Description

Verfahren zum Herstellen von verfestigten bindemittelfreien Vliesstoffen, Zusatzanmeldung zur Patentanmeldung F 424'75 IVc/3k. Die Erfindung bezieht sich auf die Herstellung von verfesti:-ten bindemittelfreien l@adelfilzen, bei denen die Zasern der Polyamidgruppe an den Kreuzungs- und Berünrun";sstellen mikrofein miteinander verbunden sind und bei denen nach der Patentanmeldung F 42 477 IVc/dk die Pol=yamidfasern mit einer ,,Jeichmacherwemulsion oder 'deichmacherlösung benetzt und bei erhöhter Temperatur von 100 - 160 0 0 verklebt werden. Zach einer weiteren Ausgestaltung der Erfindung; werden grobe 1'olyamiafasern verwendet. Nachdem der Nadelfilz mit Polyamidfasern nach dem Verfahren der Hauptanmeldung herestellt ist, wird auf den Nadelfilz nun eine äischun aufgesprüüit, die aus hartbaren Harzen und Füllmitteln besteht. Als hartbare Harze eignen sich besonders Phenole, als Füllmittel eignen sich Kreide,Talkum und ähnliche Stoffe. Je nach dem 7eravendungszweck des &idproduktes können auch Schleifmittel ili der Mischung enthalten sein. Als Schleifmittel eignen sich Korund oder Siliciumcarbid. Durch diesen weiteren Verfahrensgang entsteht ein Produkt, das sich als Scnleifartikel eignet. Es ist im Gegensatz zu den bekannten Schleifartikeln außerordentlich widerstandsfähig.Process for the production of consolidated, binder-free nonwovens, additional application for patent application F 424'75 IVc / 3k. The invention relates to the production of solidified, binder-free, needle-punched felts in which the fibers of the polyamide group are connected to one another in a microfine manner at the intersections and points of intersection and in which, according to patent application F 42 477 IVc / dk, the pile = yamid fibers are wetted with a "Jeichmacherwemulsion or" deichmacherlösung and glued at an elevated temperature of 100-160 0 0. According to a further embodiment of the invention, coarse polyamia fibers are used Polyamide fibers is produced according to the process of the main application, an Äischun is now sprayed onto the needle felt, which consists of hardenable resins and fillers. Phenols are particularly suitable as hardenable resins, while chalk, talc and similar substances are suitable as fillers. Depending on the intended use of the product, abrasives may also be included in the mixture. Corundum or silicon carbide are suitable as abrasives. This further process creates a product that is suitable as an abrasive article. In contrast to the known abrasive articles, it is extremely resistant.

Es ist zwar bekannt, iiarz-Schleifmittelmischungen auf Träger wie Papier, Gewebe oder Vlies aufzutragen. Gezeigt hat sich, daß die Träger Papier und Gewebe, die fast eine geschlossene Oberfläche aufweisen, wenig elastisch sind und den.Schleifstaub nicht in sich aufnehmen können. Dadurch neigen sie zu einem schnelleren Verschleiß. Auch bei einem Schleifartikel, der sich auf einem Trägervlies aufbaut, ist festzustellen, daß die Gebrauchstüchtigkeit (Verschlbiß) noch nicht erhöhten Anforderungen genügt.While it is known to use resin-based abrasive mixes such as To apply paper, fabric or fleece. It has been shown that the carrier paper and Tissues that have an almost closed surface, are not very elastic and cannot absorb the grinding dust. As a result, they tend to be faster Wear and tear. Even with an abrasive article that builds up on a backing fleece, it can be stated that the fitness for use (closure) has not yet increased Requirements are sufficient.

Die Erfindung hat gegenüber den bekannten Schleifartikeln. den Vorteil, durch den strukturellen Aufbau des Nadelfilzes nach der iiauptaru:ieldui;- ) höchsten Auf orderun-en - z.b.
