Description
本発明は、含浸させた美容薬液の蒸発を抑え、長時間潤い効果を保持させることが可能な美容シート用不織布及びこれを用いた美容シートに関するものである。 TECHNICAL FIELD The present invention relates to a non-woven fabric for a beauty sheet that can suppress evaporation of an impregnated cosmetic liquid and retain a moisturizing effect for a long time, and a beauty sheet using the same.
顔など身体の美容パックを行う美容シートにおいて、不織布や紙などのシート状基材に溶液、ペーストまたはゼリー状の美容薬液を含浸する美容シートが一般的である。 2. Description of the Related Art In a beauty sheet for performing a body beauty pack such as a face, a beauty sheet in which a sheet-like base material such as a nonwoven fabric or paper is impregnated with a solution, paste or jelly-like cosmetic liquid is common.
従来は、親水性繊維のみで構成される不織布からなる基材に美容薬液を含浸させた美容シートが一般的であった。 Conventionally, a cosmetic sheet in which a base material made of a nonwoven fabric composed only of hydrophilic fibers is impregnated with a cosmetic liquid is common.
また、薬液の蒸散を抑えるためにフィルムを貼り合わせる場合、接着剤やヒートシール接着でフィルム層と親水性繊維層を結合する方法が一般的である。例えば、特開２００３−１３５１４６号公報（特許文献１）では、不織布など基材にフィルムを接合したフェイスマスクが提案されている。 Moreover, when bonding a film in order to suppress the evaporation of a chemical | medical solution, the method of couple | bonding a film layer and a hydrophilic fiber layer with an adhesive agent or heat seal adhesion | attachment is common. For example, Japanese Unexamined Patent Application Publication No. 2003-135146 (Patent Document 1) proposes a face mask in which a film is bonded to a base material such as a nonwoven fabric.
また、ムレなど使用上の問題点について、特開２０００−２８７７５１号公報（特許文献２）では、通気性を有するネット状または多数の穴の開いたフィルムを不織布に接合したフェイスマスクが提案されている。 Further, regarding use problems such as swelling, Japanese Laid-Open Patent Publication No. 2000-287751 (Patent Document 2) proposes a face mask in which a breathable net shape or a film having a large number of holes is bonded to a nonwoven fabric. Yes.
従来のコットンなどの親水性繊維のみで構成される不織布に美容薬液を含浸させた美容シートでは、パックしている最中に有効成分を含む美容薬液の蒸散、または美容薬液中の水分が蒸発し、有効成分が基材中に閉じ込められてしまう。そのため、パック効果が減少するという欠点があった。 In a cosmetic sheet in which a cosmetic liquid is impregnated into a non-woven fabric composed only of hydrophilic fibers such as cotton, the transpiration of the cosmetic liquid containing active ingredients or the moisture in the cosmetic liquid evaporates while being packed. The active ingredient is trapped in the base material. Therefore, there is a drawback that the pack effect is reduced.
不織布など基材にフィルムを接合したフェイスマスクでは、フィルムが薬液蒸散防止層（バリア層）として機能を果たしているが、長時間の使用ではムレを生じ易くなり使い心地が悪くなり易いという欠点があった。 In a face mask in which a film is bonded to a substrate such as a non-woven fabric, the film functions as a chemical vaporization prevention layer (barrier layer). It was.
また、フィルムを美容薬液の蒸散防止層として用いた場合、シートの風合いが硬くなり、身体への装着感や使い心地が悪くなる欠点があった。 Further, when the film is used as an anti-transpiration layer for the cosmetic liquid, there is a disadvantage that the texture of the sheet becomes hard and the feeling of wearing on the body and the feeling of use become worse.
さらに、接着剤やヒートシール接着でフィルム層と親水性繊維層を結合する方法では、結合時、接着剤や熱融着樹脂などにより親水性繊維層が減少したり、加工時の熱で繊維層の密度が高くなってしまい保水機能が阻害される。さらに、端部を貼り合わせ接着した場合や、好ましい形状に切断した場合、フィルムが硬い場合は、端部がエッジ状となってしまい肌にあたり刺激を与え使い心地が悪くなる欠点があった。 Furthermore, in the method of bonding the film layer and the hydrophilic fiber layer by adhesive or heat seal bonding, the hydrophilic fiber layer is reduced by the adhesive or heat-sealing resin during bonding, or the fiber layer is heated by the heat during processing. The density of the water becomes higher and the water retention function is hindered. Furthermore, when the end portions are bonded and bonded, or when the film is hard, the end portions have an edge shape, and the skin is irritated and uncomfortable to use.
ネット状または多数の穴の開いたフィルムを不織布に接合したフェイスマスクでは、通気性を有するものと組み合わせることによってムレの改善を試みているが、美容薬液の蒸散、または美容薬液中の水分が蒸発し、パック効果が減少するという欠点があった。 Face masks made by joining a net-like or multi-perforated film to a non-woven fabric have been tried to improve dripping by combining with a breathable one, but transpiration of cosmetic liquid or evaporation of water in cosmetic liquid has evaporated. However, there is a drawback that the pack effect is reduced.
本発明の美容シート用不織布は、上記の課題を鑑みてなされたものであり、柔らかくしなやかな風合いと良好な装着感を維持し、ムレを生じにくく、さらに美容薬液の蒸散、または美容薬液中の水分の蒸発を抑えて、パック効果を長く保つことができる美容シート用不織布及び前記不織布に美容薬液を含浸させた美容シートを提供することを目的とする。 The nonwoven fabric for beauty sheets of the present invention is made in view of the above-mentioned problems, maintains a soft and supple texture and a good wearing feeling, is less likely to cause stuffiness, and further transpiration of the cosmetic liquid, or in the cosmetic liquid An object of the present invention is to provide a non-woven fabric for a beauty sheet that can suppress the evaporation of moisture and keep the pack effect for a long time, and a beauty sheet in which the non-woven fabric is impregnated with a cosmetic liquid.
本発明の美容シート用不織布は、繊度が０．０１〜１．１デシテックスの極細繊維を５０％（mass）以上含む極細合成繊維層と、親水性繊維層の少なくとも二層を積層した積層不織布であり、前記積層不織布のうち親水性繊維層を身体に接触させて使用し得る事を特徴とするものである。 The nonwoven fabric for beauty sheets of the present invention is a laminated nonwoven fabric obtained by laminating at least two layers of an ultrafine synthetic fiber layer containing 50% (mass) or more of ultrafine fibers having a fineness of 0.01 to 1.1 dtex and a hydrophilic fiber layer. In the laminated nonwoven fabric, the hydrophilic fiber layer can be used in contact with the body.
また、本発明の美容シートは、前記美容シート用不織布に美容薬液を含浸させてなることを特徴とする。 Moreover, the cosmetic sheet of the present invention is characterized in that the cosmetic sheet non-woven fabric is impregnated with a cosmetic liquid.
本発明の美容シート用不織布及び美容シートは、柔らかくしなやかな風合いと良好な装着感を維持したまま、美容薬液並びに美容薬液中の水分の蒸散、蒸発を抑え有効成分の効果を持続するだけでなく、長時間の使用によるムレを抑えることができる。 The non-woven fabric for beauty sheets and the beauty sheet of the present invention not only maintain the effect of active ingredients while suppressing the transpiration and evaporation of moisture in cosmetic liquids and cosmetic liquids while maintaining a soft and supple texture and good wearing feeling. Can suppress stuffiness due to prolonged use.
本発明において、親水性繊維層は主として美容薬液の含浸と保持する機能を有し、極細合成繊維層は主として美容薬液並びに美容薬液中の水分の蒸散、蒸発を抑えつつ、通気性のあるバリア層の機能を有している。 In the present invention, the hydrophilic fiber layer mainly has a function of impregnating and retaining the cosmetic liquid, and the ultrafine synthetic fiber layer is a breathable barrier layer mainly suppressing the evaporation and evaporation of moisture in the cosmetic liquid and the cosmetic liquid. It has the function of
前記親水性繊維層は、親水性繊維のみで構成されていてもよく、他の繊維、例えば疎水性繊維を一部含んでいてもよい。親水性繊維層に疎水性繊維を含む場合、親水性繊維の割合は５０％（mass）以上である事が好ましく、６０％（mass）以上である事がより好ましく、７０％（mass）以上である事がさらに好ましい。 The hydrophilic fiber layer may be composed of only hydrophilic fibers, or may partially include other fibers such as hydrophobic fibers. When the hydrophilic fiber layer includes hydrophobic fibers, the ratio of the hydrophilic fibers is preferably 50% (mass) or more, more preferably 60% (mass) or more, and 70% (mass) or more. Some are more preferable.
前記親水性繊維層を構成する親水性繊維とは、コットン、パルプ、麻などの天然セルロース繊維、ビスコースレーヨン、銅アンモニアレーヨンであるキュプラなどの再生セルロース繊維、溶剤紡糸されたレンチング社製リヨセルやアコーディス社製テンセルなどの精製セルロース繊維、キチン、キトサン成分を含む繊維、絹繊維などを挙げる事が出来る。 The hydrophilic fibers constituting the hydrophilic fiber layer include natural cellulose fibers such as cotton, pulp and hemp, regenerated cellulose fibers such as viscose rayon and cupra, which are copper ammonia rayon, solvent-spun Lyocell manufactured by Lenzing Co., Ltd. Examples include purified cellulose fibers such as Tencor made by Accord, fibers containing chitin and chitosan components, and silk fibers.
また、前記疎水性繊維とは、水に対する接触角が９０゜以上の繊維の事で、ポリオレフィン系、ポリエステル系、ポリアミド系樹脂からなる合成繊維やシリコン成分やフッ素成分を含有する仕上げ油剤で撥水処理を施した繊維などが該当する。 The hydrophobic fiber is a fiber having a contact angle with water of 90 ° or more, and is a synthetic fiber made of polyolefin, polyester, or polyamide resin, and a finishing oil containing a silicon component or a fluorine component. This applies to treated fibers.
前記極細合成繊維層は、０．０１〜１．１デシテックスの極細繊維を５０％（mass）以上含む必要がある。より好ましくは６０％（mass）以上含み、７０％（mass）以上含む事がさらに好ましい。前記極細合成繊維層は、合成繊維のみで構成されている事が好ましいが、親水性繊維を一部含んでいてもよい。極細繊維の割合が５０％（mass）未満であると、美容薬液並びに美容薬液中の水分の蒸散、蒸発を抑えることが出来ず、パック効果が減少してしまうからである。 The ultrafine synthetic fiber layer needs to contain at least 50% (mass) of ultrafine fibers of 0.01 to 1.1 dtex. More preferably, 60% (mass) or more is included, and 70% (mass) or more is further included. The ultrafine synthetic fiber layer is preferably composed of only synthetic fibers, but may contain some hydrophilic fibers. This is because if the proportion of the ultrafine fibers is less than 50% (mass), the transpiration and evaporation of moisture in the cosmetic liquid and the cosmetic liquid cannot be suppressed, and the pack effect is reduced.
例えば、極細合成繊維層がスパンボンド繊維とメルトブロー繊維の混合紡糸法による不織布の場合では、スパンボンド繊維もしくはメルトブロー繊維の繊度が０．０１〜１．１デシテックスの範囲を満たし、さらに５０％（mass）以上含んでいれば、極細合成繊維層となる。 For example, when the ultrafine synthetic fiber layer is a non-woven fabric obtained by a mixed spinning method of spunbond fibers and meltblown fibers, the fineness of the spunbond fibers or meltblown fibers satisfies the range of 0.01 to 1.1 dtex, and is further 50% (mass ) If included, it becomes an ultrafine synthetic fiber layer.
極細合成繊維層を構成する極細繊維の繊度は、１．１デシテックス以下であり、繊度が０．８デシテックス以下である事がより好ましく、繊度が０．６デシテックス以下である事がさらに好ましい。前記極細繊維の繊度が１．１デシテックス以下であれば、空隙孔径が均一で微細となり、蒸発、蒸散を抑え易くなるためである。また、前記極細繊維の繊度は、０．０１デシテックス以上である。繊度０．０１デシテックス以下の繊維は、製造上困難であり、経済的ではないためである。 The fineness of the ultrafine fibers constituting the ultrafine synthetic fiber layer is 1.1 dtex or less, the fineness is more preferably 0.8 dtex or less, and the fineness is more preferably 0.6 dtex or less. This is because if the fineness of the ultrafine fiber is 1.1 dtex or less, the pore diameter is uniform and fine, and it is easy to suppress evaporation and transpiration. The fineness of the ultrafine fiber is 0.01 dtex or more. This is because fibers having a fineness of 0.01 dtex or less are difficult to manufacture and are not economical.
また、極細合成繊維層は、平均繊度が１．７デシテックス以下である事が好ましく、平均繊度が１．１デシテックス以下である事がより好ましく、平均繊度が０．６デシテックス以下である事がさらに好ましい。極細合成繊維層を構成する繊維の平均繊度が１．７デシテックス以下であれば、空隙孔径が均一で微細となり、蒸発、蒸散を抑え易くなるためである。また、極細合成繊維層を構成する繊維の平均繊度は、０．０１デシテックス以上である事が好ましい。繊度０．０１デシテックス以下の繊維は、製造上困難であり、経済的ではないためである。 In addition, the ultrafine synthetic fiber layer preferably has an average fineness of 1.7 dtex or less, more preferably an average fineness of 1.1 dtex or less, and an average fineness of 0.6 dtex or less. preferable. This is because if the average fineness of the fibers constituting the ultrafine synthetic fiber layer is 1.7 dtex or less, the pore diameter is uniform and fine, and it is easy to suppress evaporation and transpiration. Moreover, it is preferable that the average fineness of the fiber which comprises an ultrafine synthetic fiber layer is 0.01 dtex or more. This is because fibers having a fineness of 0.01 dtex or less are difficult to manufacture and are not economical.
前記極細合成繊維層を構成する繊維としては、ポリプロピレン、ポリエチレンなどのオレフィン系繊維、ポリエチレンテレフタレート、ポリブチレンテレフタレートなどのポリエステル系繊維、６−ナイロン、１２−ナイロンなどのポリアミド系繊維、アクリル系繊維などを挙げる事が出来、極細合成繊維層を構成する繊維は美容薬液を遮断しやすい前記疎水性繊維であることが好ましい。 Examples of fibers constituting the ultrafine synthetic fiber layer include olefin fibers such as polypropylene and polyethylene, polyester fibers such as polyethylene terephthalate and polybutylene terephthalate, polyamide fibers such as 6-nylon and 12-nylon, and acrylic fibers. The fibers constituting the ultrafine synthetic fiber layer are preferably the above-mentioned hydrophobic fibers that easily block the cosmetic liquid.
前記極細繊維には、メルトブロー繊維、スパンボンド繊維、海島型繊維を溶出することや分割型繊維を剥離分割することにより得られる繊維などが挙げられる。本発明における極細合成繊維層では、前記極細繊維のうち、メルトブロー繊維、スパンボンド繊維、分割型繊維を剥離分割することにより得られる繊維が製造工程上、また経済的に好ましい。 Examples of the ultrafine fibers include fibers obtained by eluting meltblown fibers, spunbond fibers, sea-island fibers, and separating and dividing split fibers. In the ultrafine synthetic fiber layer in the present invention, among the ultrafine fibers, fibers obtained by peeling and dividing melt blown fibers, spunbond fibers, and split fibers are preferable in terms of the production process.
また、本発明に用いられる積層不織布は、前記親水性繊維層、前記極細合成繊維層以外に他の繊維層を積層してもよい。他の繊維層とは、極細合成繊維層と親水性繊維層以外の繊維層の事であり、合成繊維のみで構成されていてもよいし、合成繊維以外に親水性繊維を含んでいてもよい。 Moreover, the laminated nonwoven fabric used for this invention may laminate | stack other fiber layers other than the said hydrophilic fiber layer and the said ultrafine synthetic fiber layer. The other fiber layer is a fiber layer other than the ultrafine synthetic fiber layer and the hydrophilic fiber layer, and may be composed of only synthetic fibers, or may contain hydrophilic fibers in addition to the synthetic fibers. .
本発明の美容シート用不織布では、種類の異なる極細繊維からなる極細合成繊維層同士の積層であってもよい。例えば、スパンボンド繊維層／メルトブロー繊維層からなる二層の積層不織布の場合、メルトブロー繊維の繊度が０．０１〜１．１デシテックスの範囲であれば、極細合成繊維層はメルトブロー繊維層であり、スパンボンド繊維層の繊度は問題ではない。 In the nonwoven fabric for beauty sheets of this invention, lamination | stacking of the ultrafine synthetic fiber layers which consist of a different kind of ultrafine fiber may be sufficient. For example, in the case of a two-layer laminated nonwoven fabric composed of a spunbond fiber layer / meltblown fiber layer, if the fineness of the meltblown fiber is in the range of 0.01 to 1.1 dtex, the ultrafine synthetic fiber layer is a meltblown fiber layer, The fineness of the spunbond fiber layer is not a problem.
さらに、図面でもって詳しく説明する。図１、図２は、本発明の美容シートに用いられる積層不織布の断面略図を示している。本発明の美容シート用不織布は、極細合成繊維層と親水性繊維層を含む積層不織布であり、図１は極細合成繊維層（１）と親水性繊維層（２）のみで構成されている例である。図２は、美容シート用不織布が４層の積層不織布で構成されている断面略図を示す。例えば繊度１．１デシテックスより太いスパンボンド繊維層、繊度０．０１〜１．１デシテックスのメルトブロー繊維層、繊度１．１デシテックスより太いスパンボンド繊維層と親水性繊維層が積層された不織布で、他の繊維層（３ｂ）、極細合成繊維層（１）、他の繊維層（３ａ）、親水性繊維層（２）の４層の積層不織布からなっている例を示している。 Furthermore, it demonstrates in detail with drawing. 1 and 2 show schematic cross-sectional views of a laminated nonwoven fabric used in the cosmetic sheet of the present invention. The nonwoven fabric for beauty sheets of the present invention is a laminated nonwoven fabric including an ultrafine synthetic fiber layer and a hydrophilic fiber layer, and FIG. 1 is an example composed of only an ultrafine synthetic fiber layer (1) and a hydrophilic fiber layer (2). It is. FIG. 2 shows a schematic cross-sectional view in which the beauty sheet non-woven fabric is composed of a four-layer laminated non-woven fabric. For example, a spunbond fiber layer thicker than a fineness of 1.1 dtex, a melt blown fiber layer having a fineness of 0.01 to 1.1 dtex, a nonwoven fabric in which a spunbond fiber layer thicker than a fineness of 1.1 dtex and a hydrophilic fiber layer are laminated, The example which consists of a laminated nonwoven fabric of 4 layers of another fiber layer (3b), an ultrafine synthetic fiber layer (1), another fiber layer (3a), and a hydrophilic fiber layer (2) is shown.
本発明の美容シート用不織布は、美容薬液を含浸させ親水性繊維層を身体に接触させて使用することが出来る。親水性繊維層を身体に接触させる面（以下、身体接触面という）とした場合、身体接触面から親水性繊維層、極細合成繊維層の順で配置することが出来る。その時必要に応じて、極細合成繊維層の内または外に親水性繊維層または他の繊維層を配置出来る。特に、美容薬液の蒸発、蒸散を抑えるには、極細合成繊維層を最外層、すなわち身体非接触面に配置することが好ましい。 The nonwoven fabric for a beauty sheet of the present invention can be used by impregnating a cosmetic liquid and bringing a hydrophilic fiber layer into contact with the body. When the hydrophilic fiber layer is used as a surface in contact with the body (hereinafter referred to as a body contact surface), the hydrophilic fiber layer and the ultrafine synthetic fiber layer can be arranged in this order from the body contact surface. At that time, if necessary, a hydrophilic fiber layer or another fiber layer can be arranged inside or outside the ultrafine synthetic fiber layer. In particular, in order to suppress the evaporation and transpiration of the cosmetic liquid, it is preferable to arrange the ultrafine synthetic fiber layer on the outermost layer, that is, the non-body contact surface.
また、極細合成繊維層を身体非接触面（最外層）とした場合は、美容薬液の含浸時や美容シートとしての使用時に極細繊維が破損してしまう可能性があるため、破損しやすい極細合成繊維層を保護する目的で、極細合成繊維層の外側に保護繊維層を設けてもよい。保護繊維層は、他の繊維層からなり、合成繊維からなる他の繊維層がより好ましい。例えば、図２の図面では、身体接触面から順に親水性繊維層（２）、他の繊維層（３ａ）、極細合成繊維層（１）、保護繊維層（３ｂ）の順で配置していることを示している。保護繊維層に用いられる繊維層としては、摩耗性に優れたスパンボンド不織布、エアスルー不織布、ポイントボンド不織布などが好ましい。 In addition, if the ultrafine synthetic fiber layer is a non-body contact surface (outermost layer), the ultrafine fiber may be damaged when impregnated with cosmetic liquids or when used as a cosmetic sheet. For the purpose of protecting the fiber layer, a protective fiber layer may be provided outside the ultrafine synthetic fiber layer. A protective fiber layer consists of another fiber layer, and the other fiber layer which consists of synthetic fibers is more preferable. For example, in the drawing of FIG. 2, the hydrophilic fiber layer (2), the other fiber layer (3a), the ultrafine synthetic fiber layer (1), and the protective fiber layer (3b) are arranged in this order from the body contact surface. It is shown that. As the fiber layer used for the protective fiber layer, a spunbond nonwoven fabric, an air-through nonwoven fabric, a point bond nonwoven fabric and the like excellent in abrasion are preferable.
前記親水性繊維層、前記極細合成繊維層と必要に応じて積層される他の繊維層には、それぞれカードウェブ状やエアレイドでの繊維層や湿式抄紙またはエアスルー、ポイントボンド、ニードルパンチ、水流交絡、スパンボンド、メルトブローなどの乾式不織布を使用することが出来る。 The hydrophilic fiber layer, the ultrafine synthetic fiber layer and other fiber layers laminated as necessary include a card web-like or airlaid fiber layer, wet papermaking or air-through, point bond, needle punch, hydroentanglement. Dry-type non-woven fabrics such as spun bond and melt blow can be used.
前記親水性繊維層、前記極細合成繊維層並びに他の繊維層の接合方法では、少なくとも美容薬液を含浸させたり、身体に接触させる処理中に層間の剥離を起こさず、形状を維持出来ればよい。接合法として例えば、溶剤系接着法、溶融樹脂接着法、ヒートエンボス法、超音波法、エアスルー法、ニードルパンチ法、水流交絡法などの技術が利用出来る。 In the method for joining the hydrophilic fiber layer, the ultrafine synthetic fiber layer, and other fiber layers, it is only necessary to maintain the shape without causing peeling between layers during treatment with at least a cosmetic solution or contact with the body. As the bonding method, for example, a solvent-based bonding method, a molten resin bonding method, a heat embossing method, an ultrasonic method, an air-through method, a needle punch method, a hydroentanglement method, or the like can be used.
前記接合方法のうち、水流交絡法やニードルパンチ法は、薬液含浸層の保水性能を十分に発揮出来る点で好ましい。水流交絡法やニードルパンチ法は接合時、親水性繊維層の厚みをコントロールし易いからである。また、水流交絡法やニードルパンチ法では、親水性繊維層と極細合成繊維層をそれぞれ三次元交絡させるだけでなく、一体接合させることが出来る。特に水流交絡法は、シート自体が硬くならず、柔らかくしなやかな風合いを維持する事が出来る点で好ましい。 Among the joining methods, the water entanglement method and the needle punch method are preferable in that the water retention performance of the chemical solution impregnated layer can be sufficiently exhibited. This is because the hydroentanglement method and the needle punch method can easily control the thickness of the hydrophilic fiber layer during bonding. In addition, in the hydroentanglement method and the needle punch method, the hydrophilic fiber layer and the ultrafine synthetic fiber layer can be integrally joined as well as three-dimensionally entangled. In particular, the hydroentanglement method is preferable in that the sheet itself does not become hard and a soft and supple texture can be maintained.
溶剤系接着法、溶融樹脂接着法、ヒートエンボス法、超音波法での接合では、繊維層全面の接合であっても部分的な接合であってもよい。柔らかくしなやかな風合いを維持するためには接合部分の割合が低い部分接合が好ましい。部分接合の割合としては、繊維層間の剥離強度の問題から、全接合面に対して３％以上である事が好ましく、５％以上である事がより好ましい。逆にシート自体が硬くならず、柔らかくしなやかな風合いと良好な装着感とを維持するためには、部分接合の割合は４０％以下である事が好ましく、３０％以下である事がより好ましい。 The bonding by the solvent-based bonding method, the molten resin bonding method, the heat embossing method, and the ultrasonic method may be bonding of the entire fiber layer or partial bonding. In order to maintain a soft and supple texture, partial joining with a low proportion of joining parts is preferable. The ratio of partial bonding is preferably 3% or more, more preferably 5% or more, based on the problem of peel strength between fiber layers, with respect to the entire bonding surface. On the other hand, in order to maintain the soft and supple texture and good wearing feeling without the sheet itself being hard, the proportion of the partial bonding is preferably 40% or less, and more preferably 30% or less.
本発明の美容シート用不織布の目付は、５０ｇ／ｍ2以上であることが好ましく、７０ｇ／ｍ2以上であることがさらに好ましい。５０ｇ／ｍ2に満たない場合、極細合成繊維層が少なくなりすぎて美容薬液の含浸量が低くなりすぎ、美容効果が薄くなってしまったり、強度不足により取り扱いが困難になる恐れがある。また、目付は１５０ｇ／ｍ2以下であることが好ましく、１２０ｇ／ｍ2以下であることがさらに好ましい。１５０ｇ／ｍ2を超えると不織布の嵩が出たり、硬くなったりし、身体への接触時に装着しにくくなるだけでなく、コスト的にも有効ではなくなってしまう。 The basis weight of the nonwoven fabric for a beauty sheet of the present invention is preferably 50 g / m 2 or more, and more preferably 70 g / m 2 or more. If it is less than 50 g / m 2 , the amount of the ultrafine synthetic fiber layer becomes too small, the amount of the cosmetic liquid impregnated becomes too low, the cosmetic effect becomes thin, and the handling may be difficult due to insufficient strength. The basis weight is preferably 150 g / m 2 or less, and more preferably 120 g / m 2 or less. If it exceeds 150 g / m 2 , the nonwoven fabric will be bulky or hard, and it will not only be difficult to wear when in contact with the body, but it will not be cost effective.
また、極細合成繊維層の目付は５ｇ／ｍ2以上であることが好ましく、７ｇ／ｍ2以上であることがさらに好ましい。５ｇ／ｍ2に満たない場合、通気性を維持出来るが、バリア層としての効果を発揮出来ない。目付は５０ｇ／ｍ2以下であることが好ましく、４０ｇ／ｍ2以下であることがさらに好ましい。５０ｇ／ｍ2を超えるとコスト的に有効でなくなるだけでなく、通気性が著しく阻害され、ムレ易くなってしまう。 The basis weight of the ultrafine synthetic fiber layer is preferably 5 g / m 2 or more, and more preferably 7 g / m 2 or more. If it is less than 5 g / m 2 , the air permeability can be maintained, but the effect as a barrier layer cannot be exhibited. The basis weight is preferably 50 g / m 2 or less, and more preferably 40 g / m 2 or less. If it exceeds 50 g / m 2 , not only is it not cost effective, but also the air permeability is significantly impaired, and it becomes easy to sag.

However, it was clearly superior in terms of long-term retention of cosmetic liquids. Moreover, in Example 1, since the spunbond fiber layer is laminated as the protective fiber layer of the meltblown fiber layer which is an ultrafine synthetic fiber layer, even when actually handled, it is not easily damaged and protects the ultrafine fiber layer. The function to perform was fully exhibited, and the air permeability and the barrier property were not hindered.
