Description
Schwefelfarbstoffpasten Die bisher aus Schwefelfarbstoffen mit Hilfe von Homogenisierungsmitteln, wie Melasse, Stärke usw., und unter etwaigem Zusatz von Schwefelnatrium herstellbaren Pasten haben sich im allgemeinen nicht bewährt. Sie waren teils zu dünnflüssig, teils ließen sie die ihnen zugesetzten Salze bei der Aufbewahrung auskristallisieren, womit eine Entmischung und gegebenenfalls eine physikalische Veränderung der Paste verbunden war. Auch trat, zumal bei Temperaturschwankungen, leicht Gärung ein, die ein Nachlassen der Farbkraft zur Folge hatte. Nicht unerwähnt soll schließlich auch der. solchen Pasten eigentümliche unangenehme Geruch bleiben.Sulfur Dye Pastes The so far made from sulfur dyes with the help of homogenizing agents, such as molasses, starch, etc., and with any additives Pastes that can be prepared from sodium sulphide have generally not proven successful. Some of them were too thin, and some left the salts added to them crystallize out of storage, causing a separation and possibly a physical change in the paste was associated. Also occurred, especially with temperature fluctuations, slight fermentation, which resulted in a decrease in the strength of the color. Not unmentioned should that too, after all. such pastes retain their peculiar unpleasant odor.
Alle diese Übelstände lassen sich, wie gefunden wurde, vermeiden und einwandfreie, geruchlose, haltbare Pasten jeder beliebigen Konsistenz herstellen, wenn man den mit Schwefelnatrium angerührten Schwefelfarbstoffen, die man z. B. unmittelbar aus den Fabrikationsschmelzen oder den isolierten Farbstoffen gewinnen kann, einen Zusatz von Harzseifen oder ihren Lösungen als Pastengrundlage gibt. Die so erhältlichen homogenen Pasten, denen man noch bei der Herstellung weitere für den Färbeprozeß erforderliche Mengen Schwefelnatrium hinzufügen kann, lassen sich unmittelbar oder nach Zusatz von Steinsalz oder Natriumsulfat in stets gleichbleibender Färbekraft zum Färben verwenden.It has been found that all of these evils can be avoided and produce flawless, odorless, durable pastes of any consistency, if one of the sulfur dyes mixed with sodium sulphide, which one z. B. Obtain directly from the production melts or the isolated dyes can, an addition of resin soaps or their solutions as a paste base. The homogeneous pastes obtainable in this way, which you can still use in the production can add amounts of sodium sulphide required for the dyeing process immediately or after the addition of rock salt or sodium sulphate in an always constant Use dyeing power for dyeing.
B eispiel roo g des nach der Patentschrift 127 835 hergestellten Schwefelfarbstoffes werden mit der zum Färben notwendigen Menge Schwefelnatrium (25o bis 300 g kristallisiert) und Alkali (?5 bis 50 g Natriumhydroxydlösung von 356 B6) verrührt und unter Zusatz von 1z bis r5. g Harzseife auf die geforderte Konsistenz eingestellt.Example roo g of the sulfur dye prepared according to patent specification 127 835 are stirred with the amount of sodium sulfur (25o to 300 g crystallized) and alkali (? 5 to 50 g sodium hydroxide solution of 356 B6) necessary for dyeing and with the addition of 1z to r5. g resin soap adjusted to the required consistency.
Eine derart hergestellte Paste ist selbst bei ungünstigen Temperaturverhältnissen monatelang haltbar und kann unmittelbar zum Färben verwendet werden.A paste produced in this way is even under unfavorable temperature conditions Lasts for months and can be used immediately for dyeing.
