Problems solved by technology

Now there are many coatings suitable for rotary screen printing, but they still have many shortcomings: coatings are chemically synthesized substances that are not safe and environmentally friendly, and toxic chemicals will be released during use, which will endanger human health
The disadvantage of the dye is that the pigment in the dye is an industrial synthetic pigment, which is poisonous and harmful to the human body, and it is not environmentally friendly.

Abstract

The invention discloses an environment-friendly rotary screen printing coating. The environment-friendly rotary screen printing coating is formed by mixing 50-300 ml of plant pigment, 5-20 g of a natural thickening agent, 30-250 g of a water soluble bonding agent, 5-20 g of a wetting agent, 120-260 g of pearl powder, 1-10 g of nanometer TiO2 and 1L of water. The environment-friendly rotary screen printing coating has the main advantages that the plant pigment is adopted, so that safety and environmental protection are achieved, the phenomenon that synthetic dyestuff or petrifaction dyestuff releases toxic and harmful substances in the using process is avoided, the method is simple and efficient and can extract pigment from plants for preparing the coating, and the water soluble additive agent is adopted, so that damage caused by adopting formaldehyde to the human body is avoided.

Description

technical field [0001] The invention relates to a cloth coating, in particular to an environment-friendly rotary screen printing coating. Background technique [0002] At present, in the field of industrial production, rotary screen printing can be operated continuously, and the printed fabric can be continuously processed from the bottom of the cylinder, which is the printing method with the fastest production speed. In order to ensure the quality of printing and make the pattern have good color, gloss and color fastness, the coating for rotary screen printing must be formulated. Among the paint components, binders, thickeners, wetting agents and pigments have the greatest influence on the characteristics of the paint, and play a decisive role in the effect of the final pattern. The binder makes the pigment adhere to the surface of the fabric, the thickener changes the viscosity of the pigment to control the physical properties of the pigment, and the wetting agent ensures...
