Die Erfindung l>ezieht sich auf ein Verfahren zur Verbesserung der Festigkeit von künstlichen:, un-. löslich gemachten Proteingespinsten, insbesondere der Art, Ixm der die Unlöslichmachung der koagulierten, durch Naßspinnen erzeugten Gespinste mit Hilfe von Formaldehyd in Gegenwart einer angesäuerten starken Salzlösung erfolgt.The invention relates to a method for improving the strength of artificial :, un-. solubilized protein webs, in particular of the kind that insolubilize the coagulated, webs produced by wet spinning with the help of formaldehyde in the presence of an acidified strong saline solution takes place.

Die Erfindung ist besonders· anwendbar auf unlöslich gemachte Gespinste, die aus alkalischen Lösungen von Casein und alkalischen Lösungen von pflanzlichen Globulinen hergestellt worden sind, beispielsweise Erdnußglobulinen oder Sojabohnenglobulinlösungen in verdünnter Natriumhydroxydlöstmig. The invention is particularly applicable to insoluble made webs made from alkaline solutions of casein and alkaline solutions of vegetable globulins, for example peanut globulins or soybean globulin solutions in dilute sodium hydroxide solution.

Die Unlöslichmachung der koagulierten, naß gesponnenen Proteinfasern kann vorteilhaft oder zweckmäßig mit Hilfe von Formaldehyd in Gegenwart einer angesäuerten, hoch konzentrierten wäßrigen Salzlösung, beispielsweise nach den in den britischen Patentschriften 513 910 oder 597497 beschriel >enen Verfahren, erfolgen. Das Unlöslichmachen der koagulierten, naß gesponnenen Proteinfasern kann auch gemäß dem Verfahren der britischen Patentschrift 533 952 erfolgen, bei dem die aus Casein oder pflanzlichem Saatprotein bestehenden Gespinste mit einer konzentrierten wäßrigen Lösung eines Salzes eines Halogenwasserstoffes behandelt werden, die Formaldehyd oder eine Verbindung enthält, die unter den obwaltenden Arbeitsbedingungen Formaldehyd ergibt, außerdem ein Salz einer reduzierenden Schwefelsäure, in der das Atomverhältnis von. Wasserstoff, falls solcher zugegen ist,The insolubilization of the coagulated, wet-woven Protein fibers can be beneficial or expedient with the help of formaldehyde in the presence an acidified, highly concentrated aqueous salt solution, for example after the in the British Patent 513,910 or 597497 > a procedure. Insolubilizing the coagulated, wet-spun protein fibers can also be done according to the method of British Patent 533 952, in which the from casein or vegetable seed protein existing webs with a concentrated aqueous Treated solution of a salt of a hydrogen halide that contains formaldehyde or a compound that is subject to the prevailing working conditions Formaldehyde results, moreover, a salt of a reducing sulfuric acid, in which the atomic ratio from. Hydrogen, if present,

In der britischen Patentschrift 639 342 ist u. a.British Patent 639,342, inter alia.

' ein Verfahren zur Verbesserung der Festigkeit von künstlichen, unlöslich gemachten Gespinsten beschrieben, in dem dlie unlöslich gemachten Gespinste unter Spannung mit einer wäßrigen Lösung eines ionisierbaren Mercurisalzes behandelt werden.'' describes a process for improving the strength of artificial, insoluble webs, in the dlie insolubilized web under tension with an aqueous solution of a ionizable mercury salt are treated.

Die Festigkeit von künstlichen Proteingespinsten kann auch dadurch verbessert werden, daß sie mit »5 Stoffen behandelt werden, die geeignet sind, in situ nas'zierenden monomeren Thioformaldehyd, beispielsweise gemäß der britischen Patentschrift 333 952> zu ergeben und Behandlung dieser Proteingespinste unter Spannung mit einer wäßrigen Löao sung von Mercurichlorid.The strength of artificial protein webs can also be improved by treating them with substances suitable for producing in situ nascent monomeric thioformaldehyde, for example according to British patent 333 95 2 , and treating these protein webs under tension an aqueous solution of mercury chloride.

In der britischen Patentschrift 639363 ist u.a. ein Verfahren zur Verbesserung der Festigkeit von künstlichen, unlöslich gemachten Gespinsten beschrieben, das darin besteht, daß die unlöslich gemachten Gespinste unter Spannung in einer wäßrigen Lösung von mindestens einem Uranylsalz behandelt wenden.In British Patent 639363 there is, inter alia, a method for improving the strength of artificial, insoluble webs described, which consists in the fact that the insoluble Treated webs under tension in an aqueous solution of at least one uranyl salt turn around.

Es wurde nun gefunden-, daß unlöslich gemachte Gespinste, welche mit Metalisalzen behandelt wurden, beispielsweise mit Salzen von Kadmium, Zink, Alumimium, Quecksilber, Uran und Chrom, leicht ihre verbesserte Festigkeit verlieren, wenn sie mit Säurelösungen, beispielsweise sauren Farbflotten, behandelt wurden.It has now been found that insolubilized webs which have been treated with metal salts for example with salts of cadmium, zinc, aluminum, mercury, uranium and chromium, easily lose their improved strength if they are treated with acid solutions, for example acidic dye liquors, were treated.

Zweck der Erfindung ist nunmehr, die Festigkeit von unlöslich gemachten Proteingespinsteni, die in sauren Färbebädern gefärbt worden sind, zu verl)essern, so daß sie leichter in den üblichen Färbeapparaturen der Textilindustrie verarbeitet werden können.The purpose of the invention is now to improve the strength of insolubilized protein spines which are present in have been dyed in acid dyebaths, so that they can be used more easily in the usual dyeing machines the textile industry can be processed.

Gemäß der Erfindung besteht das Verfahren zur Verbesserung der Festigkeit von künstlichen, unlöslich gemachten Gespinsten der angegebenen Art darin, daß die unlöslich gemachten Gespinste nach der Färbebehandl'Uing vorzugsweise unter Spannung in einer wäßrigen Lösung eines Salzes von Quecksilber, Uran, Chrom, Zink, Kadmium oder Aluminium behandelt werden.According to the invention, the method for improving the strength of artificial, insoluble made webs of the specified kind in that the insoluble made webs after dyeing treatment, preferably under tension in an aqueous solution of a salt of mercury, Uranium, chromium, zinc, cadmium or aluminum can be treated.

Die Salze, die sich für die Zwecke der Erfindung als besonders geeignet erwiesen haben, sind Mercuriacetat, Uranylacetat, basisches Chromsulfat, Aluminiumsulfat, Zinkchlorid und Kadmiumacetat, Es ist zweckmäßig, daß die Lösung dieser Salze, mit Ausnahme der Quecksilbersalze, Formaldehyd enthält. Die angewandten Fasern sind solche, diemitHilfevon sauren Egalisierungsfarbstoffen, sauren Wollfarbstoffen, welche Ausfärbungen ergeben, die besonders widerstandsfähig sind gegenüber mechanischer Behandlung der gefärbten Produkte in sauren oder alkalischen Bädern oder Chromfarbstoffen gefärbt worden sind, oder Fasern, die dadurch gefärbt wurden, daß Pigmente oder Farbstoffe der Spinnlösung selbst einverleibt wurden.The salts which have been found to be particularly suitable for the purposes of the invention are mercuric acetate, Uranyl acetate, basic chromium sulfate, aluminum sulfate, Zinc chloride and cadmium acetate, It is convenient that the solution of these salts, except which contains mercury salts, formaldehyde. The fibers used are those made with the help of acidic leveling dyes, acidic wool dyes, which result in colorations that are particularly special Are resistant to mechanical treatment of the colored products in acidic or alkaline baths or chromium dyes, or fibers that have been colored by them, that pigments or dyes were incorporated into the spinning solution itself.

Es ist zweckmäßig, daß das Gewichtsverhältnis der Lösung, welche das metallische Salz enthält, zu dem Gewicht der Fasern der Größenordnung von 30 : ι ist.It is appropriate that the weight ratio of the solution containing the metallic salt, to the weight of the fibers is of the order of 30: ι.
