Analyzing the Combustion Characters of Fire Protective Clothing Exposed to Flash Fire

Abstract:

Combustion characters such as afterflame, color fading, thermal shrinkage, carbonization, smoke production provide a comprehensive reflection of the garment performance as a whole. Based on the flame manikin testing system, six kinds of garments which can be divided into two groups (PSA clothing and aramid clothing) were used for combustion experiments, and the combustion characters were analyzed under the same exposure conditions. Results show that the after flame time of PSA clothing was longer than that of aramid clothing, showing poorer flame resistant performance. Large areas of color fading happened to most of the test samples. The average thermal shrinkage of the PSA clothing is greater than the aramid clothing with similar weight and weaving structure. Clothing with larger fabric gram weight and thickness tends to have smaller shrinkage degree. The carbonization degree of PSA clothing was more serious than that of aramid clothing. Smoke amount may relate to the dying and finfish of fabric.
