本発明は吸湿体、特に特定の包装材に包装され
た健康用具として有用な就寝環境を改善する人体
用の吸湿体に係るものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a hygroscopic body, particularly a hygroscopic body for the human body that improves the sleeping environment and is useful as a health tool packaged in a specific packaging material.
（従来の技術）
各種の吸湿剤を包装材により包装した吸湿体は
例えば海苔や菓子類の乾燥剤として種々のものが
知られている。これらの吸湿剤の代表的なものと
してシリカゲルが知られ、特に安全であり、安値
であること等から多く用いられている。(Prior Art) Various types of hygroscopic materials are known, in which various hygroscopic agents are packaged with packaging materials, such as desiccant agents for seaweed and confectionery. Silica gel is known as a representative of these moisture absorbents, and is widely used because it is particularly safe and inexpensive.
更に最近健康機具の流行に乗つてＢ型ゲルを包
装材で包装し、これをシート状にして着物用や人
体の湿気、特に長期間寝たきり老人の湿気による
不快感を和らげようとする提案もなされている。 Furthermore, recently, taking advantage of the trend in health equipment, proposals have been made to package B-type gel in packaging material and make it into a sheet for use in kimonos and to alleviate the discomfort caused by moisture in the human body, especially in elderly people who have been bedridden for long periods of time. ing.
（発明の解決しようにする問題点）
しかしながら、これらの吸湿体は海苔や菓子類
に対しては十分その目的を達成しているものの、
人体用としては初期の吸湿力が必要以上に強く、
吸湿力の持続性がなかつたり、吸湿量が少ない等
使用上多くの問題点がある。(Problems to be Solved by the Invention) However, although these moisture absorbers have sufficiently achieved their purpose for seaweed and confectionery,
The initial hygroscopicity is stronger than necessary for human use.
There are many problems in use, such as lack of sustainability of moisture absorption and small amount of moisture absorption.
（問題点を解決する為の手段）
本発明者はかかる欠点の原因について検討した

止まるものであることに主因のあることが見出さ
れ、更に詳細な検討を進めた処、包装体の透湿性
を或る特定範囲に選ぶことにより、程よい吸湿性
を長期間維持し得ることが見出された。(Means for Solving the Problems) The present inventor has studied the causes of such drawbacks and found that most of the packaging materials constituting moisture absorbers are materials with high moisture permeability such as Japanese paper or nonwoven fabric, or polyethylene sheets. The main reason for this is that the moisture absorbent packed inside does not spill out, and the idea is that it is sufficient to allow air to circulate. After further detailed study, it was discovered that by selecting the moisture permeability of the package within a certain range, it was possible to maintain a suitable level of moisture absorption for a long period of time.
かくして本発明は透湿度が30〜60ｇ／m2・24時
間を有する不織布と、透湿性が実質的にないシー
トとの間に吸湿剤を封入した吸湿体を提供するに
ある。 Thus, the present invention provides a hygroscopic body in which a hygroscopic agent is enclosed between a nonwoven fabric having a moisture permeability of 30 to 60 g/m 2 ·24 hours and a sheet having substantially no moisture permeability.
本発明において用いられる透湿度とは次の様に
定義される。 The moisture permeability used in the present invention is defined as follows.
24時間の乾燥剤の水分吸着量（ｇ）／表側包装剤
の表面積（m2）＝透湿度（ｇ／m2・24時間）
本発明において用いられる不織布は透湿度が30
〜60ｇ／m2・24時間である必要がある。透湿度が
前記範囲に満たない場合には吸湿性を長期間保持
するものの単位時間当りの吸湿性が不足し、逆に
前記範囲を超える場合には吸湿剤が短期間に強力
な吸湿性を示し、長期間にわたり適度な吸湿性を
保持し得ないので何れも不適当である。 Moisture adsorption amount of the desiccant for 24 hours (g)/surface area of the front packaging agent (m 2 ) = moisture permeability (g/m 2・24 hours) The nonwoven fabric used in the present invention has a moisture permeability of 30
~60g/m 2 for 24 hours. If the moisture permeability is less than the above range, the hygroscopicity will be maintained for a long period of time, but the hygroscopicity per unit time will be insufficient; on the other hand, if it exceeds the above range, the hygroscopic agent will exhibit strong hygroscopicity in a short period of time. Both are unsuitable because they cannot maintain adequate hygroscopicity over a long period of time.
そしてこれら範囲のうち透湿度が35〜45ｇ／
m2・24時間を採用する場合には単位時間内の吸湿
性が程良く、又長期間安定して吸湿性を保持し得
るので特に好ましい。 And within these ranges, the moisture permeability is 35 to 45g/
It is particularly preferable to use m 2 ·24 hours because the hygroscopicity within a unit time is moderate and the hygroscopicity can be maintained stably for a long period of time.
この様な不織布が有する透湿度の発現手段とし

ン等熱融着可能なフイルムなら何れも採用出来
る。 Examples of means for developing the moisture permeability of such non-woven fabrics include laminating a perforated polyethylene film onto a non-woven fabric with an adhesive, mechanically or physically perforating a polyethylene film when heat-sealing a non-woven fabric, and using polyethylene. A method such as perforating a laminated nonwoven fabric is employed. As the synthetic resin film to be laminated, any heat-sealable film such as polypropylene can be used.
本発明に用いられる不織布としては通常の市販
品でよいが人体用としては合成樹脂繊維を混抄し
ていないセルローズ系短繊維を圧着した厚手の不
織布が好ましく、バルキー、ソフト感覚を与える
ため目付50〜100のものが特に適当である。 The nonwoven fabric used in the present invention may be any commercially available product, but for use on the human body, it is preferable to use a thick nonwoven fabric made by pressing cellulose short fibers that are not mixed with synthetic resin fibers, and have a basis weight of 50 to 50 to give a bulky and soft feel. 100 is particularly suitable.
本発明において用いられる目付とは次の様に定
義される。 The basis weight used in the present invention is defined as follows.
単位面積当りの重量＝目付（ｇ／m2）
かかる物性を逸脱する場合は透湿度の制御が不
安定となる虞れがあり、人体への感覚も悪く好ま
しくない。 Weight per unit area = basis weight (g/m 2 ) If these physical properties are exceeded, there is a risk that control of moisture permeability may become unstable, and the sensation on the human body may be poor, which is not preferable.

質的にないシートとを例えば重ね合せ、夫々の周
縁部を熱融着する等して袋を形成せしめ、この袋
に吸湿剤を封入せしめるようにする。 In the present invention, such a nonwoven fabric and a sheet with substantially no moisture permeability are stacked, for example, on top of each other, and their peripheral edges are heat-sealed to form a bag, and a moisture absorbent is sealed in this bag. .
ここで用いられる透湿性が実質的にないシート

のもの等が用いられる。 Examples of the sheet with substantially no moisture permeability used here include, for example, a nonwoven fabric laminated with a synthetic resin film, a nonwoven fabric made of a mixture of cellulose staple fibers and synthetic resin fibers, and a synthetic resin film further laminated with the nonwoven fabric. The synthetic resin sheet itself is used.
尚、不織布、特に透湿度が30〜60ｇ／m2・24時
間を有する不織布は、これを例えば適当な撥水処

布を直接通して吸湿剤に達するのを防ぎ、湿気だ
けを通すので好ましい。 In addition, non-woven fabrics, especially non-woven fabrics with a moisture permeability of 30 to 60 g/m 2 24 hours, can be treated with a suitable water repellent treatment to prevent water from directly passing through the non-woven fabric even in the event of incontinence, for example. It is preferable because it prevents moisture from reaching the moisture absorbent and allows only moisture to pass through.
本発明において用いられる吸湿剤としてはシリ
カゲル、アルミナゲル、シリカアルミナゲル、各
種ゼオライトを用いることが出来るが、とりわけ
シリカゲル、それもＡ型のシリカゲルを用いる場
合には就寝時の体表面の湿度70〜80％を60〜70％
に低下させ発汗を抑制する等の効果で就寝環境を
良化する為特に好ましい。 As the moisture absorbent used in the present invention, silica gel, alumina gel, silica alumina gel, and various zeolites can be used, but especially when using silica gel, especially type A silica gel, the humidity of the body surface at the time of sleeping is 70~ 80% to 60-70%
It is particularly preferable because it improves the sleeping environment by reducing sweating and suppressing sweating.
そしてこの場合シリカゲルの物性は湿度50〜80
％で吸水率が少なくとも25％のものが好ましく、
この様な物性を有するＡ型のシリカゲルが最良で
ある。 In this case, the physical properties of silica gel are humidity 50 to 80.
It is preferable that the water absorption rate is at least 25%,
Type A silica gel having such physical properties is best.
更に活性炭、ゼオライト等をこの吸湿剤に２〜
５％程度混合して使用すると吸湿力が向上するの
みでなく脱臭力も加わり好ましい。 Furthermore, activated carbon, zeolite, etc. are added to this moisture absorbent.
It is preferable to use a mixture of about 5%, as this not only improves the moisture absorbing power but also increases the deodorizing power.
かくして得られた吸湿体は通常シーツの下等に
敷いて用いるが、このとき吸湿剤があまり大きな
粒体であると体が痛み、不快感を与える。この
為、平均粒径が0.3〜2.0mm程度の球体を半割り乃
至四つ割りするよう破砕したものを用いると最も
不快感を与えないので好ましい。 The moisture absorbent thus obtained is usually used by placing it under sheets, etc., but if the moisture absorbent is too large particles, it will cause pain and discomfort to the body. For this reason, it is preferable to use spheres with an average particle diameter of about 0.3 to 2.0 mm, which are crushed into halves or quarters, since this will cause the least discomfort.
又、吸湿体全体の大きさは任意に選べるが、寝
床用に用いる場合適当な大きさに区切る方が人の
背中に当る感触の点及び吸湿剤の片寄りを防止し
得るので好ましい。この為一辺を３〜10cmにし、
この袋状体に吸湿剤を１〜20ｇ宛充填するのが適
当である。 Further, the size of the entire moisture absorbent body can be arbitrarily selected, but when used for a bed, it is preferable to divide the moisture absorbent body into appropriate sizes because it prevents the moisture absorbent from being unevenly distributed and the feeling of contact with the back of a person. For this reason, make each side 3 to 10 cm,
It is appropriate to fill this bag-like body with 1 to 20 g of moisture absorbent.
