Description

Verfahren zum Veredeln von Cellulose- und Cellulosederivatfasergut Gegenstand des Patents 688 119 ist ein Verfahren zum Veredeln von Cellulose-und Cellulosederivatfasergut, das dadurch gekennzeichnet ist, daß die Ware mit Lösungen von höheren Alkyl- oder Naphthenisocyanaten oder Fettsäureaziden mit mindestens io C-Atomen, wobei die Alkylisocyanate im Alkylrest Heteroatome bzw. Heteröatomgruppen enthalten können, unter Nacherhitzung behandelt wird.Process for refining cellulose and cellulose derivative fiber material The subject of the patent 688 119 is a process for refining cellulose and Cellulose derivative fiber product, which is characterized in that the product contains solutions of higher alkyl or naphthene isocyanates or fatty acid azides with at least io carbon atoms, the alkyl isocyanates in the alkyl radical being heteroatoms or heteroatom groups may contain, is treated with reheating.

Es wurde nun gefunden, daß man in weiterer Ausbildung dieses Verfahrens mit gleicher Wirkung so arbeiten kann, daß man das Fasergut an Stelle mit Lösungen von aliphatischen Isocyanaten mit Lösungen von einen gesättigten aliphatischen Rest mit mindestens i o C-Atomen enthaltenden- aromatischen Isocyanaten tränkt und danach einer Wärmenachbehandlung unterwirft: Die erfindungsgemäß anzuwendenden aromatischen Isocyanate können solche sein, bei denlen der aromatische Rest chlorsubstiriüert ist.It has now been found that this process can be further developed can work with the same effect that the fiber material in place with solutions of aliphatic isocyanates with solutions of a saturated aliphatic radical with at least 10 carbon atoms containing aromatic isocyanates and then impregnated subject to post-heat treatment: The aromatic to be used according to the invention Isocyanates can be those in which the aromatic radical has chlorine substitution is.

Beispiel Ein Regenmantelstoff, dessen Kette und Schuß aus spinnmattenViscosekunsts-eidefäden besteht, wird mit einer o,5%igen Lösung des Isocyanats erhältlich durch Überführen von p-Stearoyloxybenzoesäure mit Thionylchlorid in das Säurechlorid und dieses letzteren nach N e 1-1 e s .aktiviertem Natriumazid (Berichte der Deutschen Chem. Gesellschaft 1932, 1345/46) in das Azid bzw. Isocyanat, in Benzin getränkt und darauf einige Minuten auf ioo bis 14o° erhitzt. Das Textilgut ist nach dieser Behandlung waschbeständig wasserabstoßend.EXAMPLE A raincoat fabric, the warp and weft of which consists of spun-matt viscose synthetic silk threads, is treated with an 0.5% solution of the isocyanate obtainable by converting p-stearoyloxybenzoic acid with thionyl chloride into the acid chloride and this latter after N e 1-1 es. Activated sodium azide (reports of the Deutsche Chem. Gesellschaft 1932, 1345/46) into the azide or isocyanate, soaked in gasoline and on it heated to 100 to 14o ° for a few minutes. After this treatment, the textile is washable and water-repellent.
