Paper

Paper dyeing process, the object is to dye the role of paper fibers. Mechanism of different dyes with different pulp, wood is known as basic dyes great affinity, suitable for dyeing pulp lignin content; pulp surface with a strong negative charge, then the direct dyes hardly adsorbed ions , with it to reduce the surface charge, the dye near the fiber surface is fixed. Such non-electrostatic adsorption caused, bauxite is commonly used in papermaking dye retention agent, because the majority of paper dyes are anionic, cationic aluminum compound and anionic dye-forming cation may be precipitated and adsorbed on the fiber surface which is to retain this mechanism occurs at pH 4.0-5.2, then the charge density of the aluminum ions is high, the charge is stronger.
Dyes commonly used in the paper coating colored paper, the dye and the paper fibers by covalent bond, ionic bond between, with the key, and molecular hydrogen binding forces, which depends on the color fastness of adhesion strength, exactly in what based combination, depending on the structure of the dye molecule.
