Knowledge of Printing Thickener

It is not difficult to find that many clothes have printed figures. Its presence adds a lot of color to the fashion industry, and also meets people's requirements for diversification and personalization, so we can see that the application of printing process is actually more More widely. It is often necessary to use two main materials, glue and color paste, when printing, and a certain consistency is required for adjustment, but often in order to control costs, the input of raw materials and the consistency of the printing paste are always difficult to control, which is also The reason for printing thickener.

1. What is the printing thickener?

Printing thickener is a liquid water-based thickening agent composed of a polyurethane component. It is a liquid with excellent fluidity, which is easy to prepare and use. It is widely used in cotton fabrics, chemical fiber fabrics, paint printing pastes, printing processes, printing and dyeing and other product systems, and can be used in most water-based systems, such as emulsion systems, dispersion systems, latex paints, etc. , Polyvinyl acetate and various copolymers) have good compatibility.

Second, the harm of too thin color paste?

1. When the printing paste is made, the consistency is reduced, which will affect the stability of the color paste, resulting in a poor printing effect.

2. It is easy for the printing particles to sink and the printing to fade.

3. Product features of printing thickener?

1. Excellent dry and wet rubbing fastness, good feel.

2. It has clear and excellent printing and dyeing effect, safe and convenient to use.

3. Its performance is comparable to imported products, and the price has obvious advantages.

4. It has good compatibility with printing adhesives, printing coatings and other additives, it can thicken the state slurry, and the prepared water slurry can also be mixed with various water-in-oil type state slurry. Transfer the glue or color paste on the printing screen and printing roller to the fabric, so that the dye and fiber can be well combined.

5. Ensure that the printed patterns are clearly defined. After the dye is fixed, the reaction products and residues will be easily removed in the downstream process, and will not have any adverse effects on the vividness, scrubbing fastness and feel of the printed fabric.

Fourth, the use of printing thickener

1. When preparing water slurry, first weigh a certain amount of water and stir at high speed, add an appropriate amount of printing thickener to achieve the required consistency.

2. When the density of the emulsified slurry is not enough, add a small amount of printing thickener while stirring.

3. The amount of addition depends on the material system. Please test the appropriate amount before use.
