Problems solved by technology

[0005] On the other hand, digital printing accurately prints ink onto the surface of the fabric in a non-contact manner, so the color fastness is relatively low. Therefore, in the prior art, before digital printing of the fabric, it is necessary to pre-sizing the fabric. Treatment to help improve the fixation rate and color fastness of vegetable dyes
But this will increase the process of digital printing, printing and dyeing
[0006] Chinese invention patent CN103966861A provides an environmentally friendly digital printing ink and its preparation method. The ink can dye silk and cotton with good dyeing effect, but this invention only provides a single color ink preparation method, and in Organic fungicides are added to the ink, which is still not environmentally friendly

Abstract

The invention discloses an environment-friendly blue ink for digital printing. Blue pigment extracted from mulberries is adopted as vegetable dye and replaces synthetic dye commonly used in ink for digital printing in the prior art, so that the environmental pollution issue and the health issue caused by synthetic dye are greatly relieved. Nano-titanium dioxide is adopted as fungicide, so that higher environmental friendliness is achieved. Besides, graphene is added in the ink preparing process, and fabric with ideal color fastness can be obtained without adding urea as a color fixing agent, so that the production cost is reduced, and the dyeing effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of digital printing, in particular to an environment-friendly blue digital printing ink and a preparation method thereof. Background technique [0002] Digital inkjet printing technology is a great expansion of inkjet printing in the field of industrial applications. When modern computer inkjet printing technology is used for textile printing, various input means such as scanners, digital cameras, digital cameras, etc. can be used to digitally input the required patterns into the computer, and then processed by various graphics software printing color separation systems. Finally, through a computer-controlled digital inkjet printing machine, the printing ink is directly sprayed onto various fiber fabrics to print various patterns required. This printing technology is called digital inkjet printing. [0003] In recent years, digital printing technology has developed rapidly. Compared with traditional printi...
