Development Prospect And Physical Properties Of X - Type Cationic Dyes

Rugao Xingwu Chemical Co.,Ltd | Updated: Jun 19, 2017

     Cationic dyes are produced with the development of petrochemicals. In the 1950s, with the advent of acrylonitrile fibers, Geigy and Bayer of Germany have developed cationic dyes for acrylonitrile fibers. China in the early 60s have also been research and development to produce the first generation of a variety of cationic dyes. 70 years and the development of the second generation of X-type cationic dyes, to expand the chromatographic range, improve the dyeing performance, taking into account the compatibility between the ternary color. 70 years of trial production and production of the third generation of M-type cationic dyes, known as the migration of cationic dyes, can be applied to a variety of acrylonitrile fiber dyeing.

The world's production of dyes in developed countries, the production of cationic dyes and alkaline dye production accounted for only 10% of the total output of dyes. China's cationic dye production in the 1990s was more than 2 thousand tons / year, accounting for more than 1% of total dyestuff production, but also part of the export. Cationic dyes in the X-type three primary colors and cationic pink FG and brilliant red 5GN for the larger varieties.X-Type Cationic Dyes

    In recent years at home and abroad to research and development of dyeing performance, special, new structure of the species, as well as the improvement of old products, energy saving, waste management and other fields. Organic pigments refer to a class of pigments made from organic compounds having a color and a range of other pigment properties. Pigment characteristics include light fastness, water immersion, acid, alkali resistance, organic solvents, heat resistance, crystal stability, dispersibility and hiding power. The difference between an organic pigment and a dye is that it has no affinity for the object to be colored and the object is colored only by adhering the organic pigment to the surface of the object or by mixing it inside the object by means of an adhesive or a film-forming substance.X-Type Cationic Dyes

The production of intermediates, production equipment and synthesis processes are similar to the production of dyes, so often organic pigments in the dye industry in the production. Organic pigments compared with the general inorganic pigments, usually have a high color strength, easy to grinding and dispersion of particles, not easy to precipitate, the color is also more bright, but light fastness, heat resistance, poor weather resistance. Organic pigments are commonly used for the coloring of materials such as inks, coatings, rubber products, plastic products, cultural and educational supplies and building materials.X-Type Cationic Dyes
