Reactive dyes properties
WebThe dyeing process must place dye molecules within the microstructure of the fibre. The dye molecules can be anchored securely through the formation of covalent bonds that result from chemical reactions between substituents on the molecules of the dye and the fibre. These are the reactive dyes, a type introduced in 1956. Many dye-fibre ... WebReactive dyes have the advantages of bright color, good color fastness, and simple application process [1-5]. Reactive dyes can react with fiber to form a covalent bond between fiber and dye. Covalent bonds are formed between dye molecules and -OH groups of cellulose fibers and become an important part of it.
