PROBLEM TO BE SOLVED: To provide a polylactic acid fiber that has not only biodegradability but also sufficient anti-flexural wear resistance, shows good process passing in the steps of spinning, drawing, and post-processing, has excellent fiber properties such as high strength and elongation, therefore can suitably be used not only as clothes but also as an industrial material. SOLUTION: The polylactic acid fiber is composed of polylactic acid polymer as a main component and a resin powder of polytetrafluoroethylene in an amount of 0.01-15 mass% based on the total fiber mass.
