Title (EN) MELT-BLOWN NONWOVEN FABRIC AND FILTER
(FR) NON-TISSÉ DE FUSION-SOUFFLAGE ET FILTRE
(JA) メルトブローン不織布及びフィルタ
Abstract:
(EN) Provided is a melt-blown nonwoven fabric composed of a propylene-based polymer which, in a discharge curve obtained by gel permeation chromatography, has at least one peak in a position of a molecular weight of 20,000 or more and at least one peak in a position of a molecular weight less than 20,000, and has a limiting viscosity [η] of 0.50-0.75 (dl/g).
(FR) L'invention concerne un non-tissé de fusion-soufflage composé d'un polymère à base de propylène qui, dans une courbe d’étalonnage obtenue par chromatographie sur gel, présente au moins un pic en une position correspondant à une masse moléculaire supérieure ou égale à 20 000 et au moins un pic en une position correspondant à une masse moléculaire inférieure à 20 000, et qui présente une viscosité intrinsèque [η] comprise entre 0,50 et 0,75 (dl/g).
(JA) ゲルパーミエーションクロマトグラフィーにおける排出曲線において、分子量2万以上の位置に少なくとも1つのピークトップと、分子量2万未満の位置に少なくとも1つのピークトップとを有し、極限粘度[η]が0.50(dl/g)~0.75(dl/g)であるプロピレン系重合体からなるメルトブローン不織布。
