Definitions

  • the present invention relates to an electrically conductive fabric, and a manufacturing method, and more specifically to an electrically conductive fabric, and a manufacturing method, wherein part of electrically conductive wire knitted together into fabric is selectively exposed to the outside of the fabric to perform the tying of electrically conductive wires and the connection of various elements and modules quickly and conveniently, so that workability and productivity can be improved.
  • fabrics such as knitted fabrics or woven fabrics (below to be described commonly as fabrics) that are used to manufacture bed covers, curtains, clothes, etc. are woven by natural fiber yarn or man-made fiber yarn, and their kinds are various, and they have properties and characteristics unique in their own way according to the purpose of use, such as heat conservation, absorptivity, stretchability, etc.
  • fabrics in demand are those that can conduct electric current for various electric appliances to be installed for convenient use or those that perform heating action or cooling action by themselves.
  • fabrics can realize beds, intelligent clothes, etc. which are light and thin and can be used regardless of season.
  • Such a planar heating unit woven by carbon fiber yarn performs heating action when power is supplied, so it can be applied to the goods that need warming action, but it has a disadvantage that it cannot be applied to bed material that needs a cushioning function or clothes that need stretchability and freedom of motion because it does not have stretchability at all due to the characteristics of carbon fiber yarn. And if friction force is applied continuously while it is being used, the fine structures of carbon fiber yarn become loosened and damaged or minute electrical sparks are generated, so it was not possible to secure sufficient durability and safety.
  • smart clothes equipped with electronic appliances such as a wearable computer and an MP3 player need conductive wires for electrically connecting operating buttons, power supply unit, various electronic elements, etc. and for transmitting electric signals, but a planar heating unit manufactured with carbon fiber yarn has a limit that it cannot perform such functions at all.
  • a method of stitching an extra conductive wire such as copper wire to clothes can be suggested, but because a copper wire does not have any stretchability at all, the freedom of motion and wearability as clothes are not good.
  • Another disadvantage is that it is very inconvenient to use it because the conductive wire and control buttons installed in the clothes have to be removed to wash them.

  • the electrically conductive fabric 1 is a fabric selectively comprising electrically conductive wires for heating that are formed in planar cloth and performs a heating action when electric current is supplied, electrically conductive wires for conduction of electric current and electrically conductive wire for signal transmission for transmitting electric signals.
  • This fabric includes the multiple strands of warp 11 arranged lengthwise, plural strands of weft 12 knitted in the direction perpendicular to the warp 11, and plural strands of electrically conductive wires 13 arranged lengthwise and woven.
  • the electrically conductive fabric 1 is characterized by being repetitively composed of the electrically conductive wire weaving sections a in which the electrically conductive wire 13 is knitted with the warp 11 and/or weft 12 to be monolithically bound to the electrically conductive fabric as shown in Figs. 1a and 1b , and electrically conductive wire exposing sections b in which the electrically conductive wire 13 is not knitted with the warp and/or weft but is exposed to the outside of the electrically conductive fabric by a predetermined length.
  • the warp 11 is composed by applying common fiber yarn for the case of composing the electrically conductive fabric 1 so as not to have stretchability lengthwise, and by applying stretchable fiber yarn such as span yarn for the case of composing the electrically conductive fabric 1 so as to have stretchability lengthwise.
  • the weft 12 is composed by applying common fiber yarn; in case high strength is needed, it is composed by applying high-tension fiber yarn such as Kevlar yarn and aramid yarn.
  • the electrically conductive wire 13, as shown in enlargement in Fig. 1a is composed by applying the one that is wound and formed into one bundle to sheathe plural strands of insulated electrically conductive yarn 131 with plural strands of fiber yarn 132.
  • the electrically conductive yarn 131 can embodied by selecting yarns having various materials and diameters if they can conduct electric current, but in the present example, they were selected from metal yarns (commonly called enamel wires) in which insulated sheathed layers are formed on stainless wires, titanium wires, copper wires, etc. having diameters of tens to hundreds of micrometers ( ⁇ m) and plural strands of fiber yarn 132 are wound on the outer circumference as an outer layer.

  • the support wires 15 are woven on the left and right of the electrically conductive wire 13 to bind it to the warp and weft so as to prevent deformation. Namely, if the electrically conductive wire 13 is composed of metal yarn, it is protruded to the surface or back of the electrically conductive fabric 1 due to the difference in flexibility from the fiber yarn supplied as the weft and warp. At this time, since the support wires 15 perform the function of holding the weft and warp on the left and right as reinforcement wires, the twist of the electrically conductive wire can be prevented. For this purpose, it is preferable that the support wire 15 has a plurality of fiber yarns twisted and a diameter (denier) greater than the weft and warp.

  • Fig. If is a view showing a third modification of the electrically conductive fabric according to the first example, wherein the cross section of the electrically conductive wire weaving section is illustrated, and the electrically conductive wire exposing section is omitted.
  • the electrically conductive fabric is composed in such a way that it has electrically conductive wire weaving sections a in which the electrically conductive wire is embedded in the planar body and electrically conductive wire exposing sections b in which the electrically conductive wire is exposed to the outside of the planar body, by making the electrically conductive wire 13 bound selectively to the warp 11 and/or weft 12 by an extra binding-and-releasing weft 14.
  • the binding-and-releasing weft 14 is supplied together when the electrically conductive wire 13 is woven to be knitted to the warp and/or weft so that it is bound thereto in the electrically conductive wire weaving sections a, while the electrically conductive wire 13 is knitted to the warp and/or weft so as not to be bound to the electrically conductive fabric 1 in the electrically conductive wire exposing section b.

  • the electrically conductive wire can be woven in such a way that it can be arranged in a straight form structure or wave form structure along the warp direction in the same manner as in the first example mentioned above, only the one arranged in the wave form structure will be described.
  • the electrically conductive fabric 1' includes multiple strands of warp 11 arranged lengthwise, multiple strands of weft 12 knitted in the direction perpendicular to the warp 11, and plural strands of electrically conductive wires 13 arranged lengthwise and woven.
  • the weft 12 includes a first warp-knitting weft 12a that is knitted with the warp 11 at the position corresponding to the inside of the electrically conductive wire 13, a second weft 12b (see Fig.
  • the binding-and-releasing weft 12c is composed by being knitted such that the electrically conductive wire is bound together with the warp 11 and the first warp-knitting weft 12a, in the electrically conductive wire weaving section a (see Figs. 2a and 2b ), and by being knitted within the range where the electrically conductive wire 13 is not bound with the warp 11 and the first warp-knitting weft 12a, in the electrically conductive wire exposing section b (see Figs. 2a and 2c ).
  • the electrically conductive wire 13 is woven so as to make a waveform structure, and on both sides of the placement path of the electrically conductive wire 13, it is possible to compose in such a way that the support yarn 15 is woven to support the electrically conductive wire, in a way similar to the first example.
  • Fig. 3 is a block diagram of the process for describing the manufacturing method of the electrically conductive fabric according to the first example.
