Embodiment 1

[0016] The dyeing agent is indigo powder, the additive is distiller's grains, the diluent is distilled water, amylopectin is selected, indigo powder, starch and distiller's grains are added to the reaction vessel, diluted with warm water and stirred evenly, and sealed for 10-20 hours. A white emulsion is formed, and the white emulsion is an environmentally friendly dyeing slurry for printing and dyeing blue cloth, and the slurry needs to be kept airtight. When printing and dyeing, the environmentally friendly dyeing paste will first dye the cloth into white, and the cloth will appear blue after air oxidation.

[0017] Durable blue fabrics dyed with this eco-friendly dye paste won't fade easily. It will not have adverse effects on the human body, and the pigment is easy to degrade and will not pollute the environment.

Embodiment 2

[0019] The dyeing agent is ground safflower powder, the additives include hydrogen chloride and sodium hydroxide, the diluent is distilled water, pullulan is selected, the ground safflower powder is added to the reaction vessel, and excess distilled water is added Mix and stir, after standing for 1-2 hours, put the upper layer solution separately, add starch and sodium hydroxide aqueous solution to the remaining viscous mixed solution and stir evenly to make an environmentally friendly dyeing slurry that can print and dye red. Before printing and dyeing, the additive hydrogen chloride needs to be added to the environmentally friendly dyeing slurry. Specifically, an aqueous solution of hydrogen chloride and hydrochloric acid can be added to make the pH value reach 5-6, so that the environmentally friendly dyeing slurry can be used for printing and dyeing.

[0020] Safflower has the function of promoting blood circulation, dissipating blood stasis and relieving pain. For amenorr...

Embodiment 3

[0022] The ground safflower powder in Example 2 is mixed with distilled water, and the upper layer solution left to stand is distilled and stored to obtain a relatively thick mixed solution, and the mixed solution is mixed with starch to obtain a mixture that can The slurry used for printing and dyeing yellow cloth, needs to add sodium hydroxide solution to it before using the slurry, so that the yellow pigment in the mixed solution can be separated out for printing and dyeing, and the yellow cloth printed and dyed with this environment-friendly dyeing slurry will also have Some of the aforementioned safflower benefits.

Abstract

The invention provides an environment-friendly dyeing slurry, which belongs to the technical field of textile printing and dyeing slurry. The environment-friendly dyeing slurry is prepared by mixing a dyeing agent, starch, an additive and a diluent, wherein the dyeing agent is powder of a natural dyeing material and the starch is natural starch. Since the environment-friendly dyeing slurry provided by the invention is prepared from purely natural raw materials, the dyeing slurry is environment-friendly, produces no pollution and has a dyeing function; and the slurry is a dyeing slurry of a specific color and shows different printing and dyeing colors as different dyeing agents are used.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing auxiliaries, in particular to an environment-friendly dyeing slurry. Background technique [0002] With the progress of society, the pollution of the world's environment is becoming more and more serious, and the wastewater produced by the printing and dyeing industry contains dyes, pastes, additives, fiber impurities, oil agents, acids and alkalis, and inorganic salts, etc. The water quality is complex and the concentration of organic matter is high. , refractory to biodegradation, color depth, and rapid and irregular changes in water quality. If it is discharged arbitrarily, it will cause great pollution to the surrounding environment. At the same time, some new materials are constantly used in printing and dyeing materials, and their hazards cannot be fully evaluated sometimes. When people use it, it will endanger people's physical and mental health, such as some early hair dyes, cl...
