Comfortable Thermal Manikin applications

Comfortable Thermal Manikin ​mechanism research and occupational protective clothing development has played an important role. From the structure of the warm body dummy, testing principles degree of use and other aspects of the synthesis of the warm body dummy in all wearing conditions, clothing to reduce the heat loss from the body to the environment, the current warm body dummy in the textile and apparel industry is more widely used, the individual aspects of the user clothing testing is very effective.

Comfortable Thermal Manikin ​can test detailed data system, the dummy itself does not come with fingers and face, the dummy has a higher strength, the dummy inside the dummy from the fingers to the nose placed close to 700m of pure nickel wire, independent intelligent circuitry to ensure the accuracy of the measurement process. The independent intelligent circuitry ensures the accuracy of the measurement process. The internal circuitry in each part ensures the accuracy of the measurement, and the built-in heat conduction system ensures a good uniformity. At the same time the dummy can be divided into two parts, easy to transport.

Studies on multi-layer protective clothing using combustion dummies have shown that the outermost fabric has a significant impact on the protective performance of multi-layer protective clothing. Tests using the TPP apparatus revealed that prolonged exposure to heat sources with low heat flow is more likely to result in burns than short periods of intense combustion. In the actual wearing process, the thermal protection performance of clothing does not only depend on the performance of the fabric itself, but also needs to be considered in terms of clothing style design, specifications and dressing posture. In order to simulate the human body in the actual fire as realistic as possible as well as safe and accurate determination of clothing as well as the surface temperature of the human body, the burning dummy test method shows the advantages, in the field of thermal protection has been widely used.

Main applications of comfortable Thermal Manikin:

In the fire hazard environment, people need to escape from flame damage by wearing thermal protective clothing. Thermal protective clothing is widely used to protect firefighters, steelworkers and staff working in other hot and dangerous situations. As the exposure time of the clothing increases, the surface temperature of the clothing will gradually increase due to the direct burning of the flame, and the large amount of heat transfer makes the air layer under the clothing and the surface temperature of the human body increase at the same time.

Not only will the thermal and physical properties of the fabric itself change under the flame burn and affect its thermal protection properties, but also after leaving the flash fire environment, the surface temperature of the garment will remain in a higher range and form a temperature difference with the temperature under the garment and the surface of the human body, continuing to produce heat transfer to the surface temperature of the human body continues to rise.

Studies have shown that burns can occur after the flash fire is over, and that the energy stored in the fabric is also an important factor in predicting burns. Therefore, even though thermal protective clothing can resist the flame for a short period of time, the garment can still cause burns during the cooling process. Therefore, the study of the temperature change of the garment as well as the human surface after burning is particularly important.
