Disperse dyes are water insoluble

and also dispersible in water

High energy dyes become soluble > 160 C

Medium energy dyes become soluble > 140 C

Low energy dyes become soluble > 110 C

They are THERMO- SOLUBLE (Thermosol)

Reactive dyes are water soluble but

are hydrolyzed by water

Pigment Colors are water insoluble

but dispersible in water

(3)

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 printing

Pigment 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 with the binder.

A high pH using volatile amines such ammonia as an important role in print productivity, especially in hot conditions.

Water insoluble Pigment particles surrounded by the binder film

Synthetic Fiber

Pigment particles do NOT diffuse into the fibers

Binder adheres to the outside of the fibers Pigment particles are surrounded within the binder film

Cure for 5mins @ 150C

Binder pigment ratios High binder ration, better crocking

PIGMENT BINDER FILM

Pigment particle 0.3- 0.5 microns, binder film minimum 0.5 micron thickness
