POLYESTER FIBER |
| 摘要 |
An object of the present invention is to improve spinnability, productivity, and tensile strength of a polyester fiber containing poly(3-hydroxybutyrate-co-3-hydroxyhexanoate).;By spinning the polyester resin containing the poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) at a high spinning velocity, the spinnability, productivity, and tensile strength of the polyester fiber can be improved. |

1. A polyester fiber obtained by spinning a polyester resin comprising poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) at a spinning velocity of from 1,500 to 7,000 m/min,
wherein the polyester fiber has a ratio Iβ/Iα of not less than 0.02, where Iα denotes a diffraction intensity from α-crystals, Iβ denotes a diffraction intensity from β-crystals, and an influence on Iα and Iβ caused by an amorphous phase in the polyester fiber is removed when measuring Iα and Iβ. |
