This is to report on the result of the attempt intended for even the beginners to succeed easily in white discharge printing on textiles of vegetable fiber by using `Rongalite C.' I dyed the cotton cloth for discharging by the reactive dye beforehand. I observed the state where the discharge paste dried gradually. These are the efforts I have made to find an easy method which produces clear white ground. The results are summarized as follows.1)The thickness of the paper pattern used in order to discharge is not so important.2)When a discharge paste is thinly applied to cotton cloth, a discharge pattern appears sharply, but when it applies thickly, the outline of a discharge pattern fades.3)Time required for desiccation of a discharge paste is about 2 hours.4)Use of a steam iron has an effect in a discharge.5)After applying the discharge paste to cotton cloth, when it was made to dry several days, although I did not iron, I was able to do white discharge printing.
