PROBLEM TO BE SOLVED: To provide a nonwoven fabric that has a drape property in addition to low agent-absorbency and high purity.SOLUTION: A fiber contains a cyclic polyolefin resin with a glass transition temperature of 70°C or more and less than 150°C, and has a fineness of 2 dtex or less. The cyclic polyolefin resin may be an addition copolymer of cyclic olefin and α-olefin or a hydrogenated product thereof.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】 低薬剤吸収性および高純粋性に加え、ドレープ性を兼ね備える不織布を提供する。【解決手段】 ガラス転移温度が７０℃以上１５０℃未満の環状ポリオレフィン系樹脂を含む、繊度が２ｄｔｅｘ以下の繊維。また、前記環状ポリオレフィン系樹脂は環状オレフィンとα－オレフィンの付加共重合体又はその水素添加物であってもよい。【選択図】なし
