Sun Active T-shirts are fun shirts! Not hyper colour tops, t-shirts switch shade in the sun. Colour shifting t-shirts change the colour effortlessly when subjected to sun's UV rays. Inside, the pattern is painted in rigid ink, and afterwards, the sun colours emerge when revealed outside. Sounds exciting and fun, right? Well, summers are here with its clothing perks! In reality, these T-shirts have been here since the late 1980s. Now, some businesses have heavily invested in innovation and also have developed better technologies and a better experience.
These Sun Active T-Shirts for women are the latest trend. There are many such t-shirt variants with multiple prints on them, half of which is visible to the naked eye without the sun and the other half evolves under the sunlight. Sounds magical to me.
T-shirts which change colour in the sunlight are immensely popular, particularly in some geographical regions. They make beautiful souvenirs and that for both children and young adults, they are a great novelty item. Nevertheless, several people are mind baffled by the thought of a T-shirt which changes colour in sunlight.
The colour used while dying the heat-changing T-shirts is termed a thermochromic colour. Or put it more simply, thermochromic implies that with differences in temperature, a chemical alteration in the element allows it to change colour. The same idea is applied in mood rings, flat thermometers as well as other measures of weather. When it is used in fabric production, these pigments result in a garment that changes colour if approached by a gentle caress or worn outdoors in the heat.
There are only two different colours that are used in the dying process of these T-shirts. The first is the one you see when the T-shirt is hot, the lasting one. And it is a standard colour, but the temperature-sensitive pigment masks this. The change is due to a chemical change triggered by the heat that momentarily blocks the thermochromic dye's image. The thermochromic pigment is in microcapsules, which becomes part of the fabric of T-shirts. Some microcapsules change drastically to become translucent with the sun. The mixture of the thermochromic dye and the lasting dye is the colour you see at temperature once the tee is cold.
How do these T-Shirts work?
The crystal of Spectra Chrome shows colour when ultraviolet rays irradiate; i.e., sunlight. The impact when a flower blossom is showing the flower's natural colour. Spectra chrome crystal is identical in that there is a power-shift allowing the dye's colour to become visible to the naked eye. The dye's move or “twisting” is termed a transfer from chemical excitation. In reality, the pigment may not “transform” colour; it will become visible to the naked eye instead. No specific connection is expected here between wavelengths of light, therefore, triggers a particular shade of the ink and the colour of the ink. Many artificial lights on the UV are relatively thin, but if you want to check this experimentally, black views are readily available.
