Gouache pigments are busy flying, and all kinds of materials show new colors.

In order to enable children to master all kinds of art skills, improve their eye-hand coordination ability, have good color sense and aesthetic ability, and achieve synchronous education between parents and kindergartens, the senior class group of Gaoming Kindergarten in the town recently launched a half-day opening activity of "gouache paint is busy flying, all kinds of materials show new colors. In terms of material selection, according to the age characteristics of children in large classes, each class is mainly composed of gouache with rich colors and difficult operation, supplemented by various materials. Class 1 focuses on environmental protection and uses plastic water pipes (which can be used repeatedly), paper tubes, popsicles, plush wire, beans, cloth and other materials to create. The teachers provide disposable aprons so that children can use cotton swabs to point and draw their favorite patterns in the game. Class 2 is mainly composed of forest department, mainly pushing cartons, fans, cold hats, straws, disposable chopsticks, buttons, etc.

What are the vat dye dyeing methods

Vat dyes can be used for dyeing cotton and polyester-cotton and cotton blended fabrics. According to the different forms of dye, it can be divided into leuco dyeing method and suspension pad dyeing method. There is also a leuco acid staining method, which is not commonly used, so it is not discussed here. 1. leuco dyeing leuco dyeing is a dyeing method in which the dye is reduced to leuco in advance, adsorbed by the fiber in the dye bath, and then oxidized and soaped. It can be divided into dip dyeing, roll dyeing and pad dyeing, etc., and is currently mostly used for dip dyeing and roll dyeing. Leuchrome dip dyeing is suitable for yarn dyeing, but the dyeing method has poor core penetration and white core phenomenon. Depending on the nature of the dye, different reduction methods can be used.

Performance Index and Determination Method of Reactive Dyes

High quality reactive dyes should have good water solubility. The solubility and the concentration of the prepared dye solution are related to the selected bath ratio, the amount of electrolyte added, the dyeing temperature and the amount of urea. Reactive dyes used in printing or pad dyeing should be selected with a solubility of about 100g/L. The dyes are required to be completely dissolved, not turbid, and not colored. Hot water can accelerate dissolution, urea has a solubilizing effect, salt, sodium sulfate and other electrolytes will reduce the solubility of dyes. When the reactive dye is dissolved, the alkali agent should not be added at the same time to prevent the dye from hydrolyzing.

Environmentally friendly dyes should include the following ten aspects

(1) Does not contain the German government and the European Community and Eco-Tex Standard 100 expressly stipulated that under certain conditions will crack to release 22 kinds of carcinogenic aromatic amines, whether these carcinogenic aromatic amines free in the dye or by the dye cleavage of azo dyes; (2) not allergic dyes; (3) not carcinogenic dyes;

Dye Oily Metal Complex Dye Color Essence/Toner

Due to the particularity of the complex structure of metal complex dyes, which is different from the general organic pigments and traditional azo dyes, it has higher gloss and transparency, better weather resistance and stronger fastness. Compared with inorganic pigments, metal complex dyes have the characteristics of easy dispersion, easy penetration, easy coloring, bright color and good transparent effect.

Environment-friendly metal complex water-based dye knowledge popular science

Environment-friendly metal complex water-based dyes are divided into three series, with complete colors. Pure water-based dyes only need to be dissolved and dispersed directly with water. Metal complex water-based powder dyes can be dissolved in solvents such as ethylene glycol ether/methanol/ethylene glycol/dimethylformamide, or can be dissolved by adding water and solvent. They have excellent solubility, good compatibility with various resins, bright colors, good acid resistance, alkali resistance and heat resistance, and no free heavy metals. According to the needs of different industry products to provide powder and liquid two categories, and for different requirements of supply, liquid dye (color essence) easy to use, no dust pollution.

Chemical methods for various dyes

1. direct dyes: direct dyes have relatively good heat resistance stability. direct dyes can be dissolved by adding soda ash soft water. when mixing materials, the dyes are first mixed into slurry with cold soft water, then boiled with soft water, stirred and dissolved, diluted with heated water, and then added with water to the specified liquid volume after cooling.
