Pigments are mainly synthetic organic materials. It has no affinity to the fabric. For this reason, binder is used for making film on the pigment surface. A 3-dimensional cross linking is produced between fiber and pigment. After drying, curing is done at 150 – 180 degree Celsius for fixing the pigments on the fabric surface. Pigment printing is cheaper than other printing process.
