Liquid Direct Dyes for Paper dyeing red, blue, yellow
Paper dyes
Paper dyeing process, the object of the dye's role is paper fiber. Dye and different mechanisms of action of different pulp, such as alkaline dyes have a great affinity for lignin, suitable for high content of pulp with pulp; Pulp with a strong negative surface, the direct dye is almost no adsorption of negative ions , With the real surface charge decreases, the dye near the fiber surface was fixed. This adsorption is caused by non-electrostatic forces, aluminum vanadium is commonly used in papermaking dye retention agent, because most papermaking dye is anionic, cationic aluminum compounds and anionic dye cationic precipitation and adsorption in the fiber surface was retained , This mechanism occurs in the pH value of 4.0-5.2, when the charge density of aluminum ions, charge strong role.
