Description

Verfahren zur Herstellung von nicht gewebten, chlor- und waschbeständigen Flächengebilden bzw. Vliesen Die Herstellung von nicht gewebten oder nicht gewirkten Flächengebilden bzw. Vliesen aus Fasern ist bekannt. Wesentlich ist dabei, daß die einzelnen Fasern genügend aneinander haften, wofür verschiedene Maßnahmen bekannt sind. Eine derselben besteht in der Verwendung von quellbaren Fasern auf Basis von Polyvinylalkohol (PVA) für sich oder zusammen mit anderen üblichen nicht quellbaren Fasern.Process for the production of non-woven, chlorine and wash resistant Flat structures or nonwovens The production of non-woven or non-knitted Flat structures or nonwovens made of fibers are known. It is essential that the individual fibers adhere to one another sufficiently, for which various measures are known are. One of these is the use of swellable fibers based on Polyvinyl alcohol (PVA) on its own or together with other common non-swellable substances Fibers.

Die so hergestellten Flächengebilde bzw. Vliesen sind jedoch nicht koch- und waschbeständig, da sich die PVA-Faser in heißem Wasser auflöst. Um diesen Nachteil zu vermeiden, kann man den PVA-Anteil in Vliesen mit acetalisierend wirkenden Verbindungen in Gegenwart von sauren Stoffen bei erhöhter Temperatur behandeln. Dieses Verfahren ermöglicht zwar die Herstellung von Vliesen, die eine Behandlung mit kochendem Wasser, nicht jedoch mit chlorhaltigen Bleichmitteln aushalten.However, the flat structures or fleeces produced in this way are not Boil and wash resistant, as the PVA fiber dissolves in hot water. To this one To avoid the disadvantage, one can use the PVA content in nonwovens with acetalizing effects Treat compounds in the presence of acidic substances at elevated temperature. This process allows the production of nonwovens that require a treatment withstand boiling water, but not with bleach containing chlorine.

Es wurde gefunden, daß man PVA-Fasern enthaltende Flächengebilde bzw. Vliese sowohl kochecht als auch gegen chemische Chlorbleichmittel beständig machen kann, wenn man den auf beliebige Weise hergestellten, PVA-Fasern enthaltenden Flächengebilden bzw. Vliesen Derivate des Äthylenimins einverleibt, bei denen mindestens zwei Äthyleniminogruppen im Molekül vorhanden sind.It has been found that sheet structures or fabrics containing PVA fibers can be used. Make fleece both boil-proof and resistant to chemical chlorine bleach can, if the sheet-like structure containing PVA fibers is produced in any way or fleece derivatives of ethyleneimine incorporated in which at least two ethyleneimino groups are present in the molecule.

Bei der praktischen Durchführung der vorliegenden Erfindung bereitet man vorzu.gsweise eine 1- bis 100%ige wäßrige Lösung eines Äthyleniminderivates, mit der man das verfestigte PVA-Fasern enthaltende Vlies auf einem Foulard imprägniert, wobei eine Flottenaufnahme von etwa 100% eintritt. Anschließend trocknet man bei etwa 100° C und kondensiert gegebenenfalls dann das im Flächengebilde befindliche Imprägniermittel bei höherer Temperatur, z. B. 150° C. Beispiel 1 Ein Mischfaservlies, bestehend aus 60 Teilen Viskosefasern, 30 Teilen Baumwolle und 10 Teilen wasserlöslicher PVA-Fasern mit einem Quadratmetergewicht von 60 g wird auf einem Foulard mit Wasser so getränkt, daß eine Wasseraufnahme von 200% erfolgt. Anschließend wird dieses Vlies in einem Filzkalander bei 135° C unter leichtem Anpreßdruck getrocknet und verfestigt. Dieses Fasergebilde wird dann wiederum in einem Foulard mit einer Flotte folgender Zusammensetzung bis zur Wasseraufnahme von 100% getränkt. Flottenzusammensetzung: 97% Wasser 30/0 Triäthyleniminotriazin.Prepared in the practice of the present invention one vorzu.gweise a 1 to 100% aqueous solution of an ethylene imine derivative, with which one impregnates the solidified PVA fibers containing fleece on a padder, a liquor pick-up of about 100% occurs. Then you dry at about 100 ° C and then condenses, if necessary, that is located in the sheet-like structure Impregnating agent at a higher temperature, e.g. B. 150 ° C. Example 1 A mixed fiber fleece, Consists of 60 parts of viscose fibers, 30 parts of cotton and 10 parts of water-soluble PVA fibers with a weight per square meter of 60 g is placed on a padder with water soaked in such a way that a water absorption of 200% takes place. Then this Fleece dried in a felt calender at 135 ° C under light pressure and solidified. This fiber structure is then in turn in a padder with a liquor following composition soaked up to 100% water absorption. Fleet composition: 97% water 30/0 triethyleniminotriazine.

Das so getränkte Gebilde wird bei 105° C getrocknet und 11/Z Minuten einer Temperatur von l50° C ausgesetzt, wobei eine Kondensation oder Polymerisation des Imprägniermittels erfolgt. Das erhaltene Vlies ist gegenüber kochendem Wasser und gegenüber einer üblichen Hypochloritbleiche derart beständig, daß auch nach zwanzigmaliger Behandlung keine Schädigung des Flächengebildes zu erkennen ist. Ein vergleichsweise unter gleichen Bedingungen hergestelltes, jedoch nicht anmeldungsgemäß imprägniertes Flächengebilde wird bereits nach 5 Hypochloritwäschen unbrauchbar. Beispiel 2 Ein Mischfaservlies, bestehend aus 95% Viskosezellwolle und 5% wasserlöslichen PVA-Fasern mit einem Quadratmetergewicht von 70 g wird in einem Foulard bis zu einer 250%igen Wasseraufnahme getränkt, anschließend bei 125° C unter leichtem Anpreßdruck getrocknet und verfestigt. Das erhaltene Vlies wird erfindungsgemäß mit einer 40%igen wäßrigen Lösung von Hexamethylen-diäthylenharnstoff getränkt. Anschließend arbeitet man wie unter Beispiel l beschrieben. Die Eigenschaften des Endproduktes in bezug auf Kochechtheit und Chlorbleichbeständigkeit sind dieselben wie unter Beispiel 1 angegeben.The structure so impregnated is dried at 105.degree. C. for 11/2 minutes exposed to a temperature of 150 ° C, causing a condensation or polymerization of the impregnating agent takes place. The obtained fleece is opposite to boiling water and so resistant to normal hypochlorite bleaching that even after After twenty treatments, no damage to the fabric can be seen. A comparatively produced under the same conditions, but not in accordance with the application Impregnated fabric becomes unusable after 5 hypochlorite washes. Example 2 A mixed fiber fleece, consisting of 95% viscose rayon and 5% water-soluble PVA fibers with a square meter weight of 70 g is in a padder up to one 250% water absorption, then soaked at 125 ° C under slight pressure dried and solidified. The fleece obtained is according to the invention with a 40% strength aqueous solution of hexamethylene diethylenurea soaked. Then works as described in example l. The properties of the final product in relation to fastness to boiling and resistance to chlorine bleaching are the same as in the example 1 specified.

Beispiel 3 Ein Mischfaservlies aus 80% wasserlöslicher PVA-Faser, 220% Viskosezellwolle, 30% Polyamidfasern und 400% Wolle wird wie in den vorhergehenden Beispielen verfestigt und anschließend mit einer 4%igen wäßrigen Lösung von Phosphorsäuretriäthylenimid getränkt. Auch hier erhält man hervorragende Koch- und Chlorbeständigkeit.Example 3 A mixed fiber fleece made of 80% water-soluble PVA fiber, 220% viscose rayon, 30% polyamide fibers and 400% wool will like solidified in the previous examples and then with a 4% aqueous Solution of phosphoric acid triethylenimide soaked. Here, too, you get excellent Boil and chlorine resistance.
