Product Description
Products Description
In printing and textile industry sodium alginate has been a long history since sodium alginate was used in starching , packing and printing. In printing, it is the good material with wide use in the cotton, wool, silk and synthetic fibre. Especially since the reactive dye was found in the world, there has been many years' history of application. There is no other gelatinigation which can compare beauty with it by so far. Sodium alginate can't react with the reactive dye or form covalent bond as result of having second hydroxyl in its structure without the origin hydroxyl, and meanwhile having strong cathodic carboxyl in its organization. This is its great property. Therefore, it not only does not absorb the dyestuff but also excludes it. It is easy to move the dyestuff from the gelatinigation to the firbre which benefits keeping clearness and uniformity of the printing. Therefore the printing is clear, vivid, high in the dyeing quantity and has good handle and firm degree at the same time. The products of medium and low viscosity are suitable for the printing requirements of net, roll style and handwork printing. It has the flowing property of the pseudoplastic fluid, which means that it will turn watery when being cut and restore the original viscidity after losing being cut. This fits for fine printing, full ground printing and wet printing. It can make products with the features of thin line, clear profile and good uniformity.Function
1. Stabilizer
Replacing starch and carrageenan, sodium alginate can be used in beverage, dairy products, iced products.
2. Thickener and emulsion
As food additive, sodium alginate mainly used in sala flavoring, pudding jam, tomato ketchup and the canned products.
3. Hydration
Sodium alginate can make noodle, vermicelli and rice noodle more cohesiveness.
4. Gelling property
With this character, sodium alginate can be make into kinds of gel product. It also can be used as a cover for fruit, meat andseaweed products away from air and keep them stored longer.
Application
As a thickener for beverages and dairy products, sodium alginate has unique advantages in thickening: the good fluidity of sodium alginate makes the added beverage taste soft and smooth; and it can prevent the viscosity drop during product disinfection.
