Description
Verfahren zum Färben von Wolle mit Küpenfarbstoffen auf mechanischen Färbe-Apparaten. Beim Färben von Küpenfarbstoffen auf Wolle verfährt man bekanntlich in der Weise, daß nach beendigter Färbung die `''olle zwecks Oxydation abgequetscht und an der Luft liegengelassen wird, oder daß man sie nach dem Abquetschen zur Vergrünung in kaltem Wasser behandelt. In beiden Fällen tritt die Oxvdation des Leukofarbstoffes durch den Sauerstoff der Luft und durch den im Wasser enthaltenen Sauerstoff ein.Method of dyeing wool with vat dyes on mechanical Dyeing apparatus. It is well known that one proceeds when dyeing vat dyes on wool in such a way that after the dyeing is finished, the `` '' olle is squeezed off for the purpose of oxidation and left in the air, or after squeezing them to turn green treated in cold water. In both cases the oxidation of the leuco dye occurs through the oxygen in the air and through the oxygen contained in the water.
Beim Färben auf mechanischen Färbeapparaten können diese Vergrünungsmethoden nicht gut durchgeführt werden, und es tritt dann die Erscheinung ein, daß nach Entfernung der Flotte, sei es durch Absaugen oder Schleudern, die Färbungen ""ersticken" d. h. die Oxydation der Leukofarbstoffe infolge ungenügender Zufuhr von Sauerstoff nicht oder nicht in genügendem Maße eintritt.When dyeing on mechanical dyeing machines, these can cause greening methods are not carried out well, and then the phenomenon occurs that after removal the liquor, be it by suction or centrifugation, the dyeings "" suffocate "" d. H. the oxidation of the leuco dyes as a result of insufficient supply of oxygen does not occur or does not occur to a sufficient extent.
Pumpt man aber durch das im Apparat befindliche ':Material starke :Mengen Wasser hindurch, so wird ein mehr oder weniger großer Anteil des noch als Leukofarbstoff vorhandenen Farbstoffes von der Faser wieder heruntergespült, weil erst der oxydierte Farbstoff fest von der Faser gebunden wird.But if you pump through the ': material in the apparatus : Amounts of water through, a more or less large part of the still as Because leuco dye is present in the fiber, it is washed down again only the oxidized dye is firmly bound by the fiber.
Es ist nun gefunden worden, daß durch Zugabe eines geeigneten Oxydationsmittels, wie Wasserstoffsuperoxyd u. dgl., zur Spülflüssigkeit die Oxydation der auf der Faser befindlichen Leukoverbindung vollkommen und so schnell erfolgt, daß selbst bei der höheren Temperatur, die die Spülflüssigkeit durch Aufnahme der im Material enthaltenen Wärme erhält, nicht mehr wesentliche Mengen des Farbstoffes heruntergewaschen werden, so daß ein genügend sicheres Färben erreicht wird.It has now been found that by adding a suitable oxidizing agent, such as hydrogen peroxide and the like, to the rinsing liquid the oxidation of the The leuco compound located in the fiber takes place completely and so quickly that even at the higher temperature that the rinsing liquid by absorbing the in the material contained heat, no longer washed down substantial amounts of the dye so that a sufficiently reliable dyeing is achieved.
Durch die Oxydation unter Zusatz eines Oxydationsmittels ist es weiterhin möglich, auf mechanischen Färbeapparaten zweizügige Färbungen herzustellen, ohne daß das Material zwischen dem z. und 2. Zug ausgepackt werden muß, um es zu oxydieren. Man kann also auf diese Weise auf loser Wolle, Kammzug usw. in zwei Zügen in wirtschaftlicher Weise arbeiten.It is still through the oxidation with the addition of an oxidizing agent possible to produce two-step dyeings on mechanical dyeing machines without that the material between the z. and 2nd train has to be unpacked in order to oxidize it. In this way you can work on loose wool, tops, etc. in two moves in an economical way Work wisely.
Auch Stranggarn kann nach dem Verfahren in einem der-üblichen Apparate mit Küpenfarbstoffen gefärbt werden. Da keine Luftoxydation mehr erforderlich ist, wie bei der einfachen Wasservergrünung, kann das Material nicht mehr beim Schleudern oder Abquetschen durch ungleichmäßige Oxydation unegal werden.Hank yarn can also be produced in one of the usual apparatuses according to the method colored with vat dyes. Since air oxidation is no longer necessary, As with simple water greening, the material can no longer be spun or being squeezed out by uneven oxidation.
Beispiel: Ein Obermaier-Apparat von'-7 5oo 1 Fassungsvermögen wird mit den Kammzugbobinen (zoo kg Kammzug) beschickt.'Nach dem Netzen der Bobinen mit '\Vasser °vön ' 5o0 beschickt man den Apparat mit z kg Leim, 3 kg Hydrosulfit konz. Pulver,@I 0,5 kg Ammonsulfat und einer Lösung von z2 kg Helindonschwarz R-Küpe fest. Man schaltet die Pumpe ein, gibt nach 15 Minuten weitere o,6 kg Ammonsulfat in verdünnterLösunglangsam hinzu, bis dasBad annähernd neutral reagiert.Example: An Obermaier apparatus with a capacity of'-7500 l will be with the combed bobbins (zoo kg combed). 'After netting the bobbins with '\ Vasser ° vön' 50 the apparatus is charged with z kg of glue, 3 kg of hydrosulphite conc. Powder, @ I 0.5 kg of ammonium sulfate and a solution of 2 kg of Helindon black R-vat solid. Man switches on the pump, after 15 minutes slowly gives a further 0.6 kg of ammonium sulphate in dilute solution until the bathroom reacts almost neutrally.
Nach halbstündiger Färbedauer pumpt man die Flotte in einen Reservebehälter, läßt kaltes Wasser, dem 2 kg Wasserstoffsuperoxyd 3oprozentig zugesetzt sind, in den Apparat laufen und schaltet die Pumpe wieder ein.After half an hour of dyeing, the liquor is pumped into a reserve tank, lets cold water, to which 2 kg of hydrogen peroxide are added 3 percent, in the machine is running and the pump is switched on again.
Nach einer Zirkulationsdauer von io bis 15 Minuten läßt man die Oxydationsflotte ab, spült mit Wasser nach und gibt dem Kammzug in der alten Flotte unter Zusatz von etwas Hvärosulfit konz. Pulver den zweiten Zug. -Zum Schluß vergrünt man ebenso, wie es für den ersten Zug angegeben ist. An Stelle von Wasserstoffsuperoxyd kann auch ein anderes Oxydationsmittel, wie Ammoniumpersulfat, N atriumperborat, Kaliumbichromat usw. benutzt werden.After a circulation time of 10 to 15 minutes, the oxidation liquor is drained off, rinsed with water and added to the top in the old liquor with the addition of a little Hvärosulfit conc. Powder the second puff. -Finally, you green as it is indicated for the first move. Instead of hydrogen peroxide, another oxidizing agent, such as ammonium persulphate, sodium perborate, potassium dichromate, etc., can also be used.
