Abstract
A method for photocatalytic white discharge printing for achieving patterns on textiles includes closely integrating substrates with patterned printing plates or fixing patterned printing plates on one or both sides of a substrate, placing them in a reactor equipped with a light source and containing the photocatalytic white discharging formulation. The method has the characteristics of a simple process, short processing, easy controlling and wide adaptability. The process eliminates the need for printing plates and expensive printing apparatus used in complicated conventional printing methods. Additionally, the photocatalytic solution can be reused which avoids generous application of chemical agents and waste discharges that are present in conventional printing methods. The method is beneficial for cutting costs, saving energy, reducing emissions and has cleaner production.
