Description
本発明は、吸湿性及び通水性に優れた敷パッドに関するものである。 The present invention relates to a floor pad excellent in hygroscopicity and water permeability.
周知の通り、人は就寝中に発汗作用により大量の水分を発散しており、これらの水分は敷布団に吸収されるが、湿気を帯びた敷布団は利用者に不快感を与えるので、敷布団を定期的に干す習慣がある。また、不快感のない快適な就寝を保持するために、敷布団の上や下に敷いて該敷布団の湿気を吸収する吸水性を備えたシートが開発されており、例えば、可撓性で透湿性の第１シートと可撓性で透湿性もしくは不透湿性の第２シートとを両面に有してその間に吸水性ポリマーを含有して成る快眠シートが提案されている（特許文献１参照）。 As is well known, people shed a large amount of moisture during sleep, and these moisture is absorbed by the mattress, but the mattress that is damp is uncomfortable for the user, so the mattress should be regularly used. There is a custom of drying. In addition, in order to maintain a comfortable sleeping without discomfort, a sheet having water absorption properties has been developed which is laid on or under a mattress to absorb moisture from the mattress, for example, flexible and moisture-permeable. A sleep sheet comprising a first sheet and a flexible, moisture-permeable or moisture-impermeable second sheet on both sides and containing a water-absorbing polymer therebetween has been proposed (see Patent Document 1).
前記吸水性ポリマーとして、吸湿・放湿性に優れた架橋アクリル酸ナトリウム塩系繊維製不織布体（ベルオアシス：登録商標：鐘紡株式会社製）が市販されている。また、表裏二層の編地と該二層の編地を間隔をあけて連結する連結糸から構成される二重編地から成り、適度な嵩高性と反発性を有しながら通気性能を向上した充填材も提案（特許文献２参照）されていると共に、商品化されている（フュージョン：登録商標：旭化成工業株式会社製）。 As the water-absorbing polymer, a cross-linked sodium acrylate-based fiber nonwoven fabric (BEL OASIS: registered trademark: manufactured by Kanebo Co., Ltd.) excellent in moisture absorption and moisture release is commercially available. In addition, it consists of a double knitted fabric composed of two knitted fabrics on the front and back sides and a connecting yarn that connects the two knitted fabrics at an interval, improving air permeability while having moderate bulkiness and resilience. In addition to the proposed filler (see Patent Document 2), it has been commercialized (Fusion: registered trademark: manufactured by Asahi Kasei Kogyo Co., Ltd.).
前記従来の快眠シートは、両面を同程度の透湿性を有する材質の層で形成されているか、或いは、片面を不透湿性を有する材質の層で形成されているので、両面を透湿性層で形成した快眠シートにおいては、吸水性ポリマーが吸収した水分が両側の透湿性層から同じように放出することとなり、吸湿する側の透湿性層からも発散するので、吸水性ポリマーが保水状態になるに従って徐々に湿気が漂い不快感を感じるという問題点があった。また、片面を不透湿性層で形成した快眠シートにおいては、吸水性ポリマーが吸収した水分は発散しにくいので、中に溜まり易く湿気により不快感を感じるという問題点があった。 In the conventional sleep sheet, both sides are formed of a layer of material having the same degree of moisture permeability, or one side is formed of a layer of material having moisture permeability, so both sides are formed of a moisture permeable layer. In the formed sleep sheet, the moisture absorbed by the water-absorbing polymer is released from the moisture-permeable layers on both sides in the same way, and is also emitted from the moisture-permeable layer on the moisture-absorbing side. There was a problem that the moisture gradually drifted and the discomfort was felt. In addition, in the sleep sheet in which one side is formed with a moisture-impermeable layer, the moisture absorbed by the water-absorbing polymer is difficult to diverge, so that there is a problem in that it tends to accumulate inside and feels discomfort due to moisture.
そこで、本発明は、発汗作用による湿気を素早く吸湿すると同時に吸収した水分を吸湿する側とは反対側から発散させることができる吸湿性と通水性とに優れた敷パッドを得ることを技術的課題として、その具現化をはかるべく研究・実験を重ねた結果、吸湿・放湿性に優れた架橋アクリル酸ナトリウム塩系繊維により保水の働きをさせる不織布層を形成し、該不織布層を綿体を内包した透湿性を備えた表地層と適度な嵩高性と反発性を有しながら通気性能を向上した前記従来の充填材の層とにより挟むように積層すれば、発汗作用で発散した湿気が前記表地層から取り込まれて前記不織布層に吸収された水分が前記充填材層から蒸発して表地層から充填材層への湿気の流れが生じて利用者には不快感の無い快適な就寝が得られるという刮目すべき知見を得、前記技術的課題を達成したものである。 Therefore, the present invention provides a technical pad that is capable of quickly absorbing moisture due to the sweating action and at the same time diffusing the absorbed moisture from the side opposite to the side that absorbs moisture, which is excellent in moisture absorption and water permeability. As a result of repeated research and experimentation to realize its realization, a non-woven fabric layer that works to retain water is formed by a crosslinked sodium acrylate-based fiber having excellent moisture absorption and moisture release properties, and the non-woven fabric layer is encapsulated in cotton. If the layers are laminated so as to be sandwiched between the surface layer having moisture permeability and the layer of the conventional filler having improved air permeability while having moderate bulkiness and resilience, moisture diffused by sweating action can be obtained. Moisture taken in from the formation layer and absorbed by the nonwoven fabric layer evaporates from the filler layer, resulting in a flow of moisture from the surface layer to the filler layer, so that the user can have a comfortable sleep without discomfort. That Obtained a finding should, is obtained by achieving the technical problems.
前記技術的課題は、次の通りの本発明によって解決できる。 The technical problem can be solved by the present invention as follows.
