The invention discloses a temperature-sensitive color-changing paint dyeing technology of textile fabrics. The process flow is as follows: selection and composition of the temperature-sensitive color-changing paint; preparation of temperature-sensitive color-changing dye microcapsules; preparation and dyeing of a temperature-sensitive color-changing pigment printing paste, dehydration, and baking to obtain a temperature-sensitive color-changing fabric. The textile fabric is a fabric which is prepared by pretreatment of cotton, Tencel fiber, modal fiber, chemical fibre blended cotton (lanca, polyester cotton and nylon cotton), silk, wool and the like. Through combined actions of ambient temperature, temperature inside clothes and body temperature, the color of the temperature-sensitive color-changing textile obtained by the application of the dyeing technology changes when the surface temperature of the textile achieves or exceeds color-changing temperature; and when the temperature drops below the color-changing temperature, the textile turns to the original color. With the change of the temperature, the textile fabric shows unexpected color and pattern, and the pattern will change based on movement of the body. The color-changing fabric can be widely applied in T-shirt, trousers, swimsuit, casual gym suit, working clothes, children's clothing, curtain, toy and the like.
