摘要:
An improved process for preparing discharge prints on textile materials containing hydrophobic fibers wherein at least one disperse dyestuff dischargeable to white is applied to the textile material in the form of a dyeing liquor of print paste and also contacted by a pattern-applied discharge resist print paste, and then the material is heat treated at 100.degree. to 230.degree. C., wherein the improvement comprises said discharge resist print paste having, under the heat treatment conditions, a pH value of zero to 3.
