preparation example Construction

[0065] Ink paste (containing 25% dye) preparation: 125 grams of dye is mixed with X weight equivalent (1 weight equivalent is equivalent to 125 grams) of dispersant / dispersant mixture and 375-125X grams of deionized water, and the mixture is stirred Grind in a ball mill to make the average particle size <250nm and the maximum particle size less than 1μm. It is also possible to add other additives such as bactericides, defoamers, etc., and some organic solvents during the grinding process of the ink paste.

[0066] The ink paste thus prepared (containing 25% dye) was added to the other components of the ink (organic solvent, other additives, water), and the components were thoroughly mixed in a dissolver by stirring. The inks were ready to use once they were filtered through standard commercial filter paper (Macherey-Nagel MN-614).

Embodiment 1

[0068] Fabric fibers made of polyester are padded with a solution consisting of 50 g / l of 8% sodium alginate solution, 100 g / l of 8-12% bean gum ether solution and 5 g / l of monosodium phosphate in water, and then dry. 70% of the solution was absorbed. This pretreated fabric was then printed with a drop-on-demand (piezoelectric) inkjet print head using an aqueous ink prepared as described above and comprising the following ingredients,

[0069] 3.5% dye (1)

[0070]

[0071] 2.5% Dispersant Disperbyk 190

[0072] 30% 1,5-pentanediol

[0073] 5% Diethylene glycol monomethyl ether

[0074] 0.01% fungicide Mergal K9N

[0075] 58.99% water

[0076]Let the print dry completely. Fixation was carried out by superheated steam for 7 minutes at 175°C. The print is then subjected to an alkaline reduction post-treatment, washed with warm water and then dried.

Embodiment 2

[0078] Fabric fibers made of polyester are padded with a solution consisting of 50 g / l of 8% sodium alginate solution, 100 g / l of 8-12% bean gum ether solution and 5 g / l of monosodium phosphate in water, and then dry. 70% of the solution was absorbed. The thus pretreated fabric was then printed with a drop-on-demand (bubble) inkjet print head using an aqueous ink prepared as described above and comprising the following ingredients,

[0079] 2% dye (2)

[0080]

[0081] 1% Dispersant Tego Dispers 740W

[0082] 20% glycerin

[0083] 0.01% fungicide Mergal K9N

[0084] 76.99% water

[0085] Let the print dry completely. Fixation was carried out by superheated steam for 7 minutes at 175°C. The print is then subjected to an alkaline reduction post-treatment, washed with warm water and then dried. A high-brightness orange-yellow print with excellent durability and fastness to heat and light is obtained.

Abstract

Disclosed are aqueous printing inks that are used for inkjet textile printing and contain one or several compounds of general formula (I), wherein A, B, R<1> to R<6>, and D have the meaning indicated in claim 1, methods for the production thereof, and the use thereof for inkjet textile printing.

Description

technical field [0001] Digital printing technology in the field of textiles and non-wovens will become more and more important in the future. [0002] The market demand in traditional textile printing is more flexibility in design, color and delivery time. One response to this development is digital inkjet technology. It can be directly printed from the computer to the fabric through the printing nozzle without preparing the printing screen. This new technology can improve the flexibility, efficiency and environmental adaptability of the printing technology. It can basically integrate operations, shorten printing time, and meet the requirements of rapid response to market developments and reduction of intermediate steps required in manufacturing operations. Background technique [0003] Inkjet methods typically use water-based inks, which are formed into small droplets that are sprayed directly onto the substrate. The difference between continuous outflow and intermittent...
