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.
