The Application Range of Thermal manikin

The research of thermal manikin mechanism plays a vital role in the developing of occupational protective clothing.The garment could reduce the thermal loss from human body to the environment through study the structure of thermal manikin,test principle as well as its performance under all wearing condition. Currently the thermal manikin has been widely used in textile garment industry for testing the thermal performance of clothes.

The thermal manikin provides detailed information form its data system. the manikin itself is not equipped with fingers and face. However, it has higher testing strength. There are nearly 700 millions pure nickel wire from fingers to its nasal area. the test accuracy during the test process is high assured by the independent intelligent electric circuit. The built-in circuits in each sector guarantees the test accuracy, and the built-in thermal conductivity system ensures good uniformity. Meanwhile, the manikin can be divided into two parts for the convenience of transporting.

Main application:

Under the fire hazard, people need to wear thermal protective clothing to shield the burning damage. Thermal protective clothing are widely used by firefighters, steelworkers and workers engaged in other high-temperature dangerous situations.As the time of clothes exposed to flame increases, the surface temperature of the garment will gradually rise due to the direct burning flame, and large amount of thermal transmission leads to the surface temperature rising of the air layer beneath the clothes as well as human body.  Under the burning of flame, the garment will appear physical heat property change on its textile which in turn affects its thermal protective property. Also after taking away from the flash fire, the garment still retains a high range of surface temperature, which forms a temperature difference with the temperature under the clothes and human body temperature, consistently generating thermal transmission to continue the temperature rising of human body.Studies have shown that burns can occur after a flash fire, and the energy stored in the fabric is also an important factor in predicting burns.Therefore, even though the thermal protective clothing can withstand the fire for a short time, the clothing can still cause burns to occur during the cooling process.So it is very important to study the temperature changes of clothes and human body after burning.

The study of multi-layer protective clothing using thermal manikins shows that the outermost layer of fabric has an important influence on the protective performance of multi-layer protective clothing.Using the TPP instrument, it is found that it is more prone to be burned exposed to a heat source with low heat flux  fora  long time than intense combustion for a short-term. In the actual wearing process, the thermal protection of clothing depends not only on the performance of the fabric itself, but also on the design, specification and attitude of clothing. In order to truly simulate the situation of human body in the actual fire and measure the surface temperature of  clothing and  human body safely and accurately,  the test method of thermal manikin shows the advantages, widely used in the field of thermal protection.
