A dye is an organic compound whose main function is to dye textiles. The main function of the pigment is to color the non-woven fabric. Because the dye can directly act on the textile, the textile has a good affinity for the dye, and the fiber molecules in the textile can absorb the dye, so that the dye can be fixed on the fiber molecule. Pigments do not have this effect and therefore cannot be used on textiles.
One of the biggest differences between dyes and pigments is that dyes can be dissolved in the medium, while pigments cannot be dissolved in the medium. In layman’s terms, when we dye textiles, we first dissolve the dyes in water, and dye the textiles through the colored liquid dissolved in water. When dyeing oily wax or plastics, dyes must be dissolved in alcohols or oily liquids before dyeing oily waxes or plastics.
Unlike dyes, pigments are insoluble in the medium. When pigments are used to color non-woven fabrics, they mainly rely on resins or adhesives, which can form films, to combine with objects that need to be colored, so as to achieve Coloring effect.
The color of both dyes and pigments is also different from the color that finally colors the object. The color of the dye itself may be different from the final color, because the dye has to go through a process of dissolving in the medium when dyeing. This means that the dye goes through a process from a solid state to a liquid state. Therefore, the color represented by the dye itself in a solid state may be different from the final dyed color.
The pigment does not need to be dissolved, it exists in a solid state from beginning to end, so its own color is the color formed after the final coloring of the object. According to this principle, we should pay more attention to the original color of the pigment not to degrade when preserving the pigment, and there is no such need when preserving the dye, even if its original color changes, as long as the color does not change after being dissolved in the medium, there is no need to overfill Worry.
