Description

Verfahren zur Erzeugung von Färbungen auf der Baumwollfaser. Es hat sich gezeigt, daß substantive Farbstoffe, die chromierbare Gruppen enthalten, bei der Behandlung mit Chromverbindungen in lösliche (@hroinderivate übergeführt werden können. Die Farbstoffe haben hierbei überraschenderweise die Fähigkeit, Baum-«-olle substantiv anzufätben, nicht verloren, sondern liefern Färbungen von ausgezeichneten Echtheitseigenschaften.Process for producing colorations on cotton fibers. It has it has been shown that substantive dyes which contain chromable groups at treatment with chromium compounds can be converted into soluble (@hroin derivatives can. Surprisingly, the dyes have the ability to make tree - «- olle To be stained substantively is not lost, but provides colors of excellent quality Authenticity properties.

Die Fixierung auf der Faser kaim entweder in der Wärme oder in der Kälte geschehen. unter Umständen ist es vorteilhaft, namentlich in letzterem Falle, eine Nachbehandlung finit alkalisch wirkenden Mitteln vorzunehmen. Beispiel. io Teile des Azofarbstoffes 4#4'-Dianiinostilber-2 # 2'-disulfosäure -f- 2 Mol. Salicylsäure werden in doo Teilen Wässer gelöst und nach Zusatz von 5 Teilen krist. Natriumacetat mit ioo Teilen einer Chromsalzlösung gekocht, die in ioo Teilen Lösung etwa io Teile Chromoxyd (Cr,0,) enthält. Beispielsweise kann man zur Herstellung einer solchen Chromsalzlöscing ein Gemisch von etwa 6 'fol. Chromformiat. .4 Mol. Chromfluorid und i Mol. Chromisulfat verwenden.The fixation on the fiber came about either in the warmth or in the Cold happen. under certain circumstances it is advantageous, especially in the latter case, to undertake a follow-up treatment with finite alkaline agents. Example. ok Parts of the azo dye 4 # 4'-dianiinostilber-2 # 2'-disulfonic acid -f- 2 mol. Salicylic acid are dissolved in doo parts of water and after the addition of 5 parts of crystalline. Sodium acetate Boiled with 100 parts of a chromium salt solution, which is about 10 parts in 100 parts of the solution Contains chromium oxide (Cr, 0,). For example, you can produce such Chromium salt solution a mixture of about 6 'fol. Chromium formate. .4 moles of chromium fluoride and 1 mole of chromium sulfate.

ach etwa dreistündigem Kochen wird t?un, wenn nötig, filtriert, das Filtrat ausgesalzen und die abgeschiedene Chromv erbindung des Farbstoffes vorsichtig getrockiret. -Zum Färben der Baumwolle werden z. B. ioo Teile derselben mit 3 Teilen der Chromverbindung obigen Farbstoffs bei Gegenwart von Glauber- oder Kochsalz etwa eine Stunde heiß gefärbt, oder man hantiert mehrere Stunden bei gewöhnlicher Temperatur, spült kurz, geht mit der so gefärbten Ware in Kalkwasser ein und beläßt darin einige Zeit.After boiling for about three hours, this is not filtered, if necessary Salt out the filtrate and carefully remove the deposited chromium compound of the dye dried. -To dye the cotton z. B. 100 parts of the same with 3 parts the chromium compound of the above dye in the presence of Glauber's salt or common salt, for example dyed hot for one hour, or handled for several hours at normal temperature, rinses briefly, goes with the so colored goods in lime water and leaves some in it Time.
