Embodiment 1

[0022] Take red K-type reactive dye 3.0% (3.0 g), surfactants are MA-AA0.02%, NP-7.50.2% and polysiloxane derivatives (n=10) 1%, sodium dithionite is 0.3 %, the moisturizing agent is polyethylene glycol 2005%, glycerin 8%, ethylene glycol 2%, NaHCO 3 2%, the antibacterial agent is Proxelx 120.1%, sodium alginate is 5%, and the rest is deionized water, mix well, adjust the pH to 7.5 with Tris-HCl, and obtain 100 grams of inkjet ink. The physical and chemical indexes of the inkjet ink at 25° C. are: the surface tension is 35 mN / m, and the viscosity is 11.5 cP. The ink-jet ink prepared in this embodiment has good storage stability through high and low weather resistance tests. This ink prints directly on unsized fabrics with good printing fluency. After post-treatment, the color of the pattern is bright and saturated, the edges of the lines are sharpened, and the fastness to washing and rubbing are both grade 4.

Embodiment 2

[0024] Take red K-type reactive dye 10.0% (10.0 g), surfactants are MA-AA0.09%, NP-7.50.1% and polysiloxane derivatives (n=4) 1%, sodium dithionite is 0.5 %, the moisturizing agent is polyethylene glycol 20010%, glycerin 8%, ethylene glycol 2%, NaHCO 3 5%, the antibacterial agent is Proxelx 120.3%, sodium alginate is 1%, and the rest is deionized water, mix well, adjust the pH to 7.0 with Tris-HCl, and get inkjet ink. The ink-jet ink prepared in this embodiment has good storage stability through high and low weather resistance tests. This ink prints directly on unsized fabrics with good printing fluency. After post-treatment, the color of the pattern is bright and saturated, the edges of the lines are sharpened, and the fastness to washing and rubbing are both grade 4.

Embodiment 3

[0026] Take 20.0% (20 grams) of red K-type reactive dye, surfactants are MA-AA0.09%, NP-7.50.1% and polysiloxane derivatives (n=12) 0.5%, sodium dithionite is 1.0 %, the moisturizing agent is polyethylene glycol 20010%, glycerin 8%, ethylene glycol 2%, NaHCO 3 10%, the antibacterial agent is Proxelx120.3%, sodium alginate is 3%, and the rest is deionized water, mix well, adjust the pH to 7.5 with Tris-HCl, and get inkjet ink. The ink-jet ink prepared in this embodiment has good storage stability through high and low weather resistance tests. This ink prints directly on unsized fabrics with good printing fluency. After post-treatment, the color of the pattern is bright and saturated, the edges of the lines are sharpened, and the fastness to washing and rubbing are both grade 4.

Abstract

The invention discloses ink-jet ink and application thereof.The ink-jet ink is prepared from, by mass, 3.0%-25.0% of organic dye, 1.0%-2.0% of a surfactant, 0.1%-1.0% of a color fixing agent, 10.0%-20.0% of humectant, 1.0%-10.0% of alkali, 0.1%-0.5% of an antibacterial agent and the balance deionized water, wherein the pH is 7.0-8.0.The ink-jet ink is applied to cellulosic fiber inkjet printing, and a fabric can be directly printed without being starched; the printing fluency is good, the color fastness rate is high, the ink storage stability is good, and wastewater is easy to treat.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to an inkjet ink and its application. Background technique [0002] Compared with traditional printing technology, digital inkjet printing technology does not require plate making, is easy to operate, has the advantages of high printing precision, no dye waste, and no pollution. As far as the current application of inkjet printing technology is concerned, there are mainly problems such as low ink stability, slow printing speed and high ink cost. Due to these shortcomings of inkjet printing technology, it hinders its large-scale application in printing and dyeing enterprises. Chinese patent 02105814.8 uses polyols as organic solvents, and the invented ink composition has the advantages of excellent coloring strength, storage stability and not easy to block the nozzle. The invention effectively solves the problem that the fabric needs to be pretreated before printing, an...
