Title
(EN) FIBER SHEET
(FR) FEUILLE DE FIBRES
(JA) 繊維シート
Abstract
(EN) The present invention provides a fiber sheet comprising fibers that contain an acrylonitrile copolymer, wherein the flexure amount per unit basis weight, evaluated using a predetermined measurement method, is less than 0.44 (unit: mm/g/m2). The fiber sheet according to the present invention is prevented from unintendedly deforming.
(FR) La présente invention concerne une feuille de fibres comprenant des fibres qui contiennent un copolymère d'acrylonitrile, la quantité de flexion par unité de poids de base, évaluée à l'aide d'un procédé de mesure prédéterminé, étant inférieure à 0,44 (unité : mm/g/m2) La feuille de fibres selon la présente invention est empêchée de se déformer de manière non souhaitée.
(JA) 本発明は、アクリロニトリル共重合体を含有した繊維を含んでいる、繊維シートであって、所定の測定方法で評価される、単位目付あたりのたわみ量が０．４４（単位：ｍｍ／ｇ／ｍ２）未満である、繊維シートである。本発明の繊維シートは、意図せず変形するのが防止されている。
