【産業上の利用分野】
本考案は消臭調湿畳に関するもので、更に詳しくは優れた消臭性と調湿性により畳自体の長期保存と安全で快適且衛生的居住環境を創出しえる消臭調湿畳に係るものである。
【０００２】
我が国は高温多湿な気候風土にあることから、かかる気候風土に適合した木造家屋と且畳や土壁、障子や襖等の内装材や建具等が古来より利用されてきており、現在においても地方や都市部郊外の戸建住居等には多用されている。
而しながら近年においては都市部への集中化が著しく進み、土地の有効利用のうえから都市部の住居は鉄筋コンクリートや鉄骨コンクリート構造による高層化住居が膨大数建設され、且この高層化住居に伴い建築金物類や建材等の軽量化が要請されたこととも相俟って、アルミサッシュやアルミ扉等の建築金物等に加えて天井床や壁材等にも新建材が多用されるに至ったため、該高層化住居内は極度に密閉性が高められる結果となっている。
【０００３】
更に郊外の戸建住居においても耐震性や耐火性若しくは防犯性に加え低コスト化が図れるプレハブ工法やプレカット工法の住居が積極的に採用されるに至り、且これら戸建住居にもアルミサッシュや新建材等が使用されたため、該戸建住居も極度に密閉性が高められた状況におかれている。
【０００４】
反面床材としての畳は、藁材を圧縮固化させてなる畳床と且この畳床を藺草で織成させた畳表で包被形成させてなるため、適度の緩衝性や柔軟性に加えて吸湿性を保持するため極めて使用感に優れる床材としては好適であるため、戸建住居にはもとより高層化住居にも多量に使用されている。
【０００５】
然るに高層化住居の如く鉄筋コンクリートや鉄骨コンクリートを躯体構造とする住居においては、コンクリート躯体の形成に際して多量の水分が使用されるために、形成後の躯体からの水分放出には極めて長期間を要するばかりか、該高層化住居内は著しく密閉性が高まっていることとも相俟って長期に亘って多湿状態に置かれ、而も高層化住居も躯体の形成とともに内装仕上げと且畳の敷込みもなされるためこれら多量の水分が該畳に吸水吸湿されることとなる。
【０００６】
更に戸建住居においても密閉性の高まりとともに建設される宅地の殆んどは十分な排水整備が施されてなく、これがため昼夜の温度差に伴い宅地地表面から多量の水蒸気が蒸散し床下材を介して畳に吸湿される結果となっている。
これがため折角吸湿性に優れる畳を使用しても湿気感やベト付感が畳表にまで拡散されて、特に高温多湿期には著しく不快となり且密閉性に伴う温暖化とも相俟って細菌や黴の繁殖が著しく増長されて、細菌臭や黴臭の発生ばかりか該細菌や黴の繁殖に伴い分泌される分泌物により畳や躯体の劣化や損傷も招来され、而もこれらを餌料としてダニ、シバンムシ等の衛生害虫が蝟集して吸血被害が惹起され、或いはこれらの死骸がアレルゲンとして小児喘息やアトピー性皮膚炎等の疾病を誘起させる原因ともなっている。
【０００７】
加えて畳表には生活における生活者の汗や体液、フケ、皮膚片等が落下付着し或いは食物残滓等も付着するため、これらが細菌や黴の恰好の餌料となるばかりか変性や分解が促進され悪臭の発生所謂生活臭気を発生するとともに、これら臭気が密閉性の高まりとも相俟って居住空間内に揮散滞留し、且内装材や畳或いは家具や調度品等に付着浸透して著しく不快な居住環境になされている。
而も密閉性の高まりにより、天井材や内装材等の新建材やその施工のための接着剤等から揮散される毒性の高い揮発性有機化合物、所謂シックハウス症候群原因物質が滞留し、これが吸湿性吸着性の優れる畳に多量に吸着されて著しく危険が増長される結果ともなっている。
【０００８】
考案者はかかる問題に鑑み研究を重ねた結果、人工ゼオライト粉体が多量のガス吸着性と湿気の吸湿性及び乾燥状態に伴う急速な放湿性所謂調湿性を保持すること、並びに揮発性有機化合物や臭気に対してもその保持する触媒作用と且強い塩基置換性とにより容易に分解消去及び分解消臭がなしえることを究明し、これにより所要の性能を保持する人工ゼオライト粉体をその吸着性や吸湿性を阻害させず且伸縮性を有する不織布に塗着させたうえ、畳表裏側に積層させ若しくは畳床に積層挟持させることにより問題を解決しえることを想到し本考案に至った。
【０００９】
【考案が解決しようとする課題】
本考案は多湿時や乾燥時にも略一定の湿度を保持して快適な使用感と細菌や黴の繁殖を抑制し、而も揮発性有機化合物や臭気を分解消去及び分解消臭して快適で安全且衛生的居住空間となしえる消臭調湿畳を提供することにある。
【００１０】
【課題を解決するための手段】
上述の課題を解決するために本考案が用いた技術的手段は、藁材からなる畳床が藺草を織成してなる畳表で包被形成される畳において、畳表や畳床に吸湿される湿気を積極的且効率的に吸湿させたうえ保湿し而も乾燥状態に伴って放湿させ、更には細菌や黴の繁殖により発生する臭気或いは居住空間で発生する生活臭気や揮発性有機化合物を、積極的且効率的に吸着させ且分解消臭並びに分解消去させるため、人工ゼオライト粉体にその平均粒径が５０μｍ以下の接触表面積率の極めて大きなものが用いられ、且大きな吸湿容量並びに吸着容量を保持させるうえから、その比表面積において少なくとも８０ｍ２／ｇ以上のものが使用される。
加えて細菌や黴の繁殖に伴う臭気や居住空間で発生する生活臭気や揮発性有機化合物等の有害ガスを、その保持する触媒作用と且強い塩基置換性とにより分解消臭並びに分解消去させるうえから、その塩基置換容量（ｍｅｑ／１００ｇ）において少なくとも２００ｍｇ以上の人工ゼオライト粉体が選択使用される。
【００１１】
そしてこの選択された人工ゼオライト粉体の優れた吸湿性や吸着性と分解消臭性や分解消去性を畳全体に亘って有効に発揮させるために、伸縮性を有する不織布を用い該人工ゼオライト粉体の吸湿性や吸着性が阻害されぬよう、且その絶対吸湿容量並びに絶対吸着容量を膨大容量に形成させるうえからその塗着重量が少なくとも５０ｇ／ｍ２以上で、而も湿気の吸湿や臭気或いは揮発性有機化合物の吸着にはこれらが混在する空気を人工ゼオライト粉体に接触通気させてやることが効果的であるため、該人工ゼオライト粉体の塗着に際しては空隙率が５乃至６０％に保持されるよう塗着させて消臭調湿布帛が形成される。
【００１２】
かくして形成された消臭調湿布帛を藁材からなる畳床を包被する藺草を織成してなる畳表の裏側に積層のうえ包被させてなる構造、若しくは藁材からなる畳床に該消臭調湿布帛を適宜数層に積層挟持させて畳床が形成されてなる構造、及び畳床が複数のインシュレーションボード若しくは合成樹脂発泡板材或いはこれらが交互に積層された積層間に、該消臭調湿布帛が挟持されてなる構造の消臭調湿畳に存する。
【００１３】
【作用】
本考案は以上の如き技術的手段を用いてなるため、次のような作用を有する。即ち人工ゼオライト粉体の優れた吸湿性並びに吸着性を畳全体に亘って発揮させるため、その平均粒径が５０μｍ以下の極めて接触表面積率が大きく且その比表面積が８０ｍ２／ｇ以上及び塩基置換容量（ｍｅｑ／１００ｇ）が２００ｍｇ以上の人工ゼオライト粉体が、伸縮性を保持する不織布にその吸湿性や吸着性が阻害されぬように、且塗着重量が５０ｇ／ｍ２以上で而も空隙率が５乃至６０％となるよう塗着されて消臭調湿布帛が形成されている。
【００１４】
そしてこの消臭調湿布帛を藁材からなる畳床に、藁材を織成させてなる畳表で包被形成される畳の畳表裏側に積層させたうえ包被させた構造、或いはこの藁材からなる畳床に該消臭調湿布帛を適宜数層に亘って積層挟持させた構造からなるため、床部に敷設使用されるに伴なってコンクリート躯体からの多量の吸湿や、戸建住居の床下地表面等からの多量の吸湿に際しても、積層され或いは積層挟持された消臭調湿布帛の吸湿接触表面積率が極めて大きく且吸湿容量も膨大量の人工ゼオライト粉体に、積極的且効率的に吸湿且保水されるため藁材自体への吸湿が著しく少なくなり而も乾燥に伴って順次吸湿されるため、湿度が略一定に保持されるとともに細菌や黴の繁殖が抑制され、且高温多湿時においても湿気感やムレ感の無い爽やかな使用感が保持される。
【００１５】
更に該消臭調湿布帛は、その空隙率が５乃至６０％に形成されてなるため十分に通気がなされるから、天然藁材の使用でも長期に亘って腐敗や劣化が防止されるばかりか、湿気を含む空気が人工ゼオライト粉体と容易に接触通気され吸湿される。
加えて該消臭調湿布帛に塗着されてなる人工ゼオライト粉体は、膨大量の吸着容量とともに触媒作用と且強い塩基置換性を保持するため、畳内部から発生する臭気は積極的且効率的に吸着されるとともに分解消臭され、而も居住空間で発生する生活臭気や揮発性有機化合物も畳表より積極的且効率的に吸着されるとともに分解消臭並びに分解消去されるばかりか、吸着飽和がなされぬため長期に亘って吸着性と分解消臭や分解消去機能が発揮される。
【００１６】
而も畳表に落下付着する汗や体液若しくは食物残滓等も、その裏側面には膨大な吸湿容量並びに吸着容量を保持し且分解消臭や分解消去機能を保持する消臭調湿布帛が積層されてなるため、細菌や黴の繁殖がなされず衛生害虫の蝟集も抑制される。加えて該消臭調湿布帛は伸縮性とともに柔軟なため、畳表裏側に積層させても包被が容易になしえ、而も藁材に適宜数層に積層挟持のうえ加圧成形させて畳床を形成する場合にも、その変形縮合に十分対処して積層挟持がなされる。
【００１７】
【実施例】
以下に本考案実施例を図とともに詳細に説明すれば、図１は人工ゼオライト粉体の拡大説明図、図２は消臭調湿布帛に用いる不織布の見取図、図３は消臭調湿布帛の拡大断面説明図であって、本考案に用いる人工ゼオライト粉体１は広大な居住空間の躯体から放湿される多量の湿気や居住空間内から発生する湿気や臭気或いは揮発性有機化合物等を吸湿並びに吸着せしめて、安全で快適且衛生的居住空間となす畳を提供するものであるから、これら湿気や臭気或いは揮発性有機化合物を積極的に吸湿吸着せしむるうえから、その吸湿接触表面積率が極めて大きなものが望まれるため、その平均粒径において５０μｍ以下望ましくは１０乃至３０μｍ程度のものが選択される。かかる場合に最低平均粒径が１０μｍに制約される所以は、該平均粒径が１０μｍ以下では塗着材の配合作業時に飛散が激しく作業性が著しく悪くなることによる。
【００１８】
更に人工ゼオライト粉体１は、その生成に際して通常水酸化ナトリウムからなるアルカリ剤を使用するためにナトリウムイオンを保持するものが一般的であるが、本考案の如く消臭を目的とする場合にはカルシウムや鉄イオンに置換させたものが望まれる。
そして該人工ゼオライト粉体１には多量の湿気を効率良く吸湿保水させ且乾燥状態に合せて放湿させる調湿性と、多量の臭気や揮発性有機化合物の効率良い吸着性を発揮させるうえからは吸湿及び吸着容量の大きなもの、所謂微細孔隙１Ａが多量に形成されてなるものが好適であることから、その比表面積においては少なくとも８０ｍ２／ｇ以上望ましくは１２０乃至１６０ｍ２／ｇ以上のものが使用される。
【００１９】
加えて人工ゼオライト粉体１が仮令吸着容量の大きなものでも使用経過とともに吸着量の増大により吸着飽和に至ると吸着性が喪失され、分解消臭や揮発性有機化合物の分解消去も不能となる。
而して人工ゼオライト粉体１は本来的に触媒作用を保持するものであり、且この触媒作用に強い塩基置換性が付加されることにより臭気に対する分解消臭と且揮発性有機化合物の分解消去がなされて吸着飽和が回避される。
これがため該人工ゼオライト粉体１にはその塩基置換容量（ｍｅｑ／１００ｇ）が少なくとも２００ｍｇ以上好ましくは２４０乃至２８０ｍｇの強い塩基置換性のものが選択される。
【００２０】
かくして吸湿性や吸着性に優れる人工ゼオライト粉体１の機能を畳全体に亘って発揮させるうえからは、畳を構成する畳表や畳床に簡便且自在に積層させ若しくは積層挟時させることが好都合であることから、該人工ゼオライト粉体１により消臭調湿布帛２を形成させる。
この消臭調湿布帛２は安価で簡便且自在に畳表や畳床に積層若しくは積層挟持させることが望まれるため、薄肉で伸縮性と柔軟住を保持する素材として不織布２Ａが好適なことから採用される。
【００２１】
この素材としての不織布２Ａは図２に示すように極めて多種多様な素材並びに製法によるものが上市されているが、本考案に用いる不織布２Ａとしては伸縮性や柔軟住と十分な空隙率を有し、且人工ゼオライト粉体１の塗着性をも具備するものであれば特段に制約はないが、使用素材としては廃棄住のうえからは綿や麻等の天然繊維素材が好適であるが、耐久使用性のうえからはポリアミド系やポリエステル系合成繊維素材が望ましい。
【００２２】
更に該不織布２Ａには伸縮性が要請されることから、望ましくは図３に示すようにフェルト製法やニードル製法による立体的に織成された不織布２Ａが好適であり、且該不織布２Ａに人工ゼオライト粉体１が塗着された場合にも、その空隙率が５乃至６０％程度に保持される必要上から原初の不織布２Ａの空隙率としては略３０乃至８０％程度のものが望まれる。
【００２３】
かくしてなる不織布２Ａには人工ゼオライト粉体１がその吸湿性や吸着性を阻害されぬよう且膨大な吸湿容量及び吸着容量を保持させるため、少なくとも５０ｇ／ｍ２以上望ましくは８０乃至１６０ｇ／ｍ２の塗着重量割合で塗着がなされる。
かかる場合に人工ゼオライト粉体１の吸湿性や吸着性を阻害させることなく塗着させる手段としては多様な手段が提案されるが、具体例を挙げればセルロース誘導体や澱粉、カゼイン等水溶性で且塗着固化時にも透湿性や透気性を保持する前処理材に予め人工ゼオライト粉体１を混合し、更に水溶性アクリル樹脂や合成ゴムラテックス、天然ゴムラテックス等からなる水溶性塗着材２Ｂを混合のうえ、不織布２Ａに少なくとも５０ｇ／ｍ２以上の塗着重量割合で塗着させる。そして所要の塗着重量割合で塗着させたるうえ加熱乾燥を施すことにより、人工ゼオライト粉体１に多量に吸水された水分が急速に蒸散することに伴い多量の蒸散孔を形成させることで消臭調湿布帛２が形成できる。
【００２４】
かかる如くして消臭調湿布帛２が形成されるものであるが、本考案は多湿時や乾燥時にも略一定の湿度を保持しで快適な使用感と細菌や黴の繁殖を抑制すること、及び揮発性有機化合物や臭気の分解消去並びに分解消臭をなし、安全で快適且衛生的居住空間となす畳の提供にある。
【００２５】
これがためには該消臭調湿布帛２を畳の内部に広範囲に配位させることであって、図４は畳表裏側に積層させ包被させた本考案３の断面説明図、かかる畳表３Ａの裏側に積層させる手段には特別なものはなく、畳表３Ａと略同形状に該消臭調湿布帛２を裁断のうえ、畳床３Ｂを畳表３Ａとともに包被させつつ側縁３Ｃを一体的に絡合させることにより積層使用がなされる。
【００２６】
畳表３Ａの裏側に消臭調湿布帛２を積層させる所以は、主として使用時における居住空間から発生する湿気や生活臭気並びに揮発性有機化合物、或いは畳表３Ａに落下付着する生活者の汗や体液或いは食物残滓等の変性、分解により招来される臭気の分解消臭や細菌及び黴の繁殖を抑制することにある。
【００２７】
他方畳はその使用時に建物躯体からの多量の吸湿や床下地表面からの多量の湿気が畳床３Ｂに吸湿されるため、該畳床３Ｂにも調湿機能や消臭機能を保持せしめる必要がある。
而しながら現状の畳床３Ｂは藁材３１Ｂを加圧成形させた藁床３２Ｂと、全体の軽量化を図るうえからインシュレーションボード３１Ｃ若しくは合成樹脂発泡板材３２Ｃを複数積層させたもの、或いはこれらを交互に積層させた建材畳床３１Ｄとが使用されている。
【００２８】
図５は本考案による藁床３０Ｂの断面説明図であって、一般的藁床３２Ｂは通常稲藁を縦横に略４乃至５層程度、厚さで略３５乃至４５ｃｍに積み重ねたうえ実質的に５乃至６ｃｍ程度の厚さまで加圧成形させて形成されるものである。
そこで該稲藁の積層される層間に消臭調湿布帛２を挟持させたうえ加圧成形させることにより、消臭調湿布帛２が伸縮性を保持するため稲藁の圧縮変形に対応して変形し積層挟持された藁床３０Ｂが形成されることとなる。
【００２９】
図６は本考案による建材畳床３０Ｃの断面説明図であって、従来の建材畳床３１Ｄはインシュレーションボード３１Ｃや合成樹脂発泡板３２Ｃが複数積層されてなるものであるから、該建材畳床３１Ｄのインシュレーションボード３１Ｃや合成樹脂発泡板材３２Ｃの積層間に、消臭調湿布帛２を挟持させるのみで形成がなされる。
【００３０】
かかる如くして形成された本考案藁床３０Ｂ或いは建材畳床３０Ｃを、畳表３Ａの裏側に消臭調湿布帛２を積層のうえ包被し、且その両側縁を適宜に縫合させることにより本考案消臭調湿畳３が形成されることとなる。
【００３１】
【考案の効果】
本考案は以上述べたように、藁材からなる畳床が藺草からなる畳表により包被形成されてなる畳の畳表の裏側に、若しくは藁材からなる畳床に適宜数層に或いは複数のインシュレーションボード若しくは合成樹脂発泡板材が積層され若しくはこれらが交互に積層された積層間に、伸縮性を有する不織布にその平均粒径が５０μｍ以下の接触表面積率が極めて大きく、且比表面積が少なくとも８０ｍ２／ｇ以上の吸湿容量や吸着容量が大きく、而も塩基置換容量（ｍｅｑ／１００ｇ）が２００ｍｇ以上の強い塩基置換性を有する人工ゼオライト粉体が、その吸湿性や吸着性を阻害されぬよう、且少なくとも５０ｇ／ｍ２以上の塗着重量割合で塗着され絶対吸湿容量及び絶対吸着容量も膨大量に形成された消臭調湿布帛が積層若しくは積層挟持されてなるため、敷設使用における躯体からの湿気や床下地表面からの湿気も畳床においては積層挟持された消臭調湿布帛の人工ゼオライト粉体に積極的効率的に且多量に吸湿されて保水され、而も乾燥状況に伴って放湿される調湿性が発揮されるため畳が略一定の湿度に保持され、細菌や黴の繁殖が著しく抑制されて衛生害虫の蝟集も無くなり、更には畳床の汚損や腐蝕も防止され而も畳表裏側に消臭調湿布帛が積層されることにより、高温多湿時にも蒸れ感やベト付感も無くなり快適な使用感に保持される。
【００３２】
加えて居住空間で発生する生活臭気や、内装材等から滲出揮散する揮発性有機化合物も畳表を通して消臭調湿布帛の人工ゼオライト粉体に積極的効率的に吸着されるとともに、その触媒作用と強い塩基置換性とにより短時に分解消臭及び分解消去がなされ、而も吸着飽和が無いため吸着性と分解消臭若しくは分解消去機能が長期に発揮される。
【００３３】
そして該消臭調湿布帛は伸縮性と柔軟住に優れるため畳表に積層のうえ畳床を包被し、或いは藁材内への積層挟持も容易になしえるとともに、空隙率が５乃至６０％に保持されてなるから、畳表が藺草や畳床が藁材等の天然素材による畳でも適度の通気がなされ長期に亘って素材の品質が維持され、更には畳表の近傍が常に一定の湿度に保持されるため畳表の乾燥に伴う変色も防止される等、極めて優れた特長を具備する消臭調湿畳である。

[Industrial applications]
The present invention relates to a deodorant controlled humidity tatami mat, and more particularly to a deodorized controlled tatami mat capable of creating a long-term preservation of the tatami itself and a safe, comfortable and hygienic living environment due to excellent deodorizing property and humidity controlling property. It is.
[0002]
Since Japan has a hot and humid climate, wooden houses and interior materials and fittings such as tatami mats, mud walls, shoji screens and sliding doors have been used since ancient times. It is frequently used for detached houses in urban and suburban areas.
However, in recent years, centralization in urban areas has progressed remarkably, and a large number of high-rise houses with reinforced concrete and steel-frame concrete structures have been constructed in urban areas after effective use of land. Along with the demand for weight reduction of building hardware and building materials, new building materials have been heavily used for ceiling floors and wall materials in addition to building hardware such as aluminum sashes and aluminum doors. As a result, the inside of the high-rise house is extremely improved in airtightness.
[0003]
In addition, prefabricated and pre-cut constructions have been actively adopted in suburban detached houses to reduce costs in addition to earthquake resistance, fire resistance or crime prevention. Due to the use of new building materials and the like, the detached houses are also in an extremely tightly closed state.
[0004]
On the other hand, a tatami mat as a floor material is formed by wrapping a tatami mat made by compressing and solidifying a straw material and a tatami mat made of tatami mats. Since it is suitable as a flooring material that is extremely excellent in usability because it retains moisture absorbability, it is used in large quantities not only in detached houses but also in high-rise houses.
[0005]
However, in houses with a skeleton structure made of reinforced concrete or steel-framed concrete, such as high-rise houses, a large amount of water is used to form the concrete frame, so it takes an extremely long time to release water from the frame after formation. Alternatively, the interior of the high rise dwelling is placed in a humid state for a long period of time in combination with the remarkable increase in hermeticity. Therefore, a large amount of water is absorbed and absorbed by the tatami mat.
[0006]
In addition, even in detached houses, most of the residential lands constructed with the increase in airtightness have not been adequately drained, so a large amount of water vapor evaporates from the residential land surface due to temperature differences between day and night, and As a result, the tatami is absorbed through the tatami.
Therefore, even if a tatami mat having excellent hygroscopicity is used, the feeling of moisture and stickiness is diffused to the surface of the tatami mat. Propagation of molds is remarkably increased, and not only the generation of bacterial odors and moldy odors, but also secretions secreted by the propagation of the bacteria and molds lead to deterioration and damage of tatami mats and frames. In addition, hygiene pests such as shibanmushi gather together to cause blood-sucking damage, or these dead bodies cause allergens to cause diseases such as childhood asthma and atopic dermatitis.
[0007]
In addition, sweat, body fluids, dandruff, skin fragments, etc. of consumers in daily life fall and adhere to the tatami mats, and food residues also adhere to them, so these not only become good food for bacteria and fungi, but also promote denaturation and decomposition. In addition to the generation of foul odors, so-called daily odors, these odors are volatilized and stagnate in the living space due to the increase in the airtightness, and adhere to and penetrate interior materials, tatami mats, furniture, furniture and the like, and are extremely unpleasant. It is made in a comfortable living environment.
Also, due to the increase in airtightness, highly toxic volatile organic compounds, so-called sick house syndrome causative substances, which are volatilized from new building materials such as ceiling materials and interior materials and adhesives for the construction thereof, stay there, and they absorb moisture. As a result, the danger is greatly increased because a large amount of tatami is adsorbed on the tatami mat having excellent adsorbability.
[0008]
The inventor has conducted research in view of such a problem, and as a result, the artificial zeolite powder has a large amount of gas adsorption, moisture absorption and rapid moisture release accompanying dry state, so-called humidity control, and volatile organic compounds. Of odor and odor can be easily decomposed / erased by the catalytic action and strong base substitution, and the artificial zeolite powder which maintains the required performance can be adsorbed. The present invention was conceived to solve the problem by applying a nonwoven fabric having elasticity without impairing the properties and hygroscopicity and then laminating it on the front and back sides of the tatami mat or laminating it on the tatami mat floor.
[0009]
[Problems to be solved by the invention]
The present invention maintains a substantially constant humidity even when humid or dry, and suppresses the sensation of use and the growth of bacteria and fungi.It also decomposes and eliminates volatile organic compounds and odors, and eliminates odors. It is an object of the present invention to provide a deodorant-controlled wet tatami mat that can be used as a safe and hygienic living space.
[0010]
[Means for Solving the Problems]
The technical means used by the present invention to solve the above-mentioned problem is that in a tatami mat in which a tatami floor made of straw material is wrapped with a tatami mat made of rush grass, moisture absorbed by the tatami mat and the tatami mat is absorbed. Actively and efficiently absorbs moisture and keeps it moisturizing and releases moisture as it dries. Furthermore, it actively removes odors generated by the propagation of bacteria and fungi, living odors generated in living spaces, and volatile organic compounds. An artificial zeolite powder having an average particle diameter of 50 μm or less and having a large contact surface area ratio is used for the purpose of efficiently and efficiently adsorbing, eliminating odor and decomposing and eliminating, and retains a large moisture absorption capacity and adsorption capacity. In order to achieve this, those having a specific surface area of at least 80 m 2 / g or more are used.
In addition, the odor associated with the propagation of bacteria and mold, the odor generated in living spaces and harmful gases such as volatile organic compounds can be eliminated and decomposed and eliminated by its catalytic activity and strong base substitution. Therefore, an artificial zeolite powder of at least 200 mg or more in its base substitution capacity (meq / 100 g) is selected and used.
[0011]
Then, in order to effectively exhibit the excellent hygroscopicity and adsorptivity, the odor-removing odor and the decomposability of the selected artificial zeolite powder over the entire tatami mat, the artificial zeolite powder is formed using a stretchable nonwoven fabric. In order not to hinder the hygroscopicity and adsorptivity of the body and to make its absolute moisture absorption capacity and absolute adsorption capacity enormous, the coating weight is at least 50 g / m 2 or more. Alternatively, it is effective to adsorb volatile organic compounds by contacting and aerating the air containing them with the artificial zeolite powder, so that when the artificial zeolite powder is applied, the porosity is 5 to 60%. To form a deodorant and controlled humidity cloth.
[0012]
The thus-formed deodorant-adjusted wet cloth is laminated on the backside of a tatami mat surface woven of rush to cover a tatami floor made of straw material, or the tatami floor made of straw material is deodorized. A structure in which a tatami floor is formed by appropriately sandwiching a plurality of layers of a humidity control cloth, and the deodorization is performed between a plurality of insulation boards or synthetic resin foam plates or a laminate in which these are alternately laminated. The present invention resides in a deodorant controlled humidity tatami mat having a structure in which a humidity control cloth is sandwiched.
[0013]
[Action]
Since the present invention uses the above technical means, it has the following operations. In other words, in order to exhibit the excellent hygroscopicity and adsorptivity of the artificial zeolite powder over the entire tatami mat, the contact surface area ratio with an average particle size of 50 μm or less is very large, the specific surface area is 80 m 2 / g or more, and the base substitution is performed. An artificial zeolite powder having a capacity (meq / 100 g) of 200 mg or more is coated with a weight of 50 g / m 2 or more so that the non-woven fabric having elasticity does not impair its hygroscopicity and adsorptivity. It is applied so that the ratio becomes 5 to 60% to form a deodorant and controlled humidity cloth.
[0014]
A structure in which this deodorant humidity-adjustable fabric is laminated on the front and back sides of a tatami mat wrapped with a tatami mat made of a straw material on a tatami floor made of a straw material and then wrapped, or this straw material Tatami floors made of the deodorant-type humidity-adjusting fabrics are laminated and sandwiched in several layers as appropriate, so that a large amount of moisture can be absorbed from the concrete frame as the floor is used and Even when a large amount of moisture is absorbed from the surface of the floor substrate, the laminated or sandwiched deodorant moisture-controlling cloth has an extremely large moisture-absorbing contact surface area ratio and an extremely large moisture-absorbing capacity. The moisture absorption into the straw material itself is remarkably reduced due to the moisture absorption and water retention, and the moisture is absorbed successively with the drying, so that the humidity is kept substantially constant, the growth of bacteria and mold is suppressed, and the temperature is high. Refreshing use without moisture or stuffiness even in humid conditions Feeling is held.
[0015]
Furthermore, since the odor-controlling moisture cloth is formed to have a porosity of 5 to 60% and is sufficiently ventilated, not only the use of natural straw but also the prevention of decay and deterioration for a long time can be prevented. In addition, the air containing moisture easily comes into contact with the artificial zeolite powder and is ventilated to absorb moisture.
In addition, the artificial zeolite powder coated on the deodorizing and conditioning fabric retains a catalytic action and strong base substitution with an enormous amount of adsorption capacity, so that the odor generated from inside the tatami is positive and efficient. The natural odor and volatile organic compounds generated in the living space are also positively and efficiently adsorbed from the tatami mat, and are not only eliminated but also decomposed and eliminated. Since the saturation is not performed, the adsorptivity, the odor for dissolving and the function of decomposing and erasing are exhibited over a long period of time.
[0016]
In addition, sweat, body fluids, food residues, and the like that fall and adhere to the tatami mat surface are laminated with a deodorizing and humidity-controlling cloth that retains an enormous moisture absorption capacity and an adsorption capacity and has a function of eliminating odors and decomposing and erasing. Therefore, bacteria and mold are not propagated, and the gathering of sanitary pests is suppressed. In addition, since the deodorant and humidity-controlling fabric is flexible as well as stretchable, it can be easily wrapped even when laminated on the front and back sides of the tatami mat. Even when a bed is formed, the laminate is sandwiched by sufficiently coping with the deformation condensation.
[0017]
【Example】
FIG. 1 is an enlarged explanatory view of an artificial zeolite powder, FIG. 2 is a sketch of a non-woven fabric used for a deodorizing and conditioning cloth, and FIG. FIG. 2 is an enlarged cross-sectional explanatory view, in which the artificial zeolite powder 1 used in the present invention absorbs a large amount of moisture released from the frame of a large living space, and moisture, odor or volatile organic compounds generated from the living space. In addition, since the tatami mats are provided to provide a safe, comfortable and sanitary living space by being adsorbed, these moisture, odor or volatile organic compounds are positively absorbed and adsorbed. Is very large, so that the average particle size is selected to be 50 μm or less, preferably about 10 to 30 μm. The reason why the minimum average particle size is limited to 10 μm in such a case is that when the average particle size is 10 μm or less, scattering is severe during compounding work of the coating material and workability is significantly deteriorated.
[0018]
Further, the artificial zeolite powder 1 generally retains sodium ions in order to use an alkali agent composed of sodium hydroxide in the production thereof. However, when the purpose is to deodorize as in the present invention, It is desired to substitute calcium and iron ions.
The artificial zeolite powder 1 is required to efficiently absorb and retain a large amount of moisture and to release moisture according to a dry state, and to exhibit efficient adsorption of a large amount of odors and volatile organic compounds. Since a material having a large moisture absorption and adsorption capacity, that is, a material having a large amount of so-called micropores 1A is suitable, the specific surface area is preferably at least 80 m 2 / g or more, more preferably 120 to 160 m 2 / g or more. used.
[0019]
In addition, even if the artificial zeolite powder 1 has a large temporary adsorption capacity, the adsorptivity is lost when the amount of adsorption increases with the lapse of use and the adsorption reaches saturation, so that the elimination odor and the decomposition and elimination of volatile organic compounds become impossible.
Thus, the artificial zeolite powder 1 inherently retains the catalytic action, and by adding a strong base substitution property to the catalytic action, the odor can be eliminated by odor and the volatile organic compound can be decomposed and eliminated. To avoid adsorption saturation.
Therefore, the artificial zeolite powder 1 is selected from those having a strong base substitution capacity of at least 200 mg or more, preferably 240 to 280 mg, in the base substitution capacity (meq / 100 g).
[0020]
Thus, in order to exhibit the function of the artificial zeolite powder 1 having excellent hygroscopicity and adsorptivity over the entire tatami mat, it is convenient to easily and freely laminate the tatami mat or the tatami mat floor or to sandwich the tatami mat. Therefore, the deodorant and controlled humidity cloth 2 is formed by the artificial zeolite powder 1.
Since it is desired that this deodorant-adjusted wet cloth 2 be inexpensive, easily and freely laminated or sandwiched on a tatami mat or a tatami floor, a nonwoven fabric 2A is adopted as a material that is thin and has elasticity and flexibility. Is done.
[0021]
As shown in FIG. 2, the nonwoven fabric 2A as this material is commercially available from a very wide variety of materials and manufacturing methods. However, the nonwoven fabric 2A used in the present invention has elasticity, flexibility and sufficient porosity. There is no particular limitation as long as it also has the coating property of the artificial zeolite powder 1, but natural fibers such as cotton and hemp are suitable for use from the viewpoint of disposal. From the viewpoint of durability, a polyamide-based or polyester-based synthetic fiber material is desirable.
[0022]
Further, since the non-woven fabric 2A is required to have elasticity, a three-dimensionally woven non-woven fabric 2A by a felt manufacturing method or a needle manufacturing method is preferably used as shown in FIG. Even when the powder 1 is applied, the porosity of the original nonwoven fabric 2A is desirably about 30 to 80% because the porosity must be maintained at about 5 to 60%.
[0023]
Thus it made since the nonwoven 2A to hold the且huge hygroscopic capacity and adsorption capacity as the artificial zeolite powder 1 unexpected inhibited its hygroscopicity and adsorptivity of at least 50 g / m 2 or more preferably 80 to 160 g / m 2 Is applied at a coating weight ratio of.
In such a case, various means have been proposed for applying the artificial zeolite powder 1 without impairing the hygroscopicity and adsorptivity of the artificial zeolite powder 1. Specific examples include water-soluble and cellulose derivatives, starch and casein. The artificial zeolite powder 1 is preliminarily mixed with a pretreatment material that retains moisture permeability and air permeability during coating and solidification, and then a water-soluble coating material 2B made of a water-soluble acrylic resin, synthetic rubber latex, natural rubber latex, or the like is added. After mixing, it is applied to the nonwoven fabric 2A at an application weight ratio of at least 50 g / m 2 or more. Then, by applying the coating at a required coating weight ratio and performing heating and drying, the artificial zeolite powder 1 is extinguished by forming a large amount of transpiration holes due to the rapid evaporation of a large amount of absorbed water. The odor control wet cloth 2 can be formed.
[0024]
Thus, the deodorant humidity control cloth 2 is formed. However, the present invention is to maintain a substantially constant humidity even when humid or dry, and to provide a comfortable feeling of use and suppress the growth of bacteria and fungi. Another object of the present invention is to provide a tatami mat that forms a safe, comfortable and sanitary living space by decomposing and eliminating volatile organic compounds and odors and eliminating odors.
[0025]
In order to achieve this, the deodorizing and adjusting wet cloth 2 is widely arranged inside the tatami mat. FIG. 4 is a cross-sectional explanatory view of the present invention 3 laminated and covered on the front and back sides of the tatami mat. There is no special means for laminating on the back side, and after cutting the deodorizing and adjusting wet cloth 2 into the substantially same shape as the tatami table 3A, the tatami floor 3B is covered with the tatami table 3A and the side edges 3C are integrally formed. Lamination is used by entanglement.
[0026]
The reason why the deodorant-adjustable moisture-absorbing fabric 2 is laminated on the back side of the tatami table 3A is mainly the dampness and living odor and volatile organic compounds generated from the living space at the time of use, or the sweat or body fluid of the resident who falls and adheres to the tatami table 3A. An object of the present invention is to suppress odors caused by denaturation and decomposition of food residues and the like, and to suppress the growth of bacteria and fungi.
[0027]
On the other hand, the tatami mat 3B is required to have a humidity control function and a deodorant function because the tatami floor 3B absorbs a large amount of moisture from the building frame and a large amount of moisture from the floor surface during use. is there.
However, the current tatami floor 3B is formed by laminating a plurality of straw boards 32B obtained by press-forming a straw material 31B and a plurality of insulation boards 31C or synthetic resin foam boards 32C in order to reduce the overall weight. And a building material tatami floor 31D in which are alternately stacked.
[0028]
FIG. 5 is a cross-sectional view of the straw bed 30B according to the present invention. A general straw bed 32B is generally made by stacking rice straws about 4 to 5 layers vertically and horizontally to a thickness of about 35 to 45 cm and substantially. It is formed by pressure molding to a thickness of about 5 to 6 cm.
Therefore, by holding the deodorizing and conditioning moisture-absorbing fabric 2 between the layers where the rice straw is laminated and press-molding, the deodorizing and conditioning moisture-absorbing fabric 2 retains elasticity, so that it corresponds to the compressive deformation of the rice straw. The straw bed 30B which is deformed and sandwiched is formed.
[0029]
FIG. 6 is an explanatory cross-sectional view of the building material tatami floor 30C according to the present invention. Since the conventional building material tatami floor 31D is formed by laminating a plurality of insulation boards 31C and synthetic resin foam plates 32C, the building material tatami floor is used. The formation is performed only by sandwiching the deodorant-adjusting wet cloth 2 between the lamination of the insulation board 31C and the synthetic resin foam plate 32C of 31D.
[0030]
The straw floor 30B or the building material tatami floor 30C thus formed according to the present invention is covered with the deodorant-adjusted moisture-absorbing fabric 2 laminated on the back side of the tatami mat table 3A, and the both side edges thereof are appropriately stitched together. The deodorizing and adjusting wet tatami mat 3 is formed.
[0031]
[Effect of the invention]
As described above, the present invention has a structure in which a tatami floor made of straw material is wrapped by a tatami mat made of rush, on the back side of a tatami mat, or on a tatami mat made of straw material in several layers or a plurality of insulations. The elastic non-woven fabric has an extremely large contact surface area ratio of 50 μm or less and a specific surface area of at least 80 m 2 between the lamination of laminated or alternately laminated foamed board or synthetic resin foam board material. / G or more, and the base substitution capacity (meq / 100 g) of the artificial zeolite powder having a strong base substitution property of 200 mg or more is not impaired in its moisture absorption property and adsorption property.且少not even have 50 g / m 2 or more the coating weight percentage in the coating deposited absolute moisture capacity and absolute adsorption capacity humidity deodorant tone formed enormous amount fabrics laminated or stacked sandwiching In the case of laying, the moisture from the skeleton and the moisture from the surface of the floor substrate are also actively and efficiently absorbed by the artificial zeolite powder of the deodorized and controlled humidity cloth laminated and held on the tatami floor. The tatami mat is kept at a substantially constant humidity because it retains water and the moisture is released according to the dry condition, the proliferation of bacteria and fungi is remarkably suppressed, and the gathering of sanitary pests is also eliminated, The tatami mat floor is prevented from being stained or corroded, and the deodorant humidity-adjusting fabric is laminated on the front and back sides of the tatami mat.
[0032]
In addition, living odors generated in the living space and volatile organic compounds leaching and volatilizing from interior materials are also positively and efficiently adsorbed through the tatami mat to the artificial zeolite powder of the deodorant and controlled humidity fabric, and its catalytic action Due to the strong base-substituting property, the elimination odor and decomposition elimination are performed in a short time, and since there is no adsorption saturation, the adsorption property and the elimination odor or decomposition elimination function are exhibited for a long time.
[0033]
And since the deodorant humidity control cloth is excellent in elasticity and soft dwelling, it can be laminated on a tatami surface and covered with a tatami floor, or can be easily sandwiched in a straw material, and the porosity is 5 to 60%. Therefore, even if the tatami mat is made of natural materials such as rugs and tatami mats and the tatami mats are made of natural material such as straw, proper ventilation is maintained and the quality of the material is maintained over a long period of time. It is a deodorant and humidity controlled tatami mat having extremely excellent features, such as being held, thereby preventing discoloration due to drying of the tatami mat.
