Optimization of Discharge Printing Recipe on Cotton Fabric Dyed with Eco-Friendly Reactive Dye

Decorating fabrics by dyeing and printing are very ancient arts, which in modern time have received considerable help from science and have shared in the forward surge of technology. Printing, a method of ornamentation employed first by ancient Indians and Egyptians, can be broadly classified on the basis of methods and styles. Textile printing is the process of applying colour to the fabric in a definite pattern or design. It may be regarded as a specialized technique of dyeing. The main idea of printing is to deliberate and control application of dye to exactly defined location on the fabric leaving the rest of the fabric essentially unaffected. In dyeing, colour is applied in the form of solution, whereas in printing, colour is applied in the form of a printing paste of the dye and thickener.
