Reactive Dyes Manufacturer The Reactive Dyes manufactured and marketed by VAP CHEM which consists of Vinyl Sulphone Based, Cyanuric Chloride Based (H/P and HE), Bi-Functional type and Speciality series like VD and VBG Series. Vinyl Sulphone Reactive Dyes are recommended for Pad-Batch Silicate Process, Printing and also most of the dyes are suitable for Exhaust Dyeing too. Cyanuric Chloride Based Reactive Dyes consists of H/P series which are suitable for printing, while HE dyes are suitable for Exhaust Dyeing.
Reactive Dye has better stability properties due to the molecular bondage during the dyeing process. The reactive dyes are usually used in the coloring of cellulose such as cotton, wool, and nylon. Reactive dyeing is a well-accepted method for the coloration of cellulose fiber because it connects itself to its substrate by chemical reaction to form a covalent bond between the dye and fiber molecules. The color thus becomes a part of the fiber and reduces the likelihood of its removal or extinction while washing it compared to coloration by the adsorption method. This formation of covalent bonds with substrate to be colorful is one of the most important characteristics of Reactive Dyes. Properties of reactive dyes:
1. Reactive Dye is anionic in nature.
