Verfahren zur Herstellung faserförmiger Flächengebilde Die Erfindung bezieht sich auf ein Verfahren zur Herstellung faserförmiger Flächengebilde, die sich durch hohe Festigkeit und andere wertvolle Gebrauchseigenschaften auszeichen. Das neue Verfahren besteht darin, daß man aus langen Fasern, die unter Verwendung eines Dispergiermittels, bestehend aus den Reaktionsprodukten der gleichzeitigen Einwirkung von Verbindungen mit mindestens einer primären Aminogruppe, Aldehyden und Isonitrilen auf Polyuronsäuren, in einem geeigneten Medium dispergiert sind, in an sich bekannter Weise durch Schöpfen Blächengebilde herstellte, diese trocknet und anschließend mit einer lösung oder Dispersion eines Di- oder Polyisocyanats in einem nichtwässrigen Lösungsmittel behandelt. Es hat sich Uberrasoliend gezeigt, daß auf diese Weite hergestellte Flächengebilde nach Trocknung und erfolgter Aushärtung der reaktionsfähigen Di-oder Polyisocyanate hervorragende Festigkeitseigenschaften zeigen.-Die vor der Behandlung mit den Di- oder Polyisocyanaten nicht wasserfesten Flächengebilde sind nach Einwirkung dieser Reaktionskomponenten auch in Wasser und nichtwässrigen lösungsmitteln selbst bei mechanischer Beanspruchung, wie z.B. Reiben, von hoher Festig-' keit. Sie sind darin den verschweißten Vliesstoffen vergleichbar, zeichnen sich diesen gegenüber aber durch das Fehlen des harten Griffes aus. Method of making fibrous sheet-like structures. The invention relates to a method of making fibrous sheet-like structures that are characterized by high strength and other valuable properties. The new method consists in making long fibers using a dispersant consisting of the reaction products of the simultaneous Action of compounds with at least one primary amino group, aldehydes and isonitriles on polyuronic acids, dispersed in a suitable medium, produced in a known manner by scooping sheet structures, this dries and then with a solution or dispersion of a di- or polyisocyanate treated in a non-aqueous solvent. It has been shown to Uberrasoliend that fabricated to this size after drying and curing the reactive di- or polyisocyanates have excellent strength properties show the prior to treatment with the di- or polyisocyanates, non-water-resistant fabrics are also in water and non-aqueous after the action of these reaction components solvents even with mechanical stress, such as rubbing, of high Strength. They are comparable to the welded nonwovens, draw however, they are distinguished by the lack of a hard grip.

Die hierbei anfallenden Dispergiermittellösungen können als solche ohne weiteres für das erfindungsgemäße Verfahren verwendet werden. Man dispergiert hierzu die Fasern unter Verwendung der Dispergiermittel in üblicher Weise in einer Bütte. Aus der gleichmäßigen Flotte schöpft man dann mittels üblicher Schöpfrahmen Blätter vom gewunschten Flächengewicht, die anschließend getrocknet werden. Die auf diese Weise erhaltenen Blätter zeigen zunächst nur geringe Festigkeit, da eine Faser-zu-Baser-Bindung nicht eingetreten ist. Auch durch eine Überdosis an Dispergiermittel wird keine Besserung erzielt, da zwar die Blätter verleimt, dabei jedoch hart werden. Behandelt man aber die getrockneten Blätter -in erfindungsgemäßer Weise mit der verdünnten nichtwässrigen lösung eines Di- oder Polyisocyanats und läßt anschließend bei Raum- oder erhöhter Temperatur trocknen-und aushärten, so werden die Blätter in hervorragender Weise verfestigt, ohne den textilen Griff zu verlieren. Als Di- oder Bolyisocyanate für diese Stufe des erfindungsgemäßen Verfahrens kommen beispielsweise Phenylendiisocyanat, Tolylendiis ocyanat, Naphthylendiisocyanat, examethylendiisocyanat, Diphenylmethandiisocyanat, Triphenylmethantriisocyanat und dgl. zur Anwendung.The resulting dispersant solutions can be used as such can easily be used for the method according to the invention. Disperse this the fibers using the dispersant in the usual way in a Bucket. From the uniform The fleet is then scooped up by means of the usual Ladle frames leaves of the desired weight per unit area, which are then dried will. The leaves obtained in this way initially show only low strength, since a fiber-to-base bond has not occurred. Also from an overdose there is no improvement in dispersing agent, because although the leaves are glued, but get tough in the process. But if the dried leaves are treated in accordance with the invention Way with the dilute non-aqueous solution of a di- or polyisocyanate and can then dry and harden at room or elevated temperature, so the leaves are solidified in an excellent way without losing the textile handle lose. As di- or bolyisocyanates for this stage of the process according to the invention come for example phenylene diisocyanate, tolylene diisocyanate, naphthylene diisocyanate, example ethylene diisocyanate, diphenylmethane diisocyanate, triphenylmethane triisocyanate and Like. To use.
Bei der erfindungsgemäßen Behandlung der langfaserigen Flächengebilde, deren Einzelfasern noch mit einer dünnen Schicht des Dispergiermittels umhüllt sind, kommt es vermutlich zu einer Reaktion der Hydroxylgruppen an den Kohlenstoffatomen 2 und 3 der glucosidischen Ringe des Polyuronsäureskeletts mit den Di- oder Polyisocyanaten unter Bildung hochvernetzter Polyurethane. Überraschend hat sich gezeigt, daß die auf erfindungsgemäße Weise erhaltenen langfaserigen Flächengebilde neben der ausgezeichneten Festigkeit und dem textilen Griff auch über hervorragende feuchtigkeitsaufsaugende Eigenschaften verfügen, wie sie bei synthetischen Fasern üblicherweise nicht vorhanden sind.In the treatment according to the invention of the long-fiber fabric, whose individual fibers are still coated with a thin layer of the dispersant, there is presumably a reaction of the hydroxyl groups on the carbon atoms 2 and 3 of the glucosidic rings of the polyuronic acid skeleton with the di- or polyisocyanates with the formation of highly networked Polyurethanes. Surprisingly did shown that the long-fiber sheet-like structure obtained in the manner according to the invention In addition to the excellent strength and the textile feel, it is also excellent have moisture-wicking properties, like those found in synthetic fibers usually not present.
