Embodiment 1

[0046] A color brightening agent (deepening agent) for digital printing white ink, which is prepared from the following mass fraction components:

[0047]

[0048]

[0049] The method for preparing the above-mentioned digital printing white ink coloring brightening agent (deepening agent) includes the following steps:

[0050] (1) First add the water in the formula to the reaction kettle, then turn it on and stir at 100rpm, then add pyridine and its derivatives, benzyl compounds, fatty amines and its derivatives, and the reaction will slowly and automatically rise to 90-100 ℃, control the temperature well to prevent the product quality from being affected by too fast or too high temperature, heat preservation reaction for 3 hours;

[0051] (2) Then add polypropylene polymer compound and its derivatives to react for 2 hours when the temperature is lowered to 50°C;

[0052] (3) Add polyacrylic acid and its derivatives, emulsifier, fatty alcohol, and polysilicon oxide to react for 50 min...

Abstract

The invention provides a digital printing white ink coloring brightener. The digital printing white ink coloring brightener is prepared from, by mass percentage, 5.0%-8.0% of pyridine and derivativesthereof, 1.0%-5.0% of polyacrylic acid and derivatives thereof, 0.1%-10.0% of polypropylene polymer and derivatives thereof, 1.0%-15.0% of benzyl compounds, 2.0%-8.0% of an emulsifier, 8.0%-10.0% of fatty amines and derivatives thereof, 0.1%-10.0% of polysilicon oxides, 1.0%-5.0% of fatty alcohols, and the balance water. By adopting the digital printing white ink coloring brightener, after printing of white and light inks, patterns are prominent, layers are distinct, the coloring rate and the display rate are increased, the color difference and stain after printing are reduced, the light fastness, washing and soaping fastness, rubbing fastness, perspiration fastness, ironing fastness, sublimation fastness and the like are improved, and the pass rate of finished products is increased.

Description

Technical field [0001] The invention belongs to the technical field of textile finishing agents, and specifically relates to a digital printing white ink color brightening agent, and also relates to a preparation method of the digital printing white ink color brightening agent. Background technique [0002] At present, the common problems and difficult technical difficulties for all fibers in digital printing white and light inks are that the patterns are dull, unclear, not bright, no three-dimensional, insufficient color, low color rate, and large color difference after printing. , There are stains and streak defects, the gloss of the fabric fiber after printing and the color fastness after dyeing are not ideal, and the color strength of the printing, dry and wet rubbing fastness and light fastness are difficult to achieve the desired effect. [0003] CN 109629261A discloses a brightening agent for ink printing black base plate and a preparation method thereof. The brightening age...
