Embodiment 1

[0053] A reactive dye cold pad-batch printing method, the application process includes: (1) use pure sodium alginate and reactive dyes to prepare color paste for printing and drying; (2) directly pad the dried fabric with a color-fixing alkali agent and Carry out coiling, with a rolling surplus rate of 45%. During the coiling process, a plastic film is used for isolation. After coiling, it is stacked at 35°C for 4 hours; (3) After stacking, it is washed in cold water for 2 times at a temperature of 30-40°C. Then carry out hot water washing→soap washing→hot water washing, the temperature is 85-95 ℃, and dry the cloth. Its color-fixing alkali agent components and weight percentages are as follows: alkali supply agent is sodium hydroxide 5%, sodium carbonate 10%, buffering agent is sodium citrate 15%, chelating agent is sodium ethylenediamine tetramethylene phosphate 5% %, the dispersing detergent is fatty alcohol sulfate 5%, alkali-resistant penetrating agent fatty alcohol polyo...

Embodiment 2

[0055] A reactive dye cold pad-batch printing method, the application process includes: (1) use pure sodium alginate and reactive dyes to prepare color paste for printing and drying; (2) directly pad the dried fabric with a color-fixing alkali agent and Carry out coiling, with a rolling surplus rate of 51%. During the coiling process, plastic film is used for isolation. After coiling, it is stacked at 35°C for 3 hours; (3) After stacking, it is washed in cold water for 2 times at a temperature of 30-40°C. Then carry out hot water washing→soap washing→hot water washing, the temperature is 85-95 ℃, and dry the cloth.

Abstract

The invention discloses a reactive dye cold pad-batch printing method and belongs to the technical field of textile printing and dyeing. A fabric is directly printed through color paste mixed through pure sodium alga acid and reactive dyes, after being dried, the fabric is subjected to pad-batch through a cold pad-batch printing fixation alkaline agent and then piled for 2-4 hours at the temperature of 30-40 DEG C, and then fixation can be finished. Compared with a traditional reactive dye printing method, the reactive dye cold pad-batch printing method has the advantages that steaming fixation is not needed, the energy source is saved, the fixation rate is increased by 7-20%, and dye is saved. The fixation alkaline agent is prepared from, by weight, 5-20% of an alkaline supply agent, 5-20% of a buffering agent, 3-10% of a chelating agent, 3-10% of dispersion abluent, 1-3% of alkali-resisting penetrant and the balance water.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a reactive dye cold pad-batch printing method. Background technique [0002] Reactive dyes have complete chromatograms and bright colors. When used in printing, they have the advantages of convenient preparation of color paste, simple printing process, less defects, better fastness to wet treatment, lower printing cost, and easy color matching. At present, it has become the most important dye for printing cellulose fiber and its blended fabrics. [0003] The reactive dye printing process is divided into one-phase method and two-phase method. At present, the vast majority of printing and dyeing enterprises use the one-phase method for printing. The one-phase method is to mix dyes and alkali agents (usually soda ash or baking soda) together and adjust them into color paste for printing. The main process includes "modifying color paste→printing→ Dry...
