In a reactive dye, a chromophore (an atom or group whose presence is responsible for the colour of a compound) contains a substituent that reacts with the substrate. Reactive dyes have good fastness properties owing to the covalent bonding that occurs during dyeing. Reactive dyeing is the most important method for coloring cellulose fibers.
Colorfast dyes are dyes resistant to shifts in hue, fading, or bleeding (transfer of dye) when wet. [12] copperas Copperas is the dyer's name for ferrous sulfate, an iron mordant used to sadden or reduce the saturation of colors. [4] [13] crimson Crimson is a deep red dye or color derived from the word kermes. [14] [15] [16] crottle
The covalent bonds that attach reactive dye to natural fibers make them among the most permanent of dyes. "Cold" reactive dyes, such as Procion MX, Cibacron F, and Drimarene K, are very easy to use because the dye can be applied at room temperature. Reactive dyes are by far the best choice for dyeing cotton and other cellulose fibers at home or ...

Vinyl sulfone dyes are reactive dyes comprising a vinyl sulfone group as reactive group (a fiber-bonding site of the reactive dye, "reactive hook"). Due to the relatively high reactivity of the vinyl sulfone group with water (residual moisture, air humidity), it is present in many commercial products in a protected form.
It currently contains over 27,000 individual products listed under 13,000 Colour Index Generic Names. [2] It was first printed in 1925 but is now published solely on the World Wide Web . The index serves as a common reference database of manufactured colour products and is used by manufacturers and consumers, such as artists and decorators.
