Description

Filtergewebe für Staubabsdieidung aus Luft oder Gasen Es ist eine bisher unerfüllte Forderung der Staubtechnik, Gewebe für Staubfilter zu schaffen, die einerseits bei einem Höchstwert mechanischer Festigkeit die größtmögliche homogene Durchlässigkeit für die zu filtrierenden'Gase ergeben und andererseits das unliebsame Längen, namentlich bei dem im Schlauchform verwendeten Filtergewebe, durch das erfahrungsgemäß ein Teil des Gewebes für die Staubfiltrierung ausfällt, zu vermeiden.Filter fabric for dust separation from air or gases It's one so far unfulfilled requirement of dust technology to create fabric for dust filters on the one hand the greatest possible homogeneous permeability with a maximum value of mechanical strength for the gases to be filtered and, on the other hand, the unpleasant lengths, namely in the case of the filter fabric used in the form of a tube, through which, experience has shown, a Part of the fabric used for dust filtration should be avoided.

Man hat versucht, das Längen des Filtergewebes dadurch zu vermeiden, daß man insbesondere in der Kette des Gewebes Leinengarn, hartgedrehtes Kammgarn oder sogar feinen Draht einwebt. Dadurch entsteht der Nachteil, daß ein nicht unbeträchtlicher Teil des Gewebes für die Staubfiltrierung verlorengeht. Attempts have been made to avoid the length of the filter fabric by that one especially in the warp of the fabric linen yarn, hard-twisted worsted yarn or even fine wire woven into it. This has the disadvantage that a not inconsiderable Part of the fabric for dust filtration is lost.

Wie Versuche ergeben haben, konnte die überraschende Tatsache festgestellt werden, daß Gewebe aus Wammgarnfäden besonders geeignet sind, wenn diese Fäden eine geringere (300/,) Drehung als es den Textilnormen entspricht, aufweisen. Es wurde festgestellt, daß bei der Belastung eines solchen Gewebes von O,I m3 auf I m2 je Minute bis zu 6 m3 auf I m2 je Minute stets ein gleichmäßiger Luftdurchtritt durch das Gewebe stattfindet. Der Luftwiderstand ist ähnlich günstig wie bei bekannten Geweben aus Streichgarnfäden, hat aber diesen gegenüber den großen Vorteil, daß kein Längen der gefertigten Filterschläuche eintritt. As tests have shown, the surprising fact could be established are that woven fabrics made of woolen yarns are particularly suitable if these threads are a have less (300 /,) twist than the textile norms. It was found that when such a tissue is loaded from 0.1 m3 to I m2 each Minute up to 6 m3 per 1 m2 per minute, a constant air flow through the tissue takes place. The air resistance is similar to that of known ones Woven from carded yarn threads, but has the great advantage over them that no lengths of the manufactured filter bags enter.
