Company Description

In printing and textile industry 　　It 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. It 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 fibre, 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 pseudo plastic fluid, which means that it will turn watery when being cutted and restored the original viscidity after losing being cutted. 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.
