Aqueous printing inks for use in the ink-jet printing method the production and the use on textile fibre materials therof
An aqueous inkjet printing ink including one or more reactive dyes, sulfolane and a buffer system and having a pH of not more than 7.0 when one or more of said reactive dyes have reactive systems of the vinyl sulfone series is prepared and used on textile fiber materials.
[0001] Digital printing techniques will become increasingly important in the future in the textile area as well as in the nontextile area.
[0002] Changed market expectations in conventional textile printing demand more flexibility in design, color and delivery time. Digital inkjet technology is the answer. By making it possible to print directly from the computer via printing nozzles without the need to prepare printing screens, the new technology improves printing process flexibility, efficiency and environmental performance. It provides substantially integrated operations, shortens printing times and meets the demand for rapid reaction to market developments and for fewer intermediate stages in the production process.
[0003] The inkjet printing process is usually carried out using aqueous inks, which are sprayed as small droplets directly onto the substrate. There is a continuous form of the process, in which the ink is pressed piezoelectrically through a nozzle at a uniform rate and deflected onto the substrate by an electric field, depending on the pattern to be produced, and there is an uninterrupted inkjet or drop-on-demand process, in which the ink is expelled only where a colored dot is to appear. The latter form of the process employs either a piezoelectric crystal or a heated cannula (bubble or thermal jet process) to exert pressure on the ink system and so eject an ink droplet. These techniques are described in Text. Chem. Color, volume 19 (8), pages 23 ff and volume 21 pages 27 ff.
[0004] This highly sensitive microtechnology requires the development of tailored dye preparations (inks) meeting, for example, high requirements with regard to purity, particle size, viscosity, surface tension, conductivity, physico-chemical stability, thermophysical properties, the pH, the absence of foam, color strength, fastness level and stability in storage. Commercially available reactive dyes in the form of their powder, granular or liquid formulations of the kind used for conventional, analog textile printing contain significant electrolyte quantities, dustproofing agents and standarizers which lead to massive problems in inkjet printing. On the other hand, dye inks as used for nontextile materials, for example paper, wood, plastics, ceramics, etc. provide only unsatisfactory results with regard to ease of application and print color yield and fastnesses on textile material.
[0005] The European patent applications EP-A 0 886 000 and EP-A 0 885 998, EP 0 620 116, EP-A 0 606 777, DE-A 4417718, DE-A 4417719 describe dye inks containing fiber-reactive dyes. These dye inks have some application weaknesses, for example unsatisfactory dye ink stability or low dye yield owing to insufficient interaction of the dyes from the ink with the fiber. The European patent specification EP-A 0 602 885 describes sulfolane-containing dye inks for the nontextile area which are not suitable for textile application. Consequently, there is a demand for novel printing inks for the inkjet process with fiber-reactive dyes that have improved properties, especially application properties.
[0006] It is an object of the present invention to provide printing inks that do not have the abovementioned disadvantages.
[0007] It has now been found that, surprisingly, aqueous printing inks containing sulfolane, which does not impair the reactivity of reactive dyes and at the same time substantially prevents nozzle cloggage, one or more reactive dyes and a buffer system ensuring the functionality of the reactive groups provide excellent results.
[0008] The present invention accordingly provides aqueous textile inkjet printing inks including one or more reactive dyes, sulfolane and a buffer system and having a pH of not more than 7.0 when one or more of said reactive dyes have reactive systems of the vinyl sulfone series.

[0034] The printing inks of the invention may further include customary additives, for example viscosity moderators to set viscosities in the range from 1.5 to 40.0 mpa*s in a temperature range from 20 to 50° C. Preferred inks have a viscosity of 1.5 to 20 mPa*s and particularly preferred inks have a viscosity of 1.5 to 15 mPa*s.
[0035] Useful viscosity moderators include rheological additives, for example: polyvinylcaprolactam, polyvinylpyrrolidone and their copolymers polyetherpolyol, associative thickeners, polyurea, polyurethane, sodium alginates, modified galactomannans, polyetherurea, polyurethane, nonionic cellulose ethers.
[0036] As further additives the inks of the invention may include surface-active substances to set surface tensions of 20 to 65 mN/m, which are adapted if necessary as a function of the process used (thermal or piezotechnology).
[0037] Useful surface-active substances include for example:
[0038] nonionic surfactants, butyidiglycol, 1,2-hexanediol.
[0039] The inks may further include customary additives, for example substances to inhibit fungal and bacterial growth in amounts of 0.01 to 1% by weight based on the total weight of the ink.
[0040] The inks may be prepared in a conventional manner by mixing the components in water.
[0041] The dye inks of the invention are useful in inkjet printing processes for printing a wide variety of pretreated materials, such as silk, leather, wool, polyamide fibers and polyurethanes, and especially cellulosic fiber materials of any kind. Such fiber materials are for example in the natural fiber cellulose fibers, such as cotton, linen and hemp, and also pulp and regenerated cellulose. The printing inks of the invention are also useful for printing pretreated hydroxyl- or amino-containing fibers present in blend fabrics, for example blends of cotton, silk, wool with polyester fibers or polyamide fibers.
[0042] In contrast to conventional textile printing, where the printing ink already contains all the fixing chemicals and thickeners for a reactive dye, in inkjet printing the auxiliaries have to be applied to the textile substrate in a separate pretreatment step.
[0043] The pretreatment of the textile substrate, for example cellulose and regenerated cellulose fibers and also silk and wool, is effected with an aqueous alkaline liquor prior to printing. To fix reactive dyes there is a need for alkali, for example sodium carbonate, sodium bicarbonate, sodium acetate, trisodium phosphate, sodium silicate, sodium hydroxide, alkali donors such as, for example, sodium trichloroacetate, sodium formate, hydrotropic substances such as, for example, urea, reduction inhibitors, for example sodium nitrobenzenesulfonates, and also thickeners to prevent flowing of the motives when the printing ink is applied, for example sodium alginates, modified polyacrylates or highly etherified galactomannans.
[0044] These pretreatment reagents are uniformly applied to the textile substrate in a defined amount using suitable applicators, for example using a 2- or 3-roll pad, contactless spraying technologies, by means of foam application or using appropriately adapted inkjet technologies, and subsequently dried.
[0045] After printing, the textile fiber material is dried at 120 to 150° C. and subsequently fixed.
[0046] The fixing of the inkjet prints prepared with reactive dyes may be effected at room temperature or with saturated steam, with superheated steam, with hot air, with microwaves, with infrared radiation, with laser or electron beams or with other suitable energy transfer techniques.
[0047] A distinction is made between one- and two-phase fixing processes:
[0048] In one-phase fixing, the necessary fixing chemicals are already on the textile substrate.
[0049] In two-phase fixing, this pretreatment is unnecessary. Fixing only requires alkali, which, following inkjet printing, is applied prior to the fixing process, without intermediate drying. There is no need for further additives such as urea or thickener.
[0050] Fixing is followed by the print after treatment, which is the prerequisite for good fastnesses, high brilliance and an impeccable white ground.
[0051] The prints prepared with the dye inks of the invention, especially on cellulose fiber materials, have high color strength and a high fiber-dye bond stability not only in the acidic but also in the alkaline range, good lighffastness and very good weffastness properties, such as wash, water, seawater, cross-dyeing and perspiration fastnesses, and also good fastness to heat setting and plating and crockfastness.
