A polymer alloy fiber includes a polymer alloy consisting of a polylactic acid resin (A), a polyolefin resin (B), and a compatibilizer (C), wherein the compatibilizer (C) is an acrylic elastomer or an styrene elastomer containing at least one functional group selected from the group consisting of anhydride, carboxyl, amino, imino, alkoxysilyl, silanol, silyl ether, hydroxyl, and epoxy, and the polylactic acid resin (A) and the polyolefin resin (B) are island and sea components, respectively, to form a sea-island structure in the morphology of the polymer alloy. |
