Classes Of Disperse Dyes
by : Rahul Sharma
Clasees Of Disperse Dyes:
1. Low Energy (E type):
These dyes have low molecular weight, low polarity, high dyeing rate and low sublimation fastness.
2. Medium Energy (SE type):
These dyes have moderate molecular weight, moderate polarity, moderate dyeing rate and moderate sumblimation fastness.
3. High Energy (S type):
These dyes have high moolecular weight, high polarity, low dyeing rate and high sublimation.
Disperse dyes are used mainly for polyester, but also for cellulose (acetate and triacetate), polyamide and acrylic fibers.
