Abstract
A method for producing an undrawn polyglycolic acid-based resin yarn, including: a discharge step of discharging a molten polyglycolic acid-based resin through a spinneret, to thereby form a fibrous polyglycolic acid-based resin; a keeping step of keeping the fibrous polyglycolic acid-based resin for 0.0012 seconds or more after the discharge in an atmosphere having a temperature of not lower than 110.5° C. but not higher than a melting point of the polyglycolic acid-based resin; and a cooling step of cooling the fibrous polyglycolic acid-based resin obtained in the keeping step, to thereby obtain an undrawn polyglycolic acid-based resin yarn.
