COLORIMETRIC CHANGES OF THERMOCHROMIC INK PRINTED ON SMART TEXTILE MATERIALS EXPOSED TO DIFFERENT HEAT TRANSFER METHODS
The paper presents the study of the temperature influence on the colorimetric properties of leuco dye-based screen printing thermochromic ink to determine the printing parameters that will give a good colour response during the cooling of the heated samples. Four specific groups of textile materials were used and the colorimetric properties of magenta leuco thermochromic water-based screen printing ink (activation temperature 31°C) were analysed. On the basis of a color differences analysis it is confirmed that the screen mesh count influences the change of the color on the material in such a way that the mesh count is higher the color change is faster, the sample returns faster from the discolored to the colored state. It has also been confirmed that the smaller the surface mass of the material is, the sample returns faster from discolored to the coloured state.
