Thermochromic Dyes

Thermochromic dyes are smart colorants that change color in response to temperature variations. In the textile industry, these dyes are incorporated into fabrics to create materials that visually react to changes in heat, offering both functional and aesthetic advantages. When exposed to specific temperatures, thermochromic textiles can shift from one color to another or become transparent, revealing patterns or underlying designs. This reversible color change is driven by molecular rearrangements within the dye’s structure or phase transitions in the microencapsulated systems used to apply them.
