摘要： The obtained hollow fiber membrane has high water permeability, and has, when used as a humidifying membrane, a linear relationship between supply humidity and humidification amount. Therefore, the hollow fiber membrane is effectively used, for example, as a humidifying membrane for fuel cells. The method for producing a polyphenylsulfone hollow fiber membrane according to present invention can provide a humidifying membrane that suppresses segregation and crosslinking of hydrophilic polymers associated with the operation of the humidifying membrane, and that prevents the deterioration of humidification performance due to the operation. In addition, the producing method of the present invention can produce a polyphenylsulfone hollow fiber membrane for humidifying membranes, wherein the hollow fiber membrane has high water permeability, and has, when used as a crosslinked humidifying membrane, a linear relationship between water vapor supply humidity and humidification amount.

摘要： 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.
