PROBLEM TO BE SOLVED: To provide a global environmental type covered elastic yarn having good dyeability, and durability, and carbon neutral characteristics by using a polylactic acid-polyamide sheath-core conjugated yarn, and to provide a leg knit, and stockings using the covered elastic yarn. SOLUTION: The covered elastic yarn uses a core yarn using elastic fibers, and a part of wound yarns using sheath-core conjugated fibers. In the covered elastic yarn, the core component is a polyamide, and the sheath component is the sheath-core conjugated fibers of polylactic acid. The sheath-core conjugation ratio is (30/70) to (60/40) wt.%. The sheath component covers the outer peripheral surface of the fibers. COPYRIGHT: (C)2009,JPO&INPIT
