Abstract
Description
JIS L1906に準じ、温度20℃、湿度65%の標準状態にサンプルを24時間放置後、幅方向1m×長さ方向1mの試料を採取し、天秤を用いて重量(g)を測定する。得られた重量(g)の小数点以下を四捨五入して目付とした。
剃刀(フェザー安全剃刀(株)製「フェザー剃刃S片刃」)を用いて、サンプルを面に垂直にMD方向に切断し、デジタル顕微鏡[(株)キーエンス(KEYENCE)製デジタルマイクロスコープ(DIGITAL MICROSCOPE) VHX-900]にて試料の断面を観察し厚さを計測した。
目付(g/m2)と厚み(mm)より算出した(不織布の見かけ密度(g/cm3)=目付(g/m2)/厚み(mm)/1000)。
得られた不織布をデジタル顕微鏡((株)キーエンス(KEYENCE)製デジタルマイクロスコープ(DIGITAL MICROSCOPE) VHX-900)にて試料の表面を観察し、縦方向、横方向に関する表面の凹凸の間隔(ピッチ)を測定した。
得られた不織布について、定速伸長形引張試験機(株式会社島津製作所製「AG-IS」)を用いて、JIS L 1913「一般不織布試験方法」の6.3.2に従って、縦方向から45度傾けて裁断し、エタノール50質量%水溶液にて湿潤させた試験片の破断時の引張強さ(N/5cm)、伸度(%)を測定した。試験片が浸漬される水の温度は20℃とした。
得られた不織布について、25cm(MD)×20cm(CD)に裁断した原反にエタノール50質量%水溶液を自重に対して300質量%含浸させたシートを自動化表面試験機(KES-FB4-AUTO-A、カトーテック社製)に設置し、試料張力(400g)、荷重(10g)、表面測定試料移動速度(1mm/sec)で粗さ測定を行なった(加圧下湿潤時表面試験(KFX法))。そこから100mm間に含まれる40μm以上の凹凸の数(表面凹凸数)をカウントした。
JIS L1907 7.2吸水率に準じて測定した。試験片を5cm角に切り出して重量を測定する(Ag)。その試験片を、水に30秒浸した。浸漬後、試験片の一辺をつまんで液から取り出し、1分後の重量(Bg)を測定した。保液率(C%)は下記式
C(%)=[(B-A)/A]×100
にて算出される。
上記の方法により保水したシートを線圧0.1kgf/cmで絞り、シート重量(Dg)を測定し、放出量[(B-D)g]を得た。放出率(E%)は下記式
E(%)=[(B-D)/(B-A)]×100
にて算出される。
JIS L 1913 6.7.3に従い、カンチレバー法によって突き出た長さを測定した。ただし、ウェブの進行に対して45度の方向に裁断し、エタノール50質量%水溶液に300%含浸させたシートを使用した。
(1)サンプルの作製
得られた不織布を、縦(不織布の長手方向)10cm×横(不織布の幅方向)20cmの長方形に切り出し、(ポリエチレンテレフタレート/アルミニウム/ポリプロピレン積層シート)製の袋に入れた。次いで、下記の含浸液を、不織布100重量部に対して含浸液300重量部となるように、上記袋に入れて、不織布に含浸させた。上記袋を密閉して、25℃の雰囲気下に3日間静置して、拭き取りシート(含浸液が含浸された不織布)のサンプルを作製した。
95%エタノール 50.0重量%
イソプロピルメチルフェノール 0.2重量%
l-メントール 0.3重量%
精製水 49.5重量%
合計 100.0重量%

3人の専門評価パネルにより評価を行なった。上記で得られた拭き取りシートのサンプルで、手の甲を3往復拭いて、その際の感触を以下の判定基準で評価した。
5:ゴシゴシとした摩擦感を強く感じた、
4:ゴシゴシとした摩擦感を明確に感じた、
3:ゴシゴシとした摩擦感が僅かにしか感じられなかった、
2:やわらかな摩擦感しか感じられなかった、
1:摩擦感が弱く、滑るような感触であった。
