PROBLEM TO BE SOLVED: To stably obtain a nanofiber from a polyamide in a mutually dispersed state without causing reaggregation. SOLUTION: The polymer alloy fiber is a sea-island structural fiber composed of a polymer of at least two or more components in which the sea component is a polylactic acid, the island component comprises a poly(ε-capronamide) as a main component, has a polymer viscosity 100-250 Pa s higher than that of the sea component at 220-250°C, 50-300 nm average fiber diameter and 10-30% dispersion of fiber diameter. The method for producing the polymer alloy fiber and the nanofiber are provided. COPYRIGHT: (C)2007,JPO&INPIT
