Description

本発明は、ウェットシートに関する。 The present invention relates to a wet sheet.

手の汚れの除去や清掃等に用いられる除菌効果を有するウェットシートとしては、大別して、含浸させる薬液にアルコールが含まれるものと、含まれないものとがあるが、従来、アルコールが含まれないものにおいては、除菌活性値を向上するために、プロピレングリコール及びパラベンを使用していた。しかし、プロピレングリコール及びパラベンを使用すると、薬液が使用者の肌に付着した際にべたつきを感じることがあった。
そこで、薬液にアルコールが含まれず、かつプロピレングリコール及びパラベンを使用しない、除菌効果を有するウェットシートが知られている（例えば、特許文献１参照）。 Wet wipes with a sterilizing effect used for removing stains on hands and cleaning are roughly classified into those containing alcohol and those not containing alcohol in the chemical solution to be impregnated, but conventionally, alcohol is contained. In those without, propylene glycol and paraben were used to improve the sterilization activity value. However, when propylene glycol and paraben were used, the drug solution sometimes felt sticky when it adhered to the user's skin.
Therefore, there is known a wet sheet having a sterilizing effect, which does not contain alcohol in the chemical solution and does not use propylene glycol and paraben (see, for example, Patent Document 1).

以下、本発明の実施形態であるウェットシートについて詳細に説明する。ただし、本発明の技術的範囲は、これに限定されるものではない。 Hereinafter, the wet sheet according to the embodiment of the present invention will be described in detail. However, the technical scope of the present invention is not limited to this.

［実施形態の構成］
｛全体構成｝
本実施形態のウェットシートは、シート体に薬液が含浸されたものである。 [Structure of Embodiment]
{overall structure}
The wet sheet of the present embodiment is a sheet body impregnated with a chemical solution.

｛シート体｝
本発明において用いるシート体としては、後述の薬液を含浸させることができるものであれば、特に限定はないが、柄のない不織布であり、かつ引張強度（長辺１００ｍｍ、短辺５０ｍｍの試験片を長辺方向に引っ張り、これが破断したときの最大点荷重によって測定した値（株式会社エー・アンド・ディー製のTENSILON RTG－1210を用いた。））が、抄紙機上の紙の進行方向（ＭＤ方向）に４５Ｎ以上であり、抄紙機上の紙の進行方向と直角な方向（ＣＤ方向）に１０Ｎ以上であることが望ましい。 {Sheet body}
The sheet body used in the present invention is not particularly limited as long as it can be impregnated with the chemical solution described later, but is a non-woven fabric without a handle and a test piece having a tensile strength (long side 100 mm, short side 50 mm). Is pulled in the long side direction, and the value measured by the maximum point load when it breaks (using TENSILON RTG-1210 manufactured by A & D Co., Ltd.) is the traveling direction of the paper on the paper making machine (. It is desirable that it is 45 N or more in the MD direction) and 10 N or more in the direction perpendicular to the traveling direction of the paper on the paper making machine (CD direction).

また、シート体を構成する原料繊維としては、レーヨン、ＰＥＴ（ポリエチレンテレフタレート）等を用いたものであることが望ましい。 Further, it is desirable that rayon, PET (polyethylene terephthalate) or the like is used as the raw material fiber constituting the sheet body.

また、シート体の目付は、２０～８０ｇｓｍであることが好ましい。なお、目付は、ＪＩＳ Ｐ ８１２４：２０１１に従って測定した坪量をいう。 The basis weight of the sheet body is preferably 20 to 80 gsm. The basis weight refers to the basis weight measured according to JIS P 8124: 2011.

｛薬液｝
薬液としては、以下のものを用いる。
なお、薬液含浸率は５０質量％以上、４００質量％以下であることが好ましい。なお薬液含浸率とは、薬液含浸前のシート体の質量と、含浸させる薬液の質量とを測定し、薬液含浸前のシート体の質量に対する含浸させる薬液の質量の割合を算出したものをいう。 {Chemical solution}
The following chemicals are used.
The chemical impregnation rate is preferably 50% by mass or more and 400% by mass or less. The chemical impregnation rate is obtained by measuring the mass of the sheet body before the chemical solution impregnation and the mass of the chemical solution to be impregnated, and calculating the ratio of the mass of the chemical solution to be impregnated to the mass of the sheet body before the chemical solution impregnation.

薬液としては接触角が４３°以下のものを用いる。接触角が３６°以下のものを用いることがさらに好ましい。
なお、接触角は、固液界面解析システム（協和界面科学株式会社のDrop Master 300）を用いて液滴法にて測定を行った。具体的には、上記システムに付属のシリンジを用いて、液滴をアルミ製の台の表面に接触させて着滴させた後、自動的にパソコンに取得した画像の解析を行い、接触角を算出した。 As the chemical solution, one having a contact angle of 43 ° or less is used. It is more preferable to use one having a contact angle of 36 ° or less.
The contact angle was measured by the sessile drop method using a solid-liquid interface analysis system (Drop Master 300 of Kyowa Interface Science Co., Ltd.). Specifically, using the syringe attached to the above system, the droplets are brought into contact with the surface of an aluminum table to be deposited, and then the image acquired on the personal computer is automatically analyzed to determine the contact angle. Calculated.

また、清掃時の除菌効果を十分なものとするため、除菌力が９９％以上である必要がある。
なお、ここで除菌力が９９％以上とは、大腸菌及び黄色ブドウ球菌の両者に対して、除菌活性値が２．０以上であることをいう。なお、除菌活性値の測定は、一財社団法人 日本衛生材料工業連合会編、「ウエットワイパー類の除菌性能試験方法」（平成27年11月16日改定）に準じて行った。
具体的には、適当な汚れと共に細菌を試験担体（ステンレス板）に接種し、乾燥後拭取り装置に設置する。試験試料（ウエットワイプまたは対照液を塗布した綿布）を巻きつけたおもりで試験担体上を所定回数拭取り、5分間静置する。5分後、試験担体を不活性化剤に移し、試験試料の細菌の増殖を抑制したり死滅させる性質を不活性化させた後、試験担体上の生菌数を測定する。
試験試料の除菌活性値は、対照試料及び試験試料で拭取り後、それぞれの試験担体上に残存する生菌数の常用対数値の差で示す。 Further, in order to make the sterilizing effect at the time of cleaning sufficient, the sterilizing power needs to be 99% or more.
Here, the sterilizing power of 99% or more means that the sterilizing activity value is 2.0 or more with respect to both Escherichia coli and Staphylococcus aureus. The sterilization activity value was measured according to "Test method for sterilization performance of wet wipers" edited by Japan Sanitary Materials Industry Association (revised on November 16, 2015).
Specifically, the test carrier (stainless steel plate) is inoculated with bacteria together with appropriate stains, dried, and then installed in a wiping device. Wipe the test carrier a predetermined number of times with a weight wrapped with a test sample (wet wipe or cotton cloth coated with a control solution), and let stand for 5 minutes. After 5 minutes, the test carrier is transferred to an inactivating agent to inactivate the properties of the test sample that suppress or kill the growth of bacteria, and then the viable cell count on the test carrier is measured.
The sterilization activity value of the test sample is shown by the difference in the common logarithmic value of the viable cell count remaining on each test carrier after wiping with the control sample and the test sample.

このような薬液としては、具体的には、例えば以下の６成分を含有し、これら６成分の含有量の合計が1.0質量％以下であり、水の含有量が99.0質量％以上であるものを用いることができる。
1.0×10-2質量％以上、5.0×10-2質量％以下のグレープフルーツ種子エキス
1.0×10-3質量％以上、5.0×10-3質量％以下のクエン酸
1.0×10-3質量％以上、5.0×10-3質量％以下のクエン酸ナトリウム
1.0×10-2質量％以上、5.0×10-1質量％以下の塩化ベンザルコニウム
1.0×10-2質量％以上、5.0×10-2質量％以下の塩化セチルピリジニウム
1.0×10-3質量％以上、5.0×10-2質量％以下のポリアミノプロピルビグアニド Specifically, such a chemical solution contains, for example, the following 6 components, the total content of these 6 components is 1.0% by mass or less, and the water content is 99.0% by mass or more. Can be used.
Grapefruit seed extract of 1.0 × 10 -2 % by mass or more and 5.0 × 10 -2 % by mass or less
Citric acid of 1.0 × 10 -3 % by mass or more and 5.0 × 10 -3 % by mass or less

｛実施形態の効果｝
十分な除菌効果を有するウェットシートを、アルコールを含有しない薬液を用いて製作した場合、従来のものにおいては、使用者が感じるべたつきを十分に低減できなかった。
これに対して、本実施形態によれば、薬液の接触角が上記の範囲であることによって、使用者の手肌等に付着した薬液が広がり易くなり、アルコールを含有せずとも、これが蒸発し易くなる。
したがって、アルコールを含有しない薬液を用いた場合においても、十分な除菌効果を有しつつ、使用者が感じるべたつきを低減することが可能となる。 {Effect of embodiment}
When a wet sheet having a sufficient sterilizing effect was produced using a chemical solution containing no alcohol, the conventional one could not sufficiently reduce the stickiness felt by the user.
On the other hand, according to the present embodiment, when the contact angle of the chemical solution is in the above range, the chemical solution adhering to the user's hand skin or the like is likely to spread, and the chemical solution evaporates even if it does not contain alcohol. It will be easier.
Therefore, even when a chemical solution containing no alcohol is used, it is possible to reduce the stickiness felt by the user while having a sufficient sterilizing effect.

次に、本発明の実施例及び比較例に係るウェットシートにつき、除菌力の評価、接触角測定及びべたつき等に関する評価を行った結果について説明する。 Next, the results of evaluation of the sterilizing power, measurement of the contact angle, stickiness, etc. of the wet sheets according to the examples and comparative examples of the present invention will be described.
