Description

Multilayer fabric and covering

[0001] The present invention relates to a multilayer fabric and a covering.

[0002] Among conventional coverings, there are some in which when the phase change material in the microcapsules is warmed by body temperature and melts, an endothermic reaction occurs and heat transfer from the skin to the fabric causes a cooling sensation (see, for example, Patent Documents 1 and 2 below).

[0003] Utility Model Registration No. 3185616, JP-A-2024-119893

[0004] In the prior art including Patent Documents 1 and 2, microcapsules, gel-like substances, and other cooling materials are used, but the situation is that they are not sufficient to solve summer sleep problems. That is, it was not sufficient to solve sleep problems such as having difficulty falling asleep due to heat and humidity on summer nights, or waking up in the middle of the night due to the cold from air conditioning.

[0005] The present invention has been made in view of such a situation, and an object thereof is to provide a multilayer fabric and a covering that can solve summer sleep problems.

[0006] To achieve the above object, a multilayer fabric according to one aspect of the present invention is a multilayer fabric that covers at least a part of a person as a target part, and includes a first layer that touches the target part, and a second layer that is disposed on the opposite side of the first layer from the target part and absorbs moisture from the target part. The second layer has a cotton body and a moisture absorption part provided on at least one surface of the cotton body.

[0007] Further, to achieve the above object, a covering according to one aspect of the present invention is a covering that covers a target part, made using a multilayer fabric that covers at least a part of a person as the target part, and includes a first layer that touches the target part, and a second layer that is disposed on the opposite side of the first layer from the target part and absorbs moisture from the target part. The second layer has a cotton body and a moisture absorption part provided on at least one surface of the cotton body.

[0008] According to the present invention, it is possible to provide multilayer fabrics and coverings that can solve the problem of sleeping in the summer.

Figure 1 shows the effects of the comforter and mattress pad, where (a) shows the effect on sleep duration, (b) shows the effect on moisture absorption, (c) shows how the inside of the bedding warms up in an air-conditioned room, and (d) shows how the inside of the bedding warms up in a hot room.

[0010] Embodiments of the present invention will be described below with reference to the drawings.

[0011] Figure 1 shows an example of a covering made using a multilayer fabric according to one embodiment of the present invention, where (a) is a perspective view showing a comforter placed on a mattress pad, and (b) is a perspective view showing a mattress pad attached to a mattress. For illustrative purposes, arrow P in Figure 1 indicates, for example, the up and down direction. Also, arrow Q indicates, for example, the front and back direction. Furthermore, arrow R indicates the left and right direction.

[0012] One example of a covering is the comforter 1, which is made using a multi-layered fabric that covers a person's body from the neck down (shoulders, chest, abdomen, waist, legs, etc.). Another example of a covering is the mattress pad 2, which is made using a multi-layered fabric that is attached to a mattress 3, for example, and covers the aforementioned body parts from below when a person lies down on it. Both the comforter 1 and the mattress pad 2 have the function of lowering the perceived temperature and are designed to solve the summer sleep problem of difficulty falling asleep due to the heat and stuffiness of summer nights. Furthermore, both the comforter 1 and the mattress pad 2 have the function of conditioning the bed to an "just right" ideal environment and are designed to solve the summer sleep problem of waking up in the middle of the night due to the cold from air conditioning.

[0013] First, let's explain the comforter 1. In addition to Figure 1 mentioned above, please also refer to Figures 2 and 3. Figure 2 is a perspective view of the comforter shown in Figure 1(a). Figure 3 is a diagram relating to the comforter shown in Figure 1(a), where (a) is a diagram of the structure of the multilayer fabric used in the comforter, and (b) is a cross-sectional view taken along line A-A in (a).

[0014] Duvet 1 has the function of lowering the perceived temperature (lowering humidity) and the function of creating an ideal temperature and humidity environment in the bed. By using Duvet 1, it is possible to alleviate the difficulty of falling asleep on summer nights due to heat and stuffiness, and the problem of waking up in the middle of the night due to the cold from air conditioning. Duvet 1 functions to condition the bed environment to the "just right" ideal state through the use of multi-layered fabric.

[0015] The "ideal temperature environment" mentioned above is, for example, an environment where the temperature inside the bed is "33°C ± 1°C" (the numerical value is just an example). Similarly, the "ideal humidity environment" mentioned above is, for example, an environment where the humidity inside the bed is "50% ± 5% RH" (the numerical value is just an example).

[0016] Duvet 1 not only lowers the perceived temperature, but also creates a temperature environment of "33°C ± 1°C" and a humidity environment of "50% ± 5% RH" within the bed. By conditioning the bed to the aforementioned "just right" ideal environment, it can eliminate problems such as difficulty falling asleep due to heat and stuffiness on summer nights, or waking up in the middle of the night due to the cold from air conditioning.

[0017] Lowering the perceived temperature will be discussed later, but here we will explain how to condition yourself to the ideal "just right" sleeping environment mentioned above. Duvet 1 is designed to help lower a person's core body temperature. Specifically, Duvet 1 creates a temperature environment of "33°C ± 1°C" and a humidity environment of "50% ± 5% RH" within the bed, thereby promoting heat dissipation from the extremities such as fingertips, palms, and toes, and contributing to lowering a person's core body temperature.

[0018] The comforter 1 contributes to lowering a person's core body temperature, which in turn shortens the time it takes to fall asleep and can lead to an increase in sleep duration (the increase in sleep duration will be discussed later with reference to Figure 6).

[0019] The temperature at which the bedding reaches "33°C ± 1°C" and the humidity at which the bedding reaches "50% ± 5% RH" are values ​​obtained through various experiments (the above temperature and humidity can be set as guidelines).

[0020] Because comforter 1 is thin and has no thickness, it is easy to fold and store. Furthermore, because comforter 1 is so thin, it can be easily washed in a washing machine. Also, because comforter 1 is thin and has no thickness, it feels lighter during sleep, allowing for a more comfortable night's rest.

[0021] As described above, comforter 1 can create a humidity environment in the bed where the humidity is "50% ± 5% RH", and as a result, it can provide a comfortable sleeping experience without stuffiness. Furthermore, comforter 1, as a multi-layered fabric, includes a second layer 12 having a moisture-absorbing section 122, which will be described later, and as a result, it can lower the perceived temperature, contributing to a comfortable sleeping experience without stuffiness.

[0022] The structure of the comforter 1 will now be described. The comforter 1 is composed of an inner knitted fabric layer 11, a temperature-regulating cotton layer 12, a soft cotton layer 13, and an outer knitted fabric layer 14. In this embodiment, the comforter 1 is configured to have a four-layer structure in the vertical direction indicated by arrow P (four layers is just one example).

[0023] To prevent the cotton filling from shifting, as described later, the comforter 1 is fitted with an arc-shaped quilting pattern (this is just one example) as shown in Figure 2. In this embodiment, the comforter 1 is available in four sizes: single, semi-double, double, and queen (dimensions are omitted).

[0024] If the area covered by the comforter 1 is, for example, from the neck down, then the inner knit fabric layer 11 is provided as a layer that touches the target areas such as the shoulders, chest, abdomen, waist, and legs. The inner knit fabric layer 11 is the layer closest to the target area (it is the inner layer). The inner knit fabric layer 11 is not particularly limited, but in this embodiment, a fabric made of a contact-cooling material (a fabric that feels cool to the touch) is used. Examples of contact-cooling materials include polyester, rayon, silk, linen, etc., and here, a material with a smooth texture is preferred (a material with a refreshing and smooth texture that makes you want to rub your cheek against it is preferred. In addition, for example, a slightly brushed knit layer with a silky touch texture may also be used). In this embodiment, the inner knit fabric layer 11 is manufactured to weigh 170 g / m2 (the value is an estimate).

[0025] The temperature-regulating batting layer 12 is positioned on the opposite side of the target area from the inner knitted fabric layer 11. That is, the temperature-regulating batting layer 12 is positioned outside the inner knitted fabric layer 11 relative to the target area. The temperature-regulating batting layer 12 is the batting layer. The temperature-regulating batting layer 12 is the third layer positioned from the side of the target area (the second layer will be described later).

[0026] The temperature-regulating cotton layer 12 has a cotton body 121 and a moisture-absorbing portion 122 provided on at least one surface of the cotton body 121 (in this embodiment, the moisture-absorbing portion 122 is located on the surface closer to the target portion mentioned above).

[0027] The cotton body 121 is provided as a layer to regulate the temperature of the space (internal bedding environment) between the inner knit fabric layer 11 and the aforementioned target area. The reason why "wata" is used instead of "wata" which refers to cotton is because "wata" is a general term for things in which fibers are intertwined and form a mass.

[0028] The cotton body 121 is composed of temperature-regulating fibers that can adjust the temperature within a predetermined range when a person touches the target area described above, and one or more short fibers different from the temperature-regulating fibers, which are blended with the temperature-regulating fibers. The cotton body 121 is formed in a state in which the temperature-regulating fibers and the blending short fibers are intertwined. The cotton body 121 is formed in a sheet shape (for example, it may be formed in a granular cotton shape). In this embodiment, the cotton body 121 is manufactured to be 100 g / m2 (20% 2.3D temperature-regulating fibers + 80% polyester) (the value is an estimate). In this embodiment, "THERMO FLEX®" is used as the temperature-regulating fiber (this is just one example). The temperature-regulating fiber is preferably made of a material that has the function of repeatedly releasing and absorbing heat to regulate temperature, and is capable of controlling thermal energy by changing from liquid to solid and from solid to liquid.

[0029] The short fibers used for blending, as described above, are selected to provide bulkiness, heat retention, resistance to clumping, washability (quick drying), and softness when combined with temperature-regulating fibers.

[0030] Regarding the above combinations, blending relatively thick, hollow short fibers can contribute to bulkiness, heat retention, and resistance to clumping. Similarly, blending relatively thin, hollow short fibers can also contribute to heat retention and resistance to clumping.

[0031] Furthermore, blending solid, relatively thick short fibers can contribute to bulkiness, washability (quick drying), etc. Conversely, blending solid, relatively thin short fibers can contribute to softness, etc.

[0032] The moisture-absorbing portion 122 is formed in a part that absorbs moisture from the target area as described above, thereby lowering the perceived temperature. The moisture-absorbing portion 122 is obtained by processing silica gel (Type B silica gel). Specifically, the moisture-absorbing portion 122 is formed in a part obtained by applying a mixed solvent 122c (described later with reference to Figure 5) containing silica gel to one of the surfaces of the cotton body 121 (the surface facing the target area). The moisture-absorbing portion 122 is formed so that one surface of the cotton body 121 becomes a moisture-absorbing portion, i.e., a moisture-absorbing portion. The moisture-absorbing portion 122 is a part that can give the temperature-regulating cotton layer 12 high hygroscopicity. In this embodiment, the moisture-absorbing portion 122 is formed to be 40 g / m2 (Type B silica gel) (the value is an estimate). An example of the detailed formation process of the moisture-absorbing portion 122 will be described later with reference to Figure 5. As will be explained later, the "processing of silica gel (Type B silica gel)" does not refer to a stuffing process such as filling a futon with silica gel (Type B silica gel). More specifically, it does not refer to a process that results in a structure and configuration such as sandwiching silica gel (Type B silica gel) between needle-punched nonwoven fabric (such a process would result in a hard, plate-like material. Therefore, it would be difficult to ensure high drapeability and flexibility as a futon. The moisture-absorbing part 122 is obtained through a forming process described later, and since it does not become a silica gel (Type B silica gel) filling, it naturally ensures high drapeability and flexibility).

[0033] The soft cotton layer 13 is provided as a layer positioned between the inner knit fabric layer 11 and the temperature-regulating cotton layer 12. The soft cotton layer 13 is positioned as the second layer from the side of the target area.

[0034] The soft cotton layer 13 is made of soft, highly absorbent cotton (for example, 100% natural cotton) and is formed, for example, into a sheet. In this embodiment, the soft cotton layer 13 is manufactured to have a density of 50 g / m2 (this value is an estimate). The soft cotton layer 13 is provided to give the comforter 1, for example, a fluffy feel. The soft cotton layer 13 is a second cotton body separate from the cotton body 121 described above.

[0035] The outer knitted fabric layer 14 is positioned outside the temperature-regulating cotton layer 12 relative to the target area. The outer knitted fabric layer 14 is positioned as the fourth layer from the side of the target area. In this embodiment, the outer knitted fabric layer 14 is manufactured in the same way as the inner knitted fabric layer 11 (therefore, a detailed explanation is omitted).

[0036] As explained above with reference to Figures 1 to 3, comforter 1, an example of a covering made using multi-layered fabric, can lower the perceived temperature by reducing humidity. Furthermore, by achieving a temperature environment of "33°C ± 1°C" and a humidity environment of "50% ± 5% RH" inside the bedding, it can condition the bedding to an "ideal" environment. As a result, it can alleviate problems such as difficulty falling asleep due to heat and stuffiness on summer nights, or waking up in the middle of the night due to the cold from air conditioning.

[0037] Next, with reference to Figures 1 and 4, a mattress pad 2 will be described as another example of a covering made using multilayer fabric. Figure 4 is a diagram relating to the mattress pad of Figure 1(b), where (a) is a diagram of the multilayer fabric used in the mattress pad, and (b) is a cross-sectional view taken along line B-B in (a).

[0038] The mattress pad 2, like the comforter 1 described above, has the function of lowering the perceived temperature (lowering humidity) and the function of creating an ideal temperature and humidity environment within the bedding. By using the mattress pad 2 in conjunction with the comforter 1, for example, it can help alleviate problems such as difficulty falling asleep due to heat and stuffiness on summer nights, or waking up in the middle of the night due to the cold from air conditioning. The mattress pad 2 functions to condition the bedding environment to an "just right" ideal state through the use of its multi-layered fabric. In this embodiment, the mattress pad 2 adopts the structure of the comforter 1, effectively transforming the comforter 1 into a mattress pad. Therefore, the effects obtained from the mattress pad 2 are basically the same as those of the comforter 1.

[0039] The mattress pad 2 is composed of a front fabric layer 21, a temperature-regulating cotton layer 22, a soft cotton layer 23, and a back fabric layer 24. In this embodiment, the mattress pad 2 is configured to have a four-layer structure in the vertical direction indicated by arrow P (four layers is just one example).

[0040] To prevent the filling from shifting, the mattress pad 2 is quilted with intersecting diagonal stripes, as shown in Figure 1 (this is just one example). Like the comforter 1, the mattress pad 2 is available in four sizes: single, semi-double, double, and queen (dimensions are omitted).

[0041] The outer fabric layer 21 is provided as a layer that comes into contact with the person lying on the mattress pad 2. The outer fabric layer 21 is the layer closest to the aforementioned target area (it is the outer layer of the mattress pad 2). The outer fabric layer 21 uses basically the same material as the inner knit fabric layer 11 (the outer fabric layer 21 may also be called the outer knit fabric layer). The outer fabric layer 21 is manufactured to weigh 170 g / m2, the same as the inner knit fabric layer 11 (the value is an estimate). A detailed explanation of the outer fabric layer 21 is omitted.

[0042] The temperature-regulating cotton layer 22 has the same configuration as the temperature-regulating cotton layer 12 of the futon 1. That is, the temperature-regulating cotton layer 22 has a cotton main body 221 and a moisture absorption part 222 provided on at least one surface of the cotton main body 221 (in this embodiment, the moisture absorption part 222 is arranged on the surface closer to the above-mentioned target part). The cotton main body 221 and the moisture absorption part 222 basically adopt the same materials as the cotton main body 121 and the moisture absorption part 122 of the futon 1, and the detailed description is omitted here.

[0043] In this embodiment, the cotton main body 221 is manufactured to be 50 g / m2 (15% of temperature-regulating fiber of 6.7 D + 85% of polyester) (the numerical value is for reference). In this embodiment, the moisture absorption part 222 is formed to be the same as the moisture absorption part 122 of the futon 1, which is 40 g / m2 (type B silica gel) (the numerical value is for reference). For an example of the detailed formation of the moisture absorption part 222, it will be described later with reference to FIG. 5. The temperature-regulating cotton layer 22 is arranged at a position (on the back side) farther from the front fabric layer 21 with respect to the target part. The temperature-regulating cotton layer 22 becomes the middle cotton layer. The temperature-regulating cotton layer 22 is the third layer counted from the side of the target part.

[0044] The soft cotton layer 23 is the same as the soft cotton layer 13 of the futon 1, and the detailed description is omitted. In this embodiment, the soft cotton layer 23 is manufactured to be 50 g / m2, the same as the soft cotton layer 13 of the futon 1 (the numerical value is for reference).

[0045] The back fabric layer 24 is arranged to be the fourth layer counted from the side of the target part. The back fabric layer 24 is a layer that contacts the mattress 3 and is not particularly limited. For example, it is manufactured from spring sub-weft fabric.

[0046] As described above while referring to FIGS. 1 and 4, the laying pad 2, which is another example of the covering product made using the multilayer fabric, has the same configuration as the futon 1. Therefore, for example, by using it in combination with the futon 1, it can contribute to solving problems such as having difficulty falling asleep due to heat and stuffiness on a summer night or waking up in the middle of the night due to the cold from air conditioning.

[0047] Next, an example of the forming process of the moisture absorption part 122 (222) described above will be described while referring to FIG. 5. FIG. 5 is a diagram of the forming process of the moisture absorption part in the multilayer fabric of FIGS. 3 and 4, where (a) is a diagram showing the first step, (b) is a diagram showing the second step, (c) is a diagram showing the third step, and (d) is a diagram showing the fourth step.

[0048] In FIG. 5, the above-mentioned moisture absorption part 122 (222) is formed through the following first to fourth steps in order, for example. In the first step, B-type silica gel, a foaming agent, and an adhesive are put into a predetermined container 41 and mixed. Although not particularly limited, B-type silica gel in the form of powder with a particle size of 5 μm to 20 μm is adopted. The amount of B-type silica gel is, for example, 20% of the total amount. Also, for example, Isopentane is adopted as the foaming agent. The amount of the foaming agent is, for example, 1% of the total amount. Also, for example, acrylic polymer is adopted as the adhesive. The amount of the adhesive is, for example, 79% of the total amount. The reference numeral 122a (222a) in the first step indicates the solvent after mixing.

[0049] In the second step, the solvent 122a (222a) after mixing in the first step is heated to, for example, 80 degrees (see reference numeral 43. The heating time is, for example, 60 minutes) and stirred (see reference numeral 42) so as not to solidify. The reference numeral 122b (222b) in the second step indicates the solvent after mixing that has been heated and stirred.

[0050] In the third step, the mixed solvent 122b (222b) that was heated and stirred in the second step is placed in the spray equipment 44, and then, for example, the solvent is atomized by high-speed rotation and sprayed onto one side of the unprocessed cotton body 121a to adhere to it. Since the solvent is in atomized form, it penetrates into the cotton through one side. This allows the 5 μm to 20 μm type B silica gel to remain inside the cotton and exert its effect for a long period of time. In the third step, reference numeral 122c (222c) indicates the mixed solvent that has been atomized and adhered. Reference numeral 12a (22a) indicates the temperature-controlled cotton layer with the mixed solvent 122c (222c) adhered to it.

[0051] In the fourth step, the mixed solvent 122c (222c) that was applied in the third step is dried in a dryer 45 (for example, in the range of 120 to 160 degrees Celsius). Reference numeral 12b (22b) in the fourth step indicates the temperature-controlled cotton layer in the state where the mixed solvent 122c (222c) has dried (the state in which the moisture absorption portion 122 (222) has been formed).

[0052] Next, the effects (experimental results) of the comforter 1 and mattress pad 2 will be explained with reference to Figure 6. Figure 6 is a diagram showing the effects of the comforter and mattress pad shown in Figure 1, where (a) shows the effect on sleep time, (b) shows the effect on moisture absorption, (c) shows how the inside of the futon warms up in a room cooled by air conditioning, and (d) shows how the inside of the futon warms up in a hot room.

[0053] As shown in Figure 6(a), using comforter 1 resulted in longer sleep duration compared to using a regular comforter. This indicates that the difficulty in falling asleep due to heat and stuffiness was eliminated, leading to longer sleep duration. Furthermore, as shown in Figure 6(b), comforter 1 was found to have approximately nine times higher moisture absorption than a regular comforter. This is due to the formation of moisture-absorbing sections 122 (222).

[0054] Furthermore, as shown in Figure 6(c), the results showed that after 30 minutes of use in an air-conditioned room, the comforter 1 and mattress pad 2 warmed up more than a typical towel blanket and mattress pad. This indicates that in a "cold" environment cooled by air conditioning, the heat retention function (temperature control function) makes it "less likely" for the inside of the bedding to cool down. Also, as shown in Figure 6(d), the results showed that after 30 minutes of use in a hot room, the comforter 1 and mattress pad 2 warmed up less than a typical towel blanket and mattress pad. This indicates that in a "hot" environment such as a tropical night, the inside of the bedding "does not get hot easily".

[0055] As described above with reference to Figures 1 to 6, the present invention is not limited to the embodiments described above. Furthermore, the effects described in these embodiments are merely a list of the most preferred effects arising from the present invention, and the effects of the present invention are not limited to those described in these embodiments.

[0056] In this embodiment, when forming the moisture-absorbing portion 122 (222), powdered type B silica gel of 5 μm to 20 μm was mixed and then attached to the cotton so that it remained inside, but this is not limited to this. The attachment of type B silica gel may be to fabrics other than cotton, or to other filling materials other than those mentioned above (resin cotton, batted cotton, mixed cotton).

[0057] In this embodiment, a comforter 1 and a mattress pad 2 were described as examples of coverings made using multilayer fabric, but this is not limited to them. That is, the above configuration and structure can also be applied to pajamas, etc. In this embodiment, the mattress pad 2 was attached to the mattress 3, but this is not limited to them. That is, a futon may also be used.

[0058] The multilayer fabrics and coverings to which the present invention applies only need to have the following configuration, and can take on various forms.

[0059] That is, the multilayer fabric to which the present invention is applied (for example, the multilayer fabric for making the comforter 1 and mattress pad 2 shown in Figures 1 to 4) is a multilayer fabric that covers at least a part of a person as the target area (for example, the part below the neck (shoulders, chest, abdomen, waist, legs, etc.)), and comprises: a first layer that touches the target area (for example, the inner knit fabric layer 11 in Figure 3 (for example, the outer fabric layer 21 in Figure 4)); and a second layer that is positioned on the opposite side of the target area from the first layer and absorbs moisture from the target area (for example, the temperature-regulating cotton layer 12 in Figure 3 (for example, the temperature-regulating cotton layer 22 in Figure 4)), wherein the second layer only needs to have a cotton body (for example, the cotton body 121 in Figure 3 (for example, the cotton body 221 in Figure 4)) and a moisture-absorbing part (for example, the moisture-absorbing part 122 in Figure 3 (for example, the moisture-absorbing part 222 in Figure 4)) provided on at least one side of the cotton body. Such multi-layered fabrics can solve the problem of sleeping in the summer.

[0060] Furthermore, in multilayer fabrics to which the present invention is applied (for example, multilayer fabrics for making the comforter 1 and mattress pad 2 shown in Figures 1 to 4), it is preferable that the moisture-absorbing portion is located on the side of the target portion.

[0061] Furthermore, in multilayer fabrics to which the present invention is applied (for example, multilayer fabrics for making the comforter 1 and mattress pad 2 shown in Figures 1 to 4), it is preferable that the moisture-absorbing portion is formed by processing silica gel (for example, the above-mentioned 5 μm to 20 μm powdered type B silica gel).

[0062] Furthermore, it is preferable that the multilayer fabric to which the present invention is applied (for example, the multilayer fabric for making the comforter 1 and mattress pad 2 shown in Figures 1 to 4) further comprises a third layer between the first layer and the second layer, which is made of a second cotton body (for example, the natural cotton mentioned above) separate from the cotton body (for example, the soft cotton layer 13 in Figure 3 (for example, the soft cotton layer 23 in Figure 4)).

[0063] The coverings to which the present invention applies (for example, the comforter 1 and mattress pad 2 shown in Figures 1 to 4) are made using a multilayer fabric (for example, the multilayer fabric used to make the comforter 1 and mattress pad 2 shown in Figures 1 to 4) to cover at least a part of a person as the target area (for example, the part from the neck down (shoulders, chest, abdomen, waist, legs, etc.) as described above), and the coverings that cover the target area include: a first layer that comes into contact with the target area (for example, the inner knit fabric layer 11 in Figure 3 (for example, the outer fabric layer 21 in Figure 4)); and a second layer that is positioned on the opposite side of the target area from the first layer and absorbs moisture from the target area (for example, the temperature-regulating cotton layer 12 in Figure 3 (for example, the temperature-regulating cotton layer 22 in Figure 4)). The second layer only needs to have a cotton body (for example, cotton body 121 in Figure 3 (cotton body 221 in Figure 4, etc.)) and a moisture-absorbing portion provided on at least one surface of the cotton body (for example, moisture-absorbing portion 122 in Figure 3 (moisture-absorbing portion 222 in Figure 4, etc.)). Such a covering can solve the problem of sleeping in the summer.

[0064] Furthermore, it is preferable that the covering product to which the present invention is applied (for example, the comforter 1 and mattress pad 2 shown in Figures 1 to 4) is a comforter that covers the target area when the person sleeps (for example, the comforter 1 shown in Figures 1 to 3), or a mattress pad that is placed under the target area (for example, the mattress pad 2 shown in Figures 1 and 4).
