The materials used for coloring in ancient China can be divided into mineral pigments and vegetable dyes, the latter being the main dyes of ancient times. The pigmentation of mineral pigments is adhered to the surface of the fabric by a binder, but the color is easily peeled off when exposed to water. Plant dyes are not. When dyeing, the pigment molecules change the color of the fibers by affinity with the fabric fibers. The color is not easily peeled off or rarely falls off after being washed by the sun.
The mineral dyes commonly used in ancient times are numerous. The dyeing processes created by the ancients according to different dye characteristics include: direct dyeing, mordant dyeing, reduction dyeing, anti-dyeing, and color dyeing. The diversity of dye varieties and process methods makes the chromatogram of the ancient printing and dyeing industry very rich. There are hundreds of records in ancient books, especially in a color tone, which clearly separates dozens of approximate colors, which requires skillful mastery. The combination, formulation and changing process conditions of various dyes can be achieved.
