Therefore, the diaper 1 can exhibit the effect (for example, skin care function etc.) of the Chinese medicine material with respect to a wearer's skin. This effect can be maintained even after the diaper 1 is supplied with the liquid excrement of the wearer. That is, since the liquid excrement of the wearer supplied to the diaper 1 quickly passes through the top sheet 2 and moves to the absorbent body 4, the herbal medicine material layer 5 formed on the top sheet 2 and the liquid excrement The contact state does not continue. Therefore, the diaper 1 can prevent a decrease in the efficacy of the traditional Chinese medicine material due to the continuation of the contact state with the liquid excrement.

- the second sheet is a liquid-permeable sheet that allows the liquid excrement of the wearer to pass through.
- the liquid permeable sheet include a nonwoven fabric, a woven fabric, a synthetic resin film in which liquid permeable holes are formed, a net-like sheet having a mesh, and the material, thickness, basis weight, density, etc. are liquid of the wearer. It can adjust suitably in the range which excrement can permeate
- the second sheet is preferably an air-through nonwoven fabric.
- the air-through nonwoven fabric is preferable in that it has a thickness sufficient to move the absorber 4 away from the top sheet 2 toward the back sheet 3.
- a herbal medicine material layer is formed on a sheet member provided on the skin side surface other than the top sheet 2.

- Example Product The disposable diaper manufactured in Production Example 1 as “Example Product” and the commercially available disposable paper diaper that does not have a herbal medicine material layer as “Comparative Example Product” were absorbed into artificial urine (seconds) and rewet amount (g). Was measured.
- the method for producing artificial urine is as follows. ⁇ Production of artificial urine> (1) Weigh the following chemicals. ⁇ Urea 400g ⁇ 160g sodium chloride ⁇ Magnesium sulfate (7 hydrate) 16g ⁇ Calcium chloride (dihydrate) 6g (2) Accumulate 10 L of tap water in a plastic tank. (3) Put 1500 mL of tap water in a 2 L beaker. (4) Put 400 g of urea in the beaker of (3) and stir until dissolved. (5) Put the contents of the beaker of (4) into the plastic tank. (6) Add 1000 mL of tap water to the beaker emptied in (5). (7) Put 160 g of sodium chloride into the beaker of (6) and stir until dissolved.

(3) Fix the sample. (4) The burette is fixed at a position 10 mm above the artificial urine dropping position. (5) Remove the burette and place a cylinder (diameter 60 mm, weight 200 g) on the sample so that the artificial urine dropping position mark is in the center.
- Table 1 shows the measurement results of absorption rate (seconds) and rewet amount (g).
- the absorption rate of the example product was not inferior to the absorption rate of the comparative product. This result shows that when the artificial urine passes through the top sheet, the herbal medicine material layer formed on the top sheet is less likely to be a barrier, and the reduction of the liquid absorption rate is prevented. Moreover, as shown in Table 1, the rewet amount of the example product was significantly smaller than the rewet amount of the comparative example product. This result shows that the traditional Chinese medicine material layer formed on the top sheet has an anti-rewetting action.

Abstract
Description
また、態様1によれば、漢方薬材料層が両親媒性物質をバインダーとして含有することにより、次の作用効果を発揮させることができる。漢方薬材料層のトップシートへの固着強度が増加するので、液体がトップシートを透過する際に、漢方薬材料層がトップシートから脱落しにくい。また、液体がトップシートを透過する際に、漢方薬材料層が障壁となりにくいので、液体吸収速度の低減を防止することができる(実施例参照)。なお、前者の効果は、主として、両親媒性物質の疎水性に起因し、後者の効果は、主として、両親媒性物質の親水性に起因する。さらに、吸収性物品への加圧(例えば、着用者の体重による加圧)によって吸収体に吸収・保持されている液体がトップシートへ後戻りする際、漢方薬材料層が障壁となるので、リウェット(吸収体に吸収・保持されている液体のトップシートからの染み出し)を防止することができる(実施例参照)。
以下、使い捨てオムツを例として、本発明の吸収性物品の実施形態を説明する。
図1~図3に示すように、トップシート2は、オムツ1の肌側表面に設けられている。トップシート2は、着用者の液状排泄物が透過可能な液透過性シートである。液透過性シートとしては、例えば、不織布、織布、液体透過孔が形成された合成樹脂フィルム、網目を有するネット状シート等が挙げられ、材料、厚み、目付、密度等は、着用者の液状排泄物が透過可能な範囲で適宜調整することができる。
図1~図3に示すように、バックシート3は、オムツ1の着衣側表面に設けられている。バックシート3は、吸収体4に吸収・保持される液状排泄物の漏れを防止可能な液不透過性シートである。バックシート3は、着用時のムレを低減させるために、液不透過性に加えて、通気性又は透湿性を有することが好ましい。液不透過性シートとしては、例えば、防水処理を施した不織布(例えば、ポイントボンド不織布、スパンボンド不織布、スパンレース不織布等)、合成樹脂(例えば、ポリエチレン、ポリプロピレン、ポリエチレンテレフタレート等)フィルム、不織布と合成樹脂フィルムとの複合シート等が挙げられ、材料、厚み、目付、密度等は、吸収体4に吸収・保持される液状排泄物の漏れを防止可能な範囲で適宜調整することができる。
図2に示すように、吸収体4は、前面部11から中間部12を通じて後面部13に至るように配置されている。吸収体4に含有される吸収性材料は、着用者の液状排泄物を吸収・保持可能である限り特に限定されない。吸収性材料としては、例えば、吸水性繊維、高吸水性材料(例えば、高吸水性樹脂、高吸水性繊維等)が挙げられる。吸収性材料層は、ブロッキング防止剤、紫外線吸収剤、増粘分岐剤、艶消剤、着色剤、その他の各種改良剤を含有してもよい。
図1~図3に示すように、漢方薬材料層5は、トップシート2のうち吸収体4の配置領域に形成されている。これにより、トップシート2には、漢方薬材料層5に含まれる漢方薬材料に基づく機能が付与されている。また、漢方薬材料が着用者の肌に届きやすいので、着用者の肌に対する漢方薬材料の効能(例えば、スキンケア機能等)を発揮させることができる。
図1~図3に示すように、トップシート2の肌側表面には、液不透過性のカバーシート6が設けられている。図1~図3に示すように、カバーシート6の略中央には開口部61が形成されており、トップシート2の一部(吸収体4の配置領域の一部)は、カバーシート6の開口部61から露出し、カバーシート6とともに、オムツ1の肌側表面を構成している。
図1~図3に示すように、カバーシート6の開口部61の両側には、液不透過性シートで形成された防漏カフ7a,7bが設けられている。防漏カフ7a,7bの一方の端部は、トップシート2とカバーシート6との間に挟まれて固定された固定端であり、他方の端部は、カバーシート6の開口部61から露出する自由端である。防漏カフ7a,7bの自由端には、縦方向Yに延びる弾性部71a,71bが設けられており、防漏カフ7a,7bは、着用者の肌方向に向けて立ち上がっている。
図2及び図3に示すように、バックシート3及び吸収体4の間には、液不透過性の防漏シート8が設けられている。防漏シート8は、液不透過性シートであり、液不透過性シートとしては、例えば、防水処理を施した不織布(例えば、ポイントボンド不織布、スパンボンド不織布、スパンレース不織布等)、合成樹脂(例えば、ポリエチレン、ポリプロピレン、ポリエチレンテレフタレート等)フィルム、不織布と合成樹脂フィルムとの複合シート等が挙げられる。
図1~図3に示すように、略同一寸法の砂時計形状であるバックシート3及びカバーシート6の間には、弾性部材91,92,93,94が設けられている。なお、図1において、弾性部材91,92,93,94の一部は省略されている。
<変更例A>
変更例Aでは、トップシート2及び吸収体4の間に液透過性のセカンドシートが配置されている。これにより、着用者の液状排泄物が吸収・保持される吸収体4の位置を、オムツ1の肌側表面に位置するトップシート2からバックシート3側へ遠ざけることができるので、吸収体4に吸収・保持される液状排泄物と漢方薬材料層5との接触、及びこれに起因する漢方薬材料の効能の低減を防止することができる。
変更例Bでは、トップシート2以外の、肌側表面に設けられたシート部材に漢方薬材料層が形成されている。これにより、漢方薬材料層の形成可能な箇所が増加するので、漢方薬材料層の機能を増強・多様化することができる。なお、シート部材に形成される漢方薬材料層は、トップシート2に形成される漢方薬材料層5と同様の構成とすることができる。
漢方薬材料(紅参抽出物、陳皮抽出物、ビャクシ抽出物及び葛根抽出物)25重量%、カルボキシメチルセルロース10重量%、水5重量%、及びスチレンブタジエン共重合体60%を含む漢方薬インクを調製した。この際、カルボキシメチルセルロースを水に溶解させるために超音波処理を実施した。
