Abstract

The invention discloses a reactive dye printing method for cellulose fiber fabric based on microwave color fixation, which comprises the following steps: mixing reactive dye, cationic nanospheres, paste and water to prepare dye liquor, and then carrying out printing treatment on the cellulose fiber fabric pretreated by alkali liquor to obtain printed fabric; and finally, completely dipping the printed fabric in a mixed solution of liquid paraffin and trimethyl hydroxyethyl ammonium chloride, carrying out microwave color fixation, washing for the first time, soaping, washing for the second time, and shaping. The reactive dye is used for printing the cellulosic fiber fabric, the microwave color fixing effect is good, energy consumption of ageing color fixing is avoided, urea is not used, and the method is more environmentally friendly.

Description

technical field [0001] The invention relates to a cellulose fabric printing method, in particular to a reactive dye printing method based on microwave-fixed cellulose fiber fabrics. It belongs to the technical field of printing and dyeing. Background technique [0002] Reactive dye printing is a common printing method. Reactive dyes contain reactive groups that can react with fiber molecules. During the printing process, the reactive groups of reactive dyes combine with fiber molecules to form a whole with dyes and fibers. The printing process of reactive dyes is simple, the color is bright, and the color is easy to match. Therefore, in the process of printing with reactive dyes, it is usually necessary to add printing auxiliaries, and the amount of printing auxiliaries will directly affect the brightness, uniformity, and dye uptake of the final printing. [0003] Traditional reactive dye printing basically uses steaming to fix the color, specifically using a fast steamer ...
