Sodium alginate has already been used in warp sizing, trimming paste and printing paste for a long time in history while mainly in the printing paste. It has specific function when used as active paste and color paste. Fibre has chemical reactions with active dyestuff to fix it onto the fibre. In dyeing process, the printing paste used should not disturb or join in the chemical reactive linkage otherwise it will be fixed onto the fibre, which makes the dyed fibre feel stiff and fragile and the color is not good.
In printing and dyeing industry, sodium alginate is used as additive for active dyestuff, which is superior to grain starch and other paste. Using sodium alginate as the printing paste would not affect the reactive dyes and dyeing process, at the same time it can get a brilliant and bright colors and good sharpness, with high color yield and uniformity, and it is easy washing after printing. The most important, after using sodium alginate, the fabrics feel good and look good. It is not only suitable for cotton printing, but also for wool, silk, synthetic printing, particularly applicable to the preparation of dyeing printing paste.
Middle and low-viscosity sodium alginates are all fit for the paste requirements from sieve-style printing to barrel-type printing. Actually, printing made from low-viscosity sodium alginates is more stable, which makes high-content printing paste possible.
