Dyes and Pigments

Dyes and Pigments are generally compounds that have their own color and can make other substances obtain a bright and firm color in the molecular state or dispersed state. Dyes are organic compounds that can dye fibers or other substrates to a certain color. They are mainly used for dyeing and printing fabrics. Most of them are soluble in water, or converted into a soluble state during dyeing through certain chemical treatments. Pigments are colored organic or inorganic colored compounds that are insoluble in water and general organic solvents. "Dyes and Pigments" on Echemi mainly supplies raw materials for dyes and pigments.


Dyes refer to a class of organic compounds that can give other substances a bright and firm color. Since the dyes used today are all synthetic, they are also called synthetic dyes. The color of the dye itself does not represent its color on the fabric. "Dye" on Echemi mainly supplies raw materials for dyes.


Pigments are soluble and insoluble, there is a difference between inorganic and organic. Inorganic pigments are generally mineral substances. Humans have long known the use of inorganic pigments, using colored earth and ore, to paint and smear the body on rock walls. Organic pigments are generally taken from plants and marine animals, such as Ruby blue, Garcinia cambogia, and purple from the shells of ancient Rome. The color of the pigment itself represents its color in the substrate. "Pigments" on Echemi mainly supplies raw materials for pigments.
