Description
Mit Titandioxyd spinnmattierte Kunstseiden aus regenerierter Cellulose lassen sich bekanntlich mit Substantiven Farbstoffen nicht lichtecht färben, da die gefärbte Kunstseide im feuchten Zustand ausbleicht. Im Sonnenlicht kann das Ausbleichen sogar schon nach wenigen Minuten festgestellt werden. Direktfarbstoffe, welche dieses Ausbleichen zeigen, sind Chlorazol Orange PO (Schultz, Farb-Stofftabellen, 7. Auflage, Nr. 747), Chlorazol OrangeBraunX (Schultz, a.a.O., Nr.678), Chlorazol echt Schwarz BK (Schultz, Farbstofftabellen, 7. Auflage, Bd. II, S. 33) und Chlorazol echt Rot F (Schultz, a.a.O., Nr. 410. (Die Zahlenangaben in Klammern beziehen sich auf Schultz, Farbstofftabellen, 7. Auflage, Bd. I.) In vielen Fällen wird gefärbte Viscoseseide zwar nur wenig oder gar nicht der Feuchtigkeit ausgesetzt; in anderen Fällen, wie beispielsweise bei Strumpfwaren und anderen schweren Stoffen, wie beispielsweise Plüsch, die Wasser in sich aufnehmen, ist jedoch nicht zu vermeiden, daß die feuchten Stoffe dem Sonnenlicht ausgesetzt werden. In diesen Fällen findet auch immer ein Ausbleichen statt.As is well known, rayon made from regenerated cellulose and spun-matted with titanium dioxide can be used Do not dye lightfast with nouns dyes, as the dyed rayon fades when wet. The fading can even lessen in sunlight a few minutes. Direct dyes that show this fading are Chlorazol Orange PO (Schultz, color tables, 7th edition, No. 747), Chlorazol OrangeBraunX (Schultz, op. Cit., No. 678), chlorazole real black BK (Schultz, Dye tables, 7th edition, vol. II, p. 33) and chlorazole real red F (Schultz, a.a.O., No. 410. (The figures in brackets refer to Schultz, color tables, 7th edition, Vol. I.) In many cases, colored viscose silk is only slightly or at all not exposed to moisture; in other cases, such as hosiery and other heavy materials, such as plush, that absorb water, however, it cannot be avoided that the moist substances are exposed to sunlight. In these cases, fading always takes place.
Es hat sich nun herausgestellt, daß dieser Nachteil vermieden werden kann und die Lichtechtheit substantiver Färbungen auf Kunstseide aus regenerierter Cellulose, die unter Verwendung von Titandioxyd spinnmattiert worden ist, verbessert werden kann, wenn man Mattkunstseide färbt, die nach dem Mattieren oder vor dem Färben mit wasserlöslichen Chromverbindungen behandelt worden ist.It has now been found that this disadvantage can be avoided and the Lightfastness of substantive dyeings on rayon made from regenerated cellulose, the has been spin-matted using titanium dioxide, can be improved, when dyeing matte artificial silk after matting or before dyeing with water-soluble ones Chromium compounds has been treated.
Die Behandlung kann beispielsweise in der Weise erfolgen, daß die spinnmattierte Viscoseseide in eine heiße wäßrige Lösung der betreffenden Chromverbindung eingetaucht und dann in der üblichen Weise gefärbt wird. Die so behandelten Stoffe können vor dem Färben gespült und getrocknet werden.The treatment can be carried out, for example, in such a way that the spun-matt viscose silk is immersed in a hot aqueous solution of the chromium compound in question and then colored in the usual way. The fabrics treated in this way can be rinsed and dried before dyeing.
In dem folgenden Beispiel sind einige Ausführungsformen der Erfindung angegeben. Die Teile sind Gewichtsteile.Some embodiments of the invention are given in the following example. The parts are parts by weight.
Durch Einverleiben von Titandioxyd mattierte Kunstseide aus regenerierter Cellulose wird 1I2 Stunde lang bei 850C in einer o,S prozentigen wäßrigen Natriumbichromat- oder Chromchloridlösurig behandelt, mit Was- · ser gespült, gegebenenfallsi getrocknet und mit einem der obengenanten Farbstoffe, wie üblich, gefärbt. 1 I 2 hour per cent at 85 0 C in an o, S aqueous Natriumbichromat- or Chromchloridlösurig is by incorporating titanium dioxide matted rayon of regenerated cellulose, rinsed with water · ser, and with gegebenenfallsi dried one of the above-mentioned dyes, as usual , colored.
