Description

  The present invention relates to clothing such as legwear.

  BACKGROUND ART Conventionally, various techniques for adjusting the temperature of clothing worn on a body have been proposed. For example, Patent Literature 1 describes a heated sock that heats a conductive region when a current is applied from a power source. The heated sock can warm the region by applying an electric current. Patent Literature 2 describes a sock made of a fiber material in which a polyurethane elastic fiber containing platinum containing at least alumina and silica is mixed as a metal oxide. When the temperature of the metal oxide falls within a temperature range of about 30 ° C., infrared rays are radiated from the socks, so that the heat retaining effect of the socks can be enhanced.

  However, in the techniques described in Patent Documents 1 and 2, although the sock can be warmed or kept warm, when the temperature of the sock itself increases, heat may be released from the heated portion. Can not. For this reason, there is a problem that, for example, when a person wearing socks exercises or the like, the temperature of a part of the socks whose temperature has increased cannot be reduced.

[Embodiment 1]
Embodiment 1 of the present invention will be described below with reference to FIGS. In the present embodiment, the leg wear worn on the foot 50 (body) will be described as an example. However, the present invention is not limited to the leg wear and can be applied to clothing worn directly on the body. In the following, the legwear 100 is described as being formed of a knit, but the legwear 100 is not limited to a knit and can be formed as a woven fabric.

  The legwear 100 can transfer heat from a high-temperature part to a low-temperature part of the body using the thermal conductivity of a metal wire. In other words, the legwear 100 has an effect of cooling a warm part in the legwear 100 and warming a cold part. In addition, the legwear 100 can transfer heat from the body to the metal wire or from the metal wire to the body using the heat transfer property of the metal wire.

  The metal wire is preferably a coated metal wire. For example, when an enameled metal wire is used, washing resistance can be increased.

(Structure of legwear)
FIG. 1A is a right side view of the legwear 100 according to the first embodiment of the present invention, and FIG. 1B is a plan view of FIG. 1A as viewed from the sole side. The legwear 100 (clothing) includes a main body 1 and a heat transfer / heat transfer region 2 as shown in FIGS.

  The main body 1 forms a portion of the legwear 100 other than the heat conduction / heat transfer region 2. The main body 1 is made of a predetermined yarn using a suitable yarn such as a yarn obtained by blending one or two or more natural fibers such as cotton, wool, acrylic, or the like, or a yarn obtained by mixing or adhering ceramic with these yarns. Are knitted in sizes and shapes.

  The main body 1 includes a foot portion 20 and a leg portion 30. The foot part 20 covers the foot part from the ankle (ankle part) to the toe of the foot inserted into the legwear 100. The foot portion 20 has a toe portion 21 that covers the toe of the foot to be inserted. One end of the toe 21 is knitted in a bag shape. The leg portion 30 covers the lower leg from the ankle among the legs inserted into the legwear 100. The leg 30 has an opening 31 at one end, and the other end is knitted adjacent to the foot 20. The legwear 100 may be, for example, a high sock in which the leg portion 30 extends below the knee, or a legless sock in which the leg portion 30 is short.

(Heat conduction / heat transfer area)
The heat conduction / heat transfer region 2 is a band-shaped region provided on the main body 1 and including the metal thread 13. The heat conduction / heat transfer region 2 is provided so as to conduct heat from a high temperature part (a high temperature part) to a low temperature part (a low temperature part) of the body.

  Specifically, the heat conduction / heat transfer region 2 is knitted by the composite yarn 10 having the metal yarn 13 as the core yarn 11. Details of the composite yarn 10 will be described later. Further, as shown in FIGS. 1A and 1B, the heat conduction / heat transfer region 2 is formed in an annular shape from the sole of the foot to the instep of the foot at a position close to the toe portion 21. Have been. In other words, the heat conduction / heat transfer region 2 is arranged from at least the sole region of the foot, which is a region visible when the foot is viewed from the sole, to the instep region of the foot, which is a region other than the sole region of the foot. ing. Note that the sole region of the foot is a region corresponding to a portion where the temperature of the foot is high in the legwear 100, and the instep region is a region corresponding to a portion where the temperature of the foot is low in the legwear 100. is there. In addition, the region that can be seen when the foot is viewed from the back side is, for example, the region illustrated in FIG.

  Since the heat conduction / heat transfer region 2 includes the metal thread 13, the heat conductivity / heat transfer property is higher than that of the main body 1. In addition, the metal thread 13 in the heat conduction / heat transfer region 2 contacts the portion where the foot temperature is relatively high from the portion where the foot temperature is relatively high in the heat conduction / heat transfer region 2. It is arranged without interruption until the point where it does. Therefore, in the heat conduction / heat transfer region 2, the heat of the foot is transferred to the metal thread 13 at a position where the foot contacts a relatively high temperature portion. In addition, heat conduction is performed from a portion of the metal thread 13 where the foot temperature is relatively high to a portion where the foot temperature is relatively low and a portion where the foot temperature is relatively low. At the location, the heat of the metal thread 13 is transferred to the foot. In other words, the heat conduction / heat transfer region 2 can transfer heat from a portion where the temperature of the foot is high to a portion where the temperature is low due to its heat conductivity / heat transferability. That is, the legwear 100 can transfer the heat generated from the foot (body) to the portion having a low temperature via the heat conduction / heat transfer region 2. For this reason, the legwear 100 lowers the temperature of the sole of the foot by moving the heated sole of the foot to the instep (instep) side after performing exercise such as running or soccer, for example. be able to. When kicking out the ground, the bottom of the foot is more susceptible to weight at the base of the toes (ball and toe ground) than the other parts, causing frictional heat with the bottom of the shoe Cheap. Therefore, by arranging the heat conduction / heat transfer region at the base of the toe, the heat on the sole side of the foot can be efficiently released.

  In addition, the width (thickness) of the band of the heat conduction / heat transfer region 2 can be set arbitrarily, and the larger the width of the band, the higher the heat conductivity and heat conductivity of the heat conduction / heat transfer region 2. .

(Composition of composite yarn)
FIG. 2A is a diagram showing the composite yarn 10 of the legwear 100 in a partially broken view, and FIG. 2B is a longitudinal sectional view of the composite yarn 10. FIG. 3 is a photograph showing an example of a specific structure of the composite yarn 10 shown in FIG. As shown in FIGS. 2A and 2B, the composite yarn 10 includes a core yarn 11 and a cover 12 (covered fiber).

  The core yarn 11 is a metal yarn bundle in which a number of metal yarns 13 are bundled. As the metal thread 13, for example, copper, aluminum, silver, or the like can be used. In consideration of thermal conductivity, heat transfer, corrosiveness, and the like, it is desirable to use a copper wire as the metal thread 13. The core thread 11 may be constituted by one metal thread 13 or may be constituted by a plurality of metal threads 13. The thickness of the metal thread 13 (copper wire) is desirably 120 μm or less. As shown in FIG. 3, a plurality of metal threads, for example, when four copper wires are used as the core thread 11, the thickness is 60 μm. Desirably.

  The periphery of the core yarn 11 is covered by a cover 12. The cover 12 is a synthetic fiber, and is desirably a fiber having a high thermal conductivity such as polyethylene. In addition, polyester may be used for the cover 12 in consideration of cost.

  For example, as shown in FIG. 3, the cover 12 covers the periphery of the core yarn 11 by knitting using a knitting yarn composed of a plurality of filaments (knitting). In this case, the knitting yarn constituting the knitted fabric is desirably 40 denier or less. When the knitting yarn has a denier of 40 denier or less, the heat of the high-temperature portion can be quickly transmitted to the core yarn 11, so that the efficiency of heat transfer is improved. On the other hand, when the knitting yarn exceeds 40 denier, the space between the high-temperature portion and the core yarn 11 becomes relatively wide, and as a result, the space (air layer) existing between the high-temperature portion and the core yarn 11 becomes large. . Therefore, when the knitting yarn exceeds 40 denier, the efficiency of heat transfer is reduced. Covering by the cover 12 is not limited to knitting. The cover 12 is provided for the purpose of making the friction coefficient of the surface lower than that of the metal thread 13 alone and preventing plastic deformation of the metal thread 13 in order to facilitate the weaving of the metal thread 13. Further, by covering the periphery of the metal thread 13 with the cover 12, the feel of the heat conduction / heat transfer region 2 can be improved.

  When the synthetic fibers of the cover 12 are weft-knitted, the coverage of the cover 12 with respect to the core yarn 11 can be increased. As a result, it is possible to suppress the core yarn 11 from jumping out of the gap of the cover 12. Here, if an excessively thin knitting yarn is used, plastic deformation of the core yarn 11 cannot be prevented because the cover 12 is thin, and the core yarn 11 jumps out of the cover 12 because the strength of the knitting yarn is low. There is a risk. Therefore, it is desirable to use a knitting yarn of 20 denier or more.

  In the case of weft knitting, the stitch is knitted so that the core yarn 11 in the vertical direction is wound around the cover 12. Therefore, the core yarn 11 can be relatively strongly tightened by the cover 12, and the degree of close contact (tightening force) of the cover 12 with the core yarn 11 can be increased. By adjusting the strength of the tension of the cover 12 when knitting the composite yarn 10, knitting can be performed so that the cover 12 appropriately adheres to the core yarn 11. As a result, the heat conductivity and heat transfer of the heat transfer / heat transfer region 2 can be improved.

  Further, when the cover 12 is melted, the permeability (permeability) of the melted cover 12 into the inside of the metal thread bundle can be increased, and the degree of adhesion between the metal thread bundle and the cover 12 can be enhanced.

  On the other hand, when the synthetic fibers of the cover 12 are weft-knitted, there is no tightening force enough to wind the synthetic fibers directly around the core yarn 11, so that damage to the core yarn 11 can be suppressed.

(Modification)
Regarding legwear 100A, 100B, 100C, and 100D, which are modifications of the legwear 100, FIGS. 4, 5A, 5B, 6A, and 6B, and FIG. This will be described based on () and (b). FIG. 4 is a right side view showing a legwear 100A which is a modification of the legwear 100. FIG. 5 (a) is a right side view showing a legwear 100B which is another modification of the legwear 100, and FIG. 5 (b) is a plan view of FIG. 5 (a) viewed from the sole side. . FIG. 6A is a right side view of a legwear 100C showing still another modification of the legwear 100, and FIG. 6B is a plan view of FIG. 6A as viewed from the sole side. . FIG. 7A is a right side view of a legwear 100D showing still another modification of the legwear 100, and FIG. 7B is a plan view of FIG. 7A as viewed from the sole side. .

  The legwear 100A is different from the legwear 100 in that the legwear 100A is provided with a heat conduction / heat transfer region 2a instead of the heat conduction / heat transfer region 2, and other configurations are the same. The legwear 100A is a high sock in which the leg portion 30 is below the knee. The heat conduction / heat transfer region 2 a is formed in a band shape and a spiral shape from the back side region of the foot at a position close to the toe portion 21 of the foot portion 20 to a position close to the opening portion 31 of the leg portion 30. . In other words, the heat conduction / heat transfer region 2a is arranged from the high-temperature part of the foot to the low-temperature part of the foot.

  In the heat conduction / heat transfer region 2a, as the distance from the relatively high temperature portion increases, the temperature difference between the relatively high temperature portion and the relatively low temperature portion increases. Since the length of the heat conduction / heat transfer region 2a is longer than that of the heat conduction / heat transfer region 2, the temperature difference between the high temperature portion and the low temperature portion increases, and heat is easily transferred. As a result, when the temperature of the sole of the foot increases due to exercise or the like, the heat of the sole of the foot can be quickly transferred to the opening 31 side.

  Conversely, when the temperature of the toe side of the foot becomes low in winter or the like, the heat of the opening portion 31 side heated by sunlight or body temperature is moved to the toe portion 21 side which is easily cooled at the end of the human body. I can do it. In other words, by using the legwear 100A, a high-temperature portion of the legwear 100A can be cooled and a low-temperature portion can be heated.

  The legwear 100B is different from the legwear 100 in that the legwear 100B is provided with a heat conduction / heat transfer region 2b instead of the heat conduction / heat transfer region 2, and other configurations are the same. The legwear 100B is a high sock in which the leg portion 30 is below the knee. As shown in FIGS. 5A and 5B, the heat conduction / heat transfer region 2b includes a sole 2b1 and a side 2b2.

  The foot sole 2b1 extends from the inside of the instep (thumb side) to the outside of the instep (thumb side) at a position close to the toe part 21 (ie, the base of the toe), and It is formed in a belt shape. The side part 2b2 is formed at two places along the inside and outside of the lower leg. The inner side 2b2 of the lower leg extends from the inner end of the sole 2b1 to the opening 31 and extends in a belt shape. The outer side 2b2 of the lower leg extends from the outer end of the sole 2b1 toward the opening 31 and extends in a belt shape. In other words, the heat conduction / heat transfer region 2b is arranged from the high-temperature part of the foot to the low-temperature part of the foot. In particular, the heat transfer is performed from the base of the toe where frictional heat is generated at the time of kicking out due to walking or the like to the ankle where cooling should be prevented.

  Since the heat conduction / heat transfer region 2b is longer than the heat conduction / heat transfer region 2, heat is easily transferred. As a result, when the temperature of the sole of the foot becomes high due to exercise or the like, the heat of the sole of the foot can be quickly moved to the opening 31 side by the heat conduction / heat transfer region 2b.

  The legwear 100C is different from the legwear 100 in that the legwear 100C includes a heat conduction / heat transfer region 2c instead of the heat conduction / heat transfer region 2, and other configurations are the same. The legwear 100C is a low socks in which the leg portion 30 extends to the ankle. As shown in FIGS. 6A and 6B, the heat conduction / heat transfer region 2c includes a sole 2c1, a side 2c2, and a back 2c3.

  The back portion 2c3 is formed in a band shape from the inside to the outside of the leg in a position close to the ankle on the Achilles tendon side of the legwear 100C so as to be substantially parallel to the ground when the legwear 100C is worn. Have been. The side portion 2c2 is formed along two places on the inside (thumb side) and outside (little finger side) of the instep. The inner side 2c2 of the instep extends in a band shape from the inner end of the back 2c3 toward the toe 21. The outer side portion 2c2 of the instep extends from the outer end of the back portion 2c3 toward the toe portion 21 in a belt shape.

  The sole 2c1 is formed in a belt shape from the inside of the instep (toe side) to the outside of the instep (toe side) at the heel (heel part) or a position close to the heel, passing through the sole area. Have been. The inner end of the sole 2c1 is connected to the inner side 2c2 of the instep, and the outer end of the sole 2c1 is connected to the outer side 2c2 of the instep. In other words, the heat conduction / heat transfer region 2c is arranged from the high-temperature part of the foot to the low-temperature part of the foot.

  Therefore, according to the heat conduction / heat transfer region 2c, even when the temperature on the heel side (heel contact portion) increases on the sole side of the foot, the heat conduction / heat transfer region 2c quickly transfers the heat on the sole side of the foot. It can be moved to the instep or the opening 31 side.

  The legwear 100D is different from the legwear 100 in that a heat conduction / heat transfer region 2d is provided instead of the heat conduction / heat transfer region 2, and other configurations are the same. The leg wear 100D is a low socks in which the leg portion 30 extends to the ankle.

  As shown in FIGS. 7 (a) and 7 (b), the heat conduction / heat transfer region 2d extends from the vicinity of the base of the middle finger of the foot to the heel at the sole of the foot, and further to the opening 31 side. The Achilles tendon extends along.

  Therefore, according to the heat conduction / heat transfer region 2d, even when the temperature increases on the sole side of the foot, the heat conduction / heat transfer region 2d can quickly move the heat on the sole side of the foot to the opening 31 side. . In particular, heat transfer is performed from the base of the toe where frictional heat is generated at the time of kicking out due to walking or the like to the ankle where cooling is to be prevented via the heel where frictional heat is generated at the time of landing.

[Embodiment 2]

The legwear 100E is different from the legwear 100 in that the legwear 100E is provided with 2e instead of the heat conduction / heat transfer region 2, and other configurations are the same.

  In the heat conduction / heat transfer region 2e, the cover 12 of the composite yarn 10 contains thermoplastic fibers. Further, the heat conduction / heat transfer region 2 e is formed by melting the cover 12. By melting the cover 12, the air layer between the metal thread 13 and the cover 12 is eliminated, and the entire cover 12 and the metal thread 13 can be brought into close contact. As a result, the heat conductivity / heat transfer property of the heat transfer / heat transfer region 2e is improved, and the speed of heat transfer can be increased.

  The legwear 100E includes a main body 1 and a heat conduction / heat transfer area 2e, and the heat conduction / heat transfer area 2e and the main body 1 are continuously integrated in the same plane. The legwear 100E is formed by heat-treating the composite yarn 10 located in the region of the heat conduction / heat transfer region 2e, so that the main body 1 and the heat conduction / heat transfer region 2e are continuously integrated. Therefore, the heat conduction / heat transfer region 2e can be formed at a desired position of the legwear 100E without adding an external member, so that a problem caused by the addition of the external member can be avoided.

  The heat conduction / heat transfer region 2e is formed by completely melting the thermoplastic fiber so that no fiber remains, and wrapping the core yarn around the yarn at the boundary between the main body 1 and the heat conduction / heat transfer region 2e. It is desirable to fuse the thermoplastic fibers that have been melted. Thereby, the connection between the main body 1 and the heat conduction / heat transfer region 2e becomes stronger.

  Further, by melting and processing the entire surface (front side and back side) of the heat conduction / heat transfer region 2e, the planar heat conduction / heat transfer region 2e can be formed. Thereby, the area of the heat conduction / heat transfer region 2e is increased, and the heat conductivity / heat transfer property can be improved.
