Abstract

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.
