Problems solved by technology

[0005] In recent years, a kind of imitation active pigment printing adhesive has appeared on the market. Although this kind of product has a certain improvement in hand feeling, and the dry / wet rubbing fastness can also reach level 3, but due to the inherent defects of acrylate adhesive , under the condition that the adjusted formula is soft, the adhesive is easy to lose water and solidify
During the printing process, the adhesive is easy to attach to the printing screen. When the adhesive loses water, it is easy to appear the phenomenon of sticking and blocking the screen, which seriously affects the production efficiency of the printing and dyeing factory.
[0006] On the other hand, in the existing imitation active pigment printing adhesive processing technology, its raw material mixing is not very uniform, its mixture is easy to layer, and its follow-up reaction is not very sufficient
Therefore, the adhesive directly obtained by this process has a relatively low solid content, generally between 35% and 40%, which will cause waste of raw materials on the one hand; on the other hand, its bonding effect is relatively poor
