Problems solved by technology

However, the actual test results show that small molecule solvents cannot effectively improve the dispersion effect in water-based white colorants
For example, in WO2012040889, small molecule solvents such as diethylene glycol monobutyl ether (DEGMBE) and triethylene glycol monoethyl ether (TEGMBE) were selected; however, the actual test results showed that they could not effectively improve the titanium dioxide in the white color paste. Dispersibility of powder

Abstract

An ultra-high whiteness water-based white colorant for digital textile printing ink, comprising: 40wt% to 70wt% titanium dioxide powder; 1wt% to 5wt% wetting agent; 2wt% to 12wt% dispersant; and the balance of water. The titanium dioxide powder is rutile titanium dioxide, the wetting agent is a fatty acid derivative, and the dispersing agent is a polyacrylic acid copolymer. In addition, the present invention also provides an ink composition using the ultra-high whiteness water-based white colorant.

Description

technical field [0001] The invention relates to a water-based white colorant for digital textile printing ink and an ink composition using the same, in particular to an ultra-high whiteness water-based white colorant for digital textile printing ink and an ink composition using the same . Background technique [0002] At present, although there are white colorants for preparing digital textile printing inks on the market, most of the water-based white colorants on the market have the shortcomings of insufficient whiteness and unsuitable particle size. For example, commercially available white colorants, such as DIC, Dainichiseika Color, Diamond, etc., all have poor whiteness and contain too large particles that are not suitable for use. [0003] In the currently known white colorants, small-molecule solvents are added and used as wetting agents. However, the actual test results show that small-molecule solvents cannot effectively improve the dispersion effect in water-base...
