| titleOfInvention | Method for preparing polyglycolic acid fiber |
| abstract | The invention discloses a method for manufacturing polyglycolic acid fiber, which adopts the following processes: pre-treating polyglycolic acid resin, vacuumizing, melting by a screw extruder, metering a melt pump, forcibly filtering, spinning a component, cooling and crystallizing filaments, winding a doffer to form primary filaments, carrying out heat treatment on the primary filaments, and obtaining the polyglycolic acid fiber after the process flow. The product of the invention adopts polyglycolic acid resin with the weight-average molecular weight of more than 60 ten thousand for melt spinning, and the polyglycolic acid has biodegradability, so the polyglycolic acid is widely applied to a plurality of fields such as artificial skin of an animal or human external surgery suture, artificial blood vessels, bone fixation and repair, drug controlled release, erythrocyte carriers and the like. |
