The fabric used in the thermal protection experimental clothing in the study is a flame retardant aramid outer layer fabric, which is blended with 93% aramid 1313, 5% aramid 1414 and 2% P-140 conductive carbon fiber, with stable flame retardant properties, Wear resistance and antistatic properties [1-2]. In the experiment, three kinds of fabrics with different gram weights were used to make thermal protective clothing, and the basic parameters are shown in Table 1.
It is the classification, fabric and size code of 10 sets of experimental clothing, among which clothing A, B, and C represent the successive increase of 80 inches in the latitude direction. The specific clothing size details are shown in Table 3.
In this experiment, 10 sets of thermal protective clothing were used as experimental clothing samples. The design and implementation organization of experimental clothing combined with experimental conditions are shown in Table 4. The experiment is carried out according to the relevant requirements of ISO13506-2008
In this experiment, the infrared thermal imager is mainly used to observe the surface temperature of the clothing, and the Burning dummy system is used to collect and analyze the surface temperature of the human body.
The infrared thermal imager is fixed before burning, and then the dressed burning dummy is exposed to a flash fire environment, and the temperature change between the clothing surface and the dummy surface is recorded through the thermal imager and the dummy system. The thermal imager captures the frontal part of the dummy. The temperature area of 105 degrees is selected for the thermal image, and the selected location area corresponds to the combustion dummy sensor, and a total of 35 temperature areas are selected on the front of the dummy.
