Title (EN) NONWOVEN FABRIC FOR FILTERS AND PROCESS FOR PRODUCTION OF THE SAME
(FR) NON-TISSE DESTINE A DES FILTRES ET SON PROCEDE DE PRODUCTION
(JA) フィルター用不織布およびその製造方法
Abstract: front page image
(EN)The invention provides a nonwoven fabric for filters which is excellent in dust collection performance and exhibits low pressure loss and excellent mechanical characteristics and rigidity; and a process for the production of the nonwoven fabric. A continuous-fiber nonwoven fabric constituted of partially thermocompression-bonded thermoplastic continuous filaments, characterized by having a QF value (Pa-1) of 0.02 to 0.08 and a bending resistance of 2 to 80mN.
(FR)La présente invention concerne un non-tissé destiné à des filtres qui présente d'excellentes capacités de collecte de poussière, une faible perte de pression, d'excellentes caractéristiques mécaniques et une excellente rigidité ; ainsi qu'un procédé permettant de produire le non-tissé. Le non-tissé continu se compose de filaments thermoplastiques continus partiellement liés par thermocompression et se caractérise par une valeur QF comprise entre 0,02 et 0,08 Pa-1 et une résistance à la flexion comprise entre 2 et 80 mN.
(JA) 本発明は、粉塵の捕集性能に優れ、さらに圧力損失が低い上に、機械的特性や剛性に優れるフィルター用不織布およびそのような不織布の製造方法を提供するものである。  本発明のフィルター用不織布は、熱可塑性連続フィラメントからなる部分的に熱圧着された長繊維不織布であって、QF値(Pa-1)が0.02~0.08で、剛軟度が2~80mNであることを特徴とするフィルター用不織布である。
