Abstract
A polyphenylene sulfide monofilament is 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 a drum-shaped fiber package includes the wound polyphenylene sulfide monofilament described. The polyphenylene sulfide monofilament has a very small aperture variation rate and is optimal for high-precision filters.
