Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a high performance machine sewing thread which is comprehensively superior to conventional filament machine sewing threads and spun machine sewing threads by improving the strength of a spun machine sewing thread which is inferior to a filament machine sewing thread.SOLUTION: A high strength spun machine sewing thread Y includes a composite twisted yarn having a mean fiber length of 300 to 600 mm, comprises stretch broken staple fibers of a synthetic fiber with substantially no crimp, and is obtained in such a manner that a bundle Y of the staple fibers is entangled and wound by a high pressure air injection and further subjected to a primary twisting in S direction, two or more of the primary twisted bundles Y are aligned and subjected to a secondary twisting in a Z direction, and an oil is attached thereon.
