PIGMENT DYEING
BACKGROUND V
Pigment dyeing is not really " dyeing" in it's truest form.
V
Pigments are insoluble in water. They are milled into a paste for garment dyeing purposes.
V
The process is complete when a binder is added to "lock" the pigment into place.
TECHNICAL DEPARTMENT
V
Pigments are generally used for light to medium dyeing for fully fashioned garments and for indoor cloth such as wall covering, furniture, table cloth and bed sheets…
V
Pigments are also used to achieve dark shades for outdoor fabrics like tents, stores, awnings…
V
The process is attractive when dyeing cotton/synthetics fabrics in a single phase. AVCO VIETNAM May 2006
