basic introduction

Pigments are used to color powdery substances. It is insoluble in water, grease, resin, organic solvents and other media, but it can be evenly dispersed in these media and can make the media color, but also has a certain hiding power.

Dyes are colored substances. But colored substances are not necessarily dyes. As a dye, it must be able to attach a certain color to the fiber. And it is not easy to fall off and change color.
