Description

Verfahren zur Verbesserung der Echtheit von Färbungen auf Textilfasern Es ist bekannt, daß bei Färbungen auf Mischgeweben aus Wolle und Baumwolle mit Substantiven Farbstoffen durch eine Nachbehandlung mit Chromkali, Formaldehyd, Essigsäure bei höherer Temperatur die Waschechtheit verbessert wird, wobei jedoch gleichzeitig der Farbton sich mehr oder weniger verändert.Process for improving the fastness of dyeings on textile fibers It is known that when dyeing on blended fabrics of wool and cotton with nouns Dyes by post-treatment with chromium potassium, formaldehyde, and acetic acid higher temperature the wash fastness is improved, but at the same time the hue changes more or less.

Es ist nun gefunden worden, daß man nicht nur die Waschechtheit solcher Färbungen, Sondern auch die Wasser-, Dekatur- und Bügelechtheit verbessern kann, wobei gleichzeitig eine Veränderung des Farbtons vermieden wird, wenn man Textilfasern aller Art, tierischen oder pflanzlichen Ursprungs, sowie Kunstseide oder Mischgeweben aus diesen Fasern mit Bichromat, Formaldehyd und einem Sauren Aluminiumsalz behandelt. Diese Behandlung findet zweckmäßig bei niedriger Temperatur, z. B. zwischen 3o bis 4o° C, statt.It has now been found that not only the washing fastness of such Dyeing, but can also improve the fastness to water, decatur and ironing, at the same time a change in color is avoided when using textile fibers of all kinds, of animal or vegetable origin, as well as rayon or blended fabrics treated from these fibers with bichromate, formaldehyde and an acidic aluminum salt. This treatment is expediently carried out at a low temperature, e.g. B. between 3o to 40 ° C instead.

Beispiel. Eine dunkelblaue Färbung auf Halbwollstoff (weiße Baumwollkette und weißer, reinwollener Streichgarnschuß), hergestellt mit 4% Naphthaminschwarz CE (Schultz, Farbstofftabellen, 5. Aufl., Nr. 3 3 ;) und r, 5 Azocyanin GR (Colour Index Nr. 288) in der für Halbwolle üblichen Weise, wird auf der Waschmaschine bei 3o bis 4.o° C unter Zusatz von i bis 2 °/o Chromkali, 2 % Alaun und i bis 3 °/o Formaldehyd io Minuten gespült, auf den Rahmen gespannt und fertiggemacht.Example. A dark blue dye on semi-wool fabric (white cotton warp and white, pure wool carded yarn weft), made with 4% naphthamine black CE (Schultz, Dyestuff Tables, 5th edition, No. 3 3;) and r, 5 azocyanine GR (Color Index No. 288) In the usual manner for half wool, it is rinsed on the washing machine at 3o to 4o ° C with the addition of 1 to 2 % potassium hydroxide, 2% alum and 1 to 3% formaldehyde for 10 minutes, stretched on the frame and ready.

Während die Wasser-, Bügel- und Dekaturechtheit dieser Färbung vor der Behandlung eine nur mäßige war, ist sie nach der Behandlung ausgezeichnet.While the water, iron and deca fastness of this dye If the treatment was only moderate, it is excellent after the treatment.

Die zu dem vorliegenden Verfahren notwendigen Produkte können auch, um die Arbeitsweise dem Verbraucher zu erleichtern, in Gestalt einer Mischung hergestellt werden. Eine solche Mischung wird z. B. erhalten, indem man etwa ¢o Teile Formaldehyd mit etwa 3o Teilen Kaliumbichromat und 3o Teilen Alaun auf dem Kollergang bis zur Trockne vermahlt.The products required for the present process can also in order to facilitate the operation of the consumer, made in the form of a mixture will. Such a mixture is e.g. B. obtained by adding about ¢ o parts of formaldehyde with about 3o parts of potassium dichromate and 3o parts of alum on the pan mill up to Milled dry.

Es tritt hierbei keine Oxydation des Formaldehyds zu Ameisensäure ein, sondiern die drei Mischungsbestandteile bleiben in haltbarer Form nebeneinander bestehen.There is no oxidation of the formaldehyde to formic acid one, the three components of the mixture remain side by side in a durable form exist.
