-5 pts.mass inorganic stabilizer selected from hydrotalcite and zeolite. COPYRIGHT: (C)2007,JPO&INPIT
