Problems solved by technology

It can be seen from the above-mentioned prior art that in the preparation process of pigment-based inkjet ink, the pigment is usually prepared with a dispersant to make a color paste, and then it is compounded with other additives such as a penetrating agent and a humectant to obtain a pigment-based inkjet ink. Although the pigment ink has good stability, its hiding power is not enough

Abstract

The invention provides a preparation method of an inkjet printing microcapsule pigment ink based on multi-layer self-assembly. The preparation method comprises: preparing an activated microcapsule pigment dispersion liquid, adding to an acrylamide microemulsion, stirring and mixing, adding to ammonium persulfate, and carrying out a reaction to obtain a polymer coating layer; preparing a sodium alginate solution, adding the prepared polymer-coated microcapsule pigment, adding a calcium chloride solution, and carrying out a reaction to obtain a sodium alginate microsphere arranging layer; and adding to a Tris-HCl buffer solution containing dopamine hydrochloride, carrying out a reaction to obtain a pigment paste, carrying out mixing grinding treatment on the pigment paste, sodium dodecylbenzenesulfonate, propylene glycol, ethanol, deionized water and citric acid, and sequentially filtering to obtain the pigment ink. According to the present invention, the prepared pigment ink has characteristics of good stability, good affinity with cotton fabrics and strong hiding power, and can obtain high quality patterns in inkjet printing of cotton fabrics.

Description

[0001] Technical field: [0002] The invention relates to the technical field of digital inkjet printing, in particular to a multilayer self-assembled inkjet printing pigment ink, a preparation method thereof, and a printing molding process on cotton fabrics. [0003] Background technique: [0004] Digital inkjet printing technology is a clean high-tech printing technology without environmental pollution. Its process is to input the image processed by digital technology into the computer, edit it through the computer printing color separation system, and then control the inkjet printing by printing and dyeing special software. System, spray ink directly onto various fabrics to form the printed fabrics required by the design. Digital inkjet printing has three major technical integrations: first, the printing control software; second, the inkjet printing machine; and finally, the ink. Ink, as a consumable material required for inkjet printing production, plays a pivotal role in ...
