Description
表面に空隙を有する伸縮性多孔質フィルムであって、
王研式透気度計により測定される透気度が99999sec/100cc未満であり、
100%伸長した状態での王研式透気度計により測定される透気度が60000sec/100cc未満となる伸長方向を有し、
ヒステリシス試験において、幅20mm、チャック間距離30mmから、引張速度50mm/分にてチャック間距離60mmまで引張り、1分間保持した後、チャック間距離の引張りをなくしたときの残留歪みが10mm以下となる引張り方向を有する。
本発明の伸縮性多孔質フィルムは、表面に空隙を有する伸縮性多孔質フィルムである。本発明の伸縮性多孔質フィルムは、表面に空隙を有することにより、優れた通気性を有する。
本発明の伸縮性多孔質フィルムを製造する方法としては、本発明の効果を損なわない範囲で、任意の適切な方法を採用し得る。
本発明の伸縮性多孔質フィルムは、本発明の効果を有効に利用できる任意の適切な物品に用いることができる。すなわち、本発明の物品は、本発明の伸縮性多孔質フィルムを含む。このような物品としては、代表的には、例えば、絆創膏などが挙げられる。
透気度は、王研式透気度計(sec/100cc)(旭精工株式会社製、商品名:EG01−7−7MR)を用いて測定した。99999sec/100ccを超えるものについては「通気性無し」と判断した。透気度の測定は、製造したフィルムをそのままの状態(通常状態)と、100%伸長した状態と、2種類の測定を行った。なお、100%伸長した状態の測定については、製造したフィルムが一軸延伸されたフィルムである場合は、該延伸の方向と直交する方向(長手(MD)方向に延伸した場合はCD方向)に伸長した。
図3に示すようなヒステリシス試験を、幅20mmの試験片について、チャック間距離30mmから、引張速度50mm/分にてチャック間距離60mmまで引張り、1分間保持した後、チャック間距離の引張りをなくすまで行い、チャック間距離の引張りをなくしたときの残留歪みを測定した。なお、残留歪みの測定については、製造したフィルムが一軸延伸されたフィルムである場合は、引張り方向を、該延伸の方向と直交する方向(長手(MD)方向に延伸した場合はCD方向)とした。
日本ゼオン株式会社製のクインタック3433Nを100部、ヤスハラケミカル株式会社製のクリアロンM105を50部、ヤスハラケミカル株式会社製のYSレジンTO−Lを150部を混練し、ホットメルト粘着剤(A)を調製した。
評価するフィルムの片面に上記ホットメルト粘着剤(A)をスプレー塗布し、CD方向80mm×長手方向20mmにカットし、指先に巻き付け、24時間後の巻き付け部の皮膚の状態を観察し、下記の基準で評価した。
皮膚が通常と変わらない場合:○
皮膚が白くなっている場合:×
(指関節)
評価するフィルムの片面に上記ホットメルト粘着剤(A)をスプレー塗布し、CD方向80mm×長手方向20mmにカットし、指先の第二関節に巻き付け、該関節を5分間屈曲した後の状態を観察し、下記の基準で評価した。
指とフィルムの間に隙間がない場合:○
フィルムが伸びきって、指とフィルムの間に隙間がある場合:○
(ひじ関節)
評価するフィルムの片面に上記ホットメルト粘着剤(A)をスプレー塗布し、CD方向130mm×長手方向95mmにカットし、ひじに巻き付け、該ひじを5分間屈曲した後の状態を観察し、下記の基準で評価した。
ひじとフィルムの間に隙間がない場合:○
フィルムが伸びきって、ひじとフィルムの間に隙間がある場合:○
