The anionic direct dye has lower dyeing cost and better lightfastness, while the cationic direct dye is more convenient in the process of mixing color and changing color.

The application characteristics of liquid dyes in kraft liner board was discussed in this paper, and the performances of cationic and anionic direct dyes were analyzed.

The paper compares four types of dyes using in China,they are basic dyes,alkali basic dyes,modified specific dyes and anionic direct dyes base in their performance and cost.

In this paper, an aquatic solution of Diabasic Magenta (MIC) as a typical cation dyes was decolored by Flocculant(PFAS).

The relationship between the molecular structures of cation dyes and their mixing properties were studied by calculating inorganic values and organic values of dyes.

In the decolorizing testes of this paper, The series simulated wastewater contained typical cation dyes.
