More specifically, the wearer brings the first main body adhesive portion 61 into contact with the crotch region of the underwear and causes the second main body adhesive portion 62 to contact with the underwear behind the crotch region.
- the wearer turns the wing 3 back to the non-skin facing surface side T2 of the underwear, and makes the wing adhesive portion 63 abut on the non-skin facing surface of the crotch region of the underwear. Further, the wearer brings the hip flap adhesive portion 64 into contact with the underwear behind the crotch region.
- the wearer places his / her hand on the skin sheet 10, for example, presses the absorbent article 1 against the underwear while tracing the skin-facing surface of the absorbent article 1 with his / her finger and holds the adhesive part 60. Fix through.
- the wearer presses the skin sheet 10 (part A in FIG. 6) in the crotch region S1 with a finger, and then moves the finger backward while tracing the skin sheet 10 with the finger (arrow X in FIG. 6). ), And press the skin sheet 10 (B portion in FIG. 6) in the rear side region S3 with a finger.
- the wearer presses the absorbent article 1 against the underwear at a portion including the first joint from the tip of the finger in order to firmly press the absorbent article 1 against the underwear. By wearing in this way, the absorbent article 1 is fixed to the underwear.
- the wearer Since the non-squeezing region 52 is provided in the rear region S3 of the absorbent article 1 of the present embodiment, the wearer places his / her finger along the rear side from the front side (inseam region side, part A in FIG. 6). When the slide is moved (arrow X in FIG. 6), the non-compressed region 52 is touched (B portion in FIG. 6). When the wearer traces the surface of the absorbent article 1 with a finger, the wearer feels softness without feeling the hardness of the squeezed portion for at least a certain period. Therefore, the wearer can grasp the softness of the absorbent article 1 before wearing, and can obtain a sense of expectation for the comfort of the absorbent article 1.
- the diameter of the fiber of the 1st layer 111 which touches a wearer's hand is comparatively small. Since the first layer 111 is soft to the touch, the wearer can feel softness when touched by hand. Further, when the wearer presses the absorbent article 1 to fix it to the undergarment or the like, a repulsive force is easily obtained by the second layer 112 made of relatively thick fibers. Therefore, when the wearer traces the surface sheet 11 with the finger, the skin facing surface of the surface sheet 11 is pushed back to the finger side by the repulsive force of the second layer 112, and the wearer touches the skin facing surface of the surface sheet 11 with the finger. It becomes easy to continue touching. Since the wearer continues to touch the soft first layer 111, the wearer can continue to feel the softness of the topsheet 11.
- the nonwoven fabric which comprises the core wrap 32 which covers the absorption core 31 has high elongation compared with a tissue. Therefore, when the wearer slides the finger touching the absorbent article 1 or presses the finger with the finger, the nonwoven fabric that is the core wrap 32 extends, and the wearer has the skin facing surface of the absorbent article 1. A feeling of following the hand can be obtained. More specifically, when the finger is traced on the first layer 111 of the top sheet 11, the finger moves on the skin facing surface of the first layer 111. At this time, since the core wrap 32 positioned at the root of the surface touched by the finger has a high elongation, the core wrap 32 as the root extends following the movement of the finger.
- the first layer 111 is pulled by following the movement of the finger, and the finger does not immediately leave the first layer 111, or the first layer It feels as if the fibers of 111 are clinging to the finger and the fibers are slowly separated from the finger. Therefore, the wearer can continue to feel the softness not by the point but by the surface.
- the wearer When the wearer traces the skin facing surface of the absorbent article 1 with a finger, the wearer feels softness without feeling the hardness of the squeezed part for at least a certain period.
- the wearer can grasp the softness of the absorbent article 1 before wearing, and can obtain a sense of expectation for the comfort of the absorbent article 1.
- the finger sensation is sharpened. Therefore, the sensation felt soft with a finger tends to remain with a relatively strong impression in the head. Therefore, the wearer can easily maintain a soft impression during wearing by feeling soft with a finger.
- the rear side area S3 is particularly surely fixed to the underwear. If the rear side area S3 of the absorbent article 1 is not fixed to the absorbent article 1, when the underwear is lifted after wearing, the absorbent article 1 turns over and the absorbent article 1 comes off, or the absorbent article 1 turns over and the adhesive parts stick together. Therefore, the wearer tries to fix the back side area S3 of the absorbent article 1 with his / her finger to fix the underwear. Since the non-squeezing region 52 is provided in the rear side region T3 of the absorbent article 1, when the wearer tries to fix the rear side region S3 with certainty, the wearer can reduce the softness of the absorbent article 1. I can grasp it.
- the non-compressed region 52 overlaps the second main body adhesive portion 62 of the rear side region S3.
- the wearer tries to press the second main body adhesive portion 62 of the rear side region S3 against the underwear when the rear side region S3 is securely fixed to the underwear. Therefore, when the wearer tries to fix the rear side region S3 through the second main body adhesive portion 62 by overlapping the second main body adhesive portion 62 and the non-compressed region 52, the finger is in the non-compressed region. 52 is easy to touch.
- the wearer can grasp the softness of the absorbent article 1 during the mounting operation, and can increase expectations for the absorbent article 1.
- the non-squeezed region 52 may be arranged so as to overlap the low weight portion and the high weight portion 45.
- the wearer traces the skin facing surface of the non-squeezed region 52, the skin facing surface side T1 of both the high weighted portion 45 and the low weighted portion can be traced, and the swelling of the absorbent core 31 can be easily felt by the change in the weight. Become.
- a plurality of the third low weight portions 43 as the width low weight portions may be arranged at intervals in the front-rear direction L.
- the plurality of third low weight portions can be traced.
- the second low weight portion 42 as the front and rear low weight portion may be arranged so as to overlap the non-squeezed region 52.
- the second low weight portion 42 serves as a guide extending in the front-rear direction L, and the wearer can easily slide the hand pressing the crotch region S1 rearward along the second low weight portion 42. The wearer can feel the softness of the absorbent article 1 by touching the non-squeezed region 52 when moving backward along the second low weight portion 42.
- the non-compressed area 52 may be disposed on a virtual line extending in the width direction W from the position P1 having the maximum width of the hip flap 4.
- the wearer tries to securely fix the position P1 of the maximum width of the hip flap 4 that is most swollen in the rear side region S3 in order to prevent the hip flap 4 from being swung. Therefore, the wearer presses with a finger on the position P1 of the maximum width of the hip flap 4 or an imaginary line extending in the width direction W from the position P1 of the maximum width.
- the wearer can easily touch the non-squeezed region 52, and the wearer may feel softness. it can.
- the pressing area 51 may be disposed on the rear side of the position P1 of the maximum width of the hip flap 4 in the width direction W.
- the wearer feels one softness of the absorbent article by the non-squeezed region 52 on the imaginary line extending in the width direction 4 from the position P1 of the maximum width of the hip flap 4.
- a wearer can touch a pressing part by moving a finger back rather than the said non-pressing area
- the wearer can grasp the position of the rear edge of the absorbent article 1 by the change in the hardness of the skin facing surface of the absorbent article 1. Therefore, the wearer can obtain a sense of expectation for the wearing feeling of the absorbent article 1 and can feel secure that it can be securely fixed to the underwear until reaching the rear edge of the absorbent article 1.
- the diameter of the fibers constituting the first layer may be less than 2.0 dtex.
- the outer edge 321E of the first core wrap 321 may be disposed on the outer side in the width direction from the non-skin facing surface side T2 of the absorbent core 31 or the outer edge of the absorbent core 31. In other words, the outer edge 321E of the first core wrap 321 may not be disposed on the skin facing surface side T1 of the absorbent core 31. Without forming a step due to the outer edge of the core wrap 32 on the skin facing surface of the absorbent article 1, it is easy to maintain the skin facing surface of the absorbent article 1 in a smooth state. When the wearer touches the top sheet 11, it is difficult for the wearer to feel a step due to the presence or absence of the core wrap 32, and it becomes easy to obtain a smooth and skin-friendly image.
- the absorbent core 31 may not be partially compressed, and the density of the absorbent material may be constant. Since the portion hardened by the compression is not provided in the absorbent core 31, the entire region where the absorbent core 31 is disposed becomes soft. The wearer can easily feel the softness of the absorbent core 31 and can easily expect the feeling of wearing.
- the absorbent core 31 may have a plurality of areas with different basis weights, and the areas with different basis weights may be configured such that the basis weight changes stepwise. Since the basis weight changes in stages in a plurality of regions, a plurality of irregularities are formed on the skin facing surface of the absorbent article 1. The wearer tends to feel swelling due to the unevenness of the absorbent core 31 when tracing with a finger. Further, the absorbent core 31 is easily deformed with the boundary where the basis weight is changed as a base point, and is easily deformed flexibly following the movement of the body when worn. Therefore, since the absorption core 31 follows the movement of the body, the wearing feeling is improved.
- the nonwoven fabric according to the present invention (Example) and the nonwoven fabric not having the configuration of the present invention (Comparative Example) are comparatively evaluated.
- the experiment was conducted.
- the comparative evaluation experiment in order to evaluate the surface friction and roughness of the nonwoven fabric in order to evaluate the non-woven fabric's rough sliding feeling, the non-woven fabric was evaluated in order to evaluate the hardness and softness of the nonwoven fabric.

Abstract
Description
図1は、一実施形態における吸収性物品の平面図である。図2は、図1とは反対側から見た吸収性物品の平面図である。図3は、図1のA-A線に沿った吸収性物品の断面図である。
次に、吸収体30の構成についてより具体的に説明する。吸収体30は、少なくとも股下域S1に、中高部33を有する。中高部33は、股下域S1から前側域S2へ延びていてもよい。中高部33は、股下域S1において、中心線CLを跨いで配置されている。中心線CLは、吸収性物品1の幅方向Wの中心を通り、前後方向Lに沿って延びる線である。
吸収性物品1は、少なくとも吸収コア31が厚み方向Tに圧縮されることによって形成された圧搾部を有する。この圧搾部は、前側圧搾部81と、長手圧搾部82と、一対の後側圧搾部84と、を有していてよい。
図2に示すように、吸収性物品1には、吸収性物品1を下着に止めるための粘着剤を有する粘着部60が設けられている。粘着部60は、下着に対して吸収性物品1を着脱可能に係合するように構成されており、係合部を構成する。なお、係合部は、粘着部に限定されず、例えばフック部材であってもよい。粘着部60は、第1本体粘着部61、第2本体粘着部62、ウイング粘着部63及びヒップフラップ粘着部64を有する。これらの粘着部61~64は、非肌面シート20の非肌対向面側T2に設けられている。粘着部61~64は、使用前の状態において、剥離シートによって覆われていてもよい。剥離シートは、使用前に粘着部61~64の粘着剤の劣化を防止する。剥離シートは、使用時に、着用者によって取り外される。
次いで、図4に基づいて表面シート11について詳細に説明する。図4は、表面シート11の模式断面図である。表面シート11は、第1層111と、第2層112と、を有する。なお、図1においては、表面シート11を1層で図示するが、詳細には、表面シート11は、図4に示すように2層からなる。第1層111は、吸収性物品1の肌対向面を構成する。第2層112は、第1層111の非肌対向面側T2に配置される。第1層111と第2層112は、不織布である。第2層112を構成する繊維の径は、第1層111を構成する繊維の径よりも太い。具体的には、第1層111の繊維の径は、1.3dtexであり、第2層112の繊維の径は、2.2dtexである。より好適には、第1層111の繊維の径は、0.5dtex以上2.0dtex未満であることが好ましい。第1層111の繊維の径が0.5dtex以上であることにより、当該繊維を用いて不織布を安定して製造できる。また、第1層111の繊維の径が2.0dtex未満であることにより、着用者が指で触れた際に柔らかさを感じ易く、後述する実施例においても好適な評価を得ることができた。
次に、圧搾領域51と非圧搾領域52について説明する。図5は、図1に示す吸収性物品1の平面図において圧搾領域51と非圧搾領域52を示した図である。図5において圧搾領域51と非圧搾領域52とに異なる斜線を付して示す。後側域S3は、圧搾部が配置される圧搾領域51と、圧搾部が配置されていない非圧搾領域52と、を有する。この圧搾領域51に配置される圧搾部は、吸収コア31と表面シート11を圧縮した圧搾部、すなわち、吸収コア31と表面シート11に設けられた圧搾部であり、本実施の形態では、長手圧搾部82と後側圧搾部84である。
次に、図6を参照し、吸収性物品1の装着操作の一例について説明する。図6は、使用中の吸収性物品1を模式的に示した斜視図である。吸収性物品1を下着等に装着する際は、一般的に、着用者は、着用者の股下に配置される股下域S1を下着に固定し、その後、後側域S3を下着に固定する。より詳細には、着用者は、第1本体粘着部61を下着のクロッチ域に当接させるとともに、第2本体粘着部62をクロッチ域の後方の下着に当接させる。次いで、着用者は、ウイング3を下着の非肌対向面側T2に折り返し、ウイング粘着部63を下着のクロッチ域の非肌対向面に当接させる。また、着用者は、ヒップフラップ粘着部64をクロッチ域の後方の下着に当接させる。
着用者が吸収性物品を装着する際は、吸収性物品を指で挟んだり、指で肌面シートをなぞったりして、吸収性物品を下着側に押し当てる。このとき、指が圧搾部に常に触れていると、着用者は、圧搾部の硬さを常に感じ、吸収性物品に対して柔らかい印象を持ちにくい。
次いで、本願発明に係る表面シートの不織布の性能を確認するため、本発明に係る不織布(実施例)と、本発明の構成を有しない不織布(比較例)とを比較評価する実験を行った。比較評価の実験は、実施例と比較例とについて、不織布の粗滑感を評価するために不織布の表面摩擦や粗さについての表面特性を調べる共に、不織布の硬軟感を評価するために不織布の厚み方向の圧縮特性を調べ、比較した。実施例に係る不織布と比較例に係る不織布は、繊維径が異なる。実施例の不織布は、第1層の繊維径が第2層よりも細い。比較例の不織布は、第1層の繊維径が第2層よりも太い。
