Brief introduction of dyes
Dyes are colored substances, but colored substances are not necessarily dyes. As a dye, it must be able to attach to the fiber with a certain color, and it is not easy to fall off and change color. Dyes are usually soluble in water, and some dyes need mordants to adhere to fibers. Dyes and pigments absorb some wavelengths of light, so they look colored.
Archaeological data show that dyeing technology has a history of more than 5000 years in India and the Middle East. At that time, dyes came from animals, plants or minerals and were rarely treated. Most dyes come from the plant kingdom, but these dyes are rarely widely used in business.
