Pigments are mainly synthetic organic materials. It has no affinity to the fabric. For this reason, the binder is used for making a film on the pigment surface. A 3-dimensional cross-linking is produced between fiber and pigment. After drying, curing is done at 150 – 180 degrees Celsius for fixing the pigments on the fabric surface. Pigment printing is cheaper than other printing processes.
Here, I have given a sequence of pigment printing on the cotton fabric.
This is a sample printing recipe. It can be changed depending on the color depth.
- Thickener: 2%
- Binder: 8%
- Fixer: 2%
- Water: 90%
