Nowadays, women generally wear thinner clothes. Even if it is cold, they don't want to add more clothes. It is impossible to add a warm sticker. This phenomenon reflects the current people's potential demand for heated clothing. Heated apparel is no longer purely a kind of functional clothing or unique professional clothing but a product that enters the lives of the public and becomes a substitute for down jackets.
Electric heating clothing is a general term for clothing that connects power supply, temperature control devices, safety protection devices, heating elements, etc., through wires to form a circuit and uses the power supply to control the heating elements inside the clothing to generate heat. The appearance of electric heating clothes is no different from ordinary clothes, but there are more heating sheets (flexible heating fabric), connecting wires, and batteries than regular clothes. The heating sheet and the connecting line are sewn and fixed on the clothes interlayer. The connecting port is generally set on the inner side of the clothes to connect the external battery (power bank), and the small button switch is placed on the surface of the clothes. The heating principle of electric heating clothes is: the mobile power supply provides electric energy, and the heating piece converts the electric energy into heat energy to achieve the purpose of heating and keeping warm. The method of realizing electric heating clothes is mainly to connect heating elements, temperature control devices, safety protection devices, etc. into lines through wires, and use power to control the heating elements in the clothes, thereby converting electrical energy into heat energy, achieving the purpose of actively supplying heat. In electric heating clothing, the heating element is one of the most critical structures. At present, there are three types of heating elements that are most used in the field of clothing heating: carbon fiber heating sheets, graphene heating sheets, and carbon nanotube electric heating films to achieve electric heating effects.
The mobile power supply provides energy. The heating element (soft heating sheet) of the electric heating suit converts electric energy into heat energy to provide heat to the body, keep the body warm, and resist severe cold. The temperature control device can adjust the temperature of the electric heating suit. The user can change the most suitable and comfortable temperature according to the ambient temperature and his situation. There is a safety protection device in the electric heating suit. When the temperature is high, it will automatically jump to the low gear to keep the temperature at a warm level. When it detects that the user stops using it, it can automatically cut off the power, so you don't need to worry about if you forget to turn off the power. It is also designed with multiple protections like overvoltage, overcurrent, and short-circuit, which are very safe to use.
In the twelfth lunar winter, many workers involved in special types of work have to face low temperature and severe cold work, such as freezer workers, traffic coordinators, security guards, drivers driving motor vehicles, troops at border posts, military police, and field prospectors, and polar regions. Investigators, divers, etc., all face the same problem-keeping warm from the cold. The clothing itself does not generate heat, and the electrically heated clothing can continue to heat the human body, making people feel warm all the time. Therefore, it is vital to develop an electric heating suit that can automatically provide a heat source. The thermal performance of the electric heating clothing we set will not make the human body feel uncomfortable, and it is in line with the principles of human physiological hygiene.
Electric heating gear is no longer purely a kind of functional clothing or unique professional clothing but a product that enters the lives of the public and becomes a substitute for down jackets. Heating gear mainly includes chemical, thermal clothing, solar thermal clothing, and electric heating clothing. Among these three types of heating clothing, electric heating clothing is superior in its performance.
