Description
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, offices, and homes.
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 are one of effective means for reducing the amount of carbon dioxide discharged. However, when the air conditioning temperature is changed, there is a problem that the comfort of the indoor space such as an office and a house is lowered, and particularly, the indoor space feels uncomfortable due to stickiness caused by perspiration in summer. Therefore, there is proposed a clothing for maintaining comfort by feeding outside air into the clothing using a fan.
For example, patent document 1 proposes an air-conditioning suit having a surface material and a lining material, which is provided with a fan for introducing outside air, and which is capable of forcibly generating an air flow in a space between the surface material and the lining material. According to this proposal, the air flow is forcibly generated in the space between the surface material and the lining, whereby the body can be cooled efficiently.

Problems to be solved by the invention
According to the technique disclosed in patent document 1, the air flow is forcibly generated in the space between the surface material and the lining of the air-conditioning suit, and the body can be efficiently cooled. However, this technique is a structure in which air is filled into clothes (between a surface fabric and a lining), and therefore, a fan having a large flow rate of air blowing needs to be mounted, and the clothes are largely swollen, and therefore, the technique is not suitable for wearing in offices, homes, and the like from the viewpoint of design.
Further, according to the technique disclosed in patent document 2, the body can be cooled by introducing air from the outside into the clothes by the blower provided in the tubular ventilation portion communicating with the internal space of the clothes. However, this technique requires the air blower to be attached to the waist using a belt or the like, and is uncomfortable to wear due to the uncomfortable feeling. In this technique, in order to prevent air that has flowed into the clothes from flowing out through the fabric of the clothes main body, a fabric that is not permeable to air, such as a taffeta fabric, is used, and the air flows out only through the cuffs and the neckline. Therefore, the air blower is not suitable for wearing in offices, homes, and the like from the viewpoint of design because the clothes are largely swollen when the air blower is operated.
The present invention has been made to solve the problems of the prior art described above, and an object of the present invention is to provide clothing which can suppress stuffiness and sunstroke in clothing, maintain comfortable environment in clothing, and is excellent in both design and wearing comfort in wearing occasions such as offices and homes.

The present invention will be described in detail below.
For the clothes, the air permeability of the fabric is 50-500 cm3/cm2The/s is important. The air permeability of the fabric in the present invention is a value measured by the method described in examples. By making the air permeability of the fabric be 50cm3/cm2At least s, preferably 70cm3/cm2At least s, more preferably 90cm3/cm2At least s, more preferably 100cm3/cm2At least s, the transpiration property of sweat is excellent, and therefore, the stuffiness feeling during sweating can be suppressed, and the swelling of clothes can be suppressed. In addition, the air permeability of the fabric is 500cm3/cm2Less than s, preferably 450cm3/cm2(ii) less than s, more preferably 400cm3/cm2Is less than s, more preferably 350cm3/cm2The fabric has good mechanical properties, good process passability and good handling properties when producing clothes, and good durability when in use. In addition, the fabric is not too thin, and can be worn without uncomfortable feeling even if the lining is not provided.
The garment of the present invention preferably comprises a fabric at least partially using hygroscopic fibers. By using the hygroscopic fiber in the fabric, the release of moisture to the outside of the garment is promoted, and the moisture in the vicinity of the portion using the hygroscopic fiber is reduced, thereby making it possible to provide the garment with a more suppressed stuffiness. Specific examples of the moisture-absorbing fibers include, but are not limited to, polyester-based moisture-absorbing fibers, polyamide-based fibers, polyacrylic fibers, rayon-based fibers, acetate-based fibers, cotton, hemp, silk, and wool. Among them, polyester-based moisture-absorbing fibers and polyamide-based fibers are preferable because they are excellent in mechanical properties and durability.
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%. 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 external humitures. 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. By setting the Δ MR of the moisture-absorbent fiber to preferably 2.0% or more, more preferably 3.0% or more, and even more preferably 4.0% or more, the stuffy feeling and sticky feeling in the clothing can be reduced, and the clothing can be worn with excellent wearing comfort. Further, by setting the Δ MR of the hygroscopic fiber to preferably 10.0% or less, more preferably 9.0% or less, and even more preferably 8.0% or less, the process passability and the handling property in the production of a fabric or a garment are good, and the garment is excellent in durability in use.
The laundry of the present invention preferably has at least 1 suction port for introducing external air into the laundry. Here, the air inlet does not mean an opening portion such as a collar, sleeves, and bottom of a trouser, which is generally provided in clothes, but is a portion which is separately provided to introduce external air into the clothes and has higher air permeability than a basic portion of the clothes. 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. 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 inlet provided in the garment of the present invention is preferably made of a material having a higher air permeability than the fabric constituting the basic part (garment main body) of the garment. 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. The air permeability of the inlet is not particularly limited, but is preferably 400cm3/cm2More than s.
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 provided in a normal garment, but is a portion which is provided separately corresponding to the air inlet and has a higher air permeability than a basic portion of the garment for discharging air in the garment to the outside of the garment. The provision of such an exhaust port can promote ventilation in the clothing, and therefore, the thermal sensation and stuffiness can be suppressed, and the clothing can be worn with excellent wearing comfort. 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.
The vent provided in the garment of the present invention is preferably made of a material having a higher air permeability than the fabric of the garment.

The single fiber fineness of the fibers used for 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 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. The single fiber fineness is preferably 0.5dtex or more, more preferably 0.6dtex or more, and further preferably 0.8dtex or more, whereby the clothing is reduced in yarn breakage, has good process passability, is reduced in the generation of fluff during use, and has excellent durability. Further, since the single fiber fineness is preferably 4.0dtex or less, more preferably 2.0dtex or less, and further preferably 1.5dtex or less, the clothing does not impair flexibility of the clothing and is excellent in wearing comfort.
The breaking strength of the fiber 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, and is preferably 2.0 to 5.0cN/dtex from the viewpoint of mechanical properties.

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 clothing of the present invention to have a blower fan 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 opening portions such as the collar and the sleeve, and thus the body can be cooled efficiently.
The fan mounted on the blower fan unit provided in the clothing of the present invention is preferably a centrifugal fan or a blower fan that blows air in a direction substantially perpendicular to the axial direction of the fan. By using the centrifugal fan or the blower, the outside air having directivity in a direction substantially parallel to the body can be easily sent out, and the body can be efficiently cooled. Further, by blowing air in a direction substantially parallel to the body, the clothes are less likely to swell than in the case of blowing air in a direction substantially perpendicular to the body, and therefore, the clothes have excellent design properties.
The blower fan unit provided in the clothing of the present invention preferably has a fan with an outer diameter of 10 to 60 mm. By setting the outer diameter of the fan to preferably 10mm or more, more preferably 15mm or more, and further preferably 20mm or more, a sufficient amount of air for sending the outside air into the clothes can be obtained. By setting the outer diameter of the fan to 60mm or less, more preferably 55mm or less, and still more preferably 50mm or less, the noise at the time of driving the fan can be reduced and the size of the blower fan unit main body can be reduced, so that the blower fan unit with less discomfort in wearing can be obtained.
The blower fan unit provided in the clothing of the present invention preferably has a fan axial thickness of 3 to 20 mm. By setting the thickness of the fan in the axial direction to preferably 3mm or more, more preferably 4mm or more, and further preferably 5mm or more, a sufficient air volume for sending the outside air into the clothes can be obtained. Further, since the thickness of the fan in the axial direction is preferably 20mm or less, more preferably 17mm or less, and further preferably 15mm or less, the air blowing unit main body can be made thin, so that the uncomfortable feeling during wearing is reduced, and the clothing is excellent in wearing comfort.
The blower fan unit provided in the clothing of the present invention is preferably housed in a casing having an air inlet and an air outlet in order to prevent the clothing and fingers from being caught in the fan. The contents stored in the case are not particularly limited, and examples thereof include a case in which only the fan and the motor are stored as the contents, and a case in which a battery, a power switch, and the like are stored as the contents in addition to the fan and the motor. When the battery or the power switch is not housed in the casing, the blower fan unit is preferably connected to the casing via a wire such as a power supply line having connection terminals at both ends.
The weight of the blower fan unit provided in the clothing of the present invention is preferably 200g or less. By setting the weight to preferably 200g or less, more preferably 100g or less, and further preferably 50g or less, the feeling of weight is not easily felt when wearing the garment, and the garment is excellent in wearing comfort.
In the clothing of the present invention, it is important to provide a flow path forming portion for providing directivity to the wind in the clothing inside the clothing. The flow path forming portion for providing directivity to the wind in the clothes is a portion for forming a ventilation flow path by normalizing the flow of the wind fed from the blower fan unit into the clothes to a specific direction. As a result of intensive studies on clothes that can suppress stuffiness and swelling in the clothes and can efficiently cool the body, the present inventors have found that clothes including a fabric having a certain air permeability are provided with a blower fan unit, and a flow path forming portion for providing directivity to the wind in the clothes is provided on the inner side of the clothes, and thus the clothes can be suitably used in various wearing situations such as offices and homes. In general, when a blower fan unit is provided to clothes having high air permeability, swelling of the clothes and stuffiness in the clothes can be suppressed, but it is difficult to obtain clothes having excellent wearing comfort because wind escapes to the outside of the clothes before reaching a part of the body to be cooled. In view of the above problem, the present invention has been made to provide a ventilation flow path actively by providing a flow path forming portion for providing directivity to wind in clothes inside the clothes, so that wind can be induced to a portion of a body to be cooled, and design and wearing comfort can be improved significantly.
The flow path forming portion will be described below with reference to fig. 1. Fig. 1 (a) is a front view showing a flow path forming part in clothes according to an embodiment of the present invention, fig. 1 (b) is a side view thereof, and fig. 1 (c) is a cross-sectional view thereof.
In the clothing shown in fig. 1, the convex portion 1 as a flow path forming portion extends in one direction. That is, the convex portions 1a and 1b arranged at intervals of approximately the same width as the blowing opening of the blower fan unit 2 are attached to the clothing fabric 3, and the convex portions 1a and 1b are continuously provided in the substantially blowing direction of the blower fan unit 2. In the present invention, the flow path forming section is not necessarily formed of a convex flow path material as long as it can provide directivity to the wind in the clothes. For example, the flow path forming portion may be formed by sewing a garment material into a bag shape in cross section and filling a filler in the bag shape. The number of the convex portions constituting the flow path forming portion is not particularly limited, and it is preferable to form a plurality of convex portions such as 2 or more depending on the size of the clothes from the viewpoint of forming the ventilation flow path by restricting the wind blown by the blower fan unit.
In the clothing of the present invention, it is important that the length L of the convex portion 1 extending in one direction is 30 to 500 mm. The length L of the convex portion in the present invention is a value measured by the method described in examples. By setting the length L of the convex portion to 30mm or more, preferably 50mm or more, and more preferably 70mm or more, it is possible to efficiently discharge air and moisture in the clothes to the outside of the clothes, and to provide the clothes in which the stuffiness and the summer heat are suppressed. Further, by setting the length L of the convex portion to 500mm or less, preferably 450mm or less, and more preferably 400mm, the clothing is less uncomfortable due to contact between the body and the convex portion and is excellent in wearing comfort.
The convex part 1 formed in the clothing of the invention preferably has a thickness T of 3-20 mm. The thickness T of the convex portion in the present invention is a value measured by the method described in examples. By setting the thickness T of the convex portion to preferably 3mm or more, more preferably 5mm or more, and further preferably 7mm or more, a ventilation flow path can be formed in the clothing, so that air in the clothing can be efficiently replaced, and the clothing is excellent in wearing comfort. Further, by setting the thickness T of the convex portion to preferably 20mm or less, more preferably 17mm or less, and further preferably 15mm or less, the clothing is less uncomfortable due to contact between the body and the convex portion, has excellent wearing comfort, does not cause the convex portion to float in appearance, and has excellent design.
The convex part 1 formed on the clothing of the invention preferably has a width W of 5 to 30 mm. The width W of the convex portion in the present invention is the width of each convex portion, and is a value measured by the method described in examples. By setting the width W of the convex portion to preferably 5mm or more, more preferably 8mm or more, and further preferably 10mm or more, collapse of the convex portion due to the movement of the body can be suppressed, and the shape of the ventilation flow path can be maintained. Further, by setting the width W of the convex portion to be preferably 30mm or less, more preferably 25mm or less, and further preferably 20mm or less, the contact area with the body can be reduced, and the uncomfortable feeling during wearing can be suppressed.
In the case where the convex portions 1 formed in the garment of the present invention are formed of a plurality of convex portions, the interval between adjacent convex portions may be kept constant as shown in fig. 1 or may vary depending on the position. Fig. 3 is a schematic explanatory view showing the installation angle of the plurality of convex portions. When the distance between the adjacent convex portions 1a and 1b is changed depending on the position, as shown in fig. 3, the convex portions are preferably attached so that the distance between the convex portions becomes wider as the convex portions are farther from the air blowing port, and the attachment angle a (the angle formed by the adjacent convex portions) is preferably 20 ° or less. By setting the installation angle of the convex portion to preferably 20 ° or less, more preferably 10 ° or less, and further more preferably 5 ° or less, directivity can be given to the wind inside the clothing, and thus the body can be cooled efficiently. The attachment angle when the adjacent convex portions 1a and 1b are attached in parallel is 0 °, and the attachment angle is negative as the distance from the air outlet becomes larger and the interval between the adjacent convex portions 1a and 1b becomes smaller. Therefore, the lower limit of the installation angle of the convex portion is preferably 0 °.
The flow path forming part provided in the clothing of the present invention preferably includes a fiber structure. By including the fiber structure in the flow path forming section, the feeling of discomfort at the portion in contact with the skin is reduced, and the garment is flexible and can follow the movement of the body, thereby providing a garment having excellent wearing comfort. As the fiber structure, not only a general machine-knitted fabric such as a double-sided Raschel (double Raschel) but also a nonwoven fabric, a knitted fabric, a lace, a rope (rope), and a composite material thereof may be used.
The positions of the blower fan unit and the flow path forming portion provided in the clothing of the present invention may be appropriately selected according to the form of the clothing and the wearing situation, and for example, it is preferable that the air flow fan unit is provided on the back and the underarm portion so that air flows from the lower portion to the upper portion. In the human body, local cooling and ventilation of the back portion where the skin moisture content is large and the operation is not complicated and the underarm portion where the perspiration content is large are effective means for cooling the body efficiently, and are also preferable from the viewpoint of promoting the chimney effect (that is, a phenomenon in which air warmed by the human body moves from the lower portion to the upper portion in the clothes).
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 keep the internal environment of the clothing comfortable because the stuffiness and the summer heat feeling in the clothing are suppressed, and is excellent in wearing comfort and design property, and therefore, can be suitably used in various wearing occasions requiring comfort, such as high-temperature and/or high-humidity environments, offices, and homes.
