Moreover, although the monofilament can be adopted as the non-conductive ground yarn 31, a multifilament or a spun yarn, which is an aggregate of a plurality of single fibers, can be preferably used rather than a monofilament.

  In addition, since the conductive fabric 1 according to the present invention is used by being connected to an external device such as an electrocardiographic device or a myoelectric device, the region surrounded by the alternate long and short dash line in FIG. It is set as the connection part 4 to which the connection terminal Z (conductive to-be-adhered body) to be written is piled up and fixed.

  In addition, mineral oil softener (e) usually reduces the intermolecular action force of rubber during roll processing, facilitates processing, and disperses carbon black, white carbon, etc. blended as a filler. It is a high-boiling petroleum fraction used for the purpose of increasing the flexibility and elasticity by reducing the hardness of vulcanized rubber, and is classified into paraffinic, naphthenic, aromatic and the like.

  Various methods can be adopted as a method of impregnating a predetermined portion (a portion corresponding to the connecting portion 4) of the conductive fabric 1 with the resin adhesive as described above. For example, the resin adhesive composition formed into a sheet is placed in a region corresponding to the connection portion 4 in the conductive fabric 1, and the connection terminal in the external device is placed on the resin adhesive formed into the sheet. Z (conductive adherend) can be placed and heat-pressed from above the connection terminal Z (adherence Z). In addition, although the resin adhesive formed into a sheet may be configured in a film shape, it is preferable to configure it in a non-woven fabric shape from the viewpoint of maintaining stretchability in the connection portion 4 of the conductive fabric 1.

  By performing the heat press, the sheet-like resin adhesive interposed between the conductive fabric 1 and the adherend Z is dissolved and flows toward the inside of the conductive fabric 1. The conductive fabric 1 and the adherend Z are connected and fixed by the adhesive action of the resin adhesive 5 impregnated in the knitted fabric structure in the conductive portion 2 and the nonconductive portion 3. Here, the resin adhesive impregnated in the conductive fabric 1 is not only in the knitted fabric structure in the conductive portion 2 and the nonconductive portion 3, but also between the ground yarn 31 and the ground yarn 31, between the ground yarn 31 and the conductive yarn 21. Between the conductive yarn 21 and the conductive yarn 21, and when the ground yarn 31 and the conductive yarn 21 are configured as an aggregate of single fibers such as multifilaments, they are present between the short fibers. Will be.

  Further, when attention is paid to the conductive yarn 21 that constitutes the conductive portion 2 in the conductive fabric 1 and is disposed on the exposed surface side (the adherend Z side) of the fabric, FIGS. As shown in the schematic cross-sectional view of FIG. 3, the sheet-like resin adhesive 5 before being melted disposed above the top of the conductive yarn 21 (FIG. 3) is melted by heating with a heat press and indicated by an arrow. Thus, while flowing downward, the adherend Z is pushed from the vicinity of the top of the conductive yarn 21 by the movement of the adherend Z (FIG. 4), and is disposed on the exposed surface side (the adherend Z side). The electrically conductive yarn 21 and the adherend Z are in direct contact with each other, and are connected and fixed to obtain an electrically connected state (FIG. 5).

  Further, the pressing force, heating temperature, pressurizing time, and heating time at the time of heat press may be set as appropriate. For example, by applying a relatively large pressing force, as shown in the schematic cross-sectional view of FIG. In addition, it is preferable that the cross-sectional shape of the conductive yarn 21 constituting the conductive portion 2 and at least the portion in contact with the adherend Z is a flat shape compressed in the pressing direction, that is, Regarding the cross-sectional shape of the conductive yarn 21 portion in contact with the adherend Z, the dimension along the direction perpendicular to the overlay direction of the adherend Z (the dimension in the left-right direction in FIG. 6) is the dimension along the overlay direction. It is preferable to have a flat shape that is larger than (the vertical dimension in FIG. 6). It should be noted that the conductive yarn 21 has a predetermined shape depending on the shape retention of the cured resin adhesive by curing the resin adhesive while lowering the heating temperature while applying a pressure sufficient to obtain such a flat shape. The cross-sectional shape in the portion maintains the above-described flat shape.

  As described above, the conductive fabric 1 according to the present invention is connected and fixed in a state where the conductive adherend Z is in direct contact with the conductive portion 2 in at least a part of the region where the conductive portion 2 is disposed. It has a structure that is impregnated with a resin adhesive. Therefore, the conductive adherend Z and the conductive portion 2 in the conductive cloth 1 can be conducted with an adhesive having no conductivity without using a conductive adhesive as in the prior art. The selectivity with respect to the kind of the agent is widened, and it becomes very versatile. Further, the impregnated resin adhesive 5 functions as a member for coating the conductive yarn 21 around the conductive yarn 21 constituting the conductive portion 2 in the connection portion 4 with the adherend Z, and adheres to the adherend Z. A strong adhesive action with the body Z is also exhibited. Therefore, it is possible to effectively prevent the conductive yarn 21 at the connecting portion between the adherend Z and the conductive portion 2 from being oxidized and the metal film of the conductive yarn 21 from falling off, and suppress the deterioration. Thus, it is possible to maintain a good conduction state between the adherend Z and the conductive portion 2.

  In addition, the conductive fabric 1 according to the present invention does not need to separately prepare a resin adhesive when the adherend Z is installed again after the adherend Z is removed and washed, for example. The resin adhesive 5 impregnated in the conductive fabric 1 can be reused to connect and fix them. That is, after the adherend Z is superimposed on the connection portion 4, the resin adhesive 5 already impregnated in the conductive fabric 1 is dissolved again by applying heat press to the overlapped portion, and the adherend Z Can be fixed to the conductive fabric 1.

  In addition, the conductive portion 2 of the conductive fabric 1 according to the present invention has a knitted fabric structure made of conductive yarn 21, and the non-conductive portion 3 similarly has a knitted fabric structure made of ground yarn 31. It is configured. By adopting such a structure, the dissolved resin adhesive is easily impregnated into the interior of the fabric, and the impregnated resin adhesive 5 can be satisfactorily held, and the dissolved resin adhesive is adhered to the adherend Z. It is possible to suppress a large movement to the side opposite to the side on which is provided.

  In addition, as described above, with respect to the cross-sectional shape of the conductive yarn 21 portion in contact with the adherend Z, the dimension along the direction perpendicular to the overlapping direction of the adherend Z (the dimension in the left-right direction in FIG. 6) is By making the flat shape larger than the dimension along the superposition direction (the vertical dimension in FIG. 6), the contact area between the conductive part 2 and the adherend Z increases, and the conductive part 2 It is possible to maintain an even better electrical connection state between and the adherend Z. In addition, since the contact interface between the conductive part 2 and the adherend Z becomes a relatively flat shape, for example, when the adherend Z is once removed from the conductive part 2, the conductive part exposed to the outside. The area of 2 can be increased. Therefore, when the adherend Z is attached to the conductive portion 2 by placing the adherend Z on the conductive portion 2 and performing heat press again, there is also an advantage that it is easy to obtain a good conduction state. Become.

It is good also as a body and it is good also considering the said part as the electroconductive part 2. FIG. Further, by embroidering a conductive thread 21 such as a metal wire or a metal adherend (plated wire) on a predetermined region of the fabric body knitted and knitted using the nonconductive ground yarn 31, the predetermined region May be configured as a conductive fiber structure, and the portion may be the conductive portion 2.

  In the above-described embodiment, the resin adhesive 5 impregnated in the conductive fabric 1 has been described in the above embodiment as being preferably used as a hot-melt resin adhesive containing a modified polyolefin elastomer.

For example, a powdery or granular resin adhesive may be applied to the region corresponding to the connection portion 4 in the conductive fabric 1 and the connection terminal Z (conductive covering) of the external device.

Although illustrated about the method of heat-pressing by interposing the resin adhesive between the area | region corresponding to the part 4, and the connection terminal Z (conductive to-be-adhered body) of an external apparatus, it does not specifically limit to such a method. . For example, after overlapping one surface of the region corresponding to the connection portion 4 in the conductive fabric 1 and one surface of the connection terminal Z (conductive adherend) of the external device, the connection portion 4 in the conductive fabric 1 On the other side of the corresponding area, a hot-melt type resin adhesive such as a sheet, powder or granule is placed and pressed while heating the resin adhesive. The cloth 1 may be impregnated to connect the conductive cloth 1 and the connection terminal Z. In addition, after overlapping one surface of the region corresponding to the connection portion 4 in the conductive fabric 1 and one surface of the connection terminal Z (conductive adherend) of the external device, the connection portion 4 in the conductive fabric 1 After applying a hot-melt type resin adhesive that has been preheated and formed into a liquid state, or a liquid moisture-curing type, energy-ray-curing type, or rewet-type resin adhesive on the other side of the corresponding region The conductive fabric 1 is impregnated into the conductive fabric 1 by pressing, and if necessary, the resin fabric is cured by applying moisture or irradiating energy rays, so that the conductive fabric 1 and the connection terminal Z May be connected.
