| abstract |
The present invention relates to a biodegradable polyester blend composition, a method for preparing the same, and a fiber prepared therefrom, and more particularly, to a polyester blend composition comprising an aromatic acid including a phenylene group and an aliphatic acid including a carboxylic acid group. Polylactic acid (PLA) and glycidyl methacrylate or maleic hydride are grafted to a polyester prepared by mixing and esterifying and polycondensing an acid component, a sulfonic acid metal salt and a diol component having 2 to 14 carbon atoms. The present invention provides a biodegradable polyester blend composition prepared by mixing the prepared polyethylene oxide, a method for preparing the same, and a fiber produced therefrom. |
