Basic introduction
A powdery substance used to pigment. It does not dissolve in water, grease, resin, organic solvents and other media, but can disperse evenly in these media and make the media color, and it has a certain hiding power.
Dyes are colored substances. But colored substances are not necessarily dyes. As a dye, it is necessary to be able to attach a certain color to the fiber. And it is not easy to fall off and discolor.
