Technical Field

The present invention relates to clothing that can be suitably used in various wearing situations requiring comfort, such as high-temperature and/or high-humidity environments, outdoors, and at home.

Background

With the progress of global warming, the temperature has been increasing year by year, and outdoor and indoor high-temperature and/or high-humidity environments have increased, and various proposals have been made so far for comfortable raw materials and clothes suitable for summer.

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 the woven fabric has air permeability that changes 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 garment including a fabric having low air permeability. In this scheme, external air is introduced into the clothes by the blowing fans installed at both sides of the waist on the back of the human body to obtain a cool feeling.

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 no small effect on suppression of stuffiness feeling in the clothing, and since air permeability is improved when the humidity in the clothing is high, there is also a slight effect on suppression of sunstroke feeling in the clothing, but none of these effects is large, and the effect of fundamentally improving comfort cannot be obtained.

The clothing described in patent document 2 is effective for preventing heatstroke in wearing situations such as outdoor construction sites in summer and indoors where air conditioning is not effective. However, since the clothing uses a fabric having low air permeability and containing fibers having no hygroscopicity, when the outside air is introduced into the clothing by the blower fan, although stuffiness and hotness in the clothing can be suppressed, when the blower fan is not used, or when the blower fan is stopped due to a battery failure or the like, the stuffiness and hotness in the clothing increase, and wearing comfort is impaired.

The present invention has been made to solve the above-described problems of the conventional art, and an object of the present invention is to provide clothing which can suppress the stuffiness and the sunstroke in the clothing and keep the environment in the clothing comfortable regardless of the presence or absence of air blown from a blower fan, and which is excellent in wearing comfort.

Means for solving the problems

The above problem can be solved by a garment comprising a fabric having moisture-absorbing fibers as main constituent fibers, the fabric having an air permeability of 45cm³/cm²And/s or less, and the laundry has at least 1 suction port for introducing external air into the laundry.

The hygroscopic fiber preferably has a difference in moisture absorption (Δ MR) of 2.0 to 10.0%, and the hygroscopic fiber is a polyester-based hygroscopic fiber and/or a polyamide-based hygroscopic fiber.

Further, it is preferable to adopt a mode in which a blowing fan unit for introducing external air into the clothes is provided, the diameter of a circumscribed circle of the suction port being 80mm or less.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, it is possible to provide clothing that can suppress the feeling of stuffiness and feeling of heat in the clothing and maintain the comfortable environment in the clothing regardless of the presence or absence of air blown from the blower fan, and that is excellent in wearing comfort, and therefore can be suitably used in various wearing situations requiring comfort, such as high-temperature and/or high-humidity environments, outdoors, indoors, and the like.

Detailed Description

The clothes of the invention contain a moisture absorbing materialThe fabric mainly comprises sexual fiber, and has air permeability of 45cm³/cm²And the clothes at least have 1 air suction port for introducing external air into the clothes.

The present invention will be described in detail below.

It is important that the garment of the present invention comprises a fabric having hygroscopic fibers as the main constituent fibers. Here, the main constituent fibers mean fibers having a mixing ratio of 50 mass% or more in the fabric. By using the hygroscopic fiber as the main constituent fiber, the moisture can be promoted to be discharged from the inside of the clothing to the outside of the clothing, and the moisture in the vicinity of the portion using the hygroscopic fiber can be reduced, and the stuffiness can be suppressed. Therefore, the stuffiness is suppressed not only when the outside air is introduced into the clothes by the blower fan unit or the like, but also when the outside air is not introduced into the clothes. Thus, the wearing comfort is maintained even when the blower fan unit is stopped due to, for example, a battery power failure or the like when the use of the blower fan unit is stopped. The mixing ratio of the hygroscopic fibers in the fabric is more preferably 70% by mass or more, still more preferably 90% by mass or more, and particularly preferably 95% by mass or more.

Specific examples of the moisture-absorbent fiber in the present invention include, but are not limited to, polyester-based moisture-absorbent fibers, polyamide-based fibers, polyacrylic fibers, rayon-based fibers, acetate-based fibers, cotton, hemp, silk, and wool. Among them, polyester-based hygroscopic fibers and polyamide-based fibers are preferable because they are excellent in mechanical properties and durability. In addition, the polyester-based moisture-absorbing fiber has quick-drying properties. Therefore, it is particularly preferable to reduce the so-called "cold sweat" in which the body temperature is lost and the body feels cold due to wearing of clothes wetted with sweat after sweating. As a method for imparting moisture absorption to the fiber, there is a method of moisture absorption processing in which the fiber is treated with a hydrophilic compound or the like, but if the fiber itself is a moisture-absorbing fiber having moisture absorption as in the present invention, reduction in moisture absorption during use due to wearing, washing, or the like is suppressed, and the durability of the moisture absorption effect is excellent, so that it is preferable.

The difference in moisture absorption rate (Δ MR) of the moisture-absorbent fiber of the present invention 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. Δ MR is a difference between a moisture absorption rate at a temperature of 30 ℃ and a humidity of 90% RH in the clothes after a slight exercise and a moisture absorption rate at a temperature of 20 ℃ and a humidity of 65% RH, which are the humiture of the outside air. That is, Δ MR is an index of moisture absorption, and the higher the value of Δ MR, the less stuffy and sticky feeling during sweating is reduced, and the more comfortable the clothing is to be worn. When the Δ MR of the moisture-absorbent fiber is 2.0% or more, the stuffy feeling and sticky feeling in the clothing during sweating are reduced and the wearing comfort is improved, which is preferable. Further, it is not necessary to say that the outside air is introduced into the clothes by the blower fan unit or the like, but the clothes in which the feeling of heat and stuffiness are suppressed even when the outside air is not introduced into the clothes are preferable because the wearing comfort is maintained even when the blower fan unit is stopped due to, for example, a power failure of the battery or the like when the use of the blower fan unit is stopped. 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.

The fabric of the present invention may be any fabric having hygroscopic fibers as the main constituent fibers, and the hygroscopic fibers may be mixed, blended, interwoven or cross-knitted with other fibers. Specific examples of the other fibers include, but are not limited to, polyester-based fibers, polyamide-based fibers, polyacrylic-based fibers, polyolefin-based fibers, and polyurethane-based fibers having a moisture absorption difference (Δ MR) of less than 2.0%.

The total fineness of the hygroscopic fiber and other fibers used in the clothing of the present invention is not particularly limited, and may be appropriately selected depending on the application and the required characteristics, and is preferably 10 to 500 dtex. When the total fineness is 10dtex or more, the yarn breakage is small, the process passability is good, the generation of fluff during use is small, and the durability of clothes is excellent, and therefore, the total fineness is preferably 10dtex or more. The total fineness is more preferably 30dtex or more, and still more preferably 50dtex or more. On the other hand, a total fineness of 500dtex or less is preferable because the flexibility of the clothing is not impaired. The total fineness is more preferably 400dtex or less, and still more preferably 300dtex or less.

The single fiber fineness of the hygroscopic fiber and other fibers used in the clothing of the present invention 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 refers to 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 generation of fluff 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 single fiber fineness is more preferably 2.0dtex or less, and still more preferably 1.5dtex or less.

The breaking strength of the moisture-absorbent fibers and other fibers used in the clothing of the present invention is not particularly limited, and may be appropriately selected depending on the application and the required properties, but is preferably 2.0 to 5.0cN/dtex from the viewpoint of mechanical properties. A breaking strength of 2.0cN/dtex or more is preferable because generation of fluff is small and durability is excellent when used. The breaking strength is more preferably 2.5cN/dtex or more, and still more preferably 3.0cN/dtex or more. On the other hand, a breaking strength of 5.0cN/dtex or less is preferable because the softness of the clothes is not impaired.

The moisture-absorbing fibers and other fibers used in the clothing of the present invention are not particularly limited, and the elongation at break of the fibers may be appropriately selected depending on the application and the required characteristics, but is preferably 10 to 60% from the viewpoint of durability. When the elongation at break is 10% or more, the wear resistance of the clothes is good, the generation of fluff during use is small, and the durability of the clothes is good, which is preferable. The elongation at break is more preferably 15% or more, and still more preferably 20% or more. On the other hand, if the elongation at break is 60% or less, the dimensional stability of the clothes is good and the durability of the clothes is excellent, which is preferable. The elongation at break is more preferably 55% or less, and still more preferably 50% or less.

The cross-sectional shape of the absorbent fiber and other fibers used in the clothing of the present invention is not particularly limited, and may be appropriately selected depending on the application and the required properties. The cross section may be circular or non-circular. Specific examples of the non-circular cross section include, but are not limited to, a multilobal shape, a polygonal shape, a flat shape, and an oval shape.

For the garment of the present invention, the air permeability of the fabric was 45cm³/cm²The following is important. The air permeability of the fabric in the present invention is a value measured by the method described in examples. If the air permeability of the fabric is 45cm³/cm²The air flow rate is set to be less than or equal to/s, so that the external air introduced into the clothes by the blower fan unit can be prevented from being discharged from the gap between the fabrics, and the external air introduced into the clothes can be efficiently circulated in the clothes. As a result, sweat discharged from the body can be efficiently evaporated in the clothes, and the body can be accelerated to be cooled by the heat of evaporation during evaporation. The air permeability of the fabric is more preferably 40cm³/cm²A concentration of 30cm or less, more preferably³/cm²Less than s, particularly preferably 20cm³/cm²The ratio of the water to the water is less than s. The air permeability of the fabric is preferably 10cm³/cm²More than s. If the air permeability of the fabric is 10cm³/cm²The heat sensation and stuffiness can be suppressed at a temperature of at least s, and therefore, the temperature is preferably controlled. In the clothing of the present invention, the clothing may partially use a fiber structure not having the air permeability and the above-described air permeability, within a range not impairing the object of the present inventionAnd (4) forming the fabric.

The form of the fabric used for the clothing of the present invention is not particularly limited, and woven fabrics, knitted fabrics, napped fabrics, nonwoven fabrics, and the like can be formed by a known method. The fabric of the present invention may be any woven or knitted structure, and plain weave, twill weave, satin weave, double weave, or a modified structure thereof, warp knitting, weft knitting, circular knitting, lace knitting, or a modified structure thereof, and the like may be suitably used.

The fabric used in the garment of the present invention may be dyed as desired. The dyeing method is not particularly limited, and a cheese (cheese) dyeing machine, a liquid flow dyeing machine, a drum dyeing machine, a beam dyeing machine, a Jigger (Jigger), a high-pressure Jigger, and the like can be suitably used according to a known method. In the present invention, the dyeing concentration and the dyeing temperature are not particularly limited, and known methods can be suitably used.

It is important for the laundry of the present invention to have at least 1 suction port for introducing external air into the laundry. Here, the air inlet is not an opening portion such as a collar, a sleeve, or a bottom of a trouser, which is generally provided in the clothing, but a portion which is separately provided to introduce external air into the clothing and has higher air permeability than a basic portion of the clothing. By providing such an air inlet, the outside air can be efficiently taken into the clothing, and therefore, the feeling of summer heat and stuffiness can be suppressed, and the clothing can be worn with excellent wearing comfort. Therefore, not only when the outside air is introduced into the clothes by the blower fan unit or the like, but also when the outside air is not introduced into the clothes, the feeling of sunstroke and stuffiness is suppressed, and the wearing comfort is maintained even when the blower fan unit is stopped due to, for example, a dead battery or the like when the use of the blower fan unit is stopped.

In the clothing of the present invention, the number of the air inlets and the positions of the air inlets are not particularly limited, and can be appropriately selected within a range that does not impair the wearing feeling, the design, and the like. The air heated by the body temperature inside the laundry flows upward inside the laundry due to a so-called chimney effect in which an updraft is generated inside the laundry due to a decrease in specific gravity. Therefore, the position of the air inlet for introducing the outside air into the clothes is preferably in the vicinity of the lower back surface such as the waist and the side abdomen.

The air inlet provided in the garment of the present invention is preferably made of a material having a higher air permeability than the material of the basic portion (garment main body) constituting the garment from which the air inlet is cut out. By making the air permeability of the air inlet higher than that of the fabric of the clothes main body, the external air can be efficiently introduced into the clothes. From the viewpoint of design, it is preferable that the fabric is made of a material having higher air permeability than the fabric of the basic portion (garment main body) constituting the garment. Further, the air permeability of the air inlet is not particularly limited, but is 200cm³/cm²A temperature of at least s is preferable because the external air can be efficiently introduced into the clothing, and the feeling of summer heat and stuffiness can be suppressed. The air permeability of the suction port is more preferably 300cm³/cm²At least s, more preferably 400cm³/cm²More than s.

The diameter of the circumscribed circle of the air inlet provided in the clothing of the present invention is preferably 80mm or less. The shape of the air inlet is not necessarily limited to a perfect circle, and therefore, in the case where the air inlet is not a perfect circle, the diameter of the circumscribed circle is taken as the size of the air inlet. If the diameter of the circumscribed circle of the air inlet is 80mm or less, the outside air can be efficiently introduced into the clothing without impairing the design property, and the clothing is preferable because it is excellent in wearing comfort. The diameter of the circumscribed circle of the air inlet is more preferably 70mm or less, still more preferably 60mm or less, and particularly preferably 50mm or less. The diameter of the circumscribed circle of the air inlet is preferably 10mm or more. If the diameter of the circumscribed circle of the air inlet is 10mm or more, the external air can be introduced into the clothing, and the feeling of summer heat and stuffiness can be suppressed, which is preferable.

The air inlet provided in the clothing of the present invention is preferably a fastener type ventilation mechanism. If the air inlet has a fastener type ventilation mechanism, the fastener can be opened and closed according to the feeling of summer heat and the feeling of cold when the garment is worn, and the environment in the garment can be adjusted to maintain comfort.

The laundry of the present invention may also have an air outlet for discharging air inside the laundry to the outside of the laundry. The air outlet is not an opening portion such as a collar, a sleeve, or a bottom of a trouser which is generally provided in the clothing, but a portion which is separately provided corresponding to the air inlet and has a higher air permeability than the basic portion of the clothing for discharging the air in the clothing to the outside of the clothing. The provision of such an exhaust port is preferable because ventilation in the clothing can be promoted, and therefore, the feeling of summer heat and stuffiness can be suppressed, and the clothing is excellent in wearing comfort. Therefore, it is preferable that the outside air is introduced into the clothes by the blower fan unit or the like, not to mention that the clothes are prevented from suffering from the feeling of sunstroke and stuffiness, and that the wearing comfort is maintained even when the blower fan unit is stopped due to, for example, a power failure of the battery or the like when the use of the blower fan unit is stopped. In addition, in the case where the air outlet is not provided, when outside air is introduced into the clothes by the blower fan unit or the like, air is discharged to the outside of the clothes from the opening portions of the collar, the sleeves, the bottom of the pants, and the like, and thus the clothes have a swollen shape, which leads to a reduction in the wearing feeling and the design. However, in the case of having the air outlet, the swelling of the clothes as described above can be suppressed, and the clothes have excellent wearing feeling and design, and therefore, the air outlet is preferable.

In the clothing of the present invention, the number of the exhaust ports and the positions of the exhaust ports are not particularly limited, and can be appropriately selected within a range that does not impair the wearing feeling, the design, and the like. As described above, since the air warmed by the body temperature inside the clothes flows upward inside the clothes due to the chimney effect, the position of the exhaust port for exhausting the air inside the clothes to the outside of the clothes is preferably in the vicinity of the upper portion of the back such as the armpit, the back of the neck, or the like. Alternatively, a region where a human body easily feels cold, that is, a region near a region where the density of cold spots is high, or the like may be preferably used. The parts with high cold spot density include, but are not limited to, the shoulder blade, the back, and the waist.

The vent provided in the clothing of the present invention is preferably formed by cutting out the fabric of the portion or by forming the fabric of the basic portion (clothing main body) of the clothingThe material with higher air permeability. By making the air permeability of the air outlet higher than that of the fabric of the clothes main body, the air in the clothes can be efficiently discharged to the outside of the clothes. From the viewpoint of design, it is preferable that the fabric is made of a material having higher air permeability than the fabric of the basic portion (garment main body) constituting the garment. Further, the air permeability of the vent is not particularly limited, but 200cm³/cm²A temperature of the air-permeable layer is preferably higher than s because the air in the clothes can be efficiently discharged to the outside of the clothes, and the feeling of summer heat and stuffiness can be suppressed. The air permeability of the vent is more preferably 300cm³/cm²At least s, more preferably 400cm³/cm²More than s.

The diameter of the circumscribed circle of the exhaust port provided in the clothing of the present invention is preferably 80mm or less. The shape of the exhaust port is not necessarily limited to a perfect circle, and therefore, in the case where the exhaust port is not a perfect circle, the diameter of the circumscribed circle is taken as the size of the exhaust port. If the diameter of the circumscribed circle of the exhaust port is 80mm or less, the air in the clothing can be efficiently exhausted to the outside of the clothing without impairing the design property, and the clothing is preferable because the clothing is excellent in wearing comfort. The diameter of the circumscribed circle of the exhaust port is more preferably 70mm or less, still more preferably 60mm or less, and particularly preferably 50mm or less. The diameter of the circumscribed circle of the exhaust port is preferably 10mm or more. It is preferable that the diameter of the circumscribed circle of the exhaust port is 10mm or more because the air in the clothes can be exhausted to the outside of the clothes, and the feeling of summer heat and stuffiness can be suppressed.

The vent provided in the clothing of the present invention preferably uses a fastener type ventilation mechanism. If the exhaust port has a fastener type ventilation mechanism, it is preferable that the fastener is opened and closed according to the feeling of summer heat and the feeling of cold when the garment is worn, and the internal environment of the garment is adjusted to maintain the internal environment of the garment comfortable.

In the case where the clothes of the present invention includes both the air inlet and the air outlet and includes a blower fan unit described later, a person present at a position close to the blower fan unit is referred to as the air inlet, and a person present at a position distant from the blower fan unit is referred to as the air outlet. In the case where the clothes of the present invention includes both the air inlet and the air outlet and does not include the blower fan unit, the air heated by the body temperature in the clothes flows upward in the clothes due to the chimney effect as described above, and therefore, the air inlet is defined as one existing at a lower position of the clothes and the air outlet is defined as one existing at a higher position of the clothes.

The laundry of the present invention is preferably provided with a blower fan unit for introducing external air into the laundry. Here, the blower fan unit means a unit composed of at least a fan and a motor. By introducing the outside air between the clothes and the body by the blower fan unit, the air accumulated in the clothes can be discharged from the air outlet or the opening such as the collar or the sleeve, and thus the body can be cooled efficiently.

The diameter of the circumscribed circle of the blower fan unit of the present invention is preferably 80mm or less. The shape of the blower fan unit is not necessarily limited to a perfect circle, and therefore, in the case where the blower fan unit is not a perfect circle, the diameter of the circumscribed circle is taken as the size of the blower fan unit. If the diameter of the circumscribed circle of the blower fan unit is 80mm or less, the feeling of incongruity when worn is small, and the design is not impaired, and the outside air can be introduced between the clothing and the body by the blower fan unit, and the clothing is excellent in wearing comfort, and therefore, is preferable. In addition, a sufficient amount of air for introducing the external air into the laundry can be obtained, and noise when the blower fan unit is driven is reduced, which is preferable. The diameter of the circumscribed circle of the blower fan unit is more preferably 70mm or less, still more preferably 60mm or less, and particularly preferably 50mm or less.

The axial thickness of the fan of the blowing fan unit is preferably 3-30 mm. It is preferable that the thickness of the fan in the axial direction is 3mm or more because a sufficient amount of air for introducing the outside air into the clothes can be obtained. The thickness of the fan in the axial direction is more preferably 5mm or more, and still more preferably 7mm or more. On the other hand, if the thickness of the fan in the axial direction is 30mm or less, the feeling of incongruity when worn is small, and the design is not impaired, which is preferable. The thickness of the fan in the axial direction is more preferably 25mm or less, and still more preferably 20mm or less.

In the clothing of the present invention, the number of the blowing fan units is not particularly limited, and the blowing fan units can be mounted to the clothing according to the diameter of the circumscribed circle of the blowing fan units and the thickness of the fan in the axial direction within the range that does not impair the wearing feeling, the design, and the like.

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. In the present invention, the upper garment refers to a garment worn on the upper body, and the lower garment refers to a garment worn on the lower body. Specific examples of the top in the present invention include underwear such as underwear, vest, and camisole, general clothing such as T-shirt, polo shirt, knit T-shirt (Cut and Sew), pajamas, shirt, jacket, and coveralls, and sports clothing such as sports underwear and sports sweater, but are not limited thereto. Specific examples of the underclothes in the present invention include underwear such as underpants, general clothing such as casual pants, shorts, skirts, pyjamas, and coveralls, and sportswear such as sport shorts, but are not limited thereto.

The clothing of the present invention can suppress the stuffiness feeling and the summer heat feeling in the clothing, and keep the internal environment of the clothing comfortable, and is excellent in wearing comfort, and therefore, the clothing of the present invention can be suitably used in various wearing situations requiring comfort, such as high-temperature and/or high-humidity environments, offices, outdoors, and indoors.

Examples

The present invention will be described in more detail below with reference to examples. The characteristic values in the examples were obtained by the following methods.

A. Moisture absorption Rate Difference (. DELTA.MR)

Fibers constituting clothes were used as a sample, hot air-dried at 60 ℃ for 30 minutes at the beginning, and then left to stand in an Espek-made constant temperature and humidity machine LHU-123 humidified to have a humidity of 65% RH at 20 ℃ for 24 hours, and the mass W1(g) of the sample was measured. Then, the mixture was allowed to stand in a constant temperature and humidity apparatus adjusted to a humidity of 90% RH at 30 ℃ for 24 hours, and the mass W2(g) of the sample was measured. Then, the sample was dried with hot air at 105 ℃ for 2 hours, and the mass W3(g) of the sample after absolute drying was measured. The moisture absorption rate MR1 (%) when the sample was left to stand for 24 hours at 20 ℃ and 65% RH from the absolute dry state was calculated by the following formula using the masses W1 and W3 of the sample, the moisture absorption rate MR2 (%) when the sample was left to stand for 24 hours at 30 ℃ and 90% RH from the absolute dry state was calculated by the following formula using the masses W2 and W3 of the sample, and the moisture absorption difference (Δ MR) was calculated by the following formula.

MR1(％)＝{(W1-W3)/W3}×100

MR2(％)＝{(W2-W3)/W3}×100

Difference in moisture absorption rate (. DELTA.MR) (%). MR2-MR1

The moisture absorption difference (Δ MR) was determined as an average value of 5 measurements of 1 sample.

B. Degree of air permeability

The air permeability was measured by taking the fabric obtained in examples and the materials constituting the air inlet and outlet used in examples as samples, and the air permeability was measured in accordance with JIS L1096: 2010 (method for testing woven fabric and knitted fabric) 8.26.1 (method a). The measurement was performed 5 times for each 1 sample, and the average value was defined as the air permeability (cm)³/cm²In s). In addition, in the case where the air inlet and/or the air outlet are provided by cutting out the fabric, since the fabric is not present in this portion, the air permeability is "not suitable".

C. Comfort (smoldering thermal, hot and sweat)

For the evaluation of comfort, 20 subjects were put on the clothes produced in the examples and carried out under 3 conditions of "before air supply", "during air supply" and "after air supply" in a room with an outdoor environment in summer assumed to have a temperature of 30 ℃ and a humidity of 90% RH. The clothes produced in the examples were not provided with a blower fan unit "before blowing" and were evaluated for comfort after 30 minutes of continuous walking. With regard to "blowing", immediately after the evaluation of "before blowing", a blower fan unit was attached to the clothes produced in the examples, and the comfort after the clothes continued to travel for 30 minutes while blowing was evaluated. With respect to "after air blowing", immediately after the evaluation of "during air blowing" was performed, air blowing from the blower fan unit was stopped, and comfort after traveling for 30 minutes was evaluated. Regarding the internal state of the clothes under the conditions of "before air blowing", "during air blowing" and "after air blowing", 5 points were not sensed at all, "4 points were not sensed at all," 3 points were sensed at least for any of stuffiness, sunstroke and sweat coolness, "2 points were sensed at any of stuffiness, sunstroke and sweat coolness," 1 point was sensed at any of stuffiness, sunstroke and sweat coolness, and the average score of the scores evaluated by 20 subjects was calculated and found to be acceptable if the average score was 3.0 points or more.

D. Design property

For design, after the blower fan unit was attached to the clothes produced in the examples, the appearance of the clothes was evaluated by 20 subjects wearing the clothes. "the air inlet, the air outlet, and the blower fan unit are all inconspicuous and can be worn without any problem" is 5 points, "the air inlet, the air outlet, and the blower fan unit are all hardly conspicuous and do not repel wearing" is 4 points, "the air inlet, the air outlet, and the blower fan unit are all noticed but can be worn" is 3 points, "the air inlet, the air outlet, and the blower fan unit are conspicuous and therefore repel wearing" is 2 points, "the air inlet, the air outlet, and the blower fan unit are conspicuous and therefore strongly repel wearing" is 1 point, the average score of the scores respectively evaluated by 20 subjects is calculated, and the average score is 3.0 points or more.

Example 1

Fig. 1 (a) is a schematic explanatory view of a clothes back surface portion showing the position of an inlet in embodiment 1. A plain weave fabric was produced by weaving using nylon fibers (false twisted yarn of 50dtex-98 f) as warp and weft by a usual method, and then sewn to produce a long-sleeved shirt. Next, a circular shape having a diameter of 50mm was cut out at a position of 2 points of the lower back surface as an air inlet for a wearing test. Further, a cylindrical blower fan unit having an outer diameter of 48mm and a fan axial thickness of 5mm was attached to the position of the inlet, and then the blower fan unit was connected to an external power source by a cable, and the flow rate of air from the blower fan unit was set to 2.0m³Permeability test was performed per minute. The evaluation results of the obtained fabrics and clothes are shown in table 1.

The clothes of example 1 were suppressed in stuffiness, sunstroke and sweat-cold feeling in the clothes under any conditions of before, during and after air blowing, and were able to maintain comfortable environment in the clothes with or without air blowing from the blower fan unit, and were excellent in comfort and design.

Examples 2 to 6 and comparative examples 1 and 2

In example 2, the yarn was changed to a false-twisted yarn of "QUUP" (registered trademark) 33dtex-26f manufactured by Toshiy chemical Co., Ltd., nylon fiber as a moisture-absorbing material, in example 3, the sea-island type composite fiber (false-twisted yarn of 66dtex-72 f) described in example 3, International publication No. 2018/012318 as a moisture-absorbing polyester fiber, in example 4, the yarn was changed to a false-twisted yarn of "Lynda" (registered trademark) 84dtex-20f manufactured by Mitsubishi chemical Co., Ltd., acetate fiber, in example 5, the spun yarn of British cotton count 60S (equivalent to 98dtex) was changed to a spun yarn of "Bemberg" (registered trademark) 84dtex-45f manufactured by Asahi chemical Co., Ltd., in example 6, and in comparative example 1, the yarn was changed to a false-twisted yarn of "Pylen" (registered trademark) 56dtex (30 f manufactured by Mitsubishi chemical Co., Ltd., polypropylene fiber, clothes were produced in the same manner as in example 1 except that in comparative example 2, the polyester fiber was changed to a non-hygroscopic false twist yarn of "Tetron" (registered trademark) 84dtex-36f manufactured by Toray corporation, and a wearing test was carried out. The evaluation results of the obtained fabrics and clothes are shown in table 1.

The clothes of examples 2 to 6 were suppressed in stuffiness, sunstroke and sweat-cold feeling in the clothes under any conditions of before, during and after air blowing, and were able to maintain a comfortable environment in the clothes with or without air blowing from the blower fan unit, and were excellent in comfort and design. While the clothes containing cellulose fibers (examples 4 to 6) felt a little cold feeling before and after the air blow, the clothes containing hygroscopic nylon fibers (example 2) and the clothes containing hygroscopic polyester fibers (example 3) felt little cold feeling. The clothes of comparative examples 1 and 2 are comfortable by the air blowing from the blower fan unit during the air blowing, but they are not clothes containing hygroscopic fibers, and therefore feel stuffy and hot before and after the air blowing, and are poor in comfort.

Examples 7 to 9 and comparative example 3

Clothes were produced in the same manner as in example 1, except that the moisture-absorbent polyester fibers used in example 3 and the polyester fibers used in comparative example 2 were each interwoven at a blending ratio shown in table 2 to produce a fabric, and a wearing test was performed. The evaluation results of the obtained fabrics and clothes are shown in table 2.

The clothing of comparative example 3 was comfortable by the air blown from the blower fan unit during the air blowing, but the comfort was poor because the moisture-absorbent polyester fibers were mixed at a low rate, and thus a stuffy feeling and a hot feeling were felt before and after the air blowing.

Examples 10 and 11 and comparative examples 4 and 5

Clothes were produced in the same manner as in example 1 except that the air permeability of the fabric was changed as shown in table 2, and a wearing test was performed. The evaluation results of the obtained fabrics and clothes are shown in table 2.

The clothes of examples 10 and 11 were suppressed in stuffiness, sunstroke and sweat coldness in the clothes under any conditions of before, during and after air blowing, and were able to maintain a comfortable environment in the clothes with or without air blowing from the blower fan unit, and were excellent in comfort and design. The clothes of comparative examples 4 and 5 are excellent in comfort by suppressing the stuffiness feeling, the sunstroke feeling, and the sweat-cooling feeling in the clothes before and after the air blowing, but they are poor in comfort because the air permeability is high, and therefore, the external air introduced into the clothes by the air blowing from the blower fan unit cannot be efficiently circulated in the clothes during the air blowing, and the stuffiness feeling and the sunstroke feeling are not sufficiently suppressed.

Examples 12 to 18 and comparative example 6

Fig. 1 (b) to (i) are schematic explanatory views of the clothes back surface portion showing the positions of the intake port and the exhaust port in examples 12 to 18 and comparative example 6, respectively.
