Disperse Printing Thickener
Printing thickener is one of the most commonly used thickeners in the printing industry. In printing, two main materials, glue and color paste, are used. And because under high shearing force, the consistency will be reduced, so thickener is used to increase the consistency of the printing material, then printing thickener is needed.
The main function of the printing thickener is to provide good rheological properties, transfer the glue or color paste on the printing screen and printing roller to the fabric, so that the dye and fiber are combined together to ensure that the printing pattern is clear. The pattern is clear, the color is bright and uniform; when the dye is fixed, the reaction products and residues are easily removed in the downstream process, making the fabric feel soft. It can be seen that printing thickeners play a very important role in the printing industry.
Disperse printing thickener is a kind of cross-linked polymer compound emulsion thickener. When it is diluted with water and neutralized, its water-based polymer particles will quickly expand. Under this condition, the printing material will become clear Very sticky. The disperse printing thickener can effectively improve the low-shear viscosity and make the dye printing system have higher pseudoplasticity. Dye printing prepared with disperse printing thickener as the main thickener has a higher yield value and gel structure. This structure will show up after the shear force disappears. Therefore, the disperse printing thickener is suitable for preparation with moderate Three-dimensional pattern effect printing.
Printing Thickener China
The thickening effect of Printing Thickener China:
1. Strong thickening effect, easy to adjust slurry, good color paste stability, stable wet and dry fastness, good hand feeling, and strong fluidity, leveling and splash resistance of the original liquid after thickening.
2. It is stable to microorganisms and enzymes, does not affect the performance of the stock solution, and improves the quality of the product; it provides good rheological properties for dyes or pigments, which is easy to operate and use, so that it is evenly distributed during printing, and has a clear and excellent printing and dyeing effect. Safe and reduce raw material costs.
3. The increase in consistency makes it easier to clean off reaction products and residues after the dyes in the printing are fixed. Its performance is comparable to imported products, and the price has obvious advantages.
4. Good fastness, improve color yield and vividness, no skinning on the surface, no blocking of the net during printing; better penetration and transfer of dyes into the textile, combined with fibers, forming a clear outline Textile printing pattern.
