Zusammenfassung:	PURPOSE: To variously control a phase separation structure of a fiber with good reproducibility in a stable spinning step by keeping a partially compatible two-component polymer blend in a compatible state, melt spinning the polymer blend and manifesting the phase separation structure in a step after the spinning. CONSTITUTION: This polymer blend fiber is obtained by melt spinning a partially compatible two-component polymer blend (e.g. a polymer blend having an upper critical consolute temperature type phase diagram) in a compatible state and manifesting a phase separation structure in a step after the spinning by a physical or a chemical means. Thereby, a nonuniform phase structure of
