| Abstract: | Poly L-lactic (PLLA) acid and polyglycolic acid (PGA) were composite-spun at the ratio of 85/15 and 70/30 to produce two types of sheath-core composite fibers. The thermal and mechanical properties and crystallinity of the resulted fiber were studied. The results showed that no esterification occurred during the melting spinning of PGA and PLLA. The strength of the fiber was increased with the increase of draw ratio. The crystallinity and orientation degree were improved. The resulted sheath-core composite fibers showed compact structure without any gap and holes. |
