発明の詳細な説明Detailed Description of the Invention
 特許文献1には、ジアルキルエーテルとノニオン界面活性剤を含有するクレンジング化粧料が記載されているが、ノニオン界面活性剤の含有量が多いため、製品中から油が放出されるまでに時間がかかり、マスカラ汚れとのなじみが遅く、また、洗浄後の肌も油性感が残るものであった。特許文献2には、特定のポリオールと油剤を含有するクレンジング組成物が記載されているが、使用後の肌の油性感の点で、満足できるものではなかった。また、特許文献3には、揮発性油、不揮発性油、親水性非イオン性界面活性剤と増粘剤を含有したクレンジング化粧料が記載されているが、使用後の肌の感じが満足できるものではなかった。 Patent Document 1 describes a cleansing cosmetic containing a dialkyl ether and a nonionic surfactant. However, since the content of the nonionic surfactant is large, it takes time until oil is released from the product. The familiarity with the mascara stain was slow, and the skin after washing remained oily. Patent Document 2 describes a cleansing composition containing a specific polyol and an oil, but it was not satisfactory in terms of the oily feeling of the skin after use. Patent Document 3 describes a cleansing cosmetic containing a volatile oil, a non-volatile oil, a hydrophilic nonionic surfactant and a thickening agent, but the skin feeling after use can be satisfied. It was not a thing.
 このように、従来のクレンジング剤では、洗浄力が不十分であり、さらに、使用後の肌に油性感が残るなど、感触の点で課題があった。
 本発明は、ウォータープルーフマスカラなどの落ちにくいメイクも十分に落とすことができ、使用後の肌の感触が良好な皮膚洗浄剤組成物に関する。
Thus, the conventional cleansing agents have problems in terms of feel, such as insufficient detergency and further leaving an oily feeling on the skin after use.
The present invention relates to a skin cleanser composition capable of sufficiently removing difficult makeup such as waterproof mascara and having good skin feel after use.
 また、従来の洗浄シートでは、洗浄力が不十分であり、安定性の点でも課題があった。特に、皮膚洗浄シートとした場合には、落ちにくいメイクを十分に落とすことができず、皮膚を拭き取ったときの感触や、安定性に課題があった。
 本発明は、ウォータープルーフマスカラなどの落ちにくいメイクも十分に落とすことができ、皮膚を拭き取ったときの感触や安定性に優れた皮膚洗浄シートに関する。
Further, the conventional cleaning sheet has insufficient cleaning power, and there is a problem in terms of stability. In particular, when a skin cleaning sheet is used, it is impossible to remove makeup that is difficult to remove, and there are problems with the feel and stability when the skin is wiped off.
The present invention relates to a skin cleansing sheet that can sufficiently remove difficult makeup such as a waterproof mascara and has excellent feel and stability when the skin is wiped off.
 本発明者らは、液状のエーテル油と、特定の水溶性ポリマー、炭化水素油を特定の割合で組み合わせて用いれば、ウォータープルーフマスカラなどの落ちにくいメイクも十分に落とすことができ、使用後の肌が吸いつくような感じとなり、その感じが持続する皮膚洗浄剤組成物が得られることを見出した。肌が吸いつく感じとは、使用後の肌を手で触った時に手に吸い付くような感じがあり、上滑りしない感じのことである。 The inventors of the present invention can sufficiently remove difficult makeup such as a waterproof mascara by using a liquid ether oil, a specific water-soluble polymer, and a hydrocarbon oil in combination at a specific ratio. It has been found that a skin cleansing composition can be obtained in which the skin feels like sticking and the feeling is sustained. The feeling that the skin sticks is that it feels like it sticks to the hand when the skin after use is touched with a hand, and does not slide up.
 また、本発明者らは、密度の異なる層構造の不織布に、特定粘度のO/W型乳化物を含浸させれば、上記課題を解決した皮膚洗浄シートが得られることを見出した。 The inventors have also found that a skin cleansing sheet that solves the above problems can be obtained by impregnating a non-woven fabric having a layer structure with different densities with an O / W emulsion having a specific viscosity.
 本発明の皮膚洗浄剤組成物は、ウォータープルーフマスカラなどの落ちにくいメイクに対しても高い洗浄力が得られ、油性感が感じられずさっぱりとした感触で、使用後の肌が吸いつくような感じとなり、しっとり感が得られ、その感触が持続する。 The skin cleanser composition of the present invention provides high cleaning power even for makeup that is difficult to fall off, such as waterproof mascara, and it feels refreshing without feeling oily, so that the skin after use sticks to it. A feeling of moistness is obtained, and the feeling lasts.
 また、本発明の皮膚洗浄シートは、ウォータープルーフマスカラなどの落ちにくいメイクに対しても高い洗浄力で、さっぱり感が得られ、シートの厚み感、やわらかさ、滑らかさに優れたものである。また、皮膚洗浄シートの安定性も良好である。 In addition, the skin cleaning sheet of the present invention provides a refreshing feeling with high detergency even for makeup that is difficult to remove, such as waterproof mascara, and is excellent in sheet thickness, softness, and smoothness. The stability of the skin cleaning sheet is also good.

 また、本発明の皮膚洗浄シートで用いる不織布は、層構造を有するもので、第1層(中間層)の表面側に配置された2つの第2層(表面層)を備えるものである。また、不織布の第1層の密度と第2層の密度の比(第1層の密度/第2層の密度)は1.05以上で、不織布の第1層と第2層の一方側の厚みの比(第1層の厚み/第2層の一方側の厚み)が、0.6~1.5であり、30℃における粘度が200~15000mPa・sであるO/W型乳化物を含浸液として含むものである。
 通常、密度の高い不織布を使用した皮膚洗浄シートの場合、不織布は繊維が密に詰まっているため硬い感触で含浸液の保持量が少なくなりやすいが、ふき取り時は不織布にこしがありしっかりと拭ける。しかし、肌をやさしくふき取りたい人にとっては、不織布の硬さと洗浄液の少なさから肌へのあたりが強くなるため、好まれない場合がある。
 そこで、密度が低い不織布を使用した皮膚洗浄シートが考えられ、密度が低い不織布は繊維が疎であるため不織布自体が柔らかく変形し、滑らかに拭き取れる。しかし、繊維が疎で変形しやすいため、積層して保存した場合、含浸液がしみだしやすく、経時での品質を安定に保つことが困難なことが多い。また、ふき取りのため手に取った際や肌にシートを当てた際に含浸液が溢れ出し(かつ流れ出し)、拭き取り操作時に洗浄液が十分肌とシートの間に供されないことがある。
 そこで、本発明の皮膚洗浄シートのように、2つの密度の異なる不織布(繊維ウエブ)を組み合わせることによって含浸液の染み出し・溢れ出しが少なく、積層時の品質の安定性を保つことができ、密度の低い不織布を表面層とすることで、高洗浄力、さっぱり感が得られ、シートの厚み感、やわらかさ、滑らかさを得ることができる。ここで、「シートの厚み感」とは、拭き取り時にシートが変形し、肌あたりが柔らかくなる感じのことを示す。
The nonwoven fabric used in the skin cleaning sheet of the present invention has a layer structure, and includes two second layers (surface layers) arranged on the surface side of the first layer (intermediate layer). In addition, the ratio of the density of the first layer and the density of the second layer of the nonwoven fabric (density of the first layer / density of the second layer) is 1.05 or more, and one side of the first layer and the second layer of the nonwoven fabric. An O / W type emulsion having a thickness ratio (the thickness of the first layer / the thickness of one side of the second layer) of 0.6 to 1.5 and a viscosity at 30 ° C. of 200 to 15000 mPa · s. It is included as an impregnation liquid.
Usually, in the case of a skin cleansing sheet using a high density non-woven fabric, the non-woven fabric is densely packed and hard to hold and the amount of impregnating liquid retained tends to be small. . However, it may not be preferred for those who want to wipe the skin gently because the contact with the skin becomes stronger due to the hardness of the nonwoven fabric and the lack of cleaning liquid.
Therefore, a skin cleaning sheet using a non-woven fabric having a low density is conceivable. Since the non-woven fabric having a low density has sparse fibers, the non-woven fabric itself is softly deformed and can be wiped off smoothly. However, since the fibers are sparse and easily deformed, when they are stored in a laminated state, the impregnation liquid tends to ooze out and it is often difficult to keep the quality over time stable. In addition, the impregnating liquid overflows (and flows out) when it is picked up by hand or when the sheet is applied to the skin, and the cleaning liquid may not be sufficiently provided between the skin and the sheet during the wiping operation.
Therefore, like the skin cleaning sheet of the present invention, by combining two non-woven fabrics (fiber webs) with different densities, the impregnating liquid does not bleed out and overflow, and the stability of the quality during lamination can be maintained. By using a non-woven fabric having a low density as a surface layer, a high detergency and a refreshing feeling can be obtained, and a sheet thickness feeling, softness and smoothness can be obtained. Here, the “feel of sheet thickness” means that the sheet is deformed at the time of wiping and the skin feel becomes soft.
 本発明の皮膚洗浄シートが積層時の品質を安定に保てる理由としては、低密度の不織布を表面層とし、高密度の不織布を中間層として組み合わせているためと考えられる。皮膚洗浄シートを積層し、経時での安定性を確認すると、低密度の不織布のみに含浸液を含浸させた場合は、含浸液が上層側から下層側へしみだし、シートに保持される含浸液の量が少なくなってしまう。しかし、本発明の皮膚洗浄シートの場合、低密度の不織布である第2層(表面層)の間に高密度の不織布の第1層が組み合わさっており、高密度の不織布は繊維が密なので低密度の不織布からしみだそうとする含浸液が通り抜けにくく、さらに密度勾配が逆転する構造を有することで含浸液を下側へ移動させにくくし、その結果として品質を安定に保つことができる。 The reason why the skin cleaning sheet of the present invention can stably maintain the quality at the time of lamination is considered to be that a low density nonwoven fabric is used as a surface layer and a high density nonwoven fabric is combined as an intermediate layer. After laminating the skin cleaning sheet and confirming the stability over time, when only the low density nonwoven fabric is impregnated with the impregnating liquid, the impregnating liquid oozes out from the upper layer side to the lower layer side and is retained on the sheet The amount of will decrease. However, in the case of the skin cleaning sheet of the present invention, the first layer of the high-density nonwoven fabric is combined between the second layer (surface layer) which is a low-density nonwoven fabric, and the high-density nonwoven fabric has dense fibers. The impregnating liquid which is likely to ooze from the low density nonwoven fabric is difficult to pass through, and furthermore, the structure in which the density gradient is reversed makes it difficult to move the impregnating liquid downward, and as a result, the quality can be kept stable.
 不織布の第1層の密度と第2層の密度の比(第1層の密度/第2層の密度)は、1.05以上であり、1.1以上が好ましく、1.15以上がより好ましく、2.3以下であり、2.0以下が好ましく、1.7以下がより好ましい。また、不織布の第1層の密度と第2層の密度の比(第1層の密度/第2層の密度)は、1.05~2.3であり、1.1~2.0が好ましく、1.15~1.7がより好ましい。なお、密度は、坪量と厚み(坪量/厚み)から計算される。また、ここでの第1層と第2層の密度は、第1層と第2層を組み合わせて不織布とする前の、それぞれ単独での密度を示す。

Moreover, the thickness of each layer for calculating the density is shown as an average value of the measurement results at three locations using an enlarged photograph.
 一方、第2層は、(不織布の柔らかさと含浸液が拭き取り前に溢れ出しを抑制することによる)皮膚を拭き取ったときの摩擦が少なく、なめらかな感触及び洗浄力の点から、コットン、レーヨン、リヨセル、PET、ナイロンから選ばれる繊維で構成されるのが好ましい。また、含浸液の溢れ出しを抑制する点から、親水性繊維を多く含むことが好ましく、捻じれた繊維が作る変形が容易で戻りやすい不織布の構造による肌への当たりの柔らかさの点から、少なくともコットンを含む繊維が好ましく、コットンがより好ましい。

On the other hand, the second layer has less friction when wiping the skin (by suppressing the softness of the nonwoven fabric and the impregnating liquid before it is wiped off), and in terms of smooth feel and cleaning power, cotton, rayon, It is preferably composed of fibers selected from lyocell, PET, and nylon. In addition, from the point of suppressing the overflow of the impregnating liquid, it is preferable to contain a lot of hydrophilic fibers, from the point of softness to the skin due to the structure of a nonwoven fabric that is easily deformed and easily returned by twisted fibers, A fiber containing at least cotton is preferable, and cotton is more preferable.

The thickness of one side of the second layer of the nonwoven fabric is preferably 50 to 500 μm, more preferably 100 to 300 μm, from the viewpoints of softness, stability, and impregnating property of the cleaning liquid. The thickness of the second layer can be determined by subtracting the thickness of the first layer from the thickness of the entire sheet ((total thickness of the sheet) − (thickness of the first layer)). The thickness of one side of the second layer can be estimated as half of the calculated thickness of the second layer when the thicknesses of the two second layers are equal.
The two second layers may be the same or different.
The ratio of the thickness of one side of the first layer and the second layer of the nonwoven fabric (thickness of the first layer / thickness of the one side of the second layer) feels soft and is 0.2 to 5. 0 is preferred, 0.4 to 2.5 is more preferred, 0.5 to 2.0 is more preferred, and 0.6 to 1.5 is even more preferred.
 不織布は、第1層(中間層)の両表面にそれぞれ第2層(表面層)が配置されたものであり、3層構造であるのが好ましい。このような不織布は、水流交絡、熱エンボス加工によって各層を複合化することで製造される。
 不織布においては、よれにくさの点から、第1層と第2層の繊維が、第1層と第2層の境界で交絡しているのが好ましい。
 不織布を構成する繊維の平均繊維径は、皮膚を拭き取ったときの摩擦が少なくやわらかでなめらかな感触であり、洗浄力の点から、1~50μmが好ましく、5~30μmがより好ましい。
The non-woven fabric has a second layer (surface layer) disposed on both surfaces of the first layer (intermediate layer), and preferably has a three-layer structure. Such a nonwoven fabric is manufactured by combining each layer by hydroentanglement and heat embossing.
In the nonwoven fabric, it is preferable that the fibers of the first layer and the second layer are entangled at the boundary between the first layer and the second layer from the viewpoint of difficulty.
The average fiber diameter of the fibers constituting the non-woven fabric is preferably 1 to 50 μm, more preferably 5 to 30 μm from the viewpoint of detergency because it has a soft and smooth feel with little friction when the skin is wiped off.
 水流交絡法による複合化によってより多く形成される第1層と第2層の境界に、第1層と第2層の繊維の混合層が形成されていると、含浸液の染み出し・溢れ出しがより起きにくくなる。繊維の混合層は、一方側の混合層の厚さが、第1層と第2層の間(片側)に、第1層と二つの第2層全体のシートの厚さに対して、5~40%の割合で形成されていることが好ましく、皮膚を拭き取る際の肌へのやわらかでなめらかな感触と含浸液が拭き取り時に肌とシートの間に配されやすく、摩擦の低下、洗浄性の点から、10~35%の割合であることがより好ましい。
 また、混合層は第1層側では第1層の繊維が多くあり、第2層側で第2層の繊維が多くなるような繊維のグラデーション構造をとることが、適度な量の含浸液が肌とシートの間に供され洗浄性が高まる点から好ましい。
 なお、前述した第1層と第2層の厚さは、製造前の単層の厚さである。また、混合層の厚さは、第1層及び第2層の合計の厚さに含まれる。
When a mixed layer of fibers of the first layer and the second layer is formed at the boundary between the first layer and the second layer that are formed more by the composite by the hydroentanglement method, the impregnation liquid oozes out and overflows. Is more difficult to get up. The mixed layer of the fibers has a thickness of the mixed layer on one side of 5 between the first layer and the second layer (one side) with respect to the thickness of the sheet of the first layer and the entire two second layers. It is preferably formed at a rate of ˜40%, and the soft and smooth feel to the skin when wiping the skin and the impregnating liquid are easily disposed between the skin and the sheet at the time of wiping, reducing friction and cleaning properties. From the viewpoint, the ratio is more preferably 10 to 35%.
In addition, the mixed layer has a fiber gradation structure in which the first layer has many fibers in the first layer and the second layer has many fibers on the second layer side. This is preferable because it is provided between the skin and the sheet and the cleaning property is enhanced.
In addition, the thickness of the 1st layer and 2nd layer mentioned above is the thickness of the single layer before manufacture. Further, the thickness of the mixed layer is included in the total thickness of the first layer and the second layer.
 なお、繊維の混合層の割合は、シート断面の拡大写真から、第1層と第2層の繊維が混合している部分の厚みを混合層厚みとして計測し、断面の拡大写真の繊維の混合層厚み計測部分でのシート厚み(全体)の半値より算出する。(混合層厚み/シート厚みの半値×100(%)) In addition, the ratio of the mixed layer of the fiber is measured from the enlarged photograph of the cross section of the sheet by measuring the thickness of the portion where the fibers of the first layer and the second layer are mixed as the mixed layer thickness. It is calculated from the half value of the sheet thickness (whole) in the layer thickness measurement part. (Mixed layer thickness / half value of sheet thickness x 100 (%))
 混合層の形成は、高密度な第1層を貫通することなく水流交絡することで水流が第1層で跳ね返り分散することで広範囲に広がり層として形成できると考えるが、シートの複合が弱くなる傾向がみられることから、第1面/第2面の水流交絡後、強い水流条件でどちらか一面に水流をあてることが好ましい。強い条件での水流であっても、シート全体の密度が高められた状態となっているため、水流が第1層を貫通しにくいという利点を有する。
 また、分散したエンボス処理により部分的な複合の向上と凹凸構造化によるシートの剥がれを抑えることも好ましい。
 本発明のシートは、シートの両面側の表面に凹凸構造が付与されているのが好ましい。
The formation of the mixed layer is considered to be possible to form a wide spread layer by rebounding and dispersing the water flow in the first layer by entanglement of the water flow without penetrating the high-density first layer, but the composite of the sheet becomes weak Since a tendency is observed, it is preferable to apply a water flow to one surface under strong water flow conditions after the water flow entanglement of the first surface / second surface. Even if it is a water flow on strong conditions, since the density of the whole sheet | seat is in the state raised, it has the advantage that a water flow does not penetrate a 1st layer easily.
Further, it is also preferable to suppress the peeling of the sheet due to partial improvement in composite and uneven structure by the dispersed embossing treatment.
In the sheet of the present invention, it is preferable that a concavo-convex structure is provided on the surfaces on both sides of the sheet.
 シートの複合化において、水流交絡による微小な表面凹凸構造やエンボス処理による比較的大きな凹凸構造が付与されていると、シートの内面同士の接触が凹凸構造の大きさや形状によって低減され、内面同士の液の移動をより低下させることができる。シートの凹凸形状としては、楕円、長方形や筋状など内面同士で重なりにくい線的に非対称な形状が形成された形状であることが好ましい。
 また、シートの断面が部分的な凸部であると、含浸液の量が部分的に高まり、該高まった部分で内面シート同士が接するため、シートの他の部分からの液移動が微小ではあるが起こることで、相対的に凸部に比べ他の部分は低くなる。シートを折りたたんだ場合、折りたたまれた内面側においては、内面上部と内面下部では、液の染み出しが少量であっても起こった場合、折りたたみ部付近での内面上部と内面下部では液量の保持量に差が現れる結果、折りたたみ部分内面の第2層の高密度部分による毛管効果により液が吸い上げられ、相対的な液量差を緩和する効果がより高まる。
In the combination of sheets, if a minute surface uneven structure by hydroentanglement or a relatively large uneven structure by embossing is given, contact between the inner surfaces of the sheet is reduced by the size and shape of the uneven structure, and between the inner surfaces The movement of the liquid can be further reduced. The uneven shape of the sheet is preferably a shape in which a linearly asymmetric shape such as an ellipse, a rectangle, or a streak that hardly overlaps between the inner surfaces is formed.
In addition, when the cross section of the sheet is a partial convex portion, the amount of the impregnating liquid is partially increased, and the inner surface sheets are in contact with each other at the increased portion, so the liquid movement from other parts of the sheet is minute. As a result, the other portions are relatively lower than the convex portions. When the sheet is folded, on the folded inner surface side, even if a small amount of liquid oozes out at the upper inner surface and lower inner surface, the liquid volume is maintained at the upper inner surface and lower inner surface near the folding portion. As a result of the difference in the amount, the liquid is sucked up by the capillary effect by the high-density portion of the second layer on the inner surface of the folding portion, and the effect of alleviating the relative liquid amount difference is further enhanced.
 不織布の総坪量は、皮膚を拭き取ったときのよれにくさ及び含浸液を多く含浸でき、安定性の点から、20~150g/mが好ましく、35~80g/mがより好ましい。

 さらに、不織布の第2層の坪量(g/m)と、後記O/W型乳化物の30℃における粘度(mPa・s)との比(第2層の坪量/粘度)は、安定性、洗浄力、洗浄液の含浸性の点から、0.007~0.7が好ましく、0.01~0.15がより好ましい。
The saturated water ratio of the nonwoven fabric is preferably 500 to 1500%, more preferably 750 to 1000%, from the viewpoints of stability, detergency, and impregnating property of the cleaning liquid. The saturated water ratio is determined by a method based on the JIS L 1913 general nonwoven fabric test method (6.9.2 water retention ratio). That is, after immersing a non-woven fabric having a size of 10 cm × 10 cm in a container containing ion-exchanged water for 5 minutes, the non-woven fabric is taken out from the container and held at both ends with tweezers for 30 seconds, and then impregnated with ion-exchanged water. The weight of the nonwoven fabric is measured and the saturated water ratio is calculated.
Furthermore, the ratio (basis weight / viscosity of the second layer) of the basis weight (g / m 2 ) of the second layer of the nonwoven fabric and the viscosity (mPa · s) at 30 ° C. of the O / W type emulsion described later is From the viewpoint of stability, detergency, and impregnating property of the cleaning liquid, 0.007 to 0.7 is preferable, and 0.01 to 0.15 is more preferable.

 なお、第2層の単位体積当たりの液の量は、以下の式から計算される。
Further, the amount of the liquid per unit volume of the second layer feels that the amount of liquid contained in the sheet is large at the time of wiping, so that the skin can be gently wiped, and from the point of improving stability, 1 × 10 6 to 3 × 10 6 g / m 3 is preferable, 1.02 × 10 6 to 2.8 × 10 6 g / m 3 is more preferable, and 1.04 × 10 6 to 2.6 × 10 6 g / m 3 is preferable. 3 is even more preferable.
The amount of liquid per unit volume of the second layer is calculated from the following equation.
 本発明の皮膚洗浄シートは、O/W型乳化物を含浸させた後において、積層時の品質を安定に保つことができるが、シートを折りたたんで保存した場合にも、品質を安定に保つことができる。
 本発明の皮膚洗浄シートは、前述のようにシートの厚み方向中間に密度の高い第1層とその両面側に密度の低い第2層が配されており、シートはいずれかの面同士が向き合うように折りたたまれる(図1)。
 シートは折りたたまれていることで、折りたたまれた内面側と外面側で液含浸液の染み出し(移動)は異なった挙動を示す。シートの外面では、上述したように第1層による効果により液の染み出し(移動)は抑制され、品質が安定に保たれる。一方、内面では、折り畳まれたシート同士が接触し、第2層が自重での変形(厚み方向の潰れ)が多くなると、含浸液の染み出し(移動)が起こりやすくなるが、本発明のシートは密度の高い第1層により不織布は適度な腰を有するため、シート折り畳み部分から撓んだ変形となることで内面での第2層の接触による変形が抑えられる。
The skin cleansing sheet of the present invention can keep the quality at the time of lamination after impregnating the O / W emulsion, but keeps the quality stable even when the sheet is folded and stored. Can do.
In the skin cleansing sheet of the present invention, as described above, the first layer having a high density is arranged in the middle of the thickness direction of the sheet, and the second layer having a low density is arranged on both sides thereof, and the sheets face each other. (FIG. 1).
Since the sheet is folded, the liquid impregnation liquid oozes out (moves) on the inner surface side and the outer surface side that are folded, and thus the behavior is different. On the outer surface of the sheet, as described above, the liquid seepage (movement) is suppressed by the effect of the first layer, and the quality is kept stable. On the other hand, when the folded sheets come into contact with each other on the inner surface and the second layer is deformed by its own weight (smashing in the thickness direction), the impregnating liquid oozes out (moves) easily. Since the non-woven fabric has an appropriate waist due to the high-density first layer, deformation due to the contact of the second layer on the inner surface is suppressed by the deformation being bent from the sheet folded portion.
 したがって、外面側から内面側へまた内面側同士の液の染み出しは第1層により抑制されるため、含浸液の移動はシートの平面方向への移動が主となるが、本発明のシートでは折りたたみ部分が形成され、該折りたたみ部分で液の平面方向の移動が抑制されている。具体的には、第1層より密度の低い第2層は厚み方向への変形が起こりやすくされており、折りたたんだ際の折りたたみ部分の内側における密度が高くなり、第2層の向かい合っている面の密度より大きく、第1層の密度より小さいが、第1層に近い密度を有している。そのため、内面側では第1層による効果と同様に液の移動を抑制することができる。第2層の折りたたみ部分の内側における密度は、0.05~0.28g/cmが好ましく、0.07~0.19g/cmがより好ましく、0.09~0.17g/cmがさらに好ましい。 Therefore, since the first layer suppresses the seepage of the liquid from the outer surface side to the inner surface side and between the inner surface sides, the movement of the impregnating liquid is mainly performed in the plane direction of the sheet. A folding part is formed, and the movement of the liquid in the planar direction is suppressed at the folding part. Specifically, the second layer, which has a lower density than the first layer, is easily deformed in the thickness direction, and the density inside the folded portion when folded is increased, and the surfaces of the second layer facing each other The density is larger than that of the first layer and smaller than the density of the first layer, but close to the first layer. Therefore, on the inner surface side, the movement of the liquid can be suppressed similarly to the effect by the first layer. Density inside the folded portion of the second layer is preferably 0.05 ~ 0.28g / cm 3, more preferably 0.07 ~ 0.19g / cm 3, is 0.09 ~ 0.17g / cm 3 Further preferred.
 一方、外面においては、密度の高い第1層の影響により折りたたみ部分は鋭角な変形とはならず、外側に撓んだ形状での変形となるため、第2層は鋭角的な変形の場合より第2層が引っ張られて部分的に繊維が少なくされ、疎な構造がより疎となり、厚みも減少する。これにより、外面における含浸液の平面的な移動が抑制される。第2層の折りたたみ部分の外側における密度は、0.005~0.26g/cmが好ましく、0.01~0.17g/cmがより好ましく、0.02~0.15g/cmがさらに好ましい。 On the other hand, on the outer surface, the folded portion is not deformed at an acute angle due to the influence of the dense first layer, but is deformed in a shape bent outward, so that the second layer is more deformed than the acute deformation. The second layer is pulled to partially reduce the fibers, making the sparse structure more sparse and reducing the thickness. Thereby, planar movement of the impregnating liquid on the outer surface is suppressed. The density outside the folded portion of the second layer is preferably 0.005 to 0.26 g / cm 3 , more preferably 0.01 to 0.17 g / cm 3 , and 0.02 to 0.15 g / cm 3. Further preferred.
 前述したように、折りたたみ部分の内面では第2層の密度が高められており、繊維の積層構造の点から、第2層から第1層への染み出しより第2層の平面方向の移動がおこりやすく、折りたたみ内面上部と折りたたみ内面下部において含浸液の保持量に相対的な差が生じると、該構造による毛管効果で液が内面下部から内面上部へと移動しやすい。そのため、折りたたんだ際の折りたたみ部分の内側における密度と第2層の向かい合っている面の密度との比(折りたたみ部分の内側の密度/向かい合っている面の密度)が、1より大きく、1.01以上が好ましく、1.03以上がより好ましく、1.05以上がさらに好ましく、3.5以下が好ましく、2.0以下がより好ましく、1.8以下がさらに好ましく、1.5以下がよりさらに好ましい。
 上述した実施形態に関し、本発明は、更に以下の組成物を開示する。
As described above, the density of the second layer is increased on the inner surface of the folding portion, and the movement of the second layer in the planar direction is caused by the seepage from the second layer to the first layer in terms of the laminated structure of the fibers. If the relative amount of the impregnating liquid retained between the upper part of the folding inner surface and the lower part of the folding inner surface is likely to occur, the liquid tends to move from the lower part of the inner surface to the upper part of the inner surface due to the capillary effect of the structure. Therefore, the ratio between the density inside the folded portion when folded and the density of the facing surface of the second layer (the density inside the folded portion / the density of the facing surface) is greater than 1, 1.01 The above is preferable, 1.03 or more is more preferable, 1.05 or more is further preferable, 3.5 or less is preferable, 2.0 or less is more preferable, 1.8 or less is further preferable, and 1.5 or less is further more preferable. preferable.
