Abstract
Description
〔1〕 吸水性樹脂及び接着剤を含有してなる吸収層が、不織布により該吸収層の上方及び下方から挟持された構造を有する吸水シート構成体であって、繊維基質により前記吸収層が上下に1次吸収層と2次吸収層とに分割されてなる構造を有し、前記吸水性樹脂の含有量が100〜600g/m2であり、前記接着剤の含有量が吸水性樹脂の含有量(質量基準)に対して0.05〜2.0倍であり、1次吸収層と2次吸収層の吸水性樹脂の合計質量に対する1次吸収層の吸水性樹脂の質量の割合が15%以上50%未満である吸水シート構成体、並びに
〔2〕 前記〔1〕記載の吸水シート構成体が、液体透過性シートと液体不透過性シートの間に挟持されている吸収性物品
に関する。
500mL容のビーカーに、0.9質量%塩化ナトリウム水溶液(生理食塩水)500gを量り取り、600r/minで撹拌させながら、吸水性樹脂2.0gを、ママコが発生しないように分散させる。撹拌させた状態で60分間放置し、吸水性樹脂を十分に膨潤させる。その後、あらかじめ目開き75μm標準篩の質量Wa(g)を測定しておき、これを用いて、前記ビーカーの内容物をろ過し、篩いを水平に対して約30度の傾斜角となるように傾けた状態で、30分間放置することにより余剰の水分をろ別する。膨潤した吸水性樹脂の入った篩いの質量Wb(g)を測定し、以下の式により、吸水性樹脂の生理食塩水吸水能を求める。
吸水性樹脂50gに、滑剤として、0.25gの非晶質シリカ(デグサジャパン(株)、Siperant 200)を混合する。
本明細書において、不織布の親水度は、紙パルプ試験方法No.68(2000)に記載の「はっ水性試験方法」に記載の装置を用いて測定する。
加熱温度を150℃に設定したホットメルト塗工機(株式会社ハリーズ製:マーシャル150)上に、幅15cmのスパンレース不織布(繊維:レーヨン/PET、目付量:35g/m2、厚み:300μm、親水度=38;「不織布A」とする)を敷いた後、接着剤としてスチレン−ブタジエン−スチレンブロック共重合体(SBS;軟化点85℃)を目付量15g/m2で当該不織布上に塗布した。
実施例1において、使用する吸水性樹脂並びに接着剤の含有量を、表1に記載された通りに変更した以外は、実施例1と同様の方法によって吸水シート構成体を得た。
実施例1において、使用する吸水性樹脂並びに接着剤の含有量を、表1に記載された通りに変更した以外は、実施例1と同様の方法によって吸水シート構成体を得た。
ローラー型散布機(株式会社ハシマ製:シンターエースM/C)の投入口に、接着剤としてのエチレン−酢酸ビニル共重合体(EVA;溶融温度95℃)105質量部と、吸水性樹脂350質量部とを均一混合させたものを仕込んだ。一方、ローラー型散布機下部のコンベアーに、幅15cmの不織布Aを敷いた。次いで、散布ローラーと下部コンベアーを稼動させることにより、前記混合物を目付量455g/m2で前記不織布上に均一に積層した。
実施例1において、使用する吸水性樹脂並びに接着剤の含有量を、表1に記載された通りに変更した以外は、実施例1と同様の方法によって吸水シート構成体を得た。
実施例5において、使用する吸水性樹脂並びに接着剤の含有量を、表1に記載された通りに変更した以外は、実施例1と同様の方法によって吸水シート構成体を得た。
実施例5において、使用する吸水性樹脂並びに接着剤の含有量を、表1に記載された通りに変更した以外は、実施例1と同様の方法によって吸水シート構成体を得た。
実施例1において、使用する吸水性樹脂並びに接着剤の含有量を、表1に記載された通りに変更した以外は、実施例1と同様の方法によって吸水シート構成体を得た。
実施例5において、使用する吸水性樹脂並びに接着剤の含有量を、表1に記載された通りに変更した以外は、実施例1と同様の方法によって吸水シート構成体を得た。
実施例5において、使用する吸水性樹脂並びに接着剤の含有量を、表1に記載された通りに変更した以外は、実施例1と同様の方法によって吸水シート構成体を得た。
得られた吸水シート構成体の厚みは、厚み測定器(株式会社尾崎製作所製、型番:J−B)を用いて測定した。測定箇所として、長手方向に左端、中央、右端の3箇所を任意に決め、例えば7.5×20cmの場合、左から5cmを左端、10cmを中央、15cmを右端とする。幅方向は均等な中央部を測定した。
吸水シート構成体の形態保持性は以下の方法によって評価した。
得られた吸水シート構成体を10×10cmの大きさにカットした。次いで2枚の10×10cmアクリル板(質量約60g)の各片面の全面に両面テープを貼り付けた。図3に示すように、アクリル板21、22の対角線が45度を成すように、かつ両面テープが吸水シート構成体23側を向くように上下から挟みこんで、動かないよう圧着した。
B:外観に変化無いが、アクリル板をずらすと、吸水シート構成体中央から剥がれる。
C:吸水シート構成体は中央から2つに分裂し、内容物が散乱する。
吸水シート構成体を7.5×20cmの短冊状で、長手方向が不織布の縦方向(機械方向)となるように切断したものを、サンプルとして使用した。
液体逆戻り量(g)=Wd−Wc(g)
傾斜における漏れ量は、図4に示す装置を用いて行った。
