When exercising, it is required to improve physical ability. When muscles are warmed up, they are encouraged to increase their power output and promote super-recovery. This is because muscles are made up of chemical substances, and when the temperature rises, they enter a high-energy state, speeding up chemical reactions and speeding up nerve transmission and muscle movement. When the whole body is warmed, the temperature of the muscles rises, and muscle output and super-recovery are promoted. However, when the temperature inside the body (deep temperature) rises, it feels hot, thermal comfort decreases, and physical performance decreases. If exercise is continued while the whole body is warmed, the core temperature rises further, leading to heat fainting, heat cramps, heat exhaustion, and heat stroke, making exercise itself difficult.
The present invention warms the active muscles during exercise, improves muscle output, and promotes super-recovery while radiating heat from the heat-dissipating part, thereby suppressing the rise in deep-body temperature and maintaining thermal comfort. Provide clothing that allows you to continue exercising.

The present invention includes a heat-retaining fabric portion and a heat-dissipating fabric portion, wherein the heat-retaining fabric is positioned to cover at least a portion of the quadriceps, and the heat-dissipating portion is positioned to cover at least a portion of the ilium. Tights with sexual fabrics. By arranging the heat-retaining fabric on the quadriceps muscles, which are the main muscles of the lower body, it is possible to increase physical ability for various movements. Also, by arranging the heat-dissipating fabric at a position covering at least a part of the ilium, the heat-dissipating portion in the vicinity of the ilium can be efficiently cooled. The ilium is located near the common aorta and the inferior vena cava and has thick blood vessels, so it is susceptible to heat-dissipating sites and can be efficiently cooled. Preferably, the heat-dissipating fabric is placed at a position that at least partially covers the external iliac vein on the ilium. The external iliac vein on the ilium is located near the inferior vena cava, has thick blood vessels, is easily affected by heat-dissipating sites, and can be efficiently cooled. This form is effective for short tights, half-length tights above the knee, three-quarter length tights below the knee, and half pants. In addition, these tights can shorten the warm-up time, leaving sufficient energy for the competition, and allowing the athlete to continue playing the sport. In addition, other than the heat-retaining fabric part and the heat-dissipating fabric part, the fabric used for normal sports tights can be placed. This is the same for other examples of tights. In this specification, tights are a concept including pants.

In the present invention, it is preferable to further arrange the heat-retaining fabric at a position covering at least a portion selected from the biceps femoris muscle, the semimembranosus muscle, and the semitendinosus muscle. This can improve the reactivity, operability, and muscle strength of the lower limbs. These forms are effective for short tights, half-length tights above the knee, and three-quarter length tights below the knee.
It is preferable that the tights of the present invention further include heat-retaining fabric at a position covering at least a portion of the triceps surae. Thereby, reactivity, operability, and muscle strength of the lower limbs can be improved. This form is effective for long tights up to the ankle.

In the tights of the present invention, it is preferable that a heat-dissipating fabric is further arranged at a position covering at least a portion selected from the gluteus maximus and the gluteus medius. As a result, it is possible to suppress an increase in the deep temperature of the body. This form is effective for any tights.

The tights of the present invention preferably further include heat-dissipating fabric positioned to cover at least a portion of the lesser saphenous vein near the Achilles tendon of the lower leg. Due to the length of the leg, it is preferable to place the heat dissipating site in the lesser saphenous vein near the Achilles tendon of the lower leg for more efficient cooling to the extremities. It is a large vein in the leg and connects with the femoral vein, so if the lesser saphenous vein cools the blood, the femoral vein cools it more. This form is effective for long tights up to the ankle and warm-up pants.

The heat-retaining fabric should preferably have a smaller space in the garment between the specified muscles. The space inside the clothes is preferably 20 mm or less, more preferably 10 mm or less, and may be in direct contact. By doing so, the heat-retaining fabric makes it easier to warm the muscles in the necessary areas while suppressing heat dissipation.

It is preferable that the heat-retaining fabric has water absorbency. When the temperature of the muscles is increased, sweat in the liquid phase is generated on the skin surface. If there is no water absorbency, sweat remains on the skin surface and absorbs heat from the muscles, which lowers the temperature of the muscles, which is not preferable. The water absorption is preferably within 60 seconds, more preferably within 30 seconds, according to the JIS L 1907 dropping method.

Preferably, the heat-retaining fabric covers 50% or more of the designated muscles in the body part covered by the garment. More preferably, it covers 70% or more. By doing so, it is possible to heat the key points of the designated muscles.

The heat-retaining fabric should have a smaller amount of heat dissipation. The heat radiation amount is preferably 2.0 W or less, more preferably 1.8 W or less. The amount of heat dissipation indicates the power consumption when the heat retention evaluation device in KES-F7 manufactured by Kato Tech Co., Ltd. in accordance with JIS L 1927 is set to ΔT = 20°C. This power consumption quantifies the phenomenon of heat dissipation through the fabric, and the smaller the value, the better the heat retention by the fabric.

The heat-retaining fabric is preferably the fabric exemplified below.
(1) Moisture-absorbing and heat-generating fabric The moisture-heat-generating fabric is a fabric containing highly crosslinked polyacrylate fibers. Since highly crosslinked polyacrylate fibers alone generate enough heat to cause burns, they are usually blended with polyester fibers in an amount of 10 to 40% by mass and spun to form woven or knitted fabrics. It is manufactured by Mitsuno Co., Ltd. and is commercially available under the trade name "Breath Thermo".
(2) Fiber fabrics with low thermal conductivity Fibers with low thermal conductivity include wool with a thermal conductivity of 0.19, Nylon 0.22, polyester 0.25 (both units are kcalm ^-1 h ^-1 ° C. ^-1 ), and these can be used. In addition, according to "Plastic Data Book", page 60, published on January 20, 2006, by the Industrial Research Institute, the thermal conductivity of polypropylene is 0.12 W/m·°C, and polypropylene fibers can also be used.
(3) Fiber Fabric Containing Heat Storage Fiber The heat storage fiber fabric is a fabric containing fibers spun by kneading a heat storage substance into a polymer. For example, it is a fabric containing fibers spun by kneading ceramic fine particles, graphite silica fine powder, volcanic ash, tungsten fine powder, or the like.

(6) Vapor-Deposited Fabric with Radiation Effect Vapor-deposited fabric with radiation effect can be made of fibers or fabrics on which metal such as aluminum is vapor-deposited.
(7) Fabric with Low Air Permeability The fabric with low air permeability is preferably a fabric with air permeability defined by the Frazier method of JIS L 1096 of 150 cm ³ /cm ² ·sec or less. The lower the air permeability, the higher the heat retention, but the more damp feeling inside the clothes, so the lower limit is preferably 1 cm ³ /cm ² ·sec or more.
One or a combination of two or more of the above can be used.

The heat-dissipating fabric covers at least a portion of the ilium. Preferably, the heat-dissipating fabric is positioned over a portion of the external iliac vein on the ilium. The external iliac vein connects with the inferior vena cava, one of the thickest blood vessels just below the heart, and the heat-dissipating fabric efficiently returns cooled blood to the heart, suppressing the rise in core temperature. do. More preferably, a part of the femoral vein branching from the external iliac vein is also arranged with the heat-dissipating fabric, so that the blood can be cooled more efficiently. Even more preferably, a portion of the lesser saphenous vein branching from the femoral vein is also provided with the heat-dissipating fabric so that the blood can be cooled more efficiently. However, if the blood vessels are not covered with tights or underpants, the blood can be cooled by outside air without placing the heat-dissipating fabric. Preferably, the garment covers 50% or more of the designated blood vessels in the body part covered. More preferably, it covers 70% or more. By doing so, it is possible to efficiently dissipate heat from the designated main portion of the blood vessel.

The heat-dissipating fabric should be as large as possible. The heat radiation amount is preferably 1.0 W or more, more preferably 1.2 W or more. The amount of heat dissipation indicates the power consumption when the heat retention evaluation device in KES-F7 manufactured by Kato Tech Co., Ltd. in accordance with JIS L 1927 is set to ΔT = 20°C. This power consumption quantifies the phenomenon of heat dissipation through the fabric, and the larger the value, the more heat is dissipated by the fabric.

The heat-dissipating fabric is preferably the fabric exemplified below.
(1) Fabric Containing Fast-Drying Fibers Fabrics containing fast-drying fibers include, for example, polyester water-absorbing and quick-drying treated fabrics. This fabric easily dries moisture such as sweat, and dissipates heat from the human body through latent heat of evaporation during drying. As an example, it is obtained by processing a hydrophilic polyester resin. The hydrophilic polyester resin processing agent to be used absorbs (exhausts and diffuses) at least a portion of the processing agent into the polyester fiber due to the same function as disperse dyes. This hydrophilic polyester resin processing agent is a linear copolymer in which terminal groups of a polyester group and a hydrophilic group are bonded to each other. Block copolymers are preferred. The molecular weight is preferably 5000-8000, more preferably 6000-7000. The weight ratio of polyester groups and hydrophilic groups is preferably 90/10 to 10/90, more preferably 60/40 to 20/80. Hydrophilic groups include polyethylene glycol, 5-sulfoisophthalic acid-sodium, trimellitic anhydride and the like, with polyethylene glycol being more preferred. As such a processing agent, there is product number KMZ-902 manufactured by Takamatsu Yushi Co., Ltd.
The water absorption is preferably within 20 seconds, more preferably within 10 seconds, according to the JIS L 1907 dropping method. As for the quick-drying property, the drying time according to the ISO 17617-2014 A1 method is preferably 80 minutes or less, more preferably 70 minutes or less. By doing so, water absorption, diffusion, and quick drying are combined, and the latent heat of evaporation lowers the temperature of the fabric and dissipates heat from the human body.
(2) Fabrics containing highly thermally conductive fibers Fabrics containing highly thermally conductive fibers are described in the Textile Handbook, edited by the Society of Fiber Science and Technology, 3rd edition, p.462, published on December 15, 2004. The conductivity is 0.56 kcalm ⁻¹ h ⁻¹ ° C. ⁻¹ ), and rayon is comparable and can be used. Also, "Plastic Data Book", page 60, published 2006.1.20, according to the Industrial Research Institute, the thermal conductivity of polyethylene is 0.33 W/m・℃ for LDPE and 0.46-0.50 W/m・℃ for HDPE. Yes, polyethylene fibers can also be used. Ethylene vinyl alcohol fibers, derived from ethylene fibers, can also be used. It is commercially available from Kuraray Co., Ltd. under the trade name 'Sophista'.
(3) Fabric with a thin thickness A fabric that is relatively thin compared to the heat-retaining fabric can also be used. The thickness of the heat-dissipating fabric is preferably 0.1 mm or more thinner than the heat-retaining fabric, more preferably 0.13 mm or more, and still more preferably 0.15 mm or more.
(4) Highly Breathable Fabric The highly breathable fabric preferably has an air permeability of 100 cm ³ /cm ² ·sec or more as defined by the Frazier method of JIS L 1096. The higher the air permeability, the higher the heat dissipation, but the lower the strength of the fabric, so the upper limit is preferably 500 cm ³ /cm ² ·sec or less.
(5) Fabrics containing cooling fibers Cellulose fibers such as cotton and rayon are hydrophilic fibers that have the property of not separating when they absorb liquid water, and are cold when wet. It may be a fabric containing
One or a combination of two or more of the above can be used. Among these, polyester water-absorbing and quick-drying treated fabric is preferable.

It is also preferable that the heat-retaining fabric and the heat-dissipating fabric have the following relationship.
(1) Heat-retaining fabric-heat-dissipating fabric>there is a thickness difference of 0.1 mm.
The greater the thickness, the more dead air is stored and the heat insulation increases. Since the heat-retaining fabric is thicker than the heat-dissipating fabric, the heat inside the clothes does not easily escape to the outside of the clothes, raising the temperature of the muscles while suppressing the rise of the core temperature. If the difference in thickness is less than 0.1 mm, the difference in heat insulation is small, and it becomes impossible to properly raise the muscle temperature or maintain the core temperature. In a hot environment, the thickness of both the heat-retaining fabric and the heat-dissipating fabric is thin. If the thickness difference between the heat-dissipating fabric and the heat-dissipating fabric is greater than 0.1 mm, it can have a function.
(2) There is a heat dissipation difference of 0.3W between the heat dissipating fabric and the heat retaining fabric.
The amount of heat dissipation indicates the power consumption when the heat retention evaluation device in KES-F7 manufactured by Kato Tech Co., Ltd. conforming to JIS L 1927 is set to ΔT = 20°C. This power consumption quantifies the phenomenon of heat dissipation through the fabric, and the larger the value, the more heat is dissipated by the fabric. If the difference in the amount of heat released is within 0.3 W, it will not be possible to properly increase the muscle temperature or maintain the core temperature. In a hot environment, the heat dissipation amount of both heat-retaining fabric and heat-dissipating fabric is small, and in a cold environment, the heat-dissipating amount of both heat-retaining fabric and heat-dissipating fabric is increased. , if the heat dissipation difference between the heat insulating fabric and the heat dissipating fabric is greater than 0.3W, it can have a function.
(3) Heat-dissipating fabric-Insulating fabric>There is a difference in air permeability of >50 cm ³ /cm ² ·sec.
The air permeability indicates the value obtained by the JIS L1096 air permeability test. The higher the air permeability, the easier it is for air outside the clothing to enter the clothing, resulting in greater heat dissipation. If the difference in air permeability is within 50 cm ³ /cm ² ·sec, it will not be possible to properly raise the muscle temperature or maintain the core temperature. In a hot environment, the air permeability of both the heat-retaining fabric and the heat-dissipating fabric is low, and in the cold environment, the air-permeability of both the heat-retaining fabric and the heat-dissipating fabric is increased, so that the clothing can be designed according to the environment. , if the difference in air permeability between the heat-insulating fabric and the heat-dissipating fabric is greater than 50 cm ³ /cm ² ·sec, it can have a function.

The space in the tights is preferably 20 mm or less, more preferably 10 mm or less, and may be in direct contact. By doing so, the heat-retaining fabric makes it easier to warm the muscles in the necessary areas while suppressing heat dissipation. In addition, the heat-dissipating fabric promotes the heat-dissipating properties of the blood vessels at the necessary sites, and can suppress the rise of the deep temperature.

For sewing, there are a method of sewing threads, a method of adhering hot melt, and a method of dissolving and connecting fabrics.

Clothes that have almost no internal space and are in close contact with the body are called compression-type clothes, and have a shape that is efficient in retaining heat in muscles and dissipating heat in blood vessels. When forming a compression type, improve the stretchability of the fabric with a large area to be used. Stretchability is measured based on JIS L 1096 8.14.1 A method under the conditions of a load of 17.6 N and a tensile speed of 200 mm / min, and the elongation in the width direction is 50% or more. It is suitable to have By doing so, when wearing a compression type that is equal to or slightly smaller than the nude size of the body, the body and clothes are in close contact but do not hinder mobility.
In the type where the space inside the garment is 20 mm or less and is more roomy than the compression type, the stretchability of the fabric is based on JIS L 1096 8.14.1 A method, load 17.6 N, tensile speed 200 mm / min. Using the elongation measured below, a widthwise elongation of 10% or more is suitable.
