  • Method for producing polyglycolic acid fiber
    Patent number: 8840823
    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.

  • SEPARATION-RESISTANT GAS-BARRIER LAMINATE
    Publication number: 20110123744
    Abstract: In a gas-barrier laminate having a layer structure of aromatic polyester resin/polyglycolic acid resin/aromatic polyester resin, a small amount of an aromatic polyester resin polymerized with a germanium compound (catalyst) is blended to the polyglycolic acid resin forming the core layer, thereby surface-roughening the polyglycolic acid resin layer. As a result, the peeling resistance between the polyglycolic acid resin/aromatic polyester resin layers is practically improved while maintaining a good gas-barrier property.
