Xiao Bian recently looked at the information and saw that now scientists have developed clothing fabrics that change color according to people's moods. When this technology matures, perhaps when we are in a good mood, clothes will turn into bright colors such as red and green. If we are in a bad mood, It will turn into a dark gray color like gray black. Xiao Bian does not know that such apparel fabrics will be studied when it will be available. However, as consumers increase the level of apparel beauty pursuit, the requirements for clothing colors are also changing from practical to novel types. New types of color-changing fiber materials have been studied by scientists. It may not change with the change of mood, but the color of clothing will change from regular "static" to looming "dynamic" due to changes in light, temperature, and humidity , so that cool skills will be put into production. It is loved by people in the textile circles and fashion circles. Let's look at the color change material with Xiao Bian today!  The type and principle of color changing materials: ( 1) Photosensitive materials The photochromic material is a functional dye that can be discolored under the irradiation of ultraviolet rays or visible light, and can be reversed to the original color after the rays disappear. The photochromic materials mainly include silver chloride, silver bromide, stilbene, spirocycles, 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 structure of these four kinds of light-change materials is closed-loop type, that is, no color is printed on the fabric, and it becomes purple, yellow, blue, and red when irradiated with ultraviolet rays. ( 2) Thermochromic materials The reason why the thermochromic material can change color is that the discoloration body can cause a change in the internal structure, resulting in a change in color, and when the temperature is lowered, the color is restored. Relative to photosensitizing dyes , there have been many studies on thermal dyes at home and abroad. In particular, textile printing has achieved certain results. A series of thermal printing products have been introduced. ( 3) Humidity-sensitive color changing materials The main reason for the discoloration of the humidity-sensitive color-changing material is that the humidity in the air causes the structure of the dye itself to change, so that the absorption spectrum of visible light in the sunlight changes, and the environmental humidity catalyzes the discoloration of the discoloration body. The main component of the humidity-sensitive color-change dye discoloration printing paste is a color-changing cobalt double salt, and the discoloration body is firmly adhered to the fabric by an adhesive during application. In order to make the discoloration sensitive, it is necessary to add a certain sensitizer to help the discoloration body to complete this process, and also add a certain chromophore to improve the vividness of the color of the color-changing fabric. If you combine the color-changing paints in the print paste, and use it for towels, bath towels, handkerchiefs, beachwear, etc., you can get a unique print pattern. I don't know if you still remember the principle of the very popular color changing towel in the circle of friends.  The development of color-changing dyes: The color-changing dyes used in textiles are mainly thermochromic dyes, photochromic dyes and moisture-sensitive color-changing dyes. However, due to the poor rubbing fastness and fastness to washing of these dyes, in the last century, microcapsule technology was introduced into the preparation of color-changing dyes, making the application of color-changing dyes in textiles a qualitative leap forward. Compared with printing and dyeing technology, color-changing fiber technology has obvious advantages: the fabric made has good hand feeling, good washing resistance, and long-lasting discoloration effect. At present, there are also spectrochromic dyes used for dyeing, and more cationic dyes and acid dyes. These dyes have different reflectance peaks at different wavelengths, and thus exhibit a significant spectral discoloration effect, so as to achieve the effect that the yarns assume different colors under different lights. Widely used color changing materials in the textile industry: ( 1) Discolored clothing The discolored clothing was first developed by the U.S. Department of Defense as a soldier's "invisible clothing," which can change color with the surrounding environment. After the 1980s, color-changing garments have been widely used in the civilian field. For example, Toho Manmade Fiber Co., Ltd. in Japan developed a color-changing garment called “Silk is Iraq†that changes color when irradiated with ultraviolet rays; The company has created a thermochromatic and color-changing swimwear that changes in various colors at different temperatures; British material scientists have developed a liquid crystal garment fabric that has unpredictable colors in the range of 28 to 33°C. . After entering the 21st century, the development of color-changing garments has made greater progress. For example, Japan has studied a photochromic dye that can “stain†synthetic fabrics with the colors of the surrounding scenes and “blend†people’s clothing in natural scenery. British scientists have processed liquid crystal microcapsules into inks that can be printed and dyed, coated on a black fiber surface, and displayed fascinating colors with changes in body parts and body temperature changes; After weaving the garment material, the color can be changed with the light source. ( 2) Brand-name clothing identification anti-counterfeiting technology The "UV invisible text pattern", "temperature change recognition", and "feeling three-dimensional text" technologies can be used to identify authenticity through a bill validator or hand touch in a specific part of the trademark , and if necessary, "infrared detection" can be added, greatly increasing the technology. content. The application of this technology in anti-counterfeiting has greatly protected the production interests of regular manufacturers. Let those fakes have nowhere.  The bright future of color-changing materials :  Color-changing fiber materials are high-tech functional fibers that have been rapidly developed and are highly viable in recent years. They have high added value and high efficiency. With the continuous introduction of high-tech, the color-changing fibers will continue to develop and improve. Regarding color-changing dyes, there are not many color-changing dyes that are directly used in textile processing. The main reasons are the high price of dyes, unsatisfactory high temperature and light fastness, poor reusability and stability, and slow color fading. With the increasing demand for gentrification and individuation of garments and the increasing demand for functional finishing fabrics, the development of new color-changing fiber materials and color-changing dyes will have good prospects for development and broad application prospects.
