Description

Cooling clothing and cooling clothing sets

[0001] The present disclosure relates to a cooling garment and a cooling garment set that cools the body by evaporating moisture absorbed in a nonwoven fabric.

[0002] As a measure against 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 vaporizes and absorbs heat, cooling the body. In addition, Patent Document 1 also disperses multiple V-shaped water partitions in the cooling suit, allowing water to spread over the entire surface of the water-absorbing material.

[0004] Patent No. 6008301

[0005] Generally, the higher the moisture permeability (JIS L 1099:2012 A-1 method) of a cooling suit, the cooler the 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 cool a person is hereinafter referred to as "cooling performance." On the other hand, the lower the moisture permeability of a cooling suit, the less vapor evaporates from the cooling suit, and the longer the time the cooling suit keeps the person cool. The longer the cooling suit keeps the person cool, the better, and this performance is hereinafter referred to as "sustaining performance." The cooling suit in Patent Document 1 does not disclose a method for simultaneously achieving both cooling performance and sustaining performance. It also does not disclose the moisture permeability control layer of the present application, which limits the amount of vapor released from the intermediate layer. In consideration of the above-mentioned problems, the present disclosure provides a cooling suit that simultaneously achieves both cooling performance and sustaining performance. It also provides a cooling suit set using the cooling suit and a method for wearing the cooling suit set.

[0006] A cooling suit according to one aspect of the present disclosure is a cooling suit having an outer fabric that is placed on the front side of the body and an inner fabric that is placed on the back side of the body, wherein the outer fabric or the inner fabric has: a waterproof inner layer that is placed close to the body; a middle layer that is placed outside the inner layer and is made of a nonwoven fabric that absorbs water and stores the absorbed water; a breathable outer layer that is placed outside the middle layer; and a breathability control layer that is placed between the middle layer and the outer layer, is formed on the surface of the outer layer, and limits the amount of vapor released from the middle layer.

[0007] Another aspect of the present disclosure provides a cooling garment having an outer fabric placed on the front side of the body and an inner fabric placed on the back side of the body, wherein the outer fabric or the inner fabric has: a breathable outer layer placed away from the body; an intermediate layer placed inside the outer layer and made of nonwoven fabric that absorbs water and stores the absorbed water; a breathable and waterproof inner layer placed inside the intermediate layer; and a first breathability control layer placed between the intermediate layer and the inner layer, formed outside the inner layer, and that limits the amount of vapor released from the intermediate layer.

[0008] The cooling suit according to one aspect of the present disclosure can simultaneously achieve both cooling performance and durability. The cooling suit can also uniformly cool the entire body. The present disclosure also provides a cooling suit set using the cooling suit.

[0010] Specific embodiments of the present disclosure will be described below. However, more detailed descriptions than necessary may be omitted. For example, detailed descriptions of already 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)

[0011] 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)

[0012] An outline of a cooling suit 1 according to one aspect of the present disclosure will now be described with reference to the drawings. Fig. 1 is a front perspective view seen from the right showing the general configuration of the cooling suit 1 according to a first embodiment, Fig. 2 is a schematic front view of the cooling suit 1 according to the first embodiment, and Fig. 3 is a schematic back view of the cooling suit 1 according to the first embodiment. The right-side front perspective view in Fig. 1 refers to a perspective view of the cooling suit 1 as seen by an observer from the right side. This definition will also be applied to the following description.

[0013] As shown in Figures 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, based on the state when the cooling suit 1 is worn on the person's body, 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. Based on the state when the cooling suit 1 is worn on the person's body, the side closer to the person's body is defined as the inside, and the side farther from the person's body is defined as the outside. Based on the state when the cooling suit 1 is worn on the person's body, the head side is defined as the upper side, and the foot side is defined as the lower side. The term "human body" includes both a naked state (skin only) and a state when the person is wearing clothes. The term "water" includes, for example, cold water chilled in a refrigerator and water at room temperature (the temperature of the environment in which the person is present).

[0014] 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.

[0015] 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.

[0016] The pressure-bonded portion 11 is a portion where the front layer 30, the moisture permeation control layer 33, and the inner layer 32 are tightly adhered by pressure bonding, joining, or bonding ( 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.

[0017] 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.

[0018] 3, like the front fabric 2, the back fabric 3 also has a water retention section 13 that retains a plurality of pieces of water, an intermediate layer 31, and a pressure-bonded section 11. Inside the front fabric 2 and the back fabric 3, the intermediate layer 31 is made of a single continuous piece of nonwoven fabric. As described above, the intermediate layer 31 is confined inside the front fabric 2 and the back fabric 3 by the pressure-bonded section 11. The intermediate layer 31 may be confined separately inside the front fabric 2 and the back fabric 3, or the two separate intermediate layers 31 may be joined together to form a single layer.

[0019] The lining 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, "upper" refers to a position above halfway of the cooling suit 1, and "lower" refers to a position below halfway of the cooling suit 1. In the case of Figure 3, the drain outlet 21 is located at the left end of the lining fabric 3 so that the drain outlet 21 does not push against the body when a person sits on a chair or the like. The drain outlet 21 may also be located at the right end.

[0020] 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.

[0021] Next, each component will be described in detail. (Water Inlet and Drain Outlet) Figure 4 is a schematic rear view of the cooling suit 1 of embodiment 1, and Fig. 4 shows enlarged views of the water inlet 20 and drain outlet 21. When the cooling suit 1 is worn as a reference, the water inlet 20 has an outer lid 24 located far from the body and an inner lid 25 located 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 together they form a closure 34 to prevent water from leaking out of the intermediate layer 31.

[0022] The outer lid 24 has a protrusion that can be gripped by hand. The outer lid 24 has a convex portion 26 on the inside, and the inner lid 25 has a concave portion 27 on the outside. When the outer lid 24 is pressed against the inner lid 25, the convex portion 26 and the concave portion 27 engage with each other, preventing water from leaking out of the intermediate layer 31.

[0023] 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.

[0024] The water inlet 20 may be configured with a hook-and-loop fastener such as Velcro (registered trademark), a waterproof zipper, or a waterproof fastener that prevents water from leaking out of the middle layer 31 from the inside. The drain outlet 21 may have the same structure as the water inlet 20 but may be a different size. The drain outlet 21 and the water inlet 20 may be provided in the front fabric 2.

[0025] (Front Fabric and Back Fabric) 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.

[0026] 5A , the outer fabric 2 comprises a waterproof inner layer 32 positioned close to the body, an intermediate layer 31 positioned outside the inner layer 32 and made of a nonwoven fabric that absorbs and stores absorbed water, a breathable outer layer 30 positioned outside the intermediate layer 31, and a moisture transmission control layer 33 positioned between the intermediate layer 31 and the outer layer 30, formed on the surface of the outer layer 30, and restricting the amount of vapor (moisture) released from the intermediate layer 31. The outer fabric 2 may further comprise a fabric such as a mesh fabric on the inner side of the inner layer 32, or a fabric such as a mesh fabric on the outer side of the outer layer 32.

[0027] The following configuration may also be used: 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 made of nonwoven fabric positioned above the inner layer 32 and absorbing and retaining water, and a breathability control layer 33 positioned between the intermediate layer 31 and the outer layer 30 and limiting the amount of vapor (moisture) released from the intermediate layer 31.

[0028] 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.

[0029] The material of the intermediate layer 31 is a nonwoven fabric, and is preferably a material such as polyurethane moisture-wicking polyester fleece, technology-based polyester fleece, or a direct-spun fiber containing a polymer whose main component is polyacrylic acid sodium salt. The material of the intermediate layer 31 may also be a polymer absorbent. The material of the intermediate layer 31 is not limited to the above materials, as long as it is a material that easily absorbs and evaporates the absorbed water.

[0030] The material of the moisture permeation control layer 33 is preferably a material that is both waterproof, preventing water from passing through the intermediate layer 31, and breathable, allowing vapor (moisture) from the intermediate layer 31 to pass through. As described below, if the moisture permeation control layer 33 is made of the same material, increasing the thickness of the moisture permeation control layer 33 can reduce the amount of vapor (moisture) from the intermediate layer 31 that passes through the moisture permeation control layer 33 to the outside. The moisture permeation control layer 33 is preferably made of, for example, thermoplastic polyurethane. There are two types of thermoplastic polyurethane: non-porous film and porous film. Non-porous film is a film with few microscopic holes (air bubbles). Porous film is a film with many microscopic holes (air bubbles). Non-porous film and porous film have microscopic holes (air bubbles). The number of holes (air bubbles) per unit area of ​​a porous film is greater than the number of holes (air bubbles) 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.

[0031] As shown in Figures 5A and 5B, two methods for forming the moisture permeation control layer 33 on the surface of the front layer 30 will be described. In the first method, the moisture permeation control layer 33 is made into a thin film, and the film-like moisture permeation control layer 33 and the front layer 30 are bonded together by thermocompression or the like. In the second method, the following method is performed: (1) A solution for the moisture permeation control layer 33 is poured into the front layer 30. (2) The poured solution for the moisture permeation control layer 33 is dried. (3) Once drying is complete, the moisture permeation control layer 33 is formed on the surface of the front layer 30.

[0032] 5A and 5B, a bonding method for the pressure-bonded portion 11 (three layers: the surface layer 30, the moisture permeation control layer 33, and the inner layer 32) will be described. When high-frequency welding is performed with the surface layer 30, the moisture permeation control layer 33, and the inner layer 32 superimposed as shown in Figures 5A and 5B, 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, and the moisture permeation control layer 33 melts partially or entirely, thereby bonding the surface layer 30 and the inner layer 32 together. Note that the bonding method for the pressure-bonded portion 11 may also be heat welding.

[0033] The material of the front layer 30 is preferably a breathable material that is compatible with the breathability control layer 33, such as nylon or polyester. Alternatively, the material of the front layer 30 may be cotton or other materials. The material of the front 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.

[0034] Flame-retardant fibers may be used for the material of the outer layer 30 and / or the material of the inner layer 32. Furthermore, the material of the outer layer 30 and / or the material of the inner layer 32 may be flame-retardant treated. Examples of flame-retardant fibers and flame-retardant treated fibers that can be used include Bynal (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).

[0035] 5A , the cooling suit 1 has a pressure-bonded portion 11 in which the outer layer 30, the moisture permeability 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 portion 11 and the intermediate layer 31. In other words, the pressure-bonded portion 11 on the outer edge of the cooling suit 1 surrounds the intermediate layer 31 via the gap 12. The pressure-bonded portion 11 on the outer edge of the cooling suit 1 does not have the intermediate layer 31. Note that 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.

[0036] The back fabric 3 has the same structure and material as the front fabric 2.

[0037] 2, when water drips from the shoulders of the cooling suit 1 to the bottom of the cooling suit 1, the water retention section 13 retains the water. As shown in Fig. 5B, the water retention section 13 has a hole 10 penetrating the front fabric 2 and the back fabric 3, a pressure-bonded section 11 around the hole 10 that tightly bonds the front layer 30, the moisture permeation control layer 33, and the inner layer 32, and a void 12 located around the pressure-bonded section 11 and between the front layer 30 and the inner layer 32. Water is retained in the void 12 and thereby retained in the water retention section 13.

[0038] The water retention section 13 will be described in detail. The water retention section 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 retention section 13. In this state, when the water held in the intermediate layer 31 adjacent to the voids 12 evaporates, the amount of water held in the intermediate layer 31 decreases. Then, due to capillary action in the intermediate layer 31, the water stored in the voids 12 moves from the voids 12 to the intermediate layer 31 and is absorbed. After a further period of time, all of the water stored in the voids 12 moves to the intermediate layer 31, and the water in the voids 12 disappears.

[0039] (Drainage Operation) Figures 6A and 6B are schematic diagrams illustrating the operation of draining water from the intermediate layer 31 of the cooling suit 1 in embodiment 1. As a premise, the intermediate layer 31 of the cooling suit 1 has already absorbed water. First, as shown in Figure 6A, the closure portion 34 (Figure 4) of the water inlet 20 is closed, and the closure portion 34 of the drainage port 21 is opened. Next, as the upper part of the cooling suit 1 begins to be rolled up, water is squeezed out from the upper part of the intermediate layer 31 of the outer fabric 2, and the water moves to the lower part of the intermediate layer 31. Finally, as shown in Figure 6B, as the rolling of the cooling suit 1 nears completion and drainage is almost complete, the closure portion 34 of the drainage port 21 is closed.

[0040] The above operation drains water from the intermediate layer 31, allowing water to be poured in through the water inlet 20. If water can be poured in and out repeatedly, water can be supplied to the cooling suit 1 any number of times (for example, four times a day), allowing the cooling suit 1 to cool the body. Furthermore, when a person is wearing the cooling suit 1, gravity tends to cause water to accumulate beneath the outer fabric 2 or the inner fabric 3. Excess water that accumulates beneath the outer fabric 2 or the inner fabric 3 can be drained through the drain outlet 21.

[0041] Example 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 and evaluation item 1, evaluation item 2, and the thickness of the moisture permeability control layer 33.

[0042] 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 (ml) 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 permeability control layer 33.

[0043] Evaluation item 1 represents the cooling performance of the cooling suit 1. Specifically, an experiment for evaluation item 1 (cooling performance) 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 cool in the chest and back for five minutes. In Table 1, cases where a cool sensation was felt for five minutes are indicated by a circle, and cases where a cool sensation was not felt before the five minutes had elapsed are indicated by an X.

[0044] Evaluation item 2 represents the durability of the cooling suit 1. Specifically, an experiment for evaluation item 2 (durability) was conducted using the following method. First, 500 ml of water at 30°C was 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 was measured (this weight measurement result was designated as weight 1). Next, the cooling suit 1 was left for 72 hours in an environment of 30°C and 50% RH. Next, after leaving the cooling suit 1, the weight of the cooling suit 1 was measured (this weight measurement result was designated as weight 2). Finally, weight 2 was subtracted from weight 1 to calculate the amount of water remaining in the cooling suit 1. In Table 1, a case where the amount of water remaining in the cooling suit 1 was 50 ml or more was designated as ◯, and a case where the amount of water remaining in the cooling suit 1 was less than 50 ml was designated as ×.

[0045] In Table 1, the type and thickness (mm) of the moisture permeation control layer 33 are listed in the row below evaluation item 2.

[0046] Moisture permeability (ml / (m) that satisfies evaluation item 1 ２ The moisture permeability (ml / (m × H)) that satisfies evaluation item 2 is 12.5 or more. ２ × H)) is 0 or more and 62.5 or less. Therefore, the moisture permeability (ml / (m ２ Therefore, the cooling suit 1 preferably has a moisture permeability (JIS L 1099:2012 A-1 method) of the front fabric 2 or the back fabric 3 of 12.5 or more and 62.5 or less.

[0047] Moisture permeability (ml / (m) ２ The moisture permeation control layer 33 realizing a moisture permeability (ml / (m × H)) of 12.5 was a non-porous film having a thickness of 0.15 mm.２ The moisture permeation control layer 33 that achieved a moisture permeability of 62.5 was a porous film with a thickness of 0.10 mm. As shown in Table 1, if the moisture permeation control layer 33 is made of the same type of material, it is clear that 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 (when the moisture permeabilities in Table 1 are 12.5 and 29.2, and when the moisture permeabilities are 45.8 and 62.6).

[0048] (Variation 1) Fig. 7 is a rear view showing the schematic configuration of a cooling suit 100 in Variation 1. The cooling suit 1 of Embodiment 1 (Fig. 3) is provided with one water inlet 20 at the top of the lining fabric 3 and one drain outlet 21 at the bottom of the lining fabric 3. On the other hand, Variation 1 is provided with one water inlet / outlet 40 at the end of the bottom of the lining fabric 3, as shown in Fig. 7, which allows water to be poured into the cooling suit 1 and drained from it simultaneously. The water inlet / outlet 40 has a normal cap structure; by pinching and pulling the solid-line portion of the water inlet / outlet 40 in Fig. 7, the cap opens, revealing the dashed-line opening. According to the above embodiment, water can be poured and drained using a single water inlet / outlet 40, thereby increasing the area of ​​the intermediate layer 31 and increasing the water retention capacity.

[0049] (Variation 2) Figures 8A and 8B are schematic perspective views illustrating the act of layering the cooling suit 1 of the present disclosure and air-conditioning suit 50 (also referred to as "Air Conditioning Fuujin Suit (registered trademark)") in Variation 2. Figure 8A illustrates the cooling suit 1 being worn by a person, and Figure 8B illustrates the cooling suit 1 being layered on top of the air-conditioning suit 50. As described in Japanese Utility Model Publication No. Hei 3-32487 and Japanese Patent Publication No. 6536674, air-conditioning suit 50 is equipped with a fan 51 that blows outside air into the suit, evaporating sweat from the body and lowering body temperature. Air-conditioning suit 50 is also referred to as EF wear or fan-equipped workwear.

[0050] The operation of layering the cooling suit 1 and the air-conditioning suit 50 will now be described. First, as shown in Figure 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 Figure 8B, the air-conditioning suit 50 is layered over the cooling suit 1 and the zipper of the air-conditioning suit 50 is fastened. Finally, the fan 51 of the air-conditioning suit 50 is rotated to send outside air into the suit. The combination of the layered cooling suit 1 and the air-conditioning suit 50 is called a cooling suit set.

[0051] According to the above-described embodiment, the air-conditioning suit 50 sends outside air to the surface of the cooling suit 1, accelerating the evaporation of water in the cooling suit 1 and quickly lowering the body temperature. Although the fan 51 is rotated after the air-conditioning suit 50 is put on, the air-conditioning suit 50 with the fan 51 rotating may be worn over the cooling suit 1.

[0052] The cooling suit 1 may be turned inside out (reversed) and worn on the body, and the reversed cooling suit 1 may be layered over the air-conditioning suit 50. The operation of layering the reversed cooling suit 1 over the air-conditioning suit 50 is the same as in Fig. 8B, and therefore will not be described here.

[0053] According to the above-described embodiment, the outer layer 30 of the outer fabric 2 and the outer layer 30 of the inner 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 outer layer 30 and lower body temperature without sweating. Furthermore, the air-conditioning suit 50 sends outside air into the cooling suit 1, accelerating evaporation of the cooling suit 1 and enabling the body temperature to be lowered quickly.

[0054] Note that, taking into consideration the exterior design, the cooling suits 1, 100 may have the water inlet 20 and drain outlet 21 on the inside of the cooling suits 1, 100. 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. The drain outlet 21 may also 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.

[0055] 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 the water inlet 20 and outlet 21 are provided on the inside of the cooling suit 1, which prevents damage to the exterior design of the cooling suit 1. Furthermore, the water inlet 20 and outlet 21 are provided on the inside of the cooling suit 1, which prevents the lid of the water inlet 20 or the lid of the drain outlet 21 from getting caught on something and opening.

[0056] (Embodiment 2) In Embodiment 2, an inner layer 32 having moisture permeability and waterproof properties is provided in a position close to the human body, and a moisture permeability control layer 33 (also referred to as a first moisture permeability control layer 33a) is disposed on (outside of) the inner layer 32. Fig. 9A is a schematic cross-sectional view of a cooling suit 101 in Embodiment 2 corresponding to the A-A cross section in Fig. 2, and Fig. 9B is a schematic cross-sectional view of the cooling suit in Embodiment 2 corresponding to the B-B cross section in Fig. 2.

[0057] 9A , the front fabric 2 or the back fabric 3 is positioned away from the body and includes a breathable front layer 30, an intermediate layer 31 made of a nonwoven fabric that is positioned inside the front layer 30 and absorbs and stores absorbed water, a breathable and waterproof inner layer 32 positioned inside the intermediate layer 31, and a first breathability control layer 33a positioned between the intermediate layer 31 and the inner layer 32 and formed on the outer side of the inner layer 32 to limit the amount of vapor released from the intermediate layer 31. The method for forming the first breathability control layer 33a on the inner layer 32 is the same as the method described in the first embodiment. The front fabric 2 may further include a mesh fabric or other fabric on the inner side of the inner layer 32, or a mesh fabric or other fabric on the outer side of the outer layer 32.

[0058] The front fabric 2 or the back fabric 3 comprises, in order of proximity to the human body, an inner layer 32 having breathability and waterproofness, a breathability control layer 33, an intermediate layer 31, and an outer layer 30 having no breathability but waterproofness. On both sides of the front fabric 2 or the back fabric 3, pressure-bonded portions 11 are arranged where the inner layer 32, the breathability 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 portion 11 and the intermediate layer 31. The inner layer 32 may be arranged closest to the body, and the outer layer 30 may be arranged farthest from the body.

[0059] 9B , 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 moisture permeability control layer 33, an intermediate layer 31, and a breathable but waterproof outer layer 30. The front fabric 2 or the back fabric 3 has the inner layer 32, the moisture permeability control layer 33, and a hole 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 surrounding the hole 10, where the inner layer 32, the moisture permeability control layer 33, and the outer layer 30 are bonded. The hole 10, the pressure-bonded portion 11, and the gap 12 form a water retention portion 13.

[0060] According to the above aspect, 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.

[0061] 10A and 10B are views different from those of FIGS. 9A and 9B, respectively. Fig. 10A is another schematic cross-sectional view of the cooling suit 102 in embodiment 2, corresponding to the cross section A-A in Fig. 2, and Fig. 10B is another schematic cross-sectional view of the cooling suit 102 in embodiment 2, corresponding to the cross section B-B in Fig. 2.

[0062] 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 breathability control layer 33a, an intermediate layer 31, a second breathability 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 at which the inner layer 32, the first breathability control layer 33a, the second breathability control layer 33b, and the front layer 30 are bonded.

[0063] In other words, the outer fabric 2 or the inner fabric 3 has a breathable outer layer 30 positioned away from the body, an intermediate layer 31 positioned inside the outer layer 30 and made of nonwoven fabric that absorbs and stores the absorbed water, an inner layer 32 positioned inside the intermediate layer 31 that is breathable and waterproof, and a first breathability control layer 33a positioned between the intermediate layer 31 and the inner layer 32, formed on the outside of the inner layer 32, and that limits the amount of vapor released from the intermediate layer 31.

[0064] 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 embodiment 1. The method for forming the first moisture permeation control layer 33a on the inner layer 32 and the method for forming the second moisture permeation control layer 33b on the outer layer 30 are the same as those described in embodiment 1. The outer fabric 2 may further include a mesh fabric or other fabric on the inner side of the inner layer 32, or a mesh fabric or other fabric on the outer side of the outer layer 32. The outer fabric 2 or the inner fabric 3 has a gap 12 between the pressure-bonded portion 11 and the intermediate layer 31. The inner layer 32 may be positioned closest to the body, and the outer layer 30 may be positioned farthest from the body.

[0065] 10B , 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 breathability control layer 33a, an intermediate layer 31, a second breathability control layer 33b, and a breathable and waterproof outer layer 30 (both sides of FIG. 10B ). The front fabric 2 or the back fabric 3 has a hole 10 penetrating the inner layer 32, the first breathability control layer 33a, the second breathability control layer 33b, and the outer 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 first breathability control layer 33a, the second breathability control layer 33b, and the outer layer 30 are bonded, arranged around the hole 10. The hole 10 , the pressure-bonded portion 11 and the gap 12 form a water holding portion 13 .

[0066] According to the above-described embodiment, the breathable and waterproof inner layer 32 is positioned closest to the body in the outer fabric 2 and / or inner fabric 3 of the cooling suit 102. Therefore, 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 body temperature to be lowered without the person sweating. Furthermore, when water in the intermediate layer 31 evaporates, the evaporated water passes through the breathable and waterproof outer layer 30 and is discharged to the outside. As a result, the body temperature can be further lowered.

[0067] (Embodiment 3) In Embodiment 3, the drain outlet 21 in Fig. 4 (the system in which the outer lid 24 is pressed against the inner lid 25) is replaced with a screw-type chap system. In the case of the drain outlet 21 in Fig. 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 from the intermediate layer 31 will leak out of the drain outlet 21. Embodiment 3 is an aspect that improves this problem.

[0068] Figure 11 is a schematic diagram of the drain outlet 22 in embodiment 3 and a schematic enlarged view of the drain outlet 22. As shown in Figure 11, the drain outlet 22 has a structure similar to that of a PET bottle (registered trademark) cap, 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.

[0069] 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.

[0070] According to the above aspect, even if a person wearing the cooling suit 103 sits in a chair with a backrest, such as a car chair, the cap nuts 41 and the cap bolts 42 are firmly fixed, so that water in the intermediate layer 31 can be prevented from leaking out of the drain hole 22.

[0071] The drain hole 22 may be formed of a waterproof fastener that prevents water from leaking out of the middle layer 31 from the inside.

[0072] (Embodiment 4) In embodiment 4, the structure of the cooling suits 1, 100-103 is used in a hat. Fig. 12A is a schematic perspective view of hat 60 in embodiment 4, Fig. 12B is a schematic perspective view of hat 60 in embodiment 4 in an upside-down state, and Fig. 13 is a schematic plan view of hat 60 in embodiment 4.

[0073] 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 comprises a water inlet 63 located at the top of the hat 60 (here, the apex of the hat 60), a drain port 64 located at the bottom of the hat 60, an intermediate layer 31, a water retention portion 65, and a pressure-bonding portion 68. The intermediate layer 31 is disposed over the entire interior of the crown 61. The pressure-bonding portion 68 is disposed at the bottom of the hat 60 so as to surround the periphery of the hat 60. The structure of the crown 61 of the hat 60 is the same as the structure of the outer fabric 2 or the inner fabric 3 of the cooling suits 1, 100-103 of the above-described embodiments 1-3.

[0074] The basic mechanism of the hat 60 will now be described. First, water is poured into the crown 61 through the water inlet 63 located at the top of the hat 60. Next, the poured water is absorbed by the midlayer 31 and spreads throughout the midlayer 31 at the bottom of the hat 60. Next, when a person puts the hat 60 with water poured into it on their head, the water in the midlayer 31 evaporates due to the heat of the head and / or the heat of the hat 60 warmed by sunlight. The heat of evaporation cools the head. Finally, to drain the water from the hat 60, the person rolls up the hat 60, and the water in the midlayer 31 is drained to the outside of the hat 60 through the drain outlet 64 located at the bottom of the hat 60.

[0075] According to the above-described 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 intermediate 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.

[0076] 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 .

[0077] (Embodiment 5) Embodiment 5 is a hat 70 different from embodiment 4. Fig. 14 is a schematic plan view of another hat 70 in embodiment 5. As shown in Fig. 14, the crown 61 is divided into sections by a plurality of crimped portions 68. In Fig. 14, the crown 61 is divided into four sections by four crimped portions 68. A water inlet 63 similar to the water inlet 63 in embodiment 4 is provided at the top (vertex) of the crown 61.

[0078] 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.

[0079] (Embodiment 6) Embodiment 6 is a form of a hat 80 different from Embodiment 5. Fig. 15 is a schematic plan view of another hat 80 in Embodiment 6. 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 section at the top of the hat 70.

[0080] According to the above-described embodiment, the crown 61 of the hat 80 is divided into compartments by the crimped portions 68, and at least one water inlet 63 is provided for each compartment at the top of the hat 80. A person pours water into the interior of the hat 80 (crown 61) through the multiple water inlets 63, so that the water is distributed evenly throughout all compartments. As a result, the water is distributed over the entire surface of the crown 61.

[0081] (Embodiment 7) Embodiment 7 is an embodiment in which a slide mechanism is employed in the above-described water inlet 63. Fig. 16 is a schematic plan view of a water inlet 71 in embodiment 7. As shown in Fig. 16, water inlet 71 has a slide body 75, a slide lid 72, a slide groove 73, and a water inlet opening 74.

[0082] The water inlet opening 74 supplies water to the intermediate layer 31 inside the crown 61. The sliding body 75 is a substantially rectangular parallelepiped and has a sliding lid 72 inside. The sliding lid 72 can be moved left and right on the page with a user's finger. The left side of Figure 16 shows the sliding lid 72 positioned on the left side of the sliding body 75. In this case, the sliding lid 72 closes the water inlet opening 74, and water in the intermediate layer 31 inside the crown 61 does not leak out of the crown 61.

[0083] 16 shows a state in which the slide cover 72 is positioned on the right side of the slide body 75. In this case, the slide cover 72 opens the water inlet opening 74, allowing water in the intermediate layer 31 inside the crown 61 to be discharged to the outside of the crown 61.

[0084] (Embodiment 8) Embodiment 8 is a hat cover 120 (hereinafter simply referred to as hat cover 120) using a radiative cooling material 85. Fig. 17 is a schematic perspective view showing the state before the hat cover 120 in embodiment 8 is placed on the hat 60 of embodiment 4. Fig. 18 is a schematic perspective view of the state after the hat cover 120 in embodiment 8 is placed on the hat 60 of embodiment 4.

[0085] The hat cover 120 is placed on the hat 60, and is made of a radiation cooling material 85 described later. The hat 60 may be the hats 70 and 80 described above.

[0086] 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.

[0087] 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 members 123 are passed through the hat cover holes 122 of the hat cover 120 to fix the hat cover 120 to the hat 60, and are preferably made of rubber or resin. The hat cover fixing members 123 have an upper fixing member 124, an intermediate fixing member 125, and a lower fixing member 126. The hat cover fixing members 123 are preferably cylindrical, but are not limited to a cylindrical shape as long as they can fix the hat cover holes 122. The diameter (circumferential length) of the intermediate fixing member 125 is smaller than the diameter (circumferential length) of the upper fixing member 124 and the diameter (circumferential length) of the lower fixing member 126 (see the enlarged view in 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.

[0088] The method of 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 fastening members 124 is inserted into the corresponding hat cover hole 122, and the hat cover hole 122 is inserted up to the intermediate fastening member 125. Then, the hat cover hole 122 is sandwiched between the upper fastening member 124 and the lower fastening member 126, and the hat cover hole 122 is fixed to the hat 60. Finally, in the same manner, all of the upper fastening members 124 are inserted into the corresponding hat cover holes 122, and all of the hat cover holes 122 are inserted up to the intermediate fastening members 125. In this manner, the hat cover 120 can be attached to the hat 60, as shown in FIG. 18 .

[0089] 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.

[0090] 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 partially arranged space.

[0091] 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 on the opposite side of direct sunlight (hereinafter referred to as the shadow temperature) 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 Corporation can be used. Depending on the sunlight conditions, the shadow temperature of fabric made of the radiative cooling material "SPACECOOL (registered trademark)" is approximately 10 degrees Celsius or more lower than the shadow temperature of ordinary fabrics.

[0092] According to the above aspect, 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 by cooling the person's head with the hat 60 alone. Furthermore, by providing a partial space between the hat cover 120 and the hat 60, water vapor vaporized 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. As a result, it is possible to cool the person's head efficiently.

[0093] The hat cover opening 121 and the water inlet 63 may have the same structure as the hat cover hole 122 and the hat cover fixing member 123 (but with a hole in the center to supply water 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 hat cover fixing member 123 is not limited as long as it can fix the hat cover 120 to the hat 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 thumb tack, or a screw-type cap.

[0094] (Embodiment 9) Embodiment 9 is a hooded hat 90. Fig. 19 is a schematic side view of the hooded hat 90 in embodiment 9. As shown in Fig. 19, the hooded hat 90 has a hood 81 below the crown 61. The intermediate layer 31 is disposed over the entire surface or part of the crown 61 and the hood 81. The pressure-bonding portion 68 is disposed along the lower front portion of the crown 61 and the edge of the hood 81, and is continuous. The drain hole 64 is disposed below the hood 81.

[0095] According to the above aspect, the hood 81 having the intermediate layer 31 can be used to cool the neck and / or shoulders of a person.

[0096] (Embodiment 10) Embodiment 10 is a method for manufacturing a cooling garment 1 in which, as shown in Figure 2, the intermediate layer 31 of the front fabric 2 covers the abdomen and thorax, which are the upper body on the front side, and the intermediate layer 31 of the back fabric 3 covers the waist and back on the back side of the body, as shown in Figure 3. Figure 20 is a diagram schematically showing a method for manufacturing the pressure-bonded portion 11 of the front fabric 2 in Figure 2. The upper diagram of Figure 20 is a schematic front view of the front fabric 2, and the lower diagram of Figure 20 is a diagram schematically showing a method for manufacturing the pressure-bonded portion 11 of the front fabric 2 in the CC cross section of Figure 20. Figure 21 is a diagram schematically showing a method for manufacturing the pressure-bonded portion 11 of the back fabric 3 in Figure 3. The upper diagram of Figure 21 is a schematic front view of the back fabric 3, and the lower diagram of Figure 21 is a diagram schematically showing a method for manufacturing the pressure-bonded portion 11 of the back fabric 3 in the D-D cross section of Figure 21. FIG. 22 is a diagram schematically illustrating a method for manufacturing the joining portion of the front fabric 2.

[0097] The manufacturing method of the cooling suit 1 of the tenth embodiment is performed by the following steps (1) to (3): Step (1): Cutting out the front fabric 2 and the back fabric 3 Step (2): First crimping step of the crimped portion 11 of the front fabric 2 and second crimping step of the crimped portion 11 of the back fabric 3 Step (3): Joining the shoulder portion of the front fabric 2 and the shoulder portion of the back fabric 3 Details of steps (1) to (3) will be described below.

[0098] (1) Cutting-out process of the front fabric 2 and the back fabric 3 The front fabric 2 and the back fabric 3 have, from bottom to top, an inner layer 32, an intermediate layer 31, a moisture permeation control layer 33, and a front layer 30 (see FIGS. 20 and 21). The front fabric 2 and the back fabric 3 come in a variety of sizes, from small to large.

[0099] Fig. 23 is a diagram schematically illustrating a method for manufacturing the front fabric 2 and the back fabric 3. As shown in STEP 1 of Fig. 23, the inner layer 32, the intermediate layer 31, the moisture permeation control layer 33, and the front layer 30 of the front fabric 2 and the back fabric 3 are each produced by cutting out from a roll of fabric.

[0100] Specifically, as shown in STEP 2 of Figure 23, the substrates 220 of the inner layer 32, the intermediate layer 31, the moisture permeation control layer 33, and the surface layer 30 are cut out from each of the rolls of the inner layer 32, the intermediate layer 31, the moisture permeation control layer 33, and the surface layer 30.

[0101] (2) First crimping step of the crimped portion 11 of the front fabric 2 and the second crimping step of the crimped portion 11 of the back fabric 3 The first crimping step will be described. As shown in Fig. 20 , the crimped portion 11 is arranged at the outer edge of the front fabric 2. Also, as shown in Fig. 20 , a conductive first mold 201 is arranged above the front fabric 2, and a conductive second mold 202 is arranged below the front fabric 2. A high-frequency generator 210 is arranged between the first mold 201 and the second mold 202, and the high-frequency generator 210 is electrically connected to the first mold 201, and the high-frequency generator 210 is electrically connected to the second mold 202.

[0102] The first mold 201 has a first mold base 201a and a first mold protrusion 201b. The first mold base 201a is a plate-shaped substrate. The first mold protrusion 201b is a protrusion that protrudes from the first mold base 201a in correspondence with the pressure-bonded portion 11 of the outer fabric 2. The second mold 202 has a second mold base 202a and a second mold protrusion 202b. The second mold base 202a is a plate-shaped substrate. The second mold protrusion 202b is a protrusion that protrudes from the second mold base 202a in correspondence with the pressure-bonded portion 11 of the outer fabric 2.

[0103] First, as shown in STEP 3 of Figure 23 , the cut-out substrates 220 of the inner layer 32, intermediate layer 31, moisture permeation control layer 33, and outer layer 30 are laminated in this order on the second mold 202. Next, the area corresponding to the pressure-bonding portion 11 is sandwiched between the first mold convex portion 201b and the second mold convex portion 202b. Next, with the area corresponding to the pressure-bonding portion 11 sandwiched, high-frequency power is supplied to the first mold 201 and the second mold 202 by the high-frequency generator 210. When the high-frequency power is supplied to the first mold 201 and the second mold 202, the high-frequency power is transmitted to the first mold convex portion 202a and the second mold convex portion 202b. Next, the high-frequency power from the first mold base convex portion 201b and the second mold convex portion 202b heats the moisture permeation control layer 33 inside the outer fabric 2, melting the moisture permeation control layer 33. Note that the high-frequency power from the first mold base convex portion 201b and the second mold convex portion 202b may melt a portion of the outer layer 30 and a portion of the inner layer 32. Next, the high-frequency power from the high-frequency generator 210 is stopped, and the first mold 201 is moved upward and / or the second mold 202 is moved downward. The outer fabric 2 is then pulled out from between the first mold 201 and the second mold 202. Finally, the heated moisture permeation control layer 33, a portion of the outer layer 30, and / or a portion of the inner layer 32 are allowed to cool naturally, thereby bonding the outer layer 30, the moisture permeation control layer 33, and the inner layer 32 together. The bonded portions of the outer layer 30, the moisture permeation control layer 33, and the inner layer 32 form the press-bonded portions 11 at the outer edge of the outer fabric 2. The press-bonded portions 11 of the water retention portion 13 are also produced in a similar manner. As described above, the pressed portion 11 on the outer edge of the front fabric 2 and the pressed portion 11 of the water retaining portion 13 are produced in one operation using one set of molds, the first mold 201 and the second mold 202.

[0104] 21 , in the second pressing step, the pressed portions 11 on the outer edge of the backside fabric 3 and the pressed portions 11 of the water retaining portion 13 are also produced in one operation using one set of molds, a third mold 203 and a fourth mold 204. The second pressing step is basically the same as the first pressing step, so a description of the second pressing step will be omitted.

[0105] (3) Joining the Shoulder Portion of the Outer Fabric 2 to the Shoulder Portion of the Inner Fabric 3 The joining process of the shoulder portion of the outer fabric 2 to the shoulder portion of the inner fabric 3 will be described. FIG. 22 is a schematic diagram showing the joining process of the shoulder portion of the outer fabric 2 to the shoulder portion of the inner fabric 3. In FIG. 22, the shoulder portion of the outer fabric 2 is in contact with the shoulder portion of the inner fabric 3. The shoulder portion of the outer fabric 2 includes an outer layer 30a, a moisture permeation control layer 33a, an intermediate layer 31a, and an inner layer 32a. In the outer fabric 2, the position P of the end of the inner layer 32a is shifted to the right on the paper from the position R of the end of the outer layer 30a, the position R of the end of the moisture permeation control layer 33a, and the position Q of the end of the intermediate layer 31a. The shoulder portion of the inner fabric 3 includes an outer layer 30b, a moisture permeation control layer 33b, an intermediate layer 31b, and an inner layer 32b. In the back fabric 3, the position P of the end of the inner layer 32b is shifted to the right on the paper from the position R of the end of the front layer 30b of the back fabric 3, the position R of the end of the moisture permeation control layer 33b, and the position Q of the end of the intermediate layer 31b.

[0106] An adhesive first tape 211 is attached to the upper sides of the front layers 30a and 30b so as to cover the contact areas between the front layers 30a and 30b of the front fabric 2. In addition, an adhesive first tape 211 is attached to the lower sides of the moisture permeation control layers 33a and 33b so as to cover the contact areas between the moisture permeation control layer 33a of the front fabric 2 and the moisture permeation control layer 33b of the back fabric 3.

[0107] A second adhesive tape 212 is attached to the upper and lower sides of the inner layer 32a and the inner layer 32b of the front fabric 2 so as to cover the contact points between the inner layer 32a and the inner layer 32b of the back fabric 3.

[0108] The fifth mold 215 is disposed above the front fabric 2 and the back fabric 3. The fifth mold 215 has a fifth mold base 215a, a fifth mold first convex portion 215b1, and a fifth mold second convex portion 215b2. The fifth mold base 215a is a plate-shaped substrate, and the fifth mold first convex portion 215b1 and the fifth mold second convex portion 215b2 are convex portions protruding from the fifth mold base 215a.

[0109] The sixth mold 216 is disposed below the front fabric 2 and the back fabric 3. The sixth mold 216 has a sixth mold base 216a, a sixth mold first convex portion 216b1, and a sixth mold second convex portion 216b2. The sixth mold base 216a is a plate-shaped substrate, and the sixth mold first convex portion 216b1 and the sixth mold second convex portion 216b2 are convex portions protruding from the sixth mold base 216a.

[0110] A high-frequency generator 210 (not shown) is arranged between the fifth mold 215 and the sixth mold 216, and the high-frequency generator 210 is electrically connected to the fifth mold 215, and the high-frequency generator 210 is electrically connected to the sixth mold 216.

[0111] The joining process is basically the same as the first and second pressure-bonding processes. Differences between the joining process and the first and second pressure-bonding processes are described below. First, the two first tapes 211 are sandwiched between the fifth mold first convex portion 215b1 and the sixth mold first convex portion 216b1. The two second tapes 212 are sandwiched between the fifth mold second convex portion 215b2 and the sixth mold second convex portion 216b2. Finally, the high-frequency generator 210 supplies high-frequency power to the fifth mold 215 and the sixth mold 216 to melt the first tape 211 and the second tape 212. Melting the first tape 211 and the second tape 212 joins the shoulder portion of the front fabric 2 and the shoulder portion of the back fabric 3.

[0112] The shoulder joining process is performed in one step using a set of dies, namely, a fifth die 215 and a sixth die 216 .

[0113] This embodiment prevents water from leaking from the intermediate layer 31 to the outside of the outer fabric 2 and / or the inner fabric 3 from the joint between the shoulders of the outer fabric 2 and the inner fabric 3. As shown in FIG. 22 , the first tape 211 and the second tape 212 are offset from each other so that they do not overlap, ensuring reliable high-frequency welding. The first tape 211 may be located either above the outer layer 30 or below the moisture permeation control layer 33. The second tape 212 may be located either above the inner layer 32 or below the inner layer 32. In particular, when the cooling garment 1 is worn on the body, the upper side of the outer layer 30 is pulled at the shoulders, making it easy to avoid contact with the outer layer 30. Therefore, it is effective to provide the first tape 211 on the upper side of the outer layer 30. Similarly, the second tape 212 is advantageously disposed on top of the inner layer 32 .

[0114] (Embodiment 11) In the cooling suit 1 of embodiment 10, there are cases where an object such as a shoulder bag or an iron pipe repeatedly comes into contact with the joint portion of the shoulder of the cooling suit 1. In such cases, there is room for improvement in that the object rubs against the joint portion, causing the joint portion to peel off and water from the intermediate layer 31 to leak from the joint portion. Therefore, embodiment 11 aims to improve the cooling suit 1 of embodiment 10.

[0115] Fig. 24A is a schematic front view of the cooling suit 200 of embodiment 11, Fig. 24B is a schematic back view of the cooling suit 200 of embodiment 11, and Fig. 25 is a schematic view of the cooling suit 200 of embodiment 11 in an unfolded state. The cooling suit 200 of embodiment 11 is configured such that the intermediate layer 31 of the front fabric 2 covers only the thorax, rather than covering the abdomen and thorax, which are the upper half of the body, as in Fig. 20. The back fabric 3 covers the waist and back, as in Fig. 21.

[0116] 25 , the front fabric 2 and the back fabric 3 of the cooling suit 200 are continuous, with no joint between them. Specifically, the front layer 30, the moisture permeation control layer 33, the intermediate layer 31, and the inner layer 32 are each made of a single piece of material, and when a person puts on the cooling suit 200, the front layer 30, the moisture permeation control layer 33, the intermediate layer 31, and the inner layer 32 each bend at the shoulders. In the cooling suit 200 of embodiment 11, the fabric on the front side of the body (left side of the drawing) from the shoulders (broken line) is defined as the front fabric 2, and the fabric on the back side of the body (right side of the drawing) from the shoulders is defined as the back fabric 3.

[0117] As shown in Fig. 24A, the outer fabric 2 of embodiment 11 covers the thorax. Two meshes are provided on the left and right sides of the lower side of the outer fabric 2 to cover the abdomen. Mesh pockets 215 are provided on the outside of each of the two meshes so that items can be placed inside. The pockets 215 can be opened and closed using Velcro (registered trademark) provided at the top of the inside of the pockets 215.

[0118] 24B , the lining fabric 3 of embodiment 11 covers the waist and back. A water inlet 20 is provided on the upper side of the lining fabric 3, and a cap-type drain outlet 22 is provided on the lower side of the lining fabric 3.

[0119] The back fabric 3 has a first obliquely pressed portion 11A1 and a second obliquely pressed portion 11A2 disposed between the water inlet 20 and the drain outlet 22 in the direction of the center line 92. The first obliquely pressed portion 11A1 and the second obliquely pressed portion 11A2 are disposed symmetrically with respect to the center line 92 and are inclined obliquely downward with respect to a horizontal line perpendicular to the center line 92. A gap 12 is provided around the first obliquely pressed portion 11A1 and the second obliquely pressed portion 11A2. When water is supplied to the intermediate layer 31 from the water inlet 20, the water supplied to the intermediate layer 31 moves downward due to gravity. The water in the intermediate layer 31 that has moved downward comes into contact with the first obliquely pressed portion 11A1 and the second obliquely pressed portion 11A2 and moves obliquely downward along the first obliquely pressed portion 11A1 and the second obliquely pressed portion 11A2. Water in the intermediate layer 31 moves downward from the gap 12 between the lower end of the first inclined pressure-bonding portion 11A1 and the pressure-bonding portion 11 and the gap 12 between the lower end of the second inclined pressure-bonding portion 11A2 and the pressure-bonding portion 11.

[0120] As a result, the first inclined pressure-bonding portion 11A1 and the second inclined pressure-bonding portion 11A2 can prevent the water in the intermediate layer 31 from moving vertically downward due to gravity. As a result, the water in the intermediate layer 31 can move diagonally downward and can be retained in the intermediate layer 31 for a long time, thereby allowing the body to be cooled for a long time.

[0121] The first inclined crimping portion 11A1 and the second inclined crimping portion 11A2 are not connected but separated, and an intermediate layer 31 is provided between the first inclined crimping portion 11A1 and the second inclined crimping portion 11A2. Water moves downward from the intermediate layer 31, so that water can be distributed throughout the entire intermediate layer 31 below the first inclined crimping portion 11A1 and the second inclined crimping portion 11A2. The water in the intermediate layer 31 below the first inclined crimping portion 11A1 and the second inclined crimping portion 11A2 is not subjected to pressure from above, and is therefore less likely to move downward.

[0122] According to the above-described embodiment, the front layer 30, the moisture permeation control layer 33, the intermediate layer 31, and the inner layer 32 of the front fabric 2 and the back fabric 3 are each made of a single piece of material, so there are no joints in the shoulders of the cooling suit 200. As a result, the joints do not peel off, and water in the intermediate layer 31 is prevented from leaking out through the joints. The cooling suit 200 may also have the configurations shown in Figures 9A, 9B, 10A, and 10B.

[0123] (Embodiment 12) In embodiment 12, water passages 230 are provided in the shoulder portions of the cooling suit 200 of Fig. 25. Fig. 26A is a schematic diagram of the front fabric 2 and back fabric 3 of the cooling suit 250 of embodiment 12 in an unfolded state, and Fig. 26B is a schematic cross-sectional view taken along the line D-D of Fig. 26A. Although not shown in Fig. 26B, the back fabric 3 is provided with the water inlet 20 and drain outlet 22 of Fig. 24B.

[0124] As shown in Figure 26A, one or more rectangular water passages 230 (dashed line portions) indicated by dashed lines are provided in the shoulder portion (cross section D-D) of the cooling suit 250 (four water passages 230 are provided in Figure 26A). As shown in Figure 26B, the cross section of the water passage 230 is also rectangular. The water passage 230 is a space in the shoulder portion of the cooling suit 250 where the intermediate layer 31 has been removed. The shape of the water passage 230 is not limited as long as it allows water to pass through.

[0125] The operation of spreading water over the entire cooling suit 250 will now be described. First, while holding the cooling suit 250 in one's hand, a person supplies water to the intermediate layer 31 from the water inlet 20 of the lining fabric 3. The water supplied to the intermediate layer 31 spreads due to gravity into the intermediate layer 31 below the water inlet 20. Next, the person puts on the cooling suit 250. Finally, the person presses their hand against the lining fabric 3 at the waist and moves the pressed hand upwards on the lining fabric 3 until it reaches the shoulder area.

[0126] According to the above embodiment, when water in the intermediate layer 31 passes through the shoulder area and moves from the intermediate layer 31 of the back fabric 3 to the intermediate layer 31 of the front fabric 2, most of the water in the intermediate layer 31 can pass through the space, the water passage 230. Therefore, the water in the intermediate layer 31 can move smoothly from the intermediate layer 31 of the back fabric 3 to the intermediate layer 31 of the front fabric 2. In particular, when a person is wearing the cooling suit 250, the thickness of the shoulder areas of the cooling suit 250 is narrow, so providing the water passage 230 is effective.

[0127] Although the cooling suit 200 of embodiment 11 has an intermediate layer 31 that covers only the thorax, the intermediate layer 31 may also cover the thorax and abdomen. When a person moves water from the intermediate layer 31 of the lining fabric 3 to the intermediate layer 31 of the front fabric 2, the person may not wear the cooling suit 250 but may place the cooling suit 250 on a desk, table, or the like, with the front fabric 2 and back fabric 3 of the cooling suit 250 spread out, allowing the water to move from the intermediate layer 31 of the lining fabric 3 to the intermediate layer 31 of the front fabric 2. The water passage 230 can also be applied to a configuration in which the front fabric 2 covers the abdomen and thorax, such as the cooling suit 1 of FIG. 1. The cooling suit 250 may also have the configurations shown in FIGS. 9A, 9B, 10A, and 10B.

[0128] It is preferable that all or part of the front fabric 2 and back fabric 3 of the cooling suits 1, 100-103, 200, and 250 of the first to twelfth embodiments be subjected to antibacterial and deodorizing treatment.

[0129] 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.

[0130] In the first embodiment, the front fabric 2 and the back fabric 3 have four layers, namely, the front layer 30, the moisture permeability control layer 33, the intermediate layer 31, and the inner layer 32, but these four layers may be included in only one of the front fabric 2 or the back fabric 3. For example, when the back fabric 3 has these four layers, the back fabric 3 has a pressure-bonded portion 11 around its periphery, the pressure-bonded portion 11 surrounds the intermediate layer 31, and the pressure-bonded portion 11 has these four layers inside. Furthermore, the front fabric 2 is almost entirely made of mesh, and does not have these four layers.

[0131] 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.

[0132] According to the above-described embodiment, since the front fabric 2 or the back fabric 3 is made of mesh, sweat evaporating from the body can be expelled through the mesh, reducing sweat stuffiness. Furthermore, 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 in only one of the front fabric 2 or the back fabric 3, the amount of water injected can be reduced, thereby reducing the weight of the cooling suit 1, 100. The above-described effect is particularly effective during hot seasons such as summer. The front fabric 2 may have these four layers, and almost all of the back fabric 3 may be made of mesh.

[0133] 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 can adjust the length. Alternatively, the left fabric 4 and the right fabric 5 may be made of a non-stretchable material and provided with an adjuster.

[0134] The water inlet 20 or the drain outlet 21 in Fig. 3 may be configured with the cap in Fig. 7. Also, the cap in Fig. 7 may be configured with the water inlet 20 or the drain outlet 21 in Fig. 3.

[0135] In the first embodiment, an antistatic treatment is described in which the material of the inner layer 32 and / or the material of the outer layer 30 is provided with antistatic properties using antistatic yarn or the like. However, the present disclosure may also include the following treatment in which the material of the inner layer 32 and / or the material of the outer layer 30 does not use antistatic yarn or the like. This treatment is a treatment in which a spin tape with antistatic (antistatic) properties is used. The spin tape is a conductive yarn having a conductive material kneaded into its fibers. The spin tape is used by sewing it to the outer surface and / or the inner surface of the garment. The spin tape may also be adhered to the outer surface and / or the inner surface of the garment by adhesive bonding, joining, welding, or the like. Examples of the spin tape that can be used include "STA-GUARD SPIN TAPE" manufactured by Tokai Thermo Co., Ltd. Examples of the spin tape that can be used include "STC60" manufactured by Shindo Corporation.

[0136] The spin tape is provided at any position on the cooling suit, such as the shoulders, sides, or sides of the cooling suit.

[0137] 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. However, the cooling suit 1 may also be layered on top of the following clothing. In this case, the layered clothing is placed on the outside of the cooling suit 1. The clothing in question may be a blouson, jacket, workwear, suit, polo shirt, dress shirt, jumpsuit, white coat (doctor's coat), chef's coat, kimono, firefighter's uniform, or costume. Alternatively, the clothing in question may be placed on the inside of the cooling suit 1, 100, as another layered clothing configuration.

[0138] The above-mentioned inventions of the present application can be replaced or combined as long as no contradiction occurs.
