Poolin Temperature Changing Embroidery Thread will show different colors at a certain temperature. For example, if you touch the red temperature changing thread with your hand, the color will change to white. When the ambient temperature is higher than 31°C, the thermosensitive colorant in it will change color. Normally, temperature sensitive thread will return to its original color when the ambient temperature is lower than 20°C. It is a novel and unique yarn which makes your embroidery product better. Can be used for high temperature alerts, like high temperature warning for baby water bottle, also fashion color sensitive shoelaces. The discoloration effect will gradually weaken and can last for about 3 months if used frequently.
