Description

Verfahren zum Veredeln von Cellulose- und Cellulosederivatfasergut Zum Wasserabstoßendmachen von Textilien ist vorgeschlagen worden, durch eine leichte oberflächliche Anesterung mit Hilfe höherer Fettsäurechloride oder -anhydride dem Textilgut Widerstandsfähigkeit gegen Benetzwig mit Wasser zu erteilen. Die Verwendung höherer Fettsäurechloride ist jedoch praktisch ausgeschlossen, da beim Arbeiten mit diesen Verbindungen seabst bei Gegenwart tertiärer Basen infolge Salzsäwreabspaltumg stets Faserschwächungen eintreten. Die höheren Fettsäureanhydride sind dagegen für die Faser unschädlich , zeigen jedoch gegenüber den Fettsäurechloriden ein erheblich geringeres Reaktionsvermögen.Process for refining cellulose and cellulose derivative fiber material For making textiles water repellent has been proposed by a lightweight superficial esterification with the help of higher fatty acid chlorides or anhydrides To give textile goods resistance to wetting with water. The usage However, higher fatty acid chlorides is practically excluded because when working with these compounds self in the presence of tertiary bases as a result of Salzsäwreabspaltumg fiber weakening always occur. The higher fatty acid anhydrides, on the other hand, are for the fibers are harmless, but show a considerable compared to the fatty acid chlorides less responsiveness.

Erfindungsgemäß wird Gellulose- oder Cellulosederi,vatfasergut in Form von Fasern, Garnen oder Geweben aus Baumwolle, Jute, Leinen, Hanf, Kunstseide und ihren Abkämmlingen, Zellwolle aus Cellulosekunstfaser u. dgl. dadurch veredelt und insbesondere -wasserabstoßend gemacht, daß man die Ware mit Lösungen von höheren Alkyl- oder Naphthenisocyanaten oder von Fettsäureaziden mit wenigstens roKohlenstoffatomen im Molekül behandelt. Bekanntlich reagiert C.ellulose. mit Isocyansäureestern unter Bildung der entsprechenden Carbamidsäureester, während die Fettsäureazde sich leicht in die Isocyansäureester umwandeln und dann wie diese reagieren.According to the invention, Gellulose- or Cellulosederi, vatfasergut in Form of fibers, yarns or fabrics made from cotton, jute, linen, hemp, rayon and their combed-offs, rayon made of cellulose synthetic fiber and the like are refined in this way and in particular - made water-repellent that you can treat the goods with solutions of higher Alkyl or naphthene isocyanates or of fatty acid azides with at least raw carbon atoms treated in the molecule. As is well known, C.ellulose reacts. with isocyanic acid esters below Formation of the corresponding carbamic acid ester, while the fatty acid azde easily convert into the isocyanic acid esters and then how they react.

Für die Behandlung kommen in erster Linie die äußerst reaktionsfähigen Alkylisocyansäureester, wie Decylisocyanat oder HeptadecylisG.cyanat, in Betracht, die in bekannter Weise, z. B. durch Curtiusschen Abbau der Säurechloride oder durch Umsetzung von Gemischen aus hochmolekularen, gesättigten Aminen, z. B. der aus hydrierten Tranfettsäuren technisch zugänglichem Amine, mit Phosgen und nachfolgender Salzsäureabspaltung, erhältlich sind. Der aliphatische Rest kann hierbei aus einer normalen oder verzweigten Kette von Kohlenstoffatomen bestehen. Die Iso,cyanate können auch aus, ,den durch Oxydation von ParaffInkohlenwasserstoffen hergestellten Carbonsäuren gewonnen werden. Ferner sind Alkyliso-cyanate geeignet, die irn. Alkylrest Heteroatome oder -atomgrupp.en, wie 0, S, CO-0, O . C O, NR, NR#CO, CO#NR, S02, NR#S02, S 02 # N R, wobei R Wasserstoff oder einen Kohlenwasserstoffrest bedeutet, aufweisen, z. B. Dodecylthiomethylisocyanat oder Carbonylglyzindodecylester.Those who are extremely reactive come first for treatment Alkyl isocyanic acid esters, such as decyl isocyanate or heptadecyl isG.cyanate, into consideration, which in a known manner, for. B. by Curtius degradation of the acid chlorides or by Implementation of mixtures of high molecular weight, saturated amines, e.g. B. from hydrogenated Tran fatty acids technically accessible amines, with phosgene and subsequent elimination of hydrochloric acid, are available. The aliphatic radical can consist of a normal or branched one Chain of carbon atoms. The Iso, cyanate can also be made from,, den by Oxidation of carboxylic acids produced by paraffin hydrocarbons. Furthermore, alkyl isocyanates are suitable, which in. Alkyl radical heteroatoms or atom groups, like 0, S, CO-0, O. CO, NR, NR # CO, CO # NR, S02, NR # S02, S 02 # N R, where R is hydrogen or denotes a hydrocarbon radical, e.g. B. dodecylthiomethyl isocyanate or carbonyl glycine dodecyl ester.

Die Imprägnierung des Textilgutes kann mit Lösungen der genannten Verbindungen in organischen Lösungsmitteln oder mit wässerigen Dispersionen dieser Verbindungen durch Tränken, Spritzen o.dgl. und nachträgli-chcr Wärmeeinwirkung, beispielsweise durch Anhitzen.des Bades oder nachträgliches Erhitzen der Textilien, bewirkt werden. Man kann die Kunstfasern aus Cellulose oder Celluloseabkömm:ingen auch unmittelbar anschließend an das Spinnverfahren mit den genannten Verbindungen behandeln. Der Zusatz von Katalysatoren zur Erzielung der gewünschten Wirkung ist nicht unbedingt erforderlich. Die Imprägnierung isst auch gegenüber wiederholter Wäsche beständig.The textile material can be impregnated with solutions of the aforementioned Connections in organic solvents or with aqueous dispersions these compounds by soaking, spraying or the like. and subsequent heat exposure, for example by heating up the bath or subsequent heating of the textiles, be effected. The synthetic fibers can be made from cellulose or derived from cellulose also immediately following the spinning process with the compounds mentioned treat. The addition of catalysts to achieve the desired effect is not necessarily required. The impregnation also eats against repeated Wash resistant.

Das behandelte Textilgut aus Kunstseide oder Kunst.spinnfas@ern zeigt neben derwasserabweisenden Wirkung auch noch eine Steigerung der Trocken- und Naßfestigkeit.The treated textile material made of rayon or Kunst.spinnfas@ern shows In addition to the water-repellent effect, there is also an increase in dry and wet strength.

Es ist zwar bereits bekannt, Textilien mit aromatischen Isocyanaten zu behandeln. Hierbei werden jedoch nur die färberischen Eigenschaften der Fasern verändert, nicht jedoch eine wasserabstoßendmachende Wirkung erzielt.Although it is already known, textiles with aromatic isocyanates to treat. Here, however, only the dyeing properties of the fibers are taken into account changed, but not achieved a water-repellent effect.

Beispiele i. Ein bedruckter Mattkrepp, dessen Kette aus matter Kupferkunstseide und dessen Schuß .aus Viscosekrepp besteht, wird durch eine o,5pro-zentige Lösung von H,eptadecylisocyanat in Benzin geführt, anschließend i Minute lang einer Temperatur von ioo° C und dann weitere a Minuten lang einer Temperatur von iq.o° C ausgesetzt. Der behandelte Stoff ist alsdann wasserabstoßend und tropfenecht.Examples i. A printed matt crepe with a chain made of matt copper artificial silk and its weft. consists of viscose crepe, is replaced by an o, 5 percent solution of H, eptadecyl isocyanate in gasoline, then one minute for one temperature of 100 ° C and then exposed to a temperature of 100 ° C for a further a minutes. The treated fabric is then water-repellent and drip-proof.

Acetatkunstseidensatin, dessen Schuß aus Viscosekrepp und dessen Kette aus Acetatkunstseide besteht, wird mit einer iprozentigen Lösung von Dodecylisocyanat in Benzin bespritzt; das Lösungsmittel wird alsdann abgedunstet, und der Stoff wird z Minuten lang einer Temperatur von 13o° C a.usg wetzt.Acetate artificial silk satin, its weft of viscose crepe and its warp is made of acetate rayon, is mixed with an i% solution of dodecyl isocyanate splashed in gasoline; the solvent is then evaporated, and the substance becomes z minutes at a temperature of 130 ° C a.usg.

3. Gefärbte Strümpfe aus Kupferkunstseide werden in eine o,3prozentige Lösung von Heptakosylisocyanat in Benzin getaucht, sodann herausgenommen und nach Abdunsten des Lösungsmittels 45 Minuten lang auf i 5o° C erhitzt.3. Dyed stockings made of copper rayon are converted into a 0.3 percent Solution of heptacosyl isocyanate immersed in gasoline, then taken out and after The solvent was evaporated and heated to 150 ° C. for 45 minutes.
