Conductive yarn/sewing thread capable of data/signal transmission having an exterior conductive wire, and smart fabric, and garment made therefrom

Abstract

A conductive composite yarn/sewing thread comprising: a) a core formed of at least a first strand of a conductive metal of 40 or higher gauge, and b) at least one inner cover wrapped around the core in a first direction at a rate sufficient to provide substantially complete coverage of the core by the inner cover; c) at least one outer cover wrapped around the at least one inner cover, wherein the outer cover is wrapped in a second direction opposite to a direction of a cover layer on which the outer cover is directly wrapped, at a rate sufficient to provide substantially complete cover of the cover layer on which the outer cover is directly wrapped; wherein one of the inner cover or the outer cover contains a second strand of conductive metal of 40 or higher gauge, and is configured such that a distance between said second strand and said at least first strand is substantially constant; and d) optionally, a lubricant, and a stretch conductive composite yarn, comprising: a core formed from an elastic yarn, and at least one cover layer wrapped helically around the core, wherein the at least one cover layer comprises a natural or synthetic yarn having contained therein a bare conductive metallic strand of 40 or higher gauge; a conductive composite sewing thread therefrom, and use of the yarn/sewing thread in production of a variety of items, including, but not limited to, smart fabrics or smart garments having electrical segments, patterns, or grids therein
