Description

Verfahren zum Färben von Mischgeweben aus Fasern pflanzlichen Ursprungs und regenerierter Cellulose mit substantiven Farbstoffen Mischgewebe aus Fasern pflanzlichen Ursprungs, insbesondere Baumwolle, und regenerierter Cellulose, wie Viscose- und Kupferseide, werden mit substantiven Farbstoffen im allgemeinen aus dem Glaubersalzbade gefärbt. Da die regenerierte Gellulose nun ein stärkeres Ziehvermögen hat als die pflanzliche Faser, sind die erhaltenen Färbungen nicht gleich stark, sondern die der pflanzlichen Faser erscheint heller als die der regenerierten Cellulose.Process for dyeing blended fabrics made from fibers of vegetable origin and regenerated cellulose with substantive dyes. Mixture of fibers of vegetable origin, especially cotton, and regenerated cellulose, such as Viscose and copper silk are generally made with substantive dyes colored by the Glauber's salt bath. Because the regenerated cellulose now has a stronger drawability than the vegetable fiber, the colorations obtained are not equally strong, but that of the vegetable fiber appears lighter than that of the regenerated cellulose.

Es wurde nun gefunden, daß beim Färben von Mischgeweben der genannten Art der Unterschied in der Farbstärke der verschiedenen Fasern verringert wird, wenn man aus einem Bade färbt, das ein wasserlösliches Magnesiumsalz, insbesondere ein solches einer starken Säure, bzw. Mischungen solcher Salze und gegebenenfalls Natriumsulfat enthält. Beispiel Ein Mischgewebe aus Baumwolle und Viscoseseide wird mit ¢% Benzochrombraun B (s. S chultz, Farbstofftabellen, 1914, S. 372) unter Zusatz von 17,5 % Magnesiumsulfat und o, 5 % Oleylmethyltaurin bei einem Flottenverhältnis 1:30 1/2 Stunde bei 85° C gefärbt. Gegenüber der in üblicher Weise hergestellten Färbung aus dem Glaub@ersalzbade sind in dem Mischgewebe die Färbungen der Baumwolle und der Viscoseseide in der Farbtiefe stark angeglichen.It has now been found that when dyeing mixed fabrics of the type mentioned, the difference in the color strength of the various fibers is reduced if dyeing is carried out from a bath containing a water-soluble magnesium salt, in particular one of a strong acid, or mixtures of such salts and optionally Contains sodium sulphate. EXAMPLE A mixed fabric made of cotton and viscose silk is made with [%] benzochrome brown B (see S chultz, Dye Tables, 1914, p. 372) with the addition of 17.5 % magnesium sulfate and 0.5% oleylmethyltaurine at a liquor ratio of 1:30 1/2 Stained at 85 ° C for one hour. Compared to the dyeing produced in the usual way from the Glauber salt bath, the dyeing of the cotton and the viscose silk in the mixed fabric are strongly matched in terms of color depth.

Ersetzt man das Magnesiumsulfat durch die gleiche Menge Magnesiumchlörid, so erhält man eine ähnliche Wirkung.If you replace the magnesium sulfate with the same amount of magnesium chloride, this gives a similar effect.
