However, in the above-mentioned prior art, a portion requiring heat retention during exercise and a portion requiring heat dissipation have not been selected, and further improvement has been required.

In the present invention, in order to solve the above-mentioned conventional problems, a part requiring heat retention and a part requiring heat dissipation during exercise are selected, and a heat-retaining fabric is placed in the part requiring heat retention to dissipate heat. Provide a shirt with heat dissipation in the areas where it is needed.

The shirt of the present invention is a shirt including a heat-retaining fabric portion and a heat-dissipating fabric portion, and the heat-retaining material is located at a position covering most of the pectoralis major muscle of the front body, an upper part of the back body, and a position covering the upper arm portion. Place the sex fabric, and place the heat-dissipating fabric at the position where it passes from the shoulder of the back body to the back side, covers at least a part of the infraspinatus muscle, and connects to the side part and the lower part of the back body , and the front body and upper arm part. The heat-retaining fabric is continuous, and the heat-retaining fabric of the back body and the upper arm is separated by the heat-dissipating fabric .

In the shirt of the present invention, the heat-retaining fabric is placed at a position that covers at least a part of the pectoralis major muscle, and the heat-dissipating cloth is placed at a position that covers at least a part of the side part, so that the agonist muscle during exercise can be arranged. By warming, improving muscle output, and promoting recovery, by dissipating heat from the heat dissipating site, it is possible to provide a shirt that can suppress the rise in deep temperature and continue exercising without deteriorating thermal comfort. .. In addition, the warm-up time can be shortened and the sport can be continued as it is.

FIG. 2A is a schematic front view of the shirt according to another embodiment of the present invention, and FIG. 2B is a schematic rear view of the shirt. FIG. 3A is a schematic front view of the shirt according to still another embodiment of the present invention, and FIG. 3B is a schematic rear view of the shirt. 4A is a schematic front view of the shirt according to still another embodiment of the present invention, and FIG. 4B is a schematic rear view of the shirt. FIG. 5 is a muscular diagram of the upper body of the human body as seen from the front. FIG. 6 is a muscular diagram of the upper body of the human body as seen from the rear.

It is required to improve physical ability during exercise. As the temperature of muscles rises, it promotes increased output and supercompensation. This is because muscles are composed of chemical substances, and when the temperature rises, they become in a state of high energy and the chemical reaction becomes faster, so that the transmission by nerves and the movement of muscles become faster. When the whole body is warmed, the temperature of the muscle rises, and the output and supercompensation of the muscle are promoted. However, as the temperature inside the body (deep temperature) rises, the feeling of being hot lowers the thermal comfort and the physical ability. If you continue exercising with your whole body warm, the deep temperature will rise further, resulting in heat loss, heat cramps, heat exhaustion, and heat stroke, making the exercise itself difficult.
The present invention warms the agonist muscles during exercise, improves muscle output, and promotes supercompensation, but by dissipating heat from the heat-dissipating site, it suppresses the rise in deep temperature and does not reduce 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, the heat-retaining fabric is arranged at a position covering at least a part of the pectoralis major muscle, and the heat-dissipating fabric is arranged at a position covering at least a part of the side portion. It is a shirt in which. As a result, by arranging the heat-retaining fabric on a part of the pectoralis major muscle, which is the main muscle of the upper body, it is possible to improve the physical ability against various movements. Further, by arranging the heat-dissipating dough at a position covering at least a part of the armpit, the heat-dissipating portion of the axillary vein can be efficiently cooled. Since the axillary vein is located near the superior vena cava, the blood vessel is thick, and it is located near the surface layer of the skin, it is easily affected by the heat-dissipating site and can be cooled efficiently. This form is effective for sleeveless shirts. In addition, this shirt can shorten the warm-up time, leave enough room for competition, and continue sports as it is. In addition, except for the heat-retaining fabric portion and the heat-dissipating fabric portion, the fabric used for a normal sports shirt can be arranged. This is the same for the shirts of other examples.

In the present invention, it is preferable to further arrange the heat insulating fabric at a position covering at least a part of the deltoid muscle. The deltoid muscles are located on the shoulders and can improve your physical ability against various movements. Further, it is preferable to arrange the heat insulating fabric at a position covering at least a part of the biceps brachii muscle and the triceps brachii muscle. This makes it possible to improve the responsiveness, operability, and muscle strength of the upper limbs by arranging the heat-retaining fabric on the main deltoid muscles, biceps brachii muscles, and triceps brachii muscles in the operation of the upper limbs. These forms are effective for short-sleeved shirts, seven-sleeve shirts, and long-sleeved shirts.

In the shirt of the present invention, it is preferable to place the heat-dissipating fabric at a position that further covers at least a part of the infraspinatus muscle from the shoulder portion and connects to the armpit portion. Furthermore, it is preferable to place a heat-dissipating fabric on the abdomen of the front body. As a result, it is possible to suppress an increase in the deep temperature of the body. These forms are effective for sleeveless shirts, short-sleeved shirts, seven-sleeve shirts, and long-sleeved shirts.

In the shirt of the present invention, it is preferable to further arrange the heat-retaining fabric on the upper part of the back body and the heat-dissipating fabric on the lower part of the back body. This warms the agonist muscles during exercise, improves muscle output, and promotes supercompensation, but by dissipating heat from the heat-dissipating site, it suppresses the rise in deep temperature and does not reduce thermal comfort. You can continue exercising. More preferably, the heat-retaining dough is placed on at least a part of the trapezius muscle, and the heat-dissipating dough is placed on at least a part of the thoracolumbar fascia. This form is effective for sleeveless shirts, short-sleeved shirts, seven-sleeve shirts, long-sleeved shirts, and warm-up shirts.

The smaller the space inside the garment with the designated muscle, the better the heat-retaining fabric. The space inside the clothes is preferably 20 mm or less, more preferably 10 mm or less, and may be brought into direct contact with the clothes. By doing so, the heat-retaining fabric makes it easier for the muscles in the required area to be heated while suppressing heat dissipation.

The heat-retaining fabric is preferably water-absorbent. When the temperature of the muscle is raised, liquid phase sweat is generated on the surface of the skin. If there is no water absorption, sweat remains on the surface of the skin and absorbs the heat of the muscle, which lowers the temperature of the muscle, which is not preferable. The water absorption is preferably within 60 seconds, more preferably within 30 seconds by the JIS L 1907 dropping method.

The heat insulating fabric preferably covers 50% or more of the designated muscles in the body part covered by the garment. More preferably, it is better to cover 70% or more. By doing so, it is possible to keep the main part of the designated muscle warm.

The smaller the amount of heat radiation, the better the heat-retaining fabric. The amount of heat released is preferably 2.0 W or less, more preferably 1.8 W or less. The amount of heat radiation indicates the power consumption when the heat retention evaluation device in KES-F7 manufactured by Katou Tech Co., Ltd. conforming to JIS L 1927 is set to ΔT = 20 ° C. This power consumption is a quantification of the phenomenon that heat is dissipated through the dough, and the smaller the value, the more heat can be kept by the dough.

The heat-retaining fabric is preferably the fabric exemplified below.
(1) Moisture-absorbing heat-generating fabric The moisture-absorbing heat-generating fabric is a fabric containing highly crosslinked polyacrylate fibers. Highly cross-linked polyacrylate fibers alone generate heat to the extent that they burn, so they are usually mixed with polyester fibers in an amount of 10 to 40% by mass and spun to form a woven fabric or knitted fabric. Made by Mizuno Co., Ltd., and marketed under the trade name "Breath Thermo".
(2) Fiber fabric with low thermal conductivity As a fiber with low thermal conductivity, "3rd Edition Textile Handbook" edited by the Textile Society, p. 462, published on December 15, 2004, according to Maruzen, the thermal conductivity is wool 0.19, Nylon 0.22 and polyester 0.25 (both units are kcalm ^-1 h ^-1 ° C ^-1 ), and these can be used. According to "Plastic Data Book", page 60, published on January 20, 2006, Kogyo Chosakai, the thermal conductivity of polypropylene is 0.12 W / m · ° C, and polypropylene fiber 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 fine ceramic particles, fine graphite silica stone powder, volcanic ash, fine tungsten powder, and the like.
(4) Fabrics with swelling Fabrics with swelling include boa cloth, pile cloth, standing blanket, knotted double cloth, and stretchable knitted fabric using tentative crimped yarn.
(5) Fabric that makes point contact The fabric that makes point contact with the skin of the human body may be formed by a woven structure or a knitted structure, or may be formed by embossing.
(6) Thin-film deposition processed fabric having a radiant effect The vapor-deposited fabric having a radiant effect can be formed of fibers or woven fabrics on which a metal such as aluminum is vapor-deposited.
(7) Fabric with low air permeability The fabric with low air permeability is preferably a fabric having a breathability of 150 cm ³ / cm ² · sec or less specified by the Frazier method of JIS L 1096. The lower the air permeability, the higher the heat retention, but the feeling of stuffiness in the clothes increases, so the lower limit is preferably 1 cm ³ / cm ² · sec or more.
From the above, 1 or 2 or more can be used in combination.

The heat-dissipating dough covers at least a portion of the axillary vein. The axillary vein connects to the superior vena cava, one of the thickest blood vessels beneath the heart, allowing blood cooled by the heat-dissipating dough to efficiently return to the heart and suppress the rise in deep temperature. However, if the above blood vessels are not covered with a shirt, the blood can be cooled by the outside air without arranging the heat-dissipating fabric. It is preferable to cover 50% or more of the designated part in the body part covered by the clothes. More preferably, it covers 70% or more. By doing so, heat can be efficiently dissipated to the main part of the designated blood vessel. The larger the amount of heat dissipated, the better the heat-dissipating fabric. The amount of heat radiation is preferably 1.0 W or more, more preferably 1.2 W or more. The amount of heat radiation indicates the power consumption when the heat retention evaluation device in KES-F7 manufactured by Katou Tech Co., Ltd. conforming to JIS L 1927 is set to ΔT = 20 ° C. This power consumption is a quantification of the phenomenon that heat is dissipated through the dough, and the larger the value, the more the heat can be dissipated by the dough.

As the heat-dissipating dough, the dough exemplified below is preferable.
(1) Fabric containing fibers having high quick-drying As the fabric containing fibers having high quick-drying property, for example, polyester water-absorbing quick-drying fabric may be used. This fabric easily dries moisture such as sweat, and dissipates the heat of the human body by the latent heat of vaporization during drying. As an example, it is obtained by processing a hydrophilic polyester resin. The hydrophilic polyester resin processing agent used has the same function as the disperse dye, and at least a part of the processing agent is absorbed (absorption diffusion) in the polyester fiber. This hydrophilic polyester resin processing agent is a linear copolymer in which a polyester group and a terminal group of a hydrophilic group are bonded to each other. It is preferably a block copolymer. The molecular weight is preferably 5000 to 8000, more preferably 6000 to 7000. The weight ratio of the polyester group to the hydrophilic group is preferably 90/10 to 10/90, more preferably 60/40 to 20/80. Examples of the hydrophilic group include polyethylene glycol, 5-sulfoisophthalic acid-sodium, trimellitic anhydride and the like, and polyethylene glycol is more preferable. As such a processing agent, there is a product number KMZ-902 manufactured by Takamatsu Oil & Fat Co., Ltd.
The water absorption is preferably within 20 seconds, more preferably within 10 seconds by the JIS L 1907 dropping method. The quick-drying property is based on the ISO 17617-2014 A1 method, and the drying time 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 temperature of the dough is lowered by the latent heat of vaporization, and the heat of the human body is dissipated.
(2) Fabric containing fibers with high thermal conductivity The fabric containing fibers with high thermal conductivity is the heat of cotton according to Maruzen, "3rd Edition Textile Handbook" edited by the Textile Society, p. 462, 2004.12.15. The conductivity is 0.56 kcalm ^-1 h ^-1 ° C ^-1 ), and rayon is about the same, so these can be used. According to the "Plastic Data Book", p. 60, published on January 20, 2006, the thermal conductivity of polyethylene is 0.33 W / m · ℃ for LDPE and 0.46-0.50 W / m · ℃ for HDPE. Yes, polyethylene fiber can also be used. Ethylene vinyl alcohol fiber derived from ethylene fiber can also be used. It is manufactured by Kuraray Co., Ltd. and is commercially available under the trade name'Sofista'.
(3) Thin fabric A fabric that is relatively thinner than the heat-retaining fabric can also be used. The thickness of the heat-dissipating dough is preferably 0.1 mm or more thinner than the heat-retaining dough, more preferably 0.13 mm or more, and further preferably 0.15 mm or more.
(4) Highly breathable fabric The highly breathable fabric is preferably a fabric having a breathability of 100 cm ³ / cm ² · sec or more specified by the Frazier method of JIS L 1096. The higher the air permeability, the higher the heat dissipation, but the strength of the fabric decreases, 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 and have the property of not separating when they absorb the moisture of the liquid, and they are cold in a wet state. The dough may be included.
From the above, 1 or 2 or more can be used in combination. Of these, polyester water-absorbent quick-drying 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 difference in thickness of 0.1 mm.
The thicker it is, the more dead air is stored and the better the heat insulation. Since the heat-retaining fabric is thicker than the heat-dissipating fabric, the heat inside the clothes is less likely to escape to the outside of the clothes, and the temperature of the muscles is raised while suppressing the rise in the deep temperature. When the difference in thickness is within 0.1 mm, the difference in heat insulating property is small, and it becomes impossible to raise the temperature of the muscle properly or maintain the deep temperature. In a hot environment, both the heat-retaining fabric and the heat-dissipating fabric are thin, and in a cold environment, both the heat-retaining fabric and the heat-dissipating fabric are thick, so that the clothes can be designed according to the environment. If the difference in thickness between the sex fabric and the heat-dissipating fabric is larger than 0.1 mm, it has a function.
(2) Heat-dissipating fabric-heat-retaining fabric> There is a difference in the amount of heat radiation of 0.3W.
The amount of heat radiation indicates the power consumption when the heat retention evaluation device in KES-F7 manufactured by Katou Tech Co., Ltd. conforming to JIS L 1927 is set to ΔT = 20 ° C. This power consumption is a quantification of the phenomenon that heat is dissipated through the dough, and the larger the value, the more the heat can be dissipated by the dough. If the difference in the amount of heat radiation is within 0.3 W, the proper muscle temperature rise or the deep temperature cannot be maintained. In a hot environment, the heat dissipation of both the heat-retaining fabric and the heat-dissipating fabric is small, and in a cold environment, the heat-dissipating fabric and the heat-dissipating fabric both have a large heat dissipation amount, so that the clothes can be designed according to the environment. If the difference in the amount of heat dissipated between the heat-retaining fabric and the heat-dissipating fabric is larger than 0.3 W, the fabric has a function.
(3) Heat-dissipating fabric-heat-retaining fabric> There is a difference in air permeability of 50 cm ³ / cm ² · sec.
The air permeability is a value according to the JIS L1096 air permeability test. The higher the air permeability, the easier it is for the air outside the clothes to enter the clothes, and the greater the heat dissipation. If the difference in air permeability is within 50 cm ³ / cm ² · sec, it will not be possible to raise the proper muscle temperature or maintain the deep temperature. In a hot environment, the air permeability of both the heat-retaining fabric and the heat-dissipating fabric is small, and in a cold environment, the air permeability of both the heat-retaining fabric and the heat-dissipating fabric is increased, so that the clothes can be designed according to the environment. If the difference in air permeability between the heat-retaining fabric and the heat-dissipating fabric is larger than 50 cm ³ / cm ² · sec, it has a function.

The space inside the garment is preferably 20 mm or less, more preferably 10 mm or less, and the shirt may be brought into direct contact with the shirt. By doing so, the heat-retaining fabric makes it easier for the muscles in the required area to be heated while suppressing heat dissipation. In addition, the heat-dissipating dough promotes the heat-dissipating property of the blood vessels in the required portion, and can suppress the rise in the deep temperature.

In forming garments, a method of stitching together a heat-retaining fabric and a heat-dissipating fabric by sewing, a method of creating the entire garment with a heat-dissipating fabric and sewing the heat-retaining fabric where necessary, and keeping the entire garment heat-retaining. There is a method of making with dough and partially dissolving and excising the necessary part. Sewing includes a method of sewing threads, a method of adhering hot melt, and a method of melting and connecting fabrics to each other.

Clothes that have almost no space inside the clothes and are in close contact with the body are called compression type, and have an efficient shape for heat retention of muscles and heat dissipation of blood vessels. When forming a compression type, improve the stretchability of the fabric that uses a large area. For stretchability, the elongation rate in the width direction is 50% or more using the elongation rate measured under the conditions of a load of 17.6 N and a tensile speed of 200 mm / min based on the JIS L 1096 8.14.1 A method. It is suitable to have. By doing so, when the compression type, which is made slightly smaller than the nude size of the body, is attached, the body and clothes are in close contact with each other, but the motility is not impaired. In the type where the space inside the clothes is 20 mm or less and there is more room than the compression type, the stretchability of the fabric is based on the 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. It is suitable that the elongation rate in the width direction is 10% or more using the elongation rate measured below.

The shirt of the present invention is preferably a sports shirt. Sleeveless shirts, short-sleeved shirts, seven-sleeve shirts, long-sleeved shirts, and warm-up shirts are preferred. These shirts may be made by stitching a heat-retaining fabric, a heat-dissipating fabric, and a normal shirt fabric by sewing if necessary, or the entire shirt may be sewn with a heat-dissipating fabric to retain heat where necessary.

Ten healthy male subjects wore Example 1 and Comparative Example 1, rested for 30 minutes, and then evaluated by push-ups. The time until the start of the movement and the time for one push-up when the movement was started by the sound signal were compared and evaluated, and the average value was compared. The results are as follows.
-Time until the start of operation Example 1 <Comparative Example 1
-One push-up time Example 1 <Comparative Example 1
In Example 1, it was confirmed that the heat-retaining fabric increased the temperature of the muscles and increased the reaction and output of the muscles, so that the time until the start of the operation and the time for one push-up were shortened.
Next, a comparative evaluation of the thermal comfort of the body was performed when push-ups were performed 50 times with a rhythm of 1 time / 1 second. The results are as follows.
-Example 1: Slightly warm-Comparative Example 1: Slightly warm In Example 1, the blood vessels could be efficiently cooled by the heat-dissipating dough, and the thermal comfort was about the same as in Comparative Example 1.
Next, 10 healthy male subjects wore Example 2 and Comparative Example 2, rested for 30 minutes, and then evaluated by push-ups. The time until the start of the movement and the time for one push-up when the movement was started by the sound signal were compared and evaluated, and the average value was compared. The results are as follows.
-Time until the start of operation Example 2 <Comparative Example 2
-One push-up time Example 2 <Comparative Example 2
In Example 2, the heat-retaining fabric increased the temperature of the muscles, and the reaction and output of the muscles increased, so that the time until the start of movement and the time for one push-up were shortened.
Next, a comparative evaluation of the thermal comfort of the body was performed when push-ups were performed 50 times with a rhythm of 1 time / 1 second. The results are as follows.
-Example 2: Slightly warm-Comparative Example 2: Slightly warm In Example 2, the blood vessels could be efficiently cooled by the heat-dissipating dough, and the thermal comfort was about the same as in Comparative Example 2.

Based on the above evaluation, the shirt of this example warms the agonist muscles during exercise, promotes muscle output improvement and recovery, and suppresses the rise in deep temperature by dissipating heat from the heat dissipating site. It was confirmed that the exercise could be continued without deterioration of thermal comfort, the warm-up time could be shortened, and the sport could be continued as it was.

The shirt of the present invention can be applied to various shirts such as sleeveless shirts, short-sleeved shirts, seven-sleeve shirts, and long-sleeved shirts. It is also suitable as an inner shirt for baseball, soccer, rugby, marathon, running, walking, cycling, mountain climbing, tennis, etc.
