The fiber product to be the object of the present invention is a product manufactured using a knitted fabric obtained by knitting or knitting a natural fiber, a semi-synthetic fiber, or a synthetic fiber using a thread, and the shape, size, thickness, and the like thereof are not particularly limited.
(electronic functional Member)
Fig. 1 is a partially cut-away plan view of an electronic functional member used in the present embodiment, and fig. 2 is a longitudinal sectional view of line II-II' of fig. 1. The electronic functional member 1 has: a core portion 5 and a sheath portion 20 covering the core portion 5. The core wire portion 5 includes: a first insulated clad metal wire 10 and a second insulated clad metal wire 11 extending along the length direction thereof, and an electronic function portion 12 electrically connected with the first insulated clad metal wire 10 and the second insulated clad metal wire 11, respectively. The knitted fabric 21 is used for the sheath portion 20. In addition, a chip component is used in the electronic function section 12.
As shown in fig. 2, the first insulated and clad metal line 10 is composed of a metal line 10a covered with an insulating layer 10b, and the second insulated and clad metal line 11 is composed of a metal line 11a covered with an insulating layer 11 b. A part of the insulating layer 10b is removed and a joint portion 16 is formed so that the joint portion 16 is in contact with the exposed metal line 10 a. In addition, a part of the insulating layer 11b is removed and a joint portion 17 is formed so that the joint portion 17 is in contact with the exposed metal line 11 a. The electronic function portion 12 has a rectangular shape, and has a pair of external electrodes 12a and 12b as the electronic function portion at both ends. The external electrode 12a is connected to the bonding portion 16, and the external electrode 12b is connected to the bonding portion 17, whereby the electronic function portion 12 is electrically connected to the metal line 10a and the metal line 11 a. In this way, the peripheries of the electrically connected electronic function portion 12 and the metal wires 10a and 11a are covered with the knitted fabric 21. The bonding portions 16 and 17 may be configured as a structure different from the bonding material by plating or the like, but when the insulating layers 10b and 11b are thin, the bonding portions 16 and 17 may be configured by a bonding material such as solder or a conductive adhesive. In the region where the core wire portion 5 is covered with the knitted fabric 21, the core wire portion 5 is sealed from the outside.
Copper wire or nickel wire can be used as the metal wire constituting the core wire portion. Preferably a copper wire. The diameter of the metal wire is not particularly limited as long as it is a size capable of being knitted into a knitted fabric, but is 1 μm or more and 1mm or less, preferably 1 μm or more and 0.5mm or less. The insulating layer is a layer for preventing direct contact between the metal wires, and a urethane resin, an acrylic resin, or a long insulating sheet or tape can be used. In this embodiment, the insulating layer exposes a part of the metal line in order to ensure electrical conduction with the electronic functional portion. Here, the area of a part of the metal line is not particularly limited as long as the part is not the entire surface of the metal line.
The electronic function unit is a member having a function of an active element such as a transistor, a diode, or a peltier element, a passive element such as a resistor, a capacitor, an inductor, or a thermistor, and can be selected from the group consisting of a chip component, a film containing an electronic function substance, a battery, an input element, a display element, a sensor, an antenna, a composite element of these elements, and an integrated circuit.
The passive element may be a chip component, or may be a film containing an electronic functional substance, such as a thick film resistor, a thin film capacitor, or a thin film inductor. The passive element may be an organic material containing an electronic functional substance, a Composite material, or a paste material. The film containing an electronic functional material can be formed by applying a solution containing an element material, for example, a dielectric material, to the surfaces of the plurality of metal lines by a known thick film printing method such as spin coating or screen printing, and then performing a heat treatment. In addition, an electron functional material-containing film patterned by a thin film process can also be used. In this case, for example, a lift-off method, vapor deposition, sputtering, or the like can be used. In the lift-off method, after a Resist (Resist) is applied to the surfaces of a plurality of metal lines and the Resist is patterned by photolithography, a solution containing an element raw material is applied, and thereafter, the Resist is lifted off to leave only a pattern of a target thin film. Specific examples of the electronic function unit include an NTC thermistor, a PTC thermistor, and a peltier element. If these elements are used in clothing using an electronic functional member, for example, if an NTC thermistor is used, the temperature of the clothing can be measured; if the PTC thermistor is used, the clothing can be heated; if the peltier element is used, the cloth can be cooled.
The electronic function unit includes a plurality of terminal units for transmitting and receiving signals to and from an external device. Specific examples of the terminal portion include an external electrode, a terminal, an electrode pad, and the like. For example, when the two terminal portions are two terminals, one terminal can be connected to one metal wire, and the other terminal can be connected to the other metal wire.
The sheath portion may include a member of a knitted fabric covering the core wire portion, and may be formed of one or more covering portions laminated on the outer periphery of the core wire portion. The knitted fabric can be used for any of the coatings, but it is preferably used for the first coating which is located on the core portion side and at least a part of which is in contact with the core portion. In the present embodiment, an example is shown in which the sheath portion is constituted only by the first covering portion formed of a knitted fabric.
The developed view of the knitted fabric 21 is shown in fig. 3. The knitted fabric 21 can form a tubular knitted fabric covering the periphery of the core portion 5 by weft knitting the knitting yarn. Weft knitting is preferable because the mesh can be made finer than warp knitting. In addition, since the weft knitting is performed such that the mesh is knitted so as to include the longitudinal core wire portion by the knitting yarn, the core wire portion can be strongly fastened by the knitting yarn of the sheath portion, and therefore the sheath portion can be brought into close contact with the core wire portion.
In the present embodiment, the filament containing the thermoplastic resin is contained in at least a part of the knitted fabric of the electronic functional member, and/or the filament containing the thermoplastic resin is knitted with the electronic functional member. The thermoplastic resin present in the vicinity of the electronic functional member can be melted and solidified by heating the region including the electronic functional member. Thus, the region including the electronic functional member can be formed in accordance with the shape of the target product, and therefore the electronic functional member can be easily mounted also on the target product having a complicated shape.
In the case where a yarn (hereinafter, also referred to as a thermoplastic fiber yarn) containing the thermoplastic resin is contained in the electronic functional member in at least a part of the knitted fabric of the electronic functional member, for example, the yarn can be produced by using the thermoplastic fiber yarn in at least a part of the knitted fabric. Examples of the thermoplastic resin include a polyurethane resin, a polyethylene resin, a polyester resin, a polyamide resin, and a polypropylene resin. Preferably, thermoplastic synthetic fiber yarns made of thermoplastic resins such as polyethylene resins, polyester resins, polyamide resins, and polypropylene resins can be used. The thickness of the knitted yarn is preferably 33 decitex (dtex) or more and 250 dtex or less. This is because if the yarn thickness is less than 33 dtex, the covering of the core portion by the knitted fabric is insufficient, and if the yarn thickness is more than 250 dtex, the knitting yarn is too thick and the knitting by the knitting machine is difficult. In addition, a plurality of thermoplastic filaments made of thermoplastic resins having different melting points, a composite filament made of a thermoplastic filament, a filament having no thermoplasticity, or the like can be used.
In addition, even when the thermoplastic fiber yarn is knitted with the electronic functional member, the same thermoplastic fiber yarn as described above can be used for knitting.
The number of meshes (needle holes) in the same course (course) in the knitted fabric is not particularly limited, but is preferably two or more and eight or less. Since the diameter of the tubular knitted fabric can be reduced, the adhesion of the knitted fabric to the core wire portion can be further improved.
The number of meshes per natural length of 1cm of the same wale (wale) in the knitted fabric is not particularly limited, but is preferably 6 or more and 14 or less. Here, the natural length refers to a length in a state where no tension or the like is applied, that is, a state where the table is naturally placed directly thereon. When the number of meshes per natural length of 1cm of the same wale of the knitted fabric is 6 or more, the coating rate of the core wire portion by the knitted fabric can be increased. Further, if the number of meshes per natural length of 1cm of the same wale of the knitted fabric is 14 or less, it is possible to suppress the occurrence of a defect of overlapping of meshes of the knitted fabric (tuck defect) due to an excessively small mesh.
In addition, when the thermoplastic fiber yarn is used as the knitting yarn of the knitted fabric, as described above, the thermoplastic fiber yarn existing in the vicinity of the electronic functional member is melted and solidified, and the region including the electronic functional member can be formed in accordance with the shape of the target product, and the following effects are obtained. That is, the covering rate and the adhesion of the core wire portion with the knitted fabric obtained by heating, melting and cooling the thermoplastic fiber filaments included in the knitted fabric and then solidifying the same are improved, whereby the electronic functional member and the metal wire can be protected from moisture derived from sweat during washing. In addition, the adhesion between the core wire portion and the sheath portion can be further improved by heating while applying pressure. When a conjugate fiber composed of a plurality of thermoplastic filaments having different melting points is used as the knitted yarn, the knitted fabric can be heated to a temperature higher than the melting point of the thermoplastic filament having a lower melting point and lower than the melting point of the thermoplastic filament having a higher melting point, and only the thermoplastic filament having a lower melting point can be melted while the high melting point thermoplastic filament remains in the knitted fabric, thereby improving the durability.
The electronic functional member can be manufactured by the following method, for example. Namely, comprising: a step of forming a core wire portion including at least two metal wires, an insulating layer covering the at least two metal wires in such a manner that a part of the at least two metal wires is exposed, and an electronic function portion electrically connected to the at least two metal wires, respectively; and forming a sheath portion covering the core portion, wherein the step of forming the sheath portion includes at least a step of covering the core portion by knitting a knitted fabric around the core portion by weft knitting.
The step of forming the core wire portion may further include: a step of forming a conductive pattern on the plurality of metal wires, and a step of attaching at least one electronic function portion to the plurality of metal wires. For example, in the case of using two metal wires, as shown in fig. 2, a part of the insulating layer on the surface of each metal wire is removed to expose the surface of the metal wire, thereby forming a joint portion providing a conductive pattern. The number of the conductive patterns can be selected according to the number of the input/output terminals of the electronic function portion and the number of the electronic function portion. The shape of the conductive pattern can be various shapes such as a line, a rectangle, a circle, and a dot. When the electronic function portion is attached to the plurality of wires, it is preferable to attach the electronic function portion to the plurality of wires parallel to each other in a direction perpendicular to a longitudinal direction of the plurality of wires from the viewpoint of stretchability and durability. In addition, when the plurality of electronic functional portions are mounted along the longitudinal direction of the metal wire, a plurality of conductive patterns can be formed at predetermined intervals along the longitudinal direction of the metal wire. The conductive pattern can be formed by a printing method or an electroplating method using a conductive paste.
The step of covering the core portion can form a tubular knitted fabric covering the periphery of the core portion by weft-knitting the knitting yarn using a circular knitting machine. For the circular knitting machine, a known circular knitting machine described in, for example, jp 60-193993 a can be used.
(method of manufacturing woven/knitted Fabric)
The knitted fabric used in the present embodiment can be manufactured by supplying an electronic functional member to a knitting machine to manufacture a knitted fabric, or by supplying an electronic functional member to a knitting machine to manufacture a knitted product. That is, the method for manufacturing a knitted fabric used in the present embodiment includes: a step of manufacturing a knitted fabric in which the electronic functional member is knitted in at least a part thereof, in which the electronic functional member including a thread including the thermoplastic resin is knitted in at least a part of the knitted fabric, and/or the electronic functional member is knitted with a thread including the thermoplastic resin in at least a part of a region of the knitted fabric.
Hereinafter, the case of the woven and knitted fabric will be described. An electronic functional member including a Yarn (thermoplastic fiber) containing a thermoplastic resin in a knitting Yarn of a knitted fabric is fed to a knitting machine alone (knitting method 1), or an electronic functional member not containing a thermoplastic fiber and one or more natural fibers, semisynthetic fibers, synthetic fibers, and the like containing at least a thermoplastic fiber are combined in a knitting Yarn of a knitted fabric to feed the Yarn to the knitting machine (knitting method 2), or an electronic functional member containing a thermoplastic fiber and one or more natural fibers, semisynthetic fibers, and synthetic fibers containing at least a thermoplastic fiber are combined in a knitting Yarn of a knitted fabric to feed the Yarn to the knitting machine (knitting method 3). Examples of methods for combining an electronic functional member with a common synthetic fiber yarn include: a method of knitting an electronic functional member and a normal synthetic fiber yarn by feeding the yarns from different yarn paths of the face yarn, a method of knitting the same yarn by feeding the yarns from the yarn paths of the same face yarn and aligning the yarns. The knitted fabric can be knitted by plain knitting, rib knitting (rib stich), double-sided knitting, purl stich (purl stich), loop knitting (pile stich), or the like. In addition, the electronic functional member and the normal synthetic fiber yarn can be fed from the yarn path of the face yarn and the yarn path of the back yarn, respectively, and then the yarn adding knitting (plating knitting) can be used. In addition, from the viewpoint of economy, the electronic functional member can be incorporated only in a specific and necessary portion by intarsia knitting (double-sided knitting).
The knitting method 1 is a method of feeding an electronic functional member including thermoplastic fiber yarn in knitting yarn of a knitted fabric to a knitting machine alone, but it is also possible to use dope yarn and/or back yarn as needed. In this case, the filler yarn and the back yarn can use natural fiber yarn, semi-synthetic fiber yarn, or synthetic fiber yarn that does not contain thermoplastic fiber yarn. This prevents the molten thermoplastic fiber filaments from melting and falling off during the heat treatment.
Next, knitting method 2 will be explained. In the weaving method 2, filler wires and/or back wires are used. Fig. 4A is a schematic plan view showing an example of the structure of the woven fabric, and fig. 4B is a schematic longitudinal sectional view of the woven fabric. The woven fabric 70A is woven from an electronic functional member 71, back yarns 72, and filler yarns 73. The type of yarn used for the knitted fabric constituting the sheath portion of the electronic functional member 71 is not particularly limited, and for example, a natural yarn, a semi-synthetic yarn, or a synthetic yarn, which does not include a thermoplastic yarn, can be used. In addition, the filler yarn and the back yarn use natural fiber yarn, semi-synthetic fiber yarn or synthetic fiber yarn containing at least thermoplastic fiber yarn. In the case where one of the filler yarn and the back yarn includes a thermoplastic fiber yarn, the other yarn may be omitted, or as described later, a non-melting fiber yarn, for example, a regenerated fiber yarn such as rayon or a thermoplastic fiber yarn that does not melt at a temperature at which the one yarn melts may be used. In addition, both the filler yarn and the back yarn may not contain the thermoplastic fiber yarn.
In fig. 4A and 4B, thermoplastic fiber filaments are used as the filler filaments 73. The back yarn 72 has a function of preventing the melted yarn 73 from melting and dropping when the woven fabric is subjected to heat treatment, and holding the melted yarn 73. The filler wire 73 is melted and solidified by heat treatment to increase rigidity. The region including the electronic functional member in the woven fabric can be melted and solidified to be molded into a predetermined shape by performing heat treatment in cooperation with a predetermined mold so as to match the shape of the target product.
Fig. 4A and 4B show an example in which the filling yarn 73 is knitted on the entire surface of the knitted fabric 70A, but the filling yarn 73 may be knitted only in a predetermined region. In fig. 4A and 4B, an example is shown in which thermoplastic filaments are used only for the filler filaments 73, but thermoplastic filaments that melt at or below the melting point of the filler filaments 73 may be used for the back filaments 72. A planar resin region can be formed to cover the periphery of the electronic functional member.
Fig. 5A is a schematic plan view showing another example of the structure of the woven fabric, and fig. 5B is a schematic longitudinal cross-sectional view of the woven fabric. The knitted fabric 70B is knitted by a ground stitch (moss stitch) using the face yarn 74, the back yarn 72, and the filler yarn 73 made of a thermoplastic fiber yarn. An electronic functional member is used in the face wire 74. The knitted fabric 70B can be knitted in a pattern by knitting the filler yarn 73 in a bead mesh manner. For example, in the woven fabric 70B, the region where the electronic functional portion is to be arranged is formed by weaving the filler yarn 73 and the back yarn 72, and the other portion is formed by weaving the face yarn 74 and the back yarn 72. The face yarn 74 and the filling yarn 73 appear to be broken at the end 74a and the end 73a, but are connected in the lateral direction by the technique of float knitting that floats on the back surface of the knitted fabric in the actual knitting structure. In other words, the portion where the face yarn 74 is knitted so as to straddle the filler yarn 73 and the portion where the filler yarn 73 is knitted so as to straddle the face yarn 74 are knitted in a bead-mesh arrangement.
Further, as shown in fig. 5B, when the knitted fabric 70B is knitted as a mesh with beads and the filler yarn 73 is formed into a mesh shape and subjected to heat treatment, the region including the electronic functional portion can be made more difficult to break and difficult to break. Further, by using the transparent filler yarn 73 not containing a matte material (matting material) without using the back yarn 72, or by using the transparent thermoplastic fiber yarn not containing a matte material also in the back yarn 72, the region containing the electronic function portion can be made transparent.
Fig. 6A is a schematic plan view showing another example of the structure of the woven fabric, and fig. 6B is a schematic vertical cross-sectional view of the woven fabric. The knitted fabric 70C is knitted by cut-weave (cut-weave) using the face yarn 74, the back yarn 72, and the filling yarn 73 made of thermoplastic fiber yarn. An electronic functional member is used in the face wire 74. The knitted fabric 70C can be cut-pile knitted, and the filler yarn 73 can be knitted in a pattern. For example, in the woven fabric 70C, the regions where the electronic functional portions are to be arranged are formed by weaving the filler yarns 73 and the back yarns 72, and the other portions are formed by weaving the face yarns 74 and the back yarns 72. In addition, different from the bead-ground eyelet knitting shown in fig. 5A, knitting yarns are cut at a portion 75 where the face yarn 74 and the filling yarn 73 overlap.
Next, knitting method 3 will be explained. In the knitting method 3, the knitting yarn of the knitted fabric is used which contains the electronic functional member of the thermoplastic fiber yarn and the dope yarn and/or the back yarn, and the dope yarn and the back yarn are used which contain at least the natural fiber yarn, the semi-synthetic fiber yarn or the synthetic fiber yarn of the thermoplastic fiber yarn. When the thermoplastic fiber yarn is included in one of the filler yarn and the back yarn, the other yarn may be omitted, or as described later, a non-melting fiber yarn, for example, a regenerated fiber yarn such as rayon, or a thermoplastic fiber yarn that does not melt at a temperature at which the one yarn melts may be used. Both the filler yarn and the back yarn may contain thermoplastic fiber yarn.
In addition, the braid can include at least one power supply portion electrically connected with the electronic function portion. The electrical connection between the electronic function unit and the power supply unit can be performed by the metal wire constituting the core portion, and therefore, it is not necessary to newly provide a lead wire to connect the electronic function unit and the power supply unit. This allows the electronic function unit and the power supply unit to be easily connected. The external device electrically connectable to the electronic function unit is not limited to the power supply unit, and may be a signal generator, a transmission device, a reception device, a detection device, a measurement device, a display device, an input device, or the like.
According to the present embodiment, a fiber product having an electric and electronic function that can be applied to an object product having a complicated shape can be provided. In addition, since the electronic function member to which the electric and electronic functions are applied can electrically connect the external device such as the power supply portion and the electronic function portion by the metal wire constituting the core portion, the connection between the external device and the electronic function portion can be easily performed.
The fiber product according to the present embodiment is a fiber product obtained by melting and solidifying the thermoplastic resin contained in the fiber product according to embodiment 1, and is different from the fiber product according to embodiment 1 in that the solidified thermoplastic resin is contained in at least a part of the knitted fabric of the electronic functional member and/or at least a part of the periphery of the electronic functional member.
In the fiber product according to the present embodiment, the solidified thermoplastic resin is contained in at least a part of the knitted fabric of the electronic functional member and/or at least a part of the periphery of the electronic functional member, and the thermoplastic resin is melted and solidified, whereby the region containing the electronic functional member can be formed in conformity with the shape of the target product. Further, the electronic functional member can be integrated with the knitted fabric by welding the cured thermoplastic resin to other knitted yarns. Thus, even if the knitted fabric is stretched or contracted, the electronic functional member is not broken and is not peeled off from the knitted fabric. Further, since the rigidity of the region in which the electronic functional portion is arranged can be increased to achieve high strength and low elongation, the deformation of the region can be suppressed to improve the durability of the electronic functional portion.
The following describes a method for producing the same. The method for producing a fiber product according to the present embodiment includes: a step of manufacturing a knitted fabric in which the electronic functional member is knitted in at least a part thereof, in which the electronic functional member including a thread including the thermoplastic resin is knitted in at least a part of the knitted fabric, and/or the electronic functional member is knitted with a thread including the thermoplastic resin in at least a part of a region of the knitted fabric; and a step of melting and solidifying the filaments containing the thermoplastic resin, which are woven into the woven fabric.
In the present manufacturing method, when the electronic functional member is knitted with a yarn (thermoplastic yarn) containing a thermoplastic resin, the thermoplastic yarn may be a thermoplastic yarn having a melting point lower than that of the other knitted yarn, or a thermoplastic yarn having the same melting point as that of the other knitted yarn. When a thermoplastic fiber yarn having a melting point lower than that of the other knitted yarn is used, it is preferable to use a thermoplastic fiber yarn having a melting point lower by 30 degrees or more, preferably lower by 50 ℃ or more than that of the other knitted yarn.
The heating temperature for melting and solidifying the thermoplastic fiber filaments can be appropriately set according to the melting point of the thermoplastic fiber filaments used, but it is necessary not to exceed the upper limit of the heat-resistant temperature of the electronic functional portion included in the electronic functional member.
In the case of fig. 4A, as an example of the combination of the knitted yarns, the sheath portion of the electronic functional member is knitted into a knitted fabric using a natural fiber yarn or a synthetic fiber yarn having a higher melting point (a synthetic fiber yarn having a higher melting point than the thermoplastic fiber yarn), and the back yarn using a fiber having a higher melting point (a fiber yarn having a higher melting point than the thermoplastic fiber yarn), such as nylon or polyurethane. After knitting, only the region where the electronic functional part is arranged or the entire surface of the knitted fabric is heated under pressure as necessary to melt and solidify only the thermoplastic fiber yarn having the lowest melting point.
Examples of the knitting yarn used for the knitting fabric and combinations of the thermoplastic fiber yarn to be melted and other knitting yarns are shown in table 1. Here, the non-melt fiber in table 1 means a fiber other than the thermoplastic fiber to be melted and used for the sheath portion and the back yarn of the electronic functional member, and the melt fiber means a thermoplastic fiber to be melted.
TABLE 1
The combination of the molten fibers and the non-molten fibers is not limited to the range shown in table 1, and the melting point of the non-molten fibers may be 30 degrees or higher than the melting point of the molten fibers.
This embodiment has the same configuration as the fiber product of embodiment 1, except that a sheath portion is used as the electronic functional member, the sheath portion including a first covering portion that is formed of a knitted fabric and is in contact with the core portion, and a second covering portion that covers at least a part of the first covering portion and presses the first covering portion toward the core portion side.
Fig. 7 is a partially cut-away plan view of the electronic functional member according to the present embodiment, and fig. 8 is a vertical sectional view taken along line VIII-VIII' of fig. 7. Hereinafter, the description of the portions common to embodiment 1 will be omitted, and only the different portions will be described.
The electronic functional member 2 includes a core wire portion 5 and a sheath portion 20 covering the core wire portion 5. The sheath portion 20 includes: a first covering portion 22 formed of a knitted fabric and located on the core portion 5 side, and a second covering portion 23 wound around the first covering portion 22. The second coating portion 23 can press the first coating portion 22 toward the core wire portion 5 to bring the first coating portion 22 into close contact with the core wire portion 5.
The second coating portion may use a long member. The elongate members include natural fibers such as cotton, hemp and wool, semisynthetic fibers such as cellulose, synthetic fibers such as nylon, acrylic, polyester and polyurethane, and composite fibers, tapes and ropes obtained by combining a plurality of fiber materials. The first covering portion can be brought into close contact with the core portion by using the elongated member without damaging the core portion. In addition, when the synthetic fiber yarn containing the thermoplastic resin is used in the first covering portion, the synthetic fiber yarn containing the thermoplastic resin may be used in the second covering portion. After the coating with the second coating portion, the synthetic fiber yarn is heated and melted, and the adhesion of the first coating portion to the core wire portion can be further improved after cooling.
In addition, the following examples may be applied as a combination of the first coating portion and the second coating portion. For example, when a synthetic fiber yarn containing a thermoplastic resin is used in the first covering portion, a yarn composed of the non-melting fiber described above (hereinafter referred to as a non-melting fiber yarn) can be used in the second covering portion. In addition, a non-melting fiber yarn may be used in the first covering portion, and a synthetic fiber yarn containing a thermoplastic resin may be used in the second covering portion. In this case, too, the adhesion of the first coating portion to the core wire portion can be improved.
The electronic functional member used in this embodiment can be manufactured by a manufacturing method including a step of winding an elongated member in a spiral shape around the first covering portion after the first covering portion is formed. The second coating portion can be formed by winding the electronic functional member with a thread bobbin (bobbin) while rotating the thread bobbin (bobbin) and continuously unwinding the cord wound around the thread bobbin, by using a known sheath yarn winding device described in, for example, japanese patent application laid-open No. 63-282304, while moving the electronic functional member on which the first coating portion is formed upward or downward. Further, the winding interval of the second coating portion in the longitudinal direction of the electronic functional member can be adjusted as necessary. The winding interval can be reduced (or the number of windings can be increased) to further improve the adhesion of the first covering portion to the core portion. In addition, the wire diameter of the second coating portion can be increased to reduce the winding interval, thereby further improving the adhesion of the first coating portion to the core portion.
According to this embodiment, in addition to the effect of embodiment 1, by providing the second coating portion, the adhesion of the first coating portion to the core wire portion can be further improved, and the durability of the electronic functional member can be further improved.
In the present embodiment, although an example in which the second coating portion is provided is shown, a coating portion may be further provided as necessary. For example, the second coating portion may be spirally wound in the longitudinal direction of the electronic functional member, and the second coating portion may be provided with a third coating portion wound in the opposite direction to the second coating portion so as to intersect the second coating portion. By providing the third coating portion, the adhesion of the first coating portion to the core wire portion can be further improved.
Further, an aligning yarn made of synthetic fiber yarn containing thermoplastic resin may be provided between the core yarn portion and the first covering portion. In this case, the adhesion of the first covering portion to the core wire portion can be improved. In this case, as a combination of the first coating portion and the second coating portion, there can be mentioned: a case where a synthetic fiber yarn containing a thermoplastic resin is used for both the first covering part and the second covering part; in the case where non-melting filaments are used for both the first coating part and the second coating part; in the case where a synthetic fiber yarn containing a thermoplastic resin is used for one of the first covering part and the second covering part, and a non-melting fiber yarn is used for the other.
The fiber product according to the present embodiment has the same configuration as the fiber product of embodiment 1, except that an electronic functional member including a film of an electronic functional substance is used as an electronic functional section instead of a chip component.
Fig. 9 is a partially cut-away plan view of the electronic functional member according to the present embodiment, and fig. 10 is a longitudinal cross-sectional view taken along line X-X' of fig. 9. Hereinafter, the description of the portions common to embodiment 1 will be omitted, and only the different portions will be described.
The electronic functional member 3 has: a core wire part 6 and a sheath part 20 covering the core wire part 6. The core portion 6 includes a first insulating clad metal wire 10, a second insulating clad metal wire 11, and an electronic function portion 13 formed of an electronic function substance-containing film arranged so as to be electrically conductive with the first insulating clad metal wire 10 and the second insulating clad metal wire 11, respectively.
As described above, the film containing an electronic functional substance can be formed by applying a solution containing an element material, for example, a dielectric material, to the surfaces of the plurality of metal wires by a known printing method such as spin coating and performing heat treatment. In addition, a patterned thin film can also be used. Here, the electronic functional substance includes a dielectric material, a conductive material, a magnetic material, a piezoelectric material, a semiconductor material, a pyroelectric material, and the like.
According to the present embodiment, in addition to the effect of embodiment 1, the following fiber product can be provided: since the size and thickness of the electronic functional portion attached to the metal wire can be flexibly changed by using the film containing the electronic functional substance, the fiber product of the electronic functional member can be optimally designed according to the application.
The fiber product according to the present embodiment has the same configuration as the fiber product of embodiment 1, except that a long insulating member is used as an insulating layer for covering the metal wires, and an electronic functional member formed as a film containing an electronic functional substance covering the outer peripheries of the plurality of metal wires in a band shape is used as the electronic functional portion instead of the chip component.
Fig. 11 is a partially cut-away plan view of the electronic functional member according to the present embodiment, and fig. 12 is a vertical cross-sectional view taken along line XII-XII' of fig. 11. The electronic functional member 4 includes a core portion 7 and a sheath portion 20 covering the core portion 7. The core wire portion 7 includes: metal wires 10a and 11a extending in the longitudinal direction with an insulating member 15 interposed therebetween; and an electronic function material-containing film 14 formed to cover the outer peripheries of the metal wires 10a, 11a in a band shape and arranged to be electrically conductive with the metal wires 10a, 11 a. The knitted fabric 21 is used for the sheath portion 20.
Examples of the insulating member of the electronic functional member used in the present embodiment include a long insulating sheet interposed between the metal wires, an insulating tape attached along the longitudinal direction of the metal wires, and an insulating layer formed along the longitudinal direction of the metal wires. The insulating layer can be formed using urethane resin, acrylic resin, or the like.
As described above, the film containing an electronic functional material can be formed by applying a solution containing an element material, for example, a dielectric material, to the surfaces of the plurality of metal lines by a known printing method such as spin coating and performing a heat treatment. In addition, a patterned thin film element can also be used.
According to the present embodiment, in addition to the effect of embodiment 1, the following fiber product can be provided: the size and thickness of the electronic functional part attached to the metal wire can be flexibly changed by using the film containing the electronic functional substance, and therefore, the fiber product of the electronic functional member can be optimally designed according to the application.
Although the electronic functional units are described as an example in embodiments 1 to 5, the electronic functional member used in the fiber product of the present invention may include a plurality of electronic functional units. For example, it is also possible to have: a first electronic function portion arranged to be electrically conductive with each of the metal wires of the first wiring portion composed of at least two metal wires; and a second electronic function portion arranged to be electrically conductive with each of the metal wires of a second wiring portion composed of at least two metal wires different from the first wiring portion. Similarly, the third wiring portion and the third electronic function portion, the fourth wiring portion and the fourth electronic function portion, the fifth wiring portion and the fifth electronic function portion, and the like may be provided. The first electronic function unit may be different from the other electronic function units, or all the electronic function units may be the same. For example, a temperature sensor element (e.g., an NTC thermistor) can be used in the first electronic functional part, and a heat generating element (e.g., a PTC thermistor) can be used in the second electronic functional part.
Fig. 13 is a schematic view showing an example of the structure of the electronic functional member having a plurality of electronic functional portions, and the sheath portion is omitted. The core portion 30 includes metal wires 31, 32, 33, 34, 35, and 36 each covered with an insulating layer. Two wires 31, 32 constitute a first wiring portion 37, the other two wires 33, 34 constitute a second wiring portion 38, and the other two wires 35, 36 constitute a third wiring portion 39. The first electronic function portion 41 is joined to the joining portion 31a where a part of the metal wire 31 is exposed and the joining portion 32a where a part of the metal wire 32 is exposed. A second electronic function portion 42 is joined to the joint portion 33a where a part of the metal wire 33 is exposed and the joint portion 34a where a part of the metal wire 34 is exposed. Further, a third electronic function portion 43 is joined to the joining portion 35a where a part of the metal wire 35 is exposed and the joining portion 36a where a part of the metal wire 36 is exposed. Fig. 13 shows an example in which six wires are arranged in parallel, but the first to third electronic functional portions may be bundled so as not to contact each other.
In addition, the electronic functional member used in the fiber product of the present invention may have a circuit formed by connecting a plurality of electronic functional portions to each other by at least two wires. This form is described in detail in embodiment 6 below.
In the electronic functional member used in the fiber product according to the present embodiment, the core wire portion includes a plurality of electronic functional portions, and the plurality of electronic functional portions are connected to each other by at least two wires to form a circuit (hereinafter, this circuit is also referred to as a built-in circuit). Fig. 14 is a block diagram showing an example of the configuration of the built-in circuit. The circuit 60 includes a plurality of circuit element portions constituting a circuit, and the circuit element portions correspond to electronic function portions. The circuit 60 includes, as a circuit element portion: the passive element section 61, the active element section 62, a control section 63 for controlling the operations of the passive element section 61 and the active element section 62, a communication section 64 for performing output and input of a communication signal with the outside, a power supply section 65 for supplying power to each section, an a/D converter section 66 for performing a/D conversion on a data signal from the passive element section 61 and outputting the data signal to the control section 63, a D/a converter section 67 for performing D/a conversion on a control signal from the control section 63 and supplying the control signal to the active element section 62, a transmitting/receiving antenna section 68 for performing wireless transmission/reception with the outside, and a wireless charging section 69 for receiving a radio wave for electric power from the outside and outputting power generated by the radio wave for electric power to the power supply section 65. The external device includes a display unit 70 for displaying predetermined image information from the control unit 63.
The passive element section 61 can use, for example, a sensor as a passive element. In this case, the passive element portion is also referred to as a sensor portion. Examples of the sensor include a temperature sensor, an infrared sensor, a humidity sensor, an acoustic sensor, an optical sensor, a magnetic sensor, a pressure sensor, an acceleration sensor, and a position sensor. As the active element, the active element section 62 can use, for example, a heating element or a vibrator. The combination of the passive element and the active element can be variously selected according to the use of the electronic functional member. For example, the temperature adjustment function can be provided to the electronic functional member by using a temperature sensor as the passive element and a heating element as the active element. For example, a capacitor or a secondary battery can be used as the power supply unit 65.
The interconnection of the plurality of electronic functional units can be performed, for example, as follows: a plurality of electronic function parts are arranged along the length direction of the two metal wires and electrically connected with the metal wires.
The electronic functional member used in this embodiment can also be formed into a woven or knitted product by using the same method as that described in embodiment 1. That is, a knitted fabric can be produced by supplying an electronic functional member having a built-in circuit to a knitting machine and knitting the member as a normal yarn.
According to this embodiment, in addition to the effect of embodiment 1, it is possible to provide a fiber product in which electronic functional components are further miniaturized by using a circuit instead of a plurality of components such as chips.
In the present embodiment, the passive element portion and the circuit element portion other than the active element portion are not incorporated in the electronic functional component, and an external device is used instead. In this case, although the external device is held by the woven fabric, the passive element portion and the circuit element portion other than the active element portion can be electrically connected to the external device by the metal wire constituting the core portion as described in embodiment 1.
The circuit element portion shown in fig. 14 is an example, and various circuit element portions can be used according to the application.
While the embodiments of the present invention have been described above, these are merely examples, and it will be apparent to those skilled in the art that various modifications can be made within the scope of the present invention. For example, although embodiment 3 shows an example in which a knitted yarn is spirally wound around the first covering portion as the second covering portion, the second covering portion may be formed using a knitted fabric or may be formed using a plated yarn knitting (plating knitting).
