Abstract: Combustion characters such as afterflame, color fading, thermal shrinkage,
carbonization, smoke production provide prehensive 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 bustion
experiments, and bustion 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.
