Examples of the liquid-impermeable film include a film made of polyethylene, polypropylene, polyester, nylon, polyvinyl alcohol, cellophane, vinyl chloride and the like, or a multilayer film thereof and the like.
　（４）吸収体
　吸収体４は、図３に示すように、トップシート２とバックシート３との間に配置され、体液を吸収し、吸収した体液を保持する。吸収体４は、吸収性ポリマー（ＳＡＰ；Superabsorbent polymer）を含むＳＡＰシート４０である。ここでいうＳＡＰシート４０とは、ＳＡＰを有するシート状の部材を意味する。本実施形態に係るＳＡＰシート４０は、ＳＡＰが分散した不織布（例えば、エアレイド法による不織布（すなわち、エアレイド不織布））で構成されている。 (4) Absorber As shown in FIG. 3, the absorber 4 is arranged between the top sheet 2 and the back sheet 3, absorbs the body fluid, and holds the absorbed body fluid. The absorber 4 is a SAP sheet 40 containing an absorbent polymer (SAP). The SAP sheet 40 referred to here means a sheet-like member having SAP. The SAP sheet 40 according to the present embodiment is composed of a non-woven fabric in which SAP is dispersed (for example, a non-woven fabric produced by the air-laid method (that is, an air-laid non-woven fabric)).
　ただし、ＳＡＰシートとしては、ＳＡＰが分散した不織布を吸収層とし、これを支持シートと被覆シートとで挟んで積層して、シート状に構成されてもよい。この場合、例えば以下のように構成される。 However, as the SAP sheet, a non-woven fabric in which SAP is dispersed may be used as an absorbent layer, which may be sandwiched between a support sheet and a covering sheet and laminated to form a sheet. In this case, for example, it is configured as follows.
　支持シートはバックシート３に対向するシートであり、ＳＡＰを有する吸収層を支持する。被覆シートは、ＳＡＰシート４０を表側から被覆するシートであり、液透過性を有する。被覆シートとしては、例えば、セルロース系繊維により形成された紙、ティッシュペーパーが挙げられる。セルロース系繊維としては、例えば、針葉樹や広葉樹等の木材パルプ；古紙パルプ；麻や綿等の非木材パルプ；化学合成パルプ；コットン等由来のセルロース繊維等が挙げられる。また、ポリエステル繊維、ポリアミド繊維、アクリル繊維、ポリプロピレン繊維、ポリエチレン／ポリエステル複合繊維、ポリエチレン／ポリプロピレン複合繊維等の合成繊維を含んでもよい。また、被覆シートには、エンボス加工が施されていてもよい。 The support sheet is a sheet facing the back sheet 3 and supports the absorption layer having SAP. The covering sheet is a sheet that covers the SAP sheet 40 from the front side and has liquid permeability. Examples of the covering sheet include paper and tissue paper formed of cellulosic fibers. Examples of the cellulosic fiber include wood pulp such as softwood and broadleaf tree; used paper pulp; non-wood pulp such as hemp and cotton; chemically synthesized pulp; cellulose fiber derived from cotton and the like. Further, synthetic fibers such as polyester fiber, polyamide fiber, acrylic fiber, polypropylene fiber, polyethylene / polyester composite fiber, and polyethylene / polypropylene composite fiber may be included. Further, the covering sheet may be embossed.
　ＳＡＰシート４０は、平面視矩形状であってもよいし、トップシート２及びバックシート３の外周縁に沿うような外縁を有する形状であってもよい。本実施形態では、トップシート２及びバックシート３の外周縁に沿うような外縁を有する形状を有しており、上記「（１）全体構成」で述べたように、体液吸収性物品１の外周縁と吸収体４との間の寸法が、２０ｍｍ以下となるように設定されている。 The SAP sheet 40 may have a rectangular shape in a plan view, or may have a shape having an outer edge along the outer peripheral edge of the top sheet 2 and the back sheet 3. In the present embodiment, the top sheet 2 and the back sheet 3 have a shape having an outer edge along the outer peripheral edge, and as described in the above "(1) Overall configuration", the outside of the body fluid absorbing article 1. The dimension between the peripheral edge and the absorber 4 is set to be 20 mm or less.
　ＳＡＰシート４０は、吸収性が高い一方で、比較的硬く、柔軟性に乏しい。そのため、ＳＡＰシート４０を用いると、体液吸収性物品１の肌当たりの良さが損なわれる可能性があるが、本実施形態では、ＳＡＰシート４０（吸収体４）とトップシート２との間に、柔軟性をもつ圧縮回復シート５が配置されている。 While the SAP sheet 40 has high absorbency, it is relatively hard and lacks flexibility. Therefore, if the SAP sheet 40 is used, the goodness of the body fluid-absorbing article 1 on the skin may be impaired, but in the present embodiment, between the SAP sheet 40 (absorbent body 4) and the top sheet 2, A flexible compression recovery sheet 5 is arranged.
　（５）圧縮回復シート
　圧縮回復シート５は、吸収体４とトップシート２との間に配置された柔軟性をもつシートである。圧縮回復シート５は、圧縮レジリエンス値（ＲＣ値）が６．５％以上であることが好ましく、より好ましくは、１３％以上であり、更に好ましくは２１％以上である。 (5) Compression recovery sheet The compression recovery sheet 5 is a flexible sheet arranged between the absorber 4 and the top sheet 2. The compression recovery sheet 5 preferably has a compression resilience value (RC value) of 6.5% or more, more preferably 13% or more, and further preferably 21% or more.
　ここで、圧縮レジリエンス値（ＲＣ値）とは、圧縮回復性を示す数値であり、数値が１００％に近いほど圧縮回復性が高い。圧縮レジリエンス値は、圧縮試験機（ＫＥＳ－Ｇ５カトーテック株式会社製）を用いて測定した値を用いて算出することができる。圧縮試験機によって、荷重２０００g/cm2、速度０．１０cm/secで、圧縮回復シート５を圧縮してゆく際と、除荷して圧縮回復シート５が回復してゆく際と、のそれぞれの荷重（gf/cm2）と押込み量(mm)とを測定する。そして、荷重（gf/cm2）と押込み量(mm)との関係をＳＳ曲線で表示し、圧縮してゆくときの力の合計Ｗ１に対する、回復してゆくときの力の合計Ｗ２の比を百分率で算出し、これを圧縮レジリエンス値とする。 Here, the compression resilience value (RC value) is a numerical value indicating compression recovery, and the closer the numerical value is to 100%, the higher the compression recovery. The compression resilience value can be calculated using a value measured using a compression tester (manufactured by KES-G5 Katou Tech Co., Ltd.). When the compression recovery sheet 5 is compressed with a load of 2000 g / cm 2 and a speed of 0.10 cm / sec by a compression tester, and when the compression recovery sheet 5 is recovered by unloading, respectively. Measure the load (gf / cm 2 ) and the amount of indentation (mm). Then, the relationship between the load (gf / cm 2 ) and the pushing amount (mm) is displayed as an SS curve, and the ratio of the total force W2 when recovering to the total force W1 when compressing is calculated. Calculated as a percentage and used as the compression resilience value.
　具体的には、図４に示すように、ＳＳ曲線は、縦軸として、圧縮回復シート５を押し込んだ際の荷重（gf/cm2）とし、横軸として、圧縮回復シート５の変形量である押込み距離(mm)とする。そして、圧縮してゆくときの力の合計Ｗ１として、Ｗ１＝（部分Ａ１の面積）+（部分Ｂ１の面積）とし、回復してゆくときの力の合計Ｗ２として、Ｗ２＝（部分Ｂ１の面積）とし、圧縮レジリエンス値ＲＣの式　ＲＣ＝（Ｗ２／Ｗ１）×１００を用いて算出する。 Specifically, as shown in FIG. 4, the SS curve has the vertical axis representing the load (gf / cm 2 ) when the compression recovery sheet 5 is pushed in, and the horizontal axis representing the amount of deformation of the compression recovery sheet 5. Let it be a certain pushing distance (mm). Then, W1 = (area of partial A1) + (area of partial B1) as the total force W1 when compressing, and W2 = (area of partial B1) as the total force W2 when recovering. ), And the compression resilience value RC is calculated using the formula RC = (W2 / W1) × 100.
　圧縮回復シート５の圧縮レジリエンス値が６．５％以上であると、体液吸収性物品１としての圧縮回復性が高いため、着用者の肌に対して適切な圧での接触を保つことができ、ＳＡＰシート４０を使用することで、体液吸収性物品１として多少硬くなっても、肌触りを向上させることができる。 When the compression resilience value of the compression recovery sheet 5 is 6.5% or more, the compression recovery property of the body fluid-absorbing article 1 is high, so that the contact with the wearer's skin at an appropriate pressure can be maintained. By using the SAP sheet 40, even if the body fluid-absorbing article 1 is slightly hardened, the touch can be improved.
　圧縮回復シート５としては、例えば、織物、編物、不織布、パルプ製品等から構成される繊維構造物、ウレタンスポンジ等の発泡体が用いられる。圧縮回復シート５としては、例えば、天然繊維、又は合成繊維からなる集積体（例えば不織布）が用いられ、天然繊維としては、例えば、綿、シルク、パルプ、羊毛、麻等が挙げられる。また、合成繊維としては、例えば、ナイロン繊維、ポリエチレン繊維、ポリエステル繊維、ポリアミド繊維、アクリル繊維、ポリビニルアルコール繊維、ポリプロピレン繊維、ポリエチレンテレフタレート繊維、エチレン酢酸ビニル繊維、ウレタン繊維等が挙げられ、また、レーヨン繊維、アセテート繊維、キュプラ等の半合成繊維、及び各種繊維の混紡品、混繊品が用いられてもよい。これらは、１種単独で使用されてもよいし、２種以上が組み合わせて使用されてもよい。 As the compression recovery sheet 5, for example, a fiber structure composed of a woven fabric, a knitted fabric, a non-woven fabric, a pulp product, or a foam such as a urethane sponge is used. As the compression recovery sheet 5, for example, an aggregate made of natural fibers or synthetic fibers (for example, a non-woven fabric) is used, and examples of the natural fibers include cotton, silk, pulp, wool, and linen. Examples of the synthetic fiber include nylon fiber, polyethylene fiber, polyester fiber, polyamide fiber, acrylic fiber, polyvinyl alcohol fiber, polypropylene fiber, polyethylene terephthalate fiber, ethylene vinyl acetate fiber, urethane fiber and the like, and rayon. Semi-synthetic fibers such as fibers, acetate fibers and cupra, and blended products and blended products of various fibers may be used. These may be used individually by 1 type, or may be used in combination of 2 or more type.
　不織布は、例えば、湿式抄紙法、乾式抄紙法、スパンボンド法、メルトブロー法、ラテックス樹脂ボンド法、溶剤ボンド法、スティッチボンド法、ニードルパンチ法、スパンレース法、サーマルボンド法、エアスルー法、エアレイド法等の方法により製造することができる。その中でも、高い柔軟性を有する観点から、エアスルー法による不織布（エアスルー不織布という場合がある）が好ましい。 The non-woven fabric is, for example, a wet papermaking method, a dry papermaking method, a spunbond method, a melt blow method, a latex resin bond method, a solvent bond method, a stitch bond method, a needle punch method, a spunlace method, a thermal bond method, an air-through method, and an air-laid method. It can be manufactured by a method such as. Among them, a non-woven fabric by the air-through method (sometimes referred to as an air-through non-woven fabric) is preferable from the viewpoint of having high flexibility.
　また、圧縮回復シート５の厚さ寸法は、２．０mm以上７．３mm以下であることが好ましく、より好ましくは、３．０mm以上７．０mm以下である。圧縮回復シート５としては、弱親水性であることが好ましい。 Further, the thickness dimension of the compression recovery sheet 5 is preferably 2.0 mm or more and 7.3 mm or less, and more preferably 3.0 mm or more and 7.0 mm or less. The compression recovery sheet 5 is preferably weakly hydrophilic.
　本実施形態に係る圧縮回復シート５としては、ＰＥＴとＰＥＴ／ＰＥ（芯：ＰＥＴ　鞘：ＰＥの芯鞘構造）との合成繊維で構成されたエアスルー不織布が用いられる。圧縮回復シート５の目付けは、２０g/m2以上であることが好ましく、より好ましくは４０g/m2以上であり、更に好ましくは６０g/m2以上である。圧縮回復シート５の目付けが２０g/m2に満たない場合、着用者はふんわり感が得られず、肌触りが悪くなりやすい。また、目付けが４０g/m2以上である場合、体液吸収性物品１を着用した着用者は、ふんわり感を得やすい。目付けが６０g/m2以上である場合、体液吸収性物品１を着用した着用者は、十分なふんわり感を得ることができる。「ふんわり感」とは、着用した際の、柔らかくやさしい肌触りを意味する。 As the compression recovery sheet 5 according to the present embodiment, an air-through nonwoven fabric composed of synthetic fibers of PET and PET / PE (core: PET sheath: PE core sheath structure) is used. The basis weight of the compression recovery sheet 5 is preferably 20 g / m 2 or more, more preferably 40 g / m 2 or more, and further preferably 60 g / m 2 or more. If the basis weight of the compression recovery sheet 5 is less than 20 g / m 2 , the wearer does not feel fluffy and tends to feel uncomfortable. Further, when the basis weight is 40 g / m 2 or more, the wearer wearing the body fluid absorbing article 1 tends to obtain a fluffy feeling. When the basis weight is 60 g / m 2 or more, the wearer wearing the body fluid absorbing article 1 can obtain a sufficient fluffy feeling. "Fluffy feeling" means a soft and gentle touch when worn.
　なお、圧縮回復シート５は、柔軟性に加えて、体液の吸収をする機能も有し得るが、一定の荷重条件下で一定の厚さを超えても、吸収力は向上しない。圧縮回復シート５として体液の吸収力向上を期待できる厚さは、例えば、０．５g/cm2の荷重条件下で厚さ２．５mmまでであり、０．５g/cm2の荷重条件下で厚さ２．５mm以上になると、体液の吸収力は向上しないが柔軟性が向上する。 The compression recovery sheet 5 may have a function of absorbing body fluid in addition to flexibility, but the absorption capacity does not improve even if the thickness exceeds a certain value under a certain load condition. The thickness of the compression recovery sheet 5 that can be expected to improve the absorption capacity of body fluid is, for example, up to 2.5 mm under a load condition of 0.5 g / cm 2 , and under a load condition of 0.5 g / cm 2 . When the thickness is 2.5 mm or more, the absorption capacity of body fluid is not improved, but the flexibility is improved.
　（６）粘着層
　粘着層６は、粘着剤をバックシート３に塗布すること等により設けられる。粘着層６に用いられる粘着剤は、体液吸収性物品１を下着等に貼り付けることができるものであれば特に制限されず、例えば、水溶性の接着剤（例えばアクリル系水溶性接着剤）、非水溶性接着剤（例えば、ゴム系ホットメルト、オレフィン系ホットメルト等）等の接着剤が挙げられる。その中でも、その他の粘着剤に比べて下着に対する接着力に優れる点から非水溶性接着剤が好ましく、ゴム系ホットメルトがより好ましい。粘着層６は、バックシート３の全面を覆うように設けられていてもよいし、バックシート３の長さ方向において部分的に設けられてもよい。本実施形態に係る体液吸収性物品１では、図２に示すように、バックシート３の長さ方向において一定の間隔をあけて形成されたストライプ状に形成されて、部分的に設けられている。 (6) Adhesive layer The adhesive layer 6 is provided by applying an adhesive to the back sheet 3 or the like. The pressure-sensitive adhesive used for the pressure-sensitive adhesive layer 6 is not particularly limited as long as it can attach the body liquid-absorbing article 1 to underwear or the like, and is, for example, a water-soluble adhesive (for example, an acrylic water-soluble adhesive). Examples thereof include adhesives such as water-insoluble adhesives (for example, rubber-based hot melts, olefin-based hot melts, etc.). Among them, a water-insoluble adhesive is preferable, and a rubber-based hot melt is more preferable, because it is superior in adhesive strength to underwear as compared with other adhesives. The adhesive layer 6 may be provided so as to cover the entire surface of the back sheet 3, or may be provided partially in the length direction of the back sheet 3. In the body fluid-absorbing article 1 according to the present embodiment, as shown in FIG. 2, the back sheet 3 is formed in a striped shape formed at regular intervals in the length direction, and is partially provided. ..
　（７）圧縮変形率
　上記構成の体液吸収性物品１は、吸収体４とトップシート２との間に圧縮回復シート５が配置されているため、圧縮変形率Ｔが適切な数値となるように設定されており、着用者の使用感が向上する。圧縮変形率Ｔは、体液吸収性物品１の圧縮荷重下における変形のしやすさを示す指標である。 (7) Compression Deformation Rate In the body fluid absorbent article 1 having the above configuration, the compression recovery sheet 5 is arranged between the absorber 4 and the top sheet 2, so that the compression deformation rate T becomes an appropriate value. It is set to improve the usability of the wearer. The compression deformation rate T is an index showing the ease of deformation of the body fluid-absorbing article 1 under a compression load.
　圧縮変形率Ｔは、Ｔ＝（Ｔ１－Ｔ２）／Ｔ１で表される。Ｔ１は、体液吸収性物品１の厚さ方向に沿ってトップシート２側から０．５gf/cm2の荷重をかけたときの体液吸収性物品１の厚さ（mm）である。また、Ｔ２は、体液吸収性物品１の厚さ方向に沿ってトップシート２側から２０００gf/cm2の荷重をかけたときの体液吸収性物品１の厚さ（mm）である。 The compression deformation rate T is represented by T = (T1-T2) / T1. T1 is the thickness (mm) of the body fluid-absorbing article 1 when a load of 0.5 gf / cm 2 is applied from the top sheet 2 side along the thickness direction of the body fluid-absorbing article 1. Further, T2 is the thickness (mm) of the body fluid-absorbing article 1 when a load of 2000 gf / cm 2 is applied from the top sheet 2 side along the thickness direction of the body fluid-absorbing article 1.
　本実施形態に係る体液吸収性物品１では、圧縮変形率Ｔは０．７５以上であることが好ましく、より好ましくは、０．７９以上であり、更に好ましくは０．８１以上であり、更に好ましくは、０．８５以上である。圧縮変形率Ｔが０．７５未満であると、着用者が、硬さを感じて使用感が悪くなりやすい。 In the body fluid-absorbing article 1 according to the present embodiment, the compression deformation rate T is preferably 0.75 or more, more preferably 0.79 or more, still more preferably 0.81 or more, still more preferable. Is 0.85 or more. When the compression deformation rate T is less than 0.75, the wearer tends to feel the hardness and the usability is deteriorated.
　圧縮変形率Ｔは、圧縮試験機（ＫＥＳ－Ｇ５　カトーテック株式会社製）を用いて測定した値を用いて算出することができる。まず、体液吸収性物品１をトップシート２側が上になるように水平な測定台に載せ、体液吸収性物品１に、矩形枠状（外寸Ｌ８cm×Ｗ６cm、内寸Ｌ６cm×Ｗ４cm）の錘を載せる。次に、錘の枠内に位置する体液吸収性物品１の部分（ここでは中央部）に向かって、試験機のセンサを用いて０．１０cm/secの速度で圧縮させてゆく。そして、体液吸収性物品１を圧縮する荷重が、０．５gf/cm2のときの体液吸収性物品１の厚さＴ１（mm）を測定し、また、センサにより体液吸収性物品１を圧縮する荷重が６０gf/cm2のときの体液吸収性物品１の厚さＴ２（mm）を測定する。その後、Ｔ＝（Ｔ１－Ｔ２）／Ｔ１の式を用いて、圧縮変形率Ｔを算出することができる。 The compression deformation rate T can be calculated using a value measured using a compression tester (KES-G5 manufactured by Katou Tech Co., Ltd.). First, the body fluid-absorbing article 1 is placed on a horizontal measuring table so that the top sheet 2 side faces up, and a rectangular frame-shaped (outer size L8 cm x W6 cm, inner size L6 cm x W4 cm) weight is placed on the body fluid-absorbing article 1. Put it on. Next, the body fluid-absorbing article 1 located in the frame of the weight (here, the central portion) is compressed at a speed of 0.10 cm / sec using the sensor of the testing machine. Then, when the load for compressing the body fluid-absorbing article 1 is 0.5 gf / cm 2 , the thickness T1 (mm) of the body fluid-absorbing article 1 is measured, and the body fluid-absorbing article 1 is compressed by the sensor. The thickness T2 (mm) of the body fluid-absorbing article 1 when the load is 60 gf / cm 2 is measured. After that, the compression deformation rate T can be calculated using the equation T = (T1-T2) / T1.
　この圧縮変形率Ｔを算出する際の試験機のセンサが圧縮する体液吸収性物品１における対象部分は、圧着部１１以外の箇所であればどこであってもよいが、着用時に、着用者の体液が排出される部位と対向する領域（「液透過領域」という場合がある）にて計測することが好ましい。液透過領域は、ここでは体液吸収性物品１の中央部を指す。例えば、本実施形態に係るおりものシート１０では、少なくとも液透過領域における圧縮変形率Ｔが、０．７５以上であればよい。ただし、圧着部１１を除いたすべての部分の圧縮変形率Ｔが０．７５以上であればより好ましい。 The target portion of the body fluid-absorbing article 1 compressed by the sensor of the testing machine when calculating the compression deformation rate T may be any place other than the crimping portion 11, but the wearer's body fluid at the time of wearing may be used. It is preferable to measure in a region facing the region where the liquid is discharged (sometimes referred to as a "liquid permeation region"). The liquid permeation region here refers to the central portion of the body fluid absorbent article 1. For example, in the vaginal discharge sheet 10 according to the present embodiment, the compression deformation rate T in at least the liquid permeation region may be 0.75 or more. However, it is more preferable that the compression deformation rate T of all the portions except the crimping portion 11 is 0.75 or more.
　（８）静止摩擦係数
　体液吸収性物品１の表面層となるトップシート２の表面の静止摩擦係数は、次のように設定されており、トップシート２は、肌と接触した状態で、肌に対して滑りにくくなっており、肌に対して擦れることによる刺激を抑えることができる。すなわち、静止摩擦係数は、着用者の肌触りのやさしさに影響を与え得る。本実施形態では、次の滑り開始角度測定方法で測定した滑り開始角度が、α＝３７°以上となるように設定されている。 (8) Static friction coefficient The static friction coefficient of the surface of the top sheet 2 which is the surface layer of the body fluid absorbent article 1 is set as follows, and the top sheet 2 is in contact with the skin and is in contact with the skin. On the other hand, it is less slippery and can suppress irritation caused by rubbing against the skin. That is, the coefficient of static friction can affect the softness of the wearer's touch. In the present embodiment, the slip start angle measured by the following slip start angle measuring method is set to be α = 37 ° or more.
　（滑り開始角度測定方法）
　図５に示すような滑り開始角度測定器７（ボールタック用粘着力測定器　ＹＯＳＨＩＭＩＴＳＵ　ＳＥＩＫＩ製）を用いる。滑り開始角度測定器７は、水平面に対する角度が可変である傾斜板７１の傾斜面７２に対し、バックシート３が対向するように吸収性物品１を接着する。厚さ０．５mmの塩化ビニルシート７３（商品名：ユニサンデー　ＥＢ４３５－１　株式会社光製）を６cm×３cmの長方形状にカットし、当該塩化ビニルシート７３に対して、両面テープを用いて、同じく６cm×３cmの長方形状にカットした共和ライフテクノ株式会社のサラブレッド６０２の人工皮革７４を接着した板体７５を作成し、これを人工皮革７４がトップシート２に対向するようにして、体液吸収性物品１に載せる。 (Slip start angle measurement method)
A slip start angle measuring device 7 (manufactured by YOSHIMITSU SEIKI, an adhesive force measuring device for ball tack) as shown in FIG. 5 is used. The slip start angle measuring device 7 adheres the absorbent article 1 to the inclined surface 72 of the inclined plate 71 whose angle with respect to the horizontal plane is variable so that the back sheet 3 faces. A vinyl chloride sheet 73 with a thickness of 0.5 mm (trade name: Uni-Sunday EB435-1 Kogyo Co., Ltd.) was cut into a 6 cm x 3 cm rectangular shape, and the vinyl chloride sheet 73 was subjected to double-sided tape. Similarly, a plate 75 to which the artificial leather 74 of Sarab Red 602 of Kyowa Life Techno Co., Ltd., which was cut into a rectangular shape of 6 cm × 3 cm, was bonded was created, and the artificial leather 74 was made to face the top sheet 2 to absorb body fluid. Place it on the sex article 1.
　滑り開始角度測定器７の傾斜板７１を、水平な状態（つまり、水平面と傾斜面７２とのなす角度α＝０°）から、水平面と傾斜面７２とでなす角度αが、０．１°／secの速度で大きくなるように動かす。そして、板体７５が滑りを始めたときの水平面と傾斜面７２とでなす角度αを滑り開始角度とする。 The angle α between the horizontal surface and the inclined surface 72 of the inclined plate 71 of the sliding start angle measuring instrument 7 from the horizontal state (that is, the angle α between the horizontal plane and the inclined surface 72 = 0 °) is 0.1 °. Move to increase at a speed of / sec. Then, the angle α formed by the horizontal plane and the inclined surface 72 when the plate body 75 starts to slide is defined as the sliding start angle.
　体液吸収性物品１は、肌触りのやさしさの観点で、滑り開始角度がα＝３７°以上であることが好ましいが、滑り開始角度がα＝４０°以上であることがより好ましい。ただし、本実施形態に係る体液吸収性物品１では、ふんわり感を重視する場合、滑り開始角度がα＝３７°未満であってもよい。 From the viewpoint of softness to the touch, the body fluid absorbing article 1 preferably has a slip start angle of α = 37 ° or more, but more preferably a slip start angle of α = 40 ° or more. However, in the body fluid-absorbing article 1 according to the present embodiment, the slip start angle may be less than α = 37 ° when the fluffy feeling is emphasized.
　＜効果＞
　以上説明したように、本実施形態に係る体液吸収性物品１は、吸収体４とトップシート２との間に圧縮回復シート５があり、圧縮変形率Ｔが０．７５以上であるため、着用した際に、着用者がふんわり感を受けやすく、良好な使用感が得られやすい。また、吸収体にＳＡＰシートを用いているため、高い吸収性を得ることができる。したがって、本実施形態に係る体液吸収性物品１によれば、高い吸収性を保ちながらも良好な使用感が得られやすい。 <Effect>
As described above, the body fluid absorbent article 1 according to the present embodiment is worn because the compression recovery sheet 5 is provided between the absorber 4 and the top sheet 2 and the compression deformation rate T is 0.75 or more. When this is done, the wearer tends to feel fluffy and a good feeling of use is easily obtained. Further, since the SAP sheet is used as the absorber, high absorbability can be obtained. Therefore, according to the body fluid-absorbing article 1 according to the present embodiment, it is easy to obtain a good usability while maintaining high absorbability.
　また、圧縮回復シート５は、圧縮レジリエンス値が６．５％以上であるため、肌に対して、適切な接触圧で接触し続けることができ、高い使用感を得ることができる。また、復元性が高いためヨレが生じにくい。 Further, since the compression recovery sheet 5 has a compression resilience value of 6.5% or more, it can continue to be in contact with the skin at an appropriate contact pressure, and a high usability can be obtained. In addition, since it has high resilience, it is unlikely to be twisted.
　また、圧縮回復シートがエアスルー不織布である場合、ふんわり感が得られやすく、圧縮復元性も高いため、高い使用感が得られやすい。 Also, when the compression recovery sheet is an air-through non-woven fabric, it is easy to obtain a fluffy feeling and high compression stability, so it is easy to obtain a high usability.
　また、吸収体４と体液吸収性物品１の外周縁との間の寸法のいずれもが２０mm以下であるため、体液が漏れにくく、吸収性が高い体液吸収性物品１とすることができる。また、吸収体４と外周縁の寸法が２０mm以下であるため、吸収体４がある部分と体液吸収性物品１全体とで圧縮率に差がなく、ヨレが生じにくい。 Further, since both the dimensions between the absorber 4 and the outer peripheral edge of the body fluid-absorbing article 1 are 20 mm or less, the body fluid is less likely to leak and the body fluid-absorbing article 1 can be made highly absorbent. Further, since the dimensions of the absorber 4 and the outer peripheral edge are 20 mm or less, there is no difference in the compressibility between the portion where the absorber 4 is located and the entire body fluid-absorbing article 1, and twisting is unlikely to occur.
　また、体液吸収性物品の滑り開始角度がα＝３７°以上となるように設定されているため、着用時に、皮膚とトップシート２とが擦れにくく、摩擦による肌への刺激を抑えることができ、使用感を向上させることができる。 In addition, since the slip start angle of the body fluid absorbing article is set to be α = 37 ° or more, the skin and the top sheet 2 are less likely to rub against each other when worn, and the irritation to the skin due to friction can be suppressed. , The feeling of use can be improved.
　＜変形例＞
　上記実施形態は、本発明の様々な実施形態の一つに過ぎない。実施形態は、本発明の目的を達成できれば、設計等に応じて種々の変更が可能である。以下、実施形態の変形例を列挙する。以下に説明する変形例は、適宜組み合わせて適用可能である。 <Modification example>
The above embodiment is only one of various embodiments of the present invention. The embodiment can be variously changed according to the design and the like as long as the object of the present invention can be achieved.

 As a test, the compression deformation rate and the compression resilience value were calculated. In addition, a sensory test for fluffy feeling, a twist deformation rate, a coefficient of static friction, a sensory test for touch, and a test for absorption amount were conducted. The results are shown in Table 1 below.

　表１に示すように、実施例１－５と比較例１－４とから、圧縮変形率が０．７３以下であるとふんわり感が得られにくい一方、ふんわり感を効果的に得るためには、体液吸収性物品の圧縮変形率が０．７５以上とすることが効果的であることが実証できた。 As shown in Table 1, from Example 1-5 and Comparative Example 1-4, when the compression deformation ratio is 0.73 or less, it is difficult to obtain a fluffy feeling, but in order to effectively obtain a fluffy feeling. It was demonstrated that it is effective to set the compression deformation rate of the body fluid-absorbing article to 0.75 or more.
　比較例２と比較例３とを比較すると、圧縮レジリエンス値が、比較例２では、１３．９であったのに対し、比較例３では、６．０２であったが、ヨレ変形率が比較例２では８０％であり、比較例３では７６％であった。したがって、圧縮レジリエンス値が６．０２以下であると、ヨレやすいことがわかった。 Comparing Comparative Example 2 and Comparative Example 3, the compression resilience value was 13.9 in Comparative Example 2 and 6.02 in Comparative Example 3, but the twist deformation rate was compared. In Example 2, it was 80%, and in Comparative Example 3, it was 76%. Therefore, it was found that when the compression resilience value is 6.02 or less, it is easy to twist.
　実施例１と実施例２－５とを比較すると、ＳＡＰシートの端から体液吸収性物品の外縁までの寸法が、実施例１ではいずれも２０mm以下であるのに対し、実施例２－５では、いずれも２０mmより大きいところ、吸収量が、実施例１では２ccであったのに対し、実施例２－５では、１．８ccであった。したがって、吸収体と体液吸収性物品の外周縁との間の寸法が２０mm以下であると、吸収量を多くすることができることが実証できた。また、ヨレ変形率が実施例１では９５％であったのに対し、実施例２－５では８９％以下であった。したがって、吸収体と体液吸収性物品の外周縁との間の寸法が２０mm以下であると、ヨレにくくなることが実証できた。 Comparing Example 1 and Example 2-5, the dimension from the edge of the SAP sheet to the outer edge of the body fluid-absorbing article is 20 mm or less in all of Example 1, whereas in Example 2-5, it is 20 mm or less. Where both were larger than 20 mm, the absorption amount was 1.8 cc in Example 2-5, whereas it was 2 cc in Example 1. Therefore, it was demonstrated that the amount of absorption can be increased when the dimension between the absorber and the outer peripheral edge of the body fluid-absorbing article is 20 mm or less. Further, the twist deformation rate was 95% in Example 1 and 89% or less in Example 2-5. Therefore, it was demonstrated that when the dimension between the absorber and the outer peripheral edge of the body fluid-absorbing article is 20 mm or less, twisting is less likely to occur.
　実施例３と実施例１，２とを比較すると、滑り開始角度が、実施例３では３５°であったのに対し、実施例１，２では、４０°であったところ、肌触りのやさしさが、実施例３では「〇」であったのに対し、実施例１，２では、「◎」であった。トップシートの摩擦力は、トップシートに対して接触する肌との追従性に影響を与えることから、このような結果が出ていると考えられる。したがって、滑り開始角度が３５°以下であると、肌触りのやさしさが、多少損なわれることがわかった。 Comparing Example 3 and Examples 1 and 2, the slip start angle was 35 ° in Example 3, whereas it was 40 ° in Examples 1 and 2, and the softness to the touch was improved. In Example 3, it was "○", whereas in Examples 1 and 2, it was "◎". Since the frictional force of the top sheet affects the followability to the skin in contact with the top sheet, it is considered that such a result is obtained. Therefore, it was found that when the slip start angle is 35 ° or less, the softness to the touch is somewhat impaired.
　実施例４と比較例２とを比較すると、吸収体（ＳＡＰシート）を有する実施例４では、圧縮変形率が０．８１であるのに対し、吸収体が無い比較例２では、圧縮変形率が０．４７である。なお、実施例４と比較例２とでは、吸収体の有無のみが異なっている。このことから、吸収体（ＳＡＰシート）と圧縮回復シートとを重ねることによって、圧縮回復シートのみの場合よりも、圧縮変形率及びふんわり感が改善されることが分かった。 Comparing Example 4 and Comparative Example 2, the compression deformation rate is 0.81 in Example 4 having an absorber (SAP sheet), whereas the compression deformation rate is 0.81 in Comparative Example 2 without an absorber. Is 0.47. It should be noted that only the presence or absence of the absorber differs between Example 4 and Comparative Example 2. From this, it was found that by stacking the absorber (SAP sheet) and the compression recovery sheet, the compression deformation rate and the fluffy feeling are improved as compared with the case of using only the compression recovery sheet.
