Abstract

Es wird ein nassfest ausgerüsteter Filter, insbesondere ein Tiefenfilter mit hoher Quellfähigkeit beschrieben, der eine Cellulosefasern-enthaltende, offenporige Hohlräume aufweisende Filtermatrix umfasst, wobei die Cellulosefasern an ihrer Oberfläche chemisch gebundenes Polyisocyanat aufweisen. In einer bevorzugten Ausführungsform enthält die Filtermatrix in ihren Hohlräumen fein verteilte Mikropartikel. Es wird auch ein Verfahren zur Herstellung solcher Filter sowie deren Verwendung in der Nahrungs-, Getränkemittel und pharmazeutischen Industrie beschrieben.
