Abstract
Description
「吸収性物品」とは、液体物を吸収かつ/又は収容する着用可能デバイスを指し、より詳細には、着用者の身体に対して、又は近接して配置されて、身体から排出される様々な排出物を吸収し、かつ収容するデバイスを指す。吸収性物品としては、おむつ、トレーニングパンツ、成人用失禁下着、女性用衛生用品を挙げることができる。
図3は、1つの例示の連続的な水流交絡繊維性構造体の製造プロセスの、簡略化された概略図を描いたものである。理解されるように、図3のプロセスにより生成される水流交絡繊維性構造体は、図1〜図2の生理用ナプキン10のような各種の吸収性物品他、おむつ、トレーニングパンツ、成人用失禁下着、その他の同種のものを含む他の各種吸収性物品の製造に使用することができる。
坪量が55gsmで、滑らかな表面を持つ、(1)ビスコースレーヨン繊維(1.7dtex、ステープル長さ38mm)約40%と、(2)約1.0%の二酸化チタン(TiO2)を含むポリプロピレン(PP)及びポリエチレン(PE)から形成された二成分繊維(1.7dtex、長さ40mm、PE鞘50重量%、及びPPコア50重量%)約40%と、(3)ポリエチレンテレフタレート(PET)(ステープル長さ40mm)約20%と、からなる均質な配合物である、水流交絡繊維性構造体試料を生成した。特定しない限り、本明細書に記載されている全ての試験は、試験前の2時間にわたって、約23℃±2.2℃(73°F±4°F)の温度、及び50%±4%の相対湿度の条件に置かれた試料に対して実施された。下の表1〜表5に図示されているように、実質的に乾燥した水流交絡繊維性構造体試料の温度を或る一定の温度まで上昇させることが、所望の流体処理特性(表2〜表5)を維持しながら曲げ剛さ(表1)を増加させるように作用した。
