By the way, the above-mentioned transmission sheet includes two conductive layers having conductivity and a non-conductive layer having no conductivity disposed between the two conductive layers in order to transmit power or information. is common. It is desired that the two conductive layers are reliably insulated.

Therefore, there is a demand for a technique capable of reliably insulating two conductive layers included in the transmission sheet.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in the drawings, the same reference numerals are given to the same or corresponding parts.

(Embodiment 1)
First, the configuration of a fiber structure 1000 according to an embodiment of the present invention will be described with reference to FIG. The fiber structure 1000 is a structure composed of fibers used for a transmission sheet that supplies power or transmits information. In this embodiment, the transmission sheet is assumed to be a wearable transmission sheet that supplies power to a sensor worn on the human body and transmits information transmitted and received by the sensor. Note that the transmission sheet may be used as a fabric for clothes, or may be used by being attached to existing clothes. The transmission sheet comprises two electrically conductive layers and a non-conductive layer disposed between the two electrically conductive layers for power supply and information transmission. . In addition, the transmission sheet is desired to be made of a highly flexible material so that it can be easily worn on the human body. Therefore, in the present embodiment, an example in which a transmission sheet is configured with a fiber structure 1000 including conductive yarns and non-conductive yarns will be described.

As shown in FIG. 1, a fiber structure 1000 includes a fiber structure 100 as a first fiber structure and a fiber structure 200 as a second fiber structure. The fiber structure 100 includes a base fabric 110 and a conductive layer 120. As shown in FIG. The base fabric 110 is a fabric composed of non-conductive yarns having no conductivity, and serves as the base of the conductive layer 120 . The conductive layer 120 is a layer made of a conductive thread having conductivity. The conductive layer 120 is formed by inserting conductive threads into the base fabric 110 . In other words, the fiber structure 100 is formed from the non-conductive threads forming the base fabric 110 and the conductive threads forming the conductive layer 120 . In the present invention, insertion means a state in which the conductive yarn is woven into the base fabric 110 and integrated as the base fabric 110, a state in which the conductive thread is woven into the base fabric 110 and integrated as the base fabric 110, and a state in which the conductive thread is integrated into the base fabric 110. exists in the base fabric 110 but is not integrated with the base fabric 110.

Fiber structure 100 has a front surface 130 and a back surface 140 . Surface 130 is the surface on which conductive layer 120 is disposed. In FIG. 1, the surface 130 is the surface with the larger coordinate in the Z-axis direction of the two surfaces of the fiber structure 100 . The back surface 140 is the surface on which the conductive layer 120 is not arranged. The back surface 140 is the surface with smaller coordinates in the Z-axis direction of the two surfaces of the fiber structure 100 . In this embodiment, the Z-axis direction is the vertical direction, the X-axis direction is the direction orthogonal to the Z-axis direction, and the Y-axis direction is the direction orthogonal to the X-axis direction and the Z-axis direction. and

The conductive layer 120 is exposed only on one side of the two sides of the fiber structure 100 . In this embodiment, the conductive layer 120 is exposed only on the surface 130 and not exposed on the back surface 140 . In this embodiment, a state in which a certain portion is exposed is referred to as a certain portion being exposed. In other words, a part is exposed if it is not only visible, but it also protrudes relative to other parts. In other words, if a portion is visible, but is recessed more than other portions, it is not said that a portion is exposed.

Therefore, the conductive layer 120 is visible when the fiber structure 100 is viewed from the positive direction in the Z-axis direction. In addition, the coordinates in the Z-axis direction of the visible portion of the conductive layer 120 are larger than the coordinates in the Z-axis direction of the base fabric 110 surrounding the visible portion. On the other hand, the conductive layer 120 is basically invisible when the fiber structure 100 is viewed from the negative direction in the Z-axis direction. However, the conductive layer 120 may be visible when the fiber structure 100 is viewed from the negative direction in the Z-axis direction. In this case, it is assumed that the coordinates in the Z-axis direction of the visible portion of the conductive layer 120 are larger than the coordinates in the Z-axis direction of the base fabric 110 surrounding the visible portion.

As shown in FIG. 2, in the present embodiment, when the fiber structure 100 is viewed from above, that is, when the fiber structure 100 is viewed from the positive direction in the Z-axis direction, the pattern of the conductive layer 120 is a lattice pattern. shall be However, the pattern of the conductive layer 120 is not limited to the lattice pattern, and is appropriately adjusted according to the use of the transmission sheet, power supply voltage, signal voltage, signal frequency, maximum transmission distance, and the like.

The fiber structure 200 basically has the same configuration as the fiber structure 100 . That is, the fiber structure 200 includes the base fabric 210 and the conductive layer 220. As shown in FIG. The base fabric 210 has the same configuration as the base fabric 110 . Also, the conductive layer 220 has the same configuration as the conductive layer 120 . Fiber structure 200 has a front surface 230 and a back surface 240 . Surface 230 is the surface on which conductive layer 220 is disposed. The back surface 240 is the surface on which the conductive layer 220 is not arranged. That is, conductive layer 220 is exposed only on front surface 230 and not on back surface 240 .

Here, the fiber structure 1000 is formed by fixing the back surface 140 of the fiber structure 100 and the back surface 240 of the fiber structure 200 . The fixing method can be adjusted as appropriate. For example, a fixing method such as bonding with an adhesive, bonding with a double-sided tape, or sewing with a non-conductive thread can be adopted. In this embodiment, the insulation between the back surface 140 and the back surface 240 is not ensured by the presence of an adhesive or double-sided tape. The fiber structure 1000 has a configuration in which the conductive layer 120 provided in the fiber structure 100 and the conductive layer 220 provided in the fiber structure 200 are insulated by the base fabric 110 and the base fabric 210 . Therefore, power can be supplied by applying a power supply voltage between the conductive layers 120 and 220 . Information can be transmitted by applying a signal voltage between the conductive layer 120 and the conductive layer 220 .

Here, if the conductive layer 120 and the conductive layer 220 are in contact with each other, not only is power supply and information transmission impossible, but also a large current may flow to generate heat, which is not preferable. Therefore, in this embodiment, the fiber structure 1000 is formed so that the conductive layer 120 and the conductive layer 220 do not come into contact with each other. That is, the fiber structure 100 is formed such that the conductive layer 120 is exposed on the surface 130 and the conductive layer 120 is not exposed on the back surface 140 . Similarly, fiber structure 200 is formed such that conductive layer 220 is exposed on front surface 230 and conductive layer 220 is not exposed on back surface 240 . An example in which the fiber structure 100 is formed such that the conductive layer 120 is exposed only on the surface 130 will be described below.

First, the conductive thread and the non-conductive thread will be described. A conductive yarn is a yarn that contains a conductor, and a non-conductive yarn is a yarn that does not contain a conductor. A conductor is, for example, a substance having a specific resistance (also referred to as “volume resistivity”) of less than 10 ⁸ Ω·cm. The conductive thread may be a metal fiber made of metal such as copper or stainless steel, or may be a carbon fiber made of carbon. The conductive thread may also be a synthetic fiber coated with a metal by sputtering or plating. Alternatively, the conductive thread may be a thread obtained by kneading a conductive material such as metal powder or a conductive polymer into a synthetic fiber. Synthetic fibers are, for example, polyester-based, polyamide-based, polyolefin-based, polyacrylonitrile-based, polyvinyl alcohol-based fibers, and the like.

The fiber form of the conductive yarn may be monofilament, multifilament, spun yarn obtained by spinning staple fibers, etc., as long as the conductivity can be secured, and mixed yarn, blended yarn, etc. can also be used. When emphasizing the stability of the resistance value, it is preferable to adopt a monofilament or a multifilament having a small number of filaments. On the other hand, when the flexibility is emphasized, it is preferable to adopt a multifilament having a large number of filaments. Moreover, the cross-sectional shape of the fibers constituting the conductive yarn may be any shape such as circular, elliptical, and polygonal. Moreover, the fibers that constitute the conductive yarn may have a hollow portion.

Non-conductive yarns are yarns of natural, synthetic, semi-synthetic, inorganic fibers and the like. In order to impart excellent stretchability to the knitted fabric, it is preferable to use elastic yarns as part of the non-conductive yarns. The elastic yarn may be a single elastic fiber, or may be a textured yarn in which elastic fibers are covered with non-elastic fibers. The elastic fibers are, for example, polyurethane-based synthetic fibers or polyether-ester elastomer-based synthetic fibers. Inelastic fibers are, for example, polyester-based or polyamide-based synthetic fibers. The fiber form of the non-conductive yarn may be monofilament, multifilament, spun yarn obtained by spinning staple fibers, or the like, and mixed yarn or blended yarn may also be used. Moreover, the cross-sectional shape of the fibers constituting the non-conductive yarn may be circular, elliptical, polygonal, or any other shape. Moreover, the fibers constituting the non-conductive yarn may have a hollow portion.

In this embodiment, non-conductive yarns are used as the yarns forming the base fabric 110, and conductive yarns are used as the insertion yarns. The insertion thread is inserted by jacquard, for example. When the base fabric 110 is a knitted fabric, the wale density is preferably 10-25/inch, more preferably 15-20/inch, and most preferably 18/inch. Further, when the base fabric 110 is a knitted fabric, the course density is preferably 40-90/inch, more preferably 50-76/inch, and most preferably 66/inch.

Next, with reference to FIG. 3, the arrangement of the conductive threads when the pattern of the conductive layer 120 is a lattice pattern will be described. In this embodiment, the conductive thread 14 and the conductive thread 15 are used as the conductive thread. In addition, when collectively referring to the conductive thread 14 and the conductive thread 15, they are simply referred to as "conductive thread". It is also assumed that the warp threads extend in the Y-axis direction, and the weft threads extend in the X-axis direction. As shown in FIG. 3, the conductive thread 14 extends linearly in any direction parallel to the X-axis direction (for example, the positive direction in the X-axis direction), and then extends in another direction parallel to the X-axis direction. Extending back in a straight line (eg, in the negative direction in the X-axis direction) forms a conductive layer in the X-axis direction. Also, the conductive thread 14 forms a conductive layer in the Y-axis direction by extending zigzag in the positive direction in the Y-axis direction while swinging in the X-axis direction.

The conductive thread 15 extends linearly in any direction parallel to the X-axis direction (e.g., negative direction in the X-axis direction), and then extends in another direction parallel to the X-axis direction (e.g., in the X-axis direction (positive direction) to form a conductive layer in the X-axis direction. Also, the conductive thread 15 forms a conductive layer in the Y-axis direction by extending zigzag in the positive Y-axis direction while swinging in the X-axis direction. The conductive thread 14 and the conductive thread 15 are woven at the same time, but the direction of advance in the X-axis direction is opposite. That is, the movement of the conductive thread 14 and the movement of the conductive thread 15 are symmetrical with respect to the YZ plane (the plane perpendicular to the X axis).

Next, a cross section of the conductive thread 14 will be described with reference to FIG. In this embodiment, the conductive thread 14 is composed of 34×8=272 monofilaments (single fibers) 141 . That is, the conductive yarn 14 is constructed by twisting together eight multifilaments each composed of 34 monofilaments (single fibers) 141 . As a result, the cross-sectional shape of the conductive thread 14 does not become extremely elongated, but becomes generally circular. The configuration of the conductive thread 15 is basically the same as the configuration of the conductive thread 14 .

Here, the base fabric 110 includes first non-conductive yarns arranged along a first direction and second non-conductive yarns arranged along a second direction orthogonal to the first direction. consists of The first direction is the Y-axis direction and the second direction is the X-axis direction. Here, when the base fabric 110 is a woven fabric, the minimum shape composed of the first non-conductive yarn and the second non-conductive yarn is basically a rectangle. The fiber structure 100 will stretch most when pulled in a direction parallel to the diagonals of this rectangle. In this embodiment, this rectangle is a rectangle that is close to a square, and the ratio of the length of the short side to the length of the long side is close to one.

In this case, the directions in which the fiber structure 100 extends the most are the third direction and the fourth direction. The third direction is an intermediate direction between the first direction and the second direction, and is the V-axis direction shown in FIG. The fourth direction is an intermediate direction between the first direction and the second direction, and is the W-axis direction shown in FIG. Here, when the X-axis, the Y-axis, the V-axis, and the W-axis are on the XY plane perpendicular to the Z-axis direction, the angle formed by the V-axis and the X-axis, the angle formed by the V-axis and the Y-axis, Both the angle formed by the W axis and the X axis and the angle formed by the W axis and the Y axis are approximately 45 degrees. Even if neither the first non-conductive yarn nor the second non-conductive yarn is elastic, the fiber structure 100 stretches to some extent in the third and fourth directions. In addition, when the base fabric 110 is a knitted fabric, it has stretchability derived from the loop structure of the threads forming the knitted fabric.

In this embodiment, conductive yarns are inserted into a base fabric 110 including first non-conductive yarns and second non-conductive yarns, essentially such that the conductive yarns are exposed only on surface 130 . That is, basically, in this embodiment, the conductive thread is inserted so that the back surface 140 is covered with at least one of the first non-conductive thread and the second non-conductive thread. However, whether or not the conductive thread is exposed on the back surface 140 may change depending on whether or not the fiber structure 100 is in a stretched state. For example, depending on the insertion method, the conductive thread may not be exposed on the back surface 140 when the fiber structure 100 is stretched, and the conductive thread may be exposed on the back surface 140 when the fiber structure 100 is not stretched. Therefore, in the present embodiment, both when the fiber structure 100 extends most in the third direction or the fourth direction and when the fiber structure 100 does not extend in any direction, the conductive The conductive thread is inserted so that the thread is not exposed on the back surface 140, and specifically, it is woven.

Here, it is preferable to use a stretchable thread as the first non-conductive thread. When a stretchable yarn is used as the first non-conductive yarn, a force that shrinks the fiber structure 100 in the Y-axis direction acts, so that the first non-conductive yarn and the second non-conductive yarn cause the conductive yarn to move to the back surface. This is because exposure to 140 becomes difficult. It is considered that the conductive yarns are more likely to be exposed on the back surface 140 when the fiber structure 100 is not stretched than when the fiber structure 100 is stretched. Therefore, it is effective to use a stretchable yarn as the first non-conductive yarn to suppress exposure of the conductive yarn to the back surface 140 when the fiber structure 100 is not stretched. Note that when a stretchable yarn is used as the first non-conductive yarn, the elongation rate of the fiber structure 100 in the third direction and the fourth direction is, for example, between 10% and 100%. is preferred.

In addition, the inventors of the present application have noticed that when the thickness of the first non-conductive yarn is too thin, it is difficult to obtain the effect of suppressing the exposure of the conductive yarn to the back surface 140 by the first non-conductive yarn. Then, the inventor of the present application considers the size and cross-sectional shape of the first non-conductive yarn and conductive yarn, and the cross-sectional area of the first non-conductive yarn is 10% or more of the cross-sectional area of the conductive yarn. In this case, the first non-conductive yarn is highly effective in suppressing exposure of the conductive yarn to the back surface 140 . When the conductive yarn or the non-conductive yarn is multifilament, the cross-sectional area and cross-sectional shape are specified by regarding the bundle of filaments as one thread. For example, the sum of the cross-sectional areas of all filaments is considered the cross-sectional area of conductive yarns and non-conductive yarns. Also, for example, the cross-sectional shape of the filament bundle is regarded as the cross-sectional shape of the conductive yarn or the non-conductive yarn.

In addition, the inventors of the present application have noticed that when the thickness of the second non-conductive yarn is too thin, it is difficult to obtain the effect of suppressing the exposure of the conductive yarn to the back surface 140 by the second non-conductive yarn. Then, the inventor of the present application considers the size and cross-sectional shape of the second non-conductive yarn and conductive yarn, and the cross-sectional area of the second non-conductive yarn is 10% or more of the cross-sectional area of the conductive yarn. In this case, the second non-conductive yarn is highly effective in suppressing the exposure of the conductive yarn to the back surface 140 .

In addition, the inventors of the present application focused on the fact that when the first non-conductive yarns are arranged at too wide intervals, it is difficult to obtain the effect of suppressing the exposure of the conductive yarns to the back surface 140 by the first non-conductive yarns. did. Considering the fact that the cross-sectional shape of the first non-conductive yarn is substantially circular, the inventors of the present application believe that the first non-conductive yarn has a radius larger than the cross-sectional radius of the first non-conductive yarn. It has been found that the first non-conductive yarns are highly effective in suppressing the exposure of the conductive yarns to the back surface 140 when they are arranged side by side in the second direction at short intervals.

In addition, the inventors of the present application focused on the fact that when the intervals at which the second non-conductive yarns are arranged are too wide, it is difficult to obtain the effect of suppressing the exposure of the conductive yarns to the back surface 140 by the second non-conductive yarns. did. Considering the fact that the cross-sectional shape of the second non-conductive yarn is substantially circular, the inventors of the present application believe that the second non-conductive yarn has a radius larger than the cross-sectional radius of the second non-conductive yarn. It has been found that the second non-conductive yarn is highly effective in suppressing the exposure of the conductive yarn to the back surface 140 when the yarns are arranged side by side in the first direction at short intervals.

Examples 1-4 are described below. In addition, Example 1 and Example 2 are examples in which a stretchable yarn is used as the first non-conductive yarn. On the other hand, Examples 3 and 4 are examples in which a stretchable yarn is not used as the first non-conductive yarn. Examples 1 and 3 are examples in which the pattern of the conductive layer 120 made of conductive yarn is a checkered pattern. On the other hand, Examples 2 and 4 are examples in which the pattern of the conductive layer 120 made of conductive yarn is a wave pattern. In Examples 1-4, the wale density is 18/inch and the course density is 66/inch.

As shown in FIG. 5, in Examples 2 and 4, when the fiber structure 100 is viewed from above, that is, when the fiber structure 100 is viewed from the positive direction in the Z-axis direction, the pattern of the conductive layer 120 is a wave pattern.

Next, with reference to FIG. 6, the arrangement of the conductive threads when the conductive layer 120 has a wavy pattern will be described. As in the lattice pattern, the conductive threads 14 and 15 are used as the conductive threads. As shown in FIG. It extends diagonally in a straight line in the middle direction between the positive direction in the Y-axis direction and the positive direction in the X-axis direction, extends in a straight line in the positive direction in the Y-axis direction, and extends in the positive direction in the Y-axis direction and in the X direction. It repeats the motion of extending obliquely in a straight line in the direction intermediate to the negative direction in the axial direction. In this manner, the conductive thread 14 forms the corrugated conductive layer 120 by advancing in the positive direction in the Y-axis direction while being displaced in the positive and negative directions in the X-axis direction.

The conductive thread 15 extends linearly in the positive direction in the Y-axis direction, extends obliquely in a straight line in the middle direction between the positive direction in the Y-axis direction and the negative direction in the X-axis direction, and extends in the Y-axis direction. It repeats the motion of extending in a straight line in the positive direction and extending obliquely in a straight line in the middle direction between the positive direction in the Y-axis direction and the positive direction in the X-axis direction. In this way, the conductive thread 15 forms the corrugated conductive layer 120 by advancing in the positive direction in the Y-axis direction while being displaced in the positive and negative directions in the X-axis direction. The conductive thread 14 and the conductive thread 15 are woven at the same time, but the direction of advance in the X-axis direction is opposite. That is, the movement of the conductive thread 14 and the movement of the conductive thread 15 are symmetrical with respect to the YZ plane (the plane perpendicular to the X axis).

(Example 1)
The first embodiment will be described below with reference to FIGS. 7 to 12. FIG. In Example 1, stretchable yarn is used as the first non-conductive yarn, and the pattern of the conductive layer 120 made of the conductive yarn is a lattice pattern. In Example 1, the knitting structure shown in Table 1 below was used. The guide indicates the reed on which the threads are placed. The thread count indicates the number of threads placed in the guide. The tissue indicates how the guide should move. The used fiber indicates the fiber used as the thread.

A non-conductive yarn 10 having no stretchability and no conductivity is arranged in L0. The color of the non-conductive thread 10 is black. A non-conductive thread 11 having no stretchability and no conductivity is arranged in L1. The color of the non-conductive thread 11 is black. A non-conductive thread 12 having stretchability and no conductivity is arranged in L2. The color of the non-conductive thread 12 is black. A non-conductive thread 13 having no stretchability and no conductivity is arranged in L3. A conductive thread 14, which is an insertion thread having no stretchability and conductivity, is arranged in L4. A conductive thread 15, which is an insertion thread having no stretchability and conductivity, is arranged in L5. The non-conductive yarn 10 and the non-conductive yarn 12 are the first non-conductive yarn mentioned above. The non-conductive thread 11 and the non-conductive thread 13 are the second non-conductive thread described above.

Here, the cross-sectional area of the first non-conductive yarn (non-conductive yarn 10, non-conductive yarn 12) is 10% or more of the cross-sectional area of the conductive yarn (conductive yarn 14, conductive yarn 15). The cross-sectional area of the second non-conductive yarns (non-conductive yarn 11, non-conductive yarn 13) is also 10% or more of the cross-sectional area of the conductive yarns (conductive yarn 14, conductive yarn 15). The cross-sectional shape of the first non-conductive yarn (non-conductive yarn 10, non-conductive yarn 12) and the second non-conductive yarn (non-conductive yarn 11, non-conductive yarn 13) is substantially circular. The first non-conductive yarn (non-conductive yarn 10, non-conductive yarn 12) is spaced longer than the radius of the cross section of the first non-conductive yarn (non-conductive yarn 10, non-conductive yarn 12), the second arranged side by side. On the other hand, the second non-conductive yarn (non-conductive yarn 11, non-conductive yarn 13) is arranged at intervals shorter than the radius of the cross section of the second non-conductive yarn (non-conductive yarn 11, non-conductive yarn 13). They are arranged side by side in one direction.

FIG. 7 is a diagram based on an enlarged photograph (magnification: 100 times) of surface 130 . A region 150 is a region of the surface 130 that includes a portion where the conductive thread is exposed. As shown in FIG. 7, in Example 1, the conductive yarn is exposed on the surface 130 of the fiber structure 100 . A detailed description will be given below with reference to FIG.

FIG. 11 shows a cross-sectional view taken along line AA in FIG. FIG. 11 is a diagram based on an enlarged photograph of the cross section (magnification: 100 times). As shown in FIG. 11 , in Example 1, the conductive yarn is not exposed on the rear surface 140 of the fiber structure 100 . A detailed description will be given below with reference to FIG. FIG. 12 is a trace diagram of the cross-sectional view shown in FIG. FIG. 12 shows how two sets of the conductive thread 14 and the conductive thread 15 are arranged.

Also, the conductive layer 120 is composed of at least one of the conductive threads 14 and 15 . As shown in FIG. 12, the exposure of the conductive yarns arranged in the areas indicated by dashed lines 1201 and 1202 to the rear surface 140 is suppressed by the non-conductive yarns arranged in the area indicated by the dashed lines 1102 . In addition, exposure of the conductive threads arranged in the areas indicated by broken lines 1203 and 1204 to the rear surface 140 is suppressed by the non-conductive threads arranged in the area indicated by the broken lines 1103 .

As described above, in Example 1, neither the conductive yarn 14 nor the conductive yarn 15 is visible from the back surface 140 of the fiber structure 100. Therefore, neither the conductive yarn 14 nor the conductive yarn 15 is not exposed from the rear surface 140 of the fiber structure 100. Therefore, when the fiber structure 100 obtained in Example 1 and the fiber structure 200 formed in the same manner as the fiber structure 100 are superimposed to form the fiber structure 1000, the insulation between the two conductive layers is reduced. is maintained.

(Example 2)
A second embodiment will be described below. In Example 2, a stretchable yarn is used as the first non-conductive yarn, and the conductive layer 120 made of the conductive yarn has a wave pattern. In Example 2, the knitting structure shown in Table 2 below was used. Example 2 differs from Example 1 in thread insertion and structure, but the correspondence between the guide and the thread is the same as in Example 1. That is, the non-conductive yarn 10 is arranged in L0, the non-conductive yarn 11 is arranged in L1, the non-conductive yarn 12 is arranged in L2, the non-conductive yarn 13 is arranged in L3, and the conductive yarn is arranged in L4.

Although not shown, in Example 2, as in Example 1, neither the conductive yarn 14 nor the conductive yarn 15 is visible from the back surface 140 of the fiber structure 100. Therefore, the conductive yarn 14 and the conductive yarn 15 and are not exposed from the back surface 140 of the fiber structure 100 . Therefore, when the fiber structure 100 obtained in Example 2 and the fiber structure 200 formed in the same manner as the fiber structure 100 are superimposed to form the fiber structure 1000, the insulation between the two conductive layers is maintained.

(Example 3)

In Example 3, a stretchable yarn is not used as the first non-conductive yarn, and the pattern of the conductive layer 120 made of conductive yarn is a lattice pattern. In Example 3, the knitting structure shown in Table 3 below was used. In Example 3, the guide L5 and the non-conductive thread 12 are not used. That is, the non-conductive yarn 10 is arranged in L0, the non-conductive yarn 11 is arranged in L1, the non-conductive yarn 13 is arranged in L2, the conductive yarn 14 is arranged in L3, and the conductive yarn is arranged in L4. 15 are placed.

The cross-sectional area of the second non-conductive yarns (non-conductive yarn 11, non-conductive yarn 13) is also 10% or more of the cross-sectional area of the conductive yarns (conductive yarn 14, conductive yarn 15). The cross-sectional shape of the first non-conductive yarn (non-conductive yarn 10) and the second non-conductive yarn (non-conductive yarn 11, non-conductive yarn 13) is substantially circular. The first non-conductive threads (non-conductive threads 10) are arranged side by side in the second direction at intervals longer than the radius of the cross section of the first non-conductive threads (non-conductive threads 10). On the other hand, the second non-conductive yarn (non-conductive yarn 11, non-conductive yarn 13) is arranged at intervals shorter than the radius of the cross section of the second non-conductive yarn (non-conductive yarn 11, non-conductive yarn 13). They are arranged side by side in one direction.

FIG. 13 shows an enlarged plan view of the surface 130 of the fiber structure 100 according to Example 3. As shown in FIG. FIG. 13 is a diagram based on an enlarged photograph (magnification: 100 times) of surface 130 . As shown in FIG. 13 , in Example 3, the conductive yarn is exposed on the surface 130 of the fiber structure 100 . A detailed description will be given below with reference to FIG.

14 is a trace diagram of the enlarged plan view shown in FIG. 13. FIG. In FIG. 14, two non-conductive yarns 10 extend in the Y-axis direction while gathering conductive yarn 14 and conductive yarn 15 as a set, and two non-conductive yarns 13 extend in the X-axis direction as a set, and the conductive yarn 14 and conductive thread 15 are shown as a set arranged along the X-axis direction.

FIG. 15 shows an enlarged plan view of the rear surface 140 of the fiber structure 100 according to Example 3. As shown in FIG. FIG. 15 is a diagram based on an enlarged photograph (magnification: 100 times) of the back surface 140 . As shown in FIG. 15, in Example 3, when looking at the back surface 140 of the fiber structure 100, the conductive yarn is visible. However, in Example 3, the conductive yarn is not exposed on the back surface 140 of the fiber structure 100 . A detailed description will be given below with reference to FIG.

16 is a trace diagram of the enlarged plan view shown in FIG. 15. FIG. In FIG. 16, two non-conductive yarns 10 are set and extend in the Y-axis direction while gathering conductive yarn 14 and conductive yarn 15, and two non-conductive yarns 11 are set and extended in the Y-axis direction. 14 and conductive thread 15 are shown as a set arranged along the X-axis direction. As shown in FIG. 16, when looking at the back surface 140 of the fiber structure 100, the non-conductive yarn 10, the non-conductive yarn 11, the conductive yarn 14, and the conductive yarn 15 are visible, and the non-conductive yarn 13 is not visible.

FIG. 17 shows a cross-sectional view taken along line BB in FIG. FIG. 17 is a diagram based on an enlarged photograph of the cross section (magnification: 100 times). As shown in FIG. 17, in Example 3, the conductive yarn is visible when viewed from the back surface 140 of the fiber structure 100, but the conductive yarn is not exposed on the back surface 140 of the fiber structure 100. A detailed description will be given below with reference to FIG. 18 is a trace of the cross-sectional view shown in FIG. 17. FIG. FIG. 18 shows how two sets of the conductive thread 14 and the conductive thread 15 are arranged.

In FIG. 18, dashed lines 1105-1107 indicate regions where the non-conductive yarns that make up the base fabric 110 are arranged, and dashed lines 1205-1208 show regions where the conductive yarns that make up the conductive layer 120 are arranged. . The base fabric 110 is composed of at least one non-conductive yarn among the non-conductive yarns 10-13. Also, the conductive layer 120 is composed of at least one of the conductive threads 14 and 15 . As shown in FIG. 18, the exposure of the conductive yarns located in the areas indicated by dashed lines 1205-1208 to the back surface 140 is apparently suppressed by the non-conductive yarns located in the areas indicated by dashed lines 1105-1107. It looks like it hasn't.

In fact, the conductive yarns are visible when viewed from the back surface 140 of the textile structure 100 . However, the visible portion of the conductive yarn is recessed with respect to the base fabric 110 surrounding this visible portion. For example, the coordinate in the Z-axis direction of the visible portion of the conductive thread arranged in the area indicated by the dashed line 1206 is the lowest coordinate in the Z-axis direction among the base fabrics 110 surrounding this visible portion. It is larger than the coordinate (P0) of a point (not shown) in the Z-axis direction by L1. This L1 is, for example, several millimeters. Similarly, the visible portions of the conductive thread located in the areas indicated by dashed lines 1207 and 1208 are recessed with respect to the base fabric 110 surrounding the visible portions. It should be noted that the conductive thread arranged in the area indicated by dashed line 1205 is not visible from back surface 140 . Therefore, the conductive thread is not exposed on the back surface 140 even though it is visible from the back surface 140 .

As described above, in Example 3, both the conductive yarn 14 and the conductive yarn 15 are visible from the back surface 140 of the fiber structure 100, but both the conductive yarn 14 and the conductive yarn 15 are It is not exposed from the back surface 140 of the fiber structure 100. - 特許庁Therefore, when the fiber structure 100 obtained in Example 3 and the fiber structure 200 formed in the same manner as the fiber structure 100 are superimposed to form the fiber structure 1000, the insulation between the two conductive layers is maintained.

(Example 4)
Example 4 will be described below. In Example 4, non-stretchable yarn is used as the first non-conductive yarn, and the conductive layer 120 made of the conductive yarn has a wave pattern. In Example 4, the knitting structure shown in Table 4 below was used. Example 4 differs from Example 3 in thread insertion and structure, but is the same as Example 3 in terms of correspondence between guides and threads. That is, the non-conductive yarn 10 is arranged in L0, the non-conductive yarn 11 is arranged in L1, the non-conductive yarn 13 is arranged in L2, the conductive yarn 14 is arranged in L3, and the conductive yarn is arranged in L4. 15 are placed. In addition, the cross-sectional area and arrangement interval of the first non-conductive yarn (non-conductive yarn 10), and the cross-sectional area and arrangement interval of the second non-conductive yarn (non-conductive yarn 11, non-conductive yarn 13) is similar to

Although not shown, in Example 4, similar to Example 3, the conductive yarns 14 and 15 are visible from the back surface 140 of the fiber structure 100, but both the conductive yarns 14 and 15 is not exposed from the rear surface 140 of the fiber structure 100. Therefore, when the fiber structure 100 obtained in Example 4 and the fiber structure 200 formed in the same manner as the fiber structure 100 are superimposed to form the fiber structure 1000, the insulation between the two conductive layers is maintained.

Table 5 shows the results of Examples 1 to 4. A resistance value is a resistance value between both ends of a 20 cm×10 cm diagonal. When the pattern of the conductive layer 120 is a lattice pattern (Examples 1 and 3), the resistance value is smaller than when the pattern of the conductive layer 120 is a wave pattern (Examples 2 and 4). Further, when a stretchable thread is used for the base fabric 110 (Examples 1 and 2), the conductive thread is not visible from the back surface 140, and when the stretchable thread is not used for the base fabric 110 (Example 3 and Example 4), the conductive yarn is visible from the back surface 140 . However, the conductive thread is not exposed from the back surface 140 in any of the embodiments. That is, even if two fiber structures 100 formed in any of the embodiments are combined to form the fiber structure 1000, the insulation between the two conductive layers is maintained.

(Embodiment 2)
In Embodiment 1, an example of forming the fiber structure 1000 used for the transmission sheet by stacking two fiber structures 100 with the conductive layer 120 exposed only on the surface 130 has been described. In the present invention, if one fiber structure 100 is used, the fiber structure overlaid on this fiber structure 100 may not be the fiber structure 100 . In this embodiment, a fiber structure 100 having a conductive layer 120 exposed only on the surface 130 and a fiber structure 201 containing a conductor are stacked to form a fiber structure 1001 used for a transmission sheet. .

As shown in FIG. 19, fiber structure 1001 is formed by stacking fiber structure 100 and fiber structure 201 . The fiber structure 201 may, for example, be formed only of conductive threads, or may be formed of conductive threads and non-conductive threads. Fiber structure 201 has a front surface 231 and a back surface 241 . The surface 231 is the surface with smaller coordinates in the Z-axis direction of the two surfaces of the fiber structure 201 . The conductive threads are exposed from the surface 231 . The back surface 241 is the surface with larger coordinates in the Z-axis direction of the two surfaces of the fiber structure 201 . The conductive thread may or may not be exposed from the back surface 241 .

Here, the fiber structure 1001 is formed by fixing the back surface 140 of the fiber structure 100 and the back surface 241 of the fiber structure 201 . The fixing method can be adjusted as appropriate. For example, a fixing method such as bonding with an adhesive, bonding with a double-sided tape, or sewing with a non-conductive thread can be adopted. In the fiber structure 1001, since the conductive yarn is not exposed from the back surface 140 of the fiber structure 100, insulation between the two conductive layers is achieved regardless of whether or not the conductive yarn is exposed from the back surface 241 of the fiber structure 201. is guaranteed.

(Modification)
Although the embodiments of the present invention have been described above, various modifications and applications are possible in carrying out the present invention.

In the present invention, any part of the configurations, functions, and operations described in the above embodiments may be adopted. Further, in addition to the configurations, functions, and operations described above, further configurations, functions, and operations may be employed in the present invention. Moreover, the above-described embodiments can be freely combined as appropriate. Also, the number of components described in the above embodiments can be adjusted as appropriate. Further, it goes without saying that materials, sizes, electrical characteristics, etc. that can be used in the present invention are not limited to those shown in the above embodiments.

Examples 1 to 4 describe examples in which the cross-sectional area of the first non-conductive yarn and the cross-sectional area of the second non-conductive yarn are 10% or more of the cross-sectional area of the conductive yarn. The cross-sectional area of the first non-conductive yarn may be less than 10% of the cross-sectional area of the conductive yarn. Also, the cross-sectional area of the second non-conductive yarn may be less than 10% of the cross-sectional area of the conductive yarn. Moreover, in Examples 1 to 4, examples were described in which the second non-conductive yarns were arranged side by side in the first direction at intervals shorter than the radius of the cross section of the second non-conductive yarns. The second non-conductive yarns may be arranged side by side in the first direction with a spacing greater than the radius of the cross-section of the second non-conductive yarns. In other words, the configuration is not limited to the configurations shown in Examples 1 to 4 as long as the configuration suppresses the exposure of the conductive yarn to the back surface 140 .

Moreover, in Examples 1 to 4, examples were described in which the first non-conductive yarns were arranged side by side in the second direction at intervals longer than the radius of the cross section of the first non-conductive yarns. When the first non-conductive yarns are arranged side by side in the second direction at intervals shorter than the radius of the cross section of the first non-conductive yarns, the effect of further suppressing the exposure of the conductive yarns to the back surface 140 is obtained. I can expect it.

In Embodiment 1, the configuration of the fiber structure 1000 that functions as a transmission sheet has been described. A usage example of the fiber structure 1000 will be described below. The textile structure 1000 can be incorporated into clothing worn by a user (wearer). The fiber structure 1000 is processed into a desired size and shape, for example, and sewn as cloth for clothing. An example in which clothes are used as clothes in which the fiber structure 1000 is incorporated will be described below. 20, 21 and 22 show an example in which six fiber structures 1000 including fiber structures 1000A, 1000B, 1000C, 1000D, 1000E and 1000F are sewn onto clothes. The fiber structures 1000A, 1000B, 1000C, 1000D, 1000E, and 1000F are collectively referred to as the fiber structure 1000 as appropriate.

The fiber structure 1000A is the fiber structure 1000 used as the fabric of clothes from the right chest to the right abdomen. The fiber structure 1000B is the fiber structure 1000 used as the fabric of clothing from the left chest to the left abdomen. The fiber structure 1000C is the fiber structure 1000 used as the fabric of clothes from the right shoulder to the right wrist. The fiber structure 1000D is the fiber structure 1000 used as the fabric of clothing from the left shoulder to the left wrist. The fiber structure 1000E is the fiber structure 1000 used as the cloth for clothing on the right side of the back. The fiber structure 1000F is the fiber structure 1000 used as the cloth for clothing on the left side of the back.

The fiber structure 1000 includes a power supply (not shown), a light emitting element (not shown), a vibration element (not shown), a temperature control component (not shown), a sensor (not shown), a control circuit (not shown), and a control circuit (not shown). not shown). The power supply supplies power to the light emitting element, the vibration element, the sensor, and the control circuit through the fiber structure 1000 . A light-emitting element presents various information to a user by light emission. The light emitting element is, for example, an LED (Light Emitting Diode) or an incandescent lamp. The vibrating element stimulates the user by vibrating. Temperature control components are, for example, Peltier elements, fans, heaters, and movable ventilation holes. A sensor detects various physical quantities. The sensors are, for example, acceleration sensors, angular velocity sensors, and temperature sensors. The control circuit controls the states of the light emitting element, the vibration element, the temperature control part, etc. according to the detection result of the sensor. The control circuit includes, for example, a processor and memory.

How the control circuit performs control can be adjusted as appropriate. For example, the control circuit can cause the light-emitting element to emit light in accordance with the physical condition of the user estimated from the detection result of the sensor. Also, the control circuit can light the light-emitting element in a light-emitting pattern associated with the user's ID. Also, the control circuit can inform the user that some event has occurred by vibrating the vibrating element. For example, the control circuit can vibrate vibration elements provided on each part of the user's body in response to the occurrence of an event while the user is experiencing VR (Virtual Reality). Also, the control circuit can identify the movement of the user from the detection results of the acceleration sensors provided on each part of the user's body.

It should be noted that the light-emitting element is preferably attached to the front side of the clothing. Moreover, it is preferable to attach a sensor (for example, a temperature sensor, a humidity sensor) that detects a physical quantity related to the user's body to the back side of the clothing. The temperature sensor may be a sensor that detects the user's body temperature, or may be a sensor that detects the temperature inside the clothing (the temperature near the user's skin). Also, this humidity sensor is basically a sensor that detects the humidity inside the clothes (humidity in the vicinity of the user's skin). However, the locations where the light emitting elements and sensors are attached are not limited to this example. Further, the fiber structure 1000 may be provided only on the outer material of existing clothing, may be provided only on the lining of the existing clothing, or may be provided on both the outer material and the lining.

For example, sensors that detect physical quantities related to the user's environment (e.g., temperature sensor, humidity sensor) are placed on the front side of the clothes, and sensors that detect physical quantities related to the user's body (e.g., temperature sensors, humidity sensors) are placed on the back side of the clothes. is preferably attached to the The temperature control component is preferably attached to the back side of the garment, the front side of the garment, or through the garment. For example, the control circuit detects a change in the user's environment (ambient temperature change, ambient humidity change), or a change in the user's body condition (body temperature change, temperature change near the skin, humidity change near the skin). ), temperature control components on various parts of the user's body can be activated. Further, the control circuit can identify the movement of the user from the detection results of the acceleration sensors provided on each part of the user's body.

The size and shape of the fiber structure 1000 are appropriately adjusted according to the purpose of use, capacity of production equipment, power and information transmission capacity, and the like. It should be noted that the fiber structure 1000 may be attached to existing clothing by bonding with an adhesive or bonding with a double-sided tape instead of sewing with thread.

Examples of applying the fiber structure to clothes have been described above. Examples of clothes include hats, gloves, socks, supporters, shoes, etc., and it goes without saying that the fiber structure can be applied to these. do not have.
