Advantages of the Reactive Dyes
Dyeing cycle and Important factors/phases in Reactive Dyeing
Bifunctional Dyes - Dyestuffs containing two groups are known as bifunctional dyestuffs. These reactive dyes are designed in such a manner to have the capacity to react with the fibre in more than a single way.
Vinylsulphone Dye (VS) - Vinylsulphone Dyes are moderately reactive. The dyeing temperature is generally 600C and pH is 11.5 that gets applied by utilising a mixture of soda ash and caustic soda. These dyes show excellent fixation properties under proper alkaline condition. A typical example is the Remazol Black B (CI Reactive Black 5)
Monochlorotriazine Dye (MCT) - Normally these dyes are less reactive than vinylsulphone dyes. Reaction can take place in more energetic reaction conditions. That is typically 800 degreeC and pH value of 10.5, are essential for a proper fixation on cellulosic fibres. A typical monochlorotriazine dye is shown here.
