  • the polymeric binder Usable as the polymeric binder are the various synthetic resins of the acrylic, epoxy, phenolic, urethane, melamine, urea, polyester, vinyl and silicone types, the natural and synthetic rubbers, and the mixtures of these.

  • a coating of excessive thickness is not only unnecessary from the standpoint of conductivity but also undesirable from the standpoint of flexibility.
  • a coating containing finely divided silver should have average thickness not exceeding about microns.
  • the coatings containing the finely divided silver in an amount exceeding about 90 percent by weight are in general poor in their tenacity and their adhesiveness to the substrate and hence easily tend to become separated from the substrate during the processing steps and in use.
  • the electrically conductive filaments used in the present invention retain the functional properties of textile fibers and have durability against various conditions that are usually encountered during the manufacture of sewing thread and during their use such as abrasion, repetitive fiexurc, repetitive elongation and relaxation, scouring, dyeing and washing.
  • the conductive filaments of the invention are compatible with the textile fibers which are used in the sewing thread. These conductive filaments can be incorporated into the sewing thread very readily during their manufacture.

  • Reference numeral 1 represents an electrically conductive filament which has been preliminarily twisted together with a yarn 2 consisting of ordinary textile fibers.
  • the sewing thread of the invention can be very easily produced by preliminarily twisting an electrically conductive filament with a yarn consisting of ordinary textile fibers, and then finally twisting the resulting yarn together with one or a plurality of other twisted yarns. It is preferred from the viewpoint of sewability that the electrically conductive filament be given a preliminary twist together with the yarn. This is, however, not restrictive.
  • the sewing thread of the invention can also be made by twisting the electrically conductive filament together with a plurality of preliminarily twisted yarns. in this case, the
  • electrically conductive filament can be twisted together with the preliminarily twisted yarns while the conductive filament is being tensioned, thereby producing a sewing thread in which the electrically conductive filament is not visible from without.
  • An amount of the electrically conductive filament to be contained in the sewing thread of the invention is such that at least one electrically conductive filament is present along the entire length of the sewing thread. If at least one of such an electrically conductive continuous filament is present in the sewing thread along its entire length, the sewing thread has an electrical resistance not in excess of 2,000 megohms/cm.

  • the electrically conductive sewing threads used in the present invention include not only those in which an electric resistance is in the region of an ordinary conductor, but also those in which an electric resistance is very high such as 2,000 mil/cm. it is surprising that a marked antistatic effect is exhibited even when a very small amount ofa sewing thread having such high electric resistance is incorporated. It is not easy to explain the mechanism of prevention of electrification. Generally, a high voltage above 1,000 v. poses the problem of an unfavorable electrification of ordinary organic textile fibers, and a quantity of electrostaticity generated at this time is very small.
