The present invention relates to a method for printing textile fibre materials using water- insoluble colorants, like disperse and vat dyes and pigments, in accordance with the ink-jet printing process.

Ink-jet printing inks and processes have already been used for some time in the textile industry. They make it possible to do without the otherwise customary production of a printing stencil, so enabling considerable savings to be made in both cost and time. In connection with the production of originals, in particular, it is possible to respond to changes within a much shorter time.

Appropriate ink-jet printing inks should in particular have optimum performance

characteristics. In this context mention may be made of characteristics such as viscosity, stability, surface tension and conductivity of the inks that are used. In addition, heightened requirements are placed on the quality of the resulting prints, in terms, for example, of colour strength, fibre-dye bond stability, and wet fastness properties.

A significant number of aqueous inks containing reactive dyes which are suitable for the ink- jet printing of cotton (CO) and other cellulosic fibres are known.

Ink-jet printing of polyester (PES) fibres, however, is less widespread and requires inks based on disperse dyes.

Many attempts have been made to develop efficient processes for printing PES/CO blends. Usually reactive dyes or vat dyes are combined with disperse dyes.

However, the use of such dye mixtures is associated with several drawbacks and it is hardly possible to obtain the same shade and colour depth on the two fibres by this method.

Accordingly, there is a need for an ink-jet printing method for PES/CO blends which works without a combination of reactive and disperse dyes and provides printings exhibiting good washfastness, lightfastness, colour strength and brilliance.

The present invention accordingly relates to a method for printing cellulose or cellulose blend textile fibre material in accordance with the ink-jet printing process, wherein the fibre material in a first step is treated with a liquor containing at least 6 % by weight of an organic solvent having a boiling point >150 °C and an average molecular weight (weight average) M _w > 250 g/mol selected from polyethylene glycol, polypropylene glycol or an ether or ester derivative of polyethylene glycol or polypropylene glycol and subsequently is printed with an aqueous ink comprising at least one water-insoluble colorant which is soluble in hydrophilic organic solvents at elevated temperature,

with the proviso that said solvent contains < 20 % by weight, preferably < 10 % by weight, and in particular < 5 % by weight, of a lactam.

Elevated temperature in this context means a temperature > 60 °C, preferably > 80 °C, and in particular > 100 °C.

The treatment with the organic solvent can be carried out by known methods, for example by an exhaust process or preferably a padding process. The pretreatment liquor containing the water-soluble organic solvent may contain further customary additives, like thickening agents, levelling agents, reduction inhibitors, fixing agents etc.

Preferably the fibre material is dried after the above pretreatment.

The water-insoluble colorant is preferably a vat dye, a solvent dye, a pigment or, in particular, a disperse dye.

Preferably, the aqueous ink comprises a disperse dye selected from the compounds of formulae (1 ) to (1 1 )

Such additives are usually used in amounts of from 0.01 to 20 % by weight, based on the total weight of the ink.

The inks can be prepared in customary manner by mixing the individual constituents in the desired amount of water. The inks are prepared, for example, by stirring the dyestuff components with a dispersant and milling the resulting mixture in a wet mill to a defined degree of milling corresponding to an average particle size of from 0.1 to 1.0 μΐτη.

Subsequently, the concentrated millbase - with or without the use of, for example, appropriate thickeners, dispersants, copolymers, surfactants, humectants, redispersants, sequestrants and/or preservatives, and also water - is adjusted to the desired concentration. To remove any coarse fractions present it is possible with advantage to carry out filtration of the ready-to-use ink through a microsieve of about 1 μΐη.

The method according to the invention provides dyeings with outstanding properties, in particular with better colour strength and brilliance, compared to corresponding dyeings obtained by the conventional screen printing method.
