Product Description Sodium Alginate(CAS #:9005-38-3)are natural water-soluble polymers produced from brown seaweed. A major application for sodium alginate is in reactive dye printing, as thickener for reactive dyestuffs (such as the Procion cotton-reactive dyes) in textile screen-printing and carpet jet-printing. Alginates do not react with these dyes and wash out easily, unlike starch-based thickeners. It had been the most popular printing thickener in roller printing.

Directions In printing and dyeing industry, sodium alginate is used as printing thickener and would not affect the reactive dyes and dyeing process.At the same time it can get a brilliant and bright colors and good sharpness, with high color yield and uniformity. It is not only suitable for cotton printing, but also for wool, silk, synthetic printing. In addition, it can also be used as warp sizing, not only saving a large amount of grain, but also making the warp fibers without raising, and with friction resistance, low breakage rate, thereby enhancing the efficiency of weaving, effective for cotton fibers and synthetic fibers. (1)Medium and low degree viscosity of sodium alginate is both suitable for the requirement of screen printing and roller printing. (2)low viscosity sodium alginate are more stable for making printing paste, which make it possible to make high content printing paste. This kind of printing paste will come into being dense film during drying and raise coloring rate.
