Verfahren zum Veredeln von Fasermaterial Es wurde gefunden. daß man Faserrnatürial in technisch erNviiiisclitcr Weise #-erc(lelit kann, wenn man es zunächst mit natürlichen oder synthetischen hochmolekularen organischen Verbindungen, die mehr als zwei mit Isoc\-aiiitgrul)I)eii timsctzungs- fähige o(1,er leicht #-cr#;eifl)are Gruppen besitzen, be- handelt und (Iann einer '\,tclilwl",-iii(llting mit Iso- cvanaten tinlcr\%-irft, (I.,e Z\%-ei Oder mehr Isoc\-anat- grupp-en im Molekül entlialtcn. Für das Verfahren g,-cignetc IS0Cyanate sind beispiefsweisee Ilexaniutli#,1,en#diisoc#-anat, Dcka- 1 meth#lendiisocyanat, Phenvlen- und Toluylen-p-diisocyanat, Diphenylen-p, p'-diisocyanat und die Naphthalindiisocyanate. Als hochmolekulare organische Verbindungen, die mehr als zwei mit Isocyanatgruppen umsetzungsfähige oder unter den Umsützungsbedingungen leicht verseifbare Gruppen besitzen, seien genannt: Dextrin, Stärke, Oxäthylcellulose, Pol3,vinylalkohol, polymere Acrylsäuren, l#lethacrylsäuren oder Alginsäuren so-,vie deren Salze und Ester, Eiweißprodukte, wie Leim oder Kasein, Polyäthyl-eiiimin, Kondensationsprodukte von Formaldehyd mit Harnstoff oder mit Melamin, Superpolyamide so-,vie Kondensationsprodukte aus Polycarbonsäuren und mehrwertIgen d#e noch freie Hy#droxyl- oder CarboxOgruppen enthalten.Process for finishing fiber material It was found. that fiber natural in technically erNviiiisclitcr way # -erc (lelit can if you can do it first with natural or synthetic high molecular weight organic compounds that more than two with Isoc \ -aiiitgrul) I) eii timsctzungs- capable o (1, he easily # -cr #; eifl) are groups, acts and (Iann an '\, tclilwl ", - iii (llting with Iso- cvanaten tinlcr \% - irft, (I., e Z \% - ei or more Isoc \ -anat- groups in the molecule. For the procedure g, -cignetc IS0Cyanate are for example Ilexaniutli #, 1, en # diisoc # -anat, Dcka- 1 methylene diisocyanate, phenylene and toluene-p-diisocyanate, diphenylene-p, p'-diisocyanate and the naphthalene diisocyanates. High molecular weight organic compounds which have more than two groups which can react with isocyanate groups or which can be easily saponified under the conversion conditions include: dextrin, starch, oxethylcellulose, poly, vinyl alcohol, polymeric acrylic acids, methacrylic acids or alginic acids, as well as their salts and esters , Protein products such as glue or casein, polyethylamine, condensation products of formaldehyde with urea or with melamine, super polyamides and many condensation products from polycarboxylic acids and polyvalent ones that still contain free hydroxyl or carboxy groups.

Als Fasermaterial sind für das \',erfahren alle pflanzlichen, tierischen oder künstlichen Fasern sowie daraus hergestellte Waren oder Gewebe, wie Textilien, Leder, Kunstleder oder Papier, geeignet. Ferner kommen Holz oder Fasern aus Kunststoffen aller Art in Betracht.As fiber material for the \ ', all vegetable, animal or artificial fibers as well as goods or fabrics made from them, such as textiles, Leather, synthetic leather or paper, are suitable. Wood or fibers are also made from plastics of all kinds.

Zur Ausführung des Verfahrens wird das Fasermaterial mit Lösungen oder Dispcrsionen der hochmolekularen organischen Verbindungen imprägniert oder überzogen und dann, gewünschtenfalls nach einer Trocknung, in einem zweiten Bad mit einer Lösung von Di- oder Polyisocyanaten nachbehandelt. Die Ware wird schließlich kurze Zeit, im allgemeinen etwa io bis 2o Minuten, auf Temperaturen zwischen etwa ioo und 140' erhitzt. Die Isocyanate können auch in Dampfform angewandt werden. Man kann mit Hilfe des Verfahrens auch gefärbte und ungefärbte Pigmente wasser- und waschecht auf den Stibstraten fixieren.To carry out the process, the fiber material is mixed with solutions or dispersions of the high molecular weight organic compounds or impregnated coated and then, if desired after drying, in a second bath aftertreated with a solution of di- or polyisocyanates. The goods will eventually a short time, generally about 10 to 20 minutes, to temperatures between about ioo and 140 'heated. The isocyanates can also be used in vapor form. With the help of this process, colored and uncolored pigments can also be water- and fix it on the stibstrate, washable.

Es ist bekannt, Textilien wasserabstoßend zu machen, indem man sie mit Gemischen aus organischen Di- oder Polyisocyanaten oder Diisothiocyanaten und solchen organischen Verbindungen behandelt, die mit Isocyanatgruppen umsetzungsfähige Gruppen sowie mindestens sechs: Kohlenstoffatome enthalten. Als derartige Verbindungen sind Alkohole, Amine, Carbonsäuren und Carbonsäureamide aufgezählt, die sich von Fetten, Wachsen, ölen, Harzen oder Naphthensäuren ableiten, sowie aromatische Arnine und Phenole, die Fettreste enthalten,.It is known to make textiles water-repellent by making them with mixtures of organic di- or polyisocyanates or diisothiocyanates and those organic compounds treated that are capable of reacting with isocyanate groups Groups and at least six: contain carbon atoms. As such connections are alcohols, amines, carboxylic acids and carboxamides listed, which differ from Derive fats, waxes, oils, resins or naphthenic acids, as well as aromatic amines and phenols, which contain fatty residues.

Demgegenüber werden die Fasermaterialien beim vorliegenden Verfahren mit hochmolekularen '\,-erbindungen, die mehr als zwei mit Isocvanatgruppen tiinsetzungsf#ihige Gruppen enthalten, #)ehandelt und dann mit Di- oder Polyisocyanateii nachbehandelt. Durch das vorliegende Verfahren wird die Reiß- und die Scheuerfestigkeit des Fasermaterials erheblich stärker verbessert als nach dem bekannten Vcrfahren. Das vorliegende Verfahren, hat gegenüber dem bekannten vor allem den Vorteil, daß die Appreturen äußerst wasser-, wasch- und reibecht sind. auch wenn man Isocvanate und hochmolekulare Verhindungen an-wendet, die an sich nicht hydrophob sind. Nach dem vorliegenden Verfahren veredeltes Zellwollgeweb-- zeigt einen viel geringeren Einsprung als ein nach dem bekannten Verfahren behandeltes.In contrast, the fiber materials in the present process with high molecular weight bonds which can be substituted by more than two with isocvanate groups Contain groups, #) treated and then post-treated with di- or polyisocyanateii. The present process improves the tear resistance and abrasion resistance of the fiber material much more improved than according to the known method. The present proceedings, has the advantage over the well-known that the finishes are extremely water-, are wash and rub fast. even if you have Isocvanate and high molecular weight preventions applies that are not inherently hydrophobic. Refined according to the present process Cellulose tissue - shows a much smaller dent than one after the known Procedure dealt with.

Die in den nachfolgenden Beispielen angegebenen Teile sind Gewicht-steile. Beispiel i 3o Teile Oxäthvlmethylcellulose werden in i ooo Teilen Wasser gelöst; mit dieser Lösung wird Zellwollgewebe imprägniert. Dann wird das Gewebe abgequetscht, bis es nur noch das Doppelte seines Trockengewichtes wiegt, und getrocknet. Das so vorbehan-delte Gewebe wird mit einer Lösung von 34 Teilen Hexamethylendiisoeyanat in iooo Teilen Aceton getränkt und darin 20 Minuten langauf 130' erhitzt. Die so erhaltene Appretur ist äußerst waschbeständig. Auch nach wiederholten Wäschen ist die Scheuerfüstigkeit des Gewel)cs bedeutend besser als die von unbehandQltem G.c,#x-ebe. Mit ähnlichem Erfolg läßt sich die Oxyäthvlrnetliylccllulos-c durch Stärke oder Dextrin ersetzen. Beispiel 2 Mit einer Lösung Von 2o Teilen Polvvinvlallohol in iooo Teilen Wasser wird ein Gewebe atis'Viskosekunstseide geklotzt. -Nach dem Trocknen leitet man über das Gewebe bei i-to' etwa io Minuten lang einen init d#impffi#rmi#,-eiii 1-lexanietli"-Icndiisocvanat beladen-en Stickstoffstroni. 'Man kann 1-nit gleichem Erfolg auch unter vermindertem Druck verdampftes Hexamethvlendiisocvali#it zür -z#n-\\-en,dting ])ringen. Auf dem dewebe enisteht auf diese #,#'eise eine sehr waschl).eständige Appretur. Beispiel 3 Eine Appreturmasse allS 2 Teilen Kartofielstärke und 18 Teilen Wasser wird mit io Teilen Talktim, io Teilen Kaolin, 4 Teilen eines schwarzen FarbstOffPigmellts und 3o Teilen einer io%igen w#ßrigen Lösung einer Alk-#?ln,-iI)lithalinstilfonsäiire angeteigt und auf Batimwollgem-ebe auf-estrichen. Nach dem Trocknen wird das G#pwebe mit einer Lösung von 34T,eile,n Hexameth#,Icn(Iii,#ocvanat in iooo Teilen Tetrachlorkohlenstofi getränkt und dann bei 140' _S Minuten getrocknet. Die Appretur wird dadurch so wasserbeständig auf dem Gewebe fixiert, daß sie selbst durch längeres Beregnen nicht abgelöst wird. Das so behandelte Gewebe ist für Verdunklungsstoffe, Chintzartil<cl, Bilchbinderleinen u. dul. hervorragend geeignet. Beispiel 4 Ungeleimtes Papier wird mit einer Lösung von 35 Teilen Knochenleim und 4 Teilen Natriumhydroxyd in iooo Teilen Wasser getränkt, kurz abgequetscht und getrocknet. Das so vorbeliandelte Papier wird mit einer Lösung von 25 Teilen To-Itiylen-p-diisocyanat in iooo Teilen Aecton getränkt und dann 30 Minuten auf T20' erhitzt. Die Festigkeit des Papiers "vird durch diese Behandlung be- deutend erhöht, außerdem wird das Papier weitgehend wasserundurchlässig. Beispiel -9 Mit einer Lösung VOn 2oo Teilen Polyvinylacetat in iooo Teilen Wasser wird eine Streichappretur auf Baumwollgewebe hergestellt. Man preßt sodann auf die bestrichene Seite dieses Gewebes ein gleich groß-es unbehandeltes Stück Gewebe und kalandert bei 105', bis die so erhaltene Doubli,erung trocken ist. Der Stoff wird nun mit einer Lösung von,4o Teilen Hexametliylendiisoc#-anat in iooo Teilen Tetrachlorkohlcnstoff getränkt, bei Raurntemperattir kurz getrocknet und dann 2o ---\lintiten lang auf i4o' erhitzt. Man erhält so einen ausgezeichnet wasserundurchlässigen Zeltbalinstoff von bedeutender Festigkeit.The parts given in the following examples are parts by weight. Example i 3o parts Oxäthvlmethylcellulose are dissolved in i ooo parts of water; cellulose tissue is impregnated with this solution. Then the fabric is squeezed off until it weighs only twice its dry weight and dried. The fabric pretreated in this way is impregnated with a solution of 34 parts of hexamethylene diisoeyanate in 1,000 parts of acetone and heated to 130 ° for 20 minutes. The finish obtained in this way is extremely washable. Even after repeated washes, the abrasion resistance of the gel) cs is significantly better than that of untreated Gc, # x-ebe. Oxyäthvlmnetliylccllos-c can be replaced by starch or dextrin with similar success. EXAMPLE 2 A solution of 20 parts of Polvvinvlallohol in 1,000 parts of water is padded to a fabric of viscose artificial silk. After drying, one passes over the fabric at i-to 'for about ten minutes an init d # impffi # rmi #, - eiii 1-lexanietli "-Indiisocvanat-laden-en nitrogen stroni.'

Example 4 Unsized paper is impregnated with a solution of 35 parts of bone glue and 4 parts of sodium hydroxide in 1,000 parts of water, briefly squeezed off and dried. The paper pre-treated in this way is impregnated with a solution of 25 parts of to-itiylene-p-diisocyanate in 1,000 parts of Aecton and then heated to T20 ' for 30 minutes. The strength of the paper "vird by this treatment increased loading pointing, also the paper substantially impermeable to water. Example -9 with a solution of polyvinyl acetate in 2oo parts iooo parts of water is a Streichappretur on cotton fabric prepared. One then pressed onto the coated side of this Tissue, an untreated piece of fabric of the same size and calendered at 105 ' until the resulting duplication is dry. The fabric is then impregnated with a solution of 40 parts of hexamethylene diisocyanate in 1000 parts of carbon tetrachloride and dried briefly at room temperature and then heated for 2o --- \ lintiten to 14o '. In this way an extremely water-impermeable canvas fabric of considerable strength is obtained.
