Description:
With the developed of liquid crystal thermometer,there comes a new type of LCD thermometer which called clothes thermometer.It will show you the clothes’ level of insulation by green color after you wear the clothes 15 seconds later,help you to choose a suitable clothes in winter .
How to use garment thermometer?
Sewing/Heat transfer printing the garment thermometer inside of the garment.
Then you can see the warmth of the garment after wearing it through the green
Color shows on the thermometer.
What are Liquid Crystal?
Liquid crystals possess the mechanical properties of a liquid,but have the optical properties of a single crystal.Temperature changes can affect the color of a liquid crystal,which make them useful for temperature measurement.
There are two stages in the liquid crystals:
- the hot nematic stage is the closest to the liquid phase where the molecules are freely moving around and only partly ordered.
- The cold smectic stage is closest to a solid phase where the molecules align themselves into tightly wound chiral matrixes.
Liquid crystal thermometers portray temperatures as colors and can be used to follow temperature changes caused by heat flow.They can be used to observe that heat flows by conduction,convection,and radiation.
