Description
「吸収性物品」とは、身体排泄物を吸収しかつ封じ込める装置を、より具体的には、身体より排泄される様々な排泄物を吸収しかつ封じ込めるための、着用者の身体に接して、又はこれと近接するように配置された装置を指す。吸収性物品には、おむつ、トレーニングパンツ、成人用失禁下着及びパッド、女性用衛生用品、胸パッド、介護用マット、涎掛け、創傷包帯用品などが挙げられ得る。本明細書で使用するとき、用語「排出物」には、尿、血液、膣排泄物、母乳、汗、及び糞便が挙げられるが、これらに限定されない。
背景技術で述べたように、一般に、ポリエチレン繊維は、ポリプロピレン繊維よりもツルツルした感触を有する傾向がある。ポリエチレン繊維はまた、より柔軟であり、機械的(引張り)強度が低い傾向がある。したがって、ツルツルした絹のような肌触りをウェブに付与するために、ポリエチレン繊維から形成された表面層を有するウェブを形成することが望ましい場合がある。しかしながら、そのような層は、例えば、着用中の使い捨ておむつの外側カバーにおいて見ることができるように、擦れ摩耗によってほころび易い及びピリングし易い(繊維の絡み合った小さな玉又は筒状のものを形成し易い)場合がある。ほころび及びピリングは、低品質であるという消費者の認識を招き、かつ材料の構造的弱体化につながるので、好ましくない場合がある。
