The present invention provides clothing which can keep the internal environment of clothing comfortable, has excellent wearing comfort and wearing feeling, and can be suitable for various wearing scenes requiring comfort, such as high-temperature and/or high-humidity environment, offices, families, etc., by suppressing the stuffiness feeling and the summer heat feeling in the clothing.
Description
Technical Field
The present invention relates to clothing excellent in wearing comfort and wearing feeling.
Background
As measures against global warming, increasing the set temperature of an air conditioner in summer and decreasing the set temperature of the air conditioner in winter to reduce the air conditioning load are one of effective measures to reduce the amount of carbon dioxide emissions. For example, in winter, it is possible to cope with a case where the air conditioning set temperature is lowered by increasing the amount of clothes to be worn, and by wearing clothes made of a winter warm-keeping material having excellent heat absorption and warmth retention properties. On the other hand, in summer, there is a limit to the reduction of the amount of clothing in social life, and thus, various proposals have been made for comfortable materials and clothing suitable for summer.
Documents of the prior art
Patent document
For example, patent document 1 proposes a woven fabric including a composite yarn having 2 types of yarns with different yarn length changes between drying and water absorption and moisture absorption, and having a change in air permeability according to the humidity in the clothing. According to the scheme, when the humidity in the clothes is high, the fibers absorb moisture and extend, so that the air permeability is improved; when the humidity in the clothes is low, the fibers are contracted by moisture removal, and therefore, the air permeability is reduced, thereby making it possible to maintain the environment in the clothes comfortable.
In addition, patent document 2 proposes a garment (so-called air-conditioning garment) in which a blower fan is attached to a fabric having low air permeability. In this scheme, the cool feeling is obtained by sending the outside air into the clothes through the blowing fans installed at both sides of the waist on the back of the human body.

Patent document 2: international publication No. 2017/006481
Disclosure of Invention
Problems to be solved by the invention
In the method described in patent document 1, specifically, since a cellulose fiber having moisture absorption is used, there is a small effect of reducing the stuffy feeling in the clothing, and since the air permeability is improved when the humidity in the clothing is high, there is a small effect of reducing the hot feeling in the clothing, but none of these effects is large, and the effect of fundamentally improving the comfort cannot be obtained.
The clothing described in patent document 2 is effective for preventing heatstroke in a wearing scene such as an outdoor construction site in summer and an indoor space in a factory where air conditioning is not effective. However, since the fabric is made of a low air permeability fabric and the clothes are greatly swollen by the outside air fed into the clothes via the blower fan, it is not suitable for wearing scenes such as offices and homes. Further, the blower fan is large in size, so that the feeling of weight and discomfort when worn is strong; since the air permeability of the fabric is low, it is necessary to increase the air volume in order to reduce the stuffiness feeling and the sunstroke feeling in the clothes, and as a result, the sound emitted from the blower fan becomes loud, which is a big reason why the fabric is not suitable for wearing scenes such as offices and homes.
The present invention has been made to solve the above problems of the prior art, and an object of the present invention is to provide clothing which can keep the internal environment of clothing comfortable, has excellent wearing comfort, and has excellent wearing feeling, while suppressing stuffiness and hotness in the clothing.
Means for solving the problems
In order to solve the above problem, the clothing of the present invention has the following configuration. That is to say that the first and second electrodes,
a garment comprising a fabric at least partially using hygroscopic fibers, the fabric having an air permeability of 50 to 500cm3/cm2And s, the clothes are provided with a power supply unit and a blowing fan unit with the outer diameter of less than 80 mm.
The clothes of the present invention preferably include a blower fan unit having an outer diameter of 30mm or less.
In addition, the clothes of the present invention are preferably provided with the blower fan unit at 1 or more locations selected from the group consisting of near the neck opening, near the cuff, and near the hem opening, and inside the clothes.
Further, the garment of the present invention preferably has a difference in moisture absorption rate (Δ MR) of the moisture-absorbent fibers of 2.0 to 10.0%.
Effects of the invention
According to the present invention, since it is possible to provide clothing in which stuffiness and summer heat feeling in the clothing are suppressed, the internal environment of the clothing can be kept comfortable, and the clothing is excellent in wearing comfort and wearing feeling, it is possible to adapt to various wearing scenes requiring comfort such as high-temperature and/or high-humidity environments, offices, and homes.
Detailed Description
The clothing of the invention comprises a fabric at least partially made of hygroscopic fibers, the fabric having an air permeability of 50 to E500cm3/cm2And s, the clothes are provided with a power supply unit and a blowing fan unit with the outer diameter of less than 30 mm.
The sensible temperature is a parameter for quantifying the sensation of temperature felt by human skin, and is an important index in consideration of wearing comfort of clothes. There have been many studies on factors affecting a sensible temperature and a formula of the sensible temperature, and among them, the following formula (1) which represents the sensible temperature using air temperature, relative humidity, and wind speed as variables proposed by Gregorczuk is widely used at present because of its wide application range.
[ mathematical formula 1]
NET (. degree. C.): sensible temperature (NET NET effective temperature)
T (. degree. C.): air temperature
H (%): relative humidity
v (m/s): wind speed
Here, according to the above equation (1), in a high temperature and/or high humidity environment such as outdoors in summer and indoors where air conditioning is not effective, it is effective to reduce the temperature and relative humidity and increase the wind speed in order to reduce the sensible temperature and improve the wearing comfort.
The present invention will be described in detail below.
The clothing of the present invention includes a fabric using at least partially hygroscopic fibers, and specific examples of the hygroscopic fibers include, but are not limited to, polyester-based hygroscopic fibers, polyamide-based fibers, polyacrylonitrile-based fibers, rayon-based fibers, acetate-based fibers, cotton, hemp, silk, wool, and the like. Among them, polyester-based hygroscopic fibers and polyamide-based fibers are preferable because they are excellent in mechanical properties and durability.
In the present invention, the difference in moisture absorption rate (Δ MR) of the moisture-absorbent fiber is preferably 2.0 to 10.0%. The difference in moisture absorption rate (Δ MR) of the moisture-absorbent fibers in the present invention is a value measured by the method described in examples. The Δ MR is a difference between a moisture absorption rate at a temperature of 30 ℃ and a humidity of 90% RH, which is the internal temperature and humidity of clothes after slight exercise, and a moisture absorption rate at a temperature of 20 ℃ and a humidity of 65% RH, which is the external temperature and humidity. That is, Δ MR is an index of moisture absorption rate, and the higher the value of Δ MR, the less stuffy and sticky feeling during sweating is reduced, and the wearing comfort of clothes is improved. When the Δ MR of the moisture-absorbent fiber is 2.0% or more, the clothing of the present invention is worn with less stuffy feeling and sticky feeling in the clothing during sweating, and the wearing comfort is preferably improved. The Δ MR of the moisture-absorbent fiber is more preferably 3.0% or more, and still more preferably 4.0% or more. On the other hand, if the Δ MR of the hygroscopic fiber is 10.0% or less, the process passability and the handling property in the production of a fabric or garment are good, and the durability in use is also excellent, which is preferable. The Δ MR of the moisture-absorbent fiber is more preferably 9.0% or less, and still more preferably 8.0% or less.
In the present invention, as a specific example of the polyester-based hygroscopic fiber having Δ MR in the above range, the sea-island type composite fiber described in international publication No. 2018/012318 can be suitably used. The sea-island type composite fiber described in this publication comprises a hydrophobic polyester polymer as a sea component and a hygroscopic polymer as an island component. Therefore, it is preferable to achieve both the moisture absorption by the moisture-absorbing polymer of the island component and the dry feeling by the polyester-based polymer of the sea component, and to obtain clothes which are reduced in stuffy feeling and sticky feeling at the time of sweating and in wet and cool feeling after sweating and are excellent in wearing comfort.
In the present invention, it is also possible to suitably use a hygroscopic fiber obtained by applying a hygroscopic compound to the fiber surface of a hydrophobic fiber or by forming a film of a hygroscopic compound on the fiber surface of a hydrophobic fiber.

In the present invention, the single fiber fineness of the hygroscopic fiber and the other fibers is not particularly limited and may be appropriately selected depending on the application and the required characteristics, but is preferably 0.5 to 4.0 dtex. The single fiber fineness in the present invention is a value obtained by dividing the total fineness by the number of single fibers. When the single fiber fineness is 0.5dtex or more, the yarn breakage is small, the process passability is good, the amount of fluff generated during use is small, and the durability of clothes is excellent, which is preferable. The single fiber fineness is more preferably 0.6dtex or more, and still more preferably 0.8dtex or more. On the other hand, a single fiber fineness of 4.0dtex or less is preferable because the flexibility of the clothing is not impaired.

The clothes of the invention comprises a power supply unit and a blower fan unit with an outer diameter of 80mm or less.
In the present invention, the power supply unit is a component for supplying electric power to the blower fan unit, and is connected to the blower fan unit via a wiring such as a power supply line having connection terminals at both ends (not shown). As the power source in the present invention, a battery such as a primary battery, a secondary battery, or a solar battery may be used, or a commercial power source via a power adapter may be used.
In the present invention, the installation position of the blower fan unit can be appropriately selected according to the form and wearing scene of the clothes, but it is preferable that the blower fan unit is provided at 1 or more locations selected from the group consisting of near the neck opening, near the cuff, and near the hem opening and inside the clothes. In the human body, the skin near the neck, wrist, and ankle is thin, and is a position where the skin is close to blood vessels. Therefore, it is preferable that at least any one of the neck, the wrist, and the ankle is cooled by the air blown from the blower fan unit provided at least any one of the positions near the neck opening, the cuff, and the hem opening inside the clothing, and the cooled blood is circulated throughout the body, so that the sensible temperature can be effectively reduced, the feeling of summer heat can be reduced, and the wearing comfort can be improved. In the present invention, the term "vicinity" of the neck opening, the cuff and the hem opening means a position where the shortest distance from the end of the fabric of the neck opening, the cuff and the hem opening to the blower fan unit is 50mm or less.
In the present invention, the blower fan unit is a constituent part of the blower fan unit having a blower fan therein.
In the present invention, the outer diameter of the blower fan unit is 80mm or less.

Further, unlike the conventionally proposed blower fan unit represented by patent document 2, since the blower fan unit can be made very small, the degree of freedom of the attachment position to the clothing is high, and the clothing can be attached to a narrow position such as a collar, a cuff, or a hem, and the clothing can be designed according to the form and wearing scene of the clothing. The outer diameter of the blower fan is more preferably 25mm or less, still more preferably 20mm or less, particularly preferably 15mm or less, and most preferably 8mm or less.
In the present invention, the thickness of the blower fan unit is preferably 10mm or less. When the thickness of the blower fan unit is 10mm or less, the blower fan unit is preferably smaller than the blower fan unit in the air-conditioning suit proposed in the related art as represented by patent document 2, and therefore, the air-conditioning suit has no sense of weight and discomfort when worn, can greatly improve the feeling of wearing, and can be applied to various wearing scenes requiring comfort, such as offices and homes. Further, unlike the conventionally proposed blower fan unit represented by patent document 2, the blower fan unit is very small, and therefore, the degree of freedom of the attachment position to the clothes is high, and the blower fan unit can be attached to a narrow position such as a neck opening, a cuff opening, or a hem opening, and the clothes can be designed according to the form and wearing scene of the clothes, which is preferable. The thickness of the blower fan unit is more preferably 8mm or less, still more preferably 6mm or less, and particularly preferably 4mm or less.
In the present invention, the weight of the blower fan unit is preferably 5g or less. When the weight of the blower fan unit is 5g or less, the blower fan unit is preferably lighter than the blower fan unit in the air-conditioning suit proposed in the related art as represented by patent document 2, and therefore, the air-conditioning suit has no sense of weight and discomfort when worn, can greatly improve the feeling of wearing, and can be applied to various wearing scenes requiring comfort, such as offices and homes. Further, unlike the conventionally proposed blower fan unit represented by patent document 2, the blower fan unit is very light, and therefore, has a high degree of freedom in the attachment position to the clothing, and can be attached to a narrow width position such as a neck, cuff, or hem, and the clothing can be designed according to the form and wearing scene of the clothing, which is preferable. The weight of the blower fan unit is more preferably 4g or less, still more preferably 3g or less, and particularly preferably 2g or less.
In the clothes of the present invention, the number of the blower fan units is not particularly limited, and the blower fan units can be attached to the clothes within a range that does not impair the wearing feeling, etc., according to the outer diameter and thickness of the blower fan units.
The form of the clothing of the present invention is not particularly limited, and the clothing may be any of an upper garment and a lower garment, the upper garment may be any of a long-sleeved garment and a short-sleeved garment, and the lower garment may be any of a long lower hem and a short lower hem.

The clothes of examples 7 to 9 were suppressed in stuffiness and summer heat sensation in the clothes, and were able to maintain comfortable environment in the clothes, and were excellent in wearing comfort and wearing sensation.
In comparative examples 1 and 2, although the summer heat sensation was reduced by the air blown from the blower fan unit, the air permeability of the fabric was low, and therefore the spread of sweat was low, and a feeling of stuffiness was felt. In comparative example 3, the stuffy feeling, the hot feeling, and the sweat-wet cold feeling were hardly felt because the air permeability of the fabric was high, but the fabric was thin, so the fabric had a feeling of incongruity due to wearing, and the practicability was poor.
Example 10
Clothes were produced in the same manner as in example 3, except that 3 blower fan units were attached to the left and right cuffs of the inner side of the short-sleeved shirt at equal intervals in the circumferential direction in example 3, and then the power supply unit was connected to all the blower fan units using the power supply cord. The evaluation results of the obtained fabric and clothes are shown in table 3.

The evaluation results of the obtained fabric and clothes are shown in table 3.
In comparative example 4, although the summer heat sensation was reduced by the blowing from the blower fan unit, the blower fan unit had a large outer diameter and thickness, and therefore was heavy and uncomfortable to wear, and was not suitable for wearing scenes such as offices and homes.
Comparative example 5
Clothes were made by the same operation as example 3, except that the blower fan unit was not installed in example 3. The evaluation results of the obtained fabric and clothes are shown in table 3.
The clothing used in comparative example 5 was high in air permeability and contained hygroscopic fibers, but was still feeling stuffy, hot, damp, and cold with sweat, and was not comfortable to wear.
Examples 13 to 15
In example 13, clothes were produced in the same manner as in example 3 except that the hygroscopic polyester used in example 3 and the cotton used in example 5 were cross-knitted at a blending ratio shown in table 4 to produce a fabric, in example 14, the hygroscopic polyester used in example 3 and "LYCRA" (registered trademark) T-327C (22dtex) made by Opelontex (corporation) as a polyurethane fiber were cross-knitted at a blending ratio shown in table 4 to produce a fabric, and in example 15, the cotton used in example 5 and the false twist yarn "TETRON" (registered trademark) 84dtex-36f made by toray (corporation) as a polyethylene terephthalate fiber were cross-knitted at a blending ratio shown in table 4 to produce a fabric. The evaluation results of the obtained fabric and clothes are shown in table 4. The clothes of examples 13 to 15 were suppressed in stuffiness and summer heat sensation in the clothes, and were able to maintain comfortable environment in the clothes, and were excellent in wearing comfort and wearing sensation.
