Benefits of technology

[0018]According to the electrically conductive fabric and the manufacturing method and apparatus thereof of the present invention, there is provided an effect of being able to carry out tying or connecting work quickly and conveniently by forming electrically conductive wire exposing sections for the portions for tying electrically conductive wires or connecting various elements or modules, since they are provided with electrically conductive wire weaving sections where electrically conductiv

Problems solved by technology

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.
In addition, 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.
As a way for solving such problems, a method of stitching an extra conductive wire such as copper

first embodiment

[0045]Next, FIG. 1d is a view showing the first modification of the electrically conductive fabric according to the present invention; as shown in the drawing, the electrically conductive fabric includes support wires 15 which are woven along the placement path of the electrically conductive wire.

[0046]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 twiste...

second embodiment

[0053]With reference to FIGS. 2a to 2c and FIG. 2d, the electrically conductive fabric 1′ according to the present invention 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. At this time, 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. 2d) for knitting the warp that is knitted with the warp 13 so as to provide a feeding free zone in the range of width corresponding to the placement width of the electrically conductive wire 13 at the position corresponding to the outside of the electrically conductive wire 13, and a binding-and-releasing weft 12c (see FIGS. 2b and 2c) that is knitted with the warp so as to selectively bind the electrically conductive wire 13 at t...
