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.
Here, I have given a sequence of pigment printing on the cotton fabric.
Recipe: This is a sample printing recipe. It can be change depending on the color depth.
Sequence of Pigment Printing: Pigment printing is carried out as the following way.
