Beschreibung
Zusammenfassung:	To provide a method for producing inorganic-fiber mat which facilitates formation even if offcuts are utilized as an inorganic-fiber material.SOLUTION: A method for producing an inorganic-fiber mat using a first inorganic-fiber molded object, which is derived from a needle mat containing an adhered organic binder, comprises: a fibrillation step in which the first inorganic-fiber molded object is fibrillated to obtain inorganic fibers; and a sheet formation step in which slurry containing the fibrillated inorganic fibers is used for sheet formation of an inorganic-fiber mat.SELECTED DRAWING: None 【課題】無機繊維材料に端材を利用する場合であっても、より成形が容易な無機繊維マットの製造方法を提供すること。【解決手段】有機バインダが添着されたニードルマット由来の第一の無機繊維成形体を用い、上記第一の無機繊維成形体を開繊して無機繊維を得る開繊工程と、開繊された上記無機繊維を含むスラリーを用いて無機繊維マットを抄造成形する抄造成形工程と、を有することを特徴とする無機繊維マットの製造方法。【選択図】なし
