Definitions

  • the present invention relates to the area of conductive yarns and conductive sewing threads that can transmit signal or data, and have reduced or eliminated crosstalk, along with products made therefrom, particularly in the area of making smart fabrics and smart garments using the conductive yarn/sewing thread.
  • Such smart fabrics and garments are particularly sought for use in military and sporting applications. In military uses, such smart fabrics are used to track the wearer's biometric readings, as well as for satellite tracking of individuals in the operational theater.
  • Another problem with conductive sewing thread is the need to be able to sew the conductive thread across itself without causing an electrical shor t circuit.
  • signals or data get transmitted via such conductive yarns or sewing threads, there can be interference from ambient radiative processes and sources, or interference in the form of crosstalk between separate conductive yarns or sewing threads within the same fabric or garment which are each transmitting signals. Accordingly, there is a need for such conductive yarns or sewing threads in which the problem of crosstalk or electronic interference has been greatly reduced or even eliminated, in order to have consistent transmission of the data or signals.
  • one object of the present invention is to provide a conductive composite yarn, and particularly a conductive composite sewing thread that enables the production of conductive patterns in a fabric.
  • a further object of the present invention is to provide the conductive composite yarn or sewing thread which is capable of signal or data transmission, wherein by virtue of its construction, the problem of crosstalk has been reduced or eliminated.
  • a further object of the present invention is to provide a smart fabric made using the conductive composite yarn/sewing thread of the present invention.
  • a further object of the present invention is to provide a garment made using the smart fabric of the present invention.
  • a conductive composite yarn/sewing thread comprising:
  • the present invention relates to a conductive composite yarn comprising a central core having at least two strands of a conductive metal of 40 or higher gauge, wherein the at least two strands of conductive metal are configured such that one strand is wrapped around the other strand at a wrap rate of from 1 to 50 turns per inch, wherein the wrapped strand is preferably a ground wire; a cover of one or more strands of a synthetic or natural fiber, which may optionally be a high performance fiber, and an outer cover of a synthetic or natural fiber, such as polyester or nylon strand(s), treated with a suitable bonding agent, and, optionally, with an outer application of a suitable lubricant.
  • the conductive composite yarn is particularly suitable for use as a sewing thread.
  • fiber refers to a fundamental component used in the assembly of yarns and fabrics. Generally, a fiber is a component which has a length dimension which is much greater than its diameter or width. This term includes ribbon, strip, staple, and other forms of chopped, cut or discontinuous fiber and the like having a regular or irregular cross section. “Fiber” also includes a plurality of any one of the above or a combination of the above.
  • high performance fiber means that class of synthetic or natural non-glass fibers having high values of tenacity greater than 10 g/denier, such that they lend themselves for applications where high abrasion and/or cut resistance is important.
  • high performance fibers have a very high degree of molecular orientation and crystallinity in the final fiber structure.
  • filament refers to a fiber of indefinite or extreme length such as found naturally in silk. This term also refers to manufactured fibers produced by, among other things, extrusion processes. Individual filaments making up a fiber may have any one of a variety of cross sections to include round, serrated or crenular, bean-shaped or others.
  • nylon is preferably nylon-6,6.
  • Polyester is preferably polyethylene terephthalate, polypropylene terephthalate or
  • Yarn refers to a continuous strand of textile fibers, filaments or material in a form suitable for knitting, weaving, or otherwise intertwining to form a textile fabric. Yarn can occur in a variety of forms to include a spun yarn consisting of staple fibers usually bound together by twist; a multi filament yarn consisting of many continuous filaments or strands; or a mono filament yarn which consist of a single strand.
  • air interlacing refers to subjecting multiple strands of yarn to an air jet to combine the strands and thus form a single, intermittently commingled strand. This treatment is sometimes referred to as "air tacking.” This term is not used to refer to the process of "intermingling” or “entangling” which is understood in the art to refer to a method of air compacting a multifilament yarn to facilitate its further processing, particularly in weaving processes. A yarn strand that has been intermingled typically is not combined with another yarn. Rather, the individual multifilament strands are entangled with each other within the confines of the single strand.
  • composite yarn refers to a yarn prepared from two or more yarns, which can be the same or different.
  • Composite yarn can occur in a variety of forms wherein the two or more yarns are in differing orientations relative to one another.

The outer cover is then wrapped at a rate sufficient to provide complete coverage of the inner cover, preferably from 4 to 15 tpi, more preferably from 6 to 12 tpi, again depending upon the composite denier of the core/inner cover combination and the denier of the yarn making up the outer cover. The outer cover preferably protects the core and inner cover.
