Embodiment 1

[0041] A kind of functional ink, by weight percentage, it is made of following composition: glycerol: 25%, carboxymethyl cellulose: 5%, S-465: 0.5%, triethanolamine: 1.2%, ammonium sulfate: 4.5%, sodium tripolyphosphate: 0.7%, potassium sorbate: 0.5%, penetrant JFC: 6%, deionized water: the rest; mix and stir each component according to the weight percentage to obtain the functional ink.

[0042] The functional ink prepared in this embodiment is matched with the acid dye inkjet ink (for example, the inkjet printing acid dye ink in ZL2010102562359 can be utilized) to be used to print the mirror image grayscale image of the desired pattern on the nylon carpet, The specific printing process includes: using the functional ink prepared in this example to print on the nylon carpet first, and then use the acid dye inkjet ink to print, and then dry, steam (25 minutes at 100° C.), Wash and then dry. At the same time, the same comparison was made with the printed matter using only aci...

Embodiment 2

[0044] A functional ink, which is made of the following components by weight percentage: 1,2-propanediol: 25%, polyvinylpyrrolidone K-40 (PVP-K40): 1%, S-465: 1%, Ammonium sulfate: 0.5%, sodium tripolyphosphate: 2.2%, dodecyldimethylbenzylamine chloride: 7.5%, isothiazolinone: 0.03%, deionized water: the rest; The functional ink is obtained by mixing and stirring the said weight percentage evenly.

[0045] The functional ink prepared in this embodiment is matched with the water-based pigment inkjet ink (for example, the water-based pigment digital printing ink in ZL2006100265953) for printing on cotton fabrics, and its specific printing process includes: using this embodiment The functional ink prepared in above was pre-printed on cotton fabric, then printed with water-based pigment inkjet ink, and dried and baked (at 160°C for 3 minutes) to obtain the finished product. At the same time, the same comparison was made with the printed matter using only water-based pigment inkje...

Embodiment 3

[0050] A functional ink, which is made of the following components by weight percentage: diethylene glycol: 21%, polyethylene glycol 400: 5%, PVP-K40: 4.5%, S-465: 0.5 %, sodium dodecylsulfonate: 0.45%, triethanolamine: 1%, sodium carbonate: 1.5%, EDTA-disodium: 0.5%, penetrant JFC: 0.5%, deionized water: the balance; According to the weight percentage, mix and stir evenly to obtain the functional ink of this embodiment.

[0051] The functional ink prepared in this embodiment is matched with the reactive dye inkjet ink (for example, the reactive dye ink in ZL2011100060210) for printing on the rayon filament fabric, and its specific printing process includes: using this embodiment The functional ink prepared in the example was pre-printed and dried on cotton fabric, then printed with reactive dye ink, dried, steamed (15 minutes at 100°C), washed in cold water, washed in hot water, soaped Wash, wash and dry to get the finished product. Simultaneously, compare with the digital ...

Abstract

The invention discloses functional ink. The functional ink is prepared from, by weight, 5-40% of a wetting agent for printing inks, 0.1-5% of a viscosity modifier, 0.1-10% of a surface active agent, 0.1-5% of a pH regulator, 0.1-5% of a complexing agent, 0.1-2% of bactericide, 0.1-30% of functional auxiliaries and the balance water. The functional auxiliaries are one or more of a rapid color developing agent, a fastness promoting agent, a penetrant, a softening agent, an antistatic agent, an anti-stiff finishing agent, an antibacterial finishing agent and a waterproof finishing agent. In addition, the invention discloses a printing method of the functional ink. The method comprises the steps that 1, before ink jet ink is used for jetting ink, the functional ink is used for performing pre-printing on a printing medium; 2, after the jet ink is used for performing ink printing on a printing medium, the functional ink is used for performing post-printing on the printing medium; 3, the functional ink and the jet ink are used for simultaneously performing at least one printing on the printing medium.

Description

technical field [0001] The present invention relates to a functional ink for inkjet printing, in particular to a functional ink that can cooperate with various inkjet inks to achieve excellent printing effects on various printing media. In addition, the present invention also relates to A printing method of the functional ink belongs to the technical field of inkjet printing. Background technique [0002] At present, inkjet printing technology has been widely used in many fields such as building decoration materials printing, textile printing, packaging and decoration materials printing, etc. It uses an inkjet printer to print different types of inkjet inks onto corresponding printing media to form desired printing patterns. Due to the diversity of printing media, especially for some printing media that do not have an ink-absorbing coating or are not suitable for a certain type of inkjet ink, especially in the field of textiles, before inkjet printing, it is usually necessa...
