Claim:
A method of producing a plied silver yarn, comprising the steps of: (a) preparing a silver wire that is produced by casting silver or a silver alloy into a wire rod through directional solidification and making the wire rod into the silver wire having a diameter ranging from 0.015 mm to 0.05 mm through a pulling process; (b) obtaining a first plied silver yarn by plying at least one strand of the silver wire with a fiber yarn made from natural fiber or synthetic fiber, and twisting the silver wire and the fiber yarn to form the first plied silver yarn; and (c) producing a second plied silver yarn by taking the first plied silver yarn as a core yarn and winding a second fiber yarn as a covering yarn around the first plied silver to form the second plied silver yarn, the second fiber yarn being formed of natural fiber or synthetic fiber.
