Description

Filtergewebe, vornehmlich aus Kunstfasergewirke und Filterschläuche aus diesem Gewebe. Filter fabrics, primarily made of synthetic fiber fabrics and filter hoses from this tissue.

Robert J o s t, Klrenthal/Saar, Kreisstrasse 68 Zur Filterung von Gasen-beispielsweise von Luft-wurden bisher Gewebe aus natürlichen, oder aus Kunstfasern verwendet, bei denen die Maschenweite des gezwirnten Fadens die Durchlässigkeit bestimmte. Der Wirkungsgrad dieser Filter war schlecht. Man versuchte daher, durch nachträgliches Aufrauhen des Gewebes die Filterwirkung zu verbessern. Wenn dies teilweise auch gelang, so musste man jedoch als grossen Mangel dabei in Kauf nehmen, dass die Reinigung dieser Filter, was gewöhnlich durch Schütteln erfolgt, dadurch sehr erschwert wurde. Eine Selbstreinigung, d. h. das von Zeit zu Zeit erfolgende Abfallen der Filterrückstände infolge ihres Eigengewichtes entfiel bei derartigen Stoffen vollkommen. Ausserdem waren diese Filtergewebe nur in einer Richtung elastisch, und mussten, da sie in breiten Bahnen gewebt wurden, bei der Verwendung als Filterschläuche an den Längsseiten vernäht werden. Diese Nähte waren jedoch die gefährtesten Verschleissstellen, an denen die Schläuche zuerst zerstört wurden.Robert J ost, Klrenthal / Saar, Kreisstrasse 68 To filter gases - for example air - have been Fabrics made from natural or synthetic fibers are used at where the mesh size of the twisted thread determined the permeability. The efficiency of these filters was poor. Attempts were therefore made to improve the filter effect by subsequently roughening the fabric. Even though this was partially successful, the major shortcoming was that it made cleaning these filters, which is usually done by shaking, very difficult. Self-cleaning, ie the filter residue falling off from time to time as a result of its own weight, was completely eliminated with such materials. In addition, these filter fabrics were only elastic in one direction and, since they were woven in wide strips, had to be sewn on the long sides when used as filter bags. However, these seams were the most vulnerable points of wear and tear, where the hoses were first destroyed.

Die vorliegende Erfindung stellte sich, in Erkenntnis dieser Mängel, die Aufgabe, einen Filter zu entwickeln, der bei grösster Gasdurchlässigkeit eine möglichst grosse Filterwirkung und leichte Reinigungsmöglichkeit gewährleistet. CD CD- Dieses Ziel wurde erreicht durch ein Fertigungsverfahren, bei dem der Filterstoff nicht wie bisher gewebt, sondern gewirkt wird.The present invention, in recognition of these deficiencies, set itself the task of developing a filter which, with the greatest possible gas permeability, had the greatest possible filter effect and easy cleaning guaranteed. CD CD This goal was achieved through a manufacturing process at where the filter material is not woven as before, but knitted will.

Eine weitere Besonderheit des erfindungsgemässen Filterstoffes besteht darin, dass der Ausgangwerkstoff aus praktisch endlosen, dünnsten Kunststofffasern besteht, die-auch abweichend von den bisher bekannten Verfahren-nicht zu mehreren mitein- ander verzwirnt sind, sondern infolge ihrer Ondulation aneinander haften. Ein derartiger Faden ergibt einen Stoff von fast watteähnlichem Charakter. Die einzelnen Fasern sind dabei von geringer Oberflächenrauhigkeit, so dass sich der Filterstoff sehr leicht reinigen lässt. Dabei ist die Filterwirkung jedoch unvergleichlich besser als bei den bisher aus verzwirnten Fäden hergestellten Stoffen.Another special feature of the filter material according to the invention is that the starting material consists of practically endless, thinnest plastic fibers, which also differ of the previously known methods - not to several with one - are twisted together, but stick to one another as a result of their undulation. Such a thread results in a fabric with an almost wadding-like character. The individual fibers have a low surface roughness, so that the filter material can be cleaned very easily. The filter effect is incomparably better than with the fabrics made from twisted threads up to now.

Ein weiterer Vorteil ist die grössere Wärmebeständigkeit dieses erfindungsgemässen Filterstoffe, welche durch die, die einzelnen Fasern umgebenden Luftpolster gegeben ist, seine durch das Wirken erreichte allseitige Elastizität und vor allem auch die Möglichkeit, die Filterschläuche nahtlos zu fertigen, was ihre Dauerfestigkeit ganz erheblich verbessert.Another advantage is the greater heat resistance of this according to the invention Filter materials, which are given by the air cushions surrounding the individual fibers is, its all-round elasticity achieved through its work and, above all, also the ability to manufacture the filter bags seamlessly, what their fatigue strength improved quite considerably.

Darüberhinaus ist der erfindungsgemässe Filterstoff sowohl beständig gegen chemische Einwirkungen als auch gegen die, den Filterrückständen noch anhaftende Feuchtigkeit, welche die mechanische Festigkeit der bisher bekannten Filter nach verhältnisroässig kurzer Zeit bedeutend herabsetzte.In addition, the filter material according to the invention is both resistant against chemical influences as well as against those still adhering to the filter residues Moisture, which determines the mechanical strength of the previously known filters significantly reduced in a relatively short time.
