Description

再び、図7及び8を参照すると、第1繊維ウエブ81は第2散布ステーション86を通過した後に第1シート61の基材となる第2繊維ウエブ103と合流してニップローラーと回転サクションドラム84とから構成されるプレスステーション87において互いにプレスされる。第2繊維ウエブ103の一方面には、塗布ステーション88においてホットメルト接着剤107が塗布されており、該ホットメルト接着剤107を介して第1繊維ウエブ81と第2繊維ウエブ103とが互いに接合されて、連続積層体108が形成される。連続積層体108は、搬送ロール82c,82dによって機械方向MDへ搬送され、カットロール109とそれに対向配置されたアンビルロール110とから構成されたカットステーション89において切断することによって、複数の吸液層37が形成される。なお、第1散布ステーション85で散布される高吸水性ポリマー粒子60と粒径や吸収速度等が異なるものを第2散布ステーション86において散布することによって、2種類の高吸水性ポリマー粒子60を積層した吸液性コアを成形することもできる。 Referring again to FIGS. 7 and 8, the first fiber web 81 passes through the second spraying station 86 and then merges with the second fiber web 103 which becomes the base material of the first sheet 61, so that the nip roller and the rotary suction drum 84 are combined. Are pressed together at a press station 87 comprising: A hot melt adhesive 107 is applied to one surface of the second fiber web 103 at an application station 88, and the first fiber web 81 and the second fiber web 103 are bonded to each other via the hot melt adhesive 107. Thus, the continuous laminated body 108 is formed. The continuous laminated body 108 is transported in the machine direction MD by the transport rolls 82c and 82d, and is cut at a cut station 89 composed of the cut roll 109 and the anvil roll 110 disposed opposite thereto, thereby a plurality of liquid absorbing layers. 37 is formed. The superabsorbent polymer particles 60 sprayed at the first spraying station 85 are sprayed at the second spraying station 86 with different particle sizes, absorption speeds, etc., so that two kinds of superabsorbent polymer particles 60 are laminated. It is also possible to mold the liquid absorbent core.

<第3実施形態>
図11及び図12を参照して、以下において、第1実施形態と相違する点についてのみ説明すると、本実施形態において、吸液構造体15上には、縦方向Yへ延びる略矩形状の吸収性パッド114が配置されている。吸収性パッド114は、吸液層37よりも僅かに小さい幅寸法及び長さ寸法を有しており、高吸水性ポリマー粒子とフラッフパルプ等の吸水性繊維とを混合して形成された吸液性コア115と、それを被包する各種公知の繊維不織布又はプラスチックシートから形成されたラップシート116とから構成されている。吸収性パッド114は、吸液層37と対向する面の中央部近傍において吸液層37に向かって凸曲する凸曲部117を有し、該凸曲部117が身体側ライナ38を介して間接的に吸液層37の中央凹部70上に位置している。中央凹部70の位置する身体側ライナ38の肌対向面には、縦方向Yへ所与寸法離間して配置された止着部118a,118b,118cが設けられており、止着部118a,118b,118cを介して吸収性パッド114が吸液構造体15に着脱可能に止着されている。吸収性パッド114は、その凸曲部117が吸液層37の中央凹部70に嵌り込んだ状態で止着されているので、吸収性パッド114は、それが平坦な形状を有する場合に比してより安定的に吸液層37に止着され得る。止着部118a,118b,118cは、メカニカルファスナの複数のフックから形成されており、吸収性パッド114のラップシート116が繊維不織布から形成されている場合にはラップシート116に直接止着してもよいし、複数のループを有する、ラップシート116の外面に設けられた被止着部を介して止着してもよい。吸液構造体15が身体側ライナ38を有しない場合には、吸液層37上に位置する止着部118a,118b,118cを介して直接吸液層37に吸収性パッド114を止着してもよい。止着部118a,118b,118cは、吸収性パッド114が安定的に吸液構造体15に固定される限りにおいて、中央に位置する止着部118aのみが配置されていてもよいし、吸収性パッド114の前後端縁間において一連に縦方向Yへ延びていてもよいし、さらに、3つ以上の複数に分割されていてもよい。
<Third Embodiment>
With reference to FIG. 11 and FIG. 12, only points different from the first embodiment will be described below. In this embodiment, a substantially rectangular absorption extending in the longitudinal direction Y on the liquid absorption structure 15. A conductive pad 114 is disposed. The absorbent pad 114 has a width dimension and a length dimension slightly smaller than those of the liquid absorbent layer 37, and is formed by mixing highly water absorbent polymer particles and water absorbent fibers such as fluff pulp. And a wrap sheet 116 formed of various known fiber nonwoven fabrics or plastic sheets that enclose the core. The absorbent pad 114 has a convex curved parts 117 which convexly curved toward the liquid-absorbent layer 37 in the vicinity of the central portion of the surface facing the liquid absorbent layer 37, the convex curved portion 117 through the bodyside liner 38 It is indirectly located on the central recess 70 of the liquid absorption layer 37. The skin facing surface of the body side liner 38 where the central recess 70 is located is provided with fastening portions 118a, 118b, 118c arranged at a given distance in the longitudinal direction Y, and the fastening portions 118a, 118b. , 118c, the absorbent pad 114 is detachably fixed to the liquid absorbing structure 15. Since the absorbent pad 114 is fixed in a state in which the convex portion 117 is fitted in the central concave portion 70 of the liquid absorbing layer 37, the absorbent pad 114 is compared with the case where the absorbent pad 114 has a flat shape. Thus, the liquid absorbing layer 37 can be more stably attached. The fastening portions 118a, 118b, and 118c are formed from a plurality of hooks of mechanical fasteners. When the wrap sheet 116 of the absorbent pad 114 is formed from a fiber nonwoven fabric, Alternatively, it may be fastened via a fastened portion provided on the outer surface of the lap sheet 116 having a plurality of loops. When the liquid absorbing structure 15 does not have the body side liner 38, the absorbent pad 114 is fixed directly to the liquid absorbing layer 37 via the fixing portions 118 a, 118 b, 118 c located on the liquid absorbing layer 37. May be. As long as the absorptive pad 114 is stably fixed to the liquid absorbing structure 15, the affixing portions 118a, 118b, and 118c may be provided with only the affixing portion 118a located at the center. The front and rear edges of the pad 114 may extend in a series in the vertical direction Y, and may be further divided into three or more.
