dyestä
Dyes are coloring substances that chemically bond to the substrate being colored. This bonding is a key characteristic that distinguishes dyes from pigments, which are insoluble particles that color by dispersion. Dyes are typically soluble in water or another solvent, and they are applied in a solution. The color of a dye is due to its molecular structure, which allows it to absorb certain wavelengths of light and reflect others. The reflected wavelengths are what we perceive as color.
Historically, dyes were derived from natural sources, such as plants, animals, and minerals. Examples include indigo
Dyes are classified based on their chemical structure, dyeing method, or application. Common types include acid
The application of dyes is a crucial process in many industries, most notably in textiles, but also
