Abstract

To produce milled felting from wool or hair, with embedded additives, non-woven layers of wool fibres are laid conventionally. Metal fibres are added to the laid layers, using noble metals, brass, silver bronze, or German silver. The layers with the metal fibres are combined to a single non-woven and carded. The material is felted and milled, using a fluid for the milling which does not attack the metal fibres, or hardly affects them. The material is finally dried and pressed into a solid or shaped felting body. ADVANTAGE - The metal fibres are firmly embedded in the material, and do not work free even when the felting is under heavy loading

Description

Die Erfindung betrifft ein Verfahren zum Herstellen von gewalktem Filz aus Wolle und in den Filz eingebetteten Zusätzen.The invention relates to a method for producing rolled Felt made of wool and additives embedded in the felt.

Verfestigte Filze werden in der Industrie in vielfältigster Weise benötigt. Dabei bereitet das Einbringen von textilen Zusätzen keinerlei Schwierigkeiten, da sich diese gut mit den Wollfasern des Vlieses beim Krempeln, Filzen und Walken verketten.Solidified felts are used in many different ways in industry needed. The introduction of textile additives prepares no difficulties, as these work well with the wool fibers of the fleece when carding, felting and flexing.

Schwierigkeiten bereitet das Einbringen von festen Zusätzen, die selbst nicht verfilzen und sich mit den Wollfasern nicht ausreichend verketten.Difficulties are the introduction of solid additives, which do not matt themselves and do not bond with the wool fibers chain sufficiently.

Wie die EP 01 78 577 A2 zeigt, ist es bekannt, mittels Vakuum in einen Filzkörper Polier- und Schleifkörner einzubringen. Diese Polier- und Schleifkörner haben eine Korngröße unter 1000 µm und werden daher in dem Filzkörper nicht ausreichend gehalten, so daß sie sich beim Polieren und Schleifen leicht von dem Filz lösen. Mit derartigen Filzkörpern mit eingebetteten Polier- und Schleifkörnern wird daher nur eine vernachlässigbare Verbesserung der Polier- und Schleifleistung erzielt.As EP 01 78 577 A2 shows, it is known to use vacuum insert polishing and abrasive grains into a felt body. These Polishing and abrasive grains have a grain size below 1000 µm and are therefore not kept sufficiently in the felt body, so that they easily come off the felt during polishing and grinding to solve. With such felt bodies with embedded polishing and Abrasive grains are therefore only a negligible improvement of polishing and grinding performance.

Wie die DE-OS 25 12 621 A1 zeigt, ist es auch schon versucht worden, Metallfasern in ein Vlies einzubetten, um eine elektrostatische Abschirmwirkung und eine elektrische Leitfähigkeit zu erzielen. Dabei ließ sich nachweisen, daß während des Krempelns der Fasermasse aus Textilverbundstoffen und Metallfasern etwa 30% der zugefügten Metallfasern in kurze Fasern und Staub zerschnitten wurden und verloren gingen, da sie durch das dünne und leichte Vlies gefallen sind. Aus diesem Grunde wurden die Metallfasern kontinuierlich in Form von Garnen, Gespinsten oder Streifen oder zusammen mit einem garn- oder streifenförmigen Träger der Oberfläche des Vlieses zugeführt.As DE-OS 25 12 621 A1 shows, it has already been tried been to embed metal fibers in a fleece to a electrostatic shielding effect and an electrical  Achieve conductivity. It was shown that while carding the fiber mass from textile composites and metal fibers about 30% of the metal fibers added in short Fibers and dust have been cut and lost since they fell through the thin and light fleece. For this Basically, the metal fibers were continuously in the form of yarn, Woven or stripes or together with a yarn or strip-shaped carrier supplied to the surface of the fleece.

Es ist Aufgabe der Erfindung, einen gewalkten Filz der eingangs erwähnten Art zu schaffen, bei dem Metallfasern ohne Schwierigkeit in den Filz eingebettet und in diesem ausreichend gehalten sind,­ so daß sie sich auch bei Beanspruchung des Filzes nur sehr schwer aus dem Filz lösen.It is an object of the invention, a rolled felt of the beginning to create mentioned type in which metal fibers without difficulty are embedded in the felt and sufficiently held in it, so that it is very difficult even when the felt is stressed detach from the felt.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß aus den Wollfasern in bekannter Weise Vlieslagen gebildet werden, daß auf die Vlieslagen als Zusätze Metallfasern aus Edelmetall, Messing, Silberbronze oder Neusilber aufgebracht werden, daß die mit Metallfasern versehenen Vlieslagen zu einem Vlies mit mehreren Lagen eingebetteter Metallfasern gekrempelt werden, daß das Vlies gefilzt und gewalkt wird, wobei beim Walken eine die Metallfasern nicht oder nur geringfügig angreifende Walkflüssigkeit verwendet wird, und daß aus dem gewalkten Filz mit eingebetteten Metallfasern in bekannter Weise durch Trocknen und Pressen ein Stück- oder Formfilz hergestellt wird.This object is achieved according to the invention in that the wool fibers are formed in a known manner, that on the fleece layers as additives metal fibers made of precious metal, Brass, silver bronze or nickel silver are applied that the nonwoven layers provided with metal fibers to form a nonwoven several layers of embedded metal fibers are carded, that the fleece is felted and tumbled, with one when walking the metal fibers are not or only slightly attacking Milled liquid is used and that from the rolled felt with embedded metal fibers in a known manner by drying and pressing a piece or shaped felt is produced.

Da in vielen Anwendungsfällen des Filzes die magnetische oder elektrische Leitfähigkeit der Zusätze nicht erforderlich ist, wird auf Metalle ausgewichen, die nicht spröde und nichtrostend sind. Durch die Verwendung einer auf die Metalle abgestimmten Walkflüssigkeit wird beim Walken eine chemische Reaktion mit den Metallfasern vermieden. Beim Krempeln werden die Vlieslagen miteinander verbunden, wobei die lose aufgebrachten Metallfasern sich nicht mehr von den Wollfasern, Haaren und dgl. entmischen. Beim Filzen und Walken eines derartig mit Metallfasern vermischten Vlieses werden die Metallfasern fester umschlossen und dementsprechend fester in dem Filz gehalten, auch wenn sie selbst nicht verfilzen.Since in many applications of felt the magnetic or electrical conductivity of the additives is not required is switched to metals that are not brittle and rust-free are. By using a matched to the metals  Whiting liquid becomes a chemical reaction when walking the metal fibers avoided. When carding the fleece layers connected together, the loosely applied metal fibers no longer separate from the wool fibers, hair and the like. When felting and milling one of these mixed with metal fibers The metal fibers are more tightly enclosed and fleece accordingly held more firmly in the felt, even if they themselves do not matt.

Eine einfache Möglichkeit zum Aufbringen der Metallfasern besteht darin, daß die Metallfasern auf die Vlieslagen gestreut werden.There is an easy way to apply the metal fibers in that the metal fibers are sprinkled on the nonwoven layers.

Ist nach einer Ausgestaltung vorgesehen, daß die mit Metallfasern versehenen Vlieslagen auf einer Langpelz- oder Kreuzkrempel gekrempelt werden, dann kann die Ausrichtung der Metallfasern im Filz beeinflußt werden.Is provided according to one embodiment that the with metal fibers provided fleece layers on a long fur or cross card can be carded, then the orientation of the metal fibers be influenced in the felt.

Eine bevorzugte Ausgestaltung ist dadurch gekennzeichnet, daß Metallfasern mit einem Durchmesser von etwa 0,04 bis etwa 0,08 mm und mit einer Länge von etwa 50 bis etwa 70 mm verwendet werden.A preferred embodiment is characterized in that Metal fibers with a diameter of about 0.04 to about 0.08 mm and used with a length of about 50 to about 70 mm will.

Der Anteil der Metallfasern auf den Vlieslagen ist vorzugsweise auf etwa 30% begrenzt.The proportion of metal fibers on the nonwoven layers is preferred limited to about 30%.

Werden Polier- oder Schleiffilze benötigt, dann ist dazu vorgesehen, daß aus dem gepreßten Formfilz mit eingebetteten Metallfasern durch Schleifen und Stanzen oder Drechseln Polier- oder Schleiffilzkörper hergestellt werden.If polishing or sanding felts are required, then this provided that embedded from the pressed molded felt Metal fibers by grinding and punching or turning Polishing or sanding felt bodies can be produced.

Die Erfindung wird anhand von in den Zeichnungen dargestellten Ausführungsbeispielen näher erläutert. Es zeigt: The invention is illustrated in the drawings Embodiments explained in more detail. It shows:

Fig. 2 im Blockschaltbild eine Anlage zum Herstellen eines Stückfilzes nach dem Verfahren der Erfindung. Fig. 2 is a block diagram of a plant for producing a piece felt according to the method of the invention.

Aus Wolle werden in bekannter Weise ein Bett gemacht und durch Wolfen und Krempeln Vlieslagen hergestellt. Wie Fig. 1 zeigt, werden auf die Vlieslagen Metallfasern aufgestreut. Diese Metallfasern sind aus Edelmetall, Messing, Silberbronze, Neusilber oder einem anderen elastischen, nichtrostenden Metall. Die Metallfasern haben einen Durchmesser von etwa 0,04 mm bis etwa 0,08 mm und sind etwa 50 bis etwa 70 mm lang. Die Konzentration der Metallfasern wird bis etwa 20% zugelassen. Die mit Metallfasern beladenen Vlieslagen werden in einer Langpelz- oder Kreuzkrempel zu einem Vlies gekrempelt, in das mehrere Lagen von Metallfasern eingebettet sind. Die Ausrichtung der Metallfasern kann daher in allen Lagen in derselben Richtung vorgenommen oder von Lage zu Lage geändert sein.A bed is made from wool in a known manner and nonwoven layers are produced by wolfen and carding. As shown in Fig. 1, metal fibers are sprinkled on the nonwoven layers. These metal fibers are made of precious metal, brass, silver bronze, nickel silver or another elastic, rustproof metal. The metal fibers have a diameter of about 0.04 mm to about 0.08 mm and are about 50 to about 70 mm long. The concentration of the metal fibers is allowed up to about 20%. The fleece layers loaded with metal fibers are carded into a fleece in a long fur or cross card, in which several layers of metal fibers are embedded. The orientation of the metal fibers can therefore be made in the same direction in all layers or changed from layer to layer.

Wie die Fig. 1 und 2 zeigen, kann aus dem so gefertigten Vlies sowohl ein Formfilz als auch ein Stückfilz hergestellt werden.As shown in FIGS . 1 and 2, both a shaped felt and a piece felt can be produced from the nonwoven fabric produced in this way.

Bei der Herstellung eines Formfilzes gelangt das Vlies mit den eingebetteten Metallfasern in bekannter Weise über Stationen "Rupfen" und "Filzen" zur Walkstation. Hier ist nun darauf geachtet, daß die Walkflüssigkeit auf die Metallfasern so abgestimmt ist, daß diese nicht chemisch zersetzt oder angegriffen werden. Dazu eignen sich z. B. organische Säuren.When producing a shaped felt, the fleece comes with the embedded metal fibers in a known manner via stations "Plucking" and "felting" to the walk station. Here is now on it made sure that the whale liquid on the metal fibers so it is agreed that this does not chemically decompose or attack will. For this purpose, z. B. organic acids.

Der gewalkte Filz wird anschließend getrocknet und gepreßt und kann als Block oder Scheibe mit einer Festigkeit bis zu etwa 0,9 g/cm3 und in einer Stärke bis etwa 100 mm zur Verfügung stehen. Aus diesem Formfilz können nach dem Schleifen Polier- oder Schleifkörper gestanzt und gedrechselt werden, wobei die Stanzrichtung so gewählt wird, daß die Metallfasern möglichst senkrecht zur Polier- oder Schleiffläche des Polier- oder Schleifkörpers stehen.The felted felt is then dried and pressed and can be available as a block or disk with a strength of up to about 0.9 g / cm 3 and a thickness of up to about 100 mm. After grinding, polishing or grinding bodies can be punched and turned from this shaped felt, the punching direction being selected so that the metal fibers are as perpendicular as possible to the polishing or grinding surface of the polishing or grinding body.

Wie Fig. 2 zeigt, kann das Vlies mit den eingebetteten Metallfasern über eine Filzstation direkt der Walkstation zugeführt werden. Die Walkflüssigkeit ist wieder entsprechend an die Metallfasern angepaßt, so daß sie beim Walken möglichst wenig angegriffen werden. Über weitere Vorgänge wie Waschen, Färben, Trocknen, Scheren und Pressen kann in bekannter Weise ein Stückfilz hergestellt werden, der in einer Wickelstation aufgewickelt wird.As shown in FIG. 2, the fleece with the embedded metal fibers can be fed directly to the walk station via a felt station. The milling fluid is again adapted accordingly to the metal fibers, so that they are attacked as little as possible during milling. A piece of felt can be produced in a known manner via further processes such as washing, dyeing, drying, shearing and pressing, which is wound up in a winding station.
