Description
〔1〕 吸水性樹脂及びホットメルト接着剤が、2枚以上の親水性不織布により挟持された構造を有する吸水シート組成物であって、前記親水性不織布の目付量が30g/m2以上、前記吸水性樹脂の含有量が10〜150g/m2、前記ホットメルト接着剤の含有量が、吸水性樹脂の含有量(質量基準)の0.10〜1.0倍である、吸水シート組成物;並びに
〔2〕 前記〔1〕記載の吸水シート組成物を、液体透過性シート及び液体不透過性シートで狭持してなる、吸収性物品、に関する。
吸水性樹脂2.0gを、綿袋(メンブロード60番、横100mm×縦200mm)中に計り取り、500mL容のビーカーに入れた。綿袋に生理食塩水(0.9質量%塩化ナトリウム水溶液、以下同様)500gを一度に注ぎ込み、吸水性樹脂のママコが発生しないように生理食塩水を分散させた。綿袋の上部を輪ゴムで縛り、1時間放置して、吸水性樹脂を十分に膨潤させた。遠心力が167Gとなるよう設定した脱水機(国産遠心機株式会社製、品番:H-122)を用いて綿袋を1分間脱水し、脱水後の膨潤ゲルを含んだ綿袋の質量Wa(g)を測定した。吸水性樹脂を添加せずに同様の操作を行い、綿袋の湿潤時空質量Wb(g)を測定し、次式により吸水性樹脂の生理食塩水保水能を求めた。
吸水性樹脂の生理食塩水保水能(g/g)=[Wa−Wb](g)/吸水性樹脂の質量(g)
本試験は、25℃±1℃に調節された室内で行なった。100mL容のビーカーに、生理食塩水50±0.1gを量りとり、マグネチックスターラーバー(8mmφ×30mmのリング無し)を投入し、ビーカーを恒温水槽に浸漬して、液温を25±0.2℃に調節した。次に、マグネチックスターラー上にビーカーを置いて、回転数600r/minとして、生理食塩水に渦を発生させた後、吸水性樹脂2.0±0.002gを、前記ビーカーに素早く添加し、ストップウォッチを用いて、吸水性樹脂の添加後から液面の渦が収束する時点までの時間(秒)を測定し、吸水性樹脂の吸水速度とした。
吸水性樹脂100gに、滑剤として、0.5gの非晶質シリカ(デグサジャパン(株)、Sipernat 200)を混合した。
(B)JIS標準篩を上から、目開き850μmの篩、目開き600μmの篩、目開き500μmの篩、目開き425μmの篩、目開き300μmの篩、目開き250μmの篩、目開き150μmの篩及び受け皿の順に組み合わせた。
吸水シート組成物を8cm×20cmの短冊形に切断したものを、サンプルとして使用した。
試験液A(低粘性試験液):生理食塩水(0.9質量%塩化ナトリウム水溶液)を、少量の青色1号で着色した。
試験液B(高粘性試験液):10L容の容器に、塩化ナトリウム60g、炭酸ナトリウム(無水物)24g、グリセリン60g及び適量の蒸留水を入れ、完全に溶解した。さらに蒸留水を添加して、水溶液全体の重量を6000gに調整した後、少量の青色1号で着色した。
逆戻り量(g)=Wd−Wc
その後、試験液の拡散長D(cm)を測定した(図3)。
目付量60g/m2のレーヨン繊維とポリエチレンテレフタレート繊維の混合体(レーヨン繊維/ポリエチレンテレフタレート繊維=65/35(質量比))からなる親水性不織布(逆側)の上に、ポリアクリル酸部分中和物(中和度:75モル%)からなる高吸水性樹脂「アクアキープSA60N Type II」(住友精化(株)社製、生理食塩水保水能:40g/g、生理食塩水吸水速度:28秒、質量平均粒径:300μm)とホットメルト接着剤としてエチレン−酢酸ビニル共重合体(溶融温度95℃)とを、それぞれの量がシート面積に対して表1に示す含有量となるように均一に混合した粉末を、均一に散布した。上部から、目付量60g/m2のレーヨン繊維とポリエチレンテレフタレート繊維の混合体(レーヨン繊維/ポリエチレンテレフタレート繊維=65/35(質量比))からなる親水性不織布(順側)を載せた後、加熱圧着によりシート化して、吸水シート組成物を得た。
実施例1において、高吸水性樹脂として、「アクアキープSA60N Type II」の代わりに、「アクアキープ10SH-P」(住友精化(株)社製、生理食塩水保水能:41g/g、生理食塩水吸水速度:4秒、質量平均粒径:160μm)を使用した以外は、実施例1と同じ方法でシート化し、吸水シート組成物を得た。
実施例1において、吸水性樹脂とホットメルト接着剤を散布する不織布(逆側)として、親水性不織布の代わりに、疎水性不織布(目付量40g/m2の疎水性ポリエチレンテレフタレート(100%))を使用した以外は、実施例1と同じ方法でシート化し、吸水シート組成物を得た。
