PROBLEM TO BE SOLVED: To provide a polylactic acid fiber excellent in strength and heat resistance. Moreover, the objective of this invention is providing the textiles which consist of this fiber. SOLUTION: The present invention is a fiber composed of poly L lactic acid and poly D lactic acid, has a strength of 4.5 cN / dTex or more, and is a single complex derived from a stereocomplex crystal in a differential scanning calorimeter (DSC) measurement. A polylactic acid fiber having one melting peak and having a melting point of 210 ° C. or higher and a method for producing the same. [Selection figure] None |
