Abstract
Description
第1繊維層2の曲げ剛性値B1と第2繊維層3の曲げ剛性値B2の測定は、カトーテック(株)製KES−FB2−AUTO−A曲げ測定試験機を用いて行った。まず、第1及び2繊維層2,3のそれぞれについて、それらを形成する繊維不織布の所定領域において10cm×10cmにカットしてサンプルとした。次に、各サンプルにおいて伸縮性シートの第1方向Yで測定できるように測定試験機のチャック間に固定する。最大曲率+2.5cm-1まで表側に曲げ、次に、最大曲率−2.5cm-1まで裏側に曲げた後に元に戻すことによって行った。曲げ剛性値B1,B2[N・m2/m×10^−4]は、表側に曲げはじめて曲率に対する曲モーメントの傾きがほぼ一定になったときの傾きと裏側に曲げはじめて曲率に対する曲モーメントの傾きがほぼ一定になったときの傾きとの平均値から算出した。各サンプルにつきN=5測定し、その結果を平均して算出した。
{(第1繊維層2の曲げ剛性値B1×第1繊維層2の質量)/(第1繊維層2の質量+第2繊維層3の質量)}+{(第2繊維層3の曲げ剛性値B2×第2繊維層3の質量)/(第1繊維層2の質量+第2繊維層3の質量)}
伸縮性シート10のギャザーの数は、第1方向Yにおける50mmの長さ寸法×弾性体4のピッチ幅の範囲内における凹部20又は凸部30の数を第1面11又は第2面12側から目視で数え、平均化(N=2)して求めた。後記の従来の伸縮性シート100のギャザー数についても、同様の方法で測定した。
シートの厚さ寸法の測定には、カトーテック(株)製KES−FB3−AUTO−A圧縮試験機を用いた。まず、 伸縮性シート10を10.0cm×10.0cmの大きさに切り出して測定サンプルとし、各シートが収縮した状態で金属平面の試験台に下面側に第2繊維層、上面側(測定面側)に第1繊維層となるように固定する。サンプルの中心を上下に位置する円盤で静かに挟み込み圧縮面積(円盤の面積)約2.0cm2、荷重0.49hpa下における各試料の厚さ寸法T0を測定する。次に、加圧速度50mm/秒で荷重49.03hpa下になるまで測定サンプルを圧縮し、荷重49.03hpa下における厚さ寸法Tmを測定した。また、厚さ寸法T0から厚さ寸法Tmまで圧縮時に要した仕事量[N・m/m2]をWC,厚さ寸法Tmから厚さ寸法T0に復元時に要した仕事量をWC2として、下記の計算式に基づいて圧縮回復率RC[%]を求めた。
RC(%)=WC2/WC×100
第1繊維層2として、質量17.0g/m2のポリエチレン繊維から構成されたスパンボンド繊維不織布、第2繊維層3として、質量17.0g/m2のポリプロピレン繊維から構成されたスパンボンド繊維不織布を使用した。また、複数条の弾性体として、繊度470dtexのポリウレタン糸を用いて、ピッチ9.0mmの条件下で2.5倍に伸長した状態で第1及び第2繊維層間に収縮可能に取り付けた。

第1繊維層として、質量17.0g/m2のポリプロピレン繊維からなるスパンボンド繊維不織布、第2繊維層として、質量17.0g/m2のポリプロピレン繊維からなるスパンボンド繊維不織布を使用した。また、弾性体として、繊度470dtexのポリウレタン糸を用いて、ピッチ5.0mmの条件下で2.5倍に伸長した状態で第1及び第2繊維層間に収縮可能に取り付けた。
まず、各実施例及び各比較例における伸縮性シートを長さ寸法180mm×幅寸法100mmの大きさにカットした。次に、カットしたシートの両端部を互いに接合して、周囲長140cmの環状のサンプルを形成した。次に、環状のサンプルを被験者の前腕に通して30分間装着させた後に取り外し、目視観察によって前腕に付されたギャザー痕のレベルを決定した。測定は、10名の被験者(成人の男性5名、成人の女性5名)を対象として行い、10名の被験者のギャザー痕のレベルを平均化したものを、各実施例及び各比較例のギャザー痕レベルとした。
レベル1・・ギャザー痕はなく、ゴム痕のみが視認できる状態。
レベル2・・ゴム痕から縦に延びるギャザー痕が確認できる状態。
レベル3・・ゴム痕よりもギャザー痕の方が大きく目立ち、ゴム痕を起点とする1〜3mm程度の縦に延びる多数のギャザー痕が確認できる状態
レベル4・・レベル3で確認されたギャザー痕に加えて、弾性体間に5mm以上の縦に延びるギャザー痕も確認できる状態。
レベル5・・レベル4で確認された5mm以上の縦に延びるギャザー痕が所定範囲(200mm×50mm)内に10本以上確認できる状態。
表1に示すとおり、実施例1〜6に係る伸縮性シート10の荷重下の厚さ寸法Tmは1.5mm以下であって、第1及び第2繊維層2,3の平均の曲げ剛性値は、0.022N・m2/m×10^−4以下であり、ギャザー痕レベルは3.0以下である。一方、比較例1〜3に係る伸縮性シートの荷重下の厚さ寸法Tmは1.5mm以上であって、第1及び第2繊維層の平均の曲げ剛性値は、0.03以上であり、ギャザー痕レベルは3.0以上となっている。すなわち、伸縮性シートにおいて、荷重下の厚さ寸法Tm及び第1及び第2繊維層の平均の曲げ剛性値が大きい場合には、ギャザー痕レベルが高くなる傾向があるといえる。
