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.

Abstract: An objective is to improve the spinnability and the productivity and increase the tensile strength of a polyester fiber containing polyhydroxyalkanoate. Disclosed is a biodegradable aliphatic polyester fiber containing a polyhydroxyalkanoate, a nucleating agent, and a lubricant, wherein the nucleating agent contains pentaerythritol, and the lubricant contains at least one of behenic amide, stearic acid amide, erucamide, oleic amide, and a combination thereof.
