Description
Verfahren zur Herstellung egaler Färbungen Unter dem Namen Pad-Steam ist seit einiger Zeit ein Verfahren zur Herstellung von Färbungen auf Geweben mit Hilfe von Küpenfarbstoffen bekannt. Bei diesem Verfahren wird das Gewebe durch eine wäßrige Suspension eines feinverteilten Küpenfarbstoffes geführt, danach abgequetscht und getrocknet. Sodann durchläuft es ein Bad, das Alkali, ein Reduktionsmittel und gegebenenfalls noch eine geringe Menge des Farbstoffes, mit dein es imprägniert wurde, enthält. Nach erneutemAbquetschen wird das Gewebe gedämpft, wobei der darauf befindliche Farbstoff reduziert und fixiert wird. Hieran schließen sich in üblicher Weise Oxydation und Fertigbehandlung an. Dieses Färbeverfahren bietet in der Praxis zuweilen Schwierigkeiten, da die Reduktion des Farbstoffes, insbesondere bei tiefen Färbungen, längere Zeit beansprucht, so daß man entweder mit einem größeren Dämpfer oder einer geringeren Durchlaufgeschwindigkeit arbeiten muß.Process for the production of level dyeings Under the name Pad-Steam has been a process for producing dyeings on fabrics with for some time The help of vat dyes is known. In this procedure, the tissue is passed through a aqueous suspension of a finely divided vat dye out, then squeezed off and dried. Then it goes through a bath, the alkali, a reducing agent and possibly a small amount of the dye with which it is impregnated contains. After squeezing again, the fabric is steamed, with the on top of it present dye is reduced and fixed. This is followed by the usual Instruct oxidation and final treatment. This staining process offers in practice sometimes difficulties, since the reduction of the dye, especially at deep Dyeings take a long time, so you can either use a larger damper or a lower throughput speed must work.
Man hat versucht, diese Schwierigkeit zu überwinden, indem man die Küpenfarbstoffe sehr fein gemahlen hat. Der Zustand der sehr feinen Verteilung, der im folgenden als »feinstgemahlen« oder »feinstverteilt« bezeichnet wird, ist dadurch charakterisiert, daß die Farbstoffe die Eigenschaft besitzen., in wäßriger Suspension zusammen mit dem Wasser durch ein Filter zu laufen und beim Auftropfen auf Filterpapier oder Stoffproben dieses Material anzufärben, soweit der Tropfen sich darin verteilt. Es ist zwar gelungen, durch Anwendung solcher feinstgemahlener Farbstoffe eine schnellere Reduktion zu erreichen.; dafür hat sich aber der Nachteil eingestellt, daß diese Farbstoffe bei ungleichmäßiger Trocknung des Gewebes zum Wandern neigen, wobei sie sich von. den weniger getrockneten zu den stärker getrockneten Stellen hinziehen. Die Färbungen werden daher in solchen Fällen unegal; das Material ist an den schneller getrockneten Partien kräftiger gefärbt als an. den langsamer getrockneten.Attempts have been made to overcome this difficulty by using the Has ground vat dyes very finely. The state of very fine distribution, which is referred to as "finely ground" or "finely divided" in the following characterized in that the dyes have the property., in aqueous Suspension together with the water to run through a filter and when dripping on to dye this material on filter paper or swatches, as far as the drop distributed in it. It has been successful by using such finely ground Dyes to achieve a faster reduction .; but it has the disadvantage set that these dyes for uneven drying of the fabric Tend to wander, taking them away from. the less dried to the more dried Drag spots. The colors are therefore irrelevant in such cases; the material is colored more vividly on the parts that have dried more quickly than on. the slower one dried.
Es ist nun gefunden worden, daß auch bei ungleichmäßiger Trocknung eine egalere Färbung dadurch erreicht werden kann, wenn den Suspensionen der feinstverteilten Küpenfarbstoffe wasserlösliche Alka,lisalze von Stärkeglykolsäuren zugesetzt werden. Die Wirkung tritt bereits bei Zusatz geringer Mengen, beispielsweise von 1 bis 5 g je Liter der Farbstoffsuspension, ein. Durch den Zusatz der stärlceglykolsauren Alkalisalze verlieren die feinstverteilten Küpenfarbstoffe die Eigenschaft, in wäßriger Aufschwemmung beim Auftropfen auf Filterpapier oder Stoffproben zu wandern. Sie bilden auf der Unterlage einen scharf umgrenzten, dichten Fleck, von dem aus das Wasser sich farblos verteilt.It has now been found that even with uneven drying A more even color can be achieved if the suspensions are finely divided Vat dyes water-soluble alkali salts of starch glycolic acids are added. The effect occurs even with the addition of small amounts, for example from 1 to 5 g per liter of the dye suspension. By adding the starch glycolic acids Alkali salts lose the finely divided vat dyes their property of being watery Float when dripped onto filter paper or fabric swatches. she form a well-defined, dense spot on the surface from which the Water spreads colorlessly.
Es ist bekannt, daß viele Küpenfarbstoffpigmente in wäßriger Suspension nach einer gewissen Zeit zum Absitzen neigen. Dieser Nachteil wird durch die Mitverwendung von wasserlöslichen Alkalisalzen von Stärkeglykolsäuren vermieden; die Stabilität der Farbstoffsuspensionen wird erheblich verbessert. Selbst solche Küpenfarbstoffpigmente, die in wäßriger Suspension nach einiger Zeit zur Zusammenballung oder Vergröberung neigen, werden durch den Zusatz der Stärkeglykolate in feinster Verteilung gehalten. Die durch die Zusammenballung bestehende Gefahr der Stippenbildung wird ausgeschaltet.It is known that many vat dye pigments in aqueous suspension tend to settle down after a certain period of time. This disadvantage is caused by the use avoided from water-soluble alkali salts of starch glycolic acids; the stability the dye suspensions is considerably improved. Even such vat pigments those in aqueous suspension to agglomeration or coarsening after some time tend to be kept in fine distribution by adding starch glycolates. The risk of speck formation caused by the agglomeration is eliminated.
Dieses Verhalten der Stärkeglykolate ist um so überraschender, als die chemisch ähnlich gebauten Salze der Celluloseglykolsäure diese Eigenschaften nicht aufweisen. Als ein weiterer Vorteil des Zusatzes von Stärkeglykolaten hat sich noch eine bessere Farbstoffausnutzung ergeben. Ferner zeichnen sich die Stärkeglykolate auch durch eine besonders leichte Auswaschbarkeit.nach dem Färben aus.This behavior of the starch glycolates is all the more surprising the chemically similar salts of cellulose glycolic acid have these properties do not exhibit. As has another benefit of adding starch glycolates even better dye utilization result. The starch glycolates are also notable also because it is particularly easy to wash out after dyeing.
Die für diesen Zweck benötigten Stärkeglykolate können in bekannter Weise durch Umsatz von Stärke mit Alkali und Chloressigsäure in Gegenwart oder Abwesenheit von Lösungsmitteln gewonnen werden. Insbesondere haben sich solche Stärkeglykolate als brauchbar erwiesen., die mehr als 0,5 Mol Glykolsäure auf 1 Mol Glukoseeinheit gebunden enthalten.The starch glycolates required for this purpose can be used in a known manner Way by reacting starch with alkali and chloroacetic acid in the presence or absence can be obtained from solvents. In particular, such starch glycolates have been found Proven to be useful. That is more than 0.5 mole of glycolic acid per 1 mole of glucose unit bound included.
Beispiel Man löst 2 g stärkeglykolsaures Natrium in 1 1 Wasser und setzt 10 g des durch Kondensation von 1, 4, 5, 8-Naphthalintetracarbonsäure mit 1, 2-Diaminobenzol erhältlichen, Farbstoffs (cis-Form) zu. Ein. mit dieser Suspension geklotztes Gewebe trocknet unter gleichmäßiger Verteilung des Farbstoffes auf und gibt bei der anschließendem, Reduktion und Fixierung eine egale Färbung. Die Farbstoffausgiebigkeit dieser Suspension ist um etwa 20 %. höher als bei Abwesenheit von Stärkeglykolat.EXAMPLE 2 g of sodium starch glycolate are dissolved in 1 l of water and sets 10 g of the by condensation of 1, 4, 5, 8-naphthalenetetracarboxylic acid with 1, 2-diaminobenzene available, dye (cis form) too. A. with this suspension Padded fabric dries up and the dye is evenly distributed gives in the subsequent, reduction and fixation a level Coloring. The dye yield of this suspension is around 20%. higher than in the absence of starch glycolate.
