It was measured at the temperature shown in Table 5 below according to the vibrational density test method. For measurement, DA-505 of Kyoto Electronics Industries Ltd. was used. The results are shown in Table 5.
  • the blood modifying agent has a water solubility of about 0.00 to about 0.05 g per 100 g of water at 25 ° C., but its solubility in water is very low.

The absorbent article 1 has a liquid-permeable top sheet 2 provided on the skin side (skin contact side), a liquid-impermeable back sheet 3 provided on the clothing side (non-skin contact side), and a top sheet 2 and the back sheet 3 are provided with a liquid-retaining absorbent body 4 and a body portion 10 provided with liquid-impermeable side sheets 5 provided on both sides in the width direction of the top sheet 2; It includes a pair of wing portions 6 provided with a side sheet 5 and a back sheet 3 extending in the width direction from both side edges.
 符号61はウイング部6の付け根(本体部10とウイング部6との間の境界)を示す。たとえば、ウイング部6の長手方向両側において、吸収性物品1の幅が急に大きくなる2つの点を結んだ直線がウイング部6の付け根61と見なすことができる。ウイング部6の着衣側の面に粘着部7が設けられている。また、本体部10の着衣側の面にも粘着部7が設けられている。なお、図1において、吸収性物品1の幅方向はX方向であり、長手方向はY方向である。また、吸収性物品1の平面方向は、XY方向である。なお、サイドシート5を設けないで、本体部10のトップシート2を幅方向に延出させて、ウイング部6はトップシート2およびバックシート3を備えるようにしてもよい。 The code | symbol 61 shows the root of the wing part 6 (boundary between the main-body part 10 and the wing part 6). For example, a straight line connecting two points where the width of the absorbent article 1 suddenly increases on both sides in the longitudinal direction of the wing portion 6 can be regarded as the root 61 of the wing portion 6. An adhesive portion 7 is provided on the surface of the wing portion 6 on the clothes side.

 トップシート2は、着用者から排出された尿、経血などの体液を、吸収体4へ移動させる。トップシート2はその全部または一部が液透過性であり、トップシート2の液透過域は、液透過性の不織布、織布、多数の液透過孔が形成された樹脂フィルムまたは多数の網目を有するネット状シートなどで形成され得る。 The top sheet 2 transfers body fluid such as urine and menstrual blood discharged from the wearer to the absorber 4. The top sheet 2 is wholly or partially liquid-permeable, and the liquid-permeable area of the top sheet 2 is a liquid-permeable non-woven fabric, a woven fabric, a resin film having a large number of liquid-permeable holes, or a large number of meshes. It can be formed of a net-like sheet or the like.
 トップシート2は、好ましくは不織布から作製される。トップシート2に用いる不織布の素材としては、天然繊維、化学繊維のいずれも使用することが可能である。天然繊維の例としては、粉砕パルプ、コットンなどのセルロースが挙げられる。化学繊維の例としては、レーヨンおよびフィブリルレーヨンなどの再生セルロース、アセテートおよびトリアセテートなどの半合成セルロース、熱可塑性疎水性化学繊維、ならびに親水化処理を施した熱可塑性疎水性化学繊維が挙げられる。熱可塑性疎水性化学繊維としては、ポリエチレン(PE)、ポリプロピレン(PP)、ポリエチレンテレフタレート(PET)などの単繊維、PEとPPとをグラフト重合してなる繊維および芯鞘構造などの複合繊維が挙げられる。 The top sheet 2 is preferably made of non-woven fabric. As a non-woven material used for the top sheet 2, any of natural fibers and chemical fibers can be used. Examples of natural fibers include cellulose such as ground pulp, cotton and the like. Examples of chemical fibers include regenerated celluloses such as rayon and fibril rayon, semi-synthetic celluloses such as acetate and triacetate, thermoplastic hydrophobic chemical fibers, and thermoplastic hydrophobic chemical fibers subjected to hydrophilization treatment. Examples of thermoplastic hydrophobic chemical fibers include single fibers such as polyethylene (PE), polypropylene (PP) and polyethylene terephthalate (PET), fibers obtained by graft polymerization of PE and PP, and composite fibers such as a core-sheath structure. Be
 トップシート2に用いる不織布を作製するとき、乾式法(カード法、スパンボンド法、メルトブローン法、エアレイド法等)および湿式法のいずれか、また乾式法および湿式法を組み合わせてウェブフォーミングを実施してもよい。トップシート2に用いる不織布を作製するときのウェブのボンディング方法としては、サーマルボンディング、ニードルパンチ、ケミカルボンディングなどの方法が挙げられるが、これらの方法に限定されない。また、水流交絡法によりシート状に形成したスパンレースをトップシート2に用いてもよい。 When producing a non-woven fabric used for the top sheet 2, web forming is carried out by combining either a dry method (card method, spun bond method, meltblown method, air laid method, etc.) and a wet method, or a dry method and a wet method. It is also good. Examples of the method of bonding the web when producing the non-woven fabric used for the top sheet 2 include methods such as thermal bonding, needle punch, chemical bonding and the like, but are not limited to these methods. In addition, a spunlace formed in a sheet shape by a water flow entanglement method may be used for the top sheet 2.
 トップシート2に用いる不織布の繊維には、芯成分の融点が鞘成分より高い芯鞘タイプ、芯鞘の偏芯タイプ、または左右成分の融点が異なるサイドバイサイドタイプの複合繊維を使用してもよい。また、中空タイプの繊維や、扁平、Y型およびC型などの異型繊維や、潜在捲縮もしくは顕在捲縮の立体捲縮繊維や、水流、熱またはエンボス加工などの物理的負荷により分割する分割繊維などの繊維がトップシート2に用いる不織布に混合されていてもよい。 As fibers of non-woven fabric used for the top sheet 2, composite fibers of core-sheath type, core-sheath eccentric type, or side-by-side type of different melting points of left and right components may be used. In addition, hollow fibers, irregular fibers such as flat, Y-type and C-type, three-dimensional crimped fibers with latent crimp or apparent crimp, and split by physical load such as water flow, heat or embossing Fibers such as fibers may be mixed in the non-woven fabric used for the top sheet 2.
 液体の入り込みや肌触りを考慮すると、トップシート2に用いる不織布の繊維の繊度は、好ましくは1.1~8.8dtexである。 In consideration of the penetration of the liquid and the touch, the fineness of the non-woven fabric used for the top sheet 2 is preferably 1.1 to 8.8 dtex.
 トップシート2に疎水性合成繊維を使用する場合、トップシート2の液体の入り込み性やリウェットバックを考慮して、親水剤や撥水剤などを疎水性合成繊維に練りこんだり、親水剤や撥水剤などで疎水性合成繊維をコーティングしたりしてもよい。また、コロナ処理やプラズマ処理によって疎水性合成繊維に親水性を付与してもよい。これにより、後述の血液改質剤が親油性の場合、血液改質剤塗布領域18に親水性の箇所と親油性の箇所とがまばらに共存することになり、体液(たとえば経血)の親水性成分(主に血しょう)および親油性成分(主に血球)の両方がトップシート2から吸収体4へ速やかに移行する。 When hydrophobic synthetic fibers are used for the top sheet 2, in consideration of the liquid penetration and rewet of the top sheet 2, the hydrophilic agent, the water repellant, etc. are kneaded into the hydrophobic synthetic fibers, the hydrophilic agent or the water repellent The hydrophobic synthetic fiber may be coated with a solution or the like. In addition, the hydrophobic synthetic fiber may be rendered hydrophilic by corona treatment or plasma treatment. Thereby, when the blood modifying agent described later is lipophilic, the hydrophilic portion and the lipophilic portion coexist in the blood modifying agent application region 18 sparsely, and the hydrophilicity of the body fluid (for example, menstrual blood) Both the sex component (mainly plasma) and the lipophilic component (mainly blood cells) are rapidly transferred from the top sheet 2 to the absorber 4.
 トップシート2の隠ぺい性を高めるために、トップシート2に用いる不織布の繊維に酸化チタン、硫酸バリウムおよび炭酸カルシウムなどの無機フィラーを含有させてもよい。不織布の繊維が芯鞘タイプの複合繊維である場合、芯のみに無機フィラーを含有させてもよいし、鞘のみに含有させてもよい。 In order to enhance the hiding property of the top sheet 2, the non-woven fabric used for the top sheet 2 may contain an inorganic filler such as titanium oxide, barium sulfate and calcium carbonate. When the non-woven fiber is a core-sheath type composite fiber, only the core may contain the inorganic filler, or only the sheath may contain it.
 トップシート2の少なくとも***口当接域16には、後述の血液改質剤が塗布された血液改質剤塗布領域18が設けられている。ここで、***口当接域16とは、着用者の体液の***口に当接する位置を中心とした長手方向の長さが、好ましくは50~200mmであり、より好ましくは70~150mmであり、幅方向の長さが、好ましくは10~80mmであり、より好ましくは20~50mmである。吸収性物品1を包装するために、一対のウイング部6の幅方向外側の縁62がお互いに接するように一対のウイング部6を幅方向内側に折り畳むと、血液改質剤塗布領域18の大部分またはすべての部分が折り畳んだウイング部6によって覆い隠される(図5および図7参照)。 At least the discharge port contact area 16 of the top sheet 2 is provided with a blood modifier application area 18 to which a blood modifier described later is applied. Here, with the excretory opening contact area 16, the length in the longitudinal direction centering on the position where it abuts on the excretory opening of the wearer's body fluid is preferably 50 to 200 mm, more preferably 70 to 150 mm. The length in the width direction is preferably 10 to 80 mm, more preferably 20 to 50 mm. When the pair of wings 6 is folded inward in the width direction so that the edges 62 in the width direction of the pair of wings 6 contact each other in order to wrap the absorbent article 1, the size of the blood modifier application region 18 is large. Parts or all parts are obscured by the folded wings 6 (see FIGS. 5 and 7).
 トップシート2は、少なくとも***口当接域16に、長手方向(Y方向)に延在し、長手方向(Y方向)に交差する方向、たとえば幅方向(X方向)に並ぶ突部21および凹部22を有する。図3を参照して、トップシート2に設けられた突部21および凹部22を詳細に説明する。図3は、トップシート2の突部21および凹部22を拡大した斜視図である。なお、突部21および凹部22が延びる方向は、所定の方向であれば、長手方向に限定されない。 The top sheet 2 extends in the longitudinal direction (Y direction) at least in the discharge port contact area 16, and the projection 21 and the recess are arranged in a direction intersecting the longitudinal direction (Y direction), for example, in the width direction (X direction) Having 22. With reference to FIG. 3, the protrusion 21 and the recessed part 22 provided in the top sheet 2 are demonstrated in detail. FIG. 3 is an enlarged perspective view of the protrusion 21 and the recess 22 of the top sheet 2. The direction in which the protrusion 21 and the recess 22 extend is not limited to the longitudinal direction as long as it is a predetermined direction.
 図3に示すように、トップシート2は、長手方向(Y方向)に延在しており、長手方向(Y方向)に交差する方向、たとえば幅方向(X方向)に並ぶ複数の突部21および凹部22を含む。突部21の断面の形状は、たとえば、略U字形状である。略U字形状には、U字形状の他に、角を丸めたり、直線を曲線に変えたりするなどの変形を加えるとU字形状になる形状も含まれる。たとえば、略U字形状には、V字形状、M字形状および台形も含まれる。また、突部21の断面の形状をΩ形状にしてもよい。 As shown in FIG. 3, the top sheet 2 extends in the longitudinal direction (Y direction), and a plurality of protrusions 21 aligned in a direction intersecting the longitudinal direction (Y direction), for example, in the width direction (X direction) And the recess 22. The shape of the cross section of the protrusion 21 is, for example, a substantially U shape. The substantially U-shape includes, in addition to the U-shape, a shape that becomes a U-shape when it is deformed such as rounding corners or changing a straight line into a curve. For example, the substantially U-shape also includes V-shape, M-shape and trapezoid. Further, the shape of the cross section of the protrusion 21 may be Ω.
 突部21のもっとも厚くなっている部分の厚さは、好ましくは0.3~15mmであり、より好ましくは0.5~5mmである。また、突部の幅方向(X方向)の長さは、好ましくは0.5~30mmであり、より好ましくは1.0~10mmである。隣接する突部の幅方向(X方向)の頂点間の距離(ピッチ)は、好ましくは0.5~30mmであり、より好ましくは3~10mmである。凹部22のもっとも薄くなっている部分の厚さは、突部21のもっとも厚くなっている部分の厚さに対して好ましくは1~50%であり、より好ましくは5~20%である。凹部22の幅方向(X方向)の長さは、好ましくは0.1~30mmであり、より好ましくは0.5~10mmである。 The thickness of the thickest portion of the projection 21 is preferably 0.3 to 15 mm, more preferably 0.5 to 5 mm. The length in the width direction (X direction) of the projection is preferably 0.5 to 30 mm, more preferably 1.0 to 10 mm. The distance (pitch) between the apexes in the width direction (X direction) of the adjacent protrusions is preferably 0.5 to 30 mm, more preferably 3 to 10 mm. The thickness of the thinnest portion of the recess 22 is preferably 1 to 50%, more preferably 5 to 20% of the thickness of the thickest portion of the protrusion 21. The length in the width direction (X direction) of the recess 22 is preferably 0.1 to 30 mm, more preferably 0.5 to 10 mm.
 突部21の中央部23の繊維密度は、好ましくは、突部21の側部24および/または凹部22の繊維密度よりも低い。たとえば、突部21の中央部23および凹部22の繊維密度は0.005~0.20g/cm3であり、好ましくは0.007~0.07g/cm3である。トップシートのそれぞれの場所の繊維密度は、たとえば、以下のようにして測定できる。突部21および凹部22を形成した所定の機械方向(MD)の長さのトップシートをサンプリングする。そして、マイクロスコープなどを使用してトップシートの幅方向(CD)の断面の顕微鏡写真を撮影し、トップシートにおける突部21の中央部の断面積、突部の側部の断面積および凹部の断面積を、画像処理装置を使用して測定する。次に、液体窒素などを使用してトップシートを冷却し、冷却したトップシートの突部の中央部、突部の側部および凹部をトップシートからそれぞれ切り離す。そして、切り離した突部の中央部、突部の側部および凹部の重量をそれぞれ測定する。最後に、突部の中央部、突部の側部および凹部の測定したそれぞれの重量を、上述の機械方向(MD)長さと断面積とで割り算することによって、トップシートの突部の中央部の繊維密度、突部の側部の繊維密度および凹部の繊維密度を算出できる。また、突部21の中央部23の繊維密度と、突部21の側部24および/または凹部22の繊維密度との間の大小関係は、トップシートの断面の顕微鏡写真の繊維の疎密関係から判断できる。繊維密度の符号25は、トップシート2の繊維を示す。 The fiber density of the central portion 23 of the projection 21 is preferably lower than the fiber density of the side 24 and / or the recess 22 of the projection 21. For example, the fiber density of the central portion 23 of the projection 21 and the recess 22 is 0.005 to 0.20 g / cm 3 , preferably 0.007 to 0.07 g / cm 3 . The fiber density of each place of the top sheet can be measured, for example, as follows. A top sheet having a predetermined machine direction (MD) length, in which the projection 21 and the recess 22 are formed, is sampled. Then, a microscope photograph or the like is used to take a photomicrograph of a cross section in the width direction (CD) of the top sheet, and the cross section of the central portion of the protrusion 21 in the top sheet, the cross section of the side portion of the protrusion, and the recess Cross sectional area is measured using an image processor. Next, the top sheet is cooled using liquid nitrogen or the like, and the central portion, the sides of the projection, and the recess of the cooled top sheet are respectively separated from the top sheet. Then, the weights of the central portion of the separated protrusion, the side portion of the protrusion, and the recess are measured. Finally, by dividing the measured weights of the central part of the projection, the side part of the projection and the recess by the machine direction (MD) length and the cross-sectional area described above, the central part of the projection of the top sheet Fiber density of the side of the protrusion and fiber density of the recess can be calculated. In addition, the magnitude relationship between the fiber density of the central portion 23 of the protrusion 21 and the fiber density of the side portion 24 and / or the recess 22 of the protrusion 21 is from the density relationship of fibers of the cross section of the top sheet. It can be judged. The fiber density code 25 indicates the fibers of the top sheet 2.
 次に、図4を参照して、トップシート2に突部21および凹部22を形成する方法を説明する。図4に示すように、トップシート2の材料となるウェブ120を網状支持部材130の上に配置し、そして機械方向(MD)に移動させる。ウェブ120は吹き出し部140と吸引部150との間を移動する。吹き出し部140は気体141をウェブ120に噴射し、吸引部150は、吹き出し部140から噴射した気体141を吸引する。吹き出し部140から噴射した気体141は、ウェブ120の繊維を掻き分ける。これにより、トップシート2の凹部22に対応する溝122がウェブ120に形成される。また、吹き出し部140から噴射した気体141によって掻き分けられた繊維は、溝122の両脇に集まる。これにより、トップシート2の突部21に対応する突部121が溝122の両側に形成される。 Next, with reference to FIG. 4, a method of forming the protrusion 21 and the recess 22 in the top sheet 2 will be described. As shown in FIG. 4, a web 120 from which the topsheet 2 is made is placed on the mesh support member 130 and moved in the machine direction (MD). The web 120 moves between the blowout unit 140 and the suction unit 150. The blowout unit 140 jets the gas 141 onto the web 120, and the suction unit 150 sucks the gas 141 jetted from the blowout unit 140. The gas 141 jetted from the blowout unit 140 scrapes the fibers of the web 120. Thereby, the groove 122 corresponding to the recess 22 of the top sheet 2 is formed in the web 120. Further, the fibers scraped off by the gas 141 jetted from the blowout portion 140 gather on both sides of the groove 122. Thereby, the protrusions 121 corresponding to the protrusions 21 of the top sheet 2 are formed on both sides of the groove 122.
 網状支持部材130は、通気性を有する網状の支持体である。たとえば、ポリエステル、ポリフェニレンサルファイド、ナイロン、導電性モノフィラメントなどの樹脂性の糸、または、ステンレス、銅、アルミなど金属性の糸などを、平織・綾織・朱子織・二重織・スパイラル織などで織り込まれた通気性ネットを網状支持部材130として使用できる。 The mesh support member 130 is a mesh support having breathability. For example, polyester, polyphenylene sulfide, nylon, resinous threads such as conductive monofilaments, or metallic threads such as stainless steel, copper, aluminum, etc. are woven by plain weave, twill weave, satin weave, double weave, spiral weave, etc. The breathable net can be used as the mesh support member 130.
 吹き出し部140には、幅方向に並んだ複数の吹き出し口(不図示)を含む。これにより、吹き出し部140は、幅方向(CD)に並んだ複数の気体141をウェブ120に噴射できる。また、吹き出し部140から噴射する気体141は、たとえば、常温のまたは加熱された窒素、空気および水蒸気である。吹き出し部140から噴射する気体141は、液体または固体の微粒子を含んでもよい。 The blowout unit 140 includes a plurality of blowout ports (not shown) arranged in the width direction. Thus, the blowout unit 140 can inject the plurality of gases 141 aligned in the width direction (CD) onto the web 120. Moreover, the gas 141 injected from the blowout part 140 is, for example, normal temperature or heated nitrogen, air and water vapor. The gas 141 jetted from the blowoff unit 140 may contain liquid or solid particles.
 吹き出し部140を幅方向(CD)に往復移動させることによって、蛇行状(波状、ジグザグ状)の溝部をウェブに形成できる。また、吹き出し部140から間欠的に気体141をウェブ120に噴射することによって不連続な溝をウェブに形成できる。 By reciprocating the blowout portion 140 in the width direction (CD), it is possible to form a serpentine (wavelike, zigzag) groove portion in the web. In addition, discontinuous grooves can be formed in the web by intermittently injecting the gas 141 onto the web 120 from the blowout portion 140.
 突部121の側面は、掻き分けられた繊維が密集するので、突部121の側面の繊維密度が高くなる。また、溝122は、吹き出し部140から噴出した気体141が当たり、ウェブが圧縮されるので、溝122における繊維密度は高くなる。一方、突部121の中央部では、掻き分けられた繊維が集まるものの、吹き出し部140から噴出した気体141によって圧縮されないので、突部121の中央部の繊維密度は低くなる。これより、突部21の中央部23の繊維密度は、突部21の側部24および/または凹部22の繊維密度よりも低くなる。 Since the scraped fibers are densely packed on the side surface of the protrusion 121, the fiber density of the side surface of the protrusion 121 is increased. Further, since the groove 122 receives the gas 141 ejected from the blowout portion 140 and the web is compressed, the fiber density in the groove 122 becomes high. On the other hand, at the central portion of the protrusion 121, although the scraped fibers gather, they are not compressed by the gas 141 ejected from the blowout portion 140, so the fiber density at the central portion of the protrusion 121 becomes low. Thus, the fiber density of the central portion 23 of the projection 21 is lower than the fiber density of the side portion 24 and / or the recess 22 of the projection 21.
 図1および図2に示すバックシート3は、吸収体4に吸収された体液が外へ漏れ出すのを防止する。バックシート3には、体液を透過しない材料が使用される。たとえば、バックシート3として、疎水性の不織布、ポリエチレンおよびポリプロピレンなどの不透水性のプラスチックフィルムまたは不織布と不透水性プラスチックフィルムとのラミネートシートなどが使用される。また、耐水性の高いメルトブローン不織布を強度の強いスパンボンド不織布で挟んだスパンボンド・メルトブロー・スパンボンド(SMS)繊維不織布をバックシート3として使用してもよい。体液は通さない通気性を有する材料をバックシート3として使用することにより、着用時のムレを低減させることができる。バックシート3はホットメルト接着剤などの接着剤を使用してトップシート2と接合する。 The back sheet 3 shown in FIGS. 1 and 2 prevents the body fluid absorbed by the absorber 4 from leaking out. The back sheet 3 is made of a material that is impermeable to body fluid. For example, as the back sheet 3, a hydrophobic non-woven fabric, an impermeable plastic film such as polyethylene and polypropylene or a laminate sheet of non-woven fabric and an impermeable plastic film, or the like is used. Alternatively, a spunbond-meltblown-spunbond (SMS) fibrous nonwoven fabric may be used as the back sheet 3 in which a highly water-resistant meltblown nonwoven fabric is sandwiched by strong spunbond nonwoven fabrics. By using a material having air permeability that does not pass body fluid as the back sheet 3, it is possible to reduce stuffiness when worn. The backsheet 3 is bonded to the topsheet 2 using an adhesive such as a hot melt adhesive.
 吸収体4は体液を吸収して保持する。吸収体4は、嵩高であり、型崩れし難く、化学的刺激が少ないものであることが好ましい。たとえば、吸収体4として、フラッフ状パルプもしくはエアレイド不織布と高吸収性ポリマー(SAP)とからなる複合吸収体が使用される。この複合吸収体は、ティッシュなどの液透過性の材料で覆われていてもよい。 The absorber 4 absorbs and holds the body fluid. It is preferable that the absorber 4 is bulky, hard to lose its shape, and less in chemical stimulation. For example, a composite absorbent made of fluff pulp or air-laid non-woven fabric and super absorbent polymer (SAP) is used as the absorbent 4. The composite absorber may be covered with a liquid permeable material such as a tissue.
 また、上記複合吸収体のフラッフ状パルプの代わりに、たとえば、化学パルプ、セルロース繊維、レーヨンおよびアセテートなどの人工セルロース繊維を使用してもよい。上記複合吸収体中のパルプなどの吸収性繊維の坪量は、好ましくは100g/m2以上、800g/m2以下であり、上記複合吸収体中の高吸収性ポリマーの質量比は、吸収性繊維を100%として好ましくは10%以上、65%以下である。上記複合混合体を覆うティッシュなど液透過性の材料の坪量は、好ましくは12g/m2以上、30g/m2以下である。 Also, instead of the fluff pulp of the composite absorbent, artificial cellulose fibers such as chemical pulp, cellulose fibers, rayon and acetate may be used. The basis weight of the absorbent fiber such as pulp in the composite absorbent is preferably 100 g / m 2 or more and 800 g / m 2 or less, and the mass ratio of the superabsorbent polymer in the composite absorbent is the absorbency The fiber content is preferably 100% to 10% to 65%. The basis weight of a liquid-permeable material such as a tissue covering the composite mixture is preferably 12 g / m 2 or more and 30 g / m 2 or less.
 上記複合混合体のエアレイド不織布として、たとえば、パルプと合成繊維とを熱融着させた不織布またはパルプと合成繊維とをバインダーで固着させた不織布を使用することができる。 As the air-laid non-woven fabric of the composite mixture, for example, a non-woven fabric in which pulp and synthetic fibers are heat-sealed or a non-woven fabric in which pulp and synthetic fibers are fixed with a binder can be used.
 上記複合吸収体の高吸収性ポリマーは、水溶性高分子が適度に架橋した三次元網目構造を有する。この吸収性ポリマーは、水を吸収する前の吸収性ポリマーの体積に対して30~60倍の水を吸収する。しかし、この吸収性ポリマーは本質的に水不溶性である。また、この吸収性ポリマーは、多少の圧力を加えられても、一旦吸収された水を離水しない。この吸収性ポリマーとして、たとえば、デンプン系、アクリル酸系またはアミノ酸系の粒子状または繊維状のポリマーが使用される。 The superabsorbent polymer of the composite absorbent has a three-dimensional network structure in which a water-soluble polymer is appropriately crosslinked. The absorbent polymer absorbs 30 to 60 times as much water as the volume of absorbent polymer before absorbing water. However, this absorbable polymer is essentially water insoluble. Also, the absorbent polymer does not release the water once absorbed, even if some pressure is applied. As this absorbent polymer, for example, starch-based, acrylic acid-based or amino acid-based particulate or fibrous polymers are used.
 吸収体4の形状および構造は必要に応じて変えることができるが、吸収体4の全吸収量は、吸収性物品1としての設計挿入量および所望の用途に対応させる必要がある。また、吸収体4のサイズや吸収能力などは用途に応じて変わる。 The shape and structure of the absorber 4 can be changed as needed, but the total amount of absorption of the absorber 4 needs to correspond to the designed insertion amount as the absorbent article 1 and the desired application. In addition, the size, absorption capacity and the like of the absorber 4 change depending on the application.
 ホットメルト接着剤を使用して吸収体4はトップシート2と接着している。これによりトップシート2が吸収体4から剥がれることを抑制できる。 Absorber 4 is bonded to top sheet 2 using a hot melt adhesive. Thereby, it can suppress that the top sheet 2 peels from the absorber 4. As shown in FIG.
 サイドシート5は、体液がトップシート2の表面および/または内部を通って吸収性物品1の幅方向外側へ漏れることを防止する。サイドシート5は、疎水性または撥水性を有することが好ましい。サイドシート5には、たとえば、スパンボンド不織布やSMS不織布などが使用される。また、サイドシート5は着用者の肌と接触するため、肌への擦れ刺激を低減できるエアスルー不織布をサイドシート5に使用することが好ましい。なお、吸収性物品1は、サイドシート5を有さなくてもよい。 The side sheets 5 prevent the body fluid from leaking outward in the width direction of the absorbent article 1 through the surface and / or the inside of the top sheet 2. The side sheets 5 preferably have hydrophobicity or water repellency. For the side sheet 5, for example, a spunbonded nonwoven fabric or an SMS nonwoven fabric is used. In addition, since the side sheet 5 contacts the skin of the wearer, it is preferable to use an air through non-woven fabric capable of reducing rubbing irritation to the skin for the side sheet 5. The absorbent article 1 may not have the side sheet 5.
 上述したように、ウイング部6は、吸収性物品1を下着に安定して固定するために吸収性物品1に設けられている。ウイング部6を下着の外面側に折り曲げた後、粘着部7を介して下着のクロッチ域に張り付けることによって、吸収性物品1を下着に安定して固定することができる。また、本体部10に設けられた粘着部7を下着のクロッチ域に張り付けることによって、着用中に本体部10がずれることを抑制できる。 As described above, the wing portion 6 is provided on the absorbent article 1 in order to stably fix the absorbent article 1 to the undergarment. The absorbent article 1 can be stably fixed to the undergarment by bending the wing portion 6 to the outer surface side of the undergarment and then sticking it to the crotch region of the undergarment through the adhesive portion 7. Moreover, by sticking the adhesive part 7 provided in the main-body part 10 to the crotch area | region of underwear, it can suppress that the main-body part 10 shifts | deviates during wear.
 図2に示す吸収性物品1の粘着部7は、吸収性物品1を下着のクロッチ域に固定する。粘着部7を形成する粘着剤としては、たとえばスチレン系ポリマー、粘着付与剤、可塑剤のいずれかが主成分であるものが好適に使用される。前記スチレン系ポリマーとしては、スチレン-エチレン-ブチレン-スチレンブロック共重合体、スチレン-ブチレン重合体、スチレン-ブチレン-スチレンブロック共重合体、スチレン-イソブチレン-スチレン共重合体などが挙げられるが、これらのうち1種のみを使用しても、二種以上のポリマーブレンドであってもよい。この中でも熱安定性が良好であるという点で、スチレン-エチレン-ブチレン-スチレンブロック共重合体が好ましい。 The adhesive part 7 of the absorbent article 1 shown in FIG. 2 fixes the absorbent article 1 to the crotch area of the undergarment. As an adhesive which forms the adhesion part 7, what is a styrene-type polymer, a tackifier, and a plasticizer as a main component, for example is used suitably. Examples of the styrene-based polymer include styrene-ethylene-butylene-styrene block copolymer, styrene-butylene polymer, styrene-butylene-styrene block copolymer, and styrene-isobutylene-styrene copolymer. Or a blend of two or more polymers. Among these, styrene-ethylene-butylene-styrene block copolymer is preferable in that the thermal stability is good.
 また、前記粘着付与剤および可塑剤としては、常温で固体のものを好ましく用いることができ、粘着付与剤ではたとえばC5系石油樹脂、C9系石油樹脂、ジシクロペンタジエン系石油樹脂、ロジン系石油樹脂、ポリテルペン樹脂、テルペンフェノール樹脂などが挙げられ、前記可塑剤ではたとえば、リン酸トリフレシル、フタル酸ジブチル、フタル酸ジオクチルなどのモノマー可塑剤の他、ビニル重合体やポリエステルのようなポリマー可塑剤が挙げられる。 Further, as the tackifier and the plasticizer, those which are solid at normal temperature can be preferably used, and as the tackifier, for example, C5 petroleum resin, C9 petroleum resin, dicyclopentadiene petroleum resin, rosin petroleum resin And polyterpene resins, terpene phenol resins, etc., and examples of the plasticizer include, in addition to monomer plasticizers such as triflecil phosphate, dibutyl phthalate and dioctyl phthalate, polymer plasticizers such as vinyl polymers and polyesters. Be
 図1および図2に示すように、トップシート2および吸収体4は、エンボス加工により厚み方向に圧縮して形成された、トップシート2から吸収体4の内部に至る圧搾溝8を有する。圧搾溝8は、吸収性物品1の中心部分(着用者の体液の***口に当接する部分)に排出された体液が幅方向(X方向)に拡散するのを抑制する。また、これにより吸収体4からトップシート2が剥がれることを抑制できる。圧搾溝8は、吸収性物品1の中心部分を囲み、連続的な略環状の形状を有する。なお、吸収性物品1の中央部を囲む圧搾溝8は、部分的に途切れていてもよい。すなわち、圧搾溝8は、非連続的な略環状の形状を有していてもよい。 As shown in FIGS. 1 and 2, the top sheet 2 and the absorbent body 4 have compressed grooves 8 extending from the top sheet 2 to the inside of the absorbent body 4 which are formed by being compressed in the thickness direction by embossing. The squeeze groove 8 suppresses the diffusion of the body fluid discharged to the central portion of the absorbent article 1 (the portion in contact with the excretory port of the wearer's body fluid) in the width direction (X direction). Moreover, it can suppress that the top sheet 2 peels from the absorber 4 by this. The squeeze groove 8 surrounds the central portion of the absorbent article 1 and has a continuous, substantially annular shape. In addition, the pressing groove 8 surrounding the center part of the absorbent article 1 may be partially disconnected. That is, the pressing groove 8 may have a discontinuous and substantially annular shape.
 また、ヒートエンボス加工によりトップシート2をバックシート3に圧縮接合させることによって、本体部10の長手方向両側の縁の部分およびウイング部6の幅方向外側の縁の部分にシール部9が形成される。これにより、トップシート2がバックシート3から剥がれないようにできる。さらに、ヒートエンボス加工によってバックシート3とサイドシート5とはウイング部6のシール部9で接合されている。これにより、サイドシート5がバックシート3から剥がれないようにできる。 Further, the compression bonding of the top sheet 2 to the back sheet 3 by heat embossing forms the seal portion 9 on the edge portions on both sides in the longitudinal direction of the main body portion 10 and the edge portion on the width direction outer side of the wing portion 6 Ru. Thereby, the top sheet 2 can be prevented from peeling off from the back sheet 3. Furthermore, the back sheet 3 and the side sheet 5 are joined at the seal portion 9 of the wing portion 6 by heat embossing. Thereby, the side sheet 5 can be prevented from coming off from the back sheet 3.
 次に、上述の血液改質剤を詳細に説明する。血液改質剤は、血液改質剤は、約0.00~約0.60のIOBと、約45℃以下の融点と、25℃の水100gに対する、約0.00~約0.00~約0.05gの水溶解度とを有する。 Next, the above-mentioned blood modifying agent will be described in detail. The blood modifying agent is about 0.00 to about 0.00 to about 100 g of water having a melting point of about 45 ° C. or less and an IOB of about 0.00 to about 0.60, and 100 g of water at 25 ° C. It has a water solubility of about 0.05 g.
 IOB(Inorganic Organic Balance)は、親水性および親油性のバランスを示す指標であり、本明細書では、小田らによる次式:
 IOB=無機性値/有機性値
により算出される値を意味する。
IOB (Inorganic Organic Balance) is an index showing the balance of hydrophilicity and lipophilicity, and in the present specification, the following equation by Oda et al .:
IOB = value calculated by inorganic value / organic value.
 上記無機性値と、有機性値とは、藤田穆「有機化合物の予測と有機概念図」化学の領域Vol.11,No.10(1957)p.719-725)に記載される有機概念図に基づく。藤田氏による、主要な基の有機性値および無機性値を、下記表1にまとめる。 The above inorganic values and organic values are described in Satoshi Fujita, "Presence of Organic Compounds and Organic Conceptual Diagram", Chemistry Vol. 11, No. 10 (1957) p. Based on the organic conceptual diagram described in 719-725). The organic and inorganic values of the major groups by Mr. Fujita are summarized in Table 1 below.
Figure JPOXMLDOC01-appb-T000001
Figure JPOXMLDOC01-appb-T000001
 たとえば、炭素数14のテトラデカン酸と、炭素数12のドデシルアルコールとのエステルの場合には、有機性値が520(CH2,20×26個)、無機性値が60(-COOR,60×1個)となるため、IOB=0.12となる。 For example, in the case of an ester of C14 tetradecanoic acid and C12 dodecyl alcohol, the organic value is 520 (CH 2 , 20 × 26) and the inorganic value is 60 (-COOR, 60 ×). Therefore, IOB = 0.12.
 上記血液改質剤において、IOBは、約0.00~約0.60であり、約0.00~約0.50であることが好ましく、約0.00~約0.40であることがより好ましく、そして約0~約0.30であることがさらに好ましい。IOBが低いほど、有機性が高く、血球との親和性が高くなると考えられるからである。 In the above blood modifying agent, the IOB is about 0.00 to about 0.60, preferably about 0.00 to about 0.50, and about 0.00 to about 0.40. More preferred is about 0 to about 0.30. This is because the lower the IOB, the higher the organicity and the higher the affinity to blood cells.
 本明細書において、「融点」は、示差走査熱量分析計において、昇温速度10℃/分で測定した場合の、固形状から液状に変化する際の吸熱ピークのピークトップ温度を意味する。上記融点は、たとえば、島津製作所社製のDSC-60型DSC測定装置を用いて測定することができる。 In the present specification, the "melting point" means the peak top temperature of an endothermic peak when changing from solid state to liquid state when measured at a temperature rising rate of 10 ° C./min in a differential scanning calorimeter. The melting point can be measured, for example, using a DSC-60 type DSC measurement apparatus manufactured by Shimadzu Corporation.
 上記血液改質剤は、約45℃以下の融点を有すれば、室温で液体であっても、または固体であってもよい、すなわち、融点が約25℃以上でも、または約25℃未満でもよく、そしてたとえば、約-5℃、約-20℃等の融点を有することができる。上記血液改質剤の融点が約45℃以下である根拠は、後述する。 The blood modifying agent may be liquid or solid at room temperature as long as it has a melting point of about 45 ° C. or less, ie, even if the melting point is about 25 ° C. or more, or less than about 25 ° C. It may well have a melting point such as, for example, about -5.degree. C., about -20.degree. The reason why the melting point of the blood modifying agent is about 45 ° C. or less will be described later.
 上記血液改質剤は、その融点に下限は存在しないが、その蒸気圧が低いことが好ましい。上記血液改質剤の蒸気圧は、1気圧および25℃で約0.00~約0.01Paであることが好ましく、約0.000~約0.001Paであることがより好ましく、そして約0.0000~約0.0001Paであることがさらに好ましい。本開示の吸収性物品が、人体に接して用いられることを考慮すると、上記蒸気圧は、1気圧および40℃で約0.00~約0.01Paであることが好ましく、約0.000~約0.001Paであることがより好ましく、そして約0.0000~約0.0001Paであることがさらに好ましい。蒸気圧が高いと、保存中に気化し、血液改質剤の量の減少、着用時の臭気等の問題が発生する場合があるからである。 Although there is no lower limit to the melting point of the blood modifying agent, it is preferable that its vapor pressure is low. The vapor pressure of the blood modifying agent is preferably about 0.00 to about 0.01 Pa at 1 atm and 25 ° C., more preferably about 0.000 to about 0.001 Pa, and about 0 More preferably, it is from .0000 to about 0.0001 Pa. Considering that the absorbent article of the present disclosure is used in contact with the human body, the vapor pressure is preferably about 0.00 to about 0.01 Pa at 1 atm and 40 ° C., and about 0.000 to about 0.01 More preferably, it is about 0.001 Pa, and more preferably, about 0.0000 to about 0.0001 Pa. If the vapor pressure is high, it may be vaporized during storage, which may cause problems such as a decrease in the amount of blood modifying agent and an odor when worn.
 また、血液改質剤の融点を、気候、着用時間の長さ等に応じて、使い分けることができる。たとえば、平均気温が約10℃以下の地域では、約10℃以下の融点を有する血液改質剤を採用することにより、経血が***された後、周囲温度によって冷却された場合であっても、血液改質剤が、安定して血液を改質することができると考えられる。また、吸収性物品が長時間にわたって使用される場合には、血液改質剤の融点は、45℃以下の範囲で高い方が好ましい。汗、着用時の摩擦等の影響を受けにくく、長時間着用した場合であっても、血液改質剤が移動しにくいからである。 In addition, the melting point of the blood modifying agent can be properly used depending on the weather, the length of wearing time, and the like. For example, in areas where the average temperature is less than about 10 ° C, menstrual blood may be excreted and then cooled by the ambient temperature by employing a blood modifying agent having a melting point of less than about 10 ° C. It is believed that blood modifying agents can stably modify blood. When the absorbent article is used for a long time, the melting point of the blood modifying agent is preferably higher in the range of 45 ° C. or less. It is because it is hard to be affected by sweat, friction at the time of wearing, etc., and it is difficult for the blood modifying agent to move even when worn for a long time.
 0.00~0.05gの水溶解度は、25℃において、100gの脱イオン水に、0.05gの試料を添加し、24時間静置し、24時間後に、必要に応じて軽く攪拌し、次いで、試料が溶解したか否か目視で評価することにより測定することができる。なお、本明細書では、水溶解度に関して、「溶解」には、試料が脱イオン水に完全に溶解し、均一混合物を形成した場合と、試料が完全にエマルション化した場合とが含まれる。なお、「完全」とは、脱イオン水に、試料の塊が存在しないことを意味する。 For a water solubility of 0.00 to 0.05 g, add a 0.05 g sample to 100 g deionized water at 25 ° C., allow to stand for 24 hours, and after 24 hours, lightly stir as needed, Then, it can be measured by visually evaluating whether the sample has dissolved. As used herein, with regard to water solubility, "dissolving" includes cases where the sample is completely dissolved in deionized water to form a homogeneous mixture and cases where the sample is completely emulsified. "Complete" means that there is no clump of sample in deionized water.
 当技術分野では、血液の表面張力等を変化させ、血液を迅速に吸収することを目的として、トップシートの表面を、界面活性剤でコーティングすることが行われている。しかし、界面活性剤は、一般に水溶解度が高いため、界面活性剤がコーティングされたトップシートは、血液中の親水性成分(血漿等)となじみがよく、むしろ血液をトップシートに残存させるようにはたらく傾向がある。上記血液改質剤は、水溶解度が低いため、従来公知の界面活性剤と異なり、血液をトップシートに残存させず、迅速に吸収体に移行させることができると考えられる。 In the art, the surface of the top sheet is coated with a surfactant for the purpose of changing blood surface tension and the like to rapidly absorb the blood. However, since the surfactant generally has high water solubility, the surfactant-coated top sheet is compatible with hydrophilic components (such as plasma) in the blood, rather the blood remains on the top sheet. There is a tendency to work. Since the above-mentioned blood modifying agent has low water solubility, unlike the conventionally known surfactants, it is considered that blood can be rapidly transferred to the absorber without remaining on the top sheet.
 本明細書において、25℃における、100gの水に対する溶解度を、単に、「水溶解度」と称する場合がある。 In the present specification, the solubility in 100 g of water at 25 ° C. may be simply referred to as “water solubility”.
 本明細書において、「重量平均分子量」は、多分散系の化合物(たとえば、逐次重合により製造された化合物、複数の脂肪酸と、複数の脂肪族1価アルコールとから生成されたエステル)と、単一化合物(たとえば、1種の脂肪酸と、1種の脂肪族1価アルコールから生成されたエステル)とを含む概念であり、Ni個の分子量Miの分子(i=1、またはi=1,2・・・)からなる系において、次の式:

 なお、本発明者が確認したところ、ポリエチレングリコール(式(23)において、m=2のホモポリマーに相当する)は、n≧45(重量平均分子量約2,000超)の場合に、約0.00~約0.60のIOBの要件を満たすものの、重量平均分子量が約4,000を超えた場合であっても、水溶解度の要件を満たさなかった。したがって、(e1)ポリオキシC2~C6アルキレングリコールには、エチレングリコールのホモポリマーは含まれないと考えられ、エチレングリコールは、他のグリコールとのブロックコポリマー又はランダムコポリマーとして、(e1)ポリオキシC2~C6アルキレングリコールに含まれるべきである。 As confirmed by the present inventor, polyethylene glycol (corresponding to a homopolymer of m = 2 in the formula (23)) is about 0 when n045 (weight average molecular weight is more than about 2,000). Even though the weight average molecular weight exceeded about 4,000, it did not meet the requirement of water solubility, although it met the requirement of an IOB of .00 to about 0.60. Therefore, (e 1 ) polyoxy C 2 -C 6 alkylene glycol is considered not to include homopolymers of ethylene glycol, and ethylene glycol (e 1 ) as a block copolymer or random copolymer with other glycols It should be included in the polyoxy C 2 -C 6 alkylene glycol.
 したがって、式(23)のホモポリマーには、プロピレングリコール、ブチレングリコール、ペンチレングリコール又はヘキシレングリコールのホモポリマーが含まれうる。以上より、式(23)において、mは、約3~約6であり、そして約4~約6であることがより好ましく、そしてnは2以上である。 Thus, homopolymers of formula (23) may include homopolymers of propylene glycol, butylene glycol, pentylene glycol or hexylene glycol. From the above, in the formula (23), m is about 3 to about 6, and more preferably about 4 to about 6, and n is 2 or more.
 上記式(23)において、nの値は、ポリC2~C6アルキレングリコールが、約0.00~約0.60のIOBと、約45℃以下の融点と、25℃の水100gに対する、約0.00~約0.05gの水溶解度とを有するような値である。たとえば、式(23)がポリプロピレングリコール(m=3のホモポリマー)である場合には、n=12の場合に、IOBが0.58となる。したがって、式(23)がポリプロピレングリコール(m=3のホモポリマー)である場合には、m≧約12の場合に、上記IOBの要件を満たす。また、式(21)がポリブチレングリコール(m=4のホモポリマー)である場合には、n=7の場合に、IOBが0.57となる。したがって、式(23)がポリブチレングリコール(m=4のホモポリマー)である場合には、n≧約7の場合に、上記IOBの要件を満たす。 In the above formula (23), the value of n is that the poly C 2 -C 6 alkylene glycol has an IOB of about 0.00 to about 0.60, a melting point of about 45 ° C. or less, and 100 g of water at 25 ° C. It is a value that has a water solubility of about 0.00 to about 0.05 g. For example, when formula (23) is polypropylene glycol (m = 3 homopolymer), IOB is 0.58 when n = 12. Therefore, when the formula (23) is polypropylene glycol (m = 3 homopolymer), the above IOB requirement is satisfied when m ≧ about 12. In the case where the formula (21) is polybutylene glycol (m = 4 homopolymer), the IOB is 0.57 when n = 7. Therefore, when the formula (23) is polybutylene glycol (m = 4 homopolymer), the above IOB requirement is satisfied when n ≧ about 7.
 IOB、融点および水溶解度の観点から、ポリオキシC2~C6アルキレングリコールの重量平均分子量は、好ましくは約200~約10,000、より好ましくは約250~約8,000、そしてさらに好ましくは、約250~約5,000の範囲にある。また、IOB、融点および水溶解度の観点から、ポリC3アルキレングリコール、すなわち、ポリプロピレングリコールの重量平均分子量は、好ましくは約1,000~約10,000、より好ましくは約3,000~約8,000、そしてさらに好ましくは、約4,000~約5,000の範囲にある。上記重量平均分子量が約1,000未満では、水溶解度が要件を満たさず、そして重量平均分子量が大きいほど、特に、吸収体移行速度およびトップシートの白さが向上する傾向があるからである。 From the viewpoint of IOB, melting point and water solubility, the weight average molecular weight of the polyoxy C 2 -C 6 alkylene glycol is preferably about 200 to about 10,000, more preferably about 250 to about 8,000, and more preferably It is in the range of about 250 to about 5,000. Also, in view of IOB, melting point and water solubility, the weight average molecular weight of the poly C 3 alkylene glycol, ie, polypropylene glycol, is preferably about 1,000 to about 10,000, more preferably about 3,000 to about 8 And more preferably in the range of about 4,000 to about 5,000. When the weight average molecular weight is less than about 1,000, the water solubility does not satisfy the requirements, and the larger the weight average molecular weight, the more the absorber transfer rate and the top sheet whiteness tend to be improved.

 上記血液改質剤は、実施例と共に詳細に考察するが、血液の粘度および表面張力を下げる作用を少なくとも有することが見いだされた。吸収性物品が吸収すべき経血は、通常の血液と比較して、子宮内膜壁等のタンパク質を含むため、それらが血球同士を繋ぐように作用して、血球が連銭した状態をとりやすい。そのため、吸収性物品が吸収すべき経血は、高粘度となりやすく、トップシートが不織布または織布である場合には、経血が繊維の間に目詰まりしやすく、着用者はベタつき感を覚えやすく、そしてトップシートの表面で経血が拡散し、漏れやすくなる。 The blood modifying agent, as discussed in detail in conjunction with the examples, has been found to at least have the effect of reducing blood viscosity and surface tension. Since the menstrual blood to be absorbed by the absorbent article contains proteins such as the endometrial wall as compared with normal blood, they act to connect the blood cells to each other, and the blood cells are in a continuous state. Cheap. Therefore, the menstrual blood to be absorbed by the absorbent article tends to have a high viscosity, and when the top sheet is a non-woven fabric or a woven fabric, menstrual blood tends to be clogged between fibers, and the wearer feels sticky. And it spreads and leaks on the surface of the top sheet.
 また、IOBが約0.00~約0.60である血液改質剤は、有機性が高く、血球の間に入り込みやすいので、血球を安定化させ、血球に連銭構造を形成しにくくすることができると考えられる。上記改質剤が、血球を安定化させ、血球に連銭構造を形成しにくくすることにより、吸収体が経血を吸収しやすくなると考えられる。たとえば、アクリル系高吸収ポリマー、いわゆる、SAPを含む吸収性物品では、経血を吸収すると、連銭した血球がSAP表面を覆い、SAPが吸収性能を発揮しにくくなることが知られているが、血球を安定化することにより、SAPが吸収性能を発揮しやすくなると考えられる。また、赤血球と親和性の高い血液改質剤が、赤血球膜を保護するため、赤血球が破壊されにくくなると考えられる。 In addition, a blood modifying agent having an IOB of about 0.00 to about 0.60 is highly organic and easily enters between blood cells, thereby stabilizing the blood cells and making it difficult for the blood cells to form a continuous structure. It is thought that can be done. It is considered that the absorber makes it easy to absorb menstrual blood by stabilizing the blood cells and making the blood cells less likely to form a continuous structure. For example, it is known that in absorbent articles containing an acrylic superabsorbent polymer, the so-called SAP, when menstrual blood is absorbed, blood cells that have undergone continuous change cover the SAP surface, making it difficult for the SAP to exhibit its absorption performance. By stabilizing blood cells, it is considered that SAP can more easily exhibit absorption performance. In addition, it is considered that the blood modifying agent having high affinity for red blood cells protects the red blood cell membrane, so that the red blood cells are less likely to be destroyed.
 トップシート2への血液改質剤の塗工目付は、好ましくは1~30g/m2であり、より好ましくは、3~10g/m2である。血液改質剤の塗工目付が1g/m2よりも小さいと、血液改質剤をトップシート2に安定的に塗布することが難しい場合があり、血液改質剤の塗工目付が30g/m2よりも大きいと、トップシート2がぬるぬるする場合がある。 The coating weight of the blood modifying agent on the top sheet 2 is preferably 1 to 30 g / m 2 , more preferably 3 to 10 g / m 2 . When the coating weight of the blood modifying agent is smaller than 1 g / m 2 , it may be difficult to stably apply the blood modifying agent to the top sheet 2, and the coating weight of the blood modifying agent is 30 g / m. If it is larger than m 2 , the top sheet 2 may be slimy.
 血液改質剤は、所望の温度に加熱した後、スロットコーターなどの接触式コーターや、スプレーコーター、カーテンコーター、スパイラルコーターなどの非接触式コーターを使用して、トップシート2に塗布される。血液改質剤塗布領域8に液滴状の血液改質剤を均一に分散できる点、およびトップシート2にダメージを与えない点から、非接触式コーターを使用して血液改質剤をトップシート2に塗布することが好ましい。 The blood modifier is heated to a desired temperature and then applied to the top sheet 2 using a contact coater such as a slot coater or a noncontact coater such as a spray coater, a curtain coater, or a spiral coater. From the point of being able to uniformly disperse the droplet-like blood modifying agent in the blood modifying agent application region 8 and from the point of not damaging the top sheet 2, the non-contact coater is used to use the non-contact coater It is preferable to apply to 2.
 トップシート用の不織布を作製するときに、血液改質剤を不織布に塗布してもよい。また、吸収性物品1の製造工程で、血液改質剤をトップシート2に塗布するようにしてもよい。しかし、設備投資を抑制できることから、吸収性物品1の製造工程で、血液改質剤をトップシート2に塗布することが好ましい。また、吸収性物品1の製造工程の間に、トップシート2に塗布した血液改質剤が減少することを抑制するために、吸収性物品1の完成に近い工程で血液改質剤をトップシート2に塗布することが好ましい。たとえば、吸収性物品1を包装する工程の直前に、血液改質剤をトップシート2に塗布してもよい。 The blood modifying agent may be applied to the non-woven fabric when making the non-woven fabric for the top sheet. In addition, a blood modifying agent may be applied to the top sheet 2 in the manufacturing process of the absorbent article 1. However, it is preferable to apply a blood modifying agent to the top sheet 2 in the manufacturing process of the absorbent article 1 because equipment investment can be suppressed. Moreover, in order to suppress the reduction of the blood modifying agent applied to the top sheet 2 during the manufacturing process of the absorbent article 1, the blood modifying agent is used as the top sheet in a process close to the completion of the absorbent article 1. It is preferable to apply to 2. For example, a blood modifying agent may be applied to the top sheet 2 immediately before the step of packaging the absorbent article 1.
 図5は、包装するためにウイング部6が折り畳まれた吸収性物品1を説明するための図であるである。以上の構成要素を有する吸収性物品1を包装する場合、図5に示すように一対のウイング部6を幅方向内側に折り畳む。 FIG. 5 is a view for explaining the absorbent article 1 in which the wing portion 6 is folded for packaging. When packaging the absorbent article 1 which has the above component, as shown in FIG. 5, a pair of wing part 6 is folded inside in the width direction.
 粘着部7は剥離シート33によって被覆される。これにより、吸収性物品1の使用前の粘着部7を保護することができる。剥離シート33は、粘着部7の粘着剤に対して剥離可能であるシートであればとくに限定されない。剥離シート33には、たとえば、剥離剤を基材に塗布したものを使用することができる。剥離剤を塗布する基材には、ポリプロピレン、低密度ポリエチレン、ポリビニルアルコールなどのフィルム、不織布、紙などがあり、剥離剤には、シリコーン系、フッ素系、イソシアネートなどがある。 The adhesive portion 7 is covered by a release sheet 33. Thereby, the adhesion part 7 before use of the absorbent article 1 can be protected. The release sheet 33 is not particularly limited as long as it is a sheet that can be released to the adhesive of the adhesive unit 7. As the release sheet 33, for example, one obtained by applying a release agent to a substrate can be used. Examples of the substrate to which the release agent is applied include films of polypropylene, low density polyethylene, polyvinyl alcohol and the like, nonwoven fabrics, paper and the like, and examples of the release agent include silicones, fluorines and isocyanates.
 図5に示すように、吸収性物品1を包装するとき、ウイング部6を折り畳んだ吸収性物品1を、包装材31の上に配置する。包装材31は、たとえば不織布または樹脂フィルムである。また、包装材31の長手方向の端には、止着テープ32が設けられている。包装材31上に配置された吸収性物品1は、包装材31と一緒に、B-B線およびC-C線に沿って長手方向(Y方向)に折り畳まれる。そして、止着テープ32を使用して、吸収性物品1の折り畳まれた状態を維持する。そして、吸収性物品1と一緒に折り畳んだ包装材31の幅方向の両側31aをヒートエンボス加工によって接合する。これにより、吸収性物品1を含む、図6に示す包装品30が作製される。図6は、吸収性物品を含む包装品30の斜視図である。 As shown in FIG. 5, when the absorbent article 1 is packaged, the absorbent article 1 in which the wing portion 6 is folded is placed on the packaging material 31. The packaging material 31 is, for example, a non-woven fabric or a resin film. Further, a fastening tape 32 is provided at an end of the packaging material 31 in the longitudinal direction. The absorbent article 1 disposed on the packaging material 31 is folded along with the packaging material 31 in the longitudinal direction (Y direction) along the lines BB and CC. The fastening tape 32 is then used to maintain the absorbent article 1 in a folded state. Then, both sides 31 a in the width direction of the packaging material 31 folded together with the absorbent article 1 are joined by heat embossing. Thereby, the package 30 shown in FIG. 6 including the absorbent article 1 is produced. FIG. 6 is a perspective view of a package 30 including an absorbent article.
 図7は、図5のD-D線断面を示す概略断面図である。図7に示すように、ウイング部6を折り畳んだときのウイング部6におけるサイドシート5は、トップシート2の血液改質剤塗布領域18(図1参照)と接触する。血液改質剤塗布領域18には、血液改質剤が塗布されているので、ウイング部6におけるトップシート2は、血液改質剤と接触することになる。しかし、トップシート2の突部21によって、ウイング部6におけるサイドシート5とトップシート2の血液改質剤塗布領域18との接触面積は小さくなる。これにより、血液改質剤塗布領域18の血液改質剤がウイング部6に浸透して、ウイング部6におけるトップシート2とバックシート3との間の接合力が弱まることを抑制できる。また、血液改質剤塗布領域18の血液改質剤がウイング部6のサイドシート5に転写されて、血液改質剤塗布領域18の血液改質剤の量が減少することを抑制できる。 FIG. 7 is a schematic cross-sectional view showing a cross section taken along line DD of FIG. As shown in FIG. 7, the side sheet 5 in the wing 6 when the wing 6 is folded contacts the blood modifier application region 18 (see FIG. 1) of the top sheet 2. Since the blood modifying agent application region 18 is coated with the blood modifying agent, the top sheet 2 in the wing portion 6 comes in contact with the blood modifying agent. However, the contact area between the side sheet 5 in the wing portion 6 and the blood modifying agent application region 18 of the top sheet 2 is reduced by the protrusion 21 of the top sheet 2. As a result, it is possible to suppress that the blood modifying agent in the blood modifying agent application region 18 penetrates into the wing portion 6 and the bonding strength between the top sheet 2 and the back sheet 3 in the wing portion 6 is weakened. In addition, it is possible to suppress the reduction of the amount of the blood modifying agent in the blood modifying agent application region 18 due to the blood modifying agent in the blood modifying agent application region 18 being transferred to the side sheet 5 of the wing portion 6.
 上述したように、突部21の中央部23の繊維密度は、突部21の側部24および/または凹部22の繊維密度よりも低い(図3参照)。ところで、トップシート2の血液改質剤塗布領域18に塗布された血液改質剤は、トップシート2の繊維密度の高いところに集まる傾向がある。トップシート2において、ウイング部6と接触する突部21の中央部23の繊維密度は突部21の側部および凹部22に比べて低いので、突部21の中央部23には、血液改質剤はあまり多く集まらない。したがって、突部21の側部24および/または凹部22の繊維密度に比べて突部21の中央部23の繊維密度を低くすることによってウイング部6に転写する血液改質剤の量をさらに減少させることができる。 As described above, the fiber density of the central portion 23 of the projection 21 is lower than the fiber density of the side 24 and / or the recess 22 of the projection 21 (see FIG. 3). By the way, the blood modifying agent applied to the blood modifying agent application region 18 of the top sheet 2 tends to be collected at a place where the fiber density of the top sheet 2 is high. In the top sheet 2, the fiber density of the central portion 23 of the protrusion 21 in contact with the wing portion 6 is lower than that of the side portion of the protrusion 21 and the recess 22. Agents do not collect much. Therefore, the amount of blood modifying agent transferred to the wing portion 6 is further reduced by lowering the fiber density of the central portion 23 of the projection 21 as compared with the fiber density of the side portion 24 of the projection 21 and / or the recess 22 It can be done.
 以上の本発明の一実施形態の吸収性物品1を次のように変形することができる。
(1)図8に示すトップシート2Aように、トップシート2Aの凹部22Aに開口部26Aを形成してもよい。図8(a)は、トップシート2に形成した突部、凹部および開口部を拡大した斜視図であり、図8(b)は、トップシート2に形成した突部、凹部および開口部を拡大した平面図である。開口部26A側面の繊維密度は、突部21Aの中央部23Aの繊維密度よりも高いことが好ましい。これにより、トップシートに塗布された血液改質剤は、凹部22Aに形成された開口部26Aの周囲に多く集まるので、ウイング部6と接触する突部21の中央部23には、血液改質剤は多く集まらない。したがって、開口部26A側面の繊維密度を、突部21Aの中央部23Aの繊維密度よりも高くすることによって、ウイング部6を折り畳んだときにおけるウイング部6に転写する血液改質剤の量を減少させることができる。これにより、トップシート2Aに塗布された血液改質剤がウイング部6に浸透することによりウイング部6を構成するサイドシート5がバックシート3から剥離することを抑制できる。
The absorbent article 1 according to the embodiment of the present invention described above can be modified as follows.
(1) As in the top sheet 2A shown in FIG. 8, the opening 26A may be formed in the recess 22A of the top sheet 2A. FIG. 8A is an enlarged perspective view of a protrusion, a recess, and an opening formed on the top sheet 2. FIG. 8B is an enlarged view of the protrusion, the recess, and the opening formed on the top sheet 2. FIG. The fiber density of the side surface of the opening 26A is preferably higher than the fiber density of the central portion 23A of the protrusion 21A. As a result, a large amount of blood modifying agent applied to the top sheet gathers around the opening 26A formed in the recess 22A, so that the central portion 23 of the protrusion 21 in contact with the wing 6 is modified with blood. Many agents do not collect. Therefore, by making the fiber density of the side surface of the opening 26A higher than the fiber density of the central portion 23A of the projection 21A, the amount of blood modifying agent transferred to the wing 6 when the wing 6 is folded is reduced. It can be done. As a result, the blood modifying agent applied to the top sheet 2A penetrates the wing portion 6 to suppress peeling of the side sheet 5 constituting the wing portion 6 from the back sheet 3.
 たとえば、図9に示すように、幅方向(CD)に延び、機械方向(MD)に並ぶ、通気性を有さない複数の細長状部材160を網状支持部材130に設けることによって、トップシート2Aの凹部22Aに開口部26Aを形成できる。網状支持部材130の細長状部材160が設けられていない部分では、吹き出し部140から噴射した気体141は網状支持部材130を通過するので、ウェブ120に溝122が形成できる程度に、ウェブ120の繊維は掻き分けられる。一方、網状支持部材130の細長状部材160が設けられている部分では、吹き出し部140から噴射した気体141は網状支持部材130を通過せず、細長状部材160で止まるので、ウェブ120の繊維は、ウェブ120に開口部が形成できる程、強く掻き分けられる。これにより、トップシート2Aの凹部22Aに開口部26Aが形成される。開口部26A側面には、掻き分けられた繊維が密集するので、開口部26A側面の繊維密度は高くなる。 For example, as shown in FIG. 9, the top sheet 2A is provided by providing the mesh support member 130 with a plurality of elongated members 160 extending in the width direction (CD) and aligned in the machine direction (MD) and not having air permeability. The opening 26A can be formed in the recess 22A. Since the gas 141 jetted from the blowout part 140 passes through the mesh-like support member 130 in the portion where the elongated member 160 of the mesh-like support member 130 is not provided, the fibers of the web 120 can be formed to the extent that the groove 122 can be formed in the web 120 Are separated. On the other hand, at the portion where the elongated member 160 of the reticulated support member 130 is provided, the gas 141 injected from the blowout portion 140 does not pass through the reticular support member 130 and stops at the elongated member 160. As the openings can be formed in the web 120, they are scraped off strongly. Thus, the opening 26A is formed in the recess 22A of the top sheet 2A. Since scraped fibers are densely packed on the side face of the opening 26A, the fiber density on the side face of the opening 26A is high.
(2)図10に示すトップシート2Bのように、トップシート2Bを構成する不織布を波状に折り曲げることによって、トップシート2Bに、所定方向に延在し、所定方向に交差する方向に並ぶ突部21Bおよび凹部22Bを形成するようにしてもよい。図10は、トップシートの変形例の概略斜視図である。たとえば、一対のギアロールの間に不織布を通過させることによって、波状に折り曲げられたトップシート2Bを作製することができる。また、図11に示すように、不織布を波状に折り曲げることによって突部21Cおよび凹部22Cを形成したトップシート2Cの凹部22Cに開口部26Cを形成してもよい。 (2) As in the top sheet 2B shown in FIG. 10, by bending the non-woven fabric constituting the top sheet 2B in a wave shape, the protrusions extending in the predetermined direction on the top sheet 2B and aligned in the direction intersecting the predetermined direction 21B and the recess 22B may be formed. FIG. 10 is a schematic perspective view of a modification of the top sheet. For example, by passing the non-woven fabric between the pair of gear rolls, it is possible to produce the top sheet 2B folded in a wavelike manner. Further, as shown in FIG. 11, the opening 26C may be formed in the recess 22C of the top sheet 2C in which the protrusion 21C and the recess 22C are formed by bending the nonwoven fabric in a wave shape.
 図11(a)はトップシートの変形例の概略斜視図であり、図11(b)はトップシートの変形例の概略平面図である。たとえば、針状、円筒形状および円錐形状などの形状の複数の突起を外周の表面に有する突起ロールと、突起ロールの突起に対応する位置に突起と嵌合する凹部を外周の表面に有するアンビルロールとの間に、波状に折り曲げられた不織布を通過させることによって、凹部22Cに開口部26Cを形成したトップシートを作製することができる。突起ロールの突起が不織布を貫通することによって開口部26Cが形成されるので、開口部26Cが形成されるとき開口部26C側面に圧力がかかる。したがって、開口部26C側面の繊維密度は、突部21Cの中央部23Cの繊維密度よりも高くなる。したがって、トップシート2Cに塗布された血液改質剤は、トップシート2Cの凹部22Cの開口部26C側面に集まるので、ウイング部6を折り畳んだときにおけるウイング部6に転写する血液改質剤の量を減少させることができる。これにより、トップシート2Cに塗布された血液改質剤がウイング部6に浸透することによりウイング部6を構成するサイドシート5がバックシート3から剥離することを抑制できる。 Fig.11 (a) is a schematic perspective view of the modification of a top sheet, FIG.11 (b) is a schematic plan view of the modification of a top sheet. For example, a projection roll having a plurality of projections in a needle shape, a cylindrical shape, and a conical shape on the outer peripheral surface, and an anvil roll having a recess on the outer peripheral surface that engages with the projection at a position corresponding to the projections of the projection roll. A top sheet having the opening 26C formed in the recess 22C can be manufactured by passing the non-woven fabric folded in a wave shape between them. The openings 26C are formed by the projections of the projection rolls penetrating the non-woven fabric, so that pressure is applied to the side surfaces of the openings 26C when the openings 26C are formed. Therefore, the fiber density of the side surface of the opening 26C is higher than the fiber density of the central portion 23C of the protrusion 21C. Therefore, since the blood modifying agent applied to the top sheet 2C gathers on the side surface of the opening 26C of the recess 22C of the top sheet 2C, the amount of the blood modifying agent transferred to the wing 6 when the wing 6 is folded. Can be reduced. Thereby, when the blood modifier applied to top sheet 2C penetrates to wing part 6, it can control that side sheet 5 which constitutes wing part 6 exfoliates from back sheet 3.
(3)図12に示すように、トップシート2Dから吸収体4Dの内部に至る圧縮部8Dを吸収性物品1Dに形成することによって、ウイング部6を折り畳んだときのウイング部6とトップシート2の血液改質剤塗布領域18との間の接触面積を小さくするようにしてもよい。図12は、図1のA-A線に対応する吸収性物品1Dの概略断面図である。これにより、ウイング部6を折り畳んだとき、トップシート2の血液改質剤塗布領域18からウイング部6に転写する血液改質剤の量を減少させることができる。吸収性物品1Dに形成する圧縮部8Dは、線状の圧縮部でも点状の圧縮部でもよい。圧縮部8Dは、たとえばエンボス加工によって吸収性物品1Dに形成できる。 (3) As shown in FIG. 12, the wing portion 6 and the top sheet 2 when the wing portion 6 is folded by forming the compression portion 8D from the top sheet 2D to the inside of the absorbent 4D into the absorbent article 1D. The contact area with the blood modifying agent application area 18 may be reduced. FIG. 12 is a schematic cross-sectional view of an absorbent article 1D corresponding to the line AA of FIG. As a result, when the wing portion 6 is folded, the amount of the blood modifying agent transferred from the blood modifying agent application region 18 of the top sheet 2 to the wing portion 6 can be reduced. The compression part 8D formed in the absorbent article 1D may be a linear compression part or a point-like compression part. Compression part 8D can be formed in absorptive article 1D, for example by embossing.
 圧縮部8Dは、トップシート2Dおよび吸収体4Dを厚さ方向に圧縮して形成するので、圧縮部8Dの底付近のトップシート2Dおよび吸収体4Dの密度は高くなる。このため、トップシート2Dに塗布された血液改質剤は、圧縮部8Dの底の方に集まるので、ウイング部6を折り畳んだとき、トップシート2の血液改質剤塗布領域18からウイング部6に転写する血液改質剤の量をさらに減少させることができる。これにより、トップシート2Dに塗布された血液改質剤がウイング部6に浸透することによりウイング部6を構成するサイドシート5がバックシート3から剥離することを抑制できる。なお、圧縮部8Dを形成するとき、圧縮部8Dのトップシート2Dがフィルム化すると、トップシート2Dには血液改質剤が浸透しなくなるので、圧縮部8Dにおけるトップシート2Dはフィルム化していないことが好ましい。 Since the compression section 8D is formed by compressing the top sheet 2D and the absorber 4D in the thickness direction, the density of the top sheet 2D and the absorber 4D near the bottom of the compression section 8D is high. For this reason, the blood modifying agent applied to the top sheet 2D gathers toward the bottom of the compression unit 8D. Therefore, when the wing 6 is folded, the blood modifying agent application region 18 of the top sheet 2 starts from the wing 6 The amount of blood modifying agent to be transferred to can be further reduced. Thereby, when the blood modifier applied to top sheet 2D penetrates into wing part 6, it can control that side sheet 5 which constitutes wing part 6 exfoliates from back sheet 3. When forming the compression section 8D, if the top sheet 2D of the compression section 8D is formed into a film, the blood modifying agent does not permeate into the top sheet 2D, so the top sheet 2D in the compression section 8D is not formed into a film Is preferred.
(4)トップシート2の血液改質剤塗布領域18とウイング部6との間の接触面積を低減することができれば、トップシート2の血液改質剤塗布領域18に形成する突部は、上述の突部に限定されない。たとえば、幅方向(X方向)に延在し、長手方向(Y方向)に並ぶ突部をトップシート2の血液改質剤塗布領域18に設けてもよい。また、波状の形態で長手方向(Y方向)または幅方向(X方向)に延在する突部をトップシート2の血液改質剤塗布領域18に設けてもよい。さらに、円柱、角柱、半球などの形状の突部をトップシート2の血液改質剤塗布領域18に設けてもよい。 (4) If the contact area between the blood modifier application area 18 of the top sheet 2 and the wing portion 6 can be reduced, the projection formed on the blood modifier application area 18 of the top sheet 2 is the above-mentioned. Not limited to the projections of For example, protrusions extending in the width direction (X direction) and aligned in the longitudinal direction (Y direction) may be provided in the blood modifier application region 18 of the top sheet 2. Further, protrusions extending in the longitudinal direction (Y direction) or the width direction (X direction) in a wavelike form may be provided in the blood modifier application region 18 of the top sheet 2. Furthermore, a protrusion having a shape of a cylinder, a prism, a hemisphere, or the like may be provided in the blood modifying agent application region 18 of the top sheet 2.
(5)トップシート2の血液改質剤塗布領域18とウイング部6との間の接触面積をさらに低減させるために、サイドシート5に突部を形成してもよい。たとえば、図13に示す吸収性物品1Eのように、波状に折り曲げることによって形成した長手方向に延在する突部51をサイドシート5Eに設けてもよい。図13は、図1のA-A線に対応する吸収性物品1Eの概略断面図である。することができれば、トップシート2の血液改質剤塗布領域18に形成する突部は、上述の突部に限定されない。なお、幅方向に延在する突部をサイドシートに設けてもよい。また、波状の形態で長手方向または幅方向に延在する突部をサイドシートに設けてもよい。さらに、円柱、角柱、半球などの形状の突部をサイドシートに設けてもよい。 (5) In order to further reduce the contact area between the blood modifier application region 18 of the top sheet 2 and the wing portion 6, a protrusion may be formed on the side sheet 5. For example, as in the case of the absorbent article 1E shown in FIG. 13, the side sheet 5E may be provided with the longitudinally extending protrusion 51 formed by bending in a wave shape. FIG. 13 is a schematic cross-sectional view of the absorbent article 1E corresponding to the line AA of FIG. If it can do, the protrusion formed in the blood modifier application area 18 of the top sheet 2 is not limited to the above-mentioned protrusion. In addition, you may provide the protrusion extended in the width direction in a side seat. Moreover, you may provide the side sheet with the protrusion extended in a longitudinal direction or the width direction in a wavelike form. Furthermore, a protrusion having a shape of a cylinder, a prism, a hemisphere, or the like may be provided on the side sheet.
(6)トップシートに塗布する組成物は、所定の組成物であれば、血液改質剤に限定されない。たとえば、肌荒れを防ぐローションをトップシートに塗布してもよい。 (6) The composition to be applied to the top sheet is not limited to the blood modifier as long as it is a predetermined composition. For example, a lotion for preventing rough skin may be applied to the top sheet.
 本発明では、血液改質剤が、血液の粘度および表面張力を下げるメカニズムを有するために、体液が、血液改質剤層24によってトップシート2に残存せずに吸収体4へ移動し吸収体4に吸収されることができる。以下の実施例によって、血液改質剤が、血液の粘度および表面張力を下げるメカニズムを有することを確認した。 In the present invention, since the blood modifying agent has a mechanism to lower the viscosity and surface tension of the blood, the body fluid is transferred to the absorber 4 without remaining on the top sheet 2 by the blood modifying layer 24 and absorbed. 4 can be absorbed. The following examples confirmed that the blood modifying agent has a mechanism to lower the viscosity and surface tension of blood.

 上記試料の、IOB,融点および水溶解度を、下記表2に示す。なお、水溶解度は、上述の方法にしたがって測定したが、100gの脱塩水に、20.0gを添加し、24時間後に溶解した試料は、「20g<」と評価し、そして100gの脱塩水に、0.05gは溶解したが、1.00gは溶解しなかった試料は、0.05~1.00gと評価した。また、融点に関し、「<45」は、融点が45℃未満であることを意味する。 The IOB, melting point and water solubility of the above sample are shown in Table 2 below. The water solubility was measured according to the above-mentioned method, but 20.0 g was added to 100 g of demineralized water, and a sample dissolved after 24 hours was evaluated as "20 g <", and 100 g of demineralized water was used. A sample in which 0.05 g was dissolved but not 1.00 g was evaluated as 0.05 to 1.00 g. Moreover, regarding melting | fusing point, "<45" means that melting | fusing point is less than 45 degreeC.
 上記生理用ナプキンのトップシートの肌当接面を、上述の血液改質剤で塗工した。各血液改質剤を、血液改質剤が室温で液体である場合にはそのまま、そして血液改質剤が室温で固体である場合には、融点+20℃まで加熱し、次いで、コントロールシームHMAガンを用いて、各血液改質剤を微粒化し、トップシートの肌当接面の全体に、坪量がおおよそ5g/m2となるように塗布した。 The skin contact surface of the top sheet of the above-mentioned sanitary napkin was coated with the above-mentioned blood modifier. Heat each blood modifier to its melting point + 20 ° C if the blood modifier is liquid at room temperature, and if the blood modifier is solid at room temperature, then control seam HMA gun Each blood modifying agent was atomized and applied to the entire skin contact surface of the top sheet so that the basis weight was approximately 5 g / m 2 .
 図14は、トップシートがトリC2L油脂肪酸グリセリドを含む生理用ナプキン(No.2-5)における、トップシートの肌当接面の電子顕微鏡写真である。図14から明らかなように、トリC2L油脂肪酸グリセリドは、微粒子状で、繊維の表面に付着している。
 上述の手順にしたがって、リウェット率と、吸収体移行速度とを測定した。結果を、下記表2に示す。
FIG. 14 is an electron micrograph of the skin contact surface of the top sheet in the sanitary napkin (No. 2-5) in which the top sheet contains avian C2L oil fatty acid glyceride. As apparent from FIG. 14, the tri-C2L oil fatty acid glyceride is in the form of fine particles and adheres to the surface of the fiber.
Rewet rates and absorber transfer rates were measured according to the procedure described above. The results are shown in Table 2 below.
[試験方法]
 各血液改質剤を含むトップシートの上に、穴の開いたアクリル板(200mm×100mm,125g,中央に、40mm×10mmの穴が開いている)を置き、上記穴から、37±1℃のウマEDTA血(ウマの血液に、凝結防止のため、エチレンジアミン四酢酸(以下、「EDTA」と称する)が添加されたもの)3gを、ピペットを用いて滴下(1回目)し、1分後、37±1℃のウマEDTA血3gを、アクリル板の穴から、ピペットで再度滴下した(2回目)。
[Test method]
Place a perforated acrylic plate (200 mm x 100 mm, 125 g, with a 40 mm x 10 mm hole in the center) on the top sheet containing each blood modifying agent, and from the holes, 37 ± 1 ° C 3g of equine EDTA blood (into the blood of the horse, ethylenediaminetetraacetic acid (hereinafter referred to as "EDTA") added to prevent coagulation) was dropped (first time) using a pipette, and one minute later Then, 3 g of equine EDTA blood at 37 ± 1 ° C. was pipetted again from the hole of the acrylic plate (second time).
 2回目の血液の滴下後、直ちに上記アクリル板を外し、血液を滴下した場所に、ろ紙(アドバンテック東洋株式会社 定性濾紙 No.2,50mm×35mm)10枚を置き、その上から、圧力が30g/cm2となるようにおもりを置いた。1分後、上記ろ紙を取出し、以下の式に従って、「リウェット率」を算出した。
 リウェット率(%)=100×(試験後のろ紙質量-当初のろ紙質量)/6
After the second drop of blood, immediately remove the above acrylic plate and place 10 sheets of filter paper (Advantec Toyo Co., Ltd. Qualitative filter paper No. 2, 50 mm x 35 mm) in the place where the blood is dropped, and 30 g of pressure from above The weight was placed to be / cm 2 . One minute later, the filter paper was taken out, and the "rewet rate" was calculated according to the following equation.
Rewet rate (%) = 100 × (weight of filter paper after test−weight of original filter paper) / 6
 また、リウェット率の評価とは別に、2回目の血液の滴下後、血液がトップシートから吸収体に移行する時間である「吸収体移行速度」を測定した。上記吸収体移行速度は、トップシートに血液を投入してから、トップシートの表面及び内部に、血液の赤さが見られなくなるまでの時間を意味する。
 リウェット率と、吸収体移行速度の結果を、以下の表2に示す。
In addition to the evaluation of the rewet rate, “absorber transfer speed”, which is the time for blood to transfer from the top sheet to the absorber after the second drop of blood, was measured. The above-mentioned absorber transfer rate means the time from when blood is introduced into the top sheet to when the red color of blood is not seen on the surface and inside of the top sheet.
The results of the rewet rate and the absorber transfer rate are shown in Table 2 below.
 次いで、吸収体移行速度の試験後のトップシートの肌当接面の白さを、以下の基準にしたがって、目視で評価した。
 ◎:血液の赤さがほとんど残っておらず、血液が存在した場所と、存在していない場所の区別がつかない
 ○:血液の赤さが若干残っているが、血液の存在した場所と、存在していない場所の区別がつきいにくい
 △:血液の赤さが若干残っており、血液が存在した場所が分かる
 ×:血液の赤さがそのまま残っている
 結果を、併せて下記表2に示す。
Next, the whiteness of the skin contact surface of the top sheet after the test of the absorber transfer speed was visually evaluated according to the following criteria.
◎: Almost no blood red remains, and there is no distinction between where blood was present and where it did not exist ○: Some blood red remains, but where blood was present, It is difficult to distinguish where it does not exist :: Some redness of the blood remains, and the place where the blood exists is known ×: The redness of the blood remains The results are also shown in Table 2 below. Show.

 血液改質剤を有しない場合には、リウェット率は22.7%であり、そして吸収体移行速度は60秒超であったが、グリセリンと脂肪酸とのトリエステルは、いずれも、リウェット率が7.0%以下であり、そして吸収体移行速度が8秒以下であることから、吸収性能が大幅に改善されていることが分かる。しかし、グリセリンと脂肪酸とのトリエステルのうち、融点が45℃を超えるNA50では、吸収性能に大きな改善はみられなかった。 In the absence of a blood modifying agent, the rewet rate was 22.7% and the absorber transfer rate was over 60 seconds, but both the glycerin and fatty acid triesters had rewet rates From the fact that it is 7.0% or less and the absorber transfer rate is 8 seconds or less, it can be seen that the absorption performance is greatly improved. However, among triesters of glycerin and fatty acid, NA50 of which the melting point exceeds 45 ° C. shows no significant improvement in the absorption performance.
 同様に、約0.00~約0.60のIOBと、約45℃以下の融点と、25℃の水100gに対する、約0.00~約0.05gの水溶解度を有する血液改質剤では、吸収性能が大きく改善されることが分かった。 Similarly, a blood modifying agent having an IOB of about 0.00 to about 0.60, a melting point of about 45 ° C. or less, and an aqueous solubility of about 0.00 to about 0.05 g per 100 g of water at 25 ° C. It was found that the absorption performance was greatly improved.
 次に、No.2-1~2-47の生理用ナプキンを、複数のボランティアの被験者に着用してもらったところ、No.2-1~2-32の血液改質剤を含む生理用ナプキンでは、経血を吸収した後であってもトップシートにべたつき感がなく、トップシートがサラサラしているとの回答を得た。 Next, No. No. 2 to No. 2-2-47 sanitary napkins were worn by a plurality of volunteer subjects. With sanitary napkins containing blood modifiers 2-1 to 2-3, there was no tackiness on the top sheet even after menstrual blood absorption, and it was answered that the top sheet was smooth. .
 また、No.2-1~No.2-32の生理用ナプキンでは、そして特に、No.2-1~11,15~19および32の血液改質剤を含む生理用ナプキンでは、経血を吸収後のトップシートの肌当接面が、血液で赤く染まっておらず、不快感が少ないとの回答を得た。 Also, no. 2-1 to No. No. 2-32 sanitary napkins, and in particular. In the sanitary napkins containing blood modifiers 2-1 to 11, 15 to 19 and 32, the skin contact surface of the top sheet after absorption of menstrual blood is not stained red with blood and there is less discomfort I got an answer with.

[Evaluation of blood retention]
The blood retention of the top sheet containing the blood modifying agent and the top sheet not containing the blood modifying agent was evaluated.
[試験方法]
(1)エアスルー不織布(ポリエステルおよびポリエチレンテレフタレートから成る複合繊維、坪量:35g/m2)から形成されたトップシートの肌当接面に、トリC2L油脂肪酸グリセリドを、コントロールシームHMAガンを用いて微粒化し、坪量がおおよそ5g/m2となるように塗布する。また、比較のため、トリC2L油脂肪酸グリセリドを塗布していないものも準備する。次いで、トリC2L油脂肪酸グリセリドが塗布されているトップシートと、塗布されていないトップシートとの両方を、0.2gの大きさにカットし、セルストレイナー+トップシートの質量(a)を正確に測定する。
[Test method]

Figure JPOXMLDOC01-appb-T000014
 血液改質剤を含むトップシートは、血液保持性が低く、血液を吸収後、迅速に吸収体に移行させることができることが示唆される。 It is suggested that the top sheet containing the blood modifying agent has low blood retention and can be rapidly transferred to the absorber after absorbing blood.
[例4]
[血液改質剤を含む血液の粘性]
 血液改質剤を含む血液の粘性を、Rheometric Expansion System ARES(Rheometric Scientific,Inc)を用いて測定した。ウマ脱繊維血に、パナセート810sを2質量%添加し、軽く撹拌して試料を形成し、直径50mmのパラレルプレートに試料を載せ、ギャップを100μmとし、37±0.5℃で粘度を測定した。パラレルプレートゆえ、試料に均一なせん断速度はかかっていないが、機器に表示された平均せん断速度は、10s-1であった。
[Example 4]
[Viscosity of blood containing blood modifying agent]
The viscosity of the blood containing the blood modifying agent was measured using Rheometric Expansion System ARES (Rheometric Scientific, Inc). 2% by weight of Panaceto 810s was added to equine defibrinated blood, the mixture was lightly stirred to form a sample, the sample was loaded on a parallel plate of 50 mm in diameter, the gap was made 100 μm, and the viscosity was measured at 37 ± 0.5 ° C. . Because of the parallel plate, the sample was not subjected to a uniform shear rate, but the average shear rate displayed on the instrument was 10 s −1 .
 パナセート810sを2質量%含むウマ脱繊維血の粘度は、5.9mPa・sであり、一方、血液改質剤を含まないウマ脱繊維血の粘度は、50.4mPa・sであった。したがって、パナセート810sを2質量%含むウマ脱繊維血は、血液改質剤を含まない場合と比較して、約90%粘度を下げることが分かる。血液は、血球等の成分を含み、チキソトロピーの性質を有することが知られているが、本開示の血液改質剤は、低粘度域で、血液の粘度を下げることができると考えられる。血液の粘度を下げることにより、吸収した経血を、トップシートから吸収体に速やかに移行させることができると考えられる。 The viscosity of horse-defibrillated blood containing 2% by mass of Panaceto 810s was 5.9 mPa · s, while the viscosity of horse-defibrillated blood containing no blood modifying agent was 50.4 mPa · s. Thus, it can be seen that equine defibrinated blood containing 2% by weight of Panaceto 810s reduces the viscosity by about 90% as compared to the case without blood modifying agent. Although blood contains components such as blood cells and is known to have thixotropy properties, it is considered that the blood modifying agent of the present disclosure can lower the viscosity of blood in a low viscosity region. By reducing the viscosity of blood, it is thought that absorbed menstrual blood can be rapidly transferred from the top sheet to the absorber.

[血液改質剤を含む血液の顕微鏡写真]
 健常ボランティアの経血をサランラップ(商標)上に採取し、その一部に、10倍の質量のリン酸緩衝生理食塩水中に分散されたパナセート810sを、パナセート810sの濃度が1質量%となるように添加した。経血を、スライドグラスに適下し、カバーグラスをかけ、光学顕微鏡にて、赤血球の状態を観察した。血液改質剤を含まない経血の顕微鏡写真を図15(a)に、そしてパナセート810sを含む経血の顕微鏡写真を図15(b)に示す。
[Example 5]
[Micrograph of blood containing blood modifier]
A healthy volunteer's menstrual blood is collected on Saran wrap (trademark), and a portion of it is Panaseto 810s dispersed in 10 times mass phosphate buffered saline, and the concentration of Panaceto 810s is 1% by mass. Added to The menstrual blood was applied to a slide glass, covered with a cover glass, and the condition of red blood cells was observed with a light microscope. A photomicrograph of menstrual blood containing no blood modifying agent is shown in FIG. 15 (a), and a photomicrograph of menstrual blood containing PANACET 810s is shown in FIG. 15 (b).
 図15から、血液改質剤を含まない経血では、赤血球が連銭等の集合塊を形成しているが、パナセート810sを含む経血では、赤血球が、それぞれ、安定に分散していることが分かる。したがって、血液改質剤は、血液の中で、赤血球を安定化させる働きをしていることが示唆される。 From FIG. 15, in menstrual blood containing no blood modifying agent, red blood cells form a lump of rhomsen, etc., but in menstrual blood containing PANACET 810s, each red blood cell is stably dispersed. I understand. Therefore, it is suggested that the blood modifying agent works to stabilize red blood cells in the blood.

[血液改質剤を含む血液の表面張力]

The surface tension of blood containing a blood modifying agent was measured by a pendant drop method using a contact angle meter Drop Master 500 manufactured by Kyowa Interface Science Co., Ltd. The surface tension was measured after adding a predetermined amount of blood modifying agent to sheep defibrinated blood and shaking sufficiently. The measurement is automatically performed by the device, but the density γ is obtained by the following equation (see FIG. 16).
 γ=g×ρ×(de)2×1/H
 g:重力定数
 1/H:ds/deから求められる補正項
 ρ:密度
 de:最大直径
 ds:滴下端よりdeだけ上がった位置での径
γ = g × ρ × (de) 2 × 1 / H
g: Gravitational constant 1 / H: correction term obtained from ds / de ρ: density de: maximum diameter ds: diameter at a position de up from the dropping end
 密度ρは、JIS K 2249-1995の「密度試験方法および密度・質量・容量換算表」の5.振動式密度試験方法に準拠し、下記表5に示される温度で測定した。測定には、京都電子工業株式会社のDA-505を用いた。結果を、表5に示す。 The density ρ is the density test method and density / mass / volume conversion table in JIS K 2249-1995, 5. It was measured at the temperature shown in Table 5 below according to the vibrational density test method. For measurement, DA-505 of Kyoto Electronics Industries Ltd. was used. The results are shown in Table 5.

 表5から、血液改質剤は、25℃の水100gに対する、約0.00~約0.05gの水溶解度を有することからも明らかなように、水への溶解性が非常に低いが、血液の表面張力を下げることができることが分かる。血液の表面張力を下げることにより、吸収した血液をトップシートの繊維間に保持せず、速やかに吸収体に移行させることができると考えられる。 From Table 5, it is apparent from the fact that the blood modifying agent has a water solubility of about 0.00 to about 0.05 g per 100 g of water at 25 ° C., but its solubility in water is very low. It can be seen that the surface tension of the blood can be reduced. By lowering the surface tension of the blood, it is considered that the absorbed blood can be rapidly transferred to the absorber without being held between the fibers of the top sheet.
