Technical Field

The invention relates to the technical field of printing and dyeing mucilage, in particular to a digital printing dot imitating white mucilage.

Background

At present, along with social development, people have higher and higher requirements on clothes, and the appearance of the clothes can be effectively improved by printing and dyeing patterns on the clothes, so that the clothes are more in line with the aesthetic perception of people and attract consumers.

In the printing and dyeing of clothes, mucilage is generally used as a printing and dyeing material, and patterns are formed by printing the mucilage on cloth.

The existing mucilage mostly adopts acrylic emulsion, and patterns attached to cloth are formed after the acrylic emulsion is solidified so as to realize printing and dyeing.

The above prior art solutions have the following drawbacks:

however, the common acrylic emulsion is maintained in an emulsion state by an emulsifier, but because the acrylic acid and water are incompatible, if the acrylic acid and water are not stirred continuously, the acrylic resin in the acrylic emulsion is easy to precipitate, so that a system of the acrylic emulsion is damaged, and because of the instability of the acrylic emulsion system, the acrylic resin in the printed and dyed pattern is unevenly distributed, so that the adhesion force is unevenly distributed, and further, the printed and dyed pattern is easy to fall off locally, so that the appearance of the garment is influenced, and therefore, the space for improving the acrylic emulsion is provided.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide the imitation digital printing dot white cement which has the effect that an acrylic resin system is stable, so that a pattern is not easy to fall off locally.

The invention also aims to provide a preparation method of the digital printing imitation dot white glue paste, which has the effect that an acrylic resin system is stable, so that the pattern is not easy to fall off locally.

One of the above objects of the present invention is achieved by the following technical solutions:

the digital printing imitation dot white adhesive cement comprises the following components in parts by mass:

40-60 parts of water-based acrylic emulsion;

10-20 parts of a whitening agent;

0.5-1 part of thickening agent;

0.2-0.5 part of attapulgite;

and 2-3 parts of an auxiliary agent.

By adopting the technical scheme, the rheological property of the aqueous acrylic emulsion is effectively changed by adding the attapulgite into the aqueous acrylic emulsion, so that the adhesive cement has excellent pumping and screening performances, the adhesive cement is not easy to break, the continuous quality is better during printing and dyeing, an adhesive cement system is stable and not easy to precipitate, a suspension liquid is not easy to stratify, the adhesive discharge is uniform during printing and dyeing, and acrylic resin in printed and dyed patterns is uniformly distributed, so that the printed and dyed patterns are firmly adhered to cloth everywhere, the local part is not easy to peel off, and the service life of clothes printed and dyed with the patterns is effectively prolonged;

the whitening agent is added into the mucilage to cover basic variegated colors brought by all the raw materials, so that the white mucilage is white, and if the pigment is added for color matching, the white mucilage is not easily affected by the variegated colors, and the color is uniform and beautiful;

by adding the auxiliary agent, the dispersibility is effectively improved, and the pH value is adjusted, so that the quality of the white cement is better.

The present invention in a preferred example may be further configured to: the paint also comprises the following components in parts by mass:
