As a reactive dye printing agent, sodium alginate has a special property. During reaction of fibre and reactive dye, the dye is fixed in fibre and printing agent do not attend this reaction, otherwise, the agent will e fixed in the fibre and make it hard fragile and bad color. if you use sodium alginate as a printing agent is also suitable for cotton, wool, silk and synthetic fibre. You can contact us if you want to order this product.

In Printing and Textile Industry It has been a long history since sodium alginate has been used in warp sizing, packing and printing. In printing, it is an ideal kind of material with wide applications in the cotton, wool, silk and synthetic fiber. Especially since active dyestuff came into the world, there has been many years' history of application. Till now, there is no other paste which can compare beauty with it. The biggest characteristic of it is that it won't react with active dyestuff and form covalent bond owing to own second hydroxyl in its structure without the origin hydroxyl, and meanwhile own strong cathodic carboxyl on its basal ring. Therefore, it not only doesn't absorb the dyestuff but also excludes it. It is easy to move the dyestuff from the paste to the fiber, which benefits keeping clearness and uniformity of the printing. Accordingly, the printing is clear, vivid, high in the dyeing quantity and has good hand touch and firm degree at the same time. Sodium alginates of medium and low viscosity are both suitable for the printing requirements of net, roll style and handwork printing. Owning theological property of tpseudo-plasticity, which means that it will turn watery when being cut and restore the original viscidity after losing cutting, they apply to printing fine flower pattern, full ground printing and wet printing, which is characterized by refined line, clear profile and good uniformity.
