Biodegradable complex fiber and method for producing the same |
摘要 |
A biodegradable complex fiber which retains excellent biodegradability and hydrolyzability and has high strength and high melting temperature suitable for practical use and a method for producing the biodegradable complex fiber are provided. The biodegradable complex fiber comprises at least one polymer material selected from the group consisting of a polyglycolic acid, a poly(glycolic acid-co-lactic acid) and polylactic acid as a core component or as a shell component and a polymer material of poly(3-hydroxybutyric acid) groups or a polymer material of an aliphatic polyester consisting of a dibasic acid and a diol as a shell component or as a core component. The method comprises producing the biodegradable complex fiber by melt spinning.
