Printing paste refers to the polymer compound, which thickens the printing color paste. Sodium alginate as a warp sizing, finishing paste, printing paste and so has a long history, but the main terms used in the printing paste. Sodium alginate paste for reactive dyes, with unique properties. Fiber and dyes for chemical reactions, the dye fixed on the fiber in the dyeing process used in the printing paste should not interfere or participate in chemical bonding. If the paste part in the reaction, it will fixed on the fiber, which causes the fibers dyed hair feel hard, crisp, good color. When using sodium alginate as printing paste, the reactive dyes and fiber without affecting the dyeing process, while the printed pattern clear, bright and high color content, feel good. Cotton not only for color printing, also applies to wool, silk, synthetic printing.
Medium viscosity and low viscosity sodium alginate is suitable for printing from the screen to the drum-type printing paste requirements. In fact the low viscosity sodium alginate with a more stable preparation of printing paste, which makes high levels of printing paste prepared as possible, this printing paste can result in the drying process produces a dense membrane, so that coloring rate increased.
