Description
Verfahren zum Färben von Kunstseide mit Schwefelfarbstoffen. Zusatz zum Patent q.o8q.o4. Schwefelfarbstoffe werden nach den bisher üblichen Vorschriften auf Kunstseide aus dem Schwefelnatriumbade unter Zusatz von Soda und Kochsalz bei einer Temperatur von 4o bis 6o° C gefärbt. Das Verfahren hat sich jedoch nicht recht eingebürgert, da die Kunstseide durch das Schwefelnatriumbad infolge seiner starken Alkalität leidet.Process for dyeing rayon with sulfur dyes. additive for patent q.o8q.o4. Sulfur dyes are made according to the usual regulations on artificial silk from the sulphurous sodium bath with the addition of soda and table salt at a temperature of 4o to 6o ° C. However, the procedure was not right naturalized as the artificial silk by the sulfur sodium bath as a result of its strong Alkalinity suffers.
Es hat sich nun gezeigt, daß man an Stelle des Schwefelnatriumbades mit großem Vorteil eine Hydrosulfitküpe anwendet, die als Alkali anstattNatronlauge und anderen kaustischen Alkalien Alkalicarbonate enthält und die sich gegenüber dem Schwefelnatriumbade durch einen wesentlich geringeren Gehalt des Färbebades an Alkali auszeichnet. Man verküpt zu diesem Zwecke die Schwefelfarbstoffe bei etwa 5o° C in einem Bade, das Hvdrosulfit und Soda und evtl. noch öle oder Seifen, wie Türkonö1, Monopolseife usw., enthält, das aber frei von kaustischem Alkali ist.It has now been shown that instead of the sodium sulphide bath Use a hydrosulphite vat with great advantage, which is used as an alkali instead of sodium hydroxide and other caustic alkalis containing alkali carbonates and which oppose each other the sodium sulphide bath due to the significantly lower content of the dyebath excels in alkali. For this purpose, the sulfur dyes are pooled at about 50 ° C in a bath, the hot sulfite and soda and possibly oils or soaps, like Türkonö1, monopole soap, etc., which is free of caustic alkali.
Diese neue Färbeweise greift die Faser weniger an als das bisher übliche Verfahren, die Faser bleibt glatt und geschmeidig, während sie im Schwefelnatriumbade einen ! rauhen, strohigen Griff erhält. Besonders auffallend ist der Effekt bei der Bemberg-Adler-Kunstseide, doch ist das Verfahren für alle Arten von Kunstseide und Stapelfasern mit Vorteil anwendbar. Beispiel: 500 g Thiogenschwarz MM conc. oder eines anderen Schwefelfarbstoffes werden mit 500 g Soda und a5o bis 300 g Hydrosulfit conc. Pulver unter Zusatz von i kg Kochsalz und 250 g Türkonöl in ioo 1 Wasser bei 5o° C verküpt und darin 5 kg Kunstseide "f, Stunde bei 5o bis 6o° C gefärbt. Nach dem Färben wird gespült und, wenn nötig, aviv iert.This new method of dyeing attacks the fiber less than the previous method, the fiber remains smooth and supple while it is bathed in sulfur-sodium! receives a rough, straw-like grip. The effect is particularly noticeable with Bemberg-Adler artificial silk, but the process can be used with advantage for all types of artificial silk and staple fibers. Example: 500 g Thiogen Black MM conc. or another sulfur dye are mixed with 500 g of soda and a5o to 300 g of hydrosulfite conc. Powder with the addition of 1 kg of table salt and 250 g of Türkonöl vat in 100 1 of water at 50 ° C. and dyed 5 kg of artificial silk in it for an hour at 50 to 60 ° C. After the dyeing, it is rinsed and, if necessary, finished off.
