Abstract

The invention discloses an activated dye resist printing technology for a cotton fabric. The technological process comprises the following steps in sequence: printing, drying, ageing, washing with water, soaping and drying. The formula of the coating white resist paste comprises the following components: 200-400 g / kg of coating white, 150-300 g / kg of an adhesive, 150-300 g / kg of an emulsion thickener, 60-80 g / kg of sodium sulfate; the formula of the coating color resist paste comprises the following components: 200-400 g / kg of a coating, 160-250 g / kg of an adhesive, 40-50 g / kg of an emulsion thickener as a thickener, 30-80 g / kg of sodium sulfate, 200-400 g / kg of an activated dye as printing paste, 400-500 g / kg of 5% sodium alginate paste, 5-10 g / kg of appropriate urea reserve salt S, and 10-25 g / kg of sodium bicarbonate. The requirements on the activated dye for resist printing comprise low affinity to cotton fiber, and low probability of cleaning the unfixed dye.

Description

technical field [0001] The invention belongs to printing technology, in particular to a cotton fabric reactive dye printing technology. Background technique [0002] In cotton fabric reactive dye printing, the following situations are often encountered: safflower green leaves and blue ground safflower collide with opposite or contrasting colors, but the third color is not allowed to be produced; thin hook lines that are lighter than the ground color are printed , Hemming; a pattern composed of multiple colors and with a fixed outline, it is difficult to obtain a continuous and smooth effect on the outline only by matching flowers. In addition, when printing special patterns such as inverted patterns, fine small flowers and leaves in dark colors, and light-colored veins on cloth, these colors are rich in layers and have a strong three-dimensional effect. , using the principle of resist printing for resist printing. Traditional anti-printing printing is prone to color spots ...
