Description
【０００１】[0001]
本考案は、防水性に富み、湿度調節機能を有する畳に関するものである。 The present invention relates to a tatami mat that is highly waterproof and has a humidity control function.
【０００２】[0002]
従来、防水性あるいは透湿性を有する畳としては、畳表と畳床の間に防虫性、 防水性及び難燃性を有する薬剤を含浸させた緩衝材を配設した畳（実開昭５４− １０８５２５）、通気性を有する畳表と吸放湿性を有する畳床との間にシート状 の合成樹脂発泡材に多数の小孔を形成してなる緩衝材を配設した畳（実開昭５４ −１５７４１４）などが知られている。 しかし、上記従来の畳は防水性あるいは透湿性のいずれかに注目をし、その双 方の特性を同時に満たすものは知られていない。 Conventionally, as a tatami mat having waterproofness or moisture permeability, a tatami mat having a cushioning material impregnated with an insect-proof, waterproof, and flame-retardant agent is placed between the tatami mat and the tatami mat (Actual No. 54-108525), A tatami mat in which a cushioning material formed by forming a large number of small holes in a sheet-like synthetic resin foam material is placed between a tatami mat table having air permeability and a tatami mat floor having moisture absorption and desorption (Actual No. 54-157414). It has been known. However, the above-mentioned conventional tatami pays attention to either waterproofness or moisture permeability, and it is not known to satisfy both characteristics at the same time.
【０００３】[0003]
本考案は、上記従来の畳に鑑みなされたもので、室内の湿度が高くなったとき は畳がある程度吸収し、室内の空気が乾燥したときは畳内の湿気を放出して室内 の湿度調節機能を有する透湿性と水分の透過を遮断する防水性とを合わせ持つ畳 を提供するものである。 The present invention has been made in view of the above-mentioned conventional tatami mat. When the indoor humidity becomes high, the tatami mat absorbs the moisture to some extent, and when the indoor air dries, the humidity in the tatami mat is released to control the indoor humidity. It provides a tatami mat that has both moisture permeability that has a function and waterproof properties that block the permeation of moisture.
【０００４】[0004]
本考案によれば、畳表と畳床の間に透湿防水性シートを介在させた畳が提供さ れ、又透湿度が２０００ｇ／ｍ2・ｄａｙ（ＪＩＳ−Ｚ０２０８に準ずる）以上で ある透湿防水性シートを畳表と畳床の間に介在させた畳が提供される。 すなわち、充填剤を添加した合成樹脂シートを延伸して微細孔を生じさせるこ とにより透湿性と防水性を合わせ持つシートを得、該シートを畳表と畳床の間に 介在させることにより衛生的で、湿度調節機能を有する畳が得られることを見出 し本考案に到達したものである。According to the present invention, a tatami mat having a moisture-permeable and waterproof sheet interposed between the tatami mat and the tatami floor is provided, and the moisture-permeable and waterproof property is 2000 g / m 2 · day (according to JIS-Z0208) or more. A tatami mat is provided with a sheet interposed between the tatami mat and the tatami floor. That is, a synthetic resin sheet containing a filler is stretched to form micropores to obtain a sheet having both moisture permeability and waterproofness, and the sheet is interposed between the tatami mat and the tatami floor to achieve hygiene, The inventors arrived at the present invention by discovering that a tatami mat having a humidity control function can be obtained.
【０００５】 以下本考案の一実施例を示す図面に基づいて説明する。 図１は本考案の透湿防水性畳の断面図であり、い草よりなる畳表（１）とわら 、インシュレーションボード、発泡ポリスチレンなどからなる畳床（２）の間に 透湿防水性シート（３）を介在させたものである。前記透湿防水性シートとして は、炭酸カルシウム、タルクなどの充填剤を添加したポリエチレン、ポリプリピ レンなどの合成樹脂シートを一軸または二軸方向に延伸して微細孔を生じさせた ものが用いられる。該微細孔を有する合成樹脂シートの透湿度は２０００ｇ／ｍ 2 ・ ｄａｙ以上、より好ましくは４０００ｇ／ｍ2・ｄａｙ以上でなければ室内の 湿度調節機能を期待することができない。An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a moisture-permeable and waterproof tatami mat of the present invention. A moisture-permeable waterproof sheet ( 3) is interposed. As the moisture-permeable waterproof sheet, a sheet obtained by uniaxially or biaxially stretching a synthetic resin sheet such as polyethylene or polypropylene to which a filler such as calcium carbonate or talc is added to form fine pores is used. The water vapor permeability of the synthetic resin sheet having the fine pores is 2000 g / m. 2 ・ Day or more, more preferably 4000 g / m2・ If it is not more than day, you cannot expect the indoor humidity control function.
【０００６】 上記透湿防水性シートを得るためには平均粒径が１０μｍ以下、好ましくは０ ．５〜５．０μｍの炭酸カルシウム、タルクなどの充填剤を合成樹脂１００重量 部に対して５０〜５００重量部、好ましくは１００〜４００重量部添加したシー トを一軸または二軸方向に１．０５〜７．５倍延伸する。７．５倍を越えて延伸 すると孔が大きくなって防水性が低下し好ましくない。上記透湿防水性シートの 厚みは１５〜５０μｍが好ましい。In order to obtain the above-mentioned moisture-permeable waterproof sheet, the average particle size is 10 μm or less, preferably 0. A sheet containing 5 to 5.0 μm of a filler such as calcium carbonate and talc added in an amount of 50 to 500 parts by weight, preferably 100 to 400 parts by weight, relative to 100 parts by weight of the synthetic resin is uniaxially or biaxially 1.05. ~ Stretch 7.5 times. If it is stretched over 7.5 times, the pores become large and the waterproof property deteriorates, which is not preferable. The thickness of the moisture-permeable waterproof sheet is preferably 15 to 50 μm.
【０００７】 上記透湿防水性シートの防水性は、上記の範囲の延伸条件であれば合成樹脂シ ート本来の防水性を損なうことがない。 上記透湿防水性シートの他の特性として、通気度が２００ｓｅｃ／１００ｃｃ （ＪＩＳ−Ｐ８１１７に準ずる）以上好ましくは３００ｓｅｃ／１００ｃｃ以上 、耐水圧が５００ｍｍＨ2 Ｏ（ＪＩＳ−Ｌ１０９２に準ずる）以上好ましくは１ ０００ｍｍＨ2 Ｏ以上であることが好ましい。The waterproofness of the moisture-permeable waterproof sheet does not impair the original waterproofness of the synthetic resin sheet under the stretching conditions in the above range. As other characteristics of the moisture-permeable waterproof sheet, the air permeability is 200 sec / 100 cc (according to JIS-P8117) or more, preferably 300 sec / 100 cc or more, and the water pressure resistance is 500 mmH 2 O (according to JIS-L1092) or more, preferably 1 It is preferably 000 mmH 2 O or more.
【０００８】 上記透湿防水性シートと不織布を積層したものを畳表と畳床の間に介在させた 場合はクッション性に優れた畳が得られ居住性が向上する。また、不織布の他に 紙、布などを積層して用いることもできる。この場合、不織布、布、紙などは畳 床側に配設するのが好ましい。 また、透湿防水性シートと不織布を積層したもので畳床を包んだ場合は、いず れの方向から畳に水分がかかっても畳床が濡れることがなく衛生的で好ましい。When the laminate of the moisture-permeable and waterproof sheet and the nonwoven fabric is interposed between the tatami mat and the tatami mat, a tatami mat excellent in cushioning property is obtained and the habitability is improved. Further, in addition to the non-woven fabric, paper, cloth, etc. may be laminated and used. In this case, it is preferable to dispose non-woven fabric, cloth, paper, etc. on the tatami floor side. When the tatami floor is wrapped with a laminate of a moisture-permeable waterproof sheet and a non-woven fabric, the tatami floor will not get wet even if moisture is applied to the tatami from any direction, which is hygienic and preferable.
【０００９】[0009]
以上の述べたごとく、本考案の透湿防水性畳は、畳表と畳床の間に微細孔を有 する合成樹脂シートを介在させているので、室内の湿度が高いときは畳床が前記 合成樹脂シートを通して湿気を吸収し室内が乾燥したときは湿気を放出するとい う湿度の調節作用をするものであり、畳表側から水がこぼれた場合には、前記合 成樹脂シートで水が遮断されるため畳床は濡れることがなく衛生的である。また 、前記合成樹脂シートで畳床を包んだ場合には畳床は畳の上下からの水にも濡れ ることがなく非常に衛生的である。 As described above, since the moisture-permeable waterproof tatami mat of the present invention has the synthetic resin sheet having fine holes between the tatami mat and the tatami mat, when the indoor humidity is high, the tatami mat becomes the synthetic resin sheet. It absorbs moisture through the room and releases it when the room is dry.It has a function of controlling the humidity.When water spills from the tatami mat side, the synthetic resin sheet blocks the water. The tatami floor is not wet and is hygienic. Further, when the tatami floor is wrapped with the synthetic resin sheet, the tatami floor does not get wet with water from above and below the tatami mat and is very hygienic.
