Description

  The present invention relates to a garment with a sleeve, and more particularly, to a garment with a sleeve that can prevent a temperature drop of the hand, and in particular, is an underwear suitable for being worn under a bedding during sleep.

When the temperature is low, cold hands may become an obstacle to sleep. This is because when the peripheral blood vessels such as the hands are expanded and warmed at bedtime and the temperature of the trunk is kept low, sleep can be done smoothly and deep sleep can be obtained, This is because it is difficult to sleep smoothly in a state where the blood vessels are contracted, and it is difficult to obtain deep sleep.
If you feel the coldness of your hands during sleep, you may wear an underwear under the bedding and go to bed, or warm your body in the bath before going to bed.
In addition, when the user is out of the winter, the exposed hand may get cold even during sleep.

If you wear warm insulation underwear to prevent your hands from getting cold during sleep, or if you put on underwear, the core temperature will rise and you will not be able to get a deeper sleep than it will be. In addition, when layered, the feeling of wearing becomes worse, and it becomes difficult to move or stiff shoulders.
The underwear for warming is usually used to warm the entire body by using a material with a high heat retention rate, thickening the material, or raising the material. This is preferable. However, in order to eliminate the cold at the hands that are exposed to the outside, it is generally too hot when wearing heat-insulating underwear.
Wearing gloves to prevent cold hands is done in winter, but wearing gloves to prevent cold hands during sleep is uncomfortable, and conversely If you sleep while sleeping, it is often too hot.

Conventionally, in Japanese Utility Model Publication No. 63-42105 (Patent Document 1), as shown in FIG. 7, the entire inner side of the elbow portion of the underwear body 1 made of a knitted fabric is used to relieve joint pain due to rheumatism, neuralgia and the like ( A cylindrical knitted fabric 3 is integrally provided on the inner peripheral surface, and a supporter function is given to the inner cylindrical knitted fabric 3.
However, Patent Document 1 does not disclose an appropriate heat retention rate of the underwear body and the tubular knitted fabric. In order to relieve joint pain, it is desirable that the heat retention rate of the tubular knitted fabric is high. However, if the heat retention rate is too high, there is a problem that the knitted fabric becomes too thick and the comfort becomes worse.

Japanese Utility Model Publication No. 63-42105

  The present invention has been made in view of the above-described problems, and can keep the hand in a warm state, while being able to sufficiently prevent the heat-retaining effect on the trunk from becoming excessive, and comfort for the wearer. It is an object of the present invention to provide a sleeved garment capable of maintaining the above.

In order to solve the above problems, the present invention provides:
A garment having a cylindrical sleeve having a length exceeding the elbow,
The sleeve includes a heat retaining portion having a heat retention rate of 30 to 50%, and a main body portion having a heat retention rate of less than 30%,
There is provided a garment with a sleeve characterized in that the heat retaining part is provided in an area covering at least the front elbow including the elbow of the wearer.

In order to obtain physiological data, the present inventor measures the body surface temperature of each part of the body including the hand with an infrared thermal image using an infrared radiation thermometer, and monitors the above-mentioned problem of cold hands. Focusing on the subjective responses of the scientists, repeated earnest research experiments.
As a result, it has been found that there are three locations in the upper limbs of the human body and the surrounding area where heat can easily escape: the side, the front elbow, and the wrist.
In the region where the heat easily escapes and the cold occurs, blood vessels flow near the surface of the skin, and these blood vessels are covered with less fat and muscles. Escapes and blood temperature falls. As a result, warm blood does not flow in the peripheral blood vessels in the hand that are continuous with the blood vessels that pass through this region, and cooling occurs.
In particular, among the above-mentioned parts, the side part is the part where heat is most likely to escape, but since it is not opened during normal operation and is covered with clothes, heat is difficult to escape.
Therefore, in order not to let the heat escape, it is conceivable to keep the front elbow and the wrist warm, but when only the wrist is warmed, the blood temperature has already dropped in the front elbow and the peripheral blood vessels Can't send warm blood. In addition, when both the front elbow and wrist are kept warm, there is a problem in that the decrease in blood temperature is small and the hand becomes too hot.
From the above results, by keeping the front elbow between the side and wrist warm, the blood vessels that pass through this part can be warmed, and warm blood can be sent to the peripheral peripheral blood vessels of the hand, eliminating the coldness of the hand The present invention has been achieved by finding that the position is most suitable for the purpose.

  The front elbow is a position indicated by B on the front surface of the upper limb shown in FIG. 1 and corresponds to the front surface of the elbow. A is an elbow fossa which is a hollow part of the whole elbow joint part. C is the forearm, D is the forearm, and E is the ridge. On the rear surface of the upper limb, F is the elbow point, G is the rear elbow, H is the rear upper arm, and I is the rear forearm. The elbow point F is also called the elbow head, and is located approximately on the back side of the elbow fossa A.

  Furthermore, in order to examine the clothing that can efficiently warm the hand, the present inventor determines how much of the region including the front elbow B should be the heat retention range, and the fabric required in that case. The thermal insulation rate was verified from a physiological evaluation and the subjective viewpoint of the wearer.

  Specifically, monitors (six persons who have experienced underwear evaluation and who can answer with reproducibility and unbiased answers) wear long-sleeved underwear, and the samples shown in (A) to (H) of Table 1 Evaluation was performed by applying application cloths sequentially.

First, in order to obtain physiological data, the temperature of the hand (palm) of the upper limb is displayed on an infrared thermal imaging apparatus (TVS-600 series) using a NEC thermo-tracer (infrared radiation thermometer TH3100MR). Measurements were made to see if there was a difference in the degree of hand temperature drop when a patch was applied to the relevant part.
Among the six evaluators, the case where there were 4 or more persons with a small degree of temperature drop on the hand was evaluated as “◯”, the case of 3 persons as “Δ”, and the case of 2 persons or less as “x”.

In addition, in order to obtain data on the subjective evaluation of the wearer, the warmth of the hands when applying the application cloths in sequence and the warmth of the trunk were reported. The “trunk” refers to a part of the human body excluding limbs (upper limbs and lower limbs).
In the subjective evaluation, among the 6 monitors, the evaluation was evaluated as “◯” when 4 or more people felt comfortable and warm, “△” when 3 people, and “×” when 2 or less people. In addition, when it was too hot and felt uncomfortable, it was set as "x".

From the results of the physiological evaluation and subjective evaluation,
A case where there are two or more ○ and there is no × is “○”,
“△” indicates a case where there is only one ○ and no ×
“×” means that there are one or more ×
A comprehensive evaluation was conducted.
The results are as shown in Table 1.

  As shown in Table 1, it was samples (C) and (D) in Table 1 that felt warmth in the trunk as well as the hands, and the overall evaluation was “◯” or “Δ”.

From the physiological evaluation by the thermotracer described above and the subjective evaluation by the monitor, it is preferable to warm the anterior elbow including the elbow and the part mainly covering the downward direction from the elbow, and conversely, the wrist and the elbow It was found that when both were warmed, it would become too thick to control the body temperature.
From the viewpoint described above, it has been found that an underwear that has been warmed as a whole as provided conventionally is not effective in warming a specific hand while maintaining the wearer's comfort.

  As a result of the above-described research experiment, in the present invention, the region of the front elbow including at least the elbow fossa is used as the heat retaining portion, and the heat retaining rate of the clothing covering the region is higher than that of the main body. Further, when the sleeve length is the length that reaches the wrist, the heat retaining portion is not provided in the wrist.

According to the garment with a sleeve of the present invention, the region covering the front elbow including the elbow is locally kept warm, and heat dissipation from the blood flowing through the blood vessel located in this region is suppressed. The temperature of the blood flowing in the peripheral blood vessels is not lowered, and the occurrence of cold hands is prevented. Moreover, since the site | part to heat-retain is local, the excess heat | fever of a trunk can be radiated | emitted from another site | part, and a trunk does not become too hot. Thereby, the temperature of the trunk can be naturally adjusted to an appropriate temperature at which deep sleep can be obtained while appropriately maintaining the body temperature regulation function of the human body.
In this way, by increasing the heat retention rate in the vicinity of the front elbow, it is possible to provide clothes such as underwear that can eliminate the coldness of the hand without increasing the heat retention rate of other portions. Accordingly, even in winter, one hand can sufficiently warm the hand, and an appropriate trunk temperature can be obtained. Therefore, it is not necessary to thicken or raise the material of the entire garment, it can be made comfortable without feeling hot, and swelling can be prevented.

The heat retention rate of the heat retaining unit is 30 to 50%, preferably 32 to 43%.
The heat retention rate of the heat retaining part is set to 30 to 50%. If it is less than 30%, the effect of warming the hand cannot be sufficiently obtained, and if it exceeds 50%, heat is accumulated due to an excessive heat retaining effect, resulting in an uncomfortable feeling. This is because there is a tendency to feel and it is difficult to obtain comfort when worn.

The main body has a heat retention rate of less than 30%, preferably 16 to 28%, particularly preferably 18 to 25%.
The reason why the heat retention rate of the main body portion is less than 30% is that if the heat retention rate of the main body portion is 30% or more, the material of the entire garment becomes thick, feels hot, and comfortable deep sleep cannot be obtained.

In addition, a heat retention rate (%) can be calculated | required as follows using a heat retention tester.
That is, the constant temperature heat source is covered with a sample fabric, adjusted so that the temperature of the constant temperature heat source becomes 30 ° C., and the amount of heat radiated from the heat source toward the low temperature outside air (20 ° C.) becomes constant, and the heat source The amount of heat radiation W [J / cm ² · s] from the heat source body after 10 minutes has elapsed after the surface temperature of the steel sheet shows a constant value. On the other hand, the heat radiation amount W0 [J / cm ² · s] from the heat source is measured in the same manner as described above without covering the heat source body with the sample fabric. By substituting these values into the following formula (1), the heat retention rate from the sample fabric is obtained. As the heat retention tester, for example, “KES-F7 Thermolab 2” manufactured by Kato Tech Co., Ltd. can be used.
Thermal insulation rate (%) = (1−W / W0) × 100 (1)

It is preferable that the heat retaining portion is provided in a range from a position 3 to 7 cm above the elbow fossa to a position 12 to 18 cm below.
The range corresponds approximately to the range from 4 to 5 quarter sleeves to 8 part to 9 quarter sleeves. In particular, it is more preferable to provide in the range from the 5th sleeve to the 8th sleeve.
If the range of the heat retaining portion is set to the smaller range, the area of the portion for increasing the heat retention rate becomes too small, and the desired effect due to the partial increase of the heat retention rate is not obtained. On the other hand, if the heat retaining part is larger than the above range, the wrist part may be covered, it becomes too hot, body temperature adjustment becomes difficult, and the wearer's feeling of wear may be impaired.

  The heat retaining part needs to be provided in the sleeve front region including at least the front elbow, but it is more preferable to cover the sleeve including the sleeve rear region in consideration of a shift caused by the wearer's movement. .

The heat-retaining part is made higher than the heat-retaining rate of the main body part by attaching a patch to the inner surface or the outer surface of the main body part, printing the resin on the main body part, raising the main body part, and changing the knitting structure. It is preferable.
Specifically, the means listed below are used alone as means for increasing the heat retention rate. Or, in combination, the heat retention rate of the heat retention portion is increased more than the heat retention rate of the main body portion.
・ Sew a patch with a high heat retention rate on the body cloth.
-A material having a high heat retention rate is used instead of the material of the other main body portion, and the material having a high heat retention rate is stitched together with the material of the main body portion at the boundary line.
-Change the knitting structure to the rib or bag with the same material. Alternatively, when the bag is knitted, the portion has a double structure having a hollow portion, so that the heat retention rate can be increased.
・ Make the knitting density dense without changing the knitting structure with the same material.
・ Apply additional thread (cut boss) with the same material. The above-mentioned additional yarn is obtained by adding yarn to a necessary portion in circular knitting, and the portion where the yarn is added has more yarn than other portions, so that the heat retention rate can be increased.
・ Welding materials such as resin.

  Among the means for increasing the heat retention rate, the most preferable is a means for sewing a laying cloth having a high heat retention rate cut into a required shape on a cloth forming another main body portion. As the kind of the covering cloth, an appropriate cloth is selected according to the combination with the cloth of the main body part, and either the same material as the main body part or a different material from the main body part may be used. When different materials are used, it is possible to freely provide various heat retention rate differences by using materials having different heat retention rates as the application cloth. In addition, an air layer is formed between the application cloth and the main body, and the heat retention rate can be further increased by the generation of the air layer.

  The application cloth may be sewn on the skin side of the main body, or may be sewn on the opposite outer side. When sewing on the skin side, the patch will touch the skin directly, which is preferable in terms of warmth, especially when the patch is a material with a higher heat retention rate than the body material. Can be made. On the other hand, when the patch is sewn to the outside of the main body, only the material of the main body touches the skin side, there is no step on the surface that touches the skin, and there is a feeling that the sewing site touches the skin and tingles. Since it disappears, it is excellent in terms of wearing.

  When the heat insulation part is provided by changing the material of the other part (main body part), the material of the heat insulation part and the material of the other part are sewn and integrated, and there is no step on the clothing itself, and the thickness Therefore, there is an advantage in appearance. In the case where the heat retaining part is provided with the same material as that of the main body part and the knitting density is changed, since there are no steps or stitches in the garment, there is an advantage that the feeling of wearing is improved. Further, when a heat retaining material is provided by welding a heat retaining material such as a resin to the main body, there is an advantage that the heat retaining rate can be easily controlled.

  It is preferable that the heat retention rate of the heat retaining portion is 1.5 times or more and 2.2 times or less the heat retention rate of the other main body portion. The ratio of the heat retention rate varies depending on the heat retention rate of the material of the main body, the heat retention rate of the application cloth, and the like, and varies depending on the use of the clothing itself and the wearer's preference. For example, when the overall body warmth is required for winter underwear, etc., the body is made of a material with a relatively high thermal insulation rate, and the thermal insulation rate of the thermal insulation part in the area covering the front elbow is Although it is higher than the main body, the difference (ratio) in the heat retention is small. On the other hand, in sleeping underwear or the like, when the main body portion is formed of a material having a low heat retention rate and the heat retention portion is made of a material having a high heat retention rate, the difference in heat retention rate is relatively large.

  The reason why it is 1.5 times or more as described above is that when it is less than 1.5 times, no difference in the heat retention rate from other parts was found in either subjective data or physiological data. On the other hand, 2.2 times or less is that if the ratio of the heat retention rate with the main body is too large, 2.2 times or more, the feeling of wearing becomes worse and physiologically unfavorable, and actual production is also difficult. Because it is.

  Even within the region of the heat retaining portion, the heat retention rate may be different, or the heat retention rate may be constant within the region of one part. Specifically, when the heat insulation part is provided in a large area, the heat insulation rate can be changed by changing the knitting density or knitting structure or changing the thickness of the material according to the degree of need for warmth. Is preferred.

  The material that can be used for the main body is not particularly limited as long as the material has a heat retention rate of less than 30% as described above, and examples thereof include cotton, nylon, rayon, silk, and wool. Among these, natural materials such as cotton are preferable from the viewpoint of preventing a feeling of tightening at the time of wearing and a feeling of wearing at the time of sleeping.

  The portion that needs to be warmed is heated efficiently by increasing the heat retention rate, and the other main body portions are portions that do not need to be warmed so much, so there is no problem even if the heat retention rate is low and the material is thin. Therefore, the clothing can be made thin overall, and swelling and the like can be prevented. Further, the main body portion is preferably made of a material having a high heat retention rate in clothing for winter, although the heat retention rate is lower than that of the heat retention portion.

In addition, parts that do not need to be warmed, such as the body part of the main body, may be formed of a material having high air permeability or a material having good sweat absorption. Furthermore, since it is a site | part which does not need to warm also about sleeve parts other than the said heat retention part, you may form with a raw material with a small heat retention rate.
In addition, if the chest, armpit, and arm contact parts that do not need to be warmed are made air-permeable or sweat-absorbing so as not to accumulate heat, a comfortable underwear can be obtained.

  The garment of the present invention is particularly suitably used as an undergarment including an undershirt with sleeves and lingerie. The clothing of the present invention can be applied not only to underwear, but also to outerwear such as skis, outerwear such as T-shirts, shirts, blouses, and trainers.

  As described above, according to the present invention, the hand can be kept warm, while the heat retention effect on the trunk can be sufficiently prevented and the wearer's comfort is maintained. can do.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The following first, second, and third embodiments are women's underwear shirts, and increase the heat retention rate of the required part by attaching a cloth to the heat retaining area including the front elbow of the sleeve, especially during sleep It is suitable as an underwear for children.

The underwear shirt 10 for women of 1st Embodiment is shown in FIG.
FIG. 2A is a front perspective view of the underwear shirt 10 of the present embodiment, and FIG. 2B is a rear perspective view.
The underwear shirt 10 extends to the abdomen or waist and has an eight-quarter sleeve, the neck is a round neck with a shallow neck, and comprises a front body 11, a back body 12, and left and right sleeves 13, 14, 12 is sewn on the left and right side lines, and these front and rear bodies 11 and 12 and sleeves 13 and 14 are sewn on the shoulders.
The front body 11 and the back body 12 may be formed from an integral cloth, and the shape of the main body is not limited.

  The main body portion 15 including the front and rear bodies 11 and 12 and the sleeves 13 and 14 is formed of a cloth made of spandex-containing torphan cotton. This torphan cotton is a material that is made of cotton for a long time and has a soft texture and gloss. The main body fabric of this embodiment formed of the torphan cotton has a heat retention rate of 20%. The heat retention rate is measured by the method described above.

The sleeves 13 and 14 are provided with a heat retaining part 17 by overlapping and sewing a covering cloth 16 on the back side (skin side) of the main body cloth 15 in a region covering the front elbow part including the elbow fossa A. The mounting position of the patch 16 is from a position 5 cm above the elbow fossa A to a position 15 cm below, and from the position of approximately 4 to 5 quarter sleeves to the tip position of the eighth quarter sleeves, that is, from the sleeve hems 13 a and 14 a. Yes.
Within the said range, the said patch 16 is located in the perimeter part of a sleeve part, and has covered the elbow part as shown to FIG. 2 (B).

  In the present embodiment, a cloth made of well thermostat is used as the application cloth 16. Welthermo is a raised material using acrylate fiber "X (registered trademark)". It is a fabric that has a warm, moisture-like absorbency like cotton, and has the ability to respond to changes in humidity and temperature. It is excellent in dealing with environments and environments with large temperature changes. The heat retention rate of the patch 16 is 27%, which is higher than that of the main body 15. In addition, the heat retention rate of the patch attachment part (the heat retaining portion 17) in which the spandex-filled Turfan cotton of the main body portion 15 and the well thermostat of the patch fabric 16 are overlapped is 32%, and the main body portion consisting only of spandex-filled Turfan cotton It is about 1.6 times 15.

  The shape of the patch 16 is cut into a rectangular shape with one side being 20 cm and the other side being a circumference around the tube of the sleeve, and the patch 16 having this shape is sewn to the back surface of the main body 15. ing. Correspondingly, the cloth 16 may be sewn and integrated when the sleeves 13 and 14 are sewn, or may be sewn and integrated after all the main body portions 15 are sewn. Thus, the cloth 16 is located in a region covering the front elbow part that requires warmth, and only the part that needs warmth is attached to the cloth 16 to increase the heat retention rate, thereby keeping the heat retaining part 17. Is forming.

In the garment with sleeves of the first embodiment of the present invention, since the main body 15 is also formed of a fabric having a relatively high heat retention rate, it is suitably used as a mid-winter sleeping underwear. In addition, the warmth of the area covering the wearer's front elbow is increased so that the hands that are likely to feel the cold are warmed. Can be given.
Furthermore, the shirt of the present embodiment has an eight-quarter sleeve, and since the heat retaining part does not extend to the wrist, the blood vessel is not excessively warmed, and the wearer does not feel uncomfortable.

In the type in which the heat retention rate is the highest in the first embodiment, as the material of the main body portion 15, a material made of reversible milling, cashmere, and cotton bag knitting is suitably used. Other heat retaining materials other than well thermo, such as Outlast (registered trademark), can be used.
In addition, two sheets may be stacked using the same material as the main body 15 or reversible milling bag knitting may be used.
However, it is essential that the heat retention rate of the main body portion 15 is less than 30%, and the heat retention rate of the heat retention portion 17 composed of the main body portion 15 and the batter 16 is in the range of 30 to 50%.

FIG. 3 shows a first modification of the first embodiment, in which only the attachment position of the application cloth in the first embodiment is changed.
Specifically, as shown in FIG. 3 (A), the heat retaining portion 17 is provided with the attachment position of the patch cloth 16 being set at a position 12 cm below the position 5.0 cm above the elbow fossa A of the wearer. The position of the heat retaining portion 17 corresponds to the position of the fourth to fifth quarter sleeves to the seventh to eighth quarter sleeves. In this modified example, the portion from 12 cm below the elbow fossa A to the sleeve hems 13a and 14a is made of the same cloth as the main body cloth 15, and the patch cloth 16 is not provided.
The patch 16 is located on the entire circumference of the sleeve and covers the elbow as shown in FIG.
In this way, by providing the patch 16 on the entire circumference, the patch 16 can reliably cover the wearer's front elbow, so that the effect can be maintained even if the wearer moves.

FIG. 4 shows a second modification of the first embodiment, in which only the attachment position of the patch is changed from that of the first modification.
As shown in FIG. 4A, the front view is the same as that of the first modification, but as shown in the rear view shown in FIG. It is attached without being placed at the position corresponding to the elbow.
In the present modification, the main body cloth 15 and the application cloth 16 are the same as those in the first modification.

5A and 5B show a women's shirt 20 of the second embodiment, which has a round neck like the women's shirt 10 of the first embodiment, but has a deep collar and long sleeves 23 and 24. It is said.
The body parts 25 of the front and rear bodies 21, 22 and the sleeves 23, 24 are made of spandex cotton with spandex having a heat retention rate of 20%, as in the first embodiment. On the other hand, a heat-retaining part 27 is provided by sewing a patch cloth 26 at a position 15 cm below the position 5 cm above the elbow fossa A of the sleeves 23 and 24. The patch cloth 26 is not sewn from the position 15 cm below the elbow socket A to the sleeve hems 23 a and 23 b, and the same cloth as the main body cloth 25 is used. That is, the ladies' shirt 20 of the second embodiment has long sleeves, and the sleeves 23 and 24 made of the main body cloth 25 extend to the wrist, but the heat retaining portion does not extend to the wrist.
As the patch 26, a well thermo fabric having a heat retention rate of 27% is used, and the patch 16 of the first embodiment is overlapped. The part where the cloth 26 is attached to the main body part 25 (the heat retaining part 27) has a heat retention rate of 43%, which is 2.2 times the heat retention rate of other parts.

  The women's shirt 20 of the present embodiment has a deeper neckline than the women's shirt 10 of the first embodiment, has a long sleeve, and uses two pieces of well-thermo fabric as a cover, further increasing the heat retention rate. Therefore, it can cope with colder environments.

  In the case of a moderate heat retention rate in the second embodiment, modal and spandex-containing torphan cotton are also preferably used as the material of the main body portion 25, and the same material as that of the main body portion 25 is used as the application cloth 26. May be used in a stacked manner, or a wool sheet, modal bear milling, fleece or the like is preferably used.

  Moreover, when it is not desired to keep the heat retention rate of the main body portion of the second embodiment so high, cotton milling, Chinon smooth, nylon mesh, or the like is also preferably used as the main body material. As the application cloth 26, two sheets may be stacked using the same material as the above-mentioned main body part, or a modal bear milling machine, a fleece or the like is also preferably used.

  FIGS. 6A and 6B show a third embodiment, in which the heat retention rate is made different by changing the density of the stitches without attaching a patch. That is, the shirt shown in FIG. 6 (A) has the same shape as the shirt of the first embodiment, but the main body portion 15 'is formed from a knitted fabric of the front tactel back esque molding, and the application cloth is applied in the first embodiment. By changing the knitting structure without attaching a patch to the part that was attached, the density of the stitches was made denser than other parts, and the heat retention rate was about 1.5 times higher than other parts. A heat retaining part 17 'is provided. In this embodiment, the heat retaining portion 17 'is pile knitted with a heat retention rate of 32.6%, and the other portions are float knitted with a heat retention rate of 21.4%.

In addition, while changing the knitting structure, the main body portion 15 ′ may be knitted with a front cermaster back cotton, while the heat retaining portion 17 ′ may be pile knitted with the same front ceramat back cotton as the main body portion. The table Cermastat is a yarn knitted with hollow polyester yarn and hollow cotton yarn.
Further, instead of changing the heat retention rate depending on the density of the stitches, the yarn may be changed. In other words, the heat retaining portion where the heat retention rate is desired to be increased may be knitted using yarns that are thicker than the yarns of other parts or yarns that are raised, so that the heat retention rate is different.
Furthermore, a heat insulating material made of polyurethane resin can be welded to the heat retaining portion that increases the heat retention rate. In that case, the resin is not limited to polyurethane, and polyethylene, polyester, and the like can also be used.

(Example)
The following experiment was conducted on the clothes with sleeves of the first embodiment of the present invention.
Fig. 2 (A) type shirt with 8/4 sleeves When fabric with a heat retention rate of 32% is used for the heat retaining section 17, type A and B type underwear using a fabric with a heat retention rate of 28% are prepared and heat retention Evaluation was performed based on the difference from general-purpose underwear (hereinafter referred to as “control”) composed of long sleeves of the same shape without the portion 17.

Details of each sample are as follows.
A-type underwear: body part = Turfan cotton, knitting with a tengu (heat retention 20%)
Heat insulation part = Welding one sheet of well thermo to the body part fabric (heat retention rate 32%)
B-type underwear: main body = turf cotton knitting (heat retention 20%)
Insulation section = 1 outlast (registered trademark) only (Insulation rate 28%)
Control: Main body = Turfan cotton knitting with tempura (heat retention 20%)
Thermal insulation part = none

The above-mentioned A type, B type, and control underwear were worn by six monitors, and “warmth of the hand”, “warmth of the trunk”, and “total comfort” were investigated as subjectivity evaluation.
In addition, physiological evaluation was performed using a thermographic apparatus.

As a result, as a subjective evaluation, there were 6 people who said that “warmth of the hand” was warmer than the control underwear, and 5 people said that the B type was warmer than the control underwear. In “Warmness of the trunk”, 5 people said that the A type underwear was warmer than the control underwear, and 5 people said that the B type was warmer than the control underwear. .
Regarding “total comfort”, there were 6 people who were comfortable with A type underwear and 5 people who were comfortable with B type.
Physiological evaluation with a thermographic device showed that 3 people showed an increase in body surface temperature when wearing A type underwear than control underwear, and 1 people considered B type warmer than control underwear. In many cases, the hands became warm when wearing underwear with a heat retention rate of 32%.

  From the results of the experiment using the monitor, it was confirmed that the garment with sleeves of the present invention was an excellent underwear in terms of total comfort without warming the hands and lowering the temperature of the trunk.

It is a figure which shows the upper limb division of a human body, the figure left side shows the front surface of an upper limb, and the figure right side shows the rear surface of an upper limb.
