Problems solved by technology

[0002] Warmth-preserving clothing is usually divided into passive warmth-keeping and active warmth-keeping. Passive warmth-keeping is mainly to keep warm by increasing the thermal resistance of clothing, such as adding clothes. This method makes the clothes thick and affects the wearer's activities; Phase change materials, electric energy, etc. Although the above methods can maintain long-term heating, they are not suitable for washing, and the chemical energy method cannot be reused. The preparation process of phase change materials is complicated, and electric energy heating needs to carry additional power supply energy.
