PROBLEM TO BE SOLVED: To provide polyphenylene sulfide fibers which can stably be produced without causing the deterioration of operability and the irregularity of fiber physical properties, even when polyphenylene sulfide resin is spun and drawn with an extruder type extruder without being pelletized. SOLUTION: Provided are the polyphenylene sulfide fibers whose viscoelastic characteristic is a viscosity activation energy of≥22 kJ/mol. COPYRIGHT: (C)2010,JPO&INPIT
