本発明は、吸収性物品の表面シートに関し、更に詳しく
は、不織布を基材とし、生理用ナプキンなどの吸収性物
品の肌当面を形成する表面シートに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a surface sheet for absorbent articles, and more specifically, a surface sheet that uses a nonwoven fabric as a base material and forms the skin-contacting surface of absorbent articles such as sanitary napkins. Regarding the top sheet.
従来、生理用ナプキンなどの吸収性物品において、その

うえ、ナプキンの内部に吸収された体液が逆流して容易
に表面シートの表面から滲出する。そのため、肌に湿潤
感、ひいては不快感を与える。Conventionally, in absorbent articles such as sanitary napkins, hydrophobic resin has been partially applied to the surface of a nonwoven fabric as a top sheet for the purpose of spot absorption of body fluids on the skin, reducing residual body fluids, and improving the feeling of trying. It is known that a hydrophobic film with a desired pattern is formed by However, in this case, the hydrophobic coating is located on the surface of the nonwoven fabric on substantially the same plane as the hydrophobic coating, so the coating is not located and the exposed liquid permeable area of the nonwoven fabric is also an impermeable area. It adheres closely to the wearer's skin in the same way as the hydrophobic coating. Therefore, stuffiness tends to occur between the top sheet and the skin, and body fluids absorbed into the napkin easily flow back and ooze out from the surface of the top sheet. Therefore, it gives a feeling of moisture to the skin and even discomfort.
一方、生理用ナプキンなどの吸収性物品において、前記

とがある。On the other hand, it is known that absorbent articles such as sanitary napkins have a hydrophobic resin film with an array of openings and a body fluid introduction tube protruding from the bottom surface for almost the same purpose as the above-mentioned articles. There is. However, in this device, when body pressure is applied during use, the body fluid introduction tube may be deformed or blocked, making it difficult or impossible to introduce body fluid.
本発明の目的は、不透液部としての凸部と透液部として

供することにある。An object of the present invention is to provide a surface sheet for an absorbent article that can eliminate the above-mentioned defects by arranging convex portions as liquid-impermeable portions and recessed portions as liquid-permeable portions in a desired pattern. It is in.
前記目的を達成するための本発明に係る表面シートは、
熱可塑性繊維を含む透液性不織布に凸部を所要パターン
て配列形成し、前記凸部の頂面に熱可塑性かつ疎水性皮
膜層を一体に融着接合する。The top sheet according to the present invention for achieving the above object has the following features:
Convex portions are arranged in a desired pattern on a liquid-permeable nonwoven fabric containing thermoplastic fibers, and a thermoplastic and hydrophobic coating layer is integrally fused and bonded to the top surface of the convex portions.
前記凸部は、互いに連続に形成する場合と、互いに不連
続に形成する場合とかある。The convex portions may be formed continuously or discontinuously.
前記皮膜層の面積比率は１０〜８０％になし、前記皮膜
層の各々の間隔は０．５〜５■ｌになし、その皮膜層を
含む前記凸部の高さは０．５〜３１■になすことか好ま
しい。The area ratio of the film layer is 10-80%, the interval between each film layer is 0.5-5μl, and the height of the convex portion including the film layer is 0.5-31μl. It is preferable to do something.

て、物品の内部に吸収される。(Function) In the top sheet according to the present invention having the above configuration,
When used as a top sheet of an absorbent article, the hydrophobic film layer located on the top surface of the convex portion comes into contact with the skin. At the same time, body fluid in the concave portions between the convex portions flows through the concave portions, and at the same time, body fluid in the film layer flows to the concave portions, permeates through the concave portions, and is absorbed into the interior of the article.
体圧が加わったとき、この部位における表面シートの凸

れると復元する。このように表面シートはクツション性
を有する。もとより、前記透液部は、体圧下で凸部がへ
こみ又はつぶれても、これが体液の透過にいささかも支
障にはならない。When body pressure is applied, the convex portion of the topsheet in this area may be dented or crushed, but it will return to its original state when the body pressure is released. In this way, the topsheet has cushioning properties. Of course, even if the convex portion of the liquid-permeable portion is dented or collapsed under body pressure, this does not impede the permeation of body fluid in the slightest.
図面を参照して、本発明に係る表面シートの実施例を説
明すると、以下のとおりである。Examples of the top sheet according to the present invention will be described below with reference to the drawings.

接合することで、表面シートｌを構成してある。In Figs. Mg1 and 2, a nonwoven fabric 2 containing thermoplastic fibers is embossed under heating to form convex portions 3 in a regular array, and a hydrophobic film layer 4 is integrally formed on the top surface of the convex portions 3. The top sheet 1 is formed by fusion bonding.

にすればよい。The nonwoven fabric 2 may be a melt bonded nonwoven fabric, a spunbond nonwoven fabric, or other nonwoven fabric. It is preferable that the nonwoven fabric 2 contains 10% or more of thermoplastic fibers, in order to maintain its shape by embossing under heating and to increase the strength of the fusion bond to the convex portions 3 of the coating layer 4. The nonwoven fabric 2 is treated with a surfactant or mixed with the constituent fibers to improve the permeability of body fluids, if necessary. The basis weight, apparent thickness, and apparent thickness of the nonwoven fabric 2 are generally 5 to 50 g/■2.0.5 to 1.5■1, respectively.
Just do it.
図示の凸部３は、不連続（独立）パターンに賦与してあ

るたけ避けるようにするうえで好ましい。The illustrated convex portions 3 may preferably be provided in a discontinuous (independent) pattern, or may be provided in an appropriate continuous pattern. Regardless of whether the convex portions 3 are formed in a mutually continuous or mutually discontinuous pattern, the interval I between the convex portions 3 is 0.
5 to 5■, and the height of the convex portion 3 including the film layer 4, that is, the height H between the top surface of the film layer 4 and the bottom surface of the recess 5 is 0.
．． 5 to 3 ■■, and the area ratio of film layer 4 is 10 to 80.
%, while improving the permeation of body fluids in the recesses 5, when the body fluids absorbed by the absorber flow back into the recesses 5 and ooze out, it prevents the repelled body fluids from coming into contact with the skin as much as possible. Preferable to avoid.
皮膜層４の厚さは、凸部３の頂面を被覆することかてき
るとともに、不織布２の柔軟性を阻害しないかぎりは、
特に問わない。The thickness of the film layer 4 is determined as long as it covers the top surface of the convex portion 3 and does not inhibit the flexibility of the nonwoven fabric 2.
There is no particular question.
こうした表面シートｌを得るには、例えば、不織布２を
加熱下にエンボス処理したのちに、不織布２の上面に２
軸延伸処理したポリエチレンなどの熱可塑性樹脂フィル
ムを緊張下に重ね合せ、そのフィルムに熱風を当てる。In order to obtain such a top sheet l, for example, after the nonwoven fabric 2 is embossed under heating, two
Axially stretched thermoplastic resin films such as polyethylene are stacked together under tension, and hot air is applied to the films.
そうすることにより、フィルムの全体を軟化させ、凸部
３の頂面に接触するフィルム部分を融着させるとともに
、凹部５上に位置するフィルム部分を収縮させて凸部３
に引き寄〃せることて、皮膜層４を形成する。By doing so, the entire film is softened, the film portion that contacts the top surface of the convex portion 3 is fused, and the film portion located on the concave portion 5 is contracted to form the convex portion 3.
A film layer 4 is formed.
また、この方法にかえて、凸部３を賦与する一対の表面
凹凸ロールの一方の表面に不織布２を当てた状態て、凸
部３の頂面に樹脂を塗布して皮膜層４を形成することも
てきる。Alternatively, instead of this method, the film layer 4 is formed by applying resin to the top surface of the protrusions 3 while the nonwoven fabric 2 is applied to one surface of a pair of surface unevenness rolls that provide the protrusions 3. It can also happen.
前記構成を有する表面シート１は、例えば、第３図に示
すように、吸収体６の下面及び側面に不透液性シート７
を位置させ、この積層体の全体を表面シートｌ（ただし
、第３図では、凸部３及び凹部３の図示を省略してある
）で包括して生理用ナプキンを構成するのに使用する。For example, as shown in FIG.
is used to construct a sanitary napkin by enclosing the entire laminate with a topsheet 1 (however, the projections 3 and recesses 3 are not shown in FIG. 3).
（発明用の効果）
以上の構成及び作用を有する本発明に係る表面シートに
よれば、互い連続又は不連続する特定の面積比率、間隔
及び高さを有する凸部頂面上の疎水性皮膜層には体液が
ほとんど残留することがなく、そのため肌に与える湿潤
感やべとつき感を最少にすることができる。(Effects for the Invention) According to the top sheet of the present invention having the above configuration and operation, the hydrophobic film layer on the top surface of the convex portions has a specific area ratio, interval, and height that are continuous or discontinuous with each other. Almost no body fluid remains in the product, which minimizes the feeling of moisture and stickiness on the skin.
しかも、凸部間の透液部としての凹部は、凸部の変形で
その透液機能を阻害されることがないから、体液を充分
に透過させることかきる。Moreover, since the liquid permeation function of the recesses between the protrusions is not inhibited by the deformation of the protrusions, body fluids can sufficiently permeate therethrough.
