History of reactive dye:
On the occasion of 100 year’s celebration
of synthetic dye manufacturing, two chemists of ICI company (UK) named Stephen
and Rattee tried to manufacture a new dyestuff. Thus they succeed to invent a
new dye in 16965, which was named REACTIVE DYE. This was manufacture for dyeing
cellulosic fabrics. The first three reactive dyes were PROCION YELLOWR, PROCION
BRILLIANT RED 2B and PROCION BLUE 3G.for this effort they were awarded gold
medal of the society of dyes and colorists for the year 1960.
·
Reactive Dyes :
- Form a covalent bond between the dye and fiber
- Introduced to the market by ICI in 1956.
- Inspired by esterification of cellulose in 1895 with benzoyl chloride
- Show improved fastness properties
- Great improvement for cellulosic fibers
- Simplify dyeing procedure
- No oxidation / reduction.
