What is the difference between organic pigments and dyes?
The traditional use of dyes is the dyeing of textiles, and the traditional use of pigments is to color non-textiles, this is because the dye has affinity for the textile, fiber molecules can be adsorbed, fixed, while the pigment pile of all colored objects are no affinity, Mainly by resin, adhesives and other film-forming substances and coloring objects combined with the dye in the course of the general use of the first dissolved in the use of media, even disperse dyes or vat dyes, in the dyeing is also experienced from a crystal state first Dissolved in the water into a molecular state and then dyed on the fiber on the process.Therefore, the color of the fuel itself does not mean that it is in the fabric color / pigment in the use of the process due to insoluble in the use of media, so always the original crystal state The color of the pigment itself represents the color of the pigment on the substrate.Now the production of pigments in the world has been growing, the domestic production of organic pigments enterprises have begun to increase, the domestic more representative Such as Jiangsu De Choi Pigment Chemical Co., Ltd. and so on.
