Abstract: A poly(phenylene sulfide) fiber contains 1-10% by weight of a poly(phenylene sulfide) oligomer having a weight-average molecular weight of 5,000 or less, has a difference between a cold crystallization heat quantity (ΔHc) and a crystal melting heat quantity (ΔHm) during temperature rising in DSC, ΔHm−ΔHc, of 25 J/g or larger, and has an elongation of less than 40% and a strength of 3.0 cN/dtex or higher. The poly(phenylene sulfide) fiber has high heat resistance and chemical resistance and high strength and, despite this, has excellent suitability for high-order processing, e.g., thermal shapability, because the amorphous parts thereof have high molecular movability.
