N2 - Currently, the thermometer, infrared thermal imaging camera and temperature sensor are the main instruments for the temperature measurement of thermal products. However, these instruments are either inconvenient or too expensive to afford. For researchers, these are common to approach, whereas for designers or salespeople who work in the thermal textile field, new tools that are more convenient to access, easily affordable and have design possibilities need to be invented. This study aims to select a temperature indicator thermochromic pigment amount of four pigments (red, yellow, green and blue) for thermal woven textiles by analyzing the colorimetric properties and making a fast indicator demonstration prototype to achieve the concept. The pigment samples are heated respectively and the decolorization color at 40℃, 50℃, 60℃ and 70℃ under illuminant D65 are real-time measured by a spectroradiometer. The L*, a*, b*, ΔL*, Δa*, Δb*, K/S and color difference CMC 2:1 values are calculated and analyzed. In this experiment, blue pigment has the best performance and thus results in the top selection of the indicator pigment, which is used in production for a fast, convenient and visualized temperature indicator for thermal woven textiles.
