Sodium alginate use：

1. In printing and dyeing industry, sodium alginate has unique properties, print out pattern bright-coloured, line is clear, the color yield high, colour and lustre is uniform, ink the drying speed is fast, easy desizing, permeability and feel is the best. Middle and low viscosity sodium alginate are suitable for dyeing and printing requirements.

2.In the textile industry, sodium alginate can improve cotton gloss and strength, weaving without fuzz, not to drop powder, cloth cover smooth, easy elution; Sodium alginate used for warp sizing, not only to cotton fiber effectively, the synthetic fiber sizing, also can obtain good results.
