Description

Verfahren zur Herstellung von Faservliesstoffen Zusatz zur Patentanmeldung F24465VII/8h (Auslegeschrift 1088 016) Durch die Hauptpatentanmeldung ist ein Verfahren zur Herstellung von bindemittelfreien Vliesstoffen geschützt, welches dadurch gekennzeichnet ist, daß ein ganz oder teilweise aus wasseranlösbaren Fasern, vorzugsweise Polyvinylalkoholfasern, bestehendes Fasergemisch kurzzeitig der Einwirkung von Wasser ausgesetzt wird. Dabei wird die Oberfläche der wasseranlösbaren Fasern klebrig und verbindet ,sich so mit anderen Fasern.Process for the production of fiber nonwovens Addendum to patent application F24465VII / 8h (Auslegeschrift 1088 016) The main patent application protects a process for the production of binder-free nonwovens, which is characterized in that a fiber mixture consisting entirely or partially of water-soluble fibers, preferably polyvinyl alcohol fibers, briefly derives Exposure to water. The surface of the water-soluble fibers becomes sticky and connects to other fibers.

Die auf diese Weise erhaltenen Vliese zeichnen sich durch eine Reihe von wertvollen Eigenschaften aus. Nachteilig ist hingegen die Wasserempfindlichkeit der so verfestigten Vliese, die man - wie in der Hauptpatentanmeldung beschrieben - durch eine Nachbehandlung mit Formaldehyd beseitigen kann. Jedoch hat die Verwendung dieses Mittels eine Reihe von Nachteilen. Abgesehen von der Belästigung durch Formaldehyddämpfe, bewirkt die leichte Verdampfbarkeit stetige Schwankungen der Badzusammensetzung.The fleeces obtained in this way are characterized by a number of valuable properties. On the other hand, the water sensitivity is a disadvantage the so consolidated nonwovens, which one - as described in the main patent application - can be eliminated by post-treatment with formaldehyde. However, the use has this means a number of disadvantages. Apart from the nuisance caused by formaldehyde fumes, The easy evaporation causes constant fluctuations in the bath composition.

Es wurde gefunden, daß eine Nachbehandlung wesentlich einfacher und wirksamer mit sehr geringen Mengen eines in der Textilausrüstung an sich bekannten Aminoplastvorkondensats durchgeführt werden kann, z. B. mit Trimethylolmelamin, Tetramethylolacetylendiharnstoff, Dimethyloldioxyäthylenharnstoff, Dimethylolharnstoff USW. It has been found that aftertreatment can be carried out much more easily and effectively with very small amounts of an aminoplast precondensate known per se in textile finishing, e.g. B. with trimethylolmelamine, tetramethylolacetylenediurea, dimethyloldioxyäthylenurea, dimethylolurea etc.

Überraschend ist, daß bereits so geringe Mengen wie 0,1 bis 501, Aminoplastvorkondensat (bezogen auf das Gewicht der im Faservlies anwesenden PVA-Fasern oder anderer wasseranlösbarer Fasern) den angestrebten Effekt hervorrufen. Da die genannten Mengen nicht zur Ausbildung eines vollständigen Schutzüberzuges auf der zu schützenden Faser ausreichen, muß angenommen werden, daß die Aminoplaste, die vorzugsweise zusammen mit Katalysatoren, wie Zinkchlorid oder Ammonchlorid, Verwendung finden, mit der PVA-Faser unter Bildung einer unlöslichen Deckschicht reagieren.It is surprising that even amounts as small as 0.1 to 50 liters of aminoplast precondensate (based on the weight of the PVA fibers or other water-soluble fibers present in the nonwoven fabric) produce the desired effect. Since the amounts mentioned are not sufficient to form a complete protective coating on the fiber to be protected, it must be assumed that the aminoplasts, which are preferably used together with catalysts such as zinc chloride or ammonium chloride, react with the PVA fiber to form an insoluble cover layer .

Beispiel 1 Ein nach Beispie12 der Hauptpatentanmeldung hergestelltes Polyvinylalkoholfasern enthaltendes Faservlies wird in einem Foulard mit einer Tränkflotte behandelt, die 10/, Trimethylolmelamin und 0,10/, Zinkchlorid enthält. Hierauf wird auf 1000/, Feuchtigkeitsgehalt abgequetscht, getrocknet und das eingeführte Kunstharz durch Wärmebehandlung auskondensiert. Dieser Verfestigungsvorgang kann z. B. in einen Düsenkondensationsschrank mit einer Bedüsungstemperatur von z. B. 175° C und einer Raumtemperatur von etwa 150° C ausgeführt werden.EXAMPLE 1 A nonwoven fabric containing polyvinyl alcohol fibers produced according to Example 12 of the main patent application is treated in a padder with an impregnating liquor which contains 10 % trimethylolmelamine and 0.10 % zinc chloride. It is then squeezed off to a moisture content of 1000 %, dried and the synthetic resin introduced is condensed out by heat treatment. This solidification process can e.g. B. in a nozzle condensation cabinet with a nozzle temperature of z. B. 175 ° C and a room temperature of about 150 ° C.

Das Produkt besitzt eine gute Eigenelastizität, hat textilen Griff und kann z. B. in der Bekleidungsindustrie als Versteifungs- und Füllmaterial Verwendung finden. Beispiel 2 Es wird gemäß Beispiel 1 mit der Maßgabe gearbeitet; daß eine Tränkflüssigkeit für das Zwischenprodukt verwendet wird, die 0,250/, Tetramethylolacetylendiharnstoff, 0,05 °/o Ammoniumchlorid und 0,30/, an optischen Aufhellern, z. B. 2 Mol Phenylisocyanat + 1 Mol Diaminostilbenesulfosäure, enthält. Die Weiterbehandlung erfolgt gemäß Beispiel 1. Das so erhaltene Material entspricht dem gemäß Beispiel 1 erhaltenen mit dem Unterschied, daß durch den optischen Aufheller ein weißes Material erhalten wird, das zur Einarbeitung in weiße Damenblusen oder weiße Herrenhemden geeignet ist. Beispiel 3 Es wird gemäß Beispiell verfahren, aber mit der Maßgabe, daß eine Tränkflotte verwendet wird, die 5 °/o Dimethyloldihydroxyäthylenharnstoff und 10/0 Ammonoxalat enthält.The product has good inherent elasticity, has a textile feel and can, for. B. in the clothing industry as a stiffening and filling material use. Example 2 The procedure is as in Example 1 with the proviso; that a soaking liquid is used for the intermediate product, the 0.250 /, tetramethylolacetylenediurea, 0.05 % ammonium chloride and 0.30 /, of optical brighteners, z. B. 2 moles of phenyl isocyanate + 1 mole of diaminostilbenesulfonic acid contains. The further treatment takes place according to Example 1. The material obtained in this way corresponds to that obtained according to Example 1 with the difference that the optical brightener gives a white material which is suitable for incorporation into white women's blouses or white men's shirts. EXAMPLE 3 The procedure is as in the example, but with the proviso that an impregnating liquor is used which contains 5 % dimethyloldihydroxyethylene urea and 10/0 ammonoxalate.

Beispiel 4 Ein Faservlies, bestehend aus 50 Teilen Viskose-Zellwolle, 10 Teilen Polyamidfasern 50/60, 23 Teilen Baumwollkämmlingen, 7 Teilen wasserlöslicher Polyvinylalkoholfasern, wird mit Wasser durchnäßt, indem man es z. B. über einen Saugzylinder führt, der in einem Wasserbad läuft mit einer Temperatur von 40° C.Example 4 A fiber fleece, consisting of 50 parts viscose rayon, 10 parts of polyamide fibers 50/60, 23 parts of cotton noils, 7 parts of water-soluble Polyvinyl alcohol fibers, is soaked with water by z. B. over a Suction cylinder leads, which runs in a water bath with a temperature of 40 ° C.

Nachfolgende Absaugung über eine entsprechende Vorrichtung setzt den Wassergehalt auf etwa 500 °/o, bezogen auf die verwendete Fasermenge, herab. Das durchnäßte Vlies wird in zwei hintereinandergeschalteten Filzkalandern getrocknet und zum Schluß geglättet durch Durchführen durch eine Muldenpresse. Dieses nach dem in der Hauptpatentanmeldung beschriebenen Verfahren hergestellte Faservlies wird in einem Foulard mit einer Tränkflotte, bestehend aus 20/, Trimethylolmelaminvorkondensat, 0,25 °/o Ammoniumchlorid, 3 °/o Ammoniak, mit einem pH-Wert von 10,6 behandelt. Hierauf wird auf 1000/0 Feuchtigkeit abgequetscht.Subsequent suction using a suitable device reduces the water content to about 500%, based on the amount of fiber used. The soaked fleece is dried in two felt calenders connected one behind the other and finally smoothed by passing it through a trough press. This nonwoven fabric produced by the process described in the main patent application is treated in a padder with an impregnating liquor consisting of 20% trimethylolmelamine precondensate, 0.25% ammonium chloride, 3% ammonia, with a pH of 10.6. This is followed by squeezing off moisture to 1000/0.

Dieser Verfestigungsvorgang kann so durchgeführt werden, daß in einem Kondensationsofen das Material 1i/2 Minuten der Einwirkung einer Temperatur von 150° C unterworfen wird.This solidification process can be carried out so that in one Condensation furnace the material 1i / 2 minutes of exposure to a temperature of 150 ° C is subjected.
