Definitions
- the present invention relates to a uniform new method for fiber and surface level dyeing of natural polyamide materials with anionic wool dyes of different dye classes in light to dark shades from an aqueous liquor, regardless of the depth of color of the dyeing and regardless of the dye class used for natural polyamide material with a gentle pH Value is dyed, the dyebath is practically completely pulled out and the dyeing shows good overall fastness properties, in particular good wet fastness properties and good light fastness, and the material dyed by the new process.
- a disadvantage of the dyeing processes for natural polyamides which have been customary hitherto is that dyeing at different pH values is necessary both in order to achieve light and dark shades and when using dyes from different dye classes. It is known from the literature, for example, that acid dyes with a good leveling agent at a pH of 2 to 3.5, acid fast dyes at a pH of 4 to 5, highly acid dyes at a pH of 6 to 7.1, 1: 2 -Metal complex dyes without sulfo groups at a pH of 5 to 7.1: 1: 2 metal complex dyes with sulfo groups at a pH of 4 to 7.1: 1: 1 metal complex dyes at a pH of 1.9 to 2.8 and reactive dyes be dyed at a pH of 4.5 to 7.
- a further disadvantage of the dyeing processes customarily used up to now for wool is that auxiliaries which are matched to the respective dye class are used to equalize the affinity differences of the wool (dichroism), since the dichroism depends on the hydrophilicity of the dyes used; i.e. the auxiliaries used in the usual dyeing processes cannot be applied to all dye classes with equally good success. Irregularities in color and shade occur in particular when hydrophilic dyes are combined with more hydrophobic dyes. In many cases, the surface-level coloring of natural polyamide materials is also unsatisfactory.

Description
Die vorliegende Erfindung betrifft ein einheitliches neues Verfahren zum faser- und flächenegalen Färben von natürlichen Polyamidmaterialien mit anionischen Wollfarbstoffen unterschiedlicher Farbstoffklassen in hellen bis dunklen Farbtönen aus wässriger Flotte, wobei unabhängig von der Farbtiefe der Färbung und unabhängig von der verwendeten Farbstoffklasse bei für natürliches Polyamidmaterial faserschonendem pH-Wert gefärbt wird, das Färbebad praktisch vollständig ausgezogen wird und die Färbung gute Gesamtechtheiten, insbesondere gute Nassechtheiten und gute Lichtechtheit zeigt, sowie das nach dem neuen Verfahren gefärbte Material.The present invention relates to a uniform new method for fiber and surface level dyeing of natural polyamide materials with anionic wool dyes of different dye classes in light to dark shades from an aqueous liquor, regardless of the depth of color of the dyeing and regardless of the dye class used for natural polyamide material with a gentle pH Value is dyed, the dyebath is practically completely pulled out and the dyeing shows good overall fastness properties, in particular good wet fastness properties and good light fastness, and the material dyed by the new process.
Nachteil der bisher üblichen Färbeverfahren für natürliche Polyamide ist, dass sowohl zur Erzielung heller und dunkler Farbtöne, als auch bei Verwendung von Farbstoffen aus verschiedenen Farbstoffklassen, bei unterschiedlichen pH-Werten gefärbt werden muss. So ist aus der Literatur bekannt, dass gut egalisierende Säurefarbstoffe bei einem pH-Wert von 2 bis 3,5, walkechte Säurefarbstoffe bei einem pH-wert von 4 bis 5, hochwalkechte Säurefarbstoffe bei einem pH-Wert von 6 bis 7, 1:2-Metallkomplexfarbstoffe ohne Sulfogruppen bei einem pH-Wert von 5 bis 7, 1:2 Metallkomplexfarbstoffe mit Sulfogruppen bei einem pH-Wert von 4 bis 7, 1:1-Metallkomplexfarbstoffe bei einem pH-Wert von 1,9 bis 2,8 und Reaktivfarbstoffe bei einem pH-Wert von 4,5 bis 7 gefärbt werden.A disadvantage of the dyeing processes for natural polyamides which have been customary hitherto is that dyeing at different pH values is necessary both in order to achieve light and dark shades and when using dyes from different dye classes. It is known from the literature, for example, that acid dyes with a good leveling agent at a pH of 2 to 3.5, acid fast dyes at a pH of 4 to 5, highly acid dyes at a pH of 6 to 7.1, 1: 2 -Metal complex dyes without sulfo groups at a pH of 5 to 7.1: 1: 2 metal complex dyes with sulfo groups at a pH of 4 to 7.1: 1: 1 metal complex dyes at a pH of 1.9 to 2.8 and reactive dyes be dyed at a pH of 4.5 to 7.
Dem pH-Wert des Färbebades kommt beim Färben von natürlichen Polyamidmaterialien, insbesondere beim Färben von Wolle, neben der Färbetemperatur und der Färbedauer eine entscheidende Bedeutung zu, da besonders die Wolle sowohl im stark sauren wie im alkalischen pH-Bereich stark angegriffen wird.When dyeing natural polyamide materials, especially when dyeing wool, the pH value of the dye bath comes next to that The dyeing temperature and the dyeing time are of crucial importance, since wool in particular is severely attacked both in the strongly acidic and in the alkaline pH range.
Ein weiterer Nachteil der bisher üblichen Färbeverfahren speziell für Wolle ist, dass zum Egalisieren der Affinitätsunterschiede der Wolle (Dichroismus) auf die jeweilige Farbstoffklasse abgestimmte Hilfsmittel verwendet werden, da der Dichroismus von der Hydrophilie der verwendeten Farbstoffe abhängt; d.h. die in den bisher üblichen Färbeverfahren eingesetzten Hilfsmittel sind nicht mit gleich gutem Erfolg auf alle Farbstoffklassen anwendbar. Insbesondere bei der Kombination von hydrophilen Farbstoffen mit hydrophoberen Farbstoffen treten Unregelmässigkeiten im Farbton und in der Nuance auf. Vielfach ist ferner die flächenegale Durchfärbung natürlicher Polyamidmaterialien unbefriedigend.A further disadvantage of the dyeing processes customarily used up to now for wool is that auxiliaries which are matched to the respective dye class are used to equalize the affinity differences of the wool (dichroism), since the dichroism depends on the hydrophilicity of the dyes used; i.e. the auxiliaries used in the usual dyeing processes cannot be applied to all dye classes with equally good success. Irregularities in color and shade occur in particular when hydrophilic dyes are combined with more hydrophobic dyes. In many cases, the surface-level coloring of natural polyamide materials is also unsatisfactory.
Ueberraschenderweise wurde nun ein einheitliches Verfahren gefunden, das die genannten Nachteile und Schwierigkeiten nicht aufweist und welches erlaubt auf einfache Art und Weise natürliches Polyamid unabhängig von der gewünschten Farbtiefe und unabhängig vom verwendeten Farbstofftyp und sogar bei Verwendung von Gemischen verschiedener Farbstofftypen im faserschonenden pH-Bereich von 4,5 bis 5,5 zu färben.Surprisingly, a uniform process has now been found which does not have the disadvantages and difficulties mentioned and which allows natural polyamide in a simple manner regardless of the desired depth of color and regardless of the type of dye used and even when using mixtures of different types of dye in the fiber-protecting pH range of Color 4.5 to 5.5.
Gegenstand der vorliegenden Erfindung ist somit ein Verfahren zum faser- und flächenegalen Färben von Fasermaterial aus natürlichen Polyamiden mit Farbstoffen oder Farbstoffmischungen in Gegenwart eines Hilfsmittelgemisches, welches dadurch gekennzeichnet ist, dass man zum Färben dieser Materialien eine wässrige Flotte verwendet, welche mindestens einen anionischen Wollfarbstoff, der unter den definierten Färbebedingungen bei 1/1 Richttyptiefe einen Ausziehgrad von mindestens 95 % aufweist, und ein Hilfsmittelgemisch bestehend aus einer anionischen Verbindung der Formel

In general, amounts of 0.001 to 10 percent by weight, based on the material to be dyed, of one or more dyes have proven to be advantageous.
Unter 1/1-Richttyptiefe ist die gemäss DIN (Deutsche-Industrie-Norm) 54000 bezeichnete Farbtiefe 1/1 zu verstehen.1/1 standard depth is understood to mean the color depth 1/1 designated in accordance with DIN (German Industry Standard) 54000.
Ein Ausziehgrad von mindestens 95 % bedeutet, dass weniger als 5 % der in dem erfindungsgemässen Verfahren eingesetzten Farbstoffmenge nach dem Färben im Bad zurückbleiben.A degree of exhaustion of at least 95% means that less than 5% the amount of dye used in the process according to the invention remain in the bath after dyeing.

The fiber material can be in a wide variety of forms, such as a loose material, drawstring, yarn and piece goods or as a carpet.
Das erfindungsgemässe Verfahren weist gegenüber den bekannten Verfahren für Fasermaterial aus natürlichen Polyamiden neben den bereits genannten noch folgende Vorteile auf. Das so unter einheitlichen Färbebedingungen gefärbte Material zeichnet sich in der Weiterverarbeitung wie z.B. dem Spinnen durch gleichartiges Verhalten aus. Die erhaltenen Färbungen zeichnen sich zudem durch gute Gesamtechtheiten, insbesondere gute Licht- und Nassechtheiten aus, und sie sind unabhängig vom gewählten Farbton und sogar unabhängig vom gewählten Gemisch an verschiedenen Farbstofftypen faser- und flächenegal gefärbt. Ein weiterer wesentlicher Vorteil besteht darin, dass die Farbstoffe praktisch vollständig aufgenommen werden. Nach beendetem Färben sind die Färbebäder vollständig bzw. nahezu vollständig ausgezogen, wodurch mehrmalige Verwendung der aufgeheizten wässrigen Flottenlösung ermöglicht wird, was weniger Energie erfordert.The method according to the invention has the following advantages over the known methods for fiber material made from natural polyamides in addition to the already mentioned. The material so dyed under uniform dyeing conditions excels in further processing such as spinning through similar behavior. The dyeings obtained are also notable for good overall fastness properties, in particular good light and wet fastness properties, and they are dyed regardless of the color shade and even regardless of the selected mixture of different types of dyes, regardless of fiber and area. Another important advantage is that the dyes are almost completely absorbed. After dyeing is complete, the dye baths are completely or almost completely drawn out, which enables repeated use of the heated aqueous liquor solution, which requires less energy.
