Reactive dyes was introduced in 1956, primarily belongs to a class of highly colored organic substances. While dyeing the reactive groups of reactive dyes forms covalent bond between fibre polymer and dye which makes dye integral part of fibre. Hence, they are known for its enhanced fastness property. These dyes have stable electron arrangement which protect fibre from the adverse effect of ultra-violet rays. The significant chemical bonding improves the overall color stability and washability of the product makes these dyes most permanent of all other dye types. Undoubtedly, it is one of the most popular dyes used in textile industry all across the world.
REACTIVE ‘ME’ Dyes
Reactive ‘ME’ Bi Functional Series dyes are suitable for dyeing, padding & printing of all types of cellulosic material. They offer high grade of all round fastness properties. They have an advantage of high degree of exhaustion & fixation rates. They offer excellent leveling properties & excellent alkali stability. They give highly reproducible dyeing because of better alkali stability & low sensitivity to temperature.
