What are the color-changing materials?

The principle of color changing materials, what are the color changing textile materials? In recent years, with the improvement of consumption levels, everyone's pursuit of beauty has also changed a lot. The color of clothing is becoming more and more strict. According to the requirements of the market, the textile industry is also developing rapidly, and a large number of fabrics have appeared. Let's take a closer look at the small series below.

(1) Photochromic material The photochromic material is a functional dye which can change color under the irradiation of ultraviolet light or visible light, and can be inverted to the original color after the light disappears. Photochromic materials mainly include silver chloride, silver bromide, stilbene, spiro, norbornadiene, fulgides, triphenylmethane derivatives, salicylic acid aniline compounds and the like. At present, photochromic materials have been developed to have four basic colors: purple, yellow, blue, and red. The initial structures of the four kinds of optically variable materials are closed-loop type, that is, there is no color on the fabric, and it becomes purple, yellow, blue, and red when exposed to ultraviolet rays.
(2) Thermochromic material The reason why the thermochromic material can change color is because the color changing body can cause a change in the internal structure, thereby causing a change in color, and when the temperature is lowered, the color is restored. Compared with photosensitive dyes, there are much more researches on thermal dyes at home and abroad, especially in the application of textile printing, and a series of thermal printing products have been available.
For example, the RT series produced in China is a thermochromic product. In the process of taking the fabric, depending on the season and region, the indoor and outdoor temperatures are different, and the color is changed. At present, the color printing materials can be produced and the processing technology is mainly in the UK, Japan, etc. and Taiwan in China.
(3) Humidity-sensitive color-changing materials The main reason for the discoloration of moisture-sensitive color-changing materials is that the humidity in the air causes the structure of the dye itself to change, so that the absorption spectrum of the visible portion of sunlight changes, and the environmental humidity has a certain catalysis for the discoloration of the color-changing body. effect. The main component of the moisture-sensitive color-changing dye-changing printing paste is a color-changing cobalt double salt, and the color-changing body is firmly adhered to the fabric by an adhesive during application. In order to make the color change sensitive, it is necessary to add a certain sensitizer to help the color changing body to complete the process, and also add a certain coloring body to improve the vividness of the color of the color changing fabric.
