Sodium alginate, also known as seaweed gel, or algin, is a kind of white or light yellow granular or powder, almost odourless tasteless. It is a kind of high viscosity polymer compound and a typical hydrophilic sol. Its stability, thickening and emulsification, hydration and gelation are widely used in food, medicine,printing and dyeing and other industries.

In printing and dyeing industry, sodium alginate is used for reactive dye printing ink, and it is superior to the food, starch and other pulp. Bright printed textile decorative pattern, line is clear, to the high amount of color, color uniformity, good permeability and plasticity.  It has been widely applied in cotton, wool, silk, nylon, etc. Various kinds of fabric printing, especially suitable for mixed dye printing paste. It also can be used as warp sizing agent, it can avoid fibers napping, friction resistance, and provide less breakage. It is effective to improve the efficiency of weaving, the cotton fiber and synthetic fibers.

Method of operation :

Active printing method: add proper amount of water to the mixer and start the high speed stirring. Resist salt S (or its substitute, in the water hardness large area can consider to add the right amount of sodium hexametaphosphate), stirring for 30 minutes. Continue to add water, and, in turn, add baking soda, such as urea fertilizer, stirring until it dissolves adequately, the whole process takes about 2 to 3 hours (associated with stirring speed and stirring method).Then into the material storage tank and let stand for 4 hours, you can join the dye used.

Disperse printing usage: adding the right amount of water in a blender, open high-speed stirring. Slowly stir in sodium alginate to dissolve sufficiently, the whole process takes about 2 to 3 hours (associated with stirring speed and stirring method).Then into the material storage tank and let stand for 4 hours, you can join the dye used.
