Sodium alginate,also called asAlgin, is a kind of light yellow or brown granular or powder, almost odorless and tasteless. It is a macromolecular compound with high viscosity, and a typical hydrophilic colloids. Because of its properties of stability, thickening and emulsifying, hydratability and gelling property, it is widely used in food, pharmaceutical, printing and dyeing, etc.
In printing and dyeing industry,sodium alginateis used as active dyestuff, which is superior than grain starch and other pasts. Using sodium alginate as the printing paste 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, particularly applicable to the preparation of dyeing printing paste. 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.
