Application of white glue in printing

White glue can be used on knitted fabrics, especially when animals or cartoon characters are partially printed on the fabric to obtain realistic patterns. The color overprint printing of white glue can be applied to high-grade dark fabrics, such as denim. Printed with various colored stripes, it has excellent visual effect. Put the self-made adhesive, protective colloid, titanium dioxide, plasticizer, emulsifier dispersant, etc. into the mixer, use a high-speed disperser,

White glue can not only be used for white overprint printing alone, but also can be used for color overprint printing in combination with various paint colors. Overprint printing on dark-colored fabrics with white glue is a special pigment printing.

1. Preparation of white glue

Put the self-made adhesive, protective colloid, titanium dioxide, plasticizer, emulsifier dispersant, etc. into the mixer, and use a high-speed disperser to uniformly mix the raw materials; adjust the pH value to 7-8 with ammonia water, and add a thickener to adjust. to a suitable consistency, then add an appropriate amount of antifungal agent and stir evenly; filter the evenly mixed material to obtain a finished white mucilage.

2. The effect of softener on white mortar

The purpose of adding a softener to the white mortar is to improve the feel of the white mortar after printing, to make the printing pattern soft and non-sticky, and the softness of the mixed emulsion with stearic acid, paraffin, and peregal as the main components. When the dosage of white glue is less than 2.5%, the softening and anti-sticking effect is poor. When the dosage is higher than 4%, the softening effect is good, but the anti-sticking effect is not ideal. When the dosage of softening agent is 2.5%-4% , to get the best printing effect.

3. Application

White glue overprint printing makes the pattern block surface on the fabric have a certain thickness, which can reflect a better three-dimensional sense and block surface gloss effect.
