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.

摘要： 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 contains a polyhydroxyalkanoate, a nucleating agent, and a lubricant, wherein the nucleating agent contains pentaerythritol, and the lubricant contains at least one species selected from the group consisting of behenic amide, stearic acid amide, erucamide, and oleic amide.
