Description

Verfahren zum Fixieren basischer Farbstoffe auf Baumwolle. Es wurde die bemerkenswerte Beobachtung gemacht, daß die Schweflungsprodukte des Phenols, seiner Derivate und Substitutionsprodükte, wie Kresole, Chlorphenole u. a., sich leicht auf Baumwolle fixieren lassen und so geeignet sind, basische Farbstoffe waschecht zu fixieren. Sie wirken hier als Tanninersatz. Die Färbungen sind wasch- und lichtechter als die auf Tannin erhaltenen.Process for fixing basic dyes on cotton. It was made the remarkable observation that the sulfur products of phenol, its derivatives and substitution products, such as cresols, chlorophenols and others Can easily be fixed on cotton and so are suitable, alkaline dyes are washable to fix. They act here as a tannin substitute. The colors are washable and lightfast than those obtained on tannin.

Beispiel. 26 Gewichtsteile o-Chlorphenol werden in 5o Gewichtsteilen Wasser mit der zur Überführung in das Natriumsalz erforderlichen Menge Natronlauge gelöst und mit einer Lösung, die 6o Gewichtsteile kristallisiertes Schwefelnatrium und 24 Gewichtsteile Schwefel in i3o Gewichtsteilen Wasser enthält, versetzt. Hierzu werden dann 6 Gewichtsteile Schwefel zugefügt und 15 Stunden unter Rückfluß zum Kochen erhitzt. Man läBt erkalten,, verdünnt mit der doppelten, Menge Wasser und fällt reit verdünnter Säure, bis der Auslauf einer auf Filtrierpapier gestrichenen Probe farblos geworden ist. Das abgeschiedene hellgelbe Reaktionsprodukt wird abgesaugt und gut gewaschen. Es kann in: dieser Form direkt verwendet Werden. Es löst sich beim. Erwärmen mit verdünnter Natronlauge, ebenso in Schwefelnatrium, leicht mit gelber Farbe auf und wird durch Säure"äls fast weiße voluminöse Masse wieder ausgefällt.Example. 26 parts by weight of o-chlorophenol are used in 50 parts by weight Water with the amount of sodium hydroxide solution required to convert it into the sodium salt dissolved and with a solution containing 60 parts by weight of crystallized sodium sulphide and contains 24 parts by weight of sulfur in 130 parts by weight of water. For this 6 parts by weight of sulfur are then added and refluxed for 15 hours Cooking heated. Allow to cool, dilute with twice the amount of water and falls with dilute acid until the spout is coated on filter paper Sample has become colorless. The deposited pale yellow reaction product is filtered off with suction and washed well. It can be used directly in: this form. It dissolves at the. Warm up with dilute caustic soda, also in sodium sulphide, lightly with yellow in color and is precipitated again by acid as an almost white voluminous mass.

Analoge Körper erhält man, wenn man statt o-Chlorphenol die p-Verbindungen, Phenol selbst, die Kresole, Di- und Polychlor- oder die entsprechenden Bromplhenole verwendet.Analogous bodies are obtained if, instead of o-chlorophenol, the p-compounds, Phenol itself, the cresols, di- and polychlorophenols or the corresponding bromophenols used.

Das aus o-Chlorph.enol nach obigem Beispiel hergestellte Produkt wird in Natronlauge gelöst. Die Baumwolle wird mit 5 Prozent dieses Produkts (auf Trockensubstanz berechnet) bei go ° eine Stunde lang unter Zusatz von 40 Prozent Kochsalz gebeizt. Es wird abgewunden, verhängt, gespült, mit Essigsäure angesäuert und nochmals gespült. Sodann wird -mit basischen Farbstoffen wie üblich gefärbt.The product made from o-Chlorph.enol according to the above example is dissolved in sodium hydroxide solution. The cotton is made with 5 percent of this product (on dry matter calculated) pickled at go ° for one hour with the addition of 40 percent table salt. It is unwound, draped, rinsed, acidified with acetic acid and rinsed again. It is then colored with basic dyes as usual.

Das aus p-Kresol durch Verschmelzen mit Schwefel. und Schwefelnatrium hergestellte Produkt wird in, Schwefelnatriumlösung gelöst. Die Baumwolle wird mit B. Prozent des Körpers bei go ° unter Zusatz von. 3 Prozent Soda und 40 Prozent kristallisiertem Glaubersalz i Stunde lang behandelt. Es wird abgewunden,-verhängt, mit Essigsäure abgesäuert und gut gespült. Sodann wird mit basischen Farbstoffen, wie üblich gefärbt.That from p-cresol by fusing it with sulfur. and sulfur sodium The manufactured product is dissolved in sodium sulphide solution. The cotton comes with B. Percentage of the body at go ° with the addition of. 3 percent soda and 40 percent treated with crystallized Glauber's salt for 1 hour. It is wound down, imposed, acidified with acetic acid and rinsed well. Then with basic dyes, colored as usual.

Es ist bemerkenswert, daß bei diesem Verfahren die benutzten basischen Farbstoffe; wie Rhodamin B extra, Methylviolett B, Auramin 0 und andere, dieselben Nuancen zeigen wie die nach dem Tanninverfahren hergestellten.It is noteworthy that in this process the basic Dyes; like Rhodamine B extra, methyl violet B, auramine 0 and others, the same Nuances show like those made by the tannin process.
