Abstract

The invention belongs to the technical field of printing and dyeing industry, and particularly relates to a reactive dye printing paste for flat net or rotary screen printing and a preparation method of the reactive dye printing paste. The reactive dye printing paste comprises the following components in mass by weight: 1-20 percent of reactive dye, 3-25 percent of cosolvent, 0.1-5 percent of anti-dyeing salt, 1-10 percent of printing paste and the balance of water, wherein the reactive dye comprises one or more of a read reactive dye compound, a yellow reactive dye compound, an orange reactive dye compound and a blue reactive dye compound. The printing paste can be stored for a long time without degrading; and a cellulosic fiber fabric is subjected to printing and steaming fixation, the fixation rate of the dye is remarkably increased, the wet processing fastness is improved to certain extent, and the condition of contaminating white bottom by the dye is improved to certain extent.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing industry. Specifically relates to a reactive dye printing color paste for flat screen or rotary screen printing and a preparation method thereof. Background technique [0002] The printing and dyeing industry uses reactive dyes to produce flat screen or rotary screen printing on cellulose fiber fabrics, and currently direct printing is the main method. [0003] Reactive dyes need to prepare printing paste for direct printing of cellulose fiber fabrics on flat screen or rotary screen. In printing paste, K-type and P-type reactive dyes are generally used, and sometimes KN-type or M-type reactive dyes are also used, and these reactive dyes are used Dyes and printing pastes need to add alkaline agents such as sodium bicarbonate, sodium carbonate, etc., to fix the color in steam. Due to the addition of alkaline agent in the printing color paste, the storage stability of the printing colo...
