35 u00b0 and 55 u00b0 being in a solution in the proportion of between 34 and 70 g of sulfuric acid at 66 u00b0 be and 30 60 g of oxalic acid per liter accompanied by an energetic dispersing agent of the same features as that which appears in the reducing method the process is then finished with the same washing finishing and drying processes as were stated in the reducing method by increasing the concentrations of acid in the paste and the temperature in the drying installation the initial strength to the fibers or yarns making up the fabrics can be changed this strength may be kept the same by merely reducing the temperature and the acid concentration to the level stated to adjust the fastness to washing of the coloring effects obtained the conditions of setting must be changed especially the temperature and the moisture content in the vaporizer if we vary these we can also vary and control the fastness which will increase when the temperature and moisture contents are increased and vice versa the textile stock dyed with indigo blue and then discharge printed using the procedure described herein not only has a visible very attractive high quality finish but also a gentle feel the same as the stock had previous to being treated in this manner this is not what occurs with stock dyed with indigo blue which are overprinted in which the feel is much worse as in the printed areas the.
