Description
Verfahren zum Färben von Cellulosefasern mit eisenempfindlichen basischen und substantiven Farbstoffen in Gegenwart von Eisen oder Eisenverbindungen Beim Färben von Cellulosefasern in wässerigen Flotten treten vielfach Nachteile auf, wenn diese Behandlung in Anwesenheit von Eisen oder von Eisenverbindungen durchgeführt wird. Das Eisen oder die Eisenverbindungen können dabei auf verschiedene Weise in die -Flotten gelangen, z. B. aus eisernen Apparateteilen, durch eisenhaltige Zusätze zum Färbebade oder durch Verwendung eisenhaltigen Wassers; z. B. wird beim Färben mit einer großen Anzahl basischer und substantiver Farbstoffe der erzielte Farbton durch die Anwesenheit von Eisen oder seinen Verbindungen ungünstig beeinflußt.Process for dyeing cellulose fibers with iron-sensitive basic and substantive dyes in the presence of iron or iron compounds There are many disadvantages to dyeing cellulose fibers in aqueous liquors, when this treatment is carried out in the presence of iron or iron compounds will. The iron or the iron compounds can be used in various ways the fleets arrive, e.g. B. from iron parts of the apparatus, by ferrous additives for dye bath or by using iron-containing water; z. B. is when dyeing with a large number of basic and substantive dyes, the hue achieved adversely affected by the presence of iron or its compounds.
Es wurde nun gefunden, daß diese Nachteile und Schädigungen in einfacher Weise dadurch verhindert werden können, daß man das Färben in Gegenwart von Amiden höherer Fettsäuren vornimmt, die im Fettsäurerest sulfoniert sind. Von solchen Verbindungen seien beispielsweise das sulfonierte Ölsäureäthylanilid oder das sulfonierte ölsäurediisobutylamid genannt. Weitere derartige Verbindungen sind z. B. in der französischen Patentschrift 693 62o genannt. Im allgemeinen genügen schon geringe Zusätze der sulfonierten Fettsäureamide, beispielsweise Mengen von o, F bis 3 g je Liter Flotte. Die sulfonierten Fettsäureamide können dabei in der Form verwendet werden, in der sie bei der Herstellung anfallen, d. h. mit :einem gewissen Gehalt an unsulfonierten Anteilen oder freien Fettsäuren. Durch die Anwesenheit dieser Verbindungen wird die ungünstige Wirkung des Eisens auf den Farbton gefärbter cellulosehaltiger Textilfaserstoffe verhindert. Beispiel i Baumwolle wird in üblicher Weise gebeizt und mit i 0,'o Thioflavin T (S c h u 1 t z, Farbstofftabellen, 7. Auflage, Nr.934) in einem Eisengefäß unter Zusatz von 0,3 g des im Fettrest sulfonierten ölsäuredüsobutylamids gefärbt. Der Farbton entspricht dem einer Färbung, die in Abwesenheit von Eisen hergestellt ist. Beispiel e Man färbt Viscosegarn, wie üblich, mit i, 5 ojo D iaminreinblau FF (S c h u 1 t z, a. a. O., Nr. 51 o) im eisernen Becher unter Zusatz von i g des im Beispiel i genannten Amids. Die im Eisenbecher hergestellte Färbung zeigt den gleichen Farbton wie die in einem Porzellanbecher hergestellte Färbung. Beispiel 3 Baumwollgarn wird in üblicher Weise auf einer eisernen Färbevorrichtung mit 1,50/0 Brillantreinblau R (Schultz, a. a. O., Nr. 8i7) unter Zusatz von 2 g des im Beispiel i genannten Amids gefärbt. Die Färbung ist sogar lebhafter als die in einer Färbevorrichtung aus nichtrostendem Stahl ohne Zusatz des Amids erhaltene Färbung.It has now been found that these disadvantages and damage can be prevented in a simple manner by carrying out the dyeing in the presence of amides of higher fatty acids which are sulfonated in the fatty acid residue. Examples of such compounds are sulfonated oleic acid ethylanilide or sulfonated oleic acid diisobutylamide. Other such compounds are, for. B. mentioned in French patent specification 693 62o. In general, even small additions of the sulfonated fatty acid amides, for example amounts of 0.5 to 3 g per liter of liquor, are sufficient. The sulfonated fatty acid amides can be used in the form in which they are obtained during production, ie with: a certain amount of unsulfonated components or free fatty acids. The presence of these compounds prevents the unfavorable effect of iron on the color shade of dyed cellulosic textile fibers. Example i Cotton is stained in the usual way and dyed with 10, o thioflavin T (S chu 1 tz, Dye Tables, 7th Edition, No. 934) in an iron vessel with the addition of 0.3 g of the oleic acid diisobutyl amide sulfonated in the fat residue. The hue corresponds to that of a color produced in the absence of iron. Example e Viscose yarn is dyed, as usual, with 1.5 oo D iaminreinblau FF (S chu 1 tz, loc. Cit., No. 51 o) in an iron cup with the addition of ig of the amide mentioned in Example i. The color made in the iron cup shows the same shade as the color made in a porcelain cup. Example 3 Cotton yarn is dyed in the usual way on an iron dyeing device with 1.50 / 0 brilliant pure blue R (Schultz, loc. Cit., No. 8i7) with the addition of 2 g of the amide mentioned in example i. The coloring is even more vivid than that obtained in a stainless steel coloring machine without the amide added.
