Definitions

  • the present invention relates to a process to provide an intermittently-insulated conductive yarn, said intermittently-insulated yarn and its applications.
  • Certain conductive yarns currently used in wearable technology are either incorporated into a fabric as part of the fabric body (e.g. knitted as part of the fabric body). Therefore, to protect the conductive yarn from the environment (and to prevent shocks the wearer and/or short circuits), the knitted conductive fabric must be encapsulated with an insulating material on both sides. It is difficult to achieve complete encapsulation for such materials and the addition of two layers of encapsulation material on either side of the knitted conductive material results in a conductive material that is significantly increased in thickness even before it is added to a fabric substrate and/or top layer - which requires the use of additional bonding layers or steps. This results in a thick garment that may be uncomfortable for the wearer and which may suffer from a short lifetime as the conductive paths incorporated may remain vulnerable to washing.
  • SS yarns are superior in many aspects of performance (e.g. because of higher conductivity, higher wash durability, low susceptibility to detergents, higher strength etc.). This is because SS yarns have been found to be difficult to work with when laying or embroidering a yarn onto a substrate material.
  • One other type of yarn that has been used involves the use of a yarn that has been fully encapsulated in an insulating material that is then applied to a substrate.
  • a problem with these yarns is that they require the removal of the insulating material in order to be able to form electrical connections, thereby resulting in additional steps to form the desired product.
