Abstract:
An assembled yarn comprises a first yarn and a second yarn. The first yarn comprises a core yarn and a first wrap yarn. The core yarn comprises a spun yarn, wherein the spun yarn comprises a blend of fibers, wherein the blend of fibers comprises first electrically conductive fibers. The first wrap yarn comprises or consists out of one or a plurality of metallic filaments. The first wrap yarn is wrapped around the core yarn with at least 300 turns per meter. The second yarn comprises second electrically conductive fibers. The second yarn is wrapped around the first yarn; or the second yarn is ply-twisted with the first yarn thereby forming a plied yarn. The assembled yarn can be used in electromagnetic shielding fabrics.
