Pigment printing is generally referred to as the printing option applied on polyester fabrics. The printing process with dyestuffs is done in one step by direct printing method and etching method.
Pigment dyestuffs are a very important class of dyestuffs in cotton printing and are generally insoluble in water and organic solvents, and have no affinity for textile fibers. For this reason, they are attached to the fiber with resin-based adhesives called binders. They are then subjected to a high temperature condensation process. The fastness properties of pigment dyestuffs are largely dependent on that of the binder. The quality and correct use of the binder directly affect the fastness properties.

Where is Pigment Colorant Used?
They are dyestuffs that can be used for almost all fiber types and mixtures. The difficulties encountered in printing with other dyestuffs do not exist in these dyestuffs. It is preferred because of the low cost of fixation and post-processing. However, the negative effect of binders on sensitive materials can be considered as one of its disadvantages.
