Abstract:

In order to ensure both thermal protection performance and thermal wet comfort performance of the firefighter protective clothing, 7 kinds of outer fabrics for firefighter protecive clothing were selected for the study. Each single index of thermal protective performance and comfortable performance related indicators of the fabrics were tested, and the influences of factors such as fabric material and performance parameters on thermal protection performance and comfort performance were analyzed, and its influence law was expounded. A fuzzy comprehensive evaluation method was used to evaluate the thermal protection performance and comfort performance of the fabrics. The results show that the thermal protection performance of the fabric is related to the composition, thickness and compactness of the fabric, and the comfort performance is mainly related to the fabric density and compactness as well as thickness and gram weight of the fabric. Among the seven kinds of fabrics tested, aramid ante-static fabric is the best in comprehensive performance, while the performance of acrylic fiber/cotton blended peotective fabric is the poorest.
