2. A method for single-bath dyeing of mixtures of polyester fibers and wool, characterized through the use of dye mixtures according to claim 1.

In practice, there is seldom a color for it given suitable dye, which has proven to be beneficial in terms of this phenomenon.

The tone of a color is determined by the spectral composition of the incident and the reflective Defined by light. Becomes one and the same color with differently composed light sources viewed, it can be perceived in different ways in its nuance. As the composition of artificial light different from those of them; of daylight show many tints an "evening fairy" deviating from the "daytime color". A change in the light source thus affects the color tone.

It is known that the evening color eLie through Artificial light, more precisely GKihlampenlicht, evoked Shifting the nuance of body colors towards red or green. This "shade change can sometimes be felt so strongly that the color stimulus conveyed to the eye is a blue-colored one Fabric turns violet under the lighting with artificial light. Even with coloring on mixtures of polyester fibers and wool with this phenomenon. A definite bicoloi effect can be the consequence of this. Especially when dyeing royal blue tones on these fiber mixtures There is a problem that the blue dyes both the wool dyes and the Disperse dyes reproduce a very different ■ evening color. It was in that context therefore hardly possible to mix a dye to find. whose components are one-sided, but rather absorb in the broadest possible spectral range, d. H. which, in all types of light, are related to you Appearance of dyeings produced with it on the polyester fiber as well as on the wool fiber portion behave similarly to the goods.

Special attention has been paid to this fact because the dye-making process "." to a large extent have gone over to combinations of disperse and acid or metal complex dyes for the one-bath dyeing of blends of polyester fibers and wool together to deliver. Such mixtures of dyes enable in in practice a number of advantages, such as At the Facilitation of dye selection, or easier handling of these dyes, simpler Dissolving and dispersing.

Surprisingly, it has now been found that, when using dye mixtures, consisting of

a) one or more disperse dyes of the general formula

Dyes on wool have always been judged on the part of customers especially with regard to their color. To produce those in which Ri is a hydroxyl or hydroxymethylamino group and R _{2 is} a hydroxyl, amino or hydroxymethylamino group, where the radicals R ₁ and R _{2 are} always different and R _{3 is} a hydrogen atom or a phenol or anisole radical,

Another advantage of using the explained I, dye mixtures is e.g. the fact that these Dyes can be determined on the basis of remission curves and so for the pre-calculation the concepts can be grasped. Besides it results also a better Γοη-in-Ton-Fürbunc. It is also surprising that with one-bath dyeing With the dye mixtures according to the invention, the soiling of the wool fiber content of the goods is caused the dispersion dye somewhat in most cases is less than the color of the individual components.

For carrying out the dyeings with the dye combinations mentioned, all are connected Suitable dyeing methods for conventional dyeing methods with polycster fiber-wool blends: peeling process at cooking temperature and at a higher temperature (106 to 108 "C) with the usual carriers, continuous dyeing processes, such as the thermosol process or the HT pressure steaming process. Also the processing state of the used :!

thus no more cumbersome or difficult procedures. The mixing ratio of the individual components of the dye mixtures according to the invention can fluctuate within wide limits; it generally depends on the composition of the textile

materials dependent on polyester fibers and wool.
