Receptive Dyes frame a covalent bond between the color and fiber. It contain a receptive gathering (regularly trichlorotriazine), either a haloheterocycle or an initiated twofold bond, that, when connected to a fiber in a soluble color shower, shapes a compound bond with a hydroxyl bunch on the cellulosic fiber.
In a responsive color a chromophore contains a substituent that is enacted and permitted to specifically respond to the surface of the substrate. Responsive coloring is currently the most essential technique for the shading of cellulosic filaments. Responsive colors can likewise be connected on fleece and nylon; in the last case they are connected under feebly acidic conditions. Responsive colors have a low usage degree contrasted with different sorts of dyestuff, since the utilitarian gathering likewise bonds to water, making hydrolysis.
Advantages of reactive dyes

Permanency of the color
Good chemical binding
Allows for a large variety of chromophores to be used
Types of reactive dyes
Bifunctional Dyes - Dyestuffs containing two gatherings are known as bifunctional dyestuffs. These receptive colors are outlined in such a way to have the ability to respond with the fiber in more than a solitary way.
Vinylsulphone Dye (VS) - Vinylsulphone Dyes are modestly receptive. The coloring temperature is for the most part 600C and pH is 11.5 that gets connected by using a blend of pop fiery debris and acidic pop. These colors show phenomenal obsession properties under legitimate antacid condition. An ordinary illustration is the Remazol Black B (CI Reactive Black 5)
Responsive DyesMonochlorotriazine Dye (MCT) - Normally these colors are less receptive than vinylsulphone colors. Response can occur in more vivacious response conditions. That is normally 800 degreeC and pH estimation of 10.5, are key for a legitimate obsession with cellulosic filaments. A run of the mill monochlorotriazine color is appeared here.
