Description

Filtergewebe aus natürlicher und/oder künstlicher Stapelfaser sowie Faservlies mit elektrisch gut leitenden Metalleinlagen Es ist bekannt, in Filterstoffe für Staubabscheider (Gewebe oder Vliese aus Natur- oder/und Kunstfasern) Metalldrähte mit Erd- oder Masseschluß zur Ableitung der auf den Filterstoffflächen etwa auftretenden elektrostatischen Ladungen einzulagern. Filter fabrics made of natural and / or artificial staple fiber and Fiber fleece with metal inserts with good electrical conductivity It is known to be used in filter fabrics for dust separators (fabric or fleece made of natural and / or synthetic fibers) metal wires with earth or ground fault for the discharge of any occurring on the filter material surfaces store electrostatic charges.

Demgegenüber besteht die Erfindung darin, als Metalleinlagen kurze feine Drahtstückchen zu verwenden, die dem Fasermaterial für das Filtergewebe oder Filtervlies bereits vor dem Verspinnen bzw. In contrast, the invention consists in short metal inserts to use fine pieces of wire, which are the fiber material for the filter fabric or Filter fleece even before spinning or

Verpressen beigemischt sind.Compression are mixed.

Die Dimensionen der zu verwendenden kurzen Drahtstückchen sollen etwa den Längen der für die Herstellung des Filterstoffes vorgesehenen Natur-oder Kunstfasern entsprechen. Sie können durch stapelartiges Zerschneiden von Drahtlitzen, insbesondere Litzen aus V2A-Stahl, Kupferlitzen oder anderen dünnen, leicht biegsamen Metalldrähten, gewonnen werden und bilden bei gleichmäßiger und hinreichend dichter Verteilung im Fasergemisch innerhalb des Filterstoffes ein engmaschiges metallisches Leitersystem, das einerseits sehr elastisch ist und anderseits die statische Elektrizität sehr gut und vollständig ableitet, wodurch das Entstehen unerwünschter Spannungsfelder und zu Funkenüberschlägen neigender Potentiale verhindert wird. The dimensions of the short pieces of wire to be used should approximately the lengths of the natural or intended for the production of the filter material Synthetic fibers correspond. By cutting wire strands in stacks, you can in particular strands made of V2A steel, copper strands or other thin, easily flexible ones Metal wires, are obtained and form when more uniform and sufficiently dense Distribution in the fiber mixture within the filter material is a close-meshed metallic one Conductor system that is very elastic on the one hand and static electricity on the other dissipates very well and completely, which creates undesirable stress fields and potentials that tend to spark over are prevented.
