Problems solved by technology

However, dyes that exist on the fabric in a molecular state are easily decomposed by light, and it is easy to lose the color effect.
[0004] The research on textile inkjet printing dye ink is very mature, but the research on pigment ink is still in its infancy, and the product is not mature enough.
At present, there are relatively few pigment inks sold and used in the market, and most of the high-quality inks are imported products, which are very expensive. Compared with domestic inks, although the price is relatively cheap, their performances are still quite different. , these current conditions limit the application and promotion of pigment-based inkjet printing technology

Abstract

The invention discloses digital printing pigment ink, which is composed of the following components in percentage by weight: 8-12% of nanoscale organic pigment, 0.5-3% of dispersing wetting agent, 0.5-2% of adhesive, 5-15% of humectant, 0.1-1% of preservative, 5-10% of viscosity regulator, 0.1-1% of pH regulator and the balance of deionized water, wherein the particle size of the nanoscale organicpigment is 50-100 nm. According to the invention, the digital printing pigment ink has the advantages of low preparation cost, good long-term storage stability, difficult flocculation, aggregation, precipitation and layering, moderate viscosity and surface tension, good fluidity of the ink in a pipeline, smooth printing, good printing effect, good washing resistance, good dry and wet rubbing fastness of a printed product, and good printing quality, and can meet the clothing wearing requirements of consumers.

Description

technical field [0001] The invention relates to the technical field of digital printing, in particular to a digital printing pigment ink and a preparation method thereof. Background technique [0002] Digital printing is to input the pattern into the computer in digital form, edit and process it through the computer printing color separation and drafting system (CAD), and then use the computer to control the micro piezoelectric inkjet nozzle to spray the special dye solution directly onto the textile or other media. , to form various high-precision patterns required. Compared with the traditional printing and dyeing process, digital printing has the following advantages: 1. The production process of digital printing greatly shortens the original process route, the speed of receiving orders is fast, and the cost of proofing is greatly reduced; 2. The principle of digital printing technology It makes its products break the limitation of traditional production of color registr...
