Different types of dyes are used for different textile fibers based on the characteristics of the fiber. For example, acid dyes are used for protein-based fibers like silk and wool because they bond well with the amino groups in these fibers. Reactive dyes are used for cellulosic fibers like cotton because they form covalent bonds with the hydroxyl groups in cellulose, providing good wash-fastness. Disperse dyes are used for synthetic fibers like polyester because they have low solubility in water and can penetrate the hydrophobic surface of these fibers.
