for DISPERSE DYES
Disperse dyes are water insoluble and also dispersible in water High energy dyes become soluble > 160 CMedium energy dyes become soluble > 140 CLow energy dyes become soluble > 110 CThey are THERMO- SOLUBLE (Thermosol)
Reactive dyes are water soluble but are hydrolyzed by water
Pigment Colors are water insoluble but dispersible in water
SOLUBILITY
The three primary components for pigment printing pastes are •Pigment dispersion• Binder•Thickener
Pigment particles are dispersed in water with chemicals such as glycols, emulsifiers, dispersants, etc., to give stable dispersions. (Pigment dispersion)
Pigment printingPigment print pastes are sensitive to increases in temperature and must not be mixed for long periods (heat generation) they should be stored in a cool place and kept covered to prevent skin formation on the paste surface by warm air interacting withthe binder.
A high pH using volatile amines such ammonia as an important role in print productivity, especially in hot conditions.
