Abstract
Description
本発明は、吸収材、ならびにそれを用いた吸収性物品およびペット排泄用シートに関する。 The present invention relates to an absorbent material, and an absorbent article and a pet excretion sheet using the absorbent material.
トイレトレーに取り付けて用いられるペット排泄用シートなどのペット排泄用吸収性物品には、排泄物に起因する悪臭を消臭するために消臭剤が含まれている場合が多い。例えば、特許文献１には消臭剤として、木材から抽出された精油と、炭素数４～２４のアルコール類及びそのモノアルキルエーテルからなる群から選択される１種以上のアルコール類を使用することが提案されている。 Absorbent articles for pet excretion, such as pet excretion sheets used by attaching to toilet trays, often contain a deodorant to deodorize the malodor caused by excrement. For example, in Patent Document 1, as a deodorant, one or more alcohols selected from the group consisting of essential oils extracted from wood, alcohols having 4 to 24 carbon atoms and their monoalkyl ethers are used. Has been proposed.
また、特許文献２には、透液性の表面シートと、不透液性の裏面シートと、表面シートと裏面シートとの間に介在する吸収体とを備えているペット排泄用シートであって、木材から抽出された精油をテクトケイ酸塩に担持させた芳香性粉体を含むペット排泄用シートが提案されている。 Further, Patent Document 2 is a pet excretion sheet provided with a liquid-permeable front surface sheet, an impermeable back surface sheet, and an absorber interposed between the front surface sheet and the back surface sheet. , A pet excretion sheet containing an aromatic powder in which an essential oil extracted from wood is carried on a tect silicate has been proposed.

Since this material is a solid substance and is non-volatile, the absorbent material containing the material can exhibit the function (for example, deodorizing effect) of the material for a long period of time.
（本発明の一実施形態に至った経緯）
特許文献１および２等で提案されている精油は、天然物由来であることから利用者に安心感を与えやすく、これを消臭剤として用いた吸収材を含む吸収性物品の付加価値を高めることができる。一方で、精油は揮発しやすいという性質を有し、例えば、製品を保管している間に徐々に揮発することがある。あるいは、ペット排泄用シートのように、トイレトレーに広げて取り付けてから、そのままの状態で比較的長時間（例えば、１日ないし２日）放置される場合には、精油の揮発が進行して、取り替え間際には精油による消臭機能が十分に発揮されないこともある。また、精油は所定量の原料から採取できる量が僅かであることから比較的高価であり、これを大量に使用するとコスト上昇を招くことがある。
(Background to the embodiment of the present invention)
Since the essential oils proposed in Patent Documents 1 and 2 are derived from natural products, it is easy to give users a sense of security, and the added value of absorbent articles including absorbent materials using this as a deodorant is enhanced. be able to. On the other hand, essential oils have the property of being easily volatilized, and may gradually volatilize, for example, during storage of the product. Alternatively, like a pet excretion sheet, if the essential oil is left unfolded on a toilet tray and then left as it is for a relatively long time (for example, 1 to 2 days), the essential oil will volatilize. In some cases, the deodorizing function of the essential oil may not be fully exerted just before replacement. In addition, essential oils are relatively expensive because the amount that can be collected from a predetermined amount of raw materials is small, and if they are used in large quantities, the cost may increase.
本発明者らは、精油以外の材料であって、精油と同様の消臭機能を吸収材に付与できる材料の有無を検討した。その結果、樹木の木質部および／または葉から精油等を除去した材料が、排泄物の臭い（例えば、アンモニア臭、硫化水素臭、およびメチルメルカプタン臭から選択される少なくとも１つの臭い、特にアンモニア臭）に対して優れた消臭機能を発揮し、また、不揮発性であって、吸収性物品に比較的長時間にわたって消臭効果を付与することを見出し、本実施形態に至った。 The present inventors examined the presence or absence of a material other than the essential oil that can impart the same deodorizing function as the essential oil to the absorbent material. As a result, the material from which essential oils and the like have been removed from the woody part and / or leaves of the tree has an excrement odor (for example, at least one odor selected from an ammonia odor, a hydrogen sulfide odor, and a methyl mercaptan odor, particularly an ammonia odor). It has been found that it exhibits an excellent deodorizing function, is non-volatile, and imparts a deodorizing effect to an absorbent article for a relatively long period of time, and has reached the present embodiment.
（精油および水分の少なくとも一部が除去された材料）
本発明の一実施形態は、樹木の木質部および／または葉から、精油および水分の少なくとも一部が除去された材料を含有する、吸収材である。まず、この材料について説明する。
本実施形態で用いる材料は、樹木の木質部および／または葉から、精油および水分の少なくとも一部を除去することにより得られるものであり、精油および水分の少なくとも一部を取り出した後の残渣（または残留物）とも言えるものである。したがって、当該材料においては、それに含まれる液体（一般には、精油および水分）の量が、生木に含まれる液体の量よりも少なく、生木と比較してより乾燥した状態のものである。
(Material from which at least part of the essential oil and water has been removed)
One embodiment of the invention is an absorbent containing a material from which at least a portion of essential oil and water has been removed from the xylem and / or leaves of a tree. First, this material will be described.
The material used in this embodiment is obtained by removing at least a part of the essential oil and water from the xylem and / or leaves of the tree, and is a residue (or after removing at least a part of the essential oil and water). It can also be said to be a residue). Therefore, in the material, the amount of liquid (generally, essential oil and water) contained therein is smaller than the amount of liquid contained in the raw wood, and the material is in a drier state as compared with the raw wood.
当該材料は、樹木の木質部および／または葉から精油および水分の少なくとも一部が除去されたものである。当該材料はいずれの方法で得られたものであってよく、例えば、伐採された樹木の木質部および／または葉を減圧下で、精油分（および水分）を蒸留により、除去（すなわち、抽出する）方法で得られたものであってよい。減圧下での蒸留はマイクロ波を照射しながら実施してよい。マイクロ波照射を行いながら減圧下で精油分（および水分）を蒸留、抽出する方法（以下、「減圧水蒸気蒸留法」という）は、マイクロ波が水分子を直接加熱する性質を利用して、素材中に元から含まれている水分のみで精油の抽出を行う方法である。減圧水蒸気蒸留法によって得られた当該材料は、粉砕されやすく、特に機械的な加工で粉砕されやすいため、粉状物として用いるのに適している。減圧水蒸気蒸留法の詳細は、例えば、特許文献３および４に記載されている。 The material is the xylem and / or leaves of the tree from which at least a portion of the essential oil and water has been removed. The material may be obtained by any method, for example, the xylem and / or leaves of the felled tree are removed (ie, extracted) by distillation under reduced pressure. It may be obtained by the method. Distillation under reduced pressure may be carried out while irradiating with microwaves. The method of distilling and extracting essential oils (and water) under reduced pressure while irradiating with microwaves (hereinafter referred to as "reduced steam distillation method") utilizes the property that microwaves directly heat water molecules to make a material. This is a method of extracting essential oils using only the water originally contained in the oil. The material obtained by the vacuum steam distillation method is easily pulverized, and particularly easily pulverized by mechanical processing, and is therefore suitable for use as a powder. Details of the vacuum steam distillation method are described in, for example, Patent Documents 3 and 4.
あるいは、樹木の木質部および／または葉から精油のみを少なくとも一部除去し、別の工程にて水分を除去する方法、または樹木の木質部および／または葉から精油および水分の少なくとも一部を除去し、別の工程にてさらに水分の少なくとも一部を除去する方法によって、本実施形態で使用する材料を得てもよい。樹木の木質部および／または葉に含まれる水分の一部は、これらを粉状物に加工する前に又は加工している間に、乾燥処理を実施することにより、除去することもできる。 Alternatively, a method of removing at least a portion of the essential oil and / or leaves from the xylem and / or leaves of the tree and removing water in another step, or removing at least a portion of the essential oil and water from the xylem and / or leaves of the tree. The material used in this embodiment may be obtained by a method of further removing at least a part of water in another step. Some of the moisture contained in the xylem and / or leaves of the tree can also be removed by performing a drying process before or during the processing of these into powder.
本実施形態で用いる材料は、樹木の木質部、即ち、枝、幹および根のいずれか１つまたは複数に由来するものであってよく、あるいは樹木の葉に由来するものであってよく、あるいは樹木の木質部と葉の双方に由来するものであってよい。その意味で、「および／または」という用語が使用されている。樹木の木質部と葉の双方に由来する当該材料は、例えば、製材工程において樹木の幹から落とされた枝葉（枝に葉がついた状態のもの）を減圧水蒸気蒸留法による精油の抽出に付して得られるものであってよい。 The material used in this embodiment may be derived from the xylem of the tree, i.e., one or more of the branches, trunks and roots, or may be derived from the leaves of the tree, or the tree. It may be derived from both the xylem and the leaves. In that sense, the term "and / or" is used. The material derived from both the xylem and the leaves of the tree is, for example, the branches and leaves (with leaves attached to the branches) dropped from the trunk of the tree in the sawing process, and the essential oil is extracted by the vacuum steam distillation method. It may be obtained.
本実施形態で用いる材料は、少なくとも樹木の葉に由来するものであることがより好ましい。「少なくとも樹木の葉に由来する」とは、当該材料が樹木の葉に由来する成分または部分を含むことをいい、「少なくとも樹木の葉に由来する」材料は、樹木の木質部に由来する成分または部分をさらに含んでよい。当該材料が少なくとも樹木の葉に由来するものであることは、例えば光学顕微鏡で当該材料を観察したときに、葉緑体に由来する緑色または青色の部分が当該材料に含まれていることで確認することができる。当該材料が少なくとも樹木の葉に由来するものである場合には、モノテルペンやセスキテルペン等の成分が多く含まれるため好ましい。 It is more preferable that the material used in this embodiment is at least derived from the leaves of a tree. "At least derived from the leaves of a tree" means that the material contains components or parts derived from the leaves of the tree, and "at least derived from the leaves of the tree" means that the material further contains components or parts derived from the xylem of the tree. May include. The fact that the material is at least derived from the leaves of the tree is confirmed by the fact that the material contains a green or blue portion derived from the chloroplast, for example, when the material is observed with an optical microscope. be able to. When the material is at least derived from the leaves of a tree, it is preferable because it contains a large amount of components such as monoterpenes and sesquiterpenes.

These tree raw materials are widely distributed in Japan and are preferably used because they are easily available.
当該材料は、生木である樹木の木質部および／または葉から精油および水分の少なくとも一部が除去されたものであるが、精油が完全に取り除かれず、一部が当該材料に残っていてもよい。その場合、当該精油は、当該材料の消臭機能に資することがある。 The material is obtained by removing at least a part of essential oil and water from the xylem and / or leaves of a raw tree, but the essential oil may not be completely removed and a part may remain in the material. .. In that case, the essential oil may contribute to the deodorizing function of the material.
当該材料に存在する精油は、モノテルペンやセスキテルペン等の成分が含まれることが好ましく、具体的には、α－ピネン、β－ピネン、カンフェン、サンテン、トリシクレン、β－カリオフィレン、ミルセン、アロオシメン、イソプレン、オシメン、ピロネン、クリプトテネン、β-フェランドレン、２，４（８）－ｐ－メンタジエン、メノゲレン、セスキシトロネン、ジンギベレン、サビネン、３，８（９）－ｐ－メンタジエン、テルピネン－４－オール、シトロネラール、ボルニルアセテート、α－テルピネオール、δ－３－カレン、テルピノレン、γ－テルピネンおよび１,８－シネオールから選ばれる少なくとも１種の成分を含むことが好ましい。 The essential oil present in the material preferably contains components such as monoterpenes and sesquiterpenes, specifically, α-pinene, β-pinene, kanfen, santene, tricyclene, β-cariophyllene, myrcene, aloosimene, etc. Isoprene, ossimen, myrcene, cryptotenen, β-ferrandren, 2,4 (8) -p-mentadiene, menogelene, sesxitronen, gingiberen, sabinen, 3,8 (9) -p-mentadiene, terpinene-4-ol, It preferably contains at least one component selected from citronellal, bornyl acetate, α-terpineol, δ-3-calene, terpinolene, γ-terpinene and 1,8-cineole.
当該材料に存在する精油は、好ましくは揮発性が低いおよび／または不揮発性である。揮発性が低いほど、より長い期間にわたって精油の機能（例えば、消臭機能および／または芳香機能）が発揮されるからである。また、精油成分は比較的分子量の大きい成分を含むことが好ましい。分子量が大きいほど、揮発しにくいからである。樹木の木質部等から精油を抽出すると、より分子量が小さい、および／または揮発しやすい精油が優先的に抽出されるため、当該材料には揮発性の低い、および／または分子量のより大きい精油が残る傾向ある。当該材料に残る精油成分はモノテルペンの含有量が少なく、セスキテルペン、ジテルペンまたはテトラテルペンをより多く含むことが好ましい。セスキテルペン、ジテルペンなどの分子量が大きいテルペン類の割合が大きいと、長期間にわたって消臭機能および／または芳香機能を発揮するとともに、様々な消臭機能を発揮すること、すなわち種々の臭いに対応することが可能となる。 The essential oils present in the material are preferably less volatile and / or non-volatile. This is because the lower the volatility, the longer the function of the essential oil (for example, the deodorizing function and / or the aroma function) is exhibited. Further, the essential oil component preferably contains a component having a relatively large molecular weight. This is because the larger the molecular weight, the less likely it is to volatilize. When the essential oil is extracted from the xylem of a tree, the essential oil having a smaller molecular weight and / or easily volatile is preferentially extracted, so that the essential oil having a low molecular weight and / or a larger molecular weight remains in the material. There is a tendency. The essential oil component remaining in the material preferably has a low content of monoterpenes and more preferably contains sesquiterpenes, diterpenes or tetraterpenes. When the proportion of terpenes having a large molecular weight such as sesquiterpenes and diterpenes is large, the deodorant function and / or the fragrance function is exhibited for a long period of time, and various deodorant functions are exhibited, that is, various odors are dealt with. Is possible.
当該材料は、一般に、消臭機能および／または芳香機能を発揮する。
消臭機能を有する吸収材が排泄用吸収性物品に使用される場合には、排泄物に由来する臭いを軽減することができる。当該材料は、好ましくは、アンモニア、硫化水素、メチルメルカプタン、酢酸、トルエン、およびホルムアルデヒドから選ばれる少なくとも１種、より好ましくはアンモニア、硫化水素、およびメチルメルカプタンから選ばれる少なくとも１種に由来する臭いを消臭し得る機能を有している。
The material generally exhibits deodorant and / or aromatic functions.
When an absorbent material having a deodorizing function is used for an absorbent article for excretion, the odor derived from the excrement can be reduced. The material preferably has an odor derived from at least one selected from ammonia, hydrogen sulfide, methyl mercaptan, acetic acid, toluene, and formaldehyde, more preferably from at least one selected from ammonia, hydrogen sulfide, and methyl mercaptan. It has a function that can deodorize.
また、当該材料が芳香機能を有する場合には、当該材料からの芳香により臭い（特に排泄物に由来する臭い）がマスキングされて、感覚的に弱められる。特に当該材料は水分で濡らされるとより強い芳香性を示して、より効果的に臭いをマスキングしやすい。したがって、吸収材に含まれる当該材料は、排泄物に含まれる水分によって濡らされると、より効果的に芳香機能を発揮できる。 When the material has an aromatic function, the odor from the material (particularly the odor derived from excrement) is masked and sensuously weakened. In particular, the material exhibits a stronger aromaticity when wetted with moisture, and is more effective in masking odors. Therefore, the material contained in the absorbent material can exert a fragrance function more effectively when it is wetted by the water contained in the excrement.
当該材料は、粉状物として吸収材に含まれていてよい。粉状物の当該材料は、より均一に吸収材に分布させることができ、吸収材全体にわたって均等に消臭機能等を発揮させることができる。あるいは、粉状物の当該材料を用いれば、吸収材の位置に応じて当該材料の使用量を調節することが比較的容易となる。例えば、吸収性物品の中央部により多くの当該材料を配置すること、あるいは中央部から周辺部にかけて使用量を漸減させる構成も、粉状物の当該材料を用いればより容易に得られる。さらに、粉状物の当該材料は、繊維とともに抄き込んで湿式不織布を構成するのに適している。 The material may be contained in the absorbent material as a powder. The powdery material can be more evenly distributed in the absorbent material, and the deodorizing function and the like can be evenly exerted over the entire absorbent material. Alternatively, if the powdery material is used, it becomes relatively easy to adjust the amount of the material used according to the position of the absorbent material. For example, a configuration in which a larger amount of the material is arranged in the central portion of the absorbent article or the amount of the material used is gradually reduced from the central portion to the peripheral portion can be more easily obtained by using the material in the form of powder. Further, the powdery material is suitable for forming a wet non-woven fabric by being squeezed together with fibers.
当該材料は、例えば、高速気流によるジェットミル、ボールミル、ハンマーミル、高圧水流を用いた湿式微粉砕装置などを用いて粉状物にすることができる。粉状物の平均粒径は１μｍ～５００μｍであることが好ましい。なお、粉状物の平均粒径は、レーザー回析・散乱式粒度分布測定装置で計測することができ、メディアン径（Ｄ５０）で表される。 The material can be made into a powder by using, for example, a jet mill with a high-speed air flow, a ball mill, a hammer mill, a wet pulverizer using a high-pressure water stream, or the like. The average particle size of the powder is preferably 1 μm to 500 μm. The average particle size of the powdery substance can be measured by a laser diffraction / scattering type particle size distribution measuring device and is represented by a median diameter (D50).

吸収コアを被覆するラップ材は、例えば、織物、編物、および不織布等の一体化された繊維集合物、またはフィルムであってよく、あるいは二以上の繊維集合物、または繊維集合物とフィルムとを含む積層シートであってよい。
More specifically, the absorption core may be a combination of crushed pulp and a polymer absorber, or may be composed of only crushed pulp or only a polymer absorber. Alternatively, the absorbent core may be a fiber aggregate such as a fiber tow, a woven or knitted fabric, or a non-woven fabric, or a film. Further, the absorbent material consisting only of the absorbent core may be an integrated fiber aggregate (particularly, a non-woven fabric), a film, or a laminate thereof. The absorbent core may be in the form of a sheet with or without a wrap material. Here, the "sheet-like material" used with respect to the absorbent material refers to a material having a main surface having a size relatively wide with respect to the thickness, for example, having a thickness of about 1 mm to 10 mm and having a rectangular main surface or a main surface. When it is a square, it is as if one side is 5 cm or more.

The absorbent material of the present embodiment preferably exhibits a deodorizing effect such that the deodorizing performance of ammonia after 10 minutes is 80% or more. The deodorizing performance of ammonia after 10 minutes is calculated by the following formula from the ammonia concentration measured by the method described in Examples described later. In the formula, A is the ammonia concentration (ppm) when the elapsed time is 0 minutes, and B is the ammonia concentration (ppm) when the elapsed time is 10 minutes.
Deodorant performance after 10 minutes of ammonia (%) = [(AB) / A] × 100

It is more preferably contained in an amount of 3 g / m 2 to 30 g / m 2 . The preferable content of the material may vary depending on the total amount of the absorbent material, but if the absorbent material contains the material in an amount within the above range, the effect of containing the material is likely to be satisfactorily exhibited. If the absolute amount of the material is too small, the deodorizing effect of the material cannot be sufficiently obtained, and if it is too large, the amount of other members constituting the absorbent material becomes small, resulting in excrement and the like. It may not be able to absorb the liquid sufficiently.

It is more preferable to occupy. When the absorbent material of the present embodiment is used for a pad, the material preferably occupies 0.1% by mass to 10% by mass, and more preferably 1% by mass to 5% by mass of the entire absorbent material.
本実施形態の吸収材が粒状物である場合、当該材料は、粒状物の１質量％～８０質量％を占めることが好ましく、５質量％～７０質量％を占めることがより好ましい。粒状物の場合、粒状物の内部に排泄物が取り込まれるため、表面だけではなく内部にも当該材料が含まれると、消臭がより効率的に行われる。そのため、吸収材が粒状物である場合には、例えばペット排泄用シートの場合と比較して、吸収材に占める当該材料の割合をより多くすることが好ましい。 When the absorbent material of the present embodiment is a granular material, the material preferably occupies 1% by mass to 80% by mass of the granular material, and more preferably 5% by mass to 70% by mass. In the case of a granular material, excrement is taken into the inside of the granular material, and therefore, if the material is contained not only on the surface but also inside, deodorization is performed more efficiently. Therefore, when the absorbent material is a granular material, it is preferable to increase the ratio of the material to the absorbent material as compared with the case of, for example, a pet excretion sheet.

なお、アンモニア濃度は検知管を用いて測定した。また、６段階臭気強度表示法に基づく臭気強度、および９段階快・不快度表示法に基づく快・不快の評価基準は以下のとおりである。
(evaluation)
The absorbent materials of Example 1 and Comparative Example 1 were evaluated as follows.
(Deodorant)
A 10 cm × 10 cm sample was cut out from the absorbent and placed in a 1 liter Tedlar bag. Further, 0.4 ml of 0.2% ammonia water (ammonia concentration 500 ppm at 0 minutes elapsed) was added dropwise to the sample in the tedler bag, and 1) ammonia concentration, 2) odor intensity based on the 6-step odor intensity display method, and 3) Time-dependent changes in comfort / discomfort based on the 9-step comfort / discomfort display method were confirmed. The results are shown in Table 1.
The ammonia concentration was measured using a detector tube. The odor intensity based on the 6-step odor intensity display method and the evaluation criteria for comfort / discomfort based on the 9-step pleasant / unpleasant degree display method are as follows.
・６段階臭気強度表示法

実施例１と比較例１の結果から、トドマツの粉状物が優れたアンモニア消臭機能を発揮することが確認された。例えば経過時間が１０分の時、実施例１のアンモニア濃度は比較例１のアンモニア濃度の約半分となっており、消臭能力が高いことがわかる。経過時間が１０分の時、実施例１のアンモニアの消臭性能は８８％であり、比較例１のアンモニアの消臭性能は７８％であった。また、実施例１の経過時間が１０分の時のアンモニア濃度と、比較例１の経過時間が３０分の時のアンモニア濃度は同じ６ｐｐｍだったが、実施例１の快・不快度は＋１であるのに対し、比較例１は－１であった。これはトドマツ粉状物の芳香性によるマスキング効果によると考えられる。 From the results of Example 1 and Comparative Example 1, it was confirmed that the powdered Abies sachalinensis exerts an excellent ammonia deodorizing function. For example, when the elapsed time is 10 minutes, the ammonia concentration of Example 1 is about half of the ammonia concentration of Comparative Example 1, indicating that the deodorizing ability is high. When the elapsed time was 10 minutes, the deodorizing performance of ammonia in Example 1 was 88%, and the deodorizing performance of ammonia in Comparative Example 1 was 78%. Further, the ammonia concentration when the elapsed time of Example 1 was 10 minutes and the ammonia concentration when the elapsed time of Comparative Example 1 was 30 minutes were the same 6 ppm, but the degree of comfort and discomfort of Example 1 was +1. On the other hand, Comparative Example 1 was -1. It is considered that this is due to the masking effect due to the aromaticity of the Abies sachalinensis powder.

(Example 3)
60 parts by weight of the powdery material obtained in Production Example 1 and 40 parts by weight of bentonite powder are mixed, 30 parts by weight of water is added and kneaded, and the mixture is formed into columnar particles having a diameter of 3 mm by a granulator and dried. The cat litter of Example 3 was obtained by drying with a machine. The following deodorant property evaluation was performed on the cat litter of Example 3.
（消臭性）
直径１０ｃｍ、高さ１０ｃｍの円筒形容器に、容器の内容量の半分に相当する猫砂を入れ、０．２％アンモニア水を０．５ｍｌ滴下し、滴下から３０分後の臭いを確認した。
(Deodorant)
Cat litter, which corresponds to half of the content of the container, was placed in a cylindrical container having a diameter of 10 cm and a height of 10 cm, 0.5 ml of 0.2% ammonia water was added dropwise, and the odor was confirmed 30 minutes after the addition.
実施例３の猫砂について消臭性を確認したところ、不快な臭いは感じられなかった。 When the deodorant property of the cat litter of Example 3 was confirmed, no unpleasant odor was felt.
（実施例４）
製造実施例１で得た粉状物２０重量部、水１００重量部からなる懸濁液を準備した。目付１５ｇ／ｍ２の主に木材パルプから成る湿式不織布の表面に前記懸濁液を塗布し、乾燥機で乾燥させて目付２０ｇ／ｍ２の実施例４のシート状の吸収材を得た。
(Example 4)
A suspension consisting of 20 parts by weight of the powdery substance and 100 parts by weight of water obtained in Production Example 1 was prepared. The suspension was applied to the surface of a wet nonwoven fabric mainly made of wood pulp having a grain size of 15 g / m 2 and dried in a dryer to obtain a sheet-shaped absorbent material having a grain size of 20 g / m 2 of Example 4.
実施例４のシート状吸収材に対し、実施例２と同様の吸液性試験を行ったところ、吸液時間、ウェットバック量、および拡散面積については、吸収性物品として使用するのに問題のない吸液性能を確保できることが確認された。 When the same liquid absorption test as in Example 2 was performed on the sheet-shaped absorbent material of Example 4, the liquid absorption time, the amount of wet back, and the diffusion area were problematic for use as an absorbent article. It was confirmed that no liquid absorption performance can be ensured.
（実施例５）
製造実施例１で得た粉状物１０重量部、叩解機にかけた木材パルプ８７重量部、ビニロン３重量部を用いて湿式抄紙用スラリーを調製した。このスラリーを、金網抄紙ワイヤーを用いて抄紙することにより、同ワイヤー上に紙層を形成させ、サクションボックスを用いて前記紙層を脱水した後、前記紙層をドライヤーで乾燥させた。これにより、粉状物が抄き込まれた湿式不織布である、実施例５のシート状の吸収材を得た。実施例５のシート状吸収材の目付は、２５ｇ／ｍ２であった。実施例５のシート状吸収材について、硫化水素、メチルメルカプタンの消臭性評価を以下に示す方法で行った。結果を表４に示す。
(Example 5)
A slurry for wet papermaking was prepared using 10 parts by weight of the powdery material obtained in Production Example 1, 87 parts by weight of wood pulp subjected to a beating machine, and 3 parts by weight of vinylon. This slurry was made into paper using a wire mesh papermaking wire to form a paper layer on the wire, the paper layer was dehydrated using a suction box, and then the paper layer was dried by a dryer. As a result, a sheet-shaped absorbent material of Example 5, which is a wet non-woven fabric in which a powdery substance was extracted, was obtained. The basis weight of the sheet-shaped absorbent material of Example 5 was 25 g / m 2 . The deodorant properties of hydrogen sulfide and methyl mercaptan were evaluated for the sheet-shaped absorbent material of Example 5 by the method shown below. The results are shown in Table 4.
（消臭性評価）
シート状吸収材を１０ｃｍ×１０ｃｍに切り出し、５リットルのテドラーバッグに入れた。このテドラーバッグ内に、硫化水素を３リットル注入し（経時時間０時間で硫化水素濃度４．０ｐｐｍ）、表４に示す時間が経過したときに、硫化水素濃度を検知管を用いて測定した。また、硫化水素をメチルメルカプタンに変えて（経時時間０時間でメチルメルカプタン濃度８．０ｐｐｍ）、同様にメチルメルカプタン濃度の経時変化を測定した。
(Deodorant evaluation)
The sheet-shaped absorbent material was cut into 10 cm × 10 cm pieces and placed in a 5 liter Tedlar bag. 3 liters of hydrogen sulfide was injected into this tedler bag (hydrogen sulfide concentration was 4.0 ppm at 0 hour of time), and when the time shown in Table 4 had elapsed, the hydrogen sulfide concentration was measured using a detector tube. Further, hydrogen sulfide was changed to methyl mercaptan (methyl mercaptan concentration 8.0 ppm over time), and the change in methyl mercaptan concentration with time was measured in the same manner.
実施例５の結果から、実施製造例１で製造された粉状物が優れた消臭機能を発揮することが確認された。 From the results of Example 5, it was confirmed that the powdery substance produced in Example 1 exhibited an excellent deodorizing function.
