      According to our knowledge on dyes, we came to know about the specific properties or the criteria to identify a chemical whether it is dye or not.

      please have some discussions about the key criteria for a chemical to be a dye.

      Fiber-reactive dyes form strong covalent bonds with cellulosic fibers, which result in good wash fastness. Reactive dyes are subject to hydrolysis, which is the chemical reaction of the dye with the water. Hydrolysis must be controlled for dye optimization. A wide range of reactive dye chemistries is available, resulting in a range of performance attributes.
