Description
本発明は、ナプキン、及びその製造方法に関する。
The present invention, Na Pukin relates to a process for the preparation of 及 benefactor.
従来、身体に装着して尿等の体液を吸収する吸収性物品には、着用側（上側）の上層シートと、非着用側（下側）の下層シートと、両シートの間に介在する吸収体と、この吸収体を覆うクレープ紙とを備えたものがある。 Conventionally, absorbent articles that are worn on the body and absorb bodily fluids such as urine include an upper layer sheet on the wearing side (upper side), a lower layer sheet on the non-wearing side (lower side), and absorption interposed between both sheets. Some have a body and crepe paper covering the absorber.
上層シートは着用者の肌にあたる装着面を有するトップシートと、トップシートの下側に配置されたセカンドシートとを備えており、両シートは着用者の体液を通過させる透液性を有している。一方、下層シートは複数枚のシートが重ね合わされて構成されており、吸収体は着用者の体液を吸収するポリマーおよびパルプ、またはポリマーのみから構成されている。またクレープ紙は着用者の体液を通過させる透液性を有しており、吸収体の形状を維持したり吸収体を構成するパルプやポリマーの飛散を防止している。 The upper layer sheet includes a top sheet having a mounting surface corresponding to the wearer's skin and a second sheet disposed on the lower side of the top sheet, and both sheets have liquid permeability that allows the body fluid of the wearer to pass therethrough. Yes. On the other hand, the lower layer sheet is formed by superimposing a plurality of sheets, and the absorbent body is composed of a polymer and pulp that absorbs the body fluid of the wearer, or a polymer alone. Further, the crepe paper has a liquid permeability that allows the body fluid of the wearer to pass therethrough, and maintains the shape of the absorbent body and prevents the pulp and polymer constituting the absorbent body from scattering.
そしてこのような吸収性物品の中には、消臭作用や抗菌作用を付与するために消臭剤や抗菌剤が添加されたものがあり、例えば消臭作用や抗菌作用を効率よく働かせるために、クレープ紙に非水溶性の消臭剤や抗菌剤を含む塗工液が塗工されたものが知られている。 And in such an absorbent article, there are those to which a deodorant or an antibacterial agent is added in order to impart a deodorant action or an antibacterial action. A crepe paper is known in which a coating liquid containing a water-insoluble deodorant or antibacterial agent is applied.
しかしながら、塗工によってクレープ紙に消臭剤や抗菌剤が固着しても、塗工量が多い場合にはクレープ紙から剥がれ落ちてしまう（粉落ち）。また塗工量を少なくした場合には粉落ちはないが、消臭作用や抗菌作用が低下してしまう問題があった。 However, even if the deodorant or antibacterial agent adheres to the crepe paper by coating, if the coating amount is large, the crepe paper peels off from the crepe paper (powder off). Further, when the coating amount is reduced, there is no powder falling, but there is a problem that the deodorizing action and the antibacterial action are lowered.
本発明は、かかる従来の課題に鑑みてなされたものであり、クレープ紙に消臭剤や抗菌剤を添加しても、消臭作用や抗菌作用を低下させずに粉落ちを防止することができるナプキン、及びその製造方法を提供することを目的とする。
The present invention has been made in view of such conventional problems, and even if a deodorant or an antibacterial agent is added to the crepe paper, the powder can be prevented from falling without reducing the deodorant action and the antibacterial action. An object of the present invention is to provide a napkin that can be produced and a method for producing the same.

本発明をより詳細に説明するために、以下添付図面に従ってこれを説明する。 In order to explain the present invention in more detail, it will be described below with reference to the accompanying drawings.
図１は、本発明の実施の形態を示す吸収性物品（ナプキン）１の分解模式縦断面図である。この吸収性物品１は、着用側（上側）の上層シート２と、非着用側（下側）の下層シート３と、両シート２、３の間に介在する吸収体４と、吸収体４を覆うクレープ紙５とを備えている。 FIG. 1 is an exploded schematic longitudinal sectional view of an absorbent article (napkin) 1 showing an embodiment of the present invention. The absorbent article 1 includes an upper layer sheet 2 on the wearing side (upper side), a lower layer sheet 3 on the non-wearing side (lower side), an absorbent body 4 interposed between both sheets 2 and 3, and the absorbent body 4. Covering crepe paper 5.
上層シート２は、着用者の肌にあたる装着面を有するトップシートと、トップシートの下側に配置されたセカンドシートとを備えている。また両シートは不織布から構成されており、着用者の体液を通過させる透液性を有している。 The upper layer sheet 2 includes a top sheet having a mounting surface corresponding to the wearer's skin, and a second sheet disposed below the top sheet. Moreover, both sheets are comprised from the nonwoven fabric, and have the liquid permeability which allows a wearer's bodily fluid to pass through.
下層シート３は、複数枚のシートが重ね合わされて構成されており、ポリエチレン等の着用者の体液を通過させない不透液性フィルムや、不透液性フィルムと不織布あるいは織布を貼り合わせた透液性の素材や、通気性また非通気性の素材が使用されている。 The lower layer sheet 3 is formed by superimposing a plurality of sheets, and is made of a liquid-impervious film that does not allow the wearer's body fluid such as polyethylene to pass through, or a liquid-impervious film and a nonwoven fabric or a woven fabric bonded together. Liquid materials and breathable or non-breathable materials are used.
吸収体４は、着用者の体液を吸収するポリマーおよびパルプ、またはポリマーから構成されており、クレープ紙は着用者の体液を通過させる透液性を有している。 The absorbent body 4 is made of a polymer and pulp that absorbs a wearer's body fluid, or a polymer, and the crepe paper has liquid permeability that allows the wearer's body fluid to pass therethrough.
以下この吸収性物品１に基づいて実施例により本発明をさらに詳しく説明するが、本発明の範囲はかかる実施例に限定されるものではない。 EXAMPLES Hereinafter, although an Example demonstrates this invention further in detail based on this absorbent article 1, the scope of the present invention is not limited to this Example.
実施例１
銀イオンを担持したゼオライトを、クレープ紙５にノンバインダーでグラビアコートにより塗工量０．６ｇ／ｍ２で塗工し、１５０℃で乾燥させた後、吸収性物品１を製造した。
Example 1
Zeolite carrying silver ions was applied to crepe paper 5 by a gravure coat with a non-binder at a coating amount of 0.6 g / m 2 and dried at 150 ° C., and then absorbent article 1 was produced.
比較例１
銀イオンを担持したゼオライトを、クレープ紙５にノンバインダーでグラビアコートにより塗工量０．１ｇ／ｍ２で塗工し、１５０℃で乾燥させた後、吸収性物品１を製造した。
Comparative Example 1
Zeolite carrying silver ions was applied to crepe paper 5 by a gravure coat with a non-binder at a coating amount of 0.1 g / m 2 and dried at 150 ° C., and then absorbent article 1 was produced.
比較例２
銀イオンを担持したゼオライトを、クレープ紙５にノンバインダーでグラビアコートにより塗工量１．２ｇ／ｍ２で塗工し、１５０℃で乾燥させた後、吸収性物品１を製造した。
Comparative Example 2
Zeolite carrying silver ions was applied to crepe paper 5 by a gravure coat with a non-binder at a coating amount of 1.2 g / m 2 and dried at 150 ° C., and then absorbent article 1 was produced.
またブランクとして何も塗工せずに吸収性物品１を製造した。 Moreover, the absorbent article 1 was manufactured without coating anything as a blank.
各吸収性物品１の吸収性能の測定は、表面液流れ測定法と透液性測定法により行った。表面液流れ測定法は、サンプルをＭＤ方向に切り取り、４５度の傾斜を有する傾斜部材の傾斜面に濾紙を１０枚重ねて貼り付け、その上にサンプルを肌にあたる方を上にして貼り付ける。そして高さ１０ｍｍより１０ｍｌピペットで着色した人工尿を目印をつけた箇所に１滴落とし、表面上のＭＤ方向に液滴が流れた長さを測定した。 The absorption performance of each absorbent article 1 was measured by a surface liquid flow measurement method and a liquid permeability measurement method. In the surface liquid flow measurement method, a sample is cut in the MD direction, 10 filter papers are stacked on the inclined surface of an inclined member having an inclination of 45 degrees, and the sample is attached with the one facing the skin facing up. One drop of artificial urine colored with a 10 ml pipette from a height of 10 mm was dropped on the marked area, and the length of the droplet flowing in the MD direction on the surface was measured.
また透液性測定法は、サンプルを１００ｍｍ×１００ｍｍに切り取り、４０枚重ねにして四隅をホチキスで固定する。そして、サンプルを肌にあたる方を下側にして人工尿に浮かべ、表面中央が完全に人工尿に浸透するまでの時間を測定した。 In the liquid permeability measurement method, a sample is cut into a size of 100 mm × 100 mm, 40 sheets are stacked, and four corners are fixed with a staple. Then, the sample was floated on the artificial urine with the side facing the skin down, and the time until the center of the surface completely penetrated into the artificial urine was measured.
また粉落ちの測定は、サンプルを１０ｃｍ×１０ｃｍに切り取ったものを１０枚重ねて黒色板の５０ｃｍ上方から落下させる。これを１０回繰り返し、粉落ちの有無を目視にて確認した。 さらに消臭作用や抗菌作用の測定は人工尿を使用して官能検査（におい）により行った。 In addition, the measurement of powder fall is performed by dropping 10 samples of 10 cm × 10 cm and dropping from 50 cm above the black plate. This was repeated 10 times, and the presence or absence of powder falling was confirmed visually. Furthermore, the deodorant action and the antibacterial action were measured by sensory test (odor) using artificial urine.
なお人工尿の組成は、尿素２ｇ、塩化ナトリウム０．８０ｇ、塩化カルシウム２水和物０．０８ｇ、硫酸マグネシウム２水和物０．０３ｇ、イオン交換水９７．０９ｇとした。 The composition of the artificial urine was 2 g of urea, 0.80 g of sodium chloride, 0.08 g of calcium chloride dihydrate, 0.03 g of magnesium sulfate dihydrate, and 97.09 g of ion-exchanged water.
実施例、比較例、ブランクの測定結果を表１に示す。表１における評価は、○は良、△はやや不良、×は不良である。
この表１において、実施例１は吸収性能の低下が見られず、また粉落ち無し、消臭・抗菌作用も良好であった。しかしながら、比較例１では、実施例１と同様に吸収性能の低下がみられず、また粉落ちもみられないが、消臭・抗菌作用がやや不良であった。さらに比較例２では、消臭・抗菌作用は良好であったが、実施例１に比べて吸収性能の大幅な低下がみられ、また粉落ちもみられた。 In Table 1, Example 1 showed no decrease in absorption performance, no powder omission, and good deodorant / antibacterial action. However, in Comparative Example 1, as in Example 1, no reduction in absorption performance was observed, and no powder fall-off was observed, but the deodorant / antibacterial action was somewhat poor. Further, in Comparative Example 2, the deodorant / antibacterial action was good, but a significant decrease in the absorption performance was observed as compared with Example 1, and powder falling was also observed.
このように本実施例１では、銀イオンを担持したゼオライトをノンバインダー（バインダーを使用しない）でクレープ紙５に塗工することから、体液がクレープ紙を通過する際には阻害するものがなく、吸収体４に体液を十分に吸収させることができる。よって、クレープ紙５に消臭剤および抗菌剤を添加しても吸収性能の低下を防止することができる。また銀イオンを担持したゼオライトの塗工量Ｎを０．１ｇ／ｍ２＜Ｎ＜１．２／ｍ２の範囲にある０．６ｇ／ｍ２に設定したことにより、消臭・抗菌作用を低下させずに粉落ちを防止することができる。 Thus, in this Example 1, since the zeolite carrying silver ions is applied to the crepe paper 5 with a non-binder (no binder is used), there is nothing to inhibit when the body fluid passes through the crepe paper. The body fluid can be sufficiently absorbed by the absorber 4. Therefore, even if a deodorant and an antibacterial agent are added to the crepe paper 5, it is possible to prevent a decrease in absorption performance. In addition, the coating amount N of the zeolite carrying silver ions is set to 0.6 g / m 2 in the range of 0.1 g / m 2 <N <1.2 / m 2. Powder fall can be prevented without lowering.
