【発明の属する技術分野】
本発明は、下着の股部内側に配設されるパッド部で尿失禁時に尿を吸収する失禁用下着に関し、特に尿を吸収したパッド部から下着表面への滲み出しを防止した失禁用下着に関する。
【０００２】
【従来の技術】
従来、この種の失禁用下着として特開平８−２８０７２６号公報及び特開平１０−６０７０３号公報等に開示されるものがあり、これらを図７及び図８に示す。図７に示す従来の失禁用下着は、パンツ１３０の内部に吊り下げ用生地１２０を介して設けてあり、着用者の肌に直接接する側から順にネット状生地１０３、吸収性生地１０４、消臭吸水性部材１０５、ラミネート生地１０６を適宜形状に裁断し、その周縁をネット状生地１０３の一側縁を除いて撥水性テープ生地１０７で巻回し、この撥水性テープ生地１０７の上を縫着部１２５により縫着一体化して形成してある。このネット状生地１０３の一側縁（上端部）には、開口部１０８を設けて袋状部を形成してあり、この開口部１０８を介して着用者の排尿が通常多量の場合は、市販の吸水性パッド部材或いは紙、不織布、布地等の追加吸収性部材１１０を挿入して使用することができる。
【０００３】
このように、失禁用パンツを着用中に排尿し、尿が吸収性部材等に吸収された際、撥水性テープ生地１０７によい、その周縁から外部に水分が滲み出すのが防止され、且つ吊り下げ用生地１２０を介して失禁用部材が宙吊り状に保持されているので、パンツ自体の身生地を濡らすことがなく、着用感の良好な失禁用パンツが得られるのである。また、ネット状生地１０３の一側縁の開口部１０８を設けて袋状部を形成してあるので、同袋状部内に市販の吸水性パッド部材或いは紙、不織布、布地等の追加吸収性部材１１０を挿入して使用することができ、更に吊り下げ用生地１２０をパンツ側に着脱自在に設けることにより、失禁用部材を容易に新しいものと取り替えることができ、洗濯等も容易に行うことができる。
【０００４】
一方、前記図８に示す従来の他の失禁用下着は、ネット状生地２２５、吸収性生地２２６、消臭吸水性部材２２７及びラミネート生地２２８を順次積層し、これらの積層された生地や部材の周縁を撥水処理加工されたラッパ状の撥水性テープ生地２２１、２２４で巻回し、包囲して失禁用部材２２０を形成し、且つ前記ラミネート生地２２８を身生地側に配置すると共に、失禁用部材２２０前身側及び後身側に周縁を身生地２０７と共に縫着部２３０、２３１により一体的に縫着して構成したことにより、失禁時の尿を完全に吸収すると共に、尿の滲み出しを防止し、良好な着用感が得られる。
【０００５】
【発明が解決しようとする課題】
従来の失禁用下着は以上のように各々構成されていたことから、従来前者の場合、失禁用部材が吸収性生地１０４を縫着部１２５により吊り下げ用生地１２０を介して、又は直接にパンツ１３０自体に滲み出すという課題を有する。
また、従来後者の場合、吸収性生地２２６の周縁を撥水性テープ生地２２１、２２４で巻回して縫着部２３０、２３１で縫着する構成としていることから、この吸収性生地２２６と撥水性テープ生地２２１、２２４との隙間から尿が漏れ出るという課題を有する。
【０００６】
本発明は、前記課題を解消するためになされたもので、失禁による尿を吸水した吸水性パッド部材から尿が滲み出すこと及び漏れ出すことを確実に防止でき、且つ構造が簡略で製造が簡易な失禁用下着を提供することを目的とする。
【０００７】
【課題を解決するための手段】
本発明に係る失禁用下着は、少なくとも吸収性生地及び非透水性シートを積層してなる吸水パッド部が、前記非透水性シートを下着の股部内側に対向させた状態で配設される失禁用下着において、前記吸水パッド部の外周縁近傍における全周に亘って線状又は帯状に、且つ前記吸収性生地側の表面から非透水性シートに達するまで、樹脂材を含浸させ、当該含浸させた線状又は帯状の樹脂材を前記非透水性シートと水密状態に一体固化させて止水部を形成すると共に、吸収性生地と非透水性シートを一体化し、前記吸水パッド部が、前記止水部の外側となる端部で前記下着に取付けられるものである。このように本発明においては、吸水パッド部の外周における吸収性生地に含浸させた樹脂材をこの吸収性生地に積層された非透水性シートと水密状態で一体固化し、この吸水パッド部を下着の股部内側に配設するようにしているので、吸水パッド部の端面から吸水した尿が漏れ出ることを確実に防止できると共に、吸水パッド部を簡易に製造できる。
【０００８】
また、本発明に係る失禁用下着は必要に応じて、吸水パッド部が、前記下着の股部内側に縫着されるものである。このように本発明においては、一体固化された樹脂材の外側における吸水パッド部の端部を下着股部内側に縫着するようにしているので、吸水パッド部の吸収性生地のうち尿を吸水する領域と尿を吸収しない領域とを一体固化した樹脂材で区画し、この尿を吸収しない領域を下着に縫着できることとなり、尿を吸水した吸収性生地から縫着の孔及び糸を介して尿が滲み出ることを確実に防止できる。
【０００９】
また、本発明に係る失禁用下着は必要に応じて、吸水パッド部が、前記下着の股部内側に面ファスナで着脱自在に配設されるものである。このように本発明においては、吸水パッド部を下着股部内側に面ファスナで着脱自在に配設しているので、失禁による尿を吸収した吸水パッド部のみを洗濯できることとなり、スペアの吸水パッド部の利用により利便性を向上させることができる。
【００１０】
また、本発明に係る失禁用下着は必要に応じて、樹脂材が、熱硬化性樹脂であり、加熱状態で加圧して前記非透水性シートと一体化させるものである。このように本発明においては、熱硬化性樹脂を吸収性生地に含浸させ非透水性シートに加熱状態で加圧して一体化させるようにしているので、含浸のための塗布工程及び一体固化のための加熱加圧工程のみで製作できることとなり、簡易且つ迅速に製造できる。
【００１１】
また、本発明に係る失禁用下着は必要に応じて、前記樹脂材が、水性ウレタン樹脂を少なくとも含み、乾燥凝固後耐水性となる水性ウレタン樹脂系接着剤であるものである。このように本発明においては、樹脂材として水性ウレタン樹脂系接着剤を用い、樹脂材を含浸させた後そのまま乾燥、凝固させると止水部が形成されることにより、止水部が加熱状態で加圧して形成されない分、止水部と吸水パッドの他部分との間に段差ができない上、硬くなり過ぎず、着用時に違和感がないことに加え、樹脂材の塗布、含浸後、加熱しつつ加圧を行う手間が省け、作業工程を簡略化できる。さらに、止水部を形成する水性ウレタン樹脂を中心とする樹脂材は有機溶媒等の有害化学物質を含まず、製造過程や製造後において有害化学物質の揮発など周囲環境に対する悪影響が少なく、且つ着用者の皮膚への刺激も少なく、安全である。
【００１２】
また、本発明に係る失禁用下着は必要に応じて、前記樹脂材が、水性ウレタン樹脂を少なくとも重量比で３０％以上７０％以下含むと共に、イソプレンゴムラテックスを２８．８ないし６８．８％、加硫分散体液を０．２ないし１．０％、水溶性顔料を１．０ないし２．０％、及び水を０ないし１０％それぞれ含んでなるものである。このように本発明においては、樹脂材として水性ウレタン樹脂と共にイソプレンゴムラテックスや加硫分散体液等をそれぞれ所定割合で含んだものを用い、水性ウレタン樹脂と共にイソプレンゴムが止水部の主要材質をなすことにより、イソプレンゴムは天然ゴムとほぼ同じ分子構造を有して優れた機械的強度と弾性を備え、着用時の様々な動きや摩擦に耐えて水密性を維持可能である一方で、天然ゴムと異なり不純物を含まず、人体に対しアトピー等の原因となる刺激を与えない。
【００１３】
【発明の実施の形態】
（本発明の第１の実施形態）
以下、本発明の第１の実施形態に係る失禁用下着を図１ないし図４に基づいて説明する。図１は本実施形態に係る失禁用下着の全体構成図、図２は本実施形態に係る失禁用下着の要部拡大図、図３は図２のＡ−Ａ断面図、図４は本実施形態に係る失禁用下着の製造過程説明図である。
【００１４】
前記各図において本実施形態に係る失禁用下着は、ウレタン素材からなる非透水性シート１１、吸収性生地１２及び保護生地１３を積層し、この吸収性生地１２及び保護生地１３の外周縁全周に亘って帯状にウレタン樹脂１４ａを含浸させ、このウレタン樹脂１４ａを加熱状態で加圧することにより止水部１４として非透水性シート１１と一体固化して吸水パッド１を形成し、この吸水パッド１をパンツ２における股部２３の内側に前記非透水性シート１１を対向させて縫着部３により縫着される構成である。
【００１５】
前記非透水性シート１１は、ウレタン素材以外に、非透水性で且つ柔軟性を有するフィルム素材、例えばポリエチレン、ポリプロピレン、ポリスチレン等で形成することもできる。前記吸収性生地１２は、天然繊維又は合成繊維等による不織布、メリヤス生地等の吸水性且つ保水性を有する素材で形成される。この吸収性生地１２には、吸水性且つ保水性の素材に加え、消臭性素材、抗菌性素材を含有させることもできる。この消臭性素材としては、活性炭、消臭成分（ノネナール）等があり、また抗菌性素材としては、亜鉛イオン、銅イオン、銀イオン等を含有する亜鉛化合物、銅化合物、銀化合物がある。
【００１６】
前記保護生地１３は、天然繊維又は合成繊維により編織成されたネット状生地又はエンボス生地で形成される。また、この保護生地１３は、生地表面側から下層の吸収性生地１２側への透水性を大とし、吸収性生地１２側から保護生地１３側への透水性を小とする機能素材により形成することもできる。
前記止水部１４は、ウレタン樹脂１４ａ以外に、熱硬化性樹脂としてメラミン系樹脂、ポリエステル、エポキシ樹脂、フラン樹脂、ポリウレタン等で形成することもできる。また、この止水部１４は、熱硬化性樹脂以外に、前記吸収性生地１２及び保護生地１３に任意の第１の樹脂材を含浸させた後に他の溶液を前記第１の樹脂材に加えることにより固化する形成とすることもできる。
【００１７】
次に前記構成に基づく本実施形態に係る失禁用下着の製造工程及び吸収状態について説明する。まず、パンツ２の股部２３に適合する形状に非透水性シート１１、吸収性生地１２及び保護生地１３を裁断し（図４（Ａ）を参照）、この裁断された吸収性生地１２及び保護生地１３の外周近傍の全周に亘ってウレタン樹脂１４ａを塗布して帯状に含浸させる（図４（Ｂ）を参照）。
このウレタン樹脂１４ａを含浸させた帯状の部分を加熱状態で所定の押圧力Ｐにより非透水性シート１１、吸収性生地１２及び保護生地１３を押圧して（図４（Ｃ）を参照）、このウレタン樹脂１４ａを固化させて止水部１４を形成し、この止水部１４により吸収性生地１２及び保護生地１３が非透水性シート１１と水密状態に一体化して吸水パッド１を形成する。この吸水パッド１をパンツ２の股部２３上に載置し、吸水パッド１の端部と止水部１４との間を縫い合わせて縫着部３により吸水パッド１をパンツ２に取付ける（図４（Ｄ）を参照）。
【００１８】
このように製作された本実施形態に係る失禁用下着は、失禁の際に尿が保護生地１３を介して吸収性生地１２に急速に吸収されて保水されると共に、この保水された尿が外周縁部分の全周に亘って形成される止水部１４により側方外部へ漏れ出及び滲み出ることが防止される。特に、裏面側の吸水パッド１へは非透水性シート１１により完全に防水状態で遮蔽され、この止水部１４の外側で縫着部３により吸水パッド１がパンツ２に固着されていることから縫着部３から吸水パッド１へ尿が滲み出すこともない。
【００１９】
（本発明の第２の実施形態）
本発明の第２の実施形態に係る失禁用下着を図５に基づいて説明する。図５は本実施形態に係る失禁用下着の製造過程説明図である。
前記図５において本実施形態に係る失禁用下着は、前記第１の実施形態同様、吸水パッド１をパンツ２の股部２３内側に縫着して形成される構成であり、異なる点として、吸水パッド１をなす、積層された非透水性シート１１、吸収性生地１２、及び保護生地１３のうち、吸収性生地１２及び保護生地１３の外周縁全周に亘って帯状に含浸される樹脂材として、水性ウレタン樹脂を主成分とする接着剤を用い、この接着剤を加熱状態での加圧を経ずに止水部１４として非透水性シート１１と一体固化させる構成を有するものである。
【００２０】
前記樹脂材は、主成分の水性ウレタン樹脂を少なくとも重量比で３０％以上７０％以下含む一方、残り成分のほとんどを占める割合でイソプレンゴムラテックスを含み、その他、イソプレンゴムラテックスを架橋させるための加硫分散体液や、着色用の水溶性顔料をわずかに含み、また、必要に応じて水を少量添加される液状の接着剤となっており、吸水パッド１への塗布、含浸後、乾燥させて水分を揮発させ、凝固させると、非透水性シート１１と一体化した耐水性の止水部１４となる。
この樹脂材をなす水性ウレタン樹脂以外の上記各成分の配合割合は、重量比でイソプレンゴムラテックスが約３０ないし約７０％、加硫分散体液が０．２ないし１．０％、水溶性顔料が１．０ないし２．０％、及び水が０ないし１０％とされるのが望ましい。
【００２１】
次に、前記構成に基づく本実施形態に係る失禁用下着の製造過程及び尿漏れ防止状態について説明する。まず、前記第１の実施形態同様、パンツ２の股部２３に適合する形状に裁断した非透水性シート１１、吸収性生地１２及び保護生地１３を積層し、この積層状態の吸収性生地１２及び保護生地１３の外周全周について、外周端部から所定寸法内方の位置に前記配合の樹脂材を所定幅の帯状に塗布し、含浸させる（図５（Ｂ）参照）。
【００２２】
樹脂材を含浸させた後、積層状態の各生地を所定温度で一定時間放置して樹脂材を乾燥、凝固させ、耐水性の止水部１４を形成する。樹脂材の主成分をなす水性ウレタン樹脂はイソプレンゴムラテックスに対し約２０分程度で強い膜を形成して接着力を発揮することができ、吸水パッド１製作の作業工程を簡略化できる。
止水部１４の形成により、吸収性生地１２及び保護生地１３が非透水性シート１１と水密に一体化して吸水パッド１を構成することとなる。この吸水パッド１端部をパンツ２に縫着して吸水パッド１をパンツ２と一体化すれば（図５（Ｃ）参照）、失禁用下着として完成する。
【００２３】
こうして得られた失禁用下着においては、一旦吸収された尿は吸水パッド１外周縁部分の全周に亘って形成される止水部１４により側方への漏れ出し及び滲み出しを防止されると共に、外方へも非透水性シート１１により完全に遮断される。吸水パッド１は止水部１４より外周端側でパンツ２に縫着されており、この縫着した縫着部３からパンツ２側へ尿が滲み出すこともない。また、止水部１４は、加熱状態で加圧していないために吸水パッド１の他部分との間に段差ができない上、硬くなり過ぎず、着用時に違和感がない。
【００２４】
止水部１４を形成する水性ウレタン樹脂を中心とする樹脂材は有害化学物質を含まず、製造過程や製造後において有害化学物質の揮発など周囲環境に対する悪影響が少なく、且つ着用者の皮膚への刺激も少なく、安全である。さらに、水性ウレタン樹脂と共に止水部１４を構成するイソプレンゴムは天然ゴムとほぼ同じ分子構造を有して優れた機械的強度（耐引裂き性、耐屈曲性）と弾性を備える一方で、天然ゴムと異なりタンパク質等の不純物を含まず、人体に対しアトピー等の原因となる刺激を与えない。
【００２５】
このように、本実施形態に係る失禁用下着は、樹脂材として水性ウレタン樹脂系接着剤を用い、樹脂材を含浸させた後そのまま乾燥、凝固させると止水部１４が形成されることから、止水部１４が加熱状態で加圧して形成されない分、止水部１４と吸水パッド１の他部分との間に段差ができない上、硬くなり過ぎず、着用時に違和感がなく着用感に優れることに加え、樹脂材の塗布、含浸後、加熱しつつ加圧を行う手間が省け、作業工程を簡略化できる。
【００２６】
（本発明の他の実施形態）
本実施形態に係る失禁用下着は、吸水パッド１をパンツ２に縫着する構成としたが、吸水パッド１のパンツ２内側への取付けを面ファスナ、ボタン等を用いた着脱自在の構造とすることもできる。
前記実施形態に係る失禁用下着は、吸水パッド１の非透水性シート１１に止水部１４を加熱加圧により一体化する構成としたが、非透水性シート１１と吸収性生地１２との間に接着材を塗布することなく、所定の温度に加熱して非透水性シート１１を融着により吸収性生地１２と一体化することもできる。
【００２７】
なお、前記第１の実施形態に係る吸水パッド１を止水部１４の外側と外周端縁の間を縫着部３でパンツ２に縫着係止する構成としたが、前記吸水パッド１の止水部１４上を縫着部３で縫着係止する構成とすることもできる。また、この止水部１４は吸水パッド１の所定内側領域から外周端縁までウレタン樹脂等を含浸させて形成することもできる。
【００２８】
また、前記第１の実施形態に係る失禁用下着において、吸水パッド１の樹脂材含浸部分を幅方向については一様に押圧して平らな止水部１４を得る構成としているが、これに限らず、図６に示すように、樹脂材含浸部分の幅方向で複数押圧状態を異ならせつつプレスし、横断面が凹凸状となる止水部１４を得る構成とすることもできる。
【００２９】
さらに、前記第１及び第２の各実施形態に係る失禁用下着においては、吸水パッド１の吸収性生地１２と保護生地１３をそれぞれ別の生地として非透水性シート１１と共に積層、一体化する構成としているが、これに限らず、吸収性生地１２及び保護生地１３として、各層ごとに性状の異なる複数層構造の編組織を有する一枚の生地を用いる構成とすることもでき、吸収性生地１２や保護生地１３の機能を一枚の生地で実現して吸水パッド１の構造を簡略化でき、製造も容易となる。
【００３０】
【発明の効果】
以上のように本発明によれば、吸水パッド部の外周における吸収性生地に含浸させた樹脂材をこの吸収性生地に積層された非透水性シートと水密状態で一体固化し、この吸水パッド部を下着の股部内側に配設するようにしているので、吸水パッド部の端面から吸水した尿が漏れ出ることを確実に防止できると共に、吸水パッド部を簡易に製造できるという効果を奏する。

BACKGROUND OF THE INVENTION
The present invention relates to an incontinence undergarment that absorbs urine at the time of urinary incontinence at a pad part disposed inside the crotch of the undergarment, and more particularly to an incontinence undergarment that prevents bleeding from the pad part that has absorbed urine to the surface of the undergarment. .
[0002]
[Prior art]
Conventionally, this type of incontinence underwear is disclosed in Japanese Patent Laid-Open No. 8-280726 and Japanese Patent Laid-Open No. 10-60703, and these are shown in FIGS. The conventional incontinence undergarment shown in FIG. 7 is provided in the inside of the pants 130 via the hanging fabric 120, and the net-like fabric 103, the absorbent fabric 104, and the deodorant in order from the side in direct contact with the wearer's skin. The water-absorbing member 105 and the laminate fabric 106 are cut into appropriate shapes, and the periphery thereof is wound around the water-repellent tape fabric 107 except for one side edge of the net-like fabric 103. 125 is formed by sewing and integration. An opening 108 is provided on one side edge (upper end) of the net-like fabric 103 to form a bag-like portion. When the wearer urinates normally through the opening 108, a large amount is commercially available. The water absorbent pad member or additional absorbent member 110 such as paper, non-woven fabric, and fabric can be inserted and used.
[0003]
In this way, when urinating while wearing incontinence pants, when the urine is absorbed by the absorbent member or the like, the water-repellent tape fabric 107 is good for the water-repellent tape fabric 107 to prevent moisture from seeping out from the periphery and hanging. Since the incontinence member is held in a suspended manner via the lowering fabric 120, the incontinence pants having a good wearing feeling can be obtained without wetting the body fabric of the pants itself. Moreover, since the opening part 108 of the one side edge of the net-like cloth 103 is provided to form a bag-like part, a commercially available water-absorbing pad member or an additional absorbent member such as paper, non-woven fabric, and cloth is provided in the bag-like part. 110 can be inserted and used. Further, by providing the hanging fabric 120 detachably on the pants side, the incontinence member can be easily replaced with a new one, and washing can be easily performed. it can.
[0004]
On the other hand, the other conventional incontinence undergarment shown in FIG. 8 has a net-like fabric 225, an absorbent fabric 226, a deodorant water-absorbing member 227, and a laminated fabric 228, which are sequentially laminated. The periphery is wound with trumpet-shaped water-repellent tape fabrics 221 and 224 that have been subjected to water-repellent treatment, and surrounded to form an incontinence member 220, and the laminate fabric 228 is disposed on the body fabric side, and the incontinence member 220 The front and back sides are sewn together with the body cloth 207 and the sewn portions 230 and 231 to integrally absorb the urine at the time of incontinence and prevent the urine from bleeding out. And a good wearing feeling is obtained.
[0005]
[Problems to be solved by the invention]
Since the conventional incontinence underwear has been configured as described above, in the former case, the incontinence member is formed of the absorbent fabric 104 via the sewing portion 125 and the fabric 120 for suspension or directly underpants. 130 has the problem of oozing into itself.
In the latter case, the absorbent fabric 226 is wound around the water-repellent tape fabrics 221 and 224 and sewn at the sewing portions 230 and 231. There is a problem that urine leaks from the gap between the fabrics 221 and 224.
[0006]
The present invention has been made to solve the above problems, and can reliably prevent urine from seeping out and leaking out from the water-absorbing pad member that has absorbed urine due to incontinence, and has a simple structure and is easy to manufacture. The purpose is to provide incontinence underwear.
[0007]
[Means for Solving the Problems]
The incontinence undergarment according to the present invention is an incontinence in which a water absorbent pad portion formed by laminating at least an absorbent fabric and a water-impermeable sheet is disposed in a state where the water-impermeable sheet is opposed to the inside of the crotch portion of the undergarment. In the undergarment, the resin material is impregnated in the form of a line or a strip over the entire circumference in the vicinity of the outer peripheral edge of the water absorbent pad portion , and until the water-impermeable sheet is reached from the surface on the absorbent fabric side. A linear or belt-shaped resin material is solidified integrally with the water-impermeable sheet in a water-tight state to form a water-stop part, and the absorbent fabric and the water-impermeable sheet are integrated. It is attached to the underwear at the end which is the outside of the water part . Thus, in the present invention, the resin material impregnated in the absorbent fabric at the outer periphery of the water absorbent pad portion is solidified integrally with the water-impermeable sheet laminated on the absorbent fabric in a watertight state, and the water absorbent pad portion is attached to the underwear. Since it is arranged inside the crotch portion, it is possible to reliably prevent the urine that has absorbed water from leaking from the end face of the water absorption pad portion, and to easily manufacture the water absorption pad portion.
[0008]
Further, incontinence undergarments according to the present invention, if necessary, the water absorption pad portion is intended to be sewn to the crotch portion inside the front Symbol underwear. Thus, in the present invention, the end of the water absorbing pad portion on the outside of the integrally solidified resin material is sewn to the inside of the underwear crotch portion, so that urine is absorbed in the absorbent fabric of the water absorbing pad portion.

Also, the outer side is completely blocked by the water-impermeable sheet 11. The water absorbing pad 1 is sewn to the pants 2 on the outer peripheral end side from the water stop portion 14, and urine does not ooze out from the sewn sewn portion 3 to the pants 2 side. Moreover, since the water stop part 14 is not pressurized in the heating state, a step cannot be formed between the other parts of the water absorbing pad 1, and the water stop part 14 does not become too hard and does not feel strange when worn.
[0024]
The resin material, mainly water-based urethane resin that forms the water-stopping portion 14, does not contain harmful chemical substances, has little adverse effects on the surrounding environment such as volatilization of harmful chemical substances during the manufacturing process and after manufacturing, and does not affect the skin of the wearer. There is little irritation and it is safe. Further, the isoprene rubber constituting the water stop portion 14 together with the water-based urethane resin has substantially the same molecular structure as natural rubber and has excellent mechanical strength (tear resistance, flex resistance) and elasticity, while natural rubber. Unlike other proteins, it does not contain impurities such as proteins and does not give a stimulus that causes atopy to the human body.
[0025]
Thus, the underwear for incontinence according to the present embodiment uses a water-based urethane resin adhesive as a resin material, and after impregnating the resin material, the water-stopping portion 14 is formed by drying and solidifying as it is, Since the water-stop part 14 is not formed by being pressurized in a heated state, there is no step between the water-stop part 14 and the other part of the water-absorbing pad 1, and it does not become too hard, and there is no sense of incongruity when worn and excellent wear feeling.
