Temperature changing yarn

Kingbird Temperature Changing Yarn can transition to different beautiful colors on exposure to a range of temperature. For example, our blue color temperature sensitive thread changes instantly to white when touched with warm hands.

In a cool place with a temperature below 16°C, the white color thread returns blue.

Kingbird temperature color changing yarn has two pigments to create colors; one is the base and the other is a temperature sensitive pigment. When the two pigments are mixed, this color appears at a temperature under 16°C.

On the other hand, at over 30°C, the temperature sensitive pigment becomes colorless.
