Abstract:
A method for producing a polyglycolic acid fiber, including: obtaining undrawn yarns by melt spinning a polyglycolic acid resin; keeping the undrawn yarns under a temperature condition of 1 to 20° C.; obtaining drawn yarns by drawing the kept undrawn yarns; and, if necessary obtaining a staple fiber by cutting the drawn yarns.
