Abstract (en)

[origin: EP2246463A1] [Abstract] The object of the invention is to provide a polyphenylene sulfide fiber with a large single-filament fineness that does not require special production equipment and serves as industrial material for uses where high rigidity is needed, and also provides a low-cost process to produce said polyphenylene sulfide fiber with high spinnability. A polyphenylene sulfide fiber with a single-filament fineness of 10 to 50 dtex and a tenacity of 4.5 to 6 cN/dtex. A polyphenylene sulfide fiber production method wherein an aqueous lubricant is attached to the surface up to 0.1 to 1 wt% and subsequently a anhydrous lubricant is attached to the surface so that the total weight of the surface-attached oil will account for 0.5 to 2 wt%.
