Clothing

The present invention relates to a garment composed of a stretch knitted fabric in which a body cloth covers the body surface.

Patent Document 1 proposes a clothing with a strain sensor capable of capturing a wearer's movement as an electrical signal. The clothing with strain sensor is a fabric with a strain sensor having a stretchable fabric body and a strain sensor attached to the fabric body and capable of following the stretch of the fabric body, and is electrically connected to the strain sensor.

JP 2014-25180 A

However, the stretch performance of the fabric with a strain sensor described in Patent Document 1 depends on the substrate made of synthetic resin, rubber, nonwoven fabric, metal, etc., and does not match the stretch performance of the fabric body. There is a problem that it is difficult to accurately detect the stretched state of the clothes that changes depending on the posture of the person.

Also, when the area of the strain sensor placed on the clothes is increased, there is a problem that the air permeability is hindered by the substrate, and there is a problem that it cannot be worn on a daily basis.

An object of the present invention is to provide a garment that can be worn on a daily basis in view of the above-described problems and that can accurately detect the stretched state of the body cloth resulting from a change in the posture of the wearer.

In order to achieve the above-mentioned object, the first characteristic configuration of the garment according to the present invention is a garment composed of a stretchable fabric in which the body fabric covers the body surface as described in claim 1 of the claims. The posture detection fabric for converting the change in the stretched state of the body fabric into the change in the electrical property is knitted or joined to the body fabric integrally with the body fabric, and the electrical property detected by the posture detection fabric The configuration is such that the posture of the wearer can be detected based on the change.

Due to the change in the electrical characteristics of the posture detection fabric, the stretch knitted fabric for posture detection that is knitted or joined to the body fabric integrally with the stretchable fabric covering the body surface expands and contracts as the body fabric stretches, The posture of the wearer is detected.

In the second feature configuration, as described in claim 2, in addition to the first feature configuration described above, the posture detection fabric is disposed at least in a measurement target portion of the wearer, and the body fabric is expanded and contracted. It is in the point which contains the 1st electroconductive stretch fabric from which electrical resistance changes in correlation with a state.

The first conductive stretchable fabric, which is the posture detection fabric arranged at the measurement target site of the wearer, stretches with the expansion and contraction of the body fabric, and the resistance which is the electrical characteristic of the posture detection fabric in correlation with the stretched state of the body fabric Therefore, the stretched state of the body cloth can be accurately detected as the resistance change of the posture detecting cloth.

In the third feature configuration, as described in claim 3, in addition to the second feature configuration described above, the posture detection fabric is electrically connected to the first conductive stretch fabric, The second conductive stretchable fabric includes a second conductive stretchable fabric having a substantially constant electrical resistance regardless of the stretched state of the body fabric.

There is a possibility that the expansion and contraction of the body cloth cannot be detected satisfactorily by the first conductive stretch fabric only with the structure in which the first conductive stretch fabric is arranged on the measurement target portion of the wearer. This is because the stretch properties of the body fabric change in the region where the first conductive stretch fabric is disposed and in the periphery thereof. For example, when the body cloth is stretched at the measurement target site, there is no problem if the first conductive stretch fabric is stretched integrally with the body cloth. It is assumed that the first conductive stretch fabric is hindered from being stretched excessively.

Even in such a case, by electrically connecting the second conductive stretchable fabric to the first conductive stretchable fabric, excessive stretch on the body fabric side is prevented at the peripheral edge of the first conductive stretchable fabric. In rare cases, the first conductive stretchable fabric can be expanded and contracted in response to the expansion and contraction of the body fabric corresponding to the posture change of the wearer, and the stretched state of the body fabric can be accurately detected. In addition, since the second conductive stretch fabric can function as a signal transmission medium for transmitting the resistance change of the first conductive stretch fabric, it is possible to secure the degree of freedom of electrode arrangement for detecting the resistance change. Will be able to.

In the fourth feature configuration, as described in claim 4, in addition to the first feature configuration described above, the posture detection fabric is left from the vicinity of the right shoulder ridge of the wearer through the right shoulder blade. The right belt-like fabric placed in the region reaching the vicinity of the twelfth rib, and the portion extending from the vicinity of the left shoulder ridge of the wearer to the vicinity of the right twelfth rib through the left scapula A left belt-like cloth, and the right belt-like cloth and the left belt-like cloth are arranged so as to intersect at the lower center of the left and right shoulder blades.

The posture of the wearer's upper body can be detected if it is provided on the body fabric so that the right belt fabric and the left belt fabric that make up the posture detection fabric intersect at the back. become able to. At this time, the right belt-like fabric is arranged in a region from the vicinity of the wearer's right shoulder to the vicinity of the left twelfth rib through the right shoulder blade, and the left belt-like fabric of the wearer's left shoulder When placed in the region from the vicinity through the left scapula to the vicinity of the right twelfth rib, each belt-like cloth is positioned by the shoulder ridge and the twelfth rib, and when the body cloth expands and contracts, the posture detection cloth is It is possible to avoid the deviation from the measurement target part.

In the fifth feature configuration, as described in claim 5, in addition to the fourth feature configuration described above, a plurality of the right belt-like fabrics are arranged in parallel so as to sandwich the right shoulder ridge, A plurality of the left belt-like fabrics are arranged in parallel so as to sandwich the left shoulder ridge.

By arranging each belt-like fabric so as to sandwich the shoulder ridge, each belt-like fabric is not gripped by the shoulder ridge and shifted, and redundant detection is performed by a plurality of posture detection fabrics. The detection accuracy can be improved by obtaining

In addition to the fourth or fifth characteristic configuration described above, the sixth characteristic configuration includes at least left and right shoulder ridges of the right belt-like fabric and the left belt-like fabric. Up to the intersection position, it is composed of a first conductive stretch fabric whose electrical resistance changes in correlation with the stretch state of the body fabric, and the other portions are electrically connected to the first conductive stretch fabric, Regardless of the stretched state of the body cloth, the second embodiment is composed of the second conductive stretchable cloth having a substantially constant electrical resistance.

By configuring the first conductive stretch fabric whose electrical resistance changes in correlation with the stretched state of the body cloth from the left and right shoulder ridges to the crossing position, the influence of the stretch of the body fabric in other areas is affected. Since it is eliminated, the electrical resistance can be measured accurately. In addition, since the second conductive stretch fabric can function as a signal transmission medium that transmits the resistance change of the first conductive stretch fabric, the degree of freedom of electrode arrangement for detecting the resistance change is ensured. Will be able to.

In addition to the first characteristic configuration described above, the seventh characteristic configuration includes the right shoulder blade and the left shoulder blade of the wearer in addition to the first characteristic configuration described above. It includes a horizontal belt-like fabric arranged so as to pass through the left and right shoulder blades or the surrounding area.

The horizontal belt-like fabric detects the stretched state of the skin between the left and right scapulas, and makes it possible to accurately grasp whether the back is curled or the chest is stretched.

In addition to the first characteristic configuration described above, the seventh characteristic configuration includes the right shoulder blade and the left shoulder blade of the wearer in addition to the first characteristic configuration described above. It is in the point including the horizontal belt-like cloth arranged so that it may pass the up-and-down direction lower part of the right and left scapula.

配置 By arranging the horizontal belt-like fabric so as to pass below the scapula in the vertical direction, the stretched state of the skin between the left and right scapula can be detected very well.

In the ninth feature configuration, in addition to the seventh or eighth feature configuration described above, the horizontal belt-like fabric has an electrical resistance that correlates with the stretched state of the body fabric. A second conductive material composed of a first conductive stretch fabric that changes, is electrically connected to an end of the first conductive stretch fabric, and has a substantially constant electrical resistance regardless of the stretch state of the body fabric. The elastic stretch fabric is arranged so as to extend from the left and right shoulders to the chest side.

By electrically connecting the second conductive stretch fabric to the first conductive stretch fabric, the extra stretch on the body fabric side is prevented at the peripheral edge of the first conductive stretch fabric, and the posture of the wearer The first conductive stretchable fabric can be stretched corresponding to the expansion and contraction of the body fabric corresponding to the change, and the stretched state of the body fabric can be accurately detected. In addition, if the second conductive stretch fabric can function as a signal transmission medium that transmits the resistance change of the first conductive stretch fabric and is arranged to extend from the left and right shoulders to the chest side, An arrangement of electrodes for detecting resistance change is arranged on the chest side, and a circuit block for detecting resistance can be operated on the chest side.

In the tenth characteristic configuration, as described in claim 10, in addition to any of the second, sixth, or ninth characteristic configuration described above, the first conductive stretchable fabric is arranged in the course direction. It is composed of a knitted fabric knitted with conductive yarns formed with loops and elastic yarns that are inserted in the course direction and contact each loop in a contracted state and each loop can be separated in an extended state.

When the conductive yarn loops come into contact with each other due to the contraction force of the elastic yarn inserted in the course direction, the electrical resistance at both ends of the first conductive stretchable fabric decreases, and the body fabric stretches against the contraction force of the elastic yarn. The loops of the conductive yarn are separated from each other, and the electrical resistance at both ends of the first conductive stretchable fabric is increased.

According to the eleventh characteristic configuration, as described in claim 11, in addition to any of the third, sixth, or ninth characteristic configuration described above, the second conductive stretchable fabric is looped in the course direction. Is formed by a knitted fabric in which the elastic yarn is heat-sealed to the conductive yarn by heat setting.

Since the elastic yarn is heat-sealed to the conductive yarn by heat setting, the contact state of the loop of the conductive yarn hardly changes even in the stretched state or the contracted state. The value hardly changes.

As described above, according to the present invention, it is possible to provide a garment that can be worn on a daily basis and that can accurately detect the stretched state of the body cloth caused by a change in the posture of the wearer. .

It is a rear view.

Hereinafter, an upper body garment that is an example of the garment according to the present invention will be described with reference to the drawings.
As shown in FIGS. 1 (a), (b), and (c), the upper body garment 100 according to the present invention is a distortion of the posture of the upper body of the wearer, for example, whether or not the back is a stooped back. Etc. are clothes 100 that can be detected on a daily basis.

The clothing 100 includes a front body 2, a back body 3, and a sleeve 4 made of a stretchable body fabric 1 in two directions, and is configured to be in close contact with the surface of the wearer's body. Therefore, when the skin surface expands or contracts in accordance with the change in the posture of the wearer, the body fabric 1 similarly expands and contracts along the skin surface.

In order to detect the degree of expansion / contraction of the body cloth 1 at this time, a posture detection cloth 5 that converts a change in the expansion / contraction state of the body cloth 1 into a change in electrical characteristics is knitted or joined to the body cloth 1 together with the body cloth 1. ing. As a joining mode, there is a mode in which the posture detection fabric 5 is bonded to the body fabric 1 or a mode in which the force detection fabric 5 is sewn to the body fabric 1.

The posture of the wearer can be grasped based on the change in the electrical characteristics detected by the posture detection fabric 5 that expands and contracts as the body fabric 1 expands and contracts.

The posture detection fabric 5 is disposed at least on the measurement target portion of the wearer, and the first conductive stretch fabric 6 and the first conductive stretch fabric 6 change in electrical resistance in correlation with the stretched state of the body fabric 1. And the second conductive stretchable fabric 7 having a substantially constant electrical resistance regardless of the stretched state of the body fabric 1.

More specifically, the posture detection fabric 5 includes a right belt-shaped fabric 5A disposed in a region from the vicinity of the wearer's right shoulder peak 20 to the vicinity of the left twelfth rib through the right shoulder blade and the wearer. The left belt-like fabric 5B and the left belt-like fabric 5B are arranged in a region from the vicinity of the left shoulder ridge 30 through the left shoulder blade to the vicinity of the right twelfth rib. The left and right shoulder blades are arranged so as to intersect at the lower center P0.

The right belt-like fabric 5A starts from the upper right chest P1 and passes through the vicinity of the right shoulder ridge 20 and passes through the right scapula, the central lower part P0 of the scapula, the vicinity of the left twelfth rib P2, and the left abdomen. And arranged in the lower umbilicus P3.

The left belt-like fabric 5B starts from the left upper chest P4 and passes through the vicinity of the left shoulder ridge 30 and passes through the left scapula, the central lower part P0 of the scapula, the right portion of the twelfth rib P5, and the left abdomen. The lower umbilicus P3 is electrically connected to the right belt-like fabric 5A.

Between the right and left

shoulder ridges

20 and 30 and the intersection position P0 of the right belt-like fabric 5A and the left belt-like fabric 5B, first electrical conductivity whose electrical resistance changes in correlation with the stretched state of the body fabric 1 The first conductive stretchable fabric 6 is electrically connected to other portions, that is, between the crossing position P0 and the lower umbilicum P3 and between the left and

right shoulder ridges

20 and 30 to the start points P1 and P4. The second conductive stretchable fabric 7 has a substantially constant electric resistance regardless of the stretched state of the body fabric.

The first conductive stretch fabric 6 may be configured from the left and

right shoulder ridges

20 and 30 to the lower back through the intersection position P0. The 1st electroconductive elastic fabric 6 should just be arrange | positioned in the area | region which covers all or one part of measurement object site | parts.

The first conductive stretch fabric 6 and the second conductive stretch fabric 7 are both bonded or sewn and fixed to the body fabric, and the first conductive stretch fabric 6 and the second conductive stretch fabric 7 The joints are arranged so that the edges are slightly overlapped, and the two are electrically connected by bonding with a conductive adhesive or by sewing and fixing with conductive fibers.

The right belt-like fabric 5A is arranged in a region from the vicinity of the wearer's right shoulder peak 20 through the right shoulder blade to the vicinity of the left twelfth rib, and the left belt-like fabric 5B is placed on the wearer's left shoulder cap. When placed in the region from the vicinity of 30 through the left scapula to the vicinity of the right twelfth rib, the belt-

like fabrics

5A and 5B are respectively positioned by the protrusions of the

shoulder ridges

20 and 30 and the protrusion of the twelfth rib. Due to the anchor effect, it is possible to avoid the posture detection fabric 5 from being displaced from the measurement target site when the body fabric 1 expands or contracts with the change in the posture of the wearer.

The right belt-like fabric 5A is arranged in parallel so as to sandwich the right shoulder ridge 20 and the left belt-like fabric 5B is arranged in parallel so as to sandwich the left shoulder ridge 30.

The pair of belt-like fabrics 5A are arranged so as to sandwich the shoulder ridge 20, and the pair of belt-like fabrics 5B are arranged so as to sandwich the shoulder ridge 30, so that each of the belt-

like fabrics

5A, 5B is gripped by the

shoulder ridges

20, 30. Therefore, the body cloth 1 does not deviate from the skin surface, and the change in electrical characteristics caused by the posture change is redundantly detected by the plurality of posture detection cloths 5, so that the detection accuracy can be obtained by, for example, obtaining an average value. Can be increased.

Since the left and

right shoulder ridges

20, 30 to the intersection position P0 are composed of the first conductive stretch fabric 6 whose electrical resistance changes in correlation with the stretch state of the stretch fabric, the stretch fabric stretches in other areas. The influence by doing will be excluded, and an accurate electrical resistance measurement accompanying a change in the posture of the wearer can be performed.

In addition, there is a possibility that the expansion / contraction of the body cloth cannot be detected satisfactorily by the first conductive stretchable fabric 6 only by the structure in which the first conductive stretchable fabric 6 is arranged on the measurement target portion of the wearer. This is because the stretch properties of the body fabric 1 change in the region where the first conductive stretch fabric 6 is disposed and in the periphery thereof. For example, there is no problem if the first conductive stretch fabric 6 is stretched integrally with the body fabric 1 when the body fabric 1 is stretched at the measurement target portion, but the peripheral portion of the first conductive stretch fabric 6 is In this case, it is assumed that the body cloth 1 side extends excessively and the first conductive stretch cloth 6 is prevented from extending.

Even in such a case, the second conductive stretchable fabric 7 is electrically connected to the first conductive stretchable fabric 6, so that the extra portion of the first conductive stretchable fabric 6 on the side of the body fabric 1 is removed. So that the first conductive stretchable fabric 6 can be stretched in response to the expansion and contraction of the body fabric 1 corresponding to the change in the posture of the wearer, so that the stretched state of the body fabric 1 can be accurately detected. Become. In addition, since the second conductive stretch fabric 7 can function as a signal transmission medium for transmitting the resistance change of the first conductive stretch fabric 6, the degree of freedom of electrode placement for detecting the resistance change is ensured. Will be able to.

As shown in FIG. 2A, a change in resistance value is detected by attaching the signal processing unit SP with the start points P1 and P4 of the right belt-like fabric 5A and the left belt-like fabric 5B as a pair of electrodes. Become. The signal processing unit SP includes, for example, a constant current source and a voltage detection unit, and includes a resistance detection circuit that performs calculations based on Ohm's law, and a constant voltage source and current detection unit, and performs calculations based on Ohm's law. A resistance detection circuit and a wireless transmitter that transmits the calculation result to the outside can be provided.

In addition, one of metal snap buttons S that are fixed by engagement of the concave and convex portions is attached to the starting points P1 and P4 of the right belt-like fabric 5A and the left belt-like fabric 5B that serve as electrodes, and the other is attached to the signal processing unit SP. By mounting, the signal processing unit SP can be configured to be detachable while being electrically connectable to the starting points P1 and P4 serving as electrodes.

In this embodiment, since the right belt-like fabric 5A and the left belt-like fabric 5B are connected by the lower umbilicus P3, a change in series resistance of the pair of left and right first conductive stretch fabrics 6 can be detected. If the lower end portions of the right belt-like fabric 5A and the left belt-like fabric 5B are not electrically connected to each other at the lower umbilicum P3 and are separated from each other so as to be electrically insulated from each other, Each resistance change can be detected at the start point P4 and the end point of the belt-like cloth 5B.

4 and 5 show the knitting structure of the first conductive stretch fabric 6. The first conductive stretch fabric 6 is configured by inserting an elastic yarn 11 in a course direction by an inlay into a flat knitted fabric knitted with a conductive yarn 10. One course of elastic yarn 11 is inserted for each course of the conductive yarn 10, and the elastic yarn 11 is entangled with the loop of the conductive yarn 10 along the conductive yarn 10.

“Conductive yarn” refers to a bare material with metal components exposed on the yarn surface. In addition, the “elastic yarn” is a one that maintains a contracted state when no tensile force is applied (non-elongation = normal state), and freely expands according to the tensile force when a tensile force is applied, and When the tensile force is released and the load is restored when no load is applied, the material is restored (contracted) from the stretched state to the original contracted state.

As the conductive yarn 10, a resin fiber, natural fiber, or metal wire is used as a core, and a metal component is deposited on the core by wet or dry coating, plating, vacuum film formation, or other appropriate deposition methods. It is preferable to use a metal deposition wire (plated wire). Although a monofilament can be used for the core, a multifilament or a spun yarn is preferable to the monofilament. Furthermore, it is also possible to use fibers having elasticity such as polyurethane fibers. As the covering portion, a wooly processed yarn, a covering yarn such as SCY or DCY, or a bulky processed yarn such as a fluffed yarn is more preferable.

Examples of metal components to be deposited on the core include pure metals such as aluminum, nickel, copper, titanium, magnesium, tin, zinc, iron, silver, gold, platinum, vanadium, molybdenum, tungsten, cobalt, alloys thereof, stainless steel Brass, etc. can be used.

As the elastic yarn 11, polyurethane or rubber-based elastomer material may be used alone, or covering yarn using polyurethane or rubber-based elastomer material for the “core” and nylon or polyester for the “cover” is used. can do. By employing such a covering yarn, functions such as hydrophilicity, water repellency, corrosion resistance / corrosion resistance, and coloring can be imparted. It is also useful for improving touch and controlling elongation. It should be noted that a thread containing a conductive material can be used as the elastic thread 11.

Since the elastic yarn 11 is inserted in the course direction with respect to the flat knitted fabric made of the conductive yarn 10, the elastic yarn 11 acts to tighten the flat knitted fabric made of the conductive yarn 10 in the course direction. Thereby, when the body cloth is not extended, the contact state between the loops of the conductive yarns 10 adjacent in the course direction is maintained by the tightening force of the elastic yarn 11 (see FIG. 4).

Each loop of the conductive yarn 10 is deformed into a contracted shape in the course direction, and this deformed shape is maintained. Since the conductive yarn 10 is a conductive bare material, the greater the number of contact points by the loop, and the greater the contact area by being compressed in the course direction, the more the number of conductive contacts, that is, conductive The area is large, the energization path is shortened, and the electrical resistance between two locations separated in the course direction is reduced.

When the body fabric is stretched, the loops of the conductive yarn 10 come apart against the tightening force of the elastic yarn 11. The separation behavior of the loop of the conductive yarn 10 at this time is not that all the loops are separated all at once, but the contact pressure is gradually decreased in proportion to the degree of elongation of the knitted fabric, but the contact state is still maintained ( A case where the contact area is reduced compared to the case of non-extension), a case where contact is released and the gap is gradually widened, or a case where the contact state is maintained when not extended are mixed (FIG. 5). reference).

Therefore, as the elongation starts from the non-elongation and the degree of elongation increases, the conduction area decreases, the energization path becomes longer, and the electrical resistance tends to gradually increase. Naturally, when the stretching force by the body cloth 2 is released, the elastic yarn 11 contracts in the course direction by the tightening force in the course direction and restores the non-stretched state, so that the electrical resistance increases as the conduction area increases. Becomes smaller.

4 and 5, an example in which a flat knitted fabric is knitted with the conductive yarn 10 has been described. However, a ground structure may be constituted by a rubber knitted fabric (milling knitting), and the elastic yarn 11 may be inserted in the course direction by an inlay. .

That is, the first conductive stretchable fabric 6 includes a conductive yarn 10 in which a loop is formed in the course direction, and an elastic yarn 11 that is inserted in the course direction so that the loops come into contact with each other in the contracted state and can be separated in the extended state. It is made up of knitted fabrics.

Further, the second conductive stretchable fabric 7 is knitted with conductive yarns having a loop formed in the course direction and elastic yarns inserted in the course direction, and the elastic yarns are knitted into the conductive yarns by heat setting. It is composed of heat-sealed knitted fabric.

That is, the first conductive stretch fabric 6 is composed of substantially the same knitting structure, low melting point polyurethane is used as the elastic yarn 11, and the conductive yarn 10 thicker than the conductive yarn 10 used in the first conductive stretch fabric 6 is formed. It is used.

Since the elastic yarn 11 is heat-sealed to the knitted portion of the conductive yarn 10 by heat setting, the elastic yarn 11 basically does not exert a contracting force in the course direction, and is in a slightly stretched state. Even in the contracted state, the contact state of the loop of the conductive yarn 10 hardly changes, and therefore the resistance value hardly changes due to expansion and contraction.

The first conductive stretch fabric 6 and the second conductive stretch fabric 7 are formed in a strip shape so that the longitudinal direction is along the course direction.

As shown in FIGS. 6 (a) and 6 (b), the first conductive stretchable fabric 6 is SCY with the elastic yarn 11 as the core and the conductive yarn 10 coated in a single layer or the double coated DCY. It is also possible to use a fabric knitted with the covering yarn 14.

As shown in FIG. 6C, when the fabric is stretched, the elastic yarn 11 itself is stretched to widen the gap between the wound conductive yarns 10 and the contact points of the conductive yarns between adjacent courses are reduced. As a result, the resistance value changes.

FIG. 6D illustrates a plain knitted fabric using such covering yarn. Either SCY or DCY may be used as the covering yarn, but DCY is more preferable because there is an intersection between the conductive yarns, and conduction can be secured, the covering density is easily increased, and the effect of lowering the initial resistance value is obtained. The draft rate of the elastic yarn and the twist number of the conductive yarn may be about the same as the covering yarn usually used for skin wear (for example, the draft rate is about 1.0 to 5.0 times and the twist number is about 50 to 2000 T / m). .

As in this example, the posture detection fabric 5 can be knitted integrally with the body fabric 1, and only the region of the body fabric 1 where the posture detection fabric 5 is to be arranged is knitted integrally with the body fabric 1. It is also possible. Further, as an aspect of knitting integrally with the body cloth 1, it is possible to sew the covering thread described above after knitting the body cloth into the body cloth so as to function as the posture detection cloth 5.

Natural fibers such as cotton are preferably used as the raw yarn for knitting the body fabric 1. In addition to natural fibers, regenerated cellulose fibers such as cupra and viscose rayon, synthetic fibers such as polyester, and the like can be used.

As the fabric 1, a weft knitted fabric such as milling knitting or smooth knitting, and further a tentacle knitting, or a warp knitting fabric such as a Russell knitting can be suitably used. When a weft knitted fabric is used for the body fabric 1, it is preferable that the course direction is along the width of the body and the wale direction is along the length.

The fabric 1 is a knitted fabric in which heat-deformable elastic yarns and other yarns are knitted by plating, and the heat-deformable elastic yarns are thermally deformed by heat-set processing, and the edges are cut. It is more preferable to use a knitted fabric that has been subjected to a release treatment.

If the knitted fabric subjected to such unwinding processing is adopted, the fibers will not be unwound from the end that has been cut off even after repeated washing, and the appearance will not deteriorate. Further, for example, since the conventional anti-breaking process such as folding the end portion and sewing is not necessary, there is no inconvenience due to deterioration of the touch due to the thickness of the end portion due to the conventional anti-unlocking process, Skin-friendly clothing can be provided.

As shown in FIG. 7, the plating knitting is also called splicing knitting, and an existing knitting method can be adopted. For example, it is particularly preferable to use a knitting method in which a plurality of yarns are fed from different yarn feeders to knitting needles because the arrangement of the yarns in each knitting loop is stably determined. Therefore, the plating knitted fabric knitted by feeding the heat-deformable elastic yarn 12 and the other yarn 13 to the knitting needles from different yarn feeders is the heat-deformable elastic yarn 12 and the others in each knitting loop. Since the arrangement with the yarn 13 is stable, the heat-deformable elastic yarn can be adjacent to all the loops, and if the heat-deformable elastic yarn is thermally deformed by heat setting or the like, the entire knitted fabric It will be possible to realize the unlocking function reliably in the loop.

Specifically, a low-melting-point polyurethane elastic yarn is selected as the heat-deformable elastic yarn 12, a mixed yarn of cotton yarn and rayon is selected as the other yarn 13, and a knitted fabric knitted by milling or smooth knitting is heat set. Thus, the low-melting point polyurethane elastic yarn is melted and fused to each other, thereby realizing the release function.

In addition to using a heat-fusible elastic yarn such as a low-melting-point polyurethane elastic yarn as the heat-deformable elastic yarn, it is also possible to use a polyurethane urea elastic fiber. Due to heat treatment such as heat set processing, the polyurethane urea elastic fibers are compressed and deformed at the contact points between the polyurethane urea elastic fibers or between the polyurethane urea elastic fibers and the partner yarn, and the polyurethane urea elastic fibers are bonded to each other or against the polyurethane urea elastic fibers. Since the yarns are fixed, the polyurethane urea elastic fibers and the partner yarns are not easily removed from the knitted fabric, and a knitted fabric in which curling and unwinding are suppressed can be obtained. In other words, the heat-deformable elastic yarn is not limited thereto as long as it has a characteristic of being melted or compressed and deformed by heat treatment.

If such a knitted fabric is used, the front body, the back body and the sleeve can be joined with an adhesive, and the posture detection fabric 5 mentioned above is also joined to the body fabric with an adhesive. Will be able to.

Examples of the thermoplastic resin used as the adhesive include polyurethane hot melt resin, polyester hot melt resin, polyamide hot melt resin, EVA hot melt resin, polyolefin hot melt resin, styrene elastomer resin, and moisture curable urethane. System hot melt resin, reactive hot melt resin and the like. Among them, the reactive hot melt resin is particularly preferable because it has high adhesive strength and can be bonded in a short time.

FIG. 8 shows resistance value characteristics of the first conductive stretch fabric 6 and the second conductive stretch fabric 7. For reference, FIG. 8 also shows the characteristics of a conductive stretch fabric that is knitted using copper wires as conductive yarns and 155 dtex polyurethane fibers as elastic yarns.

The first conductive stretch fabric 6 is composed of a knitted fabric that is knitted using only 155 dtex polyurethane fiber as the core yarn and milled with only the conductive yarn made of DCY by double-covering the core yarn with the plating yarn 33 dtex.

The second conductive stretch fabric 7 uses a 155 dtex polyurethane fiber as the core yarn, a covering yarn obtained by DCYing the core yarn with 231 dtex (77 dtex × 3) as the conductive yarn, and a low melting point of 110 dtex as the elastic yarn. After knitting using polyurethane fibers, the low melting point polyurethane fibers are fused to the intersecting portions of the conductive yarns by heat setting.

The first conductive stretch fabric 6 has a linear relationship between the stretch rate and resistivity of the fabric, but the second conductive stretch fabric 7 has a substantially constant resistivity regardless of the stretch rate of the fabric.

As shown in FIGS. 2 (a), (b), and (c), signal processing units SP are attached to both ends of the posture detection fabric 5 via snap buttons S that serve as electrodes, so that the posture of the wearer is in an upright posture. The amount of change in skin elongation and resistance was measured when changing from a stoop to a dorsal posture. Reference signs A to H indicate the measurement range of the elongation of the skin along the posture detection fabric 5. Reference symbols A, B, and H are portions corresponding to the predecessor, and reference symbols C to G are portions corresponding to the rear portion.

As shown in FIG. 3, when changing to a stooped posture based on an upright posture, the skin stretches in the back and the skin contracts in the front, and the degree of the change can be substantially correlated with the detected resistance change. found. In addition, in FIG. 3, “hand” is the data when the left and right arms are placed along the left and right body sides, and “crossing” is the data when changing to the stooped posture with the left and right arms crossed in front. It is.

In the embodiment described above, the present invention has been described by taking the clothing for the upper body of the short sleeve as an example, but it may be configured as a long sleeve. In the above-described embodiment, the example in which the cut-off cut-off fabric is used as the body fabric has been described.
