30 Zum Färben in wässrigen Flotten verwendet man die wasserunlöslichen Farbstoffe gemäss vorliegender Erfindung zweckmässig in feinverteilter Form und färbt unter Zusatz von Dispergiermitteln, wie Sulfitcelluloseablauge oder synthetischen Waschmitteln, oder einer Kombination verschiedener Netz- und 35 Dispergiermittel. In der Regel ist es zweckmässig, die zu verwendenden Farbstoffe vor dem Färben in ein Färbepräparat überzuführen, das ein Dispergiermittel und feinverteilten Farbstoff in solcher Form enthält, dass beim Verdünnen der Farbstoffpräparate mit Wasser eine feine Dispersion entsteht. Solche 40 Farbstoffprärapate können in bekannter Weise, zum Beispiel durch Vermählen des Farbstoffes in trockener oder nasser Form mit oder ohne Zusatz von Dispergiermitteln beim Mahlvorgang erhalten werden. 30 For dyeing in aqueous liquors, the water-insoluble dyes according to the present invention are expediently used in finely divided form and dyed with the addition of dispersants, such as sulfite cellulose waste liquor or synthetic detergents, or a combination of different wetting agents and 35 dispersants. As a rule, it is expedient to convert the dyes to be used before dyeing into a dye preparation which contains a dispersant and finely divided dye in such a way that a fine dispersion is formed when the dye preparations are diluted with water. Such 40 dye prepolymers can be obtained in a known manner, for example by grinding the dye in dry or wet form with or without the addition of dispersants during the grinding process.
Zur Erreichung starker Färbungen auf Polyäthylentere-45 phthalatfasern erweist es sich als zweckmässig, dem Färbebad ein Quellmittel zugegeben, oder aber den Färbeprozess unter Druck bei Temperaturen über 100 °C, beispielsweise bei 130 °C, durchzuführen. Als Quellmittel eignen sich aromatische Carbonsäuren, beispielsweise Salicylsäure, Phenole, wie bei-50 spielsweise o- oder p-Oxydiphenyl, aromatische Halogenverbindungen, wie o-Dichlorbenzol oder Diphenyl. In order to achieve strong dyeings on polyethylene terephthalate fibers, it has proven expedient to add a swelling agent to the dye bath or to carry out the dyeing process under pressure at temperatures above 100 ° C., for example at 130 ° C. Suitable swelling agents are aromatic carboxylic acids, for example salicylic acid, phenols, such as, for example, o- or p-oxydiphenyl, aromatic halogen compounds, such as o-dichlorobenzene or diphenyl.
Zur Thermofixierung des Farbstoffes wird das foulardierte Polyestergewebe, zweckmässig nach vorheriger Trocknung, z.B. in einem warmen Luftstrom, auf Temperaturen von über 55 100 °C, beispielsweise zwischen 180 bis 210 °C, erhitzt. To heat-fix the dye, the padded polyester fabric is expedient, after drying, e.g. heated in a warm air stream to temperatures above 55 100 ° C, for example between 180 to 210 ° C.
Die gemäss vorliegendem Verfahren erhaltenen Färbungen können einer Nachbehandlung unterworfen werden, beispielsweise durch Erhitzen mit einer wässerigen Lösung eines ionenfreien Waschmittels. The dyeings obtained according to the present process can be subjected to an aftertreatment, for example by heating with an aqueous solution of an ion-free detergent.
60 Anstatt durch Imprägnieren können gemäss vorliegendem Verfahren die angegebenen Farbstoffe auch durch Bedrucken aufgebracht werden. Zu diesem Zweck verwendet man z.B. eine Druckfarbe, die neben den in der Druckerei üblichen Hilfsmitteln, wie Netz- und Verdickungsmitteln, den feindispergierten 65 Farbstoff enthält. 60 Instead of impregnation, the specified dyes can also be applied by printing in accordance with the present process. For this purpose, e.g. a printing ink that contains the finely dispersed dye in addition to the auxiliaries commonly used in printing, such as wetting and thickening agents.
Nach dem vorliegenden Verfahren erhält man kräftige Färbungen und Drucke von guten Echtheiten. The present process gives strong dyeings and prints of good fastness properties.
Gleichfalls kräftige Färbungen erzielt man bei Applikation Likewise strong stains are achieved when applied

The polymer to be colored is expediently mixed with the dye in the form of powders, granules or chips, as a finished spinning solution or in the molten state with the dye, which is introduced in the dry state or in the form of a dispersion or solution in an optionally volatile solvent. After homogeneous distribution of the dye in the solution or melt of the polymer, the mixture is converted into fibers, yarns, monofilaments, films, etc. in a known manner by casting, pressing or extruding.
