    • Improved textile materials are produced having white or variously colored designs on a colored substrate on textile materials containing hydrophobic, synthetic fibers by impregnating the materials with dye liquors containing dyeing and padding auxiliaries as well as dyestuffs dischargeable to white, drying or incipiently drying the impregnated materials and then printing a desired pattern onto the materials with a discharge reserve paste containing a discharging agent, and subsequently subjecting the materials to a heat treatment at temperatures from 100.degree. to 230.degree. C., the improvement comprises the dyestuffs dischargeable to white being dyestuffs of the formula ##STR1## wherein n is a number from 1 to 9; and said discharging agent being a base which produces a pH value of at least 8 in a 5% strength aqueous solution.
    • 通过用包含染色和填充助剂的染液浸渍材料以及可排放成白色的染料,干燥或初始干燥浸渍的材料,在含有疏水性合成纤维的纺织材料上的着色基材上制造改进的纺织品材料 然后用含有放电剂的放电储备膏将所需的图案印刷在材料上,随后在100℃至230℃的温度下对该材料进行热处理,改进之处在于可以将可排出白色的染料作为染料 式其中n为1至9的数; 并且所述排出剂是在5%强度的水溶液中产生至少8的pH值的碱。
