前記実施例1と同じ方法で親水性改質コーティング剤を製造するが、下記表1と同じ組成および組成比を有する親水性改質コーティング剤をそれぞれ製造した。
イソプロピルアルコールを親水性改質コーティング剤として準備した。
ジエステル(Di-ester)20重量%および残量のプロピレングリコール化合物を含む溶液を親水性改質コーティング剤として準備した。
シロキサン系親水性改質コーティング剤であるCTFA(Dimethylsiloxane,3-(3-((3-cocoamidopropyl)dimethylammonio)-2-hydroxyprpoxy)propyl groupterminated acetate/CAS 134737-05-6)を親水性改質コーティング剤として準備した。
前記実施例1~7および比較例1~9で製造した親水性改質コーティング剤それぞれに対する粘度およびpHを測定し、その結果を下記表2に示した。
平均直径17μmのポリプロピレン繊維で製造された坪量18gsmのスパンボンド不織布を準備した(東レ先端素材、商品名LIVSEN)。
前記製造例1と同じ方法で親水性改質された不織布を製造するが、実施例1の親水性改質コーティング剤の代わりに実施例2~5および比較例1~9で準備した親水性改質コーティング剤それぞれを使用して親水性に改質された不織布それぞれを製造して、下記表3のように製造例2~7および比較製造例1~11をそれぞれ実施した。
製造例および比較製造例で製造した不織布を10cm×10cm(横×縦)のサイズに切断して、測定試料を準備した。
製造例および比較製造例で製造した不織布を10cm×10cm(横×縦)のサイズに切断して、測定試料を準備した。
前記実験例1によって液体の吸収度を評価した測定試料を利用してWSP 70.8(09)(Standard Test Method for Wetback After Repeated Strike-Through Time)によって前記測定試料の再濡れ性(具体的に、親水性不織布層の再濡れ性)を測定し、その結果を下記表4に示した。具体的に、前記評価例1によって液体の吸収度を評価した測定試料を新しい吸収紙の上に載置した後、0.9重量%NaCl水溶液20mlを前記吸収紙に入れ、前記測定試料に5kgの荷重を加えた後、前記測定試料に逆に再吸収される液体量を測定して、再濡れ性として記録した。
製造例および比較製造例で製造した不織布から試料を採取し、ISO 10993-5(Biological evaluation of medical devices-Part 5:Tests for in-vitro cytotoxicity)の方法でIC50(inhibition concentration 50、コロニー形成阻害濃度)分析を行い、その結果を下記表4に示した。IC50評価結果は、70~100%である場合、非細胞毒性不織布であると評価する。
