摘要：
A method for producing a polyglycolic acid-based fiber, includes a spinning process of obtaining undrawn yarns by melt spinning a polyglycolic acid-based resin composition, which comprises a polyglycolic acid resin and a polylactic acid resin having a weight average molecular weight of 10×104 to 30×104 in a mass ratio of the polyglycolic acid resin to the polylactic acid resin of 70/30 to 99/1. The method also includes a keeping process of keeping the undrawn yarns and a drawing process of obtaining drawn yarns by drawing the kept undrawn yarns.
