• a mercerized and bleached cotton fabric is impregnated with an aqueous solution of 50 parts of sodium hydroxide and 100 parts of the monosulfate of 2,3-dihydroxy-1-aminopropane in 1000 parts of water at a temperature between 25 and 30 ° C with a liquor absorption of 85% and then to Fixation of the aminopropane compound on the fiber material treated with hot air at 150 ° C. for about 3 minutes, the impregnated fabric drying at the same time.
• the modified material is then freed from excess alkali by treatment with cold water at 60 ° C.
• the thus modified, dried material is passed under a stainless steel sheet with the aid of a rubber roller and printed in one operation with the aqueous solutions of fiber-reactive dyes in the basic colors of the subtractive color mixture by means of an ink jet print head which works according to the "drop on demand" process.
• the web is then passed through a continuously working microwave dryer for fixation.
• the dyed material can then be finished by washing; however, a short, hot wash bath and subsequent drying is usually sufficient.
• the fabric obtained shows a very sharp color print of the chosen pattern; the dye itself has good wash fastness.
• the fabric obtained shows a very sharp color print of the chosen pattern; the dye itself has good wash fastness.
• a cellulose fiber material modified according to the invention such as, for example, a cellulose fiber material modified in accordance with the above exemplary embodiments, is printed on using the procedure of an inkjet printer, for example analogously using one of the methods described in the above exemplary embodiments, using aqueous solutions of one or more known dyes specified in the table examples below (the dyes are written in the form of the free acid; however, they are used in the form of their alkali metal salts). Clear, strong-colored print samples are obtained with the color shade given in the respective table example and the fastness properties, in particular good fastness to washing, which are good for the respective dye.
