2. Description of the Related Art Conventionally, in order to cool a body simply,
There are roughly three types of structures to take the heat out of the body. Specifically, a polymer gel pack is attached and the body is deprived of body temperature by applying the cooled polymer gel pack to the body. One that lowers body temperature by removing heat from the body and evaporating it, and one that incorporates a polymer absorber to absorb more water and maintain the cooling effect. Each of these three conventional types can provide a cooling effect, but has mechanical problems. In other words, the cooling feeling cannot be obtained without forcibly cooling the liquid in advance, and the liquid can be dripped at the time of mounting in a short time in which the wet state can be maintained without the trouble of preparation. Regardless of powder or fibrous, regardless of powder or fibrous form, the polymer water-absorbing components will fuse together when absorbing water, losing the air permeability of the cooling body, and the liquid will be agglomerated. Was not very efficient in practice. Furthermore, in the above case, in a situation where it is generally considered effective to use (temperature of 25 ° C. or higher), a completely dry state is not obtained even after 3 hours, which is a problem in use.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a cooling body utilizing heat of vaporization according to the present invention will be described with reference to the drawings.

FIG. 1 shows an example in which a cooling body 1 is formed as a long strip-shaped object, and a water-absorbing polymer fiber absorbent 3 is wrapped in a cloth 2 having a water-conducting effect and / or a transpiration effect.
The fabric 2 is made of a tricot fabric made of a fiber material such as hydrophilic polyester, nylon, or acrylic so as to exhibit a water-conducting effect and / or a transpiration effect. Constitutes a rough surface composed of fine irregularities, contacts with a water-absorbent polymer fiber absorber 3 described later, absorbs water from the absorber 3 by a capillary phenomenon, and makes it easy for water to seep out to the surface of the cooling body. . Needless to say, the fabric 2 may be a water-absorbent knitted fabric such as cotton as long as the same effect as described above can be exerted. In addition, in order to prevent the fabric 2 from being repeatedly immersed in water and dried, and to prevent the generation and proliferation of bacteria or the generation of odor due to the attachment of sweat and secretions from the human body, use of antibacterial fiber? Has antibacterial treatment. The antibacterial fiber is a fiber carrying any or all of an antibacterial, deodorant, and fungicide, and is a polyester,
An antibacterial, deodorant, and fungicidal effect is exerted by adding, for example, a zeolite metal adduct to nylon or acrylic at the stage of producing fibers, or by adding a silicone quaternary ammonium salt-based one in post-processing.

[0008] The water-absorbing polymer fiber absorbent 3 is made of a water-absorbing fiber in the form of a cloth or a non-woven fabric. When the water-absorbing polymer fiber absorbent 3 is formed into a cross-shaped or non-woven fabric, 10-70% of polyester fiber or the like is mixed to maintain the shape.
Increases the efficiency of moisture transfer to the outside. In addition, in order to maintain the strength of the water-absorbing polymer fiber absorber 3, by way of example, a nonwoven fabric of a fibrous polymer absorber which is needled together with a polyester sheet having a basis weight of 10 to 20 g,
The shape-retaining property of the water-absorbing polymer fiber absorber 3 is improved. By mixing antibacterial fibers having any or all of antibacterial, deodorant, and antifungal properties at the time of the cotton mixing, or by subjecting the water absorbent polymer fiber absorber 3 to antibacterial, deodorant, and fungicide treatment, the water absorbent polymer fiber absorption is achieved. The body 3 can also exhibit antibacterial, deodorant and mold-proof properties.

[0009] The cooling body 1 is constructed by wrapping the above-mentioned water-absorbent polymer fiber absorbent 3 with the fabric 2 and sewing 4 the end portion of the fabric 2 and other appropriate places. In the case where the cooling body 1 is a strip-shaped long object, if the cooling body 1 is cut with a welder or the like at an appropriate length, the cut surface is fused, and it is not necessary to perform end processing.

The cooling body 1 can be formed in different shapes depending on the intended use, such as a band-shaped body or a flat plate-shaped body extending in all directions as shown in FIG. 1, and the sliding body, bandana, and collar for a cap body which will be described later. It can be a firewood, a back cover, or a cover used to cool the entire body for medical use.

When the cooling body 1 is used, the water absorbing body 3 absorbs water by immersing the cooling body 1 in water or the like. The water taken into the water-absorbent polymer fiber absorber 3 is present only while expanding the volume of the water-absorbent polymer fiber absorber 3 itself and keeping the shape as cotton by the mixed polyester fiber. . For this,
The surface area of the water-absorbent polymer fiber absorber 3 containing water is enlarged, and the water taken in is evaporated smoothly. Furthermore, a capillary phenomenon occurs in a portion in contact with the surrounding fabric 2, and water is guided to the outer shell of the cooling body 1 and evaporates from the fabric 2. Then, the temperature of the water of the part of the cooling body 1 that comes into contact with the body part rises due to the heat of the body and evaporates through the gaps between the fibers. The air cooled by the heat of vaporization lowers the body temperature.

Next, an embodiment in which the cooling body 1 is used as a cap body slipper 11 is shown in FIG.

At the lower edge portion of the cap body 12, a cooling body 1 formed in a strip shape is provided. The cooling body 1 may be provided as shown in FIG. 2A over the entire periphery of the lower edge except for the notch 15 in the back of the head of the cap body 12, or may be provided only on the forehead portion as shown in FIG. 2B. Is also good. The cap body 12 is made of, for example, cotton or rayon made of a fiber having hydrophilicity, and smoothly guides the water inside the slip, and vaporizes the fluid by widely moistening the surface of the cap body. I have to.

Numeral 13 denotes a collar for housing a core 14, which is sewn integrally with the cap body 12. Bands 16 are provided on both sides of the notch 15 on the back of the cap 12 so that the circumference of the cap can be adjusted by a buckle or the like (not shown).

The sliding member 11 is a cap body 1 having a collar 14.
2 shows an example, but the present invention is not limited to this example, and can be used for, for example, a covering object such as a helmet or a sword cap. In order for the cooling body 1 attached to the cap body 12 to exert a cooling effect, the cap body 12 is immersed in water and the cooling body 1 absorbs water.
When the cap body 12 is worn, the water of the water-absorbing polymer fiber absorber 3 is discharged to the surface of the cooling body 1 by the capillary action of the minute uneven surface on the inner surface of the tricot as in the cooling action of the cooling body 1 described above. Then, it diffuses into the cloth of the cap body 12 integrated with the surface of the cooling body 1 and evaporates from the cap body surface. Then, the temperature of the head in contact with the slip 11 rises due to the water guided to the head contacting the head, and the water evaporates through the gaps between the fibers.
The temperature of the head is lowered by the air cooled by the heat of vaporization.

As described above, the cooling body 1 of the present invention is made by mixing the water-absorbing polymer fiber absorber 3 and the polyester fiber into a lump when absorbing water unlike the case of using only the water-absorbing polymer fiber absorber 3. Therefore, the water moves inside the water-absorbing polymer fiber absorber 3 so that the entire fiber can maintain a uniform moisture content, and the gap between the fibers inside the water-absorbing polymer fiber absorber 3 is secured. By the inflow of air from the part,
And the circulation of discharge is secured, and extremely efficient cooling is performed. The greater the water-conducting or diffusing effect, the greater the cooling effect.

Table 1 shows the results of the measurement of the effect of the cap provided with the slip according to the present invention.

[0018]

[Table 1]

For the measurement, a 4 cm wide band-like trapezoid, for example, having a side length of 23
cm and a cooling body obtained by cutting the both ends obliquely so as to have a length of 20 cm on the other side was used. Of course, a rectangular shape may be used instead of a trapezoidal shape. The measurement was performed at room temperature of 22 degrees Celsius.
Degree. The measuring method is as follows. Immerse the cap in water for 15 minutes. Dehydrate for 15 minutes by the vertical drop method. The subject wears the cap and measures the temperature of the forehead surface (at the portion in contact with the cooling body) after 10 minutes. After one measurement, the subject is kept in a natural state for at least 20 minutes before the next measurement. At the start of the measurement, the temperature of the subject's head (naked forehead) was about 0.3 degrees Celsius around 34 degrees Celsius. FIG. 3 is a graph of the results of Table 1. The measurement of the head was repeated seven times for each material, and the measured value of the cooled head temperature was shown on the right side of the vertical axis (or multiple points if there were multiple same values), and the average value was shown on the left side of the vertical axis. Indicates temperature. It is clear that the one using the tricot for the outer layer of the cooling body is particularly excellent.

[0020]

The cooling body of the present invention has the following effects. Inside the cooling body, water moves and the entire fiber maintains a uniform moisture content, so that a uniform cooling effect can be obtained throughout,
In addition, a gap between the fibers inside the cooling body is ensured, and the inflow of air from the outside and the flow of discharge of the air to the outside are good, and effective cooling can be performed. The slip of the present invention has the following effects. In the present invention, since the cooling body is directly attached to the lower edge of the cap body, the cooling body is always provided in a portion in contact with the skin, and the surface of the cooling body is always in any way. It is in contact with the skin, further enhancing the cooling effect. Furthermore, since the volume of the water absorbing body can be smaller than that of the conventional structure, it is possible to reduce the weight of the cap body at the time of water absorption, which prevents mental concentration when performing sports that require concentration. 1 which is the limit value of the cap body weight
It is much less than 80 g and can be used with the same feeling as a normal general cap. By adopting the above structure, the area of the water absorption part is reduced compared to the conventional cooling body,
The time required for the cooling body to reach a sufficiently dry state depending on the body temperature can be reduced. Since the cotton and the nonwoven fabric of the cooling body and the cloth wrapping them are treated with antibacterial treatment, the growth of bacteria can be suppressed by repeated use and immersion in water.
