Beschreibung
Zusammenfassung:	The present invention takes the forms of: (1) a polyphenylene sulfide monofilament characterized by having a continuous heat-shrinking stress variation of at most 5% and a size uniformity (U%, Normal value) of at most 1.2%; and (2) a drum-shaped fiber package wherein the polyphenylene sulfide monofilament described in (1) has been wound. Provided is a polyphenylene sulfide monofilament having a very small aperture variation rate and being optimal for high-precision filters.
