Title (EN) MELT-BLOWN NONWOVEN FABRIC AND MANUFACTURING METHOD THEREFOR
(FR) NON-TISSÉ PRODUIT PAR EXTRUSION-SOUFFLAGE ET SON PROCÉDÉ DE FABRICATION
(JA) メルトブローン不織布およびその製造方法
Abstract:
(EN) Provided are: a melt-blown nonwoven fabric comprising a fiber containing a cyclic olefin-based resin; and a melt-blown nonwoven fabric manufacturing method. This melt-blown nonwoven fabric comprises a fiber containing a cyclic olefin-based resin, wherein, of fiber diameter data measured at 100 points selected at random in an SEM image enlarged 1000-fold, when the fiber diameter data is divided into quartiles from smaller data to larger data, the data having fiber diameters greater than that at the third quartile has an average value of not more than 30 μm.
(FR) L'invention concerne : un non-tissé produit par extrusion-soufflage comprenant une fibre contenant une résine à base d'oléfine cyclique ; et un procédé de fabrication de non-tissé produit par extrusion-soufflage. Ce non-tissé produit par extrusion-soufflage comprend une fibre contenant une résine à base d'oléfine cyclique. Dans des données de diamètre de fibre mesurées au niveau de 100 points sélectionnés au hasard dans une image MEB agrandie 1 000 fois, lorsque les données de diamètre de fibre sont divisées en quartiles allant des données les plus petites aux données les plus grandes, les données ayant des diamètres de fibre supérieurs à ceux au niveau du troisième quartile présente une valeur moyenne inférieure ou égale à 30 µm.
(JA) 環状オレフィン系樹脂を含む繊維で構成されるメルトブローン不織布、およびメルトブローン不織布の製造方法を提供する。前記メルトブローン不織布は、環状オレフィン系樹脂を含む繊維で構成されるメルトブローン不織布であって、1000倍に拡大したSEM画像においてランダムに選択した100ポイントの繊維径データのうち、繊維径の小さいデータから大きなデータへ向かってデータを四分位に分けて得られる第3四分位数より大きな繊維径を有するデータの平均値が30μm以下である。
