Problems solved by technology

[0007] Finally, although it is known to use N-methylmorpholine-N-oxide (NMMO) as a co-solvent at present, to improve the dye-carrying capacity of the inkjet ink itself, for example US 6451098 B1 and US 6596066 B2 (all of which are referenced in full here) ), but this material does not address separately improved properties in fabric pretreatment

Embodiment 1

[0064] In a first example, the coating formulations in Table 1 below were applied to cotton fabrics as described below and dried at 100°C. Then print the fabric according to the description, and according to the following L * a * b * Steam and / or wash as indicated in the measurement description.

[0065] Element

[0066]For Example 1, ingredients 1, 2 and 3 were mixed with 1 / 2 the water to form the first solution. Ingredient 4 and remaining water were then mixed with ingredients 6, 7, 8 and 9 to form a second solution. The second solution was first applied by padding and dried in a convection air oven at 100°C, and the first solution was applied over the coating by padding, also dried at 100°C. The percentage of total solids is about 12%. The percent dry adhesion to the above formulation was about 9-10%. This represents a wet attachment percentage of about 90-99%. The padding speed is 15-60 ft / min, ideally 20-30 ft / min is achieved with 20-60 psig pressure rol...

Embodiment 2

[0068] In the second example, the coating formulations in Table 2 below were added to cotton fabrics under the same preparation conditions and dried at 100°C.

Abstract

A method of producing a printed substrate so as to improve the adhesion, colorfastness and washfastness of ink jet inks including reactive and acid dye-based ink jet inks printed onto the substrate, the method includes the steps of providing a substrate, treating the substrate with an aqueous coating formulation comprising NMMO, a cationic polymer or copolymer, and a fabric softener, treating the substrate with an imbibing aqueous solution of either urea, and a component selected from sodium bicarbonate, sodium carbonate or combinations thereof, or ammonium salts of multifunctional weak acids, drying the substrate, printing on the substrate with an ink jet ink containing acid or reactive dye-based inks depending on the coating, and optionally post treating the printed substrate with a curing step.

Description

field of invention [0001] The present invention relates to substrates for digital printing, in particular to methods of processing substrates for inkjet printing, and to substrates prepared by such methods. In particular, the present invention relates to imbibition solutions, alone or in combination with coating formulations, for treating fabric substrates for inkjet printing, methods of treating such fabrics, and articles made by such methods. This method facilitates the use of such fabrics in commonly used inkjet or laser printing devices, such as wide or narrow format inkjet and laser printers. Background technique [0002] The inkjet printing method is a rapidly growing, commercially important printing method because of its ability to produce economical, high quality, multi-tone prints. In fact, the inkjet printing method is becoming the printing method of choice for producing color hardcopies of narrow and wide computer-generated images consisting of diagrams and text....
