Description

[Technical Field]

[0001] The present disclosure relates to a cooling garment, a cooling garment set, and a method for wearing the cooling garment set, which cools the body by evaporating moisture absorbed in a nonwoven fabric. [Background technology]

[0002] As a measure to combat the heat and heatstroke outdoors in summer, cooling clothing is known, which is made by providing a surface of moisture-absorbing material on clothing such as a vest that can be worn by people or animals such as dogs, and absorbs heat through the heat of vaporization caused by the evaporation of the moisture, thereby cooling the body (see Patent Document 1).

[0003] In Patent Document 1, a water inlet is provided at the top of the cooling suit, and a plastic bottle is inserted into the inlet, and water from the plastic bottle is sent through the inlet to a water-absorbing material provided inside the cooling suit. The water absorbs heat by evaporation, cooling the body. Furthermore, in Patent Document 1, a plurality of V-shaped water partitions are distributed on the cooling suit, allowing water to spread over the entire surface of the water-absorbent material. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6008301 Summary of the Invention [Problem to be solved by the invention]

[0005] Generally, the higher the moisture permeability (JIS L 1099:2012 A-1 method) of a cooling suit, the cooler a person feels when wearing it. This is because the amount of vapor evaporating from the cooling suit increases. The ability of a cooling suit to make a person feel cooler is hereafter referred to as cooling performance. On the other hand, the lower the moisture permeability of the cooling suit, the less steam evaporates from the cooling suit, and the longer the time that the cooling suit keeps the person feeling cool. The longer the cooling suit can keep a person cool, the better, and this performance will be hereinafter referred to as durability. The cooling suit in Patent Document 1 does not disclose a method for simultaneously achieving both cooling performance and durability, nor does it disclose the moisture permeation control layer of the present application that limits the amount of vapor released from the intermediate layer. In view of the above problems, the present disclosure provides a cooling suit that simultaneously satisfies cooling performance and durability. The present invention also provides a cooling garment set using the cooling garment and a method for wearing the cooling garment set. [Means for solving the problem]

[0011] Specific embodiments of the present disclosure will be described below. However, more detailed descriptions than necessary may be omitted. For example, detailed descriptions of well-known matters or redundant descriptions of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. Note that the inventors provide the accompanying drawings and the following description to enable those skilled in the art to fully understand the present disclosure, and do not intend for them to limit the subject matter described in the claims. In the following description, identical or similar components are designated by the same reference numerals. (Embodiment 1)

[0012] First, the overall configuration of the cooling suit 1 (also referred to as a water-cooled cooling suit) will be described, and then each component will be described in detail. (Overall cooling suit)

[0013] Hereinafter, an outline of a cooling suit 1 according to one embodiment of the present disclosure will be described with reference to the drawings. Figure 1 is a front perspective view from the right showing the general configuration of the cooling suit 1 in embodiment 1, Figure 2 is a general front view of the cooling suit 1 in embodiment 1, and Figure 3 is a general back view of the cooling suit 1 in embodiment 1. 1 means a perspective view of the front as seen from the right side of the cooling suit 1. This definition is also applied to the following description.

[0014] As shown in FIGS. 1 and 8A, the central axis of the cooling suit 1 (the central axis of the person) when the cooling suit 1 is worn on the person's body is defined as a center line 92. Furthermore, with the cooling suit 1 being worn on a person's body as a reference, the left-hand side of the center line 92 is defined as the left side, and the right-hand side is defined as the right side. Furthermore, when the cooling suit 1 is worn on a person's body, the side closest to the person's body is defined as the inside, and the side farthest from the person's body is defined as the outside. Furthermore, when the cooling suit 1 is worn on a person's body, the head side is defined as the upper side and the foot side as the lower side. Furthermore, the term "human body" includes both naked (skin only) and clothed bodies. Furthermore, the term "water" includes, for example, cold water chilled in a refrigerator, as well as water at room temperature (the temperature of the environment in which people live).

[0015] 2, the cooling suit 1 has an outer fabric 2 placed on the front side of the body, an inner fabric 3 placed on the back side of the body, a left fabric 4 placed on the left side of the body, a right fabric 5 placed on the right side of the body, and a zipper 7 placed in the center of the outer fabric 2. The cooling suit 1 also has reinforcing lines 6 that reinforce the edges.

[0016] An intermediate layer 31 made of nonwoven fabric that absorbs water and vaporizes the absorbed water by body heat is provided inside the front fabric 2 and the back fabric 3. The intermediate layer 31 will be described in detail later.

[0017] The pressure-bonded portion 11 is a portion where the outer layer 30, the moisture permeation control layer 33, and the inner layer 32 are tightly adhered together by pressure bonding, joining, or adhesion (FIG. 5A). The pressure-bonded portion 11 confines the intermediate layer 31 in the front fabric 2 and the back fabric 3, and is a linear portion where the front layer 30 and the inner layer 32 are pressure-bonded together, and is a continuous line drawn in one stroke.

[0018] 1 and 2, the front fabric 2 has a plurality of water retention sections 13 that retain water. Details of the water retention sections 13 will be described later, but the water retention sections 13 have a hole 10 (black circle) that penetrates the front fabric 2 at their center.

[0019] As shown in FIG. 3, like the front fabric 2, the back fabric 3 also has a plurality of water retaining portions 13 that retain water, an intermediate layer 31, and a pressure-bonded portion 11. The intermediate layer 31 is made of a single continuous nonwoven fabric inside the front fabric 2 and the back fabric 3. As described above, the intermediate layer 31 is confined inside the front fabric 2 and the back fabric 3 by the pressure-bonded portions 11. The intermediate layer 31 may be separated and confined inside the front fabric 2 and inside the back fabric 3, or the two separated intermediate layers 31 may be joined together to form a single layer.

[0020] The back fabric 3 is provided with a water inlet 20 at its upper part for supplying water to the intermediate layer 31, and a drain outlet 21 at its lower part for draining water absorbed by the intermediate layer 31. Here, the upper part refers to a position above half of the cooling suit 1, and the lower part refers to a position below half of the cooling suit 1. In the case of Figure 3, the drain outlet 21 is arranged at the left end of the back fabric 3 so that when a person sits on a chair or the like, the body is not pushed by the drain outlet 21. The drain outlet 21 may also be arranged at the right end.

[0021] As shown in Figure 1-3, a left fabric 4 and a right fabric 5 are provided so that the front fabric 2 and the back fabric 3 fit the body when a person wears the cooling suit 1. The left fabric 4 and the right fabric 5 connect the front fabric 2 and the back fabric 3 and are made of a stretchable material such as rubber. The left fabric 4 and the right fabric 5 may have a plurality of holes to improve breathability.

[0022] Next, each component will be described in detail. (Water inlet and outlet) FIG. 4 is a schematic rear view of the cooling suit 1 of the first embodiment, and shows an enlarged view of the water inlet 20 and the drain outlet 21. When the cooling suit 1 is worn, the water inlet 20 has an outer lid 24 positioned far from the body and an inner lid 25 positioned close to the body. The outer lid 24 and the inner lid 25 are in contact with each other in the front-to-back direction, and form a closure 34 together to prevent water in the intermediate layer 31 from leaking out from the inside.

[0023] The outer lid 24 has a protrusion that can be gripped by hand. The outer lid 24 has a protrusion 26 on the inside, and the inner lid 25 has a recess 27 on the outside. By pressing the outer lid 24 against the inner lid 25, the convex portion 26 and the concave portion 27 are engaged, preventing the water in the intermediate layer 31 from leaking out from the inside.

[0024] The water injected from the water inlet 20 is absorbed into the intermediate layer 31 of the back fabric 3 and also spreads and is absorbed into the intermediate layer 31 of the front fabric 2, so that the water spreads over the entire surface of the cooling suit 1.

[0025] The water inlet 20 may be configured with a hook-and-loop fastener such as Magic Tape (registered trademark), a waterproof zipper, or a waterproof fastener that prevents water from leaking out from the inside of the intermediate layer 31. The drain port 21 may have the same structure as the water inlet 20, but may be of a different size. The drain outlet 21 and the water inlet 20 may be provided in the front fabric 2.

[0026] (Outer and inner fabrics) FIG. 5A is a schematic cross-sectional view of the cooling suit 1 of the first embodiment, showing the cross section taken along line AA in FIG. As shown in FIG. 5A, the outer fabric 2 has a waterproof inner layer 32 positioned closest to the body, a breathable outer layer 30 positioned farthest from the body, an intermediate layer 31 positioned above the inner layer 32 and made of a nonwoven fabric that absorbs and stores absorbed water, and a breathability control layer 33 positioned between the intermediate layer 31 and the outer layer 30 and that limits the amount of vapor (moisture) released from the intermediate layer 31.

[0027] The material of the inner layer 32 is preferably a waterproof material such as nylon. The material of the inner layer 32 may be made antistatic by using antistatic yarn such as a hydrophilic polymer.

[0028] The material of the intermediate layer 31 is a nonwoven fabric, and is preferably a material such as polyurethane moisture-wicking polyester fleece, technology interlining polyester fleece, or a direct-spun fiber containing a polymer whose main component is polyacrylic acid sodium salt. The intermediate layer 31 may be made of a polymer absorbent material. The material of the intermediate layer 31 is not particularly limited to the above materials, as long as it is a material that can absorb water and easily evaporate the absorbed water.

[0029] The material of the moisture permeation control layer 33 is preferably a material that has both waterproofness to prevent water from passing through the intermediate layer 31 and moisture permeability to allow vapor (moisture) of the intermediate layer 31 to pass through. As will be described later, if the moisture permeation control layer 33 is made of the same type of material, by increasing the thickness of the moisture permeation control layer 33, the amount of vapor (moisture) from the intermediate layer 31 that passes through the moisture permeation control layer 33 to the outside can be reduced. Thermoplastic polyurethane is preferably used for the moisture permeation control layer 33. There are two types of thermoplastic polyurethane: a non-porous film and a porous film. A non-porous film is a film with few tiny holes (air bubbles). A porous film is a film with many tiny holes (air bubbles). Both non-porous and porous films have tiny holes (cells). The number of holes (cells) per unit area of ​​a porous film is greater than the number of holes (cells) per unit area of ​​a non-porous film. If the thickness of a non-porous film and that of a porous film are the same, the porous film will allow a greater amount of vapor (moisture) from the intermediate layer 31 to pass through the moisture permeation control layer 33 to the outside.

[0030] As shown in FIGS. 5A and 5B, two methods for forming the moisture permeation control layer 33 on the surface of the face layer 30 will be described. The first method is to form the moisture permeation control layer 33 into a thin film, and then to attach the film-like moisture permeation control layer 33 and the front layer 30 by thermocompression bonding or the like. The second method is as follows: (1) A solution for the moisture permeation control layer 33 is poured into the surface layer 30. (2) The poured solution for the moisture permeation control layer 33 is dried. (3) When the drying is completed, the moisture permeation control layer 33 is formed on the surface of the face layer 30 .

[0031] The method of bonding the pressure-bonded portion 11 (three layers: the outer layer 30, the moisture permeation control layer 33, and the inner layer 32) in FIGS. 5A and 5B will be described. As shown in Figures 5A and 5B, when high-frequency welding is performed with the surface layer 30, the moisture permeation control layer 33, and the inner layer 32 stacked together, the moisture permeation control layer 33 rubs against the surface layer 30, and the moisture permeation control layer 33 rubs against the inner layer 32, generating heat, causing the moisture permeation control layer 33 to melt partially or entirely, and bonding the surface layer 30 and the inner layer 32 together. The bonding method of the pressure-bonding portion 11 may be heat welding.

[0032] The material of the outer layer 30 is preferably a material that has moisture permeability and is compatible with the moisture permeation control layer 33, such as a nylon material or a polyester material. The material of the outer layer 30 may be cotton or other materials. The material of the outer layer 30 is preferably a breathable material such as 50% nylon jersey and 50% polyurethane. The material of the front layer 30 may be made antistatic by using antistatic yarn or the like.

[0033] Flame-retardant fibers may be used for the material of the outer layer 30 and / or the material of the inner layer 32. In addition, the material of the outer layer 30 and / or the material of the inner layer 32 may be subjected to a flame-retardant treatment. Examples of flame-retardant fibers and fibers that have been flame-retarded include Vinal (registered trademark), polyetherimide (PEI) fiber, Moeny (registered trademark), Conex (registered trademark), Super Ecstar (registered trademark), Anfla (registered trademark), Heim (registered trademark), Protecta (registered trademark) FR, Honoguard (registered trademark), Brevano (registered trademark), and Nonex (registered trademark).

[0034] 5A, the cooling suit 1 has a pressure-bonded section 11 in which the outer layer 30, the moisture permeation control layer 33, and the inner layer 32 are closely adhered by pressure-bonding, joining, or bonding. A gap 12 is formed between the pressure-bonded section 11 and the intermediate layer 31. In other words, the pressure-bonded section 11 on the outer edge of the cooling suit 1 surrounds the intermediate layer 31 via the gap 12. The pressure-bonded section 11 on the outer edge of the cooling suit 1 does not have an intermediate layer 31. The cooling suit 1 may not have the gap 12, and the intermediate layer 31 may be in contact with the pressure-bonded portion 11 on the outer edge.

[0035] The back fabric 3 has the same structure and material as the front fabric 2.

[0036] (Water holding part) In FIG. 2, when water drips from the shoulders of the cooling suit 1 to the bottom of the cooling suit 1, the water retaining portion 13 retains the water. As shown in Figure 5B, the water retention portion 13 has a hole 10 that penetrates the front fabric 2 and the back fabric 3, a pressure-bonded portion 11 that tightly bonds the front layer 30, the moisture permeation control layer 33, and the inner layer 32 around the hole 10, and a void 12 that is located around the pressure-bonded portion 11 and between the front layer 30 and the inner layer 32. Water is stored in the gap 12 and thereby held in the water holding portion 13 .

[0037] The water holding portion 13 will now be described in detail. The water holding portion 13 temporarily stores water. More specifically, when water is supplied to the intermediate layer 31 from the water inlet 20 , the water is temporarily stored in the voids 12 of the water retaining portion 13 . In this state, when the water held in the intermediate layer 31 adjacent to the void 12 evaporates, the amount of water held in the intermediate layer 31 decreases. Then, due to the capillary phenomenon of the intermediate layer 31, the water stored in the void 12 moves from the void 12 to the intermediate layer 31 and is absorbed. As time passes, all of the water stored in the voids 12 moves to the intermediate layer 31 and the water in the voids 12 disappears.

[0038] (drainage operation) 6A and 6B are schematic operational diagrams showing how water is drained from the intermediate layer 31 of the cooling suit 1 in the first embodiment. As a premise, the intermediate layer 31 of the cooling suit 1 is in a state in which water has already been absorbed. First, as shown in FIG. 6A, the closing portion 34 (FIG. 4) of the water inlet 20 is closed, and the closing portion 34 of the water outlet 21 is opened. Next, when the upper part of the cooling suit 1 begins to be rolled up, the water in the upper part of the middle layer 31 of the outer fabric 2 is squeezed out and moves to the lower part of the middle layer 31. Finally, as shown in FIG. 6B, when the rolling up of the cooling suit 1 is nearing completion and the drainage is almost complete, the blocking portion 34 of the drain port 21 is closed.

[0039] By the above operation, the water in the intermediate layer 31 is drained, and water can be poured in through the water pouring port 20. If water can be repeatedly poured in and drained, water can be supplied to the cooling suit 1 any number of times (for example, four times a day), and the cooling suit 1 can cool the body. Furthermore, when a person is wearing the cooling suit 1, gravity tends to cause water to accumulate under the outer fabric 2 or the inner fabric 3. Excess water accumulated under the outer fabric 2 or the inner fabric 3 can be drained from the drain outlet 21.

[0040] Example 1 [Table 1] Table 1 shows the relationship between the moisture permeability (JIS L 1099:2012 A-1 method) of the front fabric 2 or the back fabric 3, evaluation item 1, evaluation item 2, and the thickness of the moisture permeability control layer 33.

[0041] The horizontal axis of Table 1 represents the moisture permeability of the front fabric 2 or the back fabric 3, which conforms to the JIS L 1099:2012 A-1 method. The moisture permeability represents the amount of water that evaporates from the intermediate layer 31 per hour per square meter of the front fabric 2 or the back fabric 3. The vertical axis of Table 1 represents evaluation item 1, evaluation item 2, and the thickness of the moisture permeation control layer 33.

[0042] Evaluation item 1 represents the cooling performance of the cooling suit 1. Specifically, for evaluation item 1 (cooling performance), an experiment was conducted in the following manner. First, 500 ml of water at 25°C was poured into the cooling suit 1 and allowed to spread throughout the intermediate layer 31. Then, when a person wore the cooling suit 1 in an environment of 25°C and 50% RH, it was examined whether or not they felt a cool sensation in the chest and back for 5 minutes. In Table 1, if a cold sensation was felt for 5 minutes, it is indicated by a circle, and if a cold sensation was not felt before 5 minutes had passed, it is indicated by an X.

[0043] Evaluation item 2 indicates the durability of the cooling suit 1. Specifically, for evaluation item 2 (sustainability), an experiment was conducted using the following method. First, 500 ml of water at 30° C. is poured into the cooling suit 1 and allowed to spread throughout the intermediate layer 31. The weight of the cooling suit 1 at this time is measured (this weight measurement result is defined as weight 1). Next, the cooling suit 1 is left in an environment of 30°C and 50% RH for 72 hours. Next, the cooling suit 1 is left to stand, and then the weight of the cooling suit 1 is measured (the result of the weight measurement is referred to as weight 2). Finally, weight 2 is subtracted from weight 1 to calculate the amount of water remaining in cooling suit 1. In Table 1, if the amount of water remaining in cooling suit 1 is 50 ml or more, it is indicated by a circle, and if the amount of water remaining in cooling suit 1 is less than 50 ml, it is indicated by an X.

[0044] In Table 1, the type and thickness (mm) of the moisture permeation control layer 33 are listed in the row below evaluation item 2.

[0045] Moisture permeability (ml / (m) that meets evaluation item 1 2 ×H)) is 12.5 or more. Moisture permeability (ml / (m) that satisfies evaluation item 2 2 ×H)) is greater than or equal to 0 and less than or equal to 62.5. Therefore, the moisture permeability (ml / (m)) that satisfies both evaluation items 1 and 2 is 2 ×H)) is greater than or equal to 12.5 and less than or equal to 62.5. Therefore, it is preferable that the moisture permeability (JIS L 1099:2012 A-1 method) of the front fabric 2 or the back fabric 3 of the cooling suit 1 be 12.5 or more and 62.5 or less.

[0046] Moisture permeability (ml / (m 2 The moisture permeation control layer 33 that achieved a ×H) of 12.5 was a non-porous film with a thickness of 0.15 mm. Moisture permeability (ml / (m 2 The moisture permeation control layer 33 that achieved a value of 62.5×H) was a porous film with a thickness of 0.10 mm. As shown in Table 1, if the moisture permeability control layer 33 is made of the same type of material, it can be seen that by increasing the thickness of the moisture permeability control layer 33, the amount of vapor (moisture) from the intermediate layer 31 that passes through the moisture permeability control layer 33 to the outside can be reduced (when the moisture permeability in Table 1 is 12.5 and 29.2, and when the moisture permeability is 45.8 and 62.6).

[0047] (Variation 1) FIG. 7 is a rear view showing the general configuration of the cooling suit 100 in the first modification. The cooling suit 1 of the first embodiment (FIG. 3) is provided with one water inlet 20 in the upper part of the back fabric 3 and one water outlet 21 in the lower part of the back fabric 3. On the other hand, in the first modification, as shown in FIG. 7, a single water inlet / outlet port 40 is provided at the lower end of the back fabric 3 for injecting water into the cooling suit 1 and draining water from the cooling suit 1 at the same time. The water inlet / outlet 40 has a normal cap structure, and when the part of the water inlet / outlet 40 indicated by the solid line in FIG. 7 is pinched and pulled, the cap opens and the opening indicated by the broken line becomes visible. According to the above embodiment, water can be poured and drained using one water pouring / draining port 40, so the area of ​​the intermediate layer 31 can be increased, and the amount of water that can be retained can be increased.

[0048] (Variation 2) 8A and 8B are schematic perspective views showing the operation of layering the cooling suit 1 of the present disclosure and the air-conditioning suit 50 (also called the Air-Conditioned Fuujin Suit (registered trademark)) in Modification 2. FIG. FIG. 8A is a diagram showing a case where a person wears the cooling suit 1, and FIG. 8B is a diagram showing a case where an air-conditioning suit 50 is worn over the cooling suit 1. As described in Japanese Utility Model Publication No. 3-32487 and Japanese Patent Publication No. 6536674, air-conditioning clothing 50 is clothing equipped with a fan 51 that blows outside air into the clothing, evaporating sweat from the body and lowering the body temperature. The air-conditioning clothing 50 is also called EF wear or fan-equipped workwear.

[0049] The operation of layering the cooling suit 1 and the air-conditioning suit 50 will now be described. First, as shown in FIG. 8A, the cooling suit 1, which has already been filled with water, is put on the body and the zipper 7 is fastened. Next, as shown in FIG. 8B, the air-conditioning suit 50 is layered over the cooling suit 1, and the air-conditioning suit 50 is fastened with a zipper. Finally, the fan 51 of the air-conditioning clothing 50 is rotated to send outside air into the clothing. The combination of the layered cooling suit 1 and the air-conditioning suit 50 is called a cooling suit set.

[0050] According to the above embodiment, the air-conditioning suit 50 sends outside air to the surface of the cooling suit 1, facilitating the evaporation of water in the cooling suit 1 and enabling the body temperature to be lowered quickly. Although the fan 51 is rotated after putting on the air-conditioning suit 50, the air-conditioning suit 50 with the fan 51 rotating may be worn over the cooling suit 1.

[0051] The cooling suit 1 may be worn inside out (reverse) on the body, and the reversed cooling suit 1 and the air-conditioning suit 50 may be worn over each other. The operation of layering the reversed cooling garment 1 and the air-conditioning garment 50 is the same as that shown in FIG. 8B, and therefore will not be described here.

[0052] According to the above embodiment, the front layer 30 of the front fabric 2 and the front layer 30 of the back fabric 3 of the cooling suit 1 are positioned closest to the body, so that water in the intermediate layer 31 can evaporate through the front layer 30 and lower body temperature without sweating. Furthermore, the air-conditioning suit 50 sends outside air into the cooling suit 1, promoting evaporation of the cooling suit 1 and enabling the body temperature to be lowered quickly.

[0053] The cooling suits 1, 100 may have the water inlet 20 and the drain outlet 21 on the inside thereof, taking into consideration the design of the outside. Specifically, the water inlet 20 may be provided on the upper inside of the right or left side of the front fabric 2 or on the upper inside of the back fabric 3. Furthermore, a drainage port 21 may be provided on the lower inside of the right or left side of the front fabric 2 or on the lower inside of the back fabric 3.

[0054] According to the above aspect, the cooling suit 1 has the same water inlet and outlet functions as the cooling suit 1 of embodiment 1, and has a water inlet 20 and an outlet 21 on the inside of the cooling suit 1, thereby preventing the outer design of the cooling suit 1 from being damaged. Furthermore, since the water inlet 20 and the drain outlet 21 are provided inside the cooling suit 1, the cover of the water inlet 20 or the cover of the drain outlet 21 can be prevented from being caught on something and opening.

[0055] (Embodiment 2) In embodiment 2, an inner layer 32 having moisture permeability and waterproofness is provided closest to the human body, and a moisture permeability control layer 33 (also referred to as a first moisture permeability control layer 33a) is placed on top (outside) of the inner layer 32. 9A is a schematic cross-sectional view of the cooling suit 101 of the second embodiment, corresponding to the cross section AA in FIG. 2, and FIG. 9B is a schematic cross-sectional view of the cooling suit of the second embodiment, corresponding to the cross section BB in FIG. 9A , the front fabric 2 or the back fabric 3 comprises, in order of proximity to the human body, an inner layer 32 that is breathable and waterproof, a moisture permeation control layer 33, an intermediate layer 31, and an outer layer 30 that is not breathable but waterproof. On both sides of the front fabric 2 or the back fabric 3, there are arranged pressure-bonded sections 11 where the inner layer 32, the moisture permeation control layer 33, and the outer layer 30 are bonded. The front fabric 2 or the back fabric 3 has a gap 12 between the pressure-bonded section 11 and the intermediate layer 31.

[0056] Similarly, in Figure 9B, the outer fabric 2 or the inner fabric 3 comprises, in order of proximity to the human body, an inner layer 32 that is breathable and waterproof, a breathability control layer 33, an intermediate layer 31, and an outer layer 30 that is not breathable but waterproof. The front fabric 2 or the back fabric 3 has an inner layer 32, a moisture permeation control layer 33, and holes 10 penetrating the front layer 30. The front fabric 2 or the back fabric 3 has a gap 12 between the pressure-bonded portion 11 and the intermediate layer 31 . The front fabric 2 or the back fabric 3 has a pressure-bonded portion 11 where the inner layer 32, the moisture permeation control layer 33, and the front layer 30 are bonded together so as to surround the hole 10. The hole 10, the pressure-bonded portion 11, and the gap 12 form a water holding portion 13.

[0057] According to the above embodiment, the breathable and waterproof inner layer 32 is disposed closest to the body in the front fabric 2 and / or the back fabric 3 of the cooling suit 101, so that when water in the intermediate layer 31 evaporates, the evaporated water passes through the inner layer 32 and comes into contact with the human body. As a result, the water that comes into contact with the human body evaporates, allowing the human body temperature to be reduced without sweating.

[0058] 10A and 10B are alternative embodiments to FIGS. 9A and 9B, respectively. 10A is another schematic cross-sectional view of the cooling suit 102 in embodiment 2, corresponding to the AA cross section in FIG. 2, and FIG. 10B is another schematic cross-sectional view of the cooling suit 102 in embodiment 2, corresponding to the BB cross section in FIG. 2. 10A, the front fabric 2 or the back fabric 3 includes, in order of proximity to the human body, a breathable and waterproof inner layer 32, a first breathable control layer 33a, an intermediate layer 31, a second breathable control layer 33b, and a breathable and waterproof front layer 30. On both sides of the front fabric 2 or the back fabric 3, there are arranged pressure-bonded portions 11 where the inner layer 32, the first breathable control layer 33a, the second breathable control layer 33b, and the front layer 30 are bonded. The first moisture permeation control layer 33a and the second moisture permeation control layer 33b can be made of the same material as the moisture permeation control layer 33 described in the first embodiment. The front fabric 2 or the back fabric 3 has a gap 12 between the pressure-bonded portion 11 and the intermediate layer 31 .

[0059] Similarly, in Figure 10B, the outer fabric 2 or the inner fabric 3 comprises, in order of proximity to the human body, an inner layer 32 having breathability and waterproofness, a first breathability control layer 33a, an intermediate layer 31, a second breathability control layer 33b, and an outer layer 30 having breathability and waterproofness (both sides in Figure 10B). The front fabric 2 or the back fabric 3 has holes 10 penetrating through the inner layer 32 , the first moisture permeation control layer 33 a , the second moisture permeation control layer 33 b , and the front layer 30 . The front fabric 2 or the back fabric 3 has a gap 12 between the pressure-bonded portion 11 and the intermediate layer 31 . The front fabric 2 or the back fabric 3 has a pressure-bonded portion 11 arranged around the hole 10 to bond the inner layer 32, the first moisture permeation control layer 33a, the second moisture permeation control layer 33b, and the front layer 30. The hole 10, the pressure-bonded portion 11, and the gap 12 form a water holding portion 13.

[0060] According to the above embodiment, the breathable and waterproof inner layer 32 is disposed closest to the body in the front fabric 2 and / or the back fabric 3 of the cooling suit 102, so that when water in the intermediate layer 31 evaporates, the evaporated water passes through the inner layer 32 and comes into contact with the human body. As a result, the water that comes into contact with the human body evaporates, allowing the human body temperature to be reduced without sweating. Furthermore, when water in the intermediate layer 31 evaporates, the evaporated water passes through the moisture-permeable and waterproof outer layer 30 and is expelled to the outside, thereby further lowering body temperature.

[0061] (Embodiment 3) In the third embodiment, the drain outlet 21 (in which the outer lid 24 is pressed against the inner lid 25) in FIG. 4 is replaced with a screw-type chap type. 4, for example, when a person wearing the cooling suit 1 sits in a chair with a backrest, such as a car chair, the outer lid 24 comes into contact with the backrest. If the person's posture changes and the outer lid 24 opens for some reason, there is a risk that water in the intermediate layer 31 will leak out of the drain outlet 21. The third embodiment is an embodiment that improves this problem.

[0062] FIG. 11 is a schematic diagram of the drain port 22 in the third embodiment and an enlarged schematic diagram of the drain port 22. As shown in FIG. As shown in FIG. 11, the drain outlet 22 has a structure similar to that of a PET bottle (registered trademark), and includes a cap nut 41, a cap bolt 42, and a connecting member 43. The connecting member 43 connects the cap nut 41 and the cap bolt 42 to prevent the cap nut 41 from being lost. The end of the connecting member 43 on the cap nut 41 side and the cap nut 41 are connected so that the cap nut 41 can rotate relative to the end of the connecting member 43.

[0063] When the cap nut 41 and the cap bolt 42 are brought into contact with each other and the cap nut 41 is rotated, for example, clockwise, the cap nut 41 is screwed onto the cap bolt 42. Then, the cap nut 41 and the cap bolt 42 are firmly fixed together.

[0064] According to the above embodiment, even if a person wearing cooling suit 103 sits in a chair with a backrest, such as a car chair, cap nuts 41 and cap bolts 42 are firmly fixed, so water in intermediate layer 31 can be prevented from leaking out of drain hole 22.

[0065] The drain hole 22 may be formed of a waterproof fastener that prevents water from leaking out from the inside of the intermediate layer 31.

[0066] (Embodiment 4) In the fourth embodiment, the structure of the cooling suits 1, 100-103 is used in a hat. 12A is a schematic perspective view of the hat 60 in the fourth embodiment, FIG. 12B is a schematic perspective view of the hat 60 in the fourth embodiment in an upside-down state, and FIG. 13 is a schematic plan view of the hat 60 in the fourth embodiment.

[0067] As shown in FIGS. 12A, 12B, and 13, the hat 60 mainly comprises a crown 61, a brim 62, and a length adjustment member 66. The hat 60 further has a water inlet 63 located at the top of the hat 60 (here, the apex of the hat 60), a drain outlet 64 located at the bottom of the hat 60, an intermediate layer 31, a water retention portion 65, and a crimped portion 68. The mid layer 31 is disposed over the entire interior surface of the crown 61 . The crimping portion 68 is disposed at the bottom of the cap 60 so as to surround the periphery of the cap 60 . The structure of the crown 61 of the hat 60 is the same as that of the outer fabric 2 or the inner fabric 3 of the cooling suits 1, 100-103 of the above-described embodiments 1-3.

[0068] The basic mechanism of the hat 60 will now be described. First, water is poured into the crown 61 from the water inlet 63 located at the top of the hat 60 . The poured water is then absorbed by the intermediate layer 31 and spreads across the intermediate layer 31 at the bottom of the hat 60 . Next, when a person puts on the hat 60 filled with water, the water in the middle layer 31 evaporates due to the heat of the head and / or the heat of the hat 60 heated by sunlight. The heat of evaporation cools the head. Finally, when water needs to be drained from the hat 60, a person rolls up the hat 60, and the water in the middle layer 31 is drained to the outside of the hat 60 through the drain hole 64 located at the bottom of the hat 60.

[0069] According to the above embodiment, water can be easily poured into the hat 60 through the water inlet 63 located at the top of the hat 60. Furthermore, when it is desired to drain water from the hat 60, a person can roll up the hat 60, and the water in the middle layer 31 can be easily drained to the outside of the hat 60 through the drain outlet 64 located at the bottom of the hat 60.

[0070] In order to perform both the water filling operation and the water draining operation, the cap 60 only needs to be provided with either the water filling port 63 or the water draining port 64.

[0071] (Embodiment 5) The fifth embodiment is a hat 70 different from the fourth embodiment. FIG. 14 is a schematic plan view of another hat 70 according to the fifth embodiment. As shown in Fig. 14, the crown 61 is divided into sections by a plurality of crimped portions 68. In Fig. 14, four crimped portions 68 divide the crown 61 into four sections. A water inlet 63 similar to the water inlet 63 of the fourth embodiment is provided at the top (vertex) of the crown 61.

[0072] According to the above embodiment, a person pours water into the inside of the hat 70 (crown 61) from the single water inlet 63 provided at the apex of the hat 70, so that the water spreads evenly in all compartments. As a result, the water spreads over the entire surface of the crown 61. (Embodiment 6) The sixth embodiment is a hat 80 that is different from the fifth embodiment. FIG. 15 is a schematic plan view of another hat 80 according to the sixth embodiment. As shown in Fig. 15, the crown 61 is divided into sections by the crimped portions 68. In Fig. 15, the crown 61 is divided into four sections by the four crimped portions 68. At least one water inlet 63 is provided for each compartment at the top of the hat 70 .

[0073] According to the above embodiment, the crown 61 of the hat 80 is divided into sections by the crimped portion 68, and at least one water pouring spout 63 is provided at the top of the hat 70 for each section. A person pours water into the inside of the hat 80 (crown 61) from the plurality of water inlets 63, so that the water is distributed evenly in all the compartments. As a result, the water is distributed over the entire surface of the crown 61.

[0074] (Embodiment 7) In the seventh embodiment, a slide mechanism is employed for the water pouring port 63 described above. FIG. 16 is a schematic plan view of the water inlet 71 in the seventh embodiment. As shown in FIG. 16, the water inlet 71 has a slide body 75 , a slide lid 72 , a slide groove 73 , and a water inlet opening 74 .

[0075] The water inlet opening 74 supplies water to the mid layer 31 inside the crown 61 . The slide body 75 is a substantially rectangular parallelepiped, and has the slide lid 72 inside. The slide cover 72 can be moved left and right on the paper surface by a person's finger. The left side of FIG. 16 shows the slide cover 72 positioned on the left side of the slide body 75. In this case, the water inlet opening 74 is closed by the slide lid 72, and the water in the intermediate layer 31 inside the crown 61 does not leak out to the outside of the crown 61.

[0076] The right side of FIG. 16 shows the slide cover 72 positioned on the right side of the slide body 75. In this case, the slide lid 72 opens the water inlet opening 74, allowing the water in the intermediate layer 31 inside the crown 61 to be discharged to the outside of the crown 61.

[0077] (Embodiment 8) The eighth embodiment is an aspect of a hat cover 120 using a radiative cooling material 85 (hereinafter simply referred to as hat cover 120). FIG. 17 is a schematic perspective view showing the state before the hat cover 120 in the eighth embodiment is put on the hat 60 in the fourth embodiment. FIG. 18 is a schematic perspective view of the eighth embodiment after the hat cover 120 is placed on the hat 60 of the fourth embodiment.

[0078] The hat cover 120 is placed over the hat 60, and is made of a radiation cooling material 85, which will be described later. The hat 60 may be the above-mentioned hats 70 and 80.

[0079] As shown in FIG. 17, the hat cover 120 has one hat cover opening 121 at the top (vertex) of the hat cover 120 and a plurality of hat cover holes 122 at the bottom of the hat cover 120.

[0080] The hat 60 has a plurality of hat cover fixing members 123 at the bottom of the hat 60 of the fourth embodiment. The hat cover fixing member 123 is passed through the hat cover hole 122 of the hat cover 120 to fix the hat cover 120 to the hat 60, and is preferably made of rubber or resin. The hat cover fixing member 123 has an upper fixing member 124, a middle fixing member 125, and a lower fixing member 126. The hat cover fixing member 123 is preferably cylindrical, but is not limited to a cylindrical shape as long as it can fix the hat cover hole 122. The diameter (perimeter) of the intermediate fixing member 125 is smaller than the diameter (perimeter) of the upper fixing member 124 and the diameter (perimeter) of the lower fixing member 126 (see the enlarged view of FIG. 17). Furthermore, the diameter (circumferential length) of the hat cover hole 122 is smaller than the diameter (circumferential length) of the upper fixing member 124 and the diameter (circumferential length) of the lower fixing member 126, and is larger than or equal to the diameter (circumferential length) of the intermediate fixing member 125.

[0081] A method for attaching the hat cover 120 to the hat 60 will now be described. First, as shown in FIG. 17, the hat cover opening 121 of the hat cover 120 is inserted into the water inlet 63 of the hat 60. Next, any one of the upper fixing members 124 is inserted into the corresponding hat cover hole 122, and the hat cover hole 122 is inserted up to the intermediate fixing member 125. Then, the hat cover hole 122 is sandwiched between the upper fixing member 124 and the lower fixing member 125, and the hat cover hole 122 is fixed to the hat 60. Finally, similarly, all the upper fixing members 124 are inserted into the corresponding hat cover holes 122 , and all the hat cover holes 122 are inserted up to the intermediate fixing members 125 . In this manner, the hat cover 120 can be attached to the hat 60 as shown in FIG.

[0082] Since the hat cover hole 122 is located above the lower fixing member 126, a space is formed between the hat cover 120 and the hat 60 at the position of the hat cover hole 122. Therefore, the hat 60 and the radiative cooling material 85 are in partial contact with each other, and there is a partial space between the hat cover 120 and the hat 60.

[0083] The water vapor generated by evaporation from the intermediate layer 31 of the hat 60 is released to the outside of the radiative cooling material 85 through the space in which the hat 60 is partially disposed.

[0084] The radiative cooling material 85 will now be described. The radiative cooling material 85 utilizes the principle of "radiative cooling" to lower the temperature of the radiative cooling material 85 and the environmental temperature in the shade (hereinafter referred to as the shadow temperature) on the opposite side from direct sunlight without using energy by releasing heat into space, even under direct sunlight. As the radiative cooling material 85, for example, the radiative cooling material "SPACECOOL (registered trademark)" from SPACECOOL Co., Ltd. can be used. Depending on the sunlight conditions, the shadow temperature of fabric made of the radiative cooling material "SPACECOOL (registered trademark)" is about 10 degrees Celsius or more lower than the shadow temperature of ordinary fabrics.

[0085] According to the above embodiment, by covering the hat 60 with the hat cover 120 using the radiative cooling material 85, it is possible to cool the person's head more effectively than if the hat 60 were used alone. Furthermore, by providing a partial space between the hat cover 120 and the hat 60, water vapor evaporated from the intermediate layer 31 of the hat 60 is released to the outside of the radiative cooling material 85 through the partially provided space, thereby allowing the person's head to be cooled efficiently.

[0086] The hat cover opening 121 and the water inlet 63 may be structured similarly to the hat cover hole 122 and the hat cover fixing member 123 (with the exception that the center is a hole through which water is supplied to the intermediate layer 31), and the hat cover opening 121 may be fixed to the water inlet 63. In this case, a space is created between the hat cover opening 121 and the hat 60, which is preferable. The cap cover fixing member 123 is not limited as long as it can fix the cap cover 120 to the cap 60 . The upper fixing member 124 may be a lid that can be removed from the intermediate fixing member 125, a pin such as a thumbtack, or a screw-type cap.

[0087] (Embodiment 9) The ninth embodiment is a hooded hat 90. FIG. 19 is a schematic side view of a hooded hat 90 according to the ninth embodiment. As shown in FIG. 19, the hooded hat 90 has a hood 81 below the crown 61. The mid layer 31 is disposed over the entire surface or a portion of the crown 61 and the hood 81 . The crimping portion 68 is located along the lower front portion of the crown 61 and the edge of the hood 81 and is continuous. The drain port 64 is located at the bottom of the hood 81.

[0088] According to the above embodiment, the hood 81 having the intermediate layer 31 can be used to cool the neck and / or shoulders of a person.

[0089] It is preferable that all or part of the front fabric 2 and back fabric 3 of the cooling suits 1, 100-103 of the first to third embodiments are subjected to antibacterial and deodorizing treatment.

[0090] It is preferable that all or part of the hats 60, 70, 80, and 90 of the fourth to ninth embodiments are subjected to antibacterial and deodorizing treatment.

[0091] In embodiment 1, the front fabric 2 and the back fabric 3 have four layers: a front layer 30, a moisture permeability control layer 33, an intermediate layer 31, and an inner layer 32; however, only one of the front fabric 2 or the back fabric 3 may have these four layers. For example, when the back fabric 3 has the four layers, the back fabric 3 has a pressure-bonded portion 11 around its periphery, the pressure-bonded portion 11 surrounds the middle layer 31, and the pressure-bonded portion 11 has the four layers inside. Furthermore, almost all of the front fabric 2 is made up of mesh, and the front fabric 2 does not have these four layers.

[0092] The mesh size of the front fabric 2 is equal to the mesh size of the left fabric 4 or the mesh size of the right fabric 5. The mesh size of the front fabric 2 may be either coarser or finer than the mesh size of the left fabric 4 or the mesh size of the right fabric 5.

[0093] According to the above embodiment, since the front fabric 2 or the back fabric 3 is made of mesh, sweat that evaporates from the body can be expelled through the mesh, reducing stuffiness caused by sweat. In addition, since sweat is less likely to remain on the mesh, the mesh is less likely to absorb sweat odors. Furthermore, since water is supplied to the intermediate layer 31 of only one of the front fabric 2 or the back fabric 3, the amount of water to be injected can be reduced, and the weight of the cooling suit 1, 100 can be reduced. The above effect is particularly effective during hot seasons such as summer. Alternatively, the front fabric 2 may have the four layers, and the back fabric 3 may be made up almost entirely of mesh.

[0094] In the first embodiment, the left fabric 4 and the right fabric 5 are made of a stretchable material, but the stretchable material may be provided with an adjuster that allows for length adjustment. Alternatively, the left fabric 4 and the right fabric 5 may be made of a non-stretchable material and provided with an adjuster.

[0095] The water inlet 20 or the drain outlet 21 in FIG. 3 may be configured with the cap in FIG. 7 may be configured with the water inlet 20 or the water outlet 21 of FIG.

[0096] In the first embodiment, the material of the inner layer 32 and / or the material of the outer layer 30 is / are provided with antistatic properties by using antistatic yarn or the like. However, the present disclosure may also include the following embodiment in which the material of the inner layer 32 and / or the material of the face layer 30 does not use antistatic yarn or the like. This embodiment uses a spin tape that has an anti-static (anti-static) effect. The spin tape has a conductive material kneaded into the fibers of the conductive thread. The spin tape is used by being sewn onto the front and / or back surface of the garment. The spin tape may also be adhered to the front and / or back surface of the garment by bonding, joining, welding, or the like. For example, "STA-GUARD SPIN TAPE" manufactured by Tokai Thermo Co., Ltd. can be used as the spin tape. For the spin tape, for example, "STC60" manufactured by SHINDO Co., Ltd. can be used.

[0097] The spin tape is provided at any position on the cooling suit, such as the shoulders, sides, or sides of the cooling suit.

[0098] In the second modification (FIGS. 8A and 8B), the cooling suit 1 and the air-conditioning suit 50 are layered on top of each other, but the cooling suit 1 may also be layered on top of the following clothing. In this case, the clothing is layered on the outside of the cooling suit 1. Such clothing includes blousons, jackets, work clothes, suits, polo shirts, dress shirts, overalls, white coats (doctor's coats), chef coats, kimonos, firefighter uniforms, and mascot costumes. In addition, as another form of layering, the clothing may be placed inside the cooling suit 1, 100.

[0099] The above-mentioned inventions of the present application can be replaced or combined as long as no contradiction occurs.

[0107] [Item 7] A cooling suit having an outer fabric disposed on the front side of a body and an inner fabric disposed on the back side of the body, The front fabric or the back fabric is a breathable and waterproof inner layer positioned proximate to the body; a waterproof outer layer positioned furthest from the body; an intermediate layer made of a nonwoven fabric disposed below the surface layer and configured to absorb and store the absorbed water; a first moisture permeation control layer disposed between the intermediate layer and the inner layer, the first moisture permeation control layer limiting the amount of vapor emitted from the intermediate layer. According to the above aspect, the moisture-permeable and waterproof inner layer is positioned closest to the body in the outer and / or inner fabrics of the cooling suit, so that when water in the middle layer evaporates, the evaporated water passes through the inner layer and comes into contact with the body. As a result, the water that comes into contact with the body evaporates, allowing the person to lower their body temperature without sweating.

[0108] [Item 8] the outer layer is moisture permeable and waterproof; disposed between the intermediate layer and the outer layer, 8. The cooling garment according to item 7, further comprising a second moisture permeation control layer that limits the amount of vapor released from the intermediate layer. According to the above aspect, when water in the intermediate layer evaporates, the evaporated water passes through the moisture-permeable and waterproof outer layer and is expelled to the outside, thereby further lowering body temperature.
