Introduction
The sweating thermal manikin test system simulates the physical mechanism and heat exchange from the outside world. Obtain the thermal resistance, wet resistance and clo value of the material by the manikin monitoring results, and the influence of different clothing on the thermal comfort manikin is obtained by analyzing the software data.
Thermal manikin test system can characterize the impact of different clothing on human comfort performance by measuring the heat balance and the results of human comfort between heat generation of dressed manikin and the external environment. Then, guide the fabric and clothing development for the special using conditions of the comfort.
Thermal manikin test system with data analysis software present human sensory conclusions through the data. It avoids the real human test to achieve the uniform data results. Reduce the difference in results caused by differences in personal perception.
It is applicable to thermal insulation properties test of functional fabrics, clothing R & D and production, sleeping bags and other materials, It also can be used to analyze the environmental impact on human comfort and the environmental conditions that meet the comfort of the human body.
The United States, Canada, the United Kingdom, France, Germany, Russia, Switzerland, Sweden, Denmark, Finland, Norway, Hungary, Poland, Portugal, Japan, South Korea, Singapore and other countries have make this advanced technology apply to clothing, aerospace, fire, traffic safety and other fields. Especially in the hot and humid comfort evaluation and the development of occupational protective clothing. Thermal manikin can simulate the heat exchange process between human body, clothing and environment in the setting environment, scientifically evaluate the thermal performance of the whole clothing, avoid the influence of individual differences in human experiment with high experimental precision and good reproducibility. It has recognized as an indispensable means for the study of garment ergonomics.
Human body dissipates heat to the surrounding environment not only by the conduction, convection, radiation, but also by the body's skin sweat evaporation. If the water vapor can spread through the clothing system in time to the surrounding environment, we will feel comfortable. If the clothing hinders the passage of water vapor, increasing micro-climate humidity between the human skin and clothing, water vapor will accumulate to a certain extent and condensate into the water to make people feel uncomfortable. When the human body carry out intense activities or in a hot environment, the sweat evaporation is an important way to lose calories. Therefore, the clothes are asked to have high water vapor transmission capacity. Thus, it is necessary to accurately test the evaporation resistance of clothing in order to make a comprehensive evaluation of the heat and moisture transfer performance.
