Reversible thermochromic textiles are one of the remarkable advancements in Smart Textiles. In this study, a new approach was explored to produce reversibly thermochromic cotton fabrics suitable for smart textile applications by studying commercial leuco-based thermochromic dyestuff through conventional pad-dry-cure method. Effects of varying dyestuff concentrations, crosslinking agents, and migration inhibitors were systematically investigated to optimise thermochromic responsiveness and durability. Scanning electron microscope (SEM) analyses confirmed the dyestuff presence on the cotton fibres. Incorporation of binder significantly improved the dyestuff’s adherence to the cotton fibres. Fourier-Transform Infrared Spectroscopy (FTIR) validated the presence of thermochromic dyestuff on cotton fibres. The dyed cotton fabrics exhibited phase transition temperatures (approximately 30 °C) very similar to that of thermochromic dyestuff. Regarding thermochromic performance, all dyed samples demonstrated high responses, exhibiting clear colour changes when heated from 20 °C to 40 °C. The colour changes were preserved even after 100 heating–cooling cycles and after multiple washing cycles, confirming enhanced durability. Results demonstrated that pad-dry-cure method can successfully impart reversible thermochromic functionality to cotton fabrics. The new method is both feasible and effective in achieving reversible colour changes with satisfactory fastness properties. This approach offers a promising alternative to microencapsulation techniques and contributes to the advancement of sustainable, cost-effective, and functional Smart Textiles by utilizing conventional dyeing infrastructures for fabrication of thermochromic cotton fabrics.
