Color-changing clothes: thermosetting fabric in action!

Do you want to know how clothes can change color? This is the magic of thermosetting fabric. The secret is thermochromism — microcapsules are enclosed in fabrics that contain two types of dye: ordinary and thermochromic. Thermochromic dye consists of a leuco dye, weak acids and salts dissolved in dodecanol. When heated (about 24°C), the salt dissociates, the pH drops, and the thermochromic dye changes color. Warm areas change color depending on the combination of dyes. For example, red + yellow = orange. Thermosetting fabric has been around for a long time, but brands are still finding new uses for it. For example, clothes that change color under the influence of heat, the sun, or even your mood!
