Sodium alginate is used in textile dyeing.
Sodium alginate slurry can be perfectly applied to rotary screen printing, so that the printed matter is colorful, colorful, full of layers, and lively patterns. Excellent printing results can be achieved, especially when printing large surface patterns. Due to the high requirements of rotary screen printing for dilution resistance, temperature resistance and non-delamination of the original pulp, controlling the rheology and permeability of the printing paste is one of the important factors determining the quality of rotary screen printing. Printing running performance, surface color, amount of dye to the surface, smoothness of the pattern contour, etc. Today we will take you to understand the application of sodium alginate slurry in rotary screen printing

1. Excellent rheology: sodium alginate slurry can ensure excellent rheology when used in rotary screen printing. Rotary screen printing requires the paste to be able to be easily scraped out of the mesh while maintaining a smooth profile and uniformity. surface, so the puree is usually required to have excellent rheology and good thixotropy. Secondly, the clarity of the pattern contour is not only related to the rheological properties of the original paste, but also often to the migration characteristics of the original paste itself.

2. Good permeability: The permeability of the original pulp is an important criterion for selecting rotary screen printing puree. Since the color paste is accumulated on the surface of the fabric through the mesh during printing, unlike cylinder printing, the color paste enters the gap of the fabric through the extrusion of the flower tube printing tube or the reciprocating scraping pressure of the flat mesh. Printing. Therefore, it is easier to achieve a uniform surface effect and richer colors by choosing a sodium alginate paste with strong permeability.

3. Water holding capacity: When rotary screen printing is used to print hydrophobic synthetic fibers, some purees with poor water holding capacity will cause serious bleeding.

4. Pulp spinnability: The puree with excellent spinnability has strong adhesion to the fabric. This property is even more important when rotary screen printing is used for synthetic fabrics. If the conjunctiva of the original sticker is not adhered well, it will often peel off, stain, and contaminate each other. Therefore, this is also one of the important reasons for choosing sodium alginate puree when rotary screen printing.
