Abstract

　合成繊維からなる長繊維不織布を用いたことを特徴とする円筒状バグフィルター用不織布であり、前記長繊維不織布が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、目付あたりの円弧状曲げ剛性が０．０５０～１．０００（（ｃＮ／２ｃｍ）／（ｇ／ｍ２））であり、かつ目付あたりの通気量が０．０１０～０．５００（（ｃｃ／ｃｍ２／ｓｅｃ）／（ｇ／ｍ２））であることが好ましい。 　また、円筒状バグフィルター用不織布の製造方法は、熱可塑性重合体を紡糸口金から溶融押し出し後、これをエアサッカーにより牽引、延伸して熱可塑性連続フィラメントとし、これを帯電開繊し移動捕集面上に堆積させて繊維ウェブを形成し、この繊維ウェブをフラットロールにて圧接処理した後に熱エンボスロールにて部分的熱圧着を施すことにより長繊維不織布を形成することである。
