Beimian photoelectron down jacket filler
By adding special substances into the fiber to absorb solar energy and convert it into heat energy, it emits far infrared rays with long wavelength, which warms the interior of clothes. Heat can be absorbed, stored and released in the form of latent heat by adding heat-sensitive phase change materials to fibers. In the process of temperature change, it can change from solid to liquid, thus achieving the effect of heat absorption and heating.
At present, most of the electric down jackets sold in the market use electric heating wires or carbon fiber materials, which have low heating efficiency and high power consumption. The biggest disadvantage of using this material is that it cannot be bent often, nor can it be exposed to the sun for a long time, otherwise it may cause local overheating and even fire. If there is a fire in the down, the consequences are unimaginable.
