ところで、ヒトの覚醒度は脳波のα波と相関があり、眠気を感じる状態すなわち覚醒度が低い状態では、α波パワースペクトル積分値の閉眼／開眼比が低く、全般的活性を感じる状態すなわち覚醒度が高い状態では、α波パワースペクトル積分値の閉眼／開眼比が高い。なお、α波パワースペクトル積分値の閉眼／開眼比については、非特許文献１に詳細が記載されており、本明細書においてもα波パワースペクトル積分値の閉眼／開眼比の定義は、非特許文献１に定義されるものとする。
By the way, the degree of arousal in humans correlates with the α wave of the brain wave, and in the state of feeling drowsy, that is, the state of low arousal, the closed / open ratio of the α wave power spectrum integrated value is low, and the state of feeling general activity, that is, arousal. In a high degree state, the closed / open ratio of the alpha wave power spectrum integrated value is high. The details of the closed-eye / open-eye ratio of the α-wave power spectrum integrated value are described in Non-Patent Document 1, and the definition of the closed-eye / open-eye ratio of the α-wave power spectrum integrated value is also non-patented in the present specification. It shall be defined in Document 1.
一方、ヒトのくつろぎ度は心拍数と相関があり、リラックスした状態すなわちくつろぎ度が高い状態では心拍数が低く、緊張した状態、すわなち、くつろぎ度が低い状態では心拍数が高くなる。なお、心拍数の解析については、非特許文献１に詳細が記載されており、本明細書においても心拍数の定義は、非特許文献１に定義されるものとする。
On the other hand, the degree of relaxation in humans correlates with the heart rate, and the heart rate is low in a relaxed state, that is, in a state of high relaxation, and high in a tense state, that is, in a state of low relaxation.

本実施形態の濾材は、α波パワースペクトル積分値の閉眼／開眼比を高め、かつ、心拍数を下げる影響を与える有効成分を含有する不織布を備えることで、α波パワースペクトル積分値の閉眼／開眼比を高め、かつ、心拍数を下げる影響を与える有効成分を放出する機能を有している。 Hereinafter, embodiments of the present invention will be described in detail.
The filter medium of the present embodiment is provided with a non-woven fabric containing an active ingredient having an effect of increasing the eye closing / opening ratio of the α wave power spectrum integrated value and lowering the heart rate, so that the eye closing / eye opening of the α wave power spectrum integrated value is provided. It has the function of releasing an active ingredient that has the effect of increasing the eye opening ratio and lowering the heart rate.
本実施形態の濾材は、α波パワースペクトル積分値の閉眼／開眼比を高め、かつ、心拍数を下げる影響を与える有効成分を含有する不織布を備えることで、α波パワースペクトル積分値の閉眼／開眼比を高め、かつ、心拍数を下げる影響を与える有効成分を放出する機能を有している。 Hereinafter, embodiments of the present invention will be described in detail.
The filter medium of the present embodiment is provided with a non-woven fabric containing an active ingredient having an effect of increasing the eye closing / opening ratio of the α wave power spectrum integrated value and lowering the heart rate, so that the eye closing / eye opening of the α wave power spectrum integrated value is provided. It has the function of releasing an active ingredient that has the effect of increasing the eye opening ratio and lowering the heart rate.
有効成分を放出させる手段としては、有効成分を不織布に保持させてもよいし、有効成分を担持したセラミックスを不織布に保持させてもよい。
As a means for releasing the active ingredient, the active ingredient may be held on the non-woven fabric, or the ceramics carrying the active ingredient may be held on the non-woven fabric.
有効成分をセラミックスに担持させる方法は、特に限定されないが、例えばセラミックスと有効成分の共晶体を作成する方法や、多孔質セラミックスに有効成分の溶液を吸収させたのちに乾燥する方法がある。
The method of supporting the active ingredient on the ceramics is not particularly limited, but there are, for example, a method of forming a co-crystal of the ceramics and the active ingredient, and a method of allowing the porous ceramics to absorb the solution of the active ingredient and then drying.
α波パワースペクトル積分値の閉眼／開眼比を高め、かつ、心拍数を下げる影響を与える有効成分の例としては、リラックス効果の得られるフィトンチッドなどの森林浴成分、柑橘類の芳香成分、覚醒効果の得られるカフェイン類などを挙げることができる。これら成分は１種類のみ用いても、複数を用いてもよい。また、芳香成分については、ヒトが芳香を感じない臭気閾値以下の濃度での放出でもよい。
Examples of active ingredients that increase the closed / open eye ratio of the alpha wave power spectrum integrated value and lower the heart rate include forest bathing ingredients such as phytoncide, which have a relaxing effect, citrus aroma components, and arousal effects. Caffeine that is used can be mentioned. Only one kind of these components may be used, or a plurality of these components may be used. Further, the aroma component may be released at a concentration equal to or lower than the odor threshold at which humans do not feel the aroma.
本発明の濾材では、セラミックスに担持された有効成分とセラミックスとの質量比は、１／１０～１０／１とすることが好ましく、１／３～３／１とすることがより好ましい。有効成分とセラミックスとの質量比が１／１０よりも小さければ、有効成分に対してセラミックスが必要以上に含有され、経済的な無駄が生じる。あるいは、有効成分が少なすぎ効果が生じ難い場合がある。一方、有効成分とセラミックスとの質量比が１０／１よりも大きければ、セラミックスでの保持ができず、有効成分の安定性が低下する場合がある。
In the filter medium of the present invention, the mass ratio of the active ingredient supported on the ceramics to the ceramics is preferably 1/10 to 10/1, more preferably 1/3 to 3/1. If the mass ratio of the active ingredient to the ceramics is smaller than 1/10, the ceramics are contained more than necessary with respect to the active ingredient, resulting in economic waste. Alternatively, the active ingredient may be too small to produce the effect. On the other hand, if the mass ratio of the active ingredient to the ceramics is larger than 10/1, the ceramics cannot hold the active ingredient, and the stability of the active ingredient may decrease.
セラミックスは、珪酸系であるコロイダルシリカ、ケイ酸カルシウム、エチルシリケート、ケイ酸ナトリウム、ケイ酸カリウム、ケイ酸リチウム、アルミナ系であるアルミン酸カルシウム、β－アルミナ、ベーマイト、アルミナゾル、リン酸系であるリン酸カルシウム、リン酸アルミニウム及びリン酸マグネシウムからなる無機素材から選択されることが好ましい。
Ceramics are silicic acid-based colloidal silica, calcium silicate, ethyl silicate, sodium silicate, potassium silicate, lithium silicate, alumina-based calcium aluminate, β-alumina, boehmite, alumina sol, and phosphoric acid-based. It is preferably selected from an inorganic material consisting of calcium phosphate, aluminum phosphate and magnesium phosphate.
セラミックスは、微粒子であることが好ましく、その表面ないしは内部に有効成分が担持されている。セラミックスが微粒子である場合、その平均粒子径は、５０μｍ以下、さらに２０μｍ以下に制御することが好ましい。下限については、特に限定はないが、１μｍ前後、さらにはサブミクロン（０．１μｍ）のオーダーとすることも可能である。粒子径が小さい、すなわち比表面積が大きいと、セラミックス内部の担持されている有効成分がすみやかに放出されるために有利である。
Ceramics are preferably fine particles, and the active ingredient is supported on the surface or inside thereof. When the ceramics are fine particles, the average particle size thereof is preferably controlled to 50 μm or less, more preferably 20 μm or less. The lower limit is not particularly limited, but may be on the order of about 1 μm or even submicron (0.1 μm). A small particle size, that is, a large specific surface area, is advantageous because the active ingredient carried inside the ceramics is quickly released.
有効成分を担持したセラミックスを不織布に含有させる方法は、特に限定されないが、アクリル樹脂等のバインダーを溶解した水にセラミックスを分散した液に不織布を浸し、絞って乾燥させる方法などが挙げられる。この際、セラミックスと同時に、抗菌剤、難燃剤、着色のための顔料等も同時に含有させることも可能である。
The method of containing the ceramics carrying the active ingredient in the non-woven fabric is not particularly limited, and examples thereof include a method of immersing the non-woven fabric in a liquid in which the ceramics are dispersed in water in which a binder such as an acrylic resin is dissolved, and squeezing and drying the non-woven fabric. At this time, it is also possible to simultaneously contain an antibacterial agent, a flame retardant, a pigment for coloring and the like at the same time as the ceramics.
また、セラミックスを不織布に含有させた構造として、２枚の不織布でセラミックスを保持する構造とすることも可能である。この場合、２枚の不織布にセラミックスを保持する方法として、熱圧着により不織布を溶融させて接着する方法、バインダー成分を不織布に塗布して貼り合わせる方法、セラミックスに粉末状のバインダーを混合して２枚の不織布に挟み圧着する方法などが挙げられる。
It is also possible to have a structure in which the ceramics are contained in the non-woven fabric, and the ceramics are held by two non-woven fabrics. In this case, as a method of holding the ceramics on the two non-woven fabrics, a method of melting and adhering the non-woven fabric by thermocompression bonding, a method of applying a binder component to the non-woven fabric and bonding the ceramics, and a method of mixing the ceramics with a powdery binder 2 Examples thereof include a method of sandwiching and crimping between sheets of non-woven fabric.
バンダーと有効成分を担持したセラミックスとの質量比率は、１／１よりもバインダー量が少ないことが好ましい。バインダー量が多いと、濾材においてセラミックスの露出部分が減り、有効成分の放出量が減少するため、得られる効果が低くなるからである。また、バンダーと有効成分を担持したセラミックスとの質量比率は、１／１０よりもバインダー量が多いことが好ましい。これよりもバインダー量が少ないと、実質的に濾材にセラミックスを固着することが困難だからである。
The mass ratio of the bander to the ceramics carrying the active ingredient is preferably smaller than 1/1. This is because when the amount of the binder is large, the exposed portion of the ceramics in the filter medium is reduced, and the amount of the active ingredient released is reduced, so that the obtained effect is lowered. Further, the mass ratio of the bander to the ceramics carrying the active ingredient is preferably more than 1/10 in the amount of the binder. This is because if the amount of the binder is smaller than this, it is practically difficult to fix the ceramics to the filter medium.
本発明の濾材において、不織布に含有される有効成分を担持したセラミックスの量（不織布１ｍ２当たりの質量）は、１～１０ｇ／ｍ２であることが好ましい。１ｇ／ｍ２よりも少なくなると効果が得られにくくなり、１０ｇ／ｍ２よりも多くなると通気抵抗の上昇など、濾材やフィルターとしての実用化が困難になる。
In the filter medium of the present invention, the amount of ceramics carrying the active ingredient contained in the nonwoven fabric (mass per 1 m 2 of the nonwoven fabric) is preferably 1 to 10 g / m 2 . If it is less than 1 g / m 2 , it becomes difficult to obtain the effect, and if it is more than 10 g / m 2 , it becomes difficult to put it into practical use as a filter medium or a filter, such as an increase in ventilation resistance.
本発明のエアフィルターは、本発明の濾材を用いるものであり、例えば、プリーツ加工や、枠などへの取り付け加工が施されていてもよい。また、本発明のエアフィルターは、本発明の濾材に他の材料を組み合わせて形成されてもよい。
The air filter of the present invention uses the filter medium of the present invention, and may be pleated or attached to a frame or the like, for example. Further, the air filter of the present invention may be formed by combining the filter medium of the present invention with another material.
