Description
本発明は、生理用ナプキン、パンティライナー（おりものシート）、失禁パッド等の吸収性物品に関する。 The present invention relates to an absorbent article such as a sanitary napkin, a panty liner (cage sheet), and an incontinence pad.
従来の生理用ナプキン等の吸収性物品においては、下着の内側に装着して使用し、その両側方から着用者の大腿部による圧力を受けた時に、必ずしもその中央部が身体の排泄部に密着するようには変形せず、該排泄部とナプキンとの間に隙間が生じ、排泄物の横漏れ及び後漏れを誘発していた。 In a conventional absorbent article such as a sanitary napkin, it is used by attaching it to the inside of the underwear, and when the pressure is applied by the wearer's thigh from both sides, the central part is not necessarily the body excretion part. It did not deform so as to be in close contact, and a gap was formed between the excretory part and the napkin, inducing side leakage and rear leakage of excrement.
吸収性物品の中央部を身体の排泄部に密着させやすくすることで、横漏れや後漏れの防止を図ったものとして、例えば、特許文献１には、平面状のベースの表面に、液体を吸収して保持する吸収要素が設けられた吸収性物品において、前記ベースに補助吸収要素として機能するクッション層を具備させ、前記吸収要素を、前記吸収性物品の縦方向に延びる中心線を境界として左右両側に分かれて設けられた分割吸収要素から構成し、前記分割吸収要素と前記クッション層とが共に圧縮された圧縮部を起点として、個々の前記分割吸収要素が、その内側端部が前記クッション層から離れる方向へ変形可能とした吸収性物品が提案されている。
特許文献１に開示されている吸収性物品は、分割された吸収体（分割吸収要素）の身体形状への密着性が必ずしも充分とは言えず、横漏れや後漏れの不安を完全に解消したものとは言えない。また、分割吸収要素を加工するにあたってその製造工程は煩雑である。 The absorbent article disclosed in Patent Document 1 does not necessarily have sufficient adhesion to the body shape of the divided absorbent body (divided absorbent element), and completely eliminates the fear of side leakage and rear leakage. Not a thing. In addition, the manufacturing process is complicated in processing the divided absorbent element.
従って、本発明の目的は、着用時に、着用者の身体形状に良好にフィットし、防漏性に優れ、比較的簡易な製造工程で製造可能な吸収性物品を提供することにある。 Accordingly, an object of the present invention is to provide an absorbent article that fits well to the wearer's body shape when worn, is excellent in leakage prevention, and can be manufactured by a relatively simple manufacturing process.
本発明は、液透過性の表面シート、液不透過性の裏面シート及び両シート間に介在された液保持性の吸収体を具備する吸収性物品において、前記吸収体は、下層吸収体と、該下層吸収体の肌当接面側に積層された上層吸収体とからなり、前記上層吸収体は、その肌当接面側及び／又は非肌当接面側に、吸収性物品長手方向の一端又は該一端近傍から他端又は該他端近傍に亘って形成された溝を有しており、該溝によって該上層吸収体は分割されずに複数の域に区分されており、前記上層吸収体の肌当接面側に前記溝が形成された場合には、該溝は、該上層吸収体と前記表面シートとが一体的に圧縮されて形成されており、前記下層吸収体の肌当接面側と前記上層吸収体の非肌当接面側とは、少なくともそれぞれの吸収性物品長手方向の両側縁を除く部分が接合固定されていない吸収性物品を提供することにより前記目的を達成したものである。 The present invention relates to an absorbent article comprising a liquid-permeable top sheet, a liquid-impermeable back sheet, and a liquid-retaining absorbent interposed between both sheets, wherein the absorbent comprises a lower layer absorbent, The upper layer absorbent is laminated on the skin contact surface side of the lower layer absorbent, and the upper layer absorbent is disposed on the skin contact surface side and / or the non-skin contact surface side in the longitudinal direction of the absorbent article. One end or a groove formed from the vicinity of the one end to the other end or the vicinity of the other end, and the upper layer absorber is divided into a plurality of regions without being divided by the groove, and the upper layer absorption When the groove is formed on the skin contact surface side of the body, the groove is formed by integrally compressing the upper layer absorbent body and the surface sheet, and the skin contact of the lower layer absorbent body The contact surface side and the non-skin contact surface side of the upper absorbent body are at least both side edges in the longitudinal direction of each absorbent article It is obtained by achieving the above object by a portion except to provide an absorbent article which is not fixedly joined.
本発明の吸収性物品は、特に、吸収体の形態に特徴を有するため、着用時において、その両側方から着用者の大腿部による圧力を受けた際に、該吸収体が身体の排泄部に密着するように変形し、該排泄部と該吸収性物品との間に隙間を生じさせないため、着用者の身体形状に良好にフィットし、装着感に優れ、横漏れ及び後漏れを効果的に防止することができる。また、本発明の吸収性物品は、その吸収体が分割されていないので、分割吸収体を備えた従来の吸収性物品に比して、簡易な製造工程で容易に製造することができる。 Since the absorbent article of the present invention is particularly characterized by the form of the absorbent body, when the absorbent body is subjected to pressure by the wearer's thigh from both sides when worn, the absorbent body is the excretory part of the body. It is deformed so as to be closely attached to the body and does not create a gap between the excretory part and the absorbent article, so that it fits well to the wearer's body shape, has an excellent wearing feeling, and is effective for side leakage and rear leakage. Can be prevented. Moreover, since the absorbent article of this invention is not divided | segmented, it can manufacture easily with a simple manufacturing process compared with the conventional absorbent article provided with the division | segmentation absorber.
以下に、本発明について、その好ましい一実施形態に基づき図面を参照しながら説明する。
第１実施形態の生理用ナプキン１は、図１及び図２に示すように、液透過性の表面シート２、液不透過性の裏面シート３、及びこれら両シート間に介在された液保持性の吸収体４を具備し、実質的に縦長に形成されている。また、このナプキン１の肌当接面側には、吸収体４の長手方向両側部に沿って、一対の立体ギャザー５，５が設けられている。本明細書において、「肌当接面側」とは、各部材の両側（面）のうち、着用時に着用者の肌側に配される側（面）である。また、以下、「非肌当接面側」という語句を使用することがあるが、これは、各部材の両側（面）のうち、着用時に着用者の肌側とは反対側に配される側（面）である。
Hereinafter, the present invention will be described based on a preferred embodiment thereof with reference to the drawings.
As shown in FIGS. 1 and 2, the sanitary napkin 1 according to the first embodiment includes a liquid-permeable top sheet 2, a liquid-impermeable back sheet 3, and a liquid retention property interposed between these two sheets. The absorber 4 is provided and is formed substantially vertically long. A pair of three-dimensional gathers 5, 5 are provided on the skin contact surface side of the napkin 1 along both longitudinal sides of the absorbent body 4. In this specification, the “skin contact surface side” is the side (surface) that is disposed on the skin side of the wearer during wearing, out of both sides (surfaces) of each member. In addition, hereinafter, the phrase “non-skin contact surface side” may be used, but this is arranged on the opposite side to the wearer's skin side when worn, on both sides (surfaces) of each member. Side (surface).
前記生理用ナプキン１は、その着用時に着用者の排泄部に対向する排泄部対向部Ａと、該排泄部対向部Ａの前後に延在する前方部Ｂ及び後方部Ｃとを有する。生理用ナプキン１の着用時には、該前方部Ｂが着用者の前（腹）側に、該後方部Ｃが着用者の後（背）側にそれぞれ配される。 The sanitary napkin 1 has an excretion part facing part A that faces the excretion part of the wearer when worn, and a front part B and a rear part C that extend before and after the excretion part facing part A. When the sanitary napkin 1 is worn, the front part B is arranged on the front (abdomen) side of the wearer, and the rear part C is arranged on the rear (back) side of the wearer.
前記表面シート２は、図１及び図２に示すように、前記吸収体４の肌当接面側の全域を被覆している。前記裏面シート３は、該吸収体４の非肌当接面側の全域を被覆し、更に、該吸収体４のナプキン（吸収性物品）幅方向の両側縁それぞれから外方に延出した部分を有し、この延出部分が、ナプキン１の幅方向両側部それぞれにサイドフラップ６を形成している。該サイドフラップ６は、排泄部対向部Ａの位置において更に外方に延出しており、一対のウイング部６１，６１を形成している。前記裏面シート３及び一対の該ウイング部６１，６１の非肌当接面側には、それぞれ粘着剤が塗布されて、ナプキン１をショーツ等に固定するための固定部（図示せず）が形成されている。
第１実施形態のナプキン１の上述の構成は、従来公知の生理用ナプキンと同様である。
As shown in FIGS. 1 and 2, the top sheet 2 covers the entire area of the absorbent body 4 on the skin contact surface side. The back sheet 3 covers the entire region of the absorbent body 4 on the non-skin contact surface side, and further extends outward from both side edges of the absorbent body 4 in the width direction of the napkin (absorbent article). This extending portion forms side flaps 6 on both sides in the width direction of the napkin 1. The side flap 6 extends further outward at the position of the excretory part facing part A, and forms a pair of wing parts 61 and 61. On the non-skin contact surface side of the back sheet 3 and the pair of wing portions 61, 61, an adhesive is applied to form a fixing portion (not shown) for fixing the napkin 1 to shorts or the like. Has been.
The above-described configuration of the napkin 1 according to the first embodiment is the same as that of a conventionally known sanitary napkin.
以下に、第１実施形態のナプキン１における前記吸収体４について詳述する。前記吸収体４は、図２及び図３に示すように、下層吸収体４１と、該下層吸収体４１の肌当接面側に積層された上層吸収体４２とからなる。両吸収体４１，４２は、何れも、実質的に縦長矩形状の平面視形状をなしており、ナプキン１の前記前方部Ｂから前記後方部Ｃに亘って配されている。 Below, the said absorber 4 in the napkin 1 of 1st Embodiment is explained in full detail. As shown in FIGS. 2 and 3, the absorbent body 4 includes a lower layer absorbent body 41 and an upper layer absorbent body 42 laminated on the skin contact surface side of the lower layer absorbent body 41. Both absorbers 41 and 42 have a substantially rectangular shape in plan view, and are arranged from the front part B to the rear part C of the napkin 1.
第１実施形態においては、前記下層吸収体４１の肌当接面側と前記上層吸収体４２の非肌当接面側とは、図２に示すように、それぞれのナプキン（吸収性物品）長手方向の両側縁で、ヒートシールやホットメルト接着剤などにより接合固定されており、接合固定部４５，４５が形成されている。しかし、該両側縁を除く部分では、下層吸収体４１の肌当接面側と上層吸収体４２の非肌当接面側とは接合固定されていない。該接合固定部４５は、両吸収体４１，４２の全長に亘って連続的に形成してもよく、不連続に形成してもよい。 In 1st Embodiment, as shown in FIG. 2, the skin contact surface side of the said lower layer absorber 41 and the non-skin contact surface side of the said upper layer absorber 42 are each napkin (absorbent article) longitudinally. Bonding and fixing portions 45 and 45 are formed at both side edges of the direction by heat sealing or hot melt adhesive. However, the skin contact surface side of the lower layer absorbent body 41 and the non-skin contact surface side of the upper layer absorbent body 42 are not joined and fixed at the portion excluding the both side edges. The joint fixing portion 45 may be formed continuously over the entire length of the absorbers 41 and 42 or may be formed discontinuously.
また、第１実施形態においては、図３に示すように、前記下層吸収体４１は、排泄部対向部Ａにおけるナプキン長手方向両側部それぞれに、括れ４１ａを有している。一方、前記上層吸収体４２は、そのナプキン長手方向両側部に括れを有していない。このように、前記吸収体４のナプキン長手方向両側部のうち、排泄部対向部Ａにおける下層吸収体４１のナプキン長手方向両側部のみに括れ４１ａを設けることで、該排泄部対向部Ａにおけるナプキン全体の剛性が緩和され、排泄部に対するフィット性が一層高められる。 Moreover, in 1st Embodiment, as shown in FIG. 3, the said lower layer absorber 41 has the constriction 41a in each napkin longitudinal direction both sides in the excretion part opposing part A. As shown in FIG. On the other hand, the upper layer absorbent body 42 does not have a constriction on both sides in the napkin longitudinal direction. Thus, the napkin in the excretion part opposing part A is provided by providing the constriction 41a only on the both side parts in the napkin longitudinal direction of the lower layer absorbent body 41 in the excretion part opposing part A among the both sides in the napkin longitudinal direction of the absorber 4. The overall rigidity is alleviated and the fit to the excretory part is further enhanced.
前記上層吸収体４２は、その肌当接面側及び／又は非肌当接面側に、ナプキン長手方向の一端近傍から他端近傍に亘って形成された溝を１本以上有している。該溝は、後述するように、エンボス加工等の押圧手段を用いて、上層吸収体を押圧・圧縮することで形成されている。 The upper layer absorbent body 42 has one or more grooves formed on the skin contact surface side and / or the non-skin contact surface side from the vicinity of one end in the napkin longitudinal direction to the vicinity of the other end. As will be described later, the groove is formed by pressing and compressing the upper absorbent body using a pressing means such as embossing.
第１実施形態においては、前記溝として、該上層吸収体４２の肌当接面側のナプキン幅方向中央部をナプキン長手方向に沿って縦断する中央溝４３と、該肌当接面側に、該中央溝４３を挟んで対称的に形成された一対の弧状の側溝４４，４４とを有する。そして、上層吸収体４２は、これら３本の溝によって分割されずに複数の域に区分されている。即ち、上層吸収体４２は、排泄部対向部Ａにおいて、中央溝４３を介して隣接する２つの中央部吸収域４２１，４２１と、各該中央吸収域４２１に側溝４４を介して隣接する側部吸収域４２２，４２２との合計４つの域に区分されている。 In the first embodiment, as the groove, on the skin contact surface side, a central groove 43 that vertically cuts the napkin width direction central portion on the skin contact surface side of the upper layer absorbent body 42 along the napkin longitudinal direction, It has a pair of arc-shaped side grooves 44 and 44 formed symmetrically with the central groove 43 in between. The upper-layer absorber 42 is divided into a plurality of regions without being divided by these three grooves. That is, the upper layer absorbent body 42 includes, in the excretory part facing part A, two central part absorption areas 421 and 421 that are adjacent to each other through the central groove 43, and side parts that are adjacent to the respective central absorption areas 421 through the side grooves 44. It is divided into a total of four areas including absorption areas 422 and 422.
また、第１実施形態においては、前記中央溝４３及び前記側溝４４，４４は、図１及び図２に示すように、何れも、前記上層吸収体４２と前記表面シート２とが一体的に圧縮されて形成されている。 Further, in the first embodiment, as shown in FIGS. 1 and 2, the central groove 43 and the side grooves 44, 44 are integrally compressed by the upper absorbent body 42 and the top sheet 2. Has been formed.
前記中央溝４３及び前記側溝４４，４４は、図３に示すように、それぞれのナプキン長手方向の両端部を一致させるように形成されている。これら各溝のナプキン長手方向の一端部と、前記上層吸収体４２のナプキン長手方向の一端（該一端の最外側点を通り且つナプキン幅方向と平行な仮想線）との間の距離ｌ1は、好ましくは３０mm以下である。該距離ｌ1を０mm、即ち、上層吸収体４２のナプキン長手方向の一端から距離を置かずに溝を形成することもできる。該距離ｌ1が長すぎると、上層吸収体４２のナプキン長手方向の長さによっては複数の域に区分される範囲が狭くなり、フィット性及び防漏性の向上効果が充分に得られないおそれがある。 As shown in FIG. 3, the central groove 43 and the side grooves 44, 44 are formed so that both ends in the napkin longitudinal direction coincide with each other. The distance l 1 between one end of each groove in the longitudinal direction of the napkin and one end in the longitudinal direction of the napkin of the upper layer absorber 42 (imaginary line passing through the outermost point of the one end and parallel to the napkin width direction) is Preferably, it is 30 mm or less. The distance l 1 is 0 mm, that is, the groove can be formed without leaving a distance from one end of the upper absorbent body 42 in the longitudinal direction of the napkin. If the distance l 1 is too long, depending on the length of the upper absorbent body 42 in the longitudinal direction of the napkin, the range divided into a plurality of regions may be narrowed, and the effect of improving fit and leakage prevention may not be sufficiently obtained. There is.
排泄部対向部Ａにおける前記中央溝４３と前記側溝４４との間の距離ｌ2は、好ましくは１０〜２０mmである。また、排泄部対向部Ａにおける前記側溝４４と前記上層吸収体４２のナプキン長手方向の側端部と間の距離ｌ3は、好ましくは１５〜３０mmである。 The distance l 2 between the central groove 43 and the side groove 44 in the excretory part facing part A is preferably 10 to 20 mm. Moreover, the distance l 3 between the side groove 44 in the excretory part facing part A and the side end part in the napkin longitudinal direction of the upper layer absorbent body 42 is preferably 15 to 30 mm.
第１実施形態においては、図４に示すように、前記中央溝４３の幅ｗ1は、前記側溝４４の幅ｗ2より狭くなっている。これは、ナプキン１の着用時において、その両側方から着用者の大腿部による圧力を受けた時に、中央溝４３を介して隣接する前記中央部吸収域４２１，４２１が、該中央溝４３を着用者の肌側に向けて突出させ且つ該中央溝４３を折り目として、山折りに折れ曲がり易くなるようにする（図６参照）ため、ひいては、優れた装着感、フィット性及び防漏性を得るためである。 In the first embodiment, as shown in FIG. 4, the width w 1 of the central groove 43 is narrower than the width w 2 of the side groove 44. This is because when the napkin 1 is worn, when the pressure applied by the wearer's thigh is received from both sides, the central absorption areas 421 and 421 adjacent to each other through the central groove 43 cause the central groove 43 to In order to protrude toward the wearer's skin and to be easily folded into a mountain fold with the central groove 43 as a crease (see FIG. 6), an excellent fit, fit, and leakage resistance are obtained. Because.
前記中央溝４３の幅ｗ1は、好ましくは２mm以下である。中央溝４３の幅ｗ1が大きすぎると、ナプキン１の着用時にその両側方から着用者の大腿部による圧力を受けた時に、前記中央部吸収域４２１，４２１が、上記のような山折りとはならず、逆に、該中央溝４３を着用者の肌側と反対側に向けて突出させるように折れ曲がる、いわゆる谷折りとなってしまい、排泄部に対するナプキンの密着性及び防漏性の低下を招くおそれがある。
前記側溝４４の幅ｗ2は、好ましくは１．５〜５mmである。該側溝４４は、従来のこの種のナプキンにおける吸収体上に形成された溝と同様に、防漏溝としても機能するものであり、幅ｗ2が該範囲にあることで、防漏溝としての役割を十分に果たすことができる。
The width w 1 of the central groove 43 is preferably 2 mm or less. If the width w 1 of the central groove 43 is too large, when the napkin 1 is worn, when the pressure from the thighs of the wearer is received from both sides, the central absorption areas 421 and 421 may fold as described above. However, conversely, the center groove 43 is bent so as to protrude toward the side opposite to the wearer's skin side, so-called valley fold, and the adhesiveness and leakproofness of the napkin to the excretory part There is a risk of lowering.
The width w 2 of the side groove 44 is preferably 1.5 to 5 mm. The side groove 44 functions as a leak-proof groove in the same manner as the groove formed on the absorbent body in the conventional napkin of this type, and the width w 2 is within the range. Can fully fulfill its role.
前記中央溝４３及び前記側溝４４，４４それぞれの底壁の厚み〔溝の底部と、上層吸収体における該溝が形成されていない側（面）との間の最短距離〕は、適宜調整することができるが、特に、中央溝４３の底壁ｔ（図４参照）は、出来るだけ厚くすることが、図６に示すような山折りを容易にし、谷折りを防止する点で好ましい。 The thickness of the bottom wall of each of the central groove 43 and the side grooves 44, 44 [the shortest distance between the bottom of the groove and the side (surface) where the groove is not formed in the upper-layer absorber] should be adjusted as appropriate. However, in particular, it is preferable to make the bottom wall t (see FIG. 4) of the central groove 43 as thick as possible in order to facilitate mountain folding as shown in FIG. 6 and to prevent valley folding.
第１実施形態においては、着用者の排泄部に近い部分の吸収能力を更に高める観点から、前記上層吸収体４２における複数の前記域のうち、前記中央溝４３を介して隣接する２つの前記中央部吸収域４２１，４２１の坪量を、それぞれ、他の域（前記側部吸収域４２２，４２２）の坪量よりも大きくしている。中央部吸収域４２１と側部吸収域４２２との坪量比は、（中央部吸収域の坪量）：（側部吸収域の坪量）＝４：１〜３：１の範囲にあることが好ましい。尚、中央部吸収域４２１，４２１同士、及び側部吸収域４２２，４２２同士は、それぞれ同じ坪量になっている。 In the first embodiment, from the viewpoint of further increasing the absorption capacity of the portion close to the excretion part of the wearer, two of the centers adjacent to each other through the central groove 43 among the plurality of regions in the upper layer absorbent body 42. The basis weights of the partial absorption areas 421 and 421 are set larger than the basis weights of the other areas (the side absorption areas 422 and 422), respectively. The basis weight ratio between the central absorption region 421 and the side absorption region 422 is in the range of (basis weight of the central absorption region) :( basis weight of the side absorption region) = 4: 1 to 3: 1. Is preferred. The central absorption areas 421 and 421 and the side absorption areas 422 and 422 have the same basis weight.
前記上層吸収体４２の坪量は、好ましくは３００〜５００ｇ／m2である。前記下層吸収体４１の坪量は、好ましくは５０〜２００である。また、上層吸収体４２で経血等の排泄物を出来るだけ吸収させる観点から、上層吸収体４２の坪量は、下層吸収体４１の坪量より大きいことが好ましい。 The basis weight of the upper layer absorbent body 42 is preferably 300 to 500 g / m 2 . The basis weight of the lower layer absorbent body 41 is preferably 50 to 200. Further, from the viewpoint of absorbing excretion such as menstrual blood as much as possible by the upper layer absorber 42, the basis weight of the upper layer absorber 42 is preferably larger than the basis weight of the lower layer absorber 41.
一対の前記立体ギャザー５，５について説明する。一対の前記立体ギャザー５，５は、尿や便、経血等の移動を阻止して、これらの漏れ出しを防止するものであり、それぞれ、図２に示すように、断面Ｌ字状に形成されており、面状の弾性伸縮部５０と、該弾性伸縮部５０の非肌当接面側に一体的に連接された起立部５１とからなる。該弾性伸縮部５０は、ナプキン長手方向に沿って配された複数本の弾性部材５２を具備しており、該弾性部材５２により立体ギャザー５の長手方向（ナプキン長手方向）に伸縮性を有しており、その肌当接面側（上面）にギャザーが形成されている。斯かる構成により、前記吸収体４の側部において、着用者の排泄部から肌を伝って横方向に流れた経血等の排泄物が、該起立部５１によって堰き止められると共に、該吸収体４によって素早く吸収され、より一層横漏れ防止効果が高くなる。 A pair of the three-dimensional gathers 5 and 5 will be described. The pair of three-dimensional gathers 5 and 5 prevent movement of urine, feces, menstrual blood, and the like to prevent leakage thereof, and each has a L-shaped cross section as shown in FIG. It comprises a planar elastic stretchable part 50 and an upright part 51 integrally connected to the non-skin contact surface side of the elastic stretchable part 50. The elastic stretchable portion 50 includes a plurality of elastic members 52 arranged along the longitudinal direction of the napkin, and has elasticity in the longitudinal direction of the three-dimensional gather 5 (longitudinal direction of the napkin). Gather is formed on the skin contact surface side (upper surface). With such a configuration, excrement such as menstrual blood that has flowed laterally from the wearer's excretory part through the skin is blocked by the standing part 51 at the side part of the absorbent body 4, and the absorber 4 is absorbed quickly, and the side leakage prevention effect is further enhanced.
以下に、第１実施形態のナプキン１の製造方法について、図５を参照しながら説明する。図５は、第１実施形態のナプキン１の製造工程の一部である、吸収層の製造工程の概略説明図である。該吸収層は、前記表面シート２と前記吸収体４（下層吸収体４１及び上層吸収体４２）とから構成されるものである。 Below, the manufacturing method of the napkin 1 of 1st Embodiment is demonstrated, referring FIG. FIG. 5 is a schematic explanatory diagram of the manufacturing process of the absorbent layer, which is a part of the manufacturing process of the napkin 1 of the first embodiment. The absorption layer is composed of the top sheet 2 and the absorber 4 (the lower layer absorber 41 and the upper layer absorber 42).
先ず、ロール状に巻かれた上層台紙１０を繰り出し、繰り出された該上層台紙１０上に、吸水性ポリマーと繊維材料との混合積繊物１１を、一定の間隔を置いて間欠的に供給する。次いで、この混合積繊物１１の搬送に合わせて、ロール状に巻かれた上層吸収紙１２を繰り出し、該混合積繊物１１を被覆するように該上層台紙１０上に重ね合わせる。更に、ロール状に巻かれた長尺表面シート２’を繰り出し、該上層吸収紙１２上に重ね合わせて、積層シートを作製する。 First, the upper layer mount 10 wound in a roll shape is fed out, and the mixed product fiber 11 of the water-absorbing polymer and the fiber material is intermittently supplied on the fed upper layer mount 10 at a predetermined interval. . Next, in accordance with the conveyance of the mixed product 11, the upper layer absorbent paper 12 wound in a roll shape is fed out and overlapped on the upper mount 10 so as to cover the mixed product 11. Further, the long surface sheet 2 ′ wound in a roll shape is fed out and superposed on the upper layer absorbent paper 12 to produce a laminated sheet.
次いで、前記積層シート（前記上層台紙１０、前記混合積繊物１１、前記上層吸収紙１２及び前記長尺表面シート２’を順次積層してなる積層シート）に対して、エンボス装置１３を用いてエンボス加工を行う。該エンボス装置１３は、ロール表面に所定形状の凸部が形成されたエンボスロール１４を具備している。所定の加熱加圧条件の下、該エンボスロール１４で、前記積層シートを、その長尺表面シート２’側から押圧することよって、該長尺表面シート２’並びに上層吸収紙１２及び混合積繊物１１それぞれの該凸部に対応する部分が一体的に圧縮され、前記溝（中央溝４３及び側溝４４，４４）が形成される。こうして、長尺の上層吸収層１５が得られる。 Next, an embossing device 13 is used for the laminated sheet (a laminated sheet obtained by sequentially laminating the upper layer mount 10, the mixed fiber 11, the upper layer absorbent paper 12, and the long surface sheet 2 ′). Perform embossing. The embossing device 13 includes an embossing roll 14 in which convex portions having a predetermined shape are formed on the roll surface. By pressing the laminated sheet from the long surface sheet 2 ′ side with the embossing roll 14 under a predetermined heating and pressing condition, the long surface sheet 2 ′, the upper absorbent paper 12 and the mixed fiber are mixed. The part corresponding to the convex part of each object 11 is integrally compressed to form the groove (the central groove 43 and the side grooves 44, 44). In this way, a long upper absorbent layer 15 is obtained.
前記上層吸収層１５は、その前記上層台紙１０の所定箇所に、塗布装置１６によりホットメルト接着剤が塗布され、次工程へ流される。 The upper absorbent layer 15 is coated with a hot melt adhesive at a predetermined location on the upper mount 10 by a coating device 16 and is then flowed to the next step.
一方、前記上層吸収層１５の製造と並行して、長尺の下層吸収層２５を製造する。該下層吸収層２５の製造は、前記長尺表面シート２’を使用せず、また、エンボス加工を行わない点以外は、上述した上層吸収層１５の製造と同様に行われる。こうして、下層台紙２０、混合積繊物２１及び下層吸収紙２２を順次積層してなる長尺の下層吸収層２５が得られる。 On the other hand, a long lower absorbent layer 25 is produced in parallel with the production of the upper absorbent layer 15. The lower absorbent layer 25 is manufactured in the same manner as the above-described upper absorbent layer 15 except that the long topsheet 2 'is not used and embossing is not performed. In this way, a long lower absorbent layer 25 obtained by sequentially laminating the lower mount 20, the mixed fiber 21 and the lower absorbent paper 22 is obtained.
そして、長尺の前記上層吸収層１５と長尺の前記下層吸収層２５とを、位置合わせを行った後、該上層吸収層１５の前記接着剤塗布面（前記上層台紙１０側）を内方にして重ね合わせ、この重ね合わせ状態のままロール対間１７を通過させて加圧し、該上層吸収層１５と該下層吸収層２５とを接合固定させる。こうして、長尺の吸収層３５（前記下層吸収体４１、前記上層吸収体４２及び前記表面シート２の積層体）が得られる。 And after aligning the long said upper layer absorption layer 15 and the said long lower layer absorption layer 25, the said adhesive agent coating surface (the said upper layer mount 10 side) of this upper layer absorption layer 15 is made inward. Then, the upper absorbent layer 15 and the lower absorbent layer 25 are bonded and fixed by passing through the roll pair 17 and applying pressure in this superposed state. In this way, a long absorbent layer 35 (a laminate of the lower layer absorbent body 41, the upper layer absorbent body 42 and the top sheet 2) is obtained.
この後の工程は、従来の生理用ナプキンの製造工程と同様であり、前記立体ギャザー５，５及び前記裏面シート３並びにその他ナプキン構成部材を所定箇所に配して接合固定し、ナプキンの一単位毎に切断することで、第１実施形態のナプキン１が得られる。 The subsequent process is the same as the manufacturing process of the conventional sanitary napkin, and the three-dimensional gathers 5, 5 and the back sheet 3 and other napkin constituent members are arranged and fixed at predetermined locations, and one unit of the napkin The napkin 1 of 1st Embodiment is obtained by cut | disconnecting for every.
