The process according to the invention is generally carried out at a temperature of e.g. 60 to 130 ° C carried out.
Wenn das zu färbende Material Wolle allein ist, erfolgt die Färbung zweckmässig nach dem Ausziehverfahren, z.B. bei einer Temperatur im Bereich 60 bis 106°C, vorzugsweise 95 bis 98°C. Die Färbedauer kann in Abhängigkeit von den Erfordernissen variieren, beträgt jedoch vorzugsweise 60-120 Minuten.If the material to be dyed is wool alone, the dyeing is expediently carried out the pull-out process, e.g. at a temperature in the range of 60 to 106 ° C, preferably 95 to 98 ° C. The dyeing time can vary depending on the requirements, however, it is preferably 60-120 minutes.
Die Färbungen der Polyester/Wolle-Mischfasermaterialien erfolgen mit Vorteil einbadig aus wässriger Flotte nach dem Ausziehverfahren.

Das Färben der Polyester/Wolle-Mischfasermaterialien kann so durchgeführt werden, dass man das Färbegut zuerst mit dem Wollschutzmittel und gegebenenfalls dem Carrier behandelt und anschliessend färbt. Man kann auch so vorgehen, dass man das Färbegut gleichzeitig mit dem Wollschutzmittel, den Farbstoffen und gegebenenfalls Hilfsmitteln behandelt. Vorzugsweise geht man mit dem Textilmischfasermaterial in eine Flotte ein, die das Wollschutzmittel und gegebenenfalls weitere übliche Hilfsmittel enthält und eine Temperatur von 40-50°C aufweist, und behandelt das Material 5 bis 15 Minuten bei dieser Temperatur. Danach erhöht man die Temperatur auf ca. 60 bis 70°C, gibt den Farbstoff zu, erhitzt langsam auf die Färbetemperatur und färbt dann ca. 20 bis 60, vorzugsweise 30 bis 45 Minuten, bei dieser Temperatur. Am Schluss wird die Flotte auf etwa 60°C abgekühlt und das gefärbte Material wie üblich aufgearbeitet.The dyeing of the polyester / wool mixed fiber materials can be carried out in such a way that the first thing to be dyed is the wool preservative and, if necessary, the carrier treated and then colored. You can also proceed in such a way that you dye the material at the same time with the wool protection agent, the dyes and, if necessary, auxiliaries treated. The textile mixed fiber material is preferably added to a fleet, which contains the wool protection agent and possibly other conventional auxiliaries and a Has temperature of 40-50 ° C, and treated the material for 5 to 15 minutes Temperature. Then you raise the temperature to about 60 to 70 ° C, give the dye , heats up slowly to the dyeing temperature and then dyes about 20 to 60, preferably 30 up to 45 minutes at this temperature. At the end the fleet is heated to around 60 ° C cooled and the colored material worked up as usual.
Mittels des erfindungsgemässen Verfahrens ist es möglich, Wolle oder insbesondere Wolle/Polyester-Fasergemische bei hoher Temperatur unter einwandfreiem Schutz des Wollanteils, d.h. unter Erhaltung der wichtigen, fasertechnologischen Eigenschaften der Wolle, wie Reissfestigkeit, Berstbeständigkeit und Dehnung, zu färben. Hervorzuheben ist weiterhin, dass der Polyesteranteil bei Mischgeweben keine Angilbung zeigt.By means of the method according to the invention it is possible to use wool or in particular Wool / polyester fiber mixtures at high temperature with perfect protection of the Wool share, i.e. while maintaining the important fiber-technological properties of the Color wool, such as tear resistance, burst resistance and stretch. It should be emphasized furthermore that the proportion of polyester in mixed fabrics shows no yellowing.
Ein weiterer Vorteil des erfindungsgemässen Verfahrens betrifft die Verringerung des Settings, die durch die Anwesenheit einer Verbindung der Formel (1) im Färbebad erreicht wird. Als Setting bezeichnet man eine unerwünschte während des Färbeprozesses auftretende Fixierung der Wollfasern, welche durch Umordnung der in der Wolle enthaltenen Disulfid-Brücken verursacht wird. Solche unerwünschten Fixierungen können sich z.B. in einer Deformation (Verflachung) der Wollgarne auf Spulen, einer Kompaktierung der Wollfasern sowie in einem Verlust des Volumens der Wolle äussern.Another advantage of the method according to the invention relates to the reduction of the Settings achieved by the presence of a compound of formula (1) in the dye bath becomes. A setting is an unwanted one during the dyeing process fixation of the wool fibers, which is caused by rearrangement of the wool contained disulfide bridges is caused. Such undesirable fixations can e.g. in a deformation (flattening) of the wool yarns on bobbins, one Compacting the wool fibers as well as expressing a loss in the volume of the wool.
Der Antisetting-Effekt eines Wollschutzmittels kann z.B. in Anlehnung an A.M. Wemys und M.A. White, Proc. Ind. Japan-Australia, Joint Symp. on objective measurement, Kyoto (1985), Seite 165, bestimmt werden, indem man Rondelle aus Woll-Testgewebe ausstanzt, in der Mitte faltet und am Rand zusammennäht. Die Prüflinge werden dann in gepresstem Zustand in Gegenwart des Wollschutzmittels gefärbt, anschliessend die Gewebemuster geöffnet und jeweils ein Faden herausgezogen. Nach einer Erholungsphase in warmem Wasser wird der Winkel der Fäden gemessen. Je mehr sich das vorher zusammengepresste Garn geöffnet hat und um so mehr sich der gemessene Winkel an 180° annähert, um so besser ist der Antisetting-Effekt des Wollschutzmittels. Ein gemessener Winkel von ca. 120 bis 180° und insbesondere 140 bis 180° zeigt einen guten Anti-Setting-Effekt an.The antisetting effect of a wool protection agent can e.g. based on A.M. Wemys and M.A. White, Proc. Ind. Japan-Australia, Joint Symp. On objective measurement, Kyoto (1985), page 165, can be determined by making rondelles from wool test fabric punched out, folded in the middle and sewn together at the edge. The candidates are then in pressed state dyed in the presence of the wool protection agent, then the Fabric pattern opened and one thread pulled out. After a recovery period the angle of the threads is measured in warm water. The more that happened before compressed yarn has opened and the more the measured angle Approaching 180 °, the better the anti-setting effect of the wool protection agent. On measured angle of approx. 120 to 180 ° and in particular 140 to 180 ° shows a good one Anti-setting effect.
