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 brown digital printing ink. Brown pigment extracted from euryale ferox shells is used as plant dye to replace synthetic dye commonly used in the digital printing ink in the prior art, so that the environmental pollution problems and health problems, caused by the synthetic dye, can be greatly reduced; nano-titanium dioxide is adopted to replace a bactericide used in the prior art, and is more environmentally friendly; grapheme is added in the process of ink preparation, so that fabric with ideal color fastness can be obtained without adding urea as a color fixing agent, the production cost is reduced, and the dyeing effect is improved.

Description

technical field [0001] The invention relates to the technical field of digital printing, in particular to an environment-friendly brown 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 print...
